    There was general jubilation at CERN following the announcement from Stockholm on 17 October that Carlo Rubbia and Simon van der Meer had been nominated for the 1984 Nobel Prize for physics by the Royal Swedish Academy of Sciences 'for their decisive contributions to the large project which led to the discovery of the field particles W and Z, communicators of the weak interaction'. These discoveries, made last year at CERN, rank among the greatest achievements in the history of science

    Alfred Nobel never spoke publicly about his problems of ill health, but a detailed, subjective record has recently been published in the form of 216 letters written to his mistress during an 18-year period. His descriptions of constant pain, debilitating migraine, and "paralyzing" fatigue permit a hypothesis that he might have had a long struggle with fibromyalgia. This does not preclude his having suffered other illnesses as well. He thought he had heart disease, which his physicians denied until his final years, when he was diagnosed with angina pectoris. He died of a cerebral hemorrhage in 1896 at the age of 63. His letters describe a 30-year search for diagnosis from the best physicians in Europe. He was ridiculed by many people as a hypochondriac, and he never received a diagnosis for "the pain that will not go away." This may well have contributed to the bitterness and depression of his final years. Increasing worldwide interest and research in this elusive syndrome will hopefully prevent a repetition of the Nobel story of a century ago.

    The theme of the 1995 Nobel Prize for Physics is leptons, the particles which feel the weak nuclear force, best known in nuclear beta decay. The prestigious award is shared by Frederick Reines of the University of California, Irvine, and by Martin Perl of the Stanford Linear Accelerator Center. Professor Reines' award is in recognition of his epic 1956 discovery, made with Clyde Cowan at the Savannah River reactor in South Carolina, that the neutrino, predicted by Wolfgang Pauli in 1930, is a physically observable particle. Unfortunately Clyde Cowan died in 1974. Professor Perl's discovery of the tau lepton at the SPEAR electron- positron collider in 1976 was less expected, but no less important for today's Standard Model of particle physics. The discovery of the neutrino is traditionally described as an experimental verification of a bold theoretical prediction by Wolfgang Pauli. However Leon Lederman has pointed out that it should be the experimentalists who get the lion's share of the credit. Experiments provided the data which 'made it perfectly obvious' that Pauli had to invent the neutrino! Looking at the same data, Niels Bohr was led to suggest that conservation of energy inside the atom would not be absolute. Pauli only made his suggestion out of desperation, says Lederman, adding 'driving a theorist as good as Pauli to desperation has been the goal of red-blooded experimentalists ever since'. With beta decay experiments reporting a tiny energy imbalance, Pauli was driven in 1930 to suggest that an otherwise invisible particle was emitted along with an electron when a neutron decayed into a proton. At first, he was reluctant to talk about a particle which could not be detected, but by 1934 the neutrino had been incorporated into Enrico Fermi's theory of weak interactions. Hans Bethe and Rudolf Peierls calculated the expected absorption rate of neutrinos by nuclei and concluded such particles would be undetectable

    Driven by the inherent synthetic potential of CO2 as an abundant, inexpensive and renewable C1 chemical feedstock, the recent years have witnessed renewed interest in devising catalytic CO2 fixations into organic matter. Although the formation of C-C bonds via catalytic CO2 fixation remained rather limited for a long period of time, a close look into the recent literature data indicates that catalytic carboxylation reactions have entered a new era of exponential growth, evolving into a mature discipline that allows for streamlining the synthesis of carboxylic acids, building blocks of utmost relevance in industrial endeavours. These strategies have generally proven broadly applicability and convenient to perform. However, substantial challenges still need to be addressed reinforcing the need to cover metal-catalyzed carboxylation arena in a conceptual and concise manner, delineating the underlying new principles that are slowly emerging in this vibrant area of expertise. © 2018 WILEY-VCH Verlag GmbH & Co.

    The metal-catalyzed radical addition reaction can be evolved into two different polymerization mechanisms, i.e.; chain- and step-growth polymerizations, while both the polymerizations are based on the same metal-catalyzed radical formation reaction. The former is a widely employed metal-catalyzed living radical polymerization or atom transfer radical polymerization of common vinyl monomers, and the latter is a novel metal-catalyzed radical polyaddition of designed monomer with an unconjugated C=C double bond and a reactive C-Cl bond in one molecule. The simultaneous ruthenium-catalyzed living radical polymerization of methyl acrylate and radical polyaddition of 3-butenyl 2-chloropropionate was achieved with Ru(Cp*)Cl(PPh{sub 3}){sub 2} to afford the controlled polymers, in which the homopolymer segments with the controlled chain length were connected by the ester linkage.

    Full Text Available The Nobel Peace Prize has long been considered the premier peace prize in the world. According to Geir Lundestad, Secretary of the Nobel Committee, of the 300 some peace prizes awarded worldwide, “none is in any way as well known and as highly respected as the Nobel Peace Prize” (Lundestad, 2001. Nobel peace speech is a unique and significant international site of public discourse committed to articulating the universal grammar of peace. Spanning over 100 years of sociopolitical history on the world stage, Nobel Peace Laureates richly represent an important cross-section of domestic and international issues increasingly germane to many publics. Communication scholars’ interest in this rhetorical genre has increased in the past decade. Yet, the norm has been to analyze a single speech artifact from a prestigious or controversial winner rather than examine the collection of speeches for generic commonalities of import. In this essay, we analyze the discourse of Nobel peace speech inductively and argue that the organizing principle of the Nobel peace speech genre is the repetitive form of normative liberal principles and values that function as rhetorical topoi. These topoi include freedom and justice and appeal to the inviolable, inborn right of human beings to exercise certain political and civil liberties and the expectation of equality of protection from totalitarian and tyrannical abuses. The significance of this essay to contemporary communication theory is to expand our theoretical understanding of rhetoric’s role in the maintenance and development of an international and cross-cultural vocabulary for the grammar of peace.

    Full Text Available In the last few years, transition metal-mediated reactions have joined the toolbox of chemists working in the field of fluorination for Life-Science oriented research. The successful execution of transition metal-catalyzed carbon–fluorine bond formation has become a landmark achievement in fluorine chemistry. This rapidly growing research field has been the subject of some excellent reviews. Our approach focuses exclusively on transition metal-catalyzed reactions that allow the introduction of –CFH2, –CF2H, –CnF2n+1 and –SCF3 groups onto sp² carbon atoms. Transformations are discussed according to the reaction-type and the metal employed. The review will not extend to conventional non-transition metal methods to these fluorinated groups.

    The Nobel Prize is awarded annually in recognition of achievements in the fields of medicine, physics, literature, and chemistry, as well as for peace. Since 1901, the best and brightest minds across the globe - 776 of them, in fact - have had the distinct privilege of being honoured by the Swedish Nobel Committee for their work and efforts in these fields. The International Atomic Energy Agency and its Director General, Mohamed ElBaradei, were awarded the 2005 Nobel Peace Prize. Although this is a tremendous achievement for the Agency, it is by no means an isolated one within the UN family. The IAEA award is the eighth time the United Nations or partner international organization has won the Peace Prize. UN Secretary-General Kofi Annan and the UN shared the 2001 prize; the UN Peacekeeping Forces were honored in 1988; the UN Children's Fund (UNICEF) in 1965; the UN High Commissioner for Refugees in 1981 and 1954; and the International Labor Organization in 1969. The late UN Secretary General Dag Hammarskjold won the prize posthumously in 1961

    2013-12-01

    In the summer of 2012, a great discovery emerged at the Large Hadron Collider (LHC) at CERN in Geneva. A plethora of new precision data had already by then been collected by the ATLAS and CMS experiments at LHC, providing further extensive support for the validity of the Standard Model of particle physics. But what now appeared was the first evidence for what was not only the last unverified prediction of the Standard Model, but also perhaps the most decisive one: the prediction made already in 1964 of a unique scalar boson required by the theory of François Englert and Peter Higgs on how fundamental particles acquire mass. At that moment in 2012, it seemed particularly appropriate to start planning a gathering of world experts in particle physics to take stock of the situation and try to answer the challenging question: what next? By May 2013, when the LHC Nobel Symposium was held at the Krusenberg Mansion outside Uppsala in Sweden, the first signs of a great discovery had already turned into fully convincing experimental evidence for the existence of a scalar boson of mass about 125 GeV, having properties compatible with the 50-year-old prediction. And in October 2013, the evidence was deemed so convincing that the Swedish Royal Academy of Sciences awarded the Nobel Prize in Physics to Englert and Higgs for their pioneering work. At the same time the search at the LHC for other particles, beyond those predicted by the Standard Model, with heavier masses up to—and in some cases beyond—1 TeV, had provided no positive result. The triumph of the Standard Model seems resounding, in particular because the mass of the discovered scalar boson is such that, when identified with the Higgs boson, the Standard Model is able to provide predictions at energies as high as the Planck mass, although at the price of accepting that the vacuum would be metastable. However, even if there were some feelings of triumph, the ambience at the LHC Nobel Symposium was more one of

    The 2013 Physics Nobel Prize was awarded conjointly to Englert F. and Higgs, P.W. for the theoretical discovery of a mechanism that contribute to our understanding of the origin of the mass of subatomic particles and which was recently confirmed by the discovery of the predicted Higgs boson in the ATLAS and CMS experiments at the LHC. The Brout-Englert-Higgs (BEH) mechanism allows the conciliation of finite range interaction and then non-null mass with symmetry through the concept of spontaneous symmetry breaking. As mass and couplings are relativist invariants, they stay unchanged in the rotation of the space for instance, the BEH field must be too and as a consequence must be a scalar field associated with a null spin particle called the Higgs boson. As the BEH mechanism explains the mass of elementary particles, it gives no hint about the reason of the broad range of particle masses we observe. (A.C.)

    Transition metal-catalyzed nitrene transfer is a powerful method for incorporating new CN bonds into relatively unfunctionalized scaffolds. In this communication, we report the first examples of site- and chemoselective CH bond amination reactions in aqueous media. The unexpected ability to employ water as the solvent in these reactions is advantageous in that it eliminates toxic solvent use and enables reactions to be run at increased concentrations with lower oxidant loadings. Using water as the reaction medium has potential to expand the scope of nitrene transfer to encompass a variety of biomolecules and highly polar substrates, as well as enable pH control over the site-selectivity of CH bond amination.

    Full Text Available Carbomagnesiation and carbozincation reactions are efficient and direct routes to prepare complex and stereodefined organomagnesium and organozinc reagents. However, carbon–carbon unsaturated bonds are generally unreactive toward organomagnesium and organozinc reagents. Thus, transition metals were employed to accomplish the carbometalation involving wide varieties of substrates and reagents. Recent advances of transition-metal-catalyzed carbomagnesiation and carbozincation reactions are reviewed in this article. The contents are separated into five sections: carbomagnesiation and carbozincation of (1 alkynes bearing an electron-withdrawing group; (2 alkynes bearing a directing group; (3 strained cyclopropenes; (4 unactivated alkynes or alkenes; and (5 substrates that have two carbon–carbon unsaturated bonds (allenes, dienes, enynes, or diynes.

    1997-01-08

    There is a critical need for new environmentally friendly processes in the United States chemical industry as legislative and economic pressures push the industry to zero-waste and cradle-to-grave responsibility for the products they produce. Carbohydrates represent a plentiful, renewable resource, which for some processes might economically replace fossil feedstocks. While the conversion of biomass to fuels, is still not generally economical, the selective synthesis of a commodity or fine chemical, however, could compete effectively if appropriate catalytic conversion systems can be found. Oxygenated organics, found in a variety of products such as nylon and polyester, are particularly attractive targets. We believe that with concerted research efforts, homogeneous transition metal catalyzed reactions could play a significant role in bringing about this future green chemistry technology.

Specimens of human serum albumin (HSA) and pooled plasma were collected from 3 healthy volunteers and 4 uremia patients were divided into 3 groups: Group A incubated with copper sulfate solution of the concentrations of 0, 0.2, or 0.5 mmol/L, Group B, incubated with hydrogen peroxide 2 mmol/L, and Group C, incubated with copper sulfate 0.2 or 0.5 mmol/L plus hydrogen peroxide 2 mmol/L. 30 min and 24 h later the AOPP level was determined by ultraviolet visible spectrophotometry. High-performance liquid chromatography (HPLC) was used to observe the fragmentation effect on plasma proteins. Ninhydrin method was used to examine the protein fragments. The scavenging capacity of hydroxyl radical by macromolecules was measured so as to estimate the extent of damage for proteins induced by MCO. (1) The AOPP level of the HSA and plasma specimens of the uremia patients increased along with the increase of cupric ion concentration in a dose-dependent manner, especially in the presence of hydrogen peroxide (P < 0.05). (2) Aggregation of proteins was almost negligible in all groups, however, HPLC showed that cupric ion with or without hydrogen peroxide increased the fragments in the HAS specimens (with a relative molecular mass of 5000) and uremia patients' plasma proteins (with the molecular mass 7000). (3) The plasma AOPP level of the healthy volunteers was 68.2 micromol/L +/- 2.4 micromol/L, significantly lower than that of the uremia patients (158.5 micromol/L +/- 8.2 micromol/L). (4) The scavenging ability to clear hydroxyl radical by plasma proteins of the healthy volunteers was 1.38 -9.03 times as higher than that of the uremia patients. MCO contributes to the formation of AOPPs mainly through its fragmentation effect to proteins.

    This article traces the origins of the Nobel Prize as a ubiquitous symbol of excellence in science. The public image of the Nobel Prize was created and became established quickly, which can be explained by it being such a useful phenomenon for the co-production of other values and ideas such as national prestige. Through being an easily recognizable symbol for excellence, the Nobel Prize is an important factor for the public image of science. And the image of the Nobel Prize is co-produced with several other sets of values and images that range from the large and thematic to the local and specific.

    2016-04-21

    The metal-catalyzed coupling of alkynes is a powerful method for the preparation of 1,3-enynes, compounds that are of broad interest in organic synthesis. Numerous strategies have been developed for the homo- and cross coupling of alkynes to enynes via transition metal catalysis. In such reactions, a major issue is the control of regio-, stereo-, and, where applicable, chemoselectivity. Herein, we highlight prominent methods for the selective synthesis of these valuable compounds. Further, we illustrate the utility of these processes through specific examples of their application in carbocycle, heterocycle, and natural product syntheses.

In the list below, Bernadette Caldwell of the Editorial Staff suggests additional resources that are available through JCE for teaching the science behind some of the 2008 Nobel Prizes . Discovering and Applying the Chemistry of GFP The Royal Swedish Academy of Sciences awarded the 2008 Nobel Prize in Chemistry for the discovery and development of the green fluorescent protein, GFP to three scientists: Osamu Shimomura, Martin Chalfie, and Roger Y. Tsien. These scientists led the field in discovering and introducing a fluorescing protein from jellyfish into cells and genes under study, which allows researchers to witness biochemistry in action. Now tags are available that emit light in different colors, revealing myriad biological processes and their interactions simultaneously. Identifying HPV and HIV, HIV's Replication Cycle, and HIV Virus-Host Interactions The Nobel Assembly at Karolinska Institutet awarded the 2008 Nobel Prize in Medicine or Physiology for their discovery of human immunodeficiency virus (HIV) to two scientists: Françoise Barré-Sinoussi and Luc Montagnier; and for his discovery of human papilloma viruses [HPV] causing cervical cancer to one scientist, Harald zur Hausen. Diseases caused by these infectious agents significantly affect global health. While isolating and studying the virus, researchers discovered HIV is an uncommon retrovirus that infects humans and relies on the host to make its viral DNA, infecting and killing the host's white blood cells, ultimately destroying the immune systems of infected humans. Related Resources at JCE Online The Journal has published articles relating to GFP specifically, and more generally to fluorescing compounds applied to biochemistry. The Journal has also published an article and a video on protease inhibition—a strategy to suppress HIV's biological processes. With the video clips, an accompanying guide

    high temperatures and long reaction times. To address this issue, we have developed several new families of carbon- and boron-based ligands, which are even better donors. The corresponding metal complexes (particularly gold, rhodium, iridium, and ruthenium) of all these species will be tested in the Markovnikov and anti-Markovnikov hydroamination of alkynes, allenes, and also alkenes with ammonia and hydrazine. We will also develop metal-free catalytic processes for the functionalization of ammonia and hydrazine. By possessing both a lone pair of electrons and an accessible vacant orbital, singlet carbenes resemble and can mimic the chemical behavior of transition metals. Our preliminary results demonstrate that specially designed carbenes can split the N–H bond of ammonia by an initial nucleophilic activation that prevents the formation of Lewis acid-base adducts, which is the major hurdle for the transition metal catalyzed functionalization of NH3. The use of purely organic compounds as catalysts will eliminate the major drawbacks of transition-metal-catalysis technology, which are the excessive cost of metal complexes (metal + ligands) and in many cases the toxicity of the metal.

    Quantum chemical techniques today are indispensable for the detailed mechanistic understanding of catalytic reactions. The development of modern density functional theory approaches combined with the enormous growth in computer power have made it possible to treat quite large systems at a reasonable level of accuracy. Accordingly, quantum chemistry has been applied extensively to a wide variety of catalytic systems. A huge number of problems have been solved successfully, and vast amounts of chemical insights have been gained. In this Account, we summarize some of our recent work in this field. A number of examples concerned with transition metal-catalyzed reactions are selected, with emphasis on reactions with various kinds of selectivities. The discussed cases are (1) copper-catalyzed C-H bond amidation of indoles, (2) iridium-catalyzed C(sp(3))-H borylation of chlorosilanes, (3) vanadium-catalyzed Meyer-Schuster rearrangement and its combination with aldol- and Mannich-type additions, (4) palladium-catalyzed propargylic substitution with phosphorus nucleophiles, (5) rhodium-catalyzed 1:2 coupling of aldehydes and allenes, and finally (6) copper-catalyzed coupling of nitrones and alkynes to produce β-lactams (Kinugasa reaction). First, the methodology adopted in these studies is presented briefly. The electronic structure method in the great majority of these kinds of mechanistic investigations has for the last two decades been based on density functional theory. In the cases discussed here, mainly the B3LYP functional has been employed in conjunction with Grimme's empirical dispersion correction, which has been shown to improve the calculated energies significantly. The effect of the surrounding solvent is described by implicit solvation techniques, and the thermochemical corrections are included using the rigid-rotor harmonic oscillator approximation. The reviewed examples are chosen to illustrate the usefulness and versatility of the adopted methodology in

    From left to right: David Politzer, David Gross and Frank Wilczek. For their understanding of counter-intuitive aspects of the strong force, which governs quarks inside protons and neutrons, on 5 October three American physicists were awarded the 2004 Nobel Prize in Physics. David J. Gross (Kavli Institute of Theoretical Physics, University of California, Santa Barbara), H. David Politzer (California Institute of Technology), and Frank Wilczek (Massachusetts Institute of Technology) made a key theoretical discovery with a surprising result: the closer quarks are together, the weaker the force - opposite to what is seen with electromagnetism and gravity. Rather, the strong force is analogous to a rubber band stretching, where the force increases as the quarks get farther apart. These physicists discovered this property of quarks, known as asymptotic freedom, in 1976. It later became a key part of the theory of quantum chromodynamics (QCD) and the Standard Model, the current best theory to describe the interac...

    The concept of using amide bond distortion to modulate amidic resonance has been known for more than 75 years. Two classic twisted amides (bridged lactams) ingeniously designed and synthesized by Kirby and Stoltz to feature fully perpendicular amide bonds, and as a consequence emanate amino-ketone-like reactivity, are now routinely recognized in all organic chemistry textbooks. However, only recently the use of amide bond twist (distortion) has advanced to the general organic chemistry mainstream enabling a host of highly attractive N-C amide bond cross-coupling reactions of broad synthetic relevance. In this Minireview, we discuss recent progress in this area and present a detailed overview of the prominent role of amide bond destabilization as a driving force in the development of transition-metal-catalyzed cross-coupling reactions by N-C bond activation. © 2017 Wiley-VCH Verlag GmbH & Co.

    Since 1901 Nobel Prize is awarded for exceptional achievements in physics, chemistry, literature, peace, economy (since 1968) and medicine or physiology. The first aim of the paper is to provide an overview of surgeons - winners of Nobel Prize for medicine or physiology. Although the prominent neurosurgeons were frequently nominated as Nobel Prize candidates, surprisingly no neurosurgeon received this prestigious award so far despite that the results of their research transgressed the relatively narrow limits of neurosurgical speciality.The most prominent leaders in the field of neurosurgery, such as Victor Horsley, Otfrid Foerster, Walter Dandy and Harvey Cushing are discussed from the point of their nominations. The overview of the activity of the Portuguese neurologists and Nobel Prize Winter in 1949 Egas Moniz (occasionally erroneously reported as neurosurgeon) is also provided. Although his work on brain angiography has fundamentally changed the diagnostic possibilities in neurology and neurosurgery, he was eventually awarded Nobel Prize for the introduction of the currently outdated frontal lobotomy.The fact that none of the above mentioned prominent neurosurgeons has not been recognised by Nobel Prize, may be attributed to the fact that their extensive work cannot be captured in a short summary pinpointing its groundbreaking character.

    2013-02-19

    Transition-metal-catalyzed carbene transformations and cross-couplings represent two major reaction types in organometallic chemistry and organic synthesis. However, for a long period of time, these two important areas have evolved separately, with essentially no overlap or integration. Thus, an intriguing question has emerged: can cross-coupling and metal carbene transformations be merged into a single reaction cycle? Such a combination could facilitate the development of novel carbon-carbon bond-forming methodologies. Although this concept was first explored about 10 years ago, rapid developments inthis area have been achieved recently. Palladium catalysts can be used to couple diazo compounds with a wide variety of organic halides. Under oxidative coupling conditions, diazo compounds can also react with arylboronic acids and terminal alkynes. Both of these coupling reactions form carbon-carbon double bonds. As the key step in these catalytic processes, Pd carbene migratory insertion plays a vital role in merging the elementary steps of Pd intermediates, leading to novel carbon-carbon bond formations. Because the diazo substrates can be generated in situ from N-tosylhydrazones in the presence of base, the N-tosylhydrazones can be used as reaction partners, making this type of cross-coupling reaction practical in organic synthesis. N-Tosylhydrazones are easily derived from the corresponding aldehydes or ketones. The Pd-catalyzed cross-coupling of N-tosylhydrazones is considered a complementary reaction to the classic Shapiro reaction for converting carbonyl functionalities into carbon-carbon double bonds. It can also serve as an alternative approach for the Pd-catalyzed cross-coupling of carbonyl compounds, which is usually achieved via triflates. The combination of carbene formation and cross-coupling in a single catalytic cycle is not limited to Pd-catalyzed reactions. Recent studies of Cu-, Rh-, Ni-, and Co-catalyzed cross-coupling reactions with diazo

In his doctoral dissertation he deals with the study of collisions of electrons with molecules of gases. In the physics this experiment is known as 'Franc and Hertz experiment', which confirmed state of energy in Bohr theory and in 1925 he obtained Nobel prize. In 1945, as a director of the Department of physics in the research laboratories of Siemens, he constructed cyclotron kernel - magnet with mass of 80 tonnes. The second Nobel prize winner was Dennis Gabor worked in the Laboratory for measurement and medicinal technology in Siemensstadt (Berlin). When he tried to increase the resolution of electron microscopy he discovered the holography (method of 3-dimensional imaging). In 1971 he obtained the Nobel prize. The third scientist - Ernst Ruska discovered electron microscope. At Siemens, he was involved in developing the first commercially-produced electron microscope in 1939. In 1986, Ernst Ruska was awarded half of the Nobel Prize in Physics for his many achievements in electron optics.

    2017-04-13

    Metal-catalyzed nitrene transfer reactions are an appealing and efficient strategy for accessing tetrasubstituted amines through the direct amination of tertiary C-H bonds. Traditional catalysts for these reactions rely on substrate control to achieve site-selectivity in the C-H amination event; thus, tunability is challenging when competing C-H bonds have similar steric or electronic features. One consequence of this fact is that the impact of catalyst identity on the selectivity in the competitive amination of tertiary C-H bonds has not been well-explored, despite the potential for progress towards predictable and catalyst-controlled C-N bond formation. In this communication, we report investigations into tunable and site-selective nitrene transfers between tertiary C(sp 3 )-H bonds using a combination of transition metal catalysts, including complexes based on Ag, Mn, Rh and Ru. Particularly striking was the ability to reverse the selectivity of nitrene transfer by a simple change in the identity of the N-donor ligand supporting the Ag(i) complex. The combination of our Ag(i) catalysts with known Rh 2 (ii) complexes expands the scope of successful catalyst-controlled intramolecular nitrene transfer and represents a promising springboard for the future development of intermolecular C-H N-group transfer methods.

    A wet-chemical surface texturing technique, including a two-step metal-catalyzed chemical etching (MCCE) and an extra alkaline treatment, has been proven as an efficient way to fabricate high-efficiency black multicrystalline (mc) silicon solar cells, whereas it is limited by the production capacity and the cost cutting due to the complicated process. Here, we demonstrated that with careful control of the composition in etching solution, low-aspect-ratio bowl-like nanostructures with atomically smooth surfaces could be directly achieved by improved one-step MCCE and with no posttreatment, like alkali solution. The doublet surface texture of implementing this nanobowl structure upon the industrialized acidic-textured surface showed concurrent improvement in optical and electrical properties for realizing 18.23% efficiency mc-Si solar cells (156 mm × 156 mm), which is sufficiently higher than 17.7% of the solely acidic-textured cells in the same batch. The one-step MCCE method demonstrated in this study may provide a cost-effective way to manufacture high-performance mc-Si solar cells for the present photovoltaic industry. © 2016 IEEE.

    Full Text Available The metal-catalyzed addition of carboxylic acids to alkynes is a very effective tool for the synthesis of carboxylate-functionalized olefinic compounds in an atom-economical manner. Thus, a large variety of synthetically useful lactones and enol-esters can be accessed through the intra- or intermolecular versions of this process. In order to reduce the environmental impact of these reactions, considerable efforts have been devoted in recent years to the development of catalytic systems able to operate in aqueous media, which represent a real challenge taking into account the tendency of alkynes to undergo hydration in the presence of transition metals. Despite this, different Pd, Pt, Au, Cu and Ru catalysts capable of promoting the intra- and intermolecular addition of carboxylic acids to alkynes in a selective manner in aqueous environments have appeared in the literature. In this review article, an overview of this chemistry is provided. The synthesis of β-oxo esters by catalytic addition of carboxylic acids to terminal propargylic alcohols in water is also discussed.

    The functionalization of C(sp 3 )-H bonds streamlines chemical synthesis by allowing the use of simple molecules and providing novel synthetic disconnections. Intensive recent efforts in the development of new reactions based on C-H functionalization have led to its wider adoption across a range of research areas. This Review discusses the strengths and weaknesses of three main approaches: transition-metal-catalyzed C-H activation, 1,n-hydrogen atom transfer, and transition-metal-catalyzed carbene/nitrene transfer, for the directed functionalization of unactivated C(sp 3 )-H bonds. For each strategy, the scope, the reactivity of different C-H bonds, the position of the reacting C-H bonds relative to the directing group, and stereochemical outcomes are illustrated with examples in the literature. The aim of this Review is to provide guidance for the use of C-H functionalization reactions and inspire future research in this area. © 2018 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.

    One night, Nico invited for dinner all his postdoc and graduate students, in a German restaurant close to Harvard Square. Just before we were to pay for our meal, he told us: "Tomorrow, we shall know the Nobel prize winner. Can you people make a guess on his name?" All my colleagues nominated great physicists. In my turn, I suggested naively (and perhaps nationalistically) the name of Alfred Kastler who had been my thesis adviser. "Come on," joked Nico, "I know a lot of physicists who would deserve it much better.."

    First of all, my thanks to the Nobel Lindau Foundation for their inspiration and leadership in sharing the excitement of scientific discovery with the public and with future scientists! I have had the pleasure of participating twice in the Lindau meetings, and recently worked with the Nobel Labs 360 project to show how we are building the world's greatest telescope yet, the James Webb Space Telescope (JWST). For the future, I see the greatest challenges for all the sciences in continued public outreach and inspiration. Outreach, so the public knows why we are doing what we are doing, and what difference it makes for them today and in the long-term future. Who knows what our destiny may be? It could be glorious, or not, depending on how we all behave. Inspiration, so that the most creative and inquisitive minds can pursue the scientific and engineering discoveries that are at the heart of so much of human prosperity, health, and progress. And, of course, national and local security depend on those discoveries too; scientists have been working with "the government" throughout recorded history. For the Lindau Nobel experiment, we have a truly abundant supply of knowledge and excitement, through the interactions of young scientists with the Nobelists, and through the lectures and the video recordings we can now share with the whole world across the Internet. But the challenge is always to draw attention! With 7 billion inhabitants on Earth, trying to earn a living and have some fun, there are plenty of competing opportunities and demands on us all. So what will draw attention to our efforts at Lindau? These days, word of mouth has become word of (computer) mouse, and ideas propagate as viruses ( or memes) across the Internet according to the interests of the participants. So our challenge is to find and match those interests, so that the efforts of our scientists, photographers, moviemakers, and writers are rewarded by our public. The world changes every day, so there

The new antimicrobials received Nobel prizes until 1960; however no treatment study was awarded the Prize until the discovery of artemisinin and ivermectin, for which the Nobel Prize was awarded in 2015. Collaborative works have increasingly been appreciated. In the future, more female laureates would be expected in the IDR field. Medical graduates and scientists involved in multi-institutional and multidisciplinary collaborative efforts seem to have an advantage.

    2003-09-01

    In 1978, Herbert A. Simon won the Nobel Prize in Economic Sciences, the same Nobel won by Daniel Kahneman in 2002. Simon's work in fact paved the way for Kahneman's Nobel. Although trained in political science and economics rather than psychology, Simon applied psychological ideas to economic theorizing. Classical and neoclassical economic theories assume that people are perfectly rational and strive to optimize economic outcomes. Simon argued that human rationality is constrained, not perfect, and that people seek satisfactory rather than ideal outcomes. Despite his Nobel, Simon felt isolated in economics and ultimately moved into psychology. Nevertheless, his ideas percolated through the economic community, so that Kahneman, whose research advanced Simon's broad perspective, could be the psychologist who won the Nobel in economics.

    Catalysts provide foundational technology for the development of new materials and can enhance the efficiency of routes to known materials. New catalyst technologies offer the possibility of reducing energy and raw material consumption as well as enabling chemical processes with a lower environmental impact. The rising demand and expense of fossil resources has strained national and global economies and has increased the importance of accessing more efficient catalytic processes for the conversion of hydrocarbons to useful products. The goals of the research are to develop and understand single-site homogeneous catalysts for the conversion of readily available hydrocarbons into useful materials. A detailed understanding of these catalytic reactions could lead to the development of catalysts with improved activity, longevity and selectivity. Such transformations could reduce the environmental impact of hydrocarbon functionalization, conserve energy and valuable fossil resources and provide new technologies for the production of liquid fuels. This project is a collaborative effort that incorporates both experimental and computational studies to understand the details of transition metal catalyzed C-H activation and C-C bond forming reactions with olefins. Accomplishments of the current funding period include: (1) We have completed and published studies of C-H activation and catalytic olefin hydroarylation by TpRu{l_brace}P(pyr){sub 3}{r_brace}(NCMe)R (pyr = N-pyrrolyl) complexes. While these systems efficiently initiate stoichiometric benzene C-H activation, catalytic olefin hydroarylation is hindered by inhibition of olefin coordination, which is a result of the steric bulk of the P(pyr){sub 3} ligand. (2) We have extended our studies of catalytic olefin hydroarylation by TpRu(L)(NCMe)Ph systems to L = P(OCH{sub 2}){sub 3}CEt. Thus, we have now completed detailed mechanistic studies of four systems with L = CO, PMe{sub 3}, P(pyr){sub 3} and P(OCH{sub 2}){sub 3}CEt

    2007-01-01

    The 2006 Nobel Prize in Physics was heralded by some in the press as the 'First Nobel Prize for Space Exploration.' Indeed the Nobel Foundation's announcement specifically cited the Cosmic Background Explorer (COBE) satellite launched by NASA in 1989 as the prime-enabling instrument It elaborated further, 'The COBE results provided increased support for the Big Bang scenario for the origin of the Universe... These measurements also marked the inception of cosmology as a precise science.' NASA also seized this unique moment of fame to honor its favorite son, the first Nobel scientist of the agency, John Mather, of the Goddard Space Flight Center, who shared the honor with Professor G. Smoot of the University of California, the Principal Investigator of the COBE measurement. It is without any dispute that the Nobel Prize is the highest scientific honor and best-known award of admiration and inspiration to the public and educational sectors. Unfortunately in the American culture, youths are mostly exposed to success icons in the sports, entertainment, and business domains. Science icons (of either gender) are largely unknown to them. We sincerely hope that success stories of Nobel scientists will become part of the learning curriculum in the K-16 educational experience. In this paper, we examine the pedigree of a number of Nobel Prizes over the years, and discuss their interactions with, and connections to, the space program. It is advantageous for the context of educational and public outreach to see such connections, because in a number of public surveys, one important customer expectation for the space program is the search for new knowledge, to which the Nobel Prize is a prominent benchmark.

    The 2010 Nobel Symposium on Graphene and Quantum Matter, was held at the Grand Hotel in Saltsjöbaden south of Stockholm on 27-31 May. The main theme of the meeting was graphene, and the symposium turned out to be very timely: two of the participants, Andre Geim and Kanstantin Novoselov returned to Stockholm less then six months later to receive the 2010 Nobel Prize in Physics. In these proceedings leading experts give up-to-date, historical, experimental, theoretical and technological perspectives on the remarkable material graphene, and several papers also make connections to other states of quantum matter. Saltsjöbaden is beautifully situated in the inner archipelago of Stockholm. It provided a pleasant setting for the talks and the ensuing discussions that took place in an enthusiastic and friendly atmosphere. The social programme included a boat trip in the light summer night and a dinner at the renowned Grand Hotel. These proceedings are ordered thematically, starting with historical overviews, followed by first experimental and then theoretical papers on the physics of graphene. Next are several papers addressing more general topics in quantum matter and finally contributions on the technological applications of graphene. We hope that this volume will serve as a source of knowledge and inspiration for any physicist interested in graphene, and at the same time provide a snapshot of a young field of research that is developing at very high speed. We are grateful to Marja Fahlander for excellent administrative support, and to the Nobel Foundation who funded the symposium.

    In 1954, John Enders, Thomas Weller, and Frederick Robbins were awarded the Nobel Prize in Physiology or Medicine "for their discovery of the ability of poliomyelitis viruses to grow in cultures of various types of tissue."5370 This discovery provided for the first time opportunities to produce both inactivated and live polio vaccines. By searching previously sealed Nobel Committee archives, we were able to review the deliberations that led to the award. It appears that Sven Gard, who was Professor of Virus Research at the Karolinska Institute and an adjunct member of the Nobel Committee at the time, played a major role in the events leading to the awarding of the Prize. It appears that Gard persuaded the College of Teachers at the Institute to decide not to follow the recommendation by their Nobel Committee to give the Prize to Vincent du Vigneaud. Another peculiar feature of the 1954 Prize is that Weller and Robbins were included based on only two nominations submitted for the first time that year. In his speech at the Nobel Prize ceremony, Gard mentioned the importance of the discovery for the future production of vaccines, but emphasized the implications of this work for growing many different, medically important viruses. We can only speculate on why later nominations highlighting the contributions of scientists such as Jonas Salk, Hilary Koprowski, and Albert Sabin in the development of poliovirus vaccines have not been recognized by a Nobel Prize.

    Alfred Nobel (1833-1896), mainly known for his invention of dynamite and the creation of the Nobel Prices, was an engineer and inventor active in many fields of science and engineering, e.g. chemistry, medicine, mechanics, metallurgy, optics, armoury and rocketry. Amongst his inventions in rocketry was the smokeless solid propellant ballistite (i.e. cordite) patented for the first time in 1887. As a very wealthy person he actively supported many Swedish inventors in their work. One of them was W.T. Unge, who was devoted to the development of rockets and their applications. Nobel and Unge had several rocket patents together and also jointly worked on various rocket applications. In mid-1896 Nobel applied for patents in England and France for "An Improved Mode of Obtaining Photographic Maps and Earth or Ground Measurements" using a photographic camera carried by a "…balloon, rocket or missile…". During the remaining of 1896 the mechanical design of the camera mechanism was pursued and cameras manufactured. In April 1897 (after the death of Alfred Nobel) the first aerial photos were taken by these cameras. These photos might be the first documented aerial photos taken by a rocket borne camera. Cameras and photos from 1897 have been preserved. Nobel did not only develop the rocket borne camera but also proposed methods on how to use the photographs taken for ground measurements and preparing maps.

Using modern plant breeding methods to generate so-called GMOs (Genetically Modified Organisms, agricultural scientists have shown that crop yields and nutritional quality can be greatly improved. Many GMO varieties have been specifically developed with the aim of being resistant to pests, tolerant to drought and containing beneficial nutrients. This leads to a reduction in the use of insecticides in water and on land. If anything, the GMO varieties are safer than traditionally bred varieties because they are made in a very precise manner. However, the scientific evidence on this issue is being ignored by the Green Parties such as Greenpeace who continue to deny the science and mislead the public. 129 Nobel Laureates have joined in a campaign to convince the Green Parties and the public that they should support the use of GMOs, especially for the sake of the developing world.

  16. In the service of peace: 2005 Nobel Peace prize

    International Nuclear Information System (INIS)

    2006-01-01

    Nobel Citation: The Norwegian Nobel Committee has decided that the Nobel Peace Prize for 2005 is to be shared, in two equal parts, between the International Atomic Energy Agency (IAEA) and its Director General, Mohamed ElBaradei, for their efforts to prevent nuclear energy from being used for military purposes and to ensure that nuclear energy for peaceful purposes is used in the safest possible way. At a time when the threat of nuclear arms is again increasing, the Norwegian Nobel Committee wishes to underline that this threat must be met through the broadest possible international cooperation. This principle finds its clearest expression today in the work of the IAEA and its Director General. In the nuclear non-proliferation regime, it is the IAEA which controls that nuclear energy is not misused for military purposes, and the Director General has stood out as an unafraid advocate of new measures to strengthen that regime. At a time when disarmament efforts appear deadlocked, when there is a danger that nuclear arms will spread both to states and to terrorist groups, and when nuclear power again appears to be playing an increasingly significant role, IAEA's work is of incalculable importance. In his will, Alfred Nobel wrote that the Peace Prize should, among other criteria, be awarded to whoever had done most for the abolition or reduction of standing armies. In its application of this criterion in recent decades, the Norwegian Nobel Committee has concentrated on the struggle to diminish the significance of nuclear arms in international politics, with a view to their abolition. That the world has achieved little in this respect makes active opposition to nuclear arms all the more important today. The full Nobel Lecture of the Director General of the IAEA, Mr. Mohamed ElBaradei is given in this paper

    Cycloisomerization of 1,n-enynes and diynes is a powerful method in organic synthesis to access heterocyclic compounds and has drawn increasing attention from organic chemists. In this paper, we attempted to summarize our recent results on the transition metal-catalyzed cycloisomerization to synthesize five or six-membered heterocyclic compounds using 1,n-enynes and diynes having a propargylic ester moiety. First, we will describe the synthesis of 2,3-disubstituted 3-pyrrolines via gold catalyzed cycloisomerization of 1,6-diynes. In addition, we will also disclose a novel silver catalyzed tandem 1,3-acyloxy migration/Mannich-type addition/elimination of the sulfonyl group of N-sulfonylhydrazone-propargylic esters to 5,6-dihydropyridazin-4-one derivatives. Furthermore, we will introduce three interesting examples of the synthesis of bicyclic compounds via titanium or rhodium catalyzed carbocyclization of enynes. In this context, we have presented that 1,n-enynes and diynes containing propargylic esters are highly reactive and useful starting materials for the cycloisomerization catalyzed by a transition metal catalyst.

    This essay describes the ethos (i.e. the character projected to specific audiences) of the 25 Nobel Lectures in Physics, Chemistry, and Physiology or Medicine given in 2013-2015 and the 15 Presentation Speeches given at the Nobel Banquets between 2011 and 2015. A thematically focused qualitative analysis grounded in theories of epideictic discourse indicates the Nobel speakers demonstrated a range of strategies for and degrees of success in negotiating the tensions created by the implicit demands of ceremonial speeches, the scientific emphasis on didactic style and research content, and the different potential audiences (scientific experts and interested publics). Relatively few speeches explicitly displayed goodwill toward humanity instead of primarily toward the scientific community. Some speakers emphasized qualities of goodness in line with social values shared by broad audiences, but some reinforced stereotypes of scientists as anti-social. Speakers were variable in their ability to bridge the substantial gaps in resources for shared good sense.

  13. Alfred Nobel and His Prizes: From Dynamite to DNA.

    Lichtman, Marshall A

    2017-07-01

    Alfred Nobel was one of the most successful chemists, inventors, entrepreneurs, and businessmen of the late nineteenth century. In a decision later in life, he rewrote his will to leave virtually all his fortune to establish prizes for persons of any nationality who made the most compelling achievement for the benefit of mankind in the fields of chemistry, physics, physiology or medicine, literature, and peace among nations. The prizes were first awarded in 1901, five years after his death. In considering his choice of prizes, it may be pertinent that he used the principles of chemistry and physics in his inventions and he had a lifelong devotion to science, he suffered and died from severe coronary and cerebral atherosclerosis, and he was a bibliophile, an author, and mingled with the literati of Paris. His interest in harmony among nations may have derived from the effects of the applications of his inventions in warfare ("merchant of death") and his friendship with a leader in the movement to bring peace to nations of Europe. After some controversy, including Nobel's citizenship, the mechanisms to choose the laureates and make four of the awards were developed by a foundation established in Stockholm; the choice of the laureate for promoting harmony among nations was assigned to the Norwegian Storting, another controversy. The Nobel Prizes after 115 years remain the most prestigious of awards. This review describes the man, his foundation, and the prizes with a special commentary on the Nobel Prize in Physiology or Medicine.

  20. IAEA Nobel Peace fund schools for nutrition. Combating child malnutrition

    International Nuclear Information System (INIS)

    2007-01-01

    Full text: Dhaka, Bangladesh - Malnutrition remains the world's most serious health problem and the single biggest contributor to child deaths in the developing world, according to the World Bank. Now, the International Atomic Energy Agency (IAEA) is using its Nobel Peace Prize earnings to promote the use of nuclear techniques to combat malnutrition during the earliest years of life. 'One out of every ten children born in developing countries will die before his or her fifth birthday,' explains IAEA nutrition expert Lena Davidsson. 'That's more than 10 million dead children each year. And the vast majority of these child deaths in developing countries are preventable with a combination of good care, adequate nutrition and appropriate medical treatment,' explains Dr. Davidsson. 'This brings us hope that unacceptably high childhood mortality can be substantially reduced with effective and well-targeted nutritional interventions.' Undernutrition is an important factor in more than half of all child deaths worldwide. The high prevalence of infants born with low birth weight and undernutrition among Asian children, especially in South Asia, emphasizes the urgent need to develop effective nutrition interventions within 'the window of opportunity', i.e., to target young women before pregnancy as well as infants and young children during the first 2 years of life. The IAEA Nobel Peace Prize Fund School for Nutrition for Asia will be held in Dhaka, Bangladesh, April 22-26, 2007. It will focus on Interventions to combat undernutrition during early life and seeks to disseminate information about the usefulness of stable isotope techniques in intervention programs that reduce malnutrition, in particular in infants and children. The event is hosted by the Government of Bangladesh through the International Centre for Health and Population Research (ICDDR, B) and the Bangladesh Atomic Energy Commission (BAEC). The IAEA is assisting some of the world's poorest countries in their

    The Nobel Prize in Physics for 2008 was awarded to Professors Yoichiro Nambu, Makoto Kobayashi and Toshihide Maskawa. At this opportunity, we held an exhibition to introduce the achievements of the laureates for 10 days at the Omiya campus in May 2009. With the explanations of elementary particle physics, we prepared several experimental instruments with which visitors could play and learn the spontaneous symmetry breaking, cosmic rays, a circle path of an electron in a magnetic field and so on. Our main purpose of the exhibition was, however, not just to explain the contents of the Nobel Prize in Physics, but also to attract students' interests to physics. More than 800 individual students attended during the period, and the survey of questionnaires shows positive contributions to raise the students' awareness of the excitement of physics. (author)

    The Norwegian Nobel Committee awarded the 2005 Nobel Peace Prize to the IAEA and Director General ElBaradei in equal shares. The IAEA and its Director General won the 2005 Peace Prize for their efforts to prevent nuclear energy from being used for military purposes and to ensure that nuclear energy for peaceful purposes is used in the safest possible way. The IAEA Board of Governors subsequently decided that the IAEA's share of the prestigious prize would be used to create a special fund for fellowships and training to improve cancer control and childhood nutrition in the developing world. This fund is known as the 'IAEA Nobel Peace Prize Cancer and Nutrition Fund'. The money will be dedicated to enhancing human resources in developing regions of the world for improved cancer control and childhood nutrition. In the area of cancer control, the money will be spent on establishing regional cancer training institutes for the training of new doctors, medical physicists and technologists in radiation oncology to improve cancer treatment and care, as part of the IAEA's Programme of Action for Cancer Therapy (PACT). In the realm of nutrition, the focus of the Fund will be on capacity building in the use of nuclear techniques to develop interventions to contribute to improved nutrition and health for children in the developing world. Fund-supported fellowship awards will target young professionals, especially women, from Member States, through the IAEA's Technical Cooperation (TC) Programme. Alongside such awards, regional events will be organized in Africa, Asia and Latin America in cancer control and nutrition during 2006. The IAEA Secretariat is encouraging Member States and donors to contribute to the IAEA Nobel Peace Prize Cancer and Nutrition Fund by providing additional resources, in cash and in-kind

  9. Towards Producing Black Nobel Laureates Affiliated with ``African Universities''

    Science.gov (United States)

    Kenneth, Jude

    While Africa has produced a handful Nobel laureate in literature and peace, it has continued to shy away from producing any in the other categories. The reason is not farfetched; our university system is not up to standard. It is saddening that in this century, African countries place emphasis on certificates and not on knowledge. This has made the continent produce students that lack the intellectual capability, experimental ability, fundamental training, creativity, and motivation to excel except they get a foreign training. It is this backdrop that precipitated the research into the methods of teaching and research in universities across Africa. The study is designed to identify the problems and proffer solution to them. Two important questions immediately come to mind. (1) What factors account for the difficulty in producing Nobel laureates affiliated with African universities? (2) What strategies could be adopted to improve teaching and research in African universities? Several factors were investigated which revolve around funding, the competence of the lecturers, quality of students admitted, attitude of the students, parents and government. Nigerian universities were investigated and important deductions were made. During the study an inquiry was made on the method of instruction at various universities, from result obtained, the study therefore concluded that adequate funding, the presence of erudite scholars and brilliant minds will produce future Nobel laureate affiliated with the continent. The study therefore recommended admission and employment of only students and lecturers who have got a thing for academics into the universities and adequate funding of universities and research centres.

    2018-05-01

    The history of the Nobel Prize, since its establishment, interlaces with the history of the public image of science. The aim of this article is to illustrate cinematic scientists, portrayed precisely in their moment of maximum glory. The films and television shows upon which the study is based compose a corpus of 189 media texts. The article identifies three main areas that concern the relation between the Nobel Prize and its audiovisual representations: biopics of real Nobel laureates, the presence of real or fictional Nobel laureates in the film or the show plot, and films and TV series that depict the Nobel ceremony. The article then focuses on four texts that deserve a detailed examination: La fin du monde, The Prize, The Simpsons and The Big Bang Theory. The conclusion compares the representation of the Nobel scientist with general changes in the image of the scientist conveyed by cinema and television.

  11. Global and local "teachable moments": The role of Nobel Prize and national pride.

    2018-05-01

    This study examined to what extent Nobel Prize announcements and awards trigger global and local searches or "teachable moments" related to the laureates and their discoveries. We examined the longitudinal trends in Google searches for the names and discoveries of Nobel laureates from 2012 to 2017. The findings show that Nobel Prize events clearly trigger more searches for laureates, but also for their respective discoveries. We suggest that fascination with the Nobel prize creates a teachable moment not only for the underlying science, but also about the nature of science. Locality also emerged as playing a significant role in intensifying interest.

    We wish to commemorate Paul Ehrlich on the centennial of his being awarded the Nobel Prize in Physiology or Medicine in 1908. His studies are now considered as milestones in immunology: the morphology of leukocytes; his side-chain theory where he defined the cellular receptor for first time; and his clarification of the difference between serum therapy and chemotherapy. Ehrlich also invented the first chemotherapeutic drug: compound 606, or Salvarsan. We have used some original documents from the Royal Society of London, where Ehrlich was a fellow, and from Leipzig University, where he took a degree in medicine.

    2005-03-01

    The public opinion pays much attention to the Nobel Prize as an indicator for the scientific efficiency of a university or a country in connection with foundation of so-called elite universities. The former holder of the psychiatric chair in Jena and discoverer of the electroencephalogram Hans Berger (1873 - 1941) came into discussion as candidate for the Nobel Prize in physiology or medicine. The current medical-historical publications maintain the view that Berger should have received the Nobel Prize in 1936 as well as in 1949. This was prevented in 1936 by an enactment from Hitler, which forbid him to accept the prize, and later in 1949 by Berger's own death. According to documents of the Nobel archives these statements can be disproved. Berger was only nominated three times out of 65 nominations in 1940. Because of his death the other two recommendations in 1942 and 1947 were never evaluated.

    Synthesis of Nobel metal nanoparticles, play a key role in the field of medicine. Plants contain a substantial number of organic constituents, like phenolic compounds and various types of glycosides that help in synthesis of metal nanoparticles. Synthesis of metal nanoparticles by green method is one of the best and environment friendly methods. The major significance of the green synthesis is lack of toxic by-products produced during metal nanoparticle synthesis. The nanoparticles, synthesized by green method show various significant biological activities. Most of the research articles report the synthesized nanoparticles to be active against gram positive and gram negative bacteria. Some of these bacteria include Escherichia coli, Bacillus subtilis, Klebsiella pneumonia and Pseudomonas fluorescens. The synthesized nanoparticles also show significant antifungal activity against Trichophyton simii, Trichophyton mentagrophytes and Trichophyton rubrum as well as different types of cancer cells such as breast cancer cell line.

    The conditions (like very strong magnetic fields, ultralow temperatures, and occurrence of a two-dimensional electron gas in microelectronic structures) for the measurement of the quantum Hall effect are explained. Two possible measuring methods are described. Measuring results for p-Si-MOSFET, GaAs/AlGaAs heterojuntions and grain boundaries in InSb crystals are reported. Differences between normal (integer) and fractional quantum Hall effect are discussed. One of the important consequences is that by means of the quantum Hall effect the value h/e 2 can be determined with very high accuracy. In 1985 Klaus von Klitzing was awarded the Nobel Prize for his work on the quantum Hall effect

Georg Bednorz (second from right) with colleagues from the IBM Zurich Research Laboratory in the LHC tunnel. On their arrival, Jos Engelen, the Chief Scientific Officer, gave the IBM group an introduction to CERN. Bednorz came to CERN only recently for the Open Days to give a seminar, but unfortunately did not have time to visit the experiments, so this trip was organised instead. Along with Alex Müller, Bednorz was awarded the Noble Prize for his discovery of superconductivity for the so-called high temperature superconductors, essentially copper-oxide-based compounds showing superconductivity at temperatures much higher than had previously been thought possible. The LHC magnets are built with low-temperature superconductors but many current leads that supply power to the LHC cryostats are made with...

    Ivan Pavlov (1849-1936) and Santiago Ramón y Cajal (1852-1934) were two contemporary scientists who not only had a great impact on Russian and Spanish science but also on the international stage. Both shared several common features in their life and work, yet they followed fundamentally different paths during their training as scientists. While Pavlov received his laboratory training under the guidance of Ilya Tsion (1843-1912), Cajal did not receive any formal training within a particular laboratory nor did he have a mentor in the traditional sense, rather he was mainly self-taught, although he was supported by key figures like Maestre de San Juan (1828-1890) and Luis Simarro (1851-1921). In this article, we compare the scientific training of these two Nobel Prize laureates and the influences they received during their scientific lives.

    Born in Paris on September 28, 1852, son of an eastern railways' employee and of a dressmaker, Henri Moissan's secondary schooling in Meaux did not allow him to get access to the sesame diploma "baccalauréat" (GCE). In 1869, he did obtain a special certificate of secondary schooling so that he could become an apprentice in watch making. That could have been the end of the story, but dreadful event for France appeared to have beneficial effects for Moissan. Under the threat of the Prussian army, Moissan's family took refuge near Paris. This gave the young Henri the opportunity to register as a student for the second-class pharmacy diploma, which did not need, at the time, the GCE. Moissan became then a trainee in pharmacy in 1871. Meanwhile, he followed the special schooling of "Ecole de chimie" founded by E. Frémy, and then joined the laboratory of Dehérain at the Museum, where he worked in plant physiology. He finally obtained the famous "baccalauréat" (GCE) and could register as a student in first-class pharmacy. He became a pharmacist as well as a doctor in sciences. In 1883, Moissan was named professor at the school of pharmacy in Paris. In 1886, he isolated fluorine by electrolysis of fluorhydric acid, in the presence of potassium fluoride, at a low temperature. He then studied diamond synthesis and gave a start to high temperature chemistry, designing his famous furnace. These findings and many others allowed Moissan to rise to membership in many learned academies around the world. Crowning achievement, Moissan won the Nobel Prize in 1906. A man of culture, collector of autographs and paintings, he died in 1907. Nothing of that would have been possible if there had not been a second-class pharmacist diploma. The history of Henri Moissan is one of a rise from apprenticeship to the Nobel Prize.

  10. INTRODUCTION: Physics of Low-dimensional Systems: Nobel Symposium 73

    Lundqvist, Stig

    1989-01-01

    The physics of low-dimensional systems has developed in a remarkable way over the last decade and has accelerated over the last few years, in particular because of the discovery of the new high temperature superconductors. The new developments started more than fifteen years ago with the discovery of the unexpected quasi-one-dimensional character of the TTF-TCNQ. Since then the field of conducting quasi-one-dimensional organic systems have been rapidly growing. Parallel to the experimental work there has been an important theoretical development of great conceptual importance, such as charge density waves, soliton-like excitations, fractional charges, new symmetry properties etc. A new field of fundamental importance was the discovery of the Quantum Hall Effect in 1980. This field is still expanding with new experimental and theoretical discoveries. In 1986, then, came the totally unexpected discovery of high temperature superconductivity which started an explosive development. The three areas just mentioned formed the main themes of the Symposium. They do not in any way exhaust the progress in low-dimensional physics. We should mention the recent important development with both two-dimensional and one-dimensional and even zero-dimensional structures (quantum dots). The physics of mesoscopic systems is another important area where the low dimensionality is a key feature. Because of the small format of this Symposium we could unfortunately not cover these areas. A Nobel Symposium provides an excellent opportunity to bring together a group of prominent scientists for a stimulating exchange of new ideas and results. The Nobel Symposia are very small meetings by invitation only and the number of key international participants is typically in the range 25-40. These Symposia are arranged through a special Nobel Symposium Committee after proposal from individuals. This Symposium was sponsored by the Nobel Foundation through its Nobel Symposium Fund with grants from The

    Funding is important for scientists' work and may contribute to exceptional research outcomes. We analyzed the funding sources reported in the landmark scientific papers of Nobel Prize winners. Between 2000 and 2008, 70 Nobel laureates won recognition in medicine, physics, and chemistry. Sixty five (70%) of the 93 selected papers related to the Nobel-awarded work reported some funding source including U.S. government sources in 53 (82%), non-U.S. government sources in 19 (29%), and nongovernment sources in 33 (51%). A substantial portion of this exceptional work was unfunded. We contacted Nobel laureates whose landmark papers reported no funding. Thirteen Nobel laureates responded and offered their insights about the funding process and difficulties inherent in funding. Overall, very diverse sources amounting to a total of 64 different listed sponsors supported Nobel-related work. A few public institutions, in particular the U.S. National Institutes of Health (with n=26 funded papers) and the National Science Foundation (with n=17 papers), stood out for their successful record for funding exceptional research. However, Nobel-level work arose even from completely unfunded research, especially when institutions offered a protected environment for dedicated scientists.

    The Nobel Prize was established by Alfred Nobel in 1901 to award people who have made outstanding achievements in physics, chemistry and medicine. So far, from 852 laureates, 45 have been female. Marie Curie was the first woman to receive the Nobel Prize in 1903 for physics and eight years later also for chemistry It is remarkable that her daughter Irene and her husband also received the Nobel Prize for chemistry in 1935. Other two married couples, Cori and Moser, have also been awarded the Nobel Prize. The present commentary attempts to show the female participation in the progress of scientific activities.

  13. Another Nobel Prize linked to synchrotron radiation work

    The 2008 Nobel Prize in Chemistry went to Osamu Shimomura, Martin Chalfie and Roger Tsien 'for the discovery and development of the green fluorescent protein, GFP'. This year's Nobel Prize in Chemistry rewards the initial discovery of GFP and a series of important developments which have led to its use as a tagging tool in bioscience. By using DNA technology, researchers can now connect GFP to other interesting, but otherwise invisible, proteins. This glowing marker allows the movements, positions and interactions of the tagged proteins to be monitored. Osamu Shimomura was the first to isolate GFP from the jellyfish Aequorea victoria, found off the west coast of North America, and discovered the protein's green glow (Shimomura et al. (1962). J. Cell. Comp. Physiol. 59, 223-240). Martin Chalfie demonstrated the value of GFP as a luminous genetic tag. In one of his first experiments he coloured six individual cells in the transparent roundworm Caenorhabditis elegans with the aid of GFP. He had obtained the GFP gene (gfp) clone from Prasher (Prasher et al. (1992). Gene, 111, 229-233) and expressed it in E. coli. The GFP protein displayed a bright green fluorescence in this heterologous organism, suggesting that it could indeed serve as a versatile genetic marker in virtually all organisms. Chalfie transformed C. elegans with gfp under the control of a promoter regulating the expression of β-tubulin, abundant in six touch receptor neurons in C. elegans. The organism subsequently expressed GFP from distinct positions in its body and at distinct times in its development (Chalfie et al. (1994). Science, 263, 802-805). Roger Tsien contributed to the general understanding of how GFP glows by determining the formation of the GFP chromophore, a chemical group that absorbs and emits light. Tsien is best known for extending the colour palette of GFP beyond green, allowing researchers to follow several different biological processes at the same time. According to background on

    2009-12-09

    Peter Agre, born in 1949 in Northfield Minnesota, shared the 2003 Nobel Prize in Chemistry with Roderick MacKinnon for his discovery of aquaporins, the channel proteins that allow water to cross the cell membrane. Agre's interest medicine was inspired by the humanitarian efforts of the Medical Missionary program run by the Norwegians of his home community in Minnesota. Hoping to provide new treatments for diseases affecting the poor, he joined a cholera laboratory during medical school at Johns Hopkins. He found that he enjoyed biomedical research, and continued his laboratory studies for an additional year after medical school. Agre completed his clinical training at Case Western Hospitals of Cleveland and the University of North Carolina, and returned to Johns Hopkins in 1981. There, his serendipitous discovery of aquaporins was made while pursuing the identity of the Rhesus (Rh) antigen. For a century, physiologists and biophysicists had been trying to understand the mechanism by which fluid passed across the cell's plasma membrane. Biophysical evidence indicated a limit to passive diffusion of water, suggesting the existence of another mechanism for water transport across the membrane. The putative "water channel," however, could not be identified. In 1988, while attempting to purify the 30 kDa Rh protein, Agre and colleagues began investigating a 28 kDa contaminant that they believed to be a proteolytic fragment of the Rh protein. Subsequent studies over the next 3-4 years revealed that the contaminant was a membrane-spanning oligomeric protein, unrelated to the Rh antigen, and that it was highly abundant in renal tubules and red blood cells. Still, they could not assign a function to it. The breakthrough came following a visit with his friend and former mentor John Parker. After Agre described the properties of the mysterious 28 kDa protein, Parker suggested that it might be the long-sought-after water channel. Agre and colleagues tested this idea by

    To fight the looming cancer crisis in Africa, the International Atomic Energy Agency (IAEA) is assembling many of the world's leading cancer experts in Cape Town on 11-16 December. Cancer is a disease that is spreading very fast in the developing world and the IAEA has come to realize that we need to do much more to combat cancer in this part of the world, says IAEA Director General Mohamed ElBaradei in a video address to the conference. I hope this event will be the first of many events that would enable us to work together - national governments, international organisations, civil society - to help combat this dreadful disease and provide quality of life to our fellow human beings. With the support of African Nobel Laureates Nelson Mandela, Archbishop Desmond Tutu and F.W. de Klerk, this unprecedented gathering will bring together senior representatives from major national and international cancer organisations. Together with leading public figures and specialists they will assess the growing cancer burden in Africa and focus on building effective cancer control programmes at the national and regional levels. The IAEA is sponsoring the intensive workshops using funds awarded for the 2005 Nobel Peace Prize. The IAEA's Programme of Action for Cancer Therapy, or 'PACT', was established in 2004 to help achieve these goals. Building on the IAEA's 30 years of expertise in promoting radiotherapy, PACT aims to help get more cancer treatment facilities up and running in the world's developing regions, along with the trained personnel to operate them. 'PACT' is building partnerships with the WHO and other international cancer-control organisations so that the battle against cancer can be waged at country level. This includes cancer prevention, early detection, diagnosis and palliation, and more importantly education and training of professionals, says PACT Head Massoud Samiei. Current estimates suggest that several billion US$ are needed in the next 10 to 15 years if the

Shiller, however, determined that, although it is almost impossible to predict the stock prices for a period of few days, this is not true for a period of several years. He discovered that the stock prices fluctuate much more substantially than corporation dividents, and that the relationship between prices and dividends tends to decline when high, and to grow when low. This pattern does not apply only to stocks, but also to bonds and other forms of capital.

This awarding to a group of scientists may look surprising. However, it just reflects the fear that climatic change represents a threat for the international safety. It shows that any mastering action of this global warming involves a very strategical sector, the energy sector, and disturbs our ways of producing, of consuming and of transporting ourselves. It is of prime importance to maintain the dialogue between the supporters of the two opposite visions of the world with contradictory interests, since the climate topic is a strong source of potential conflicts. This is one of the missions of the IPCC, a group of experts elected by their peers to establish a state-of-the-art of the scientific knowledge about climate change.

    correction, have yet to be solved. It has been predicted that quantum computers will be able to perform certain complicated computations or simulations in minutes or hours instead of years as with present computers. So far there exist very few useful quantum algorithms; however there is hope that the development of these will be stimulated once there is a breakthrough in hardware. Remarkable progress has been made in quantum engineering and quantum measurements, but a large scale quantum computer is still far off. Quantum communication and cryptography are much closer to the market than a quantum computer. The development of quantum information has meant a large push in the field of quantum physics, that previously could only be studied in the microscopic world. Artificial atoms, realized by circuit technology and mimicking the properties of 'natural' atoms, are one example of the new possibilities opened up by quantum engineering. Several different types of qubits have been suggested. Some are based upon microscopic entities, like atoms and ions in traps, or nuclear spins in molecules. They can have long coherence times (i.e. a long period allowing many operations, of the order of 10 000, to be performed before the state needs to be refreshed) but they are difficult to integrate into large systems. Other qubits are based upon solid state components that facilitate integration and coupling between qubits, but they suffer from interactions with the environment and their coherent states have a limited lifetime. Advanced experiments have been performed with superconducting Josephson junctions and many breakthroughs have been reported in the last few years. They have an advantage in the inherent coherence of superconducting Cooper pairs over macroscopic distances. We chose to focus the Nobel Symposium on Qubits for Future Quantum Information on superconducting qubits to allow for depth in discussions, but at the same time to allow comparison with other types of qubits that may

    The Nobel Prize in Physiology or Medecine 2011 was awarded to Ralph M. Steinman, Jules A. Hoffman and Bruce A. Beutler for the discovery of essential elements of innate immunity, in particular dendritic cells (DCs) and toll-like receptors (TLRs). Antigens become immunogenic and capable of triggering an adaptive immune response involving antigen-specific, MHC- restricted effector T cells, only if they are captured and presented by “accessory” cells. In 1972, Ralph M. Steinman and Zanvil Cohn identified in lymphoid tissues, cells with treelike, arborescent morphology that they named “dendritic cells” (DC) (from the greek word “tree” for tree, δένδρον) with a superior ability to induce alloreactive T cell proliferation in vitro (1978) and to stimulate the rejection of kidney allotransplants in rodents (1982). Thirty years after their discovery, DCare now known to play a seminal role in bridging innate and adaptive immunity, In addition DC are being used in numerous clinical studies all over the world to increase immunity to infectious or tumor-associated antigens. This effort involved the contribution of an international network of basicand clinical scientists spearheaded by Ralph M. Steinman to defineappropriate culture conditions to generate ex vivo DC from circulating or bone marrow precursors, to definefunctionally distinct DC subsets, to identifytheir maturation pathways including those relying on the stimulation of TLRs, and finally to develop DC based-vaccines to immunize patients infected with HIV or affected by cancer. Here, we will detail the history of DC and outline the therapeutic implications of Ralph M. Steinman’s seminal discovery.

The Nobel Prize is today widely considered as the most prestigious international symbol of scientific excellence, but it still is an exciting research question how it gained such prestige. Drawing on files from the Emil von Behring Archive in Marburg, Germany, and the Archive of the Nobel Assembly for Physiology or Medicine in Stockholm this essay aims at shedding light on why the first Nobel Prize for Physiology or Medicine in 1901 was awarded the German immunologist Emil von Behring, and how this decision was viewed at that time. This study is part of a research project that explores mechanisms leading to scientific recognition by using the example of the Nobel Prize for Physiology or Medicine. © Georg Thieme Verlag KG Stuttgart · New York.

  12. Translation, Littérisation, and the Nobel Prize for Literature

    Full Text Available This work is a cultural economics study of the problem of translation production and assessment in and leading up to the literary Nobel Prize deliberations. I argue that the constraints of assessing an unevenly and partially translated body of literary works, many of them from less common languages, present an unbreachable expertise gap. Translation as a sacralization, or consecration in Casanova’s (2004 term, of a writer’s work is considered in the context of the award. Ultimately the prize is shown to depend upon translations carried out in dissimilar circumstances for each candidate. The award of the Nobel is part of the founder’s call for works to be more widely circulated, not to reward fame; thus a Nobel is more an invitation to translate than a recognition of an author in translation, although evidence suggests that the post-Nobel translational impact may vary by writer and over time. This study sheds light on the degree to which the Prize is an authority-mediated phenomenon, and while critiquing the quixotic task of judging disparate forms and amounts of cultural capital side by side, and never from a point of neutrality, it also attempts to show how translation shapes this symbolic form of prestige in the struggle for existence. I posit that alternative prizes and prize-awarding in general as fraught with similar cross-language challenges. Possibilities for future research, qualitative analysis of the Nobel and translation demand, among other consequences, are briefly sketched.

    Full Text Available Since the start in 1901, with the exception of the war years, the Nobel Prizes have always been awarded on the 10th of December, to mark the day of Alfred Nobel's demise. The exception is the prize for achievements in economic sciences which only started to be awarded in 1969. Since 1995 the Prize in Economic Sciences has been defined as the Prize in Social Sciences, so that the other recognized scientists in these fields, such as political sciences, psychology and sociology, could be awarded. Moreover, it was established that the Prize can be divided among no more than three winners. The Prize in Economic Sciences has been awarded to the total of 76 scientists, most of which, i.e. 52 of them, were the citizens of the USA. The largest number of laureates, i.e. twelve, came from the University of Chicago, six of them from Princeton, and five from Berkley. It was only once, in 2009, that the Nobel Prize in Economics was awarded to a woman - Elinor Ostrom (1933-2012 from the USA, together with Oliver Williamson. The average age of the Nobel Prize winners is about 60 years. The oldest laureate to have ever won the prize was Leonid Hurwicz, who received the Nobel Prize in Economic Sciences in 2007 at the age of 90.

  14. The legislative actor in the Nobel era: Quo Vadis EU?

    Full Text Available The idea of a political union, as well as an economic union of Europe, beyond free circulation of persons, goods and services, has always been included in the ideals of the building of Europe. However, its de jure formalization only occurs on November 1, 1993, when the Treaty of Maastricht is in force and a new political and strategic actor is in place: the European Union (EU. Since then, literature has "defined" the European Union in order to clearly establish what this UPO - Unidentified Political Object (an expression by Jacques Delors in the 1990s - is or what it can be. One of the ideas which has been a focus of discussion is that of "legislative actor" (Manners, 2001; 2002, which claims that the European Union has progressed towards normativity, both internally as well as externally, to its close neighbors and its relations with the rest of the world. This paper aims to contribute to the discussion on Europe's quality or condition to impose rules. We will begin by systematizing a series of achievements which, according to Manners, lead to the triangle democracy, Human Rights and good governance in the signing of the Treaty of Lisbon on December 13, 2007 and its entering in full force on December 1, 2009. However, this paper does not disregard the fact that the concept "legislative actor" has been (reworked and perfected by its author and other scholars due to criticism and empirical studies and has thus been altered, enhanced and argued against. Therefore, some concepts will be studied whose arguments will allow us to question the internal and external dimension of the actor European Union. We will also explore the symbolic power of the Union in the development of tools and capacity to be acknowledged as an actor able to face current threats and challenges but whose profile may not be different from other actors in international relations. Finally, we will discuss the impact of the EU having been awarded the Nobel Peace Prize in 2012 on

  15. The laureate as celebrity genius: How Scientific American's John Horgan profiled Nobel Prize winners.

    Fahy, Declan

    2018-05-01

    When scientists become Nobel laureates, they become famous in science and public life, but few studies have examined the nature of their scientific celebrity. This article examines how Scientific American portrayed laureates in order to identify and explain core features of Nobel fame. It examines the portrayals of seven laureates - Francis Crick, Linus Pauling, Hans Bethe, Murray Gell-Mann, Brian Josephson, Philip Anderson and Subrahmanyan Chandrasekhar - in magazine profiles written between 1992 and 1995 by science writer John Horgan. Its textual analysis finds the scientists are portrayed as combining the sociological characteristics of genius, including enormous productivity and lasting impact, with the representational characteristics of celebrities, such as the merging of public and private lives. Their form of scientific celebrity is grounded in their field-changing research, which is presented as a product of their idiosyncratic personalities. Nobel science is presented as knowledge created by an ultra-elite of exceptional individuals.

    Full text: More than 60 of the world's leading cancer experts are being brought together in Buenos Aires, 23-27 April 2007, by the International Atomic Energy Agency (IAEA) to assess Latin America's growing cancer burden. Poor medical facilities and lack of trained personnel and funding are limiting countries' ability to expand cancer care services and treat patients, while cancer rates are expected to double by 2020. More than 70 per cent of all cancer deaths occur in low and middle income countries and globally cancer kills more people than AIDS, malaria and tuberculosis combined. Through its Programme of Action for Cancer Therapy (PACT) the IAEA is using funds, awarded for the 2005 Nobel Peace Prize, to sponsor training workshops, such as the Buenos Aires event, that alert policy makers and health experts to the pressing need for national cancer control plans and programmes. 'I hope that this event in Latin America is the first of many that will enable us to work together to help combat this dreadful disease and provide quality of life to our fellow human beings,' said Director General of the IAEA, Dr. Mohamed ElBaradei. 'Cancer is a disease that is spreading very fast in the developing world and we have come to realise that we have to do much more to combat it in this part of the world.' In Latin America, there are an estimated 450,000 cancer deaths annually. The most commonly occurring cancers in men are prostate, stomach, lung, and colorectal and in women the most commonly occurring cancers are breast, cervix, stomach and colorectal. Breast and cervical cancer can be prevented through screening and early detection and can be cured in the early stages with effective treatment. The World Health Organization (WHO) warns that cancer will soon reach epidemic proportions, causing up to 10 million deaths a year by 2020. Yet at least one third of all cancers are preventable.

    The aldol reaction is one of the most powerful and versatile methods for the construction of C-C bonds. Traditionally, this reaction was developed in a stoichiometric version; however, great efforts in the development of chiral catalysts for aldol reactions were performed in recent years. Thus, in this review article, the development of metal-mediated chiral catalysts in Mukaiyama-type aldol reaction, reductive aldol reaction and direct aldol reaction are discussed. Moreover, the application of these catalysts in the total synthesis of complex molecules is discussed. (author)

    Full Text Available Although there is a broad agreement among scientists and science educators that students should not only learn science, but also acquire some sense of its nature, it has been reported that undergraduate students possess an inadequate grasp of the nature of science (NOS. The study presented here examined the potential and effectiveness of Nobel Prize stories as a vehicle for teaching NOS. For this purpose, a 36-hour course, “Albert Einstein’s Nobel Prize and the Nature of Science,” was developed and conducted in Taiwan Normal University. Ten undergraduate physics students participated in the course. Analysis of the Views of Nature of Science questionnaires completed by the students before and after the course, as well as the students’ own presentations of Nobel Prize stories (with an emphasis on how NOS characteristics are reflected in the story, showed that the students who participated in the course enriched their views concerning all aspects of NOS. The paper concludes with some suggestions for applying the novel idea of using Nobel Prize stories in physics classrooms.

    American Biologist Martin Chalfie shared the 2008 Nobel Prize in Chemistry with Roger Tsien and Osamu Shimomura for their discovery and development of the Green Fluorescent Protein (GFP). Martin Chalfie was born in Chicago in 1947 and grew up in Skokie Illinois. Although he had an interest in science from a young age--learning the names of the planets and reading books about dinosaurs--his journey to a career in biological science was circuitous. In high school, Chalfie enjoyed his AP Chemistry course, but his other science courses did not make much of an impression on him, and he began his undergraduate studies at Harvard uncertain of what he wanted to study. Eventually he did choose to major in Biochemistry, and during the summer between his sophomore and junior years, he joined Klaus Weber's lab and began his first real research project, studying the active site of the enzyme aspartate transcarbamylase. Unfortunately, none of the experiments he performed in Weber's lab worked, and Chalfie came to the conclusion that research was not for him. Following graduation in 1969, he was hired as a teacher Hamden Hall Country Day School in Connecticut where he taught high school chemistry, algebra, and social sciences for 2 years. After his first year of teaching, he decided to give research another try. He took a summer job in Jose Zadunaisky's lab at Yale, studying chloride transport in the frog retina. Chalfie enjoyed this experience a great deal, and having gained confidence in his own scientific abilities, he applied to graduate school at Harvard, where he joined the Physiology department in 1972 and studied norepinephrine synthesis and secretion under Bob Pearlman. His interest in working on C. elegans led him to post doc with Sydney Brenner, at the Medical Research Council Laboratory of Molecular Biology in Cambridge, England. In 1982 he was offered position at Columbia University. When Chalfie first heard about GFP at a research seminar given by Paul Brehm in 1989

    ElBaradei, M.

    2005-01-01

    On the occasion of receiving the Nobel Price the Director General of the International Atomic Energy Agency, Dr. Mohamed ElBaradei expressed his feeling of gratitude, pride and hope. He stated that with this recognition, the Norwegian Nobel Committee underscores the value and the relevance of the work the IAEA has been doing. It recognizes the urgency of addressing the dangers we face: nuclear proliferation, nuclear armaments, and nuclear terrorism. The award will lend prominence and impetus to the IAEA's ultimate objective - of passing to our children a world free of nuclear weapons - and for that I am deeply grateful. He takes great pride in all the men and women who serve at the International Atomic Energy Agency. The IAEA was founded with a simple credo: 'Atoms for Peace' - meaning that nuclear science should be used safely and securely in the service of humankind - in peaceful applications related to energy production, health, water, agriculture and other aspects of development -- and not for its destruction. More than anything, this award suggests that, almost five decades later, we are still focused unwaveringly on living up to that objective. He believes that the road to international peace and security lies through multilateralism - the collective search by people of all racial, religious, ethnic and national backgrounds to find a common ground, based not on intimidation or rivalry but on understanding and human solidarity. In a practical sense, this means developing a functional system of international security that does not derive from a nuclear weapons deterrent - but rather based on addressing the security concerns of all. The fact that the IAEA was awarded the Nobel Peace Prize gives renewed hope that, working in concert, the international community can achieve this goal. It strengthens both aspects of the Agency's mandate: ensuring that the benefits of nuclear energy are distributed as broadly as possible in the service of humankind, and working

    2011-01-01

    The 2010 Nobel Prize in physics was awarded to Professors Andre Geim and Konstantin Novoselov for their ground-breaking experiments on graphene, a single atomic layer of carbon, and more generally, for their pioneering work in uncovering a new class of materials, namely two-dimensional atomic crystals. This paper gives an accessible account and review of the story of graphene; from its first description in the literature, to the realization and confirmation of its remarkable properties, through to its impressive potential for broad-reaching applications. The story of graphene is written within the context of the enormous impact that Geim and Novoselovs' work has had on this field of research, and recounts their personal pathways of discovery, which ultimately led to their award of the 2010 Nobel Prize.

    2007-01-01

    I will describe the history of the universe, from the Big Bang to 2013, when the JWST is to be launched to look back towards our beginnings. I will discuss how the COBE results led to the Nobel Prize, how the COBE results have been confirmed and extended, and their implications for future observations. The James Webb Space Telescope will be used to examine every part of our history from the first stars and galaxies to the formation of individual stars and planets and the delivery of life-supporting materials to the Earth. I will describe the plans for the JWST and how observers may use it. With luck, the JWST may produce a Nobel Prize for some discovery we can only guess today.

    2014-01-01

    The archive of the Nobel Assembly for Physiology or Medicine in Solna, Sweden, is a remarkable repository that contains reports and dossiers of the Nobel Prize nominations of senior and junior physicians from around the world. Although this archive has begun to be used more by scholars, it has been insufficiently examined by historians of surgery. No other German surgeon was nominated as often as Ferdinand Sauerbruch for the Nobel Prize for Physiology or Medicine in the first half of the 20th century. This contribution reconstructs why and by whom Sauerbruch was nominated, and discusses the Nobel committee evaluations of his work. Political factors did not play an obvious role in the Nobel committee discussions, in spite of the fact that Adolf Hitler in 1937 had prohibited all German citizens to accept the Nobel Prize. The main reasons why Sauerbruch ultimately was not considered prize- worthy were that Sauerbruch's achievements were marked by scientific priority disputes, and that his work was not seen as original enough.

    2013-01-01

    Displays the life and work of 10 Nobel laureates. Presents interesting background information on how great science is achieved. Presents the history of superconductivity through 100 years of progress. 10 great scientists tell their unique stories in their own words. Personal stories of Bednorz, Mueller and 8 other Nobel laureates. This book is about the work of 10 great scientists; who they were and are, their personal background and how they achieved their outstanding results and took their prominent place in science history. We follow one of physics and science history's most enigmatic phenomena, superconductivity, through 100 years, from its discovery in 1911 to the present, not as a history book in the usual sense, but through close ups of the leading characters and their role in that story, the Nobel laureates, who were still among us in the years 2001-2004 when the main round of interviews was carried out. Since then two of them already passed away. For each one of the 10 laureates, the author tells their story by direct quotation from interviews in their own words. Each chapter treats one laureate. The author first gives a brief account of the laureates' scientific background and main contribution. Then each laureate tells his own story in his own words. This book is unique in its approach to science history.

  18. The 2008 Lindau Nobel Laureate Meeting: Robert Huber, Chemistry 1988. Interview by Klaus J. Korak.

    Science.gov (United States)

    Huber, Robert

    2008-11-25

    Robert Huber and his colleagues, Johann Deisenhofer and Hartmut Michel, elucidated the three-dimensional structure of the Rhodopseudomonas viridis photosynthetic reaction center. This membrane protein complex is a basic component of photosynthesis - a process fundamental to life on Earth - and for their work, Huber and his colleagues received the 1988 Nobel Prize in Chemistry. Because structural information is central to understanding virtually any biological process, Huber likens their discovery to "switching on the light" for scientists trying to understand photosynthesis. Huber marvels at the growth of structural biology since the time he entered the field, when crystallographers worked with hand-made instruments and primitive computers, and only "a handful" of crystallographers would meet annually in the Bavarian Alps. In the "explosion" of structural biology since his early days of research, Huber looks to the rising generation of scientists to solve the remaining mysteries in the field - such as the mechanisms that underlie protein folding. A strong proponent of science mentorship, Huber delights in meeting young researchers at the annual Nobel Laureate Meetings in Lindau, Germany. He hopes that among these young scientists is an "Einstein of biology" who, he says with a twinkle in his eye, "doesn't know it yet." The interview was conducted by JoVE co-founder Klaus J. Korak at the Lindau Nobel Laureate Meeting 2008 in Lindau, Germany.

    Full Text Available Nobel Laureates with their contributions to the development of the theory of general equilibrium have enabled this theory to be one of the most important for theoretical and practical analysis of the overall economy and the efficient use of economic resources. Results of the research showing that contributions of Nobel Laureates in the economy belong to two main frameworks of development of the general equilibrium theory: one was the mathematical model of general equilibrium developed by John R. Hicks (1939, Kenneth J.Arrow (1951 and Gerard Debreu (1954 and second frames of general equilibrium belongs to Paul A. Samuelson (1958. To highlight the contributions of these Nobel laureates in the development of the theory of general equilibrium have been selected and are presented in the paper some views, estimates and assumptions that have contributed not only in solving concrete problems, but also to the development of economic science in general. Their works represent a synthesis of theoretical and practical aspects of treatment of general equilibrium which are the starting point for further research in this field.

    Thompson, Sarah M

    2008-01-01

    One hundred and one years after J J Thomson was awarded the Nobel Prize for the discovery of the electron, the 2007 Nobel Prize for Physics was awarded to Professors Peter Gruenberg and Albert Fert for the discovery of giant magnetoresistance (GMR) in which the spin as well as the charge of the electron is manipulated and exploited in nanoscale magnetic materials. The journey to GMR started with Lord Kelvin who 150 years ago in 1857 made the first observations of anisotropic magnetoresistance and includes Sir Neville Mott who in 1936 realized that electric current in metals could be considered as two independent spin channels. Modern technology also has a significant role to play in the award of this Nobel Prize: GMR is only manifest in nanoscale materials, and the development of nanotechnology growth techniques was a necessary pre-requisite; further, the considerable demands of the magnetic data storage industry to drive up the data density stored on a hard disk fuelled an enormous international research effort following the initial discovery with the result that more than 5 billion GMR read heads have been manufactured since 1997, ubiquitous in hard disks today. This technology drive continues to inspire exploration of the spin current in the field now known as spintronics, generating new ideas and applications. This review explores the science underpinning GMR and spintronics, the different routes to its discovery taken by Professors Gruenberg and Fert, the new science, materials and applications that the discovery has triggered and the considerable potential for the future.

  3. Reflections on the Cultural Background to China's Reaction to the Nobel Prize Award

    Directory of Open Access Journals (Sweden)

    Gunnar Haaland

    2012-06-01

    Full Text Available This paper deals with some complex and controversial issues that arose in connection with the 2010 Nobel Prize Peace award to the Chinese dissident Liu Xiao Bo. These issues involve different levels. On one level it is important not to confuse the Nobel committee’s independence of outside interference from political and other organized agencies, with the question of whether the Nobel Prize committee’s decisions can be ideological or politically unbiased in its decisions. Part of the strong Chinese reaction to the award is related to this issue. Another level deals with the Committee’s widening of the criteria to be taken into account in the selection of candidates from the original criterion focused on direct contribution to reduction of armed conflicts, to the wider issues of indirect contributions like alleviation of poverty, ecological sustainability and most crucial the issue of human rights. The last issue is particularly critical since different states have different perspectives of what constitute human rights, and what rights should be given priority on different levels of the country’s development. The main point of the article is to look at historical events and socio-cultural conditions that shape the Chine Government’s (and many citizens’ reaction to the 2010 award. This is placed in the context of the widening income differences emerging in the modern political economy of China and how these may affect the growth of civil society. The critical question is: will the reward contribute to promotion of civil society or will it lead to increased crackdown on dissident voices.

    2018-05-01

    Between 1962 and 2004, Nobel Prize laureates appear in the British television science programme Horizon in various roles, denoting differing understandings of science in relation to society and culture. These representations are the outcome of an interplay of cultural and institutional factors. They vary with the broadcasting environment. Notably, the article establishes that the choice of presenting scientists as heroic characters in strongly determined storylines from the late-1990s onwards originates in a reaction to institutional imperatives as a means to preserve the existence of the Horizon series. The article shows that exigencies of the institutional context in which media professionals operate are major factors influencing the representation of science in public.

    The history of the discovery and development of streptomycin is reviewed here from the personal standpoint of a member of Dr. Selman Waksman's antibiotic screening research team. The team approach of eight individuals illustrates how the gradual enhancement of the screening methodology was developed. I illustrate three study periods with key aspects in the development of streptomycin which led to a Nobel Prize being granted to Professor Waksman. One item not previously emphasized is the employment of a submerged culture technique for large-scale production of streptomycin, thus enabling rapid animal testing and human clinical trials with Mycobacterium tuberculosis. Another is that purified streptomycin was shown by Dr. Waksman to be distinctly different from the substances called natural products, which are no longer patentable in the United States; therefore, streptomycin was found to be patentable. A third item not previously emphasized is his emphasis on the screening of actinomycetes, including the newly named Streptomyces genus. All of these factors contributed to the success of streptomycin in the treatment of tuberculosis. In combination, their successes led to Dr. Waksman's department becoming a new pharmacological research area, specializing in drug discovery. These unique accomplishments all burnish the prior rationales used by the Karolinska Institute in granting Dr. Waksman alone the 1952 Nobel Prize for Physiology or Medicine.

    Fouquerel, Elise; Opresko, Patricia L

    2017-01-01

    The fields of telomere biology and DNA repair have enjoyed a great deal of cross-fertilization and convergence in recent years. Telomeres function at chromosome ends to prevent them from being falsely recognized as chromosome breaks by the DNA damage response and repair machineries. Conversely, both canonical and nonconical functions of numerous DNA repair proteins have been found to be critical for preserving telomere structure and function. In 2009, Elizabeth Blackburn, Carol Greider and Jack Szostak were awarded the Nobel prize in Physiology or Medicine for the discovery of telomeres and telomerase. Four years later, pioneers in the field of DNA repair, Aziz Sancar, Tomas Lindahl and Paul Modrich were recognized for their seminal contributions by being awarded the Nobel Prize in Chemistry. This review is part of a special issue meant to celebrate this amazing achievement, and will focus in particular on the convergence of nucleotide excision repair and telomere biology, and will discuss the profound implications for human health. © 2016 The American Society of Photobiology.

    Full Text Available Today we are in a global economic crisis. It is not an economic crisis because of scale, for the worst case there was a recession of a few percent of GDP, but rather because it was consistently induced. The best strategies have been proposed so far are essentially neo-Keynesian, as private demand fell, public expenditure can change aggregate demand to provide a stimulus to the economy. At best, this can provide the necessary infrastructure for positive externalities through network effects, at worst, will only serve as a delay tactic, leading to a greater crisis in the near future. Nobel prizes were created by scientist and businessman Alfred Nobel (1833 - 1896, inventor (1867, which, in his will asked that his immense wealth income are offered each year „awards as the which, in the previous year, brought the greatest service of humanity”. Thus, by the will left by Alfred Nobel, Nobel prizes are awarded to institutions: - Swedish Royal Academy of Science: Nobel Prize in Physics, Chemistry Nobel Prize Nobel Prize in Economics; - Carolina Institute in Stockholm: Nobel Prize for Medicine; - Swedish Academy: Nobel Prize for Literature; - Committee composed of five persons of Parliament of Norway: Nobel Peace Prize Nobel prizes are awarded, so in 1901, except for economics, established in 1968 by the Central Bank of Sweden to commemorate the 300th anniversary of the founding of this institution. More specifically, Nobel Prizes have been awarded since December 10, 1901, after their author's death. They consist of: a medal, a diploma and a sum of money, which at first was worth U.S. $ 40,000, then increased to $ 1,000,000. Nobel Prize in cash value increased slightly since 1950, according to the Foundation website. Should mention that The Nobel Foundation has awarded prizes during World War or during World War II. Given these great discoveries of illustrious researchers could find solutions to global economic crisis. If so intense study should find

    To test if using a CAD/CAM system might reduce the necessity of bone augmentation in patients with atrophic maxillary arches before implant therapy. Twenty male and female patients consecutively scheduled for bone augmentation of the jaw before implant surgery were included in this study, with a total of 29 jaws (maxillary and mandibular) to analyze for the implant-supported fixed prosthesis group and 19 maxillary arches for the implant-supported removable prosthesis group. NobelGuide System (Nobel Biocare), Autocad System (Autodesk), and routine manual CT measurements of available bone were used in this study. The total results of the mean values of the fixed prosthesis group plus the mean values of the removable prosthesis group showed a statistically significant difference between the NobelGuide intervention score and both manual (P = .004) and Autocad (P = .001) measurements. The NobelGuide System represents a viable diagnostic device to reduce the entity or avoid bone reconstructive surgery before implant placements in the atrophic maxilla and mandible.

    Over the past 200 years, there have been countless groundbreaking discoveries in biology and medicine at Yale University. However, one particularly noteworthy discovery with profoundly important and broad consequences happened here in just the past two decades. In 2009, Thomas Steitz, the Sterling Professor of Molecular Biophysics & Biochemistry, was awarded the Nobel Prize in Chemistry for "studies of the structure and function of the ribosome," along with Venkatraman Ramakrishnan of the MRC Laboratory of Molecular Biology and Ada E. Yonath of the Weizmann Institute of Science. This article covers the historical context of Steitz's important discovery, the techniques his laboratory used to study the ribosome, and the impact that this research has had, and will have, on the future of biological and medical research.

    This year, 2011, the nobel prize in physics is given to three astronomers (Perlmutter, Schmidt, Riess) 'for the discovery of the accelerating expansion of the Universe through observations of distant supernovae'. In my seminar talk, I will thus present first some basic astrophysics on supernovae star explosions and the cosmological principle of an expanding Universe. Next, I will summarize the observations and measurements of the two teams behind the noble prize winners and show how the simplest explanations of the unexpected findings lead to the concept of an accelerating Universe. I will end my talk with an outlook on ongoing and future efforts to measure the equation-of-state of the Dark Energy postulated to explain the observations. (author)

    A grand scientific prize was awarded last year to three pioneering scientists, for their discovery and development of molecular ‘ON–OFF’ switching which, when combined with optical imaging, can be used to see the previously invisible with light microscopy. The Royal Swedish Academy of Science announced on October 8th their decision and explained that this achievement—rooted in physics and applied in biology and medicine—was awarded with the Nobel Prize in Chemistry for controlling fluorescent molecules to create images of specimens smaller than anything previously observed with light. The story of how this noble switch in optical microscopy was achieved and how it was engineered to visualize life at the nanoscale is highlighted in this invited comment. (invited comment)

  9. Was Muller's 1946 Nobel Prize research for radiation-induced gene mutations peer-reviewed?

    Science.gov (United States)

    Calabrese, Edward J

    2018-06-06

    This historical analysis indicates that it is highly unlikely that the Nobel Prize winning research of Hermann J. Muller was peer-reviewed. The published paper of Muller lacked a research methods section, cited no references, and failed to acknowledge and discuss the work of Gager and Blakeslee (PNAS 13:75-79, 1927) that claimed to have induced gene mutation via ionizing radiation six months prior to Muller's non-data Science paper (Muller, Science 66(1699):84-87, 1927a). Despite being well acclimated into the scientific world of peer-review, Muller choose to avoid the peer-review process on his most significant publication. It appears that Muller's actions were strongly influenced by his desire to claim primacy for the discovery of gene mutation. The actions of Muller have important ethical lessons and implications today, when self-interest trumps one's obligations to society and the scientific culture that supports the quest for new knowledge and discovery.

    The husband and wife Carl Ferdinand Cori (1896-1984) and Gerty Theresa Radnitz-Cori (1896-1957), two of five Prague-born Nobel laureates (the only ones in medicine), have so much slipped away from the citizens' memory in the course of the half-century totalitarian rule over the country of birth, that hardly anybody knows them nowadays, nothing to say of their relation to Prague. At pains to rescue them from oblivion, a recent search for the lost traces of Coris and their ancestors had revealed a number of hitherto unknown facts that have fundamentally contributed to the Corian genealogy; identification of both forgotten birth-houses (6 Salmovská st., 29 Petrská st.) at long last resulted in placement of memorial tablets (October 26th, 2000) to display the birth-place's pride and gratitude.

    Bond, Patrick

    2007-01-01

    The awarding of the 2006 Nobel Peace Prize to Muhammad Yunus, founder of the Grameen Bank, provides an opportunity to consider the use and abuse of microfinancing, especially because credit continues to be touted as a poverty-reduction strategy associated with health education and health care financing strategies. Not only is the Grameen diagnosis of poverty dubious, but many structural problems also plague the model, ranging from financial accounting to market failures. In Southern Africa, to illustrate, microcredit schemes for peasants and small farmers have been attempted for more than 70 years, on the basis that modem capitalism and peasant/informal system gaps can be bridged by an expanded financial system. The results have been disappointing. A critical reading of political economy posits an organic linkage between the "developed" and "underdeveloped" economies that is typically not mitigated by capitalist financial markets, but instead is often exacerbated. When applied to health and social policy, microcredit evangelism becomes especially dangerous.

    The Royal Swedish Academy awarded the Nobel Prize in Chemistry for 2015 to Tomas Lindahl, Paul Modrich and Aziz Sancar for their discoveries in fundamental mechanisms of DNA repair. This pioneering research described three different essential pathways that correct DNA damage, safeguard the integrity of the genetic code to ensure its accurate replication through generations, and allow proper cell division. Working independently of each other, Tomas Lindahl, Paul Modrich and Aziz Sancar delineated the mechanisms of base excision repair, mismatch repair and nucleotide excision repair, respectively. These breakthroughs challenged and dismissed the early view that the DNA molecule was very stable, paving the way for the discovery of human hereditary diseases associated with distinct DNA repair deficiencies and a susceptibility to cancer. It also brought a deeper understanding of cancer as well as neurodegenerative or neurological diseases, and let to novel strategies to treat cancer.

    A review of the theory developed by Rudolph A. Marcus is presented, who for his rating to the theory of electron transfer in chemical systems was awarded the Nobel Prize in Chemistry in 1992. Marcus theory has constituted not only a good extension of the use of a spectroscopic principle, but also has provided an energy balance and the application of energy conservation for electron transfer reactions. A better understanding of the reaction coordinate is exposed in terms energetic and establishing the principles that govern the transfer of electrons, protons and some labile small molecular groups as studied at present. Also, the postulates and equations described have established predictive models of reaction time, very useful for industrial environments, biological, metabolic, and others that involve redox processes. Marcus theory itself has also constituted a large contribution to the theory of complex transition [es

    2008-11-01

    The Nobel Prize in Physiology or Medicine in 1908 was awarded to Ilya I. Mechnikov and Paul Ehrlich for recognition of their work on immunity. Mechnikov have discovered phagocytes and phagocytosis as the basis of natural cellular immunity. His ,,phagocytic theory" is the principle of immunological concept "self and not self" as the prerequisition of physiological inflammation, and selfmaintaining of organism. Ehrlich developed the methods for standardization of antibody activity in immune sera, described neutralizing and complement-depending effect of antibodies and enunciated the ,"ide-chain" theory of the formation of antibodies. Their concept of the key-stone of immunity was different, but they expressed the basic paradigma of immunology: immunity imply the protection of identity and guarantee the integrity of organism. Both are the founders of immunology as the scientific discipline. Discoveries and conceptions of I. Mechnikov and P. Ehrlich exceedingly influenced development of immunology and are also applicable, instructive and suggestive in contemporary immunology and microbiology.

  15. INTRODUCTION: The Physics of Chaos and Related Problems: Proceedings of the 59th Nobel Symposium

    1985-01-01

    The physics of non-linear phenomena has developed in a remarkable way over the last couple of decades and has accelerated over the last few years, in particular because of the recent progress in the study of chaotic behaviour. In particular the discovery of the universal properties of the transition into chaos for certain classes of systems has stimulated much recent work in different directions both theoretically and experimentally. Chaos theory has become a real challenge to physicists in many different fields and also in many other disciplines such as astronomy, chemistry, medicine, meteorology and economics and social theory. The study of chaos-related phenomena has a truly interdisciplinary character and makes use of important concepts and methods from other disciplines. For the description of chaotic structures one needs a new, recently developed geometry called fractal geometry. For the discussion of the enormous richness of ordered structures which appear, one uses the theory of pattern recognition. In order to study even the simplest theoretical models describing chaos, a computer is essential. It should finally be mentioned that important aspects of computer science are related to the theory of order and chaos. A Nobel Symposium provides an excellent opportunity to bring together a group of prominent scientists for a stimulating exchange of new ideas and results. The Nobel Symposia are very small meetings by invitation only and the number of key participants is typically in the range 20-40. These symposia are organized through a special Nobel Symposium Committee after proposals from individuals. This symposium was sponsored by the Nobel Foundation through its Nobel Symposium Fund with grants from The Tercentenary Fund of the Bank of Sweden and The Knut Alice Wallenberg Foundation. Additional support was obtained from the Royal Academy of Sciences, The Nordic Institute for Theoretical Atomic Physics (NORDITA), Chalmers University of Technology and

    Full text: More than 60 of the world's leading cancer experts are being brought together in Buenos Aires, 23-27 April 2007, by the International Atomic Energy Agency (IAEA) to assess Latin America's growing cancerden. Poor medical facilities and lack of trained personnel and funding are limiting countries' ability to expand cancer care services and treat patients, while cancer rates are expected to double by 2020. More than 70 per cent of all cancer deaths occur in low and middle income countries and globally cancer kills more people than AIDS, malaria and tuberculosis combined. Through its Programme of Action for Cancer Therapy (PACT) the IAEA is using funds, awarded for the 2005 Nobel Peace Prize, to sponsor training workshops, such as the Buenos Aires event, that alert policy makers and health experts to the pressing need for national cancer control plans and programmes. 'I hope that this event in Latin America is the first of many that will enable us to work together to help combat this dreadful disease and provide quality of life to our fellow human beings,' said Director General of the IAEA, Dr. Mohamed ElBaradei. 'Cancer is a disease that is spreading very fast in the developing world and we have come to realise that we have to do much more to combat it in this part of the world.' In Latin America, there are an estimated 450,000 cancer deaths annually. The most commonly occurring cancers in men are prostate, stomach, lung, and colorectal and in women the most commonly occurring cancers are breast, cervix, stomach and colorectal. Breast and cervical cancer can be prevented through screening and early detection and can be cured in the early stages with effective treatment. The World Health Organization (WHO) warns that cancer will soon reach epidemic proportions, causing up to 10 million deaths a year by 2020. Yet at least one third of all cancers are preventable. A further one third of cases can be effectively treated if detected early. PACT was established

    Our research group has reconstructed why the board certified urologists Werner Forssmann (1904-1979) and Charles Huggins (1901-1997) received the Nobel Prize in physiology or medicine (1956, and 1966, respectively). But the history of "Urology and the Nobel Prize" is in fact more multifaceted than the success stories of these two laureates suggest. James Israel (1848-1926), Berlin, Félix Guyon (1831-1920), Paris, Peter J. Freyer (1852-1921), London and Edwin Beer (1876-1938), New York were nominated for the award during the first three decades of the 20th century. Their candidacies mirror trends among leading urologists during the time when urology became a specialty in its own right.

Ernest Rutherford (Nobel Banquet, 1908) This article is about how Ernest Rutherford (1871-1937) got the 1908 Nobel Prize in Chemistry and why he did not get a second Prize for his subsequent outstanding discoveries in physics, specially the discovery of the atomic nucleus and the proton. Who were those who nominated him and who did he nominate for the Nobel Prizes? In order to put the Prize issue into its proper context, I will briefly describe Rutherford's whereabouts. Rutherford, an exceptionally gifted scientist who revolutionized chemistry and physics, was moulded in the finest classical tradition. What were his opinions on some scientific issues such as Einstein's photon, uncertainty relations and the future prospects for atomic energy? What would he have said about the 'Theory of Everything'?

Ils ont participé de façon impressionnante à la remise en cause des valeurs, au démantèlement des dogmes et à l'irruption des forces cachées. On peut d'emblée souligner que la contribution des Juifs à la science a été sans commune mesure avec le pourcentage de la population qu'ils représentent. Cela reste vrai pour la chimie du XXe siècle. A travers la vie et l'oeuvre de 23 prix Nobel de chimie, l'auteur nous livre une histoire passionnante de ces hommes, biens souvent des exilés et d'origine modeste. dont la science fut leur vocation et le partage du savoir leur crédo.

    As a contribution to the celebration of the year 2014, declared by the United Nations to be 'The International Year of Crystallography', the FEBS Journal is dedicating this issue to papers showcasing the intimate union between macromolecular crystallography and structural biology, both in historical perspective and in current research. Instead of a formal editorial piece, by way of introduction, this review discusses the most important, often iconic, achievements of crystallographers that led to major advances in our understanding of the structure and function of biological macromolecules. We identified at least 42 scientists who received Nobel Prizes in Physics, Chemistry or Medicine for their contributions that included the use of X-rays or neutrons and crystallography, including 24 who made seminal discoveries in macromolecular sciences. Our spotlight is mostly, but not only, on the recipients of this most prestigious scientific honor, presented in approximately chronological order. As a summary of the review, we attempt to construct a genealogy tree of the principal lineages of protein crystallography, leading from the founding members to the present generation. Published 2014.

  7. Bad weather for the IPCC: from Nobel price to affairs, rise and fall of climate experts

    Dubuis, E.

    2010-01-01

    The intergovernmental panel on climate change, IPCC, or GIEC in French, has become in 20 years one of the most influent organization in the world. Awarded by the Nobel price of peace in 2007, this expression of the United Nations has succeeded in setting the fight against global warming at the top of the international political agenda, in particular during the 2009 Copenhagen meeting. What are the keys of this success? The IPCC has announced a global warming with disastrous effects, where floods would combine with dryness periods, epidemics and other natural disasters. Such a dark picture cannot leave anyone indifferent and allows the IPCC to encourage the humanity to drastically change its consumption habits and limit its way of life. However, to raise such fears and ask for such sacrifices, an organization like the IPCC must be irreproachable. And here is the problem reported in this book: the IPCC has shown its weaknesses, has made mistakes, has used unappropriated methods and miscasting personnel, has been uncapable to explain the complexness of the climate question and has felt reticent about the recognition of its mistakes. Revealed between fall 2009 and winter 2010, these failures have shaken the credibility of the organization to such a point that the UN requested an expertise to judge its own experts. (J.S.)

    This book is about the work of 10 great scientists; who they were and are, their personal background and how they achieved their outstanding results and took their prominent place in science history. We follow one of physics and science history's most enigmatic phenomena, superconductivity, through 100 years, from its discovery in 1911 to the present, not as a history book in the usual sense, but through close ups of the leading characters and their role in that story, the Nobel laureates, who were still among us in the years 2001-2004 when the main round of interviews was carried out. Since then two of them already passed away. For each one of the 10 laureates, the author tells their story by direct quotation from interviews in their own words. Each chapter treats one laureate. The author first gives a brief account of the laureates' scientific background and main contribution. Then each laureate tells his own story in his own words. This book is unique in its approach to science history.

IVF is nowadays a widely available and accepted method for helping infertile couples. However, the path to success was long and difficult. In this article, we present the development of IVF from the first ideas about fertilizing eggs outside the body from the end of the 19th century, followed by experiments on different animal species, the first human pregnancy and finally the birth of the first child in the United Kingdom. Many pioneers from other countries, particularly Australia and the United States of America, were instrumental in developing IVF as we know it today. Unfortunately, covering the history of IVF would greatly exceed the purpose of this article. During its history, the method was modified with innovative improvements. In its beginnings, there was a great deal of scepticism and opposition from certain public as well as scientific circles, an attitude that changed radically. The fact that the pioneer Robert Edwards received the Nobel Prize for Medicine in 2010 is proof of the growing acceptance of the method. Surely, IVF is a complex medical field, which raised and still raises ethical and legal questions. But from a merely human perspective, it is simply a method which gave infertile couples the opportunity to fulfill their lifetime dream.

  10. [An illustrious unknown. Giuseppe Levi among science, anti-fascism and Nobel Prizes].

    The anatomist Giuseppe Levi (1872-1965) is unanimously considered one of the major figures of Italian biomedical sciences in the 20th century. His fame, however, is mainly derived from having nurtured three Nobel Prize winners, namely Salvador E. Luria, Rita Levi Montalcini and Renato Dulbecco. In reappraising Levi's role in the development of Italian science and culture in general, this article aims at questioning both the narrowness of earlier accounts and a certain kind of genealogical approach to the history of scientific disciplines and academic schools. We will here consider Giuseppe Levi as an instance of two major cultural phenomena: the development of experimental biology in Italy and continental Europe and the anti-fascist socialist culture expressed by a part of the Italian intellectuals. In so doing, we will reassess the historical specificity of the scientific maturation of Levi's three famous students, on the one hand, while on the other we will consider in some depth the cultural and moral environment in which Levi thrived and his role as a moral example for his students. Such revision, we will argue, have a direct bearing on more general historiographical issues, namely, the need for a stronger contextualization of the birth and consolidation of research traditions, implying a rejection of simplistic genealogical reconstructions, and the role of academic schools and institutional settings in the definition of novel, multidisciplinary scientific approaches. Finally, the following will highlight the importance of a more careful outlook on the master-pupil relationship in academic context, addressing issues of both continuity and rupture. The article is subdivided in two main sections, the first devoted to Levi as a scientist, the second to his Anti-fascism.

    Marie Curie was awarded the Nobel Prize in 1903 and in 1911. Also her daughter, Irene Joliot-Curie, received a Nobel Prize for science in 1935. In this book an overview is given of the academic world at that time: limited access to universities for women, the carriers of both women in physics and their pioneering research and discoveries, the refusal of Marie Curie by the French Academy of Sciences, the awarding of the Nobel Prize and the assignment of Irene Joliot-Curie as the first female minister in France, the impact of the two World Wars, their married and private lives and the constant smear campaign of the press against both women. The lives and works of both women are hold against the light of the present position of women in physical sciences. [Dutch] In 1903, precies honderd jaar geleden, ontving Marie Curie als eerste vrouw de Nobelprijs voor de Wetenschap, gevolgd door een tweede Nobelprijs in 1911. Ook haar dochter Irene Joliot-Curie kreeg de Nobelprijs voor de wetenschap in 1935. Marie and Irene Curie schetst een breed beeld van de academische wereld waarin beide vrouwen zich bewogen: de beperkte toegang van vrouwen tot de universiteit, hun carrisres in de natuurkunde en baanbrekende ontdekkingen, de afwijzing van Marie door de Franse Academie des Sciences, de toekenning van de Nobelprijs en de benoeming van Irene als eerste vrouwelijke minister in Frankrijk, de invloed van de twee Wereldoorlogen, hun huwelijks- en priveleven en de niet aflatende hetze van de pers tegen beiden. In de door mannen gedomineerde wereld van de natuurwetenschappen liep de uitzonderingspositie van beide vrouwen als rode draad door hun curieuze levens. Het leven en werk van de Curies wordt geactualiseerd door deze tegen het licht te houden van de huidige positie van vrouwen in de natuurwetenschappen. Het bereiken van de top van de wetenschap door vrouwen blijkt nog steeds uitzonderlijk.

  20. Competitiveness of shallow water hydrocarbon development projects in Mexico after 2015 actualization of fiscal reforms: Economic benchmark of new production sharing agreement versus typical U.S. federal lease terms

    International Nuclear Information System (INIS)

    Weijermars, Ruud; Zhai, Jia

    2016-01-01

    Development of Mexican hydrocarbon reservoirs by foreign operators has become possible under Mexico's new Hydrocarbon Law, effective as per January 2015. Our study compares the economic returns of shallow water fields in the Gulf of Mexico applying the royalty and taxes due under the fiscal regimes of the U.S. and Mexico. The net present value (NPV) of the base case scenario is US$1.4 billion, assuming standard development and production cost (opex, capex), 10% discount rate accounting for the cost of capital and revenues computed using a reference oil price of $75/bbl. The impact on NPV of oil price volatility is accounted for in a sensitivity analysis. The split of the NPV of shallow water hydrocarbon assets between the two contractual parties, contractor and government, in Mexico and the U.S. is hugely different. Our base case shows that for similar field assets, Mexico's production sharing agreement allocates about $1,150 million to the government and $191 million to the contractor, while under U.S. license conditions the government take is about $700 million and contractor take is $553 million. The current production sharing agreement leaves some marginal shallow water fields in Mexico undeveloped for reasons detailed and quantified in our study. - Highlights: •Mexico's Energy Reform opens up the country to foreign petroleum companies. •Contractor and government takes are compared under each jurisdiction. •Contract terms for Mexico are much less favorable than those offered by the U.S.

    Inside wells, natural gases frequently coexist with water. The gases are in equilibrium with the sub-adjacent aquifer. Many problems are associated with the presence of water during the production, transport and processing of natural gases. Accurate knowledge of the thermodynamic properties of the water/hydrocarbon and water-inhibitor/hydrocarbon equilibria near the hydrate forming conditions, at sub-sea pipeline conditions and during the transport is crucial for the petroleum industry. An apparatus based on a static/analytic method combined with a dilutor apparatus to calibrate on the gas chromatograph (GC) detectors with water was used to measure the water content of binary systems (i.e.: water - methane, ethane - water, nitrogen - water...) as well of a synthetic hydrocarbon gas mixture (i.e.: 94% methane, 4% ethane and 2% n-butane) with and without inhibitor. This same apparatus was also used generate data of methane, ethane, propane, n-butane and nitrogen solubility in water and also the solubilities of a synthetic mixture in water. In-house software has been developed in order to fit and model the experimental data. (author)

  2. Horning cell self-digestion: Autophagy wins the 2016 Nobel Prize in Physiology or Medicine

    Directory of Open Access Journals (Sweden)

    Po-Yuan Ke

    2017-02-01

    Full Text Available Autophagy is an evolutionarily conserved process by which eukaryotic cells eliminate intracellular components via the lysosomal degradation process. This cell self-digestion process was first discovered and morphologically characterized in the late 1950s and early 1960s. The genetic screen studies in baker's yeast in the 1990s further identified the essential genes functioning in the autophagic process. In the past two decades, the detailed molecular process involved in the completion of autophagy was delineated. Additionally, autophagy has been implied to function in many aspects of biological processes, including maintenance of organelle integrity, protein quality control, regulation of the stress response, and immunity. In addition to maintain cell homeostasis, autophagy has recently been shown to be modulated and to participate in the pathogenesis of human diseases, such as pathogen infections, neurodegenerative diseases, and tumor development. Overall, the breakthrough in autophagy research relies on the discovery of autophagy-related genes (ATGs using a genetic screening approach in Saccharomyces cerevisiae, which was established by Yoshinori Ohsumi. This year the Nobel Committee has awarded Yoshinori Ohsumi the Nobel Prize in Physiology or Medicine for his remarkable contribution to autophagy research.

    Full Text Available In this paper the seminal results of the 2014 Nobel Prize in Physiology or Medicine Laureates are presented. First, a historical review of the development of our knowledge is provided along with the major paradigm shifts, by looking at the Nobel prizes awarded in the field of neuroscience in the last 110 years. We outline the major discoveries that were necessary for humankind to pass through the road leading to the remarkable understanding of high level mental functions, which led to this year’s Nobel Prize award. Next, the ground breaking discoveries of this year Nobel laureates are presented, which provide insights how neural representations of the environment are formed in the association cortices. These cortical areas are many synapses away from sensory receptors and motor outputs, and their activity do not reflect directly the activation patterns of the receptor population, but depends more strongly on intrinsic cortical computations. We also present how ensembles of specialized cells work together to compute complex cognitive functions and behaviour.

    2010-01-13

    American biochemist Roger Tsien shared the 2008 Nobel Prize in Chemistry with Martin Chalfie and Osamu Shimomura for their discovery and development of the Green Fluorescent Protein (GFP). Tsien, who was born in New York in 1952 and grew up in Livingston New Jersey, began to experiment in the basement of the family home at a young age. From growing silica gardens of colorful crystallized metal salts to attempting to synthesize aspirin, these early experiments fueled what would become Tsien's lifelong interest in chemistry and colors. Tsien's first official laboratory experience was an NSF-supported summer research program in which he used infrared spectroscopy to examine how metals bind to thiocyanate, for which he was awarded a $10,000 scholarship in the Westinghouse Science Talent Search. Following graduation from Harvard in 1972, Tsien attended Cambridge University in England under a Marshall Scholarship. There he learned organic chemistry --a subject he'd hated as an undergraduate-- and looked for a way to synthesize dyes for imaging neuronal activity, generating BAPTA based optical calcium indicator dyes. Following the completion of his postdoctoral training at Cambridge in 1982, Tsien accepted a faculty position at the University of California, Berkeley. There he and colleagues developed and improved numerous small molecule indicators, including indicators fura-2 and indo-1. In 1989, Tsien moved his laboratory to the University of California at San Diego, where he and his colleagues developed the enhanced mutant of GFP as a way to devise a cyclic AMP (cAMP) sensor for use in live cells. They initially engineered molecules to take advantage of the conformational change that occurs when cAMP binds to protein kinase A (PKA). By labeling one part of PKA with fluoroscein and another with a rhodamine, they hoped to detect Fluorescence Resonance Energy Transfer (FRET), which would occur when the two molecules were in close proximity.

    The intergovernmental panel on climate change, IPCC, or GIEC in French, has become in 20 years one of the most influent organization in the world. Awarded by the Nobel price of peace in 2007, this expression of the United Nations has succeeded in setting the fight against global warming at the top of the international political agenda, in particular during the 2009 Copenhagen meeting. What are the keys of this success? The IPCC has announced a global warming with disastrous effects, where floods would combine with dryness periods, epidemics and other natural disasters. Such a dark picture cannot leave anyone indifferent and allows the IPCC to encourage the humanity to drastically change its consumption habits and limit its way of life. However, to raise such fears and ask for such sacrifices, an organization like the IPCC must be irreproachable. And here is the problem reported in this book: the IPCC has shown its weaknesses, has made mistakes, has used unappropriated methods and miscasting personnel, has been uncapable to explain the complexness of the climate question and has felt reticent about the recognition of its mistakes. Revealed between fall 2009 and winter 2010, these failures have shaken the credibility of the organization to such a point that the UN requested an expertise to judge its own experts. (J.S.)

    'I have dealt with many different transformations with various periods of time, but the quickest that I have met was my own transformation in one moment from a physicist to a chemist.' Ernest Rutherford (Nobel Banquet, 1908) This article is about how Ernest Rutherford (1871-1937) got the 1908 Nobel Prize in Chemistry and why he did not get a second Prize for his subsequent outstanding discoveries in physics, specially the discovery of the atomic nucleus and the proton. Who were those who nominated him and who did he nominate for the Nobel Prizes? In order to put the Prize issue into its proper context, I will briefly describe Rutherford's whereabouts. Rutherford, an exceptionally gifted scientist who revolutionized chemistry and physics, was moulded in the finest classical tradition. What were his opinions on some scientific issues such as Einstein's photon, uncertainty relations and the future prospects for atomic energy? What would he have said about the 'Theory of Everything'?

    Secretion is widespread in all eukaryotic cells: all of us experience this in the course of daily life--saliva, mucus, sweat, tears, bile juice, adrenalin, etc.--the list is extremely long. How does a cell manage to repeatedly spit out some stuff without losing the rest? The answer is: through regulated vesicle trafficking within the cell. The Nobel Prize in Physiology or Medicine 2013 was awarded to Drs Randy Schekman, James E Rothman and Thomas C Südhof for their 'discoveries of machinery regulating vesicle traffic, a major transport system in our cells'. Dr Randy Schekman and his colleagues discovered a number of genes required for vesicle trafficking from the endoplasmic reticulum (ER) and Golgi; the James E Rothman group unravelled the protein machinery that allows vesicles to bud off from the membrane and fuse to their targets; and Dr Thomas C Südhof along with his colleagues revealed how calcium ions could instruct vesicles to fuse and discharge their contents with precision. These enabled the biotechnology industry to produce a variety of pharmaceutical and industrial products like insulin and hepatitis B vaccines, in a cost-efficient manner, using yeast and tissue cultured cells.

    Circadian clocks evolved to allow plants and animals to adapt their behaviors to the 24-hr change in the external environment due to the Earth's rotation. While the first scientific observation of circadian rhythm in the plant leaf movement may be dated back to the early 18th century, it took 200 years to realize that the leaf movement is controlled by an endogenous circadian clock. The cloning and characterization of the first Drosophila clock gene period in the early 1980s, independently by Jeffery C. Hall and Michael Rosbash at Brandeis University and Michael Young at Rockefeller University, paved the way for their further discoveries of additional genes and proteins, culminating in establishing the so-called transcriptional translational feedback loop (TTFL) model for the generation of autonomous oscillator with a period of ∼24 h. The 2017 Nobel Prize in Physiology or Medicine was awarded to honor their discoveries of molecular mechanisms controlling the circadian rhythm. Copyright © 2018 Chang Gung University.

  16. Do Nobel Laureates Create Prize-Winning Networks? An Analysis of Collaborative Research in Physiology or Medicine.

    Directory of Open Access Journals (Sweden)

    Caroline S Wagner

    Full Text Available Nobel Laureates in Physiology or Medicine who received the Prize between 1969 and 2011 are compared to a matched group of scientists to examine productivity, impact, coauthorship and international collaboration patterns embedded within research networks. After matching for research domain, h-index, and year of first of publication, we compare bibliometric statistics and network measures. We find that the Laureates produce fewer papers but with higher average citations. The Laureates also produce more sole-authored papers both before and after winning the Prize. The Laureates have a lower number of coauthors across their entire careers than the matched group, but are equally collaborative on average. Further, we find no differences in international collaboration patterns. The Laureates coauthor network reveals significant differences from the non-Laureate network. Laureates are more likely to build bridges across a network when measuring by average degree, density, modularity, and communities. Both the Laureate and non-Laureate networks have "small world" properties, but the Laureates appear to exploit "structural holes" by reaching across the network in a brokerage style that may add social capital to the network. The dynamic may be making the network itself highly attractive and selective. These findings suggest new insights into the role "star scientists" in social networks and the production of scientific discoveries.

    Santiago Ramón y Cajal was not only a great scientist but he was also a dedicated teacher who managed to create his own School in Spain. Cajal was active at the end of the XIX and the beginning of the XX century, a period in which Ivan Petrovich Pavlov, another great contemporary scientist, also established a strong School in Russia. While these two acclaimed scientists shared a similar vision on science, a view they also conveyed to their disciples, they applied quite distinct criteria in the way they dealt with their followers. Interestingly, despite the geographic and idiomatic barriers that had to be overcome, the paths of these two great figures of XX century science crossed at least three times. First when they competed for the City of Moscow Prize, second when they both attended the "Congreso Internacional de Medicina de Madrid" (Medicine International Congress in Madrid) in 1903 and finally, they competed on four consecutive occasions for the Nobel Prize in Physiology or Medicine. Here we discuss their scientific vision, their different attitudes in the interaction with disciples and the distinct circumstances in which their paths crossed.

  20. From the Proton Synchrotron to the Large Hadron Collider: 50 Years of Nobel Memories in High-Energy Physics

    CERN Multimedia

    Directorate Office

    As a new era in particle physics approaches with the start of the LHC, a symposium to commemorate many significant events that have marked high-energy physics in the past 50 years will be held at CERN on 3-4 December 2009. The list of confirmed distinguished speakers reads like the Who’s Who of particle physics of the second half of the 20th Century, including the Nobel Laureates James Cronin, Jerome Friedman, Sheldon Glashow, David Gross, Gerardus ‘t Hooft, Leon Lederman, Burton Richter, Carlo Rubbia, Jack Steinberger, Samuel Ting, Martinus Veltman, Stephen Weinberg and Frank Wilczek. They will share with us memories of several landmark events that, over the past 50 years, have shaped our field of science. These events include the discovery of the J/ψ particle by Richter and Ting in the 1970s; the work of Glashow, Salam and Weinberg on the theory of the unified weak and electromagnetic interactions; the discovery of fundamental asymmetries in the K-meson sector by Cronin and Fitch...

    The 2004 Nobel Prize in Physics was awarded to David J. Gross, Frank Wilczek and H. David Politzer for their decisive contributions to the theory of the asymptotic freedom of the strong interaction (a fundamental interaction). The fundamental elements of quantum chromodynamics (QCD) and the theory of the strong interaction are briefly reviewed in their historical context. How to achieve asymptotic freedom is introduced and its physical meaning explained. The latest experimental tests of asymptotic freedom are presented, and it is shown that the theoretical prediction agrees excellently with the experimental measurements. Perturbative QCD which is based on the asymptotic freedom is outlined. It is pointed out that the theoretical discovery and experimental proof of the asymptotic freedom are crucial for QCD to be the correct theory of strong interaction. Certain frontier research areas of QCD, such as 'color confinement', are mentioned. The discovery and confirmation of asymptotic freedom has indeed deeply affected particle physics, and has led to QCD becoming a main content of the standard model, and to further development of the so-called grand unification theories of interactions.

  2. In the service of peace: 2005 Nobel Peace prize[For the efforts to prevent nuclear energy from being used for military purposes and to ensure that nuclear energy for peaceful purposes is used in the safest possible way

    Nobel Citation: The Norwegian Nobel Committee has decided that the Nobel Peace Prize for 2005 is to be shared, in two equal parts, between the International Atomic Energy Agency (IAEA) and its Director General, Mohamed ElBaradei, for their efforts to prevent nuclear energy from being used for military purposes and to ensure that nuclear energy for peaceful purposes is used in the safest possible way. At a time when the threat of nuclear arms is again increasing, the Norwegian Nobel Committee wishes to underline that this threat must be met through the broadest possible international cooperation. This principle finds its clearest expression today in the work of the IAEA and its Director General. In the nuclear non-proliferation regime, it is the IAEA which controls that nuclear energy is not misused for military purposes, and the Director General has stood out as an unafraid advocate of new measures to strengthen that regime. At a time when disarmament efforts appear deadlocked, when there is a danger that nuclear arms will spread both to states and to terrorist groups, and when nuclear power again appears to be playing an increasingly significant role, IAEA's work is of incalculable importance. In his will, Alfred Nobel wrote that the Peace Prize should, among other criteria, be awarded to whoever had done most for the abolition or reduction of standing armies. In its application of this criterion in recent decades, the Norwegian Nobel Committee has concentrated on the struggle to diminish the significance of nuclear arms in international politics, with a view to their abolition. That the world has achieved little in this respect makes active opposition to nuclear arms all the more important today. The full Nobel Lecture of the Director General of the IAEA, Mr. Mohamed ElBaradei is given in this paper.

  3. Nobel prize for the artemisinin and ivermectin discoveries: a great boost towards elimination of the global infectious diseases of poverty.

    The Millennium Development Goals (MDGs) made a marked transformation for neglected and vulnerable communities in the developing countries from the start, but infectious diseases of poverty (IDoPs) continue to inflict a disproportionate global public health burden with associated consequences, thereby contributing to the vicious cycle of poverty and inequity. However, the effectiveness and large-scale coverage of artemisinin combination therapy (ACT) have revolutionized malaria treatment just as the control of lymphatic filariasis (LF) and onchocerciasis have benefitted from harnessing the broad-spectrum effect of avermectin-based derivatives. The paradigm shift in therapeutic approach, effected by these two drugs and their impact on community-based interventions of parasitic diseases plaguing the endemic low- and middle-income countries (LIMCs), led to the Nobel Prize in Physiology or Medicine in 2015. However, the story would not be complete without mentioning praziquantel. The huge contribution of this drug in modernizing the control of schistosomiasis and also some intestinal helminth infections had already shifted the focus from control to potential elimination of this disease. Together, these new drugs have provided humankind with powerful new tools for the alleviation of infectious diseases that humans have lived with since time immemorial. These drugs all have broad-spectrum effects, yet they are very safe and can even be packaged together in various combinations. The strong effect on so many of the great infectious scourges in the developing countries has not only had a remarkable influence on many endemic diseases, but also contributed to improving the cost structure of healthcare. Significant benefits include improved quality of preventive and curative medicine, promotion of community-based interventions, universal health coverage and the fostering of global partnerships. The laudable progress and benefits achieved are indispensable in championing

    Full Text Available The remarkable achievements of one of the world's greatest entrepreneurs offer profound insights into the fundamental nature of economy and essential missing links in prevailing economic theory. The career of Steve Jobs dramatically illustrates the central importance of human capital in modern economy and the almost incalculable contribution that a single individual can make to technological advancement, social innovation and wealth creation, while enhancing the lifestyle of hundreds of millions of people. Jobs demonstrated that the real basis of economic value is providing valuable products and services that fulfill human needs and aspirations, not unregulated markets and financial speculation. His apparent failures point to the dual nature of uncertainty that presides over all human activity - both the ever present threat of error and the untold opportunities hidden behind the veil. Widely regarded as a genius for inventing better products, his greatest commercial achievement has been in recognizing the central importance of services in modern society and fashioning integrated social service systems within which products act as an enabling technology.

    Tadeus Reichstein (1897-1996) was the first scientist born in Poland to receive the Nobel Prize in Medicine or Physiology (1950) for the "discovery of hormones of the adrenal cortex, their structure and biological effects", as stated by the Nobel Prize Committee. His family being deeply devoted to Polish cultural and historical heritage, his first name was given to him after Tadeus Kosciuszko, a chief commander of the 18th century Polish uprising named the Kosciuszko Insurrection. As a child, he emigrated with his family to Switzerland, where he was much later to become involved in numerous research studies on steroids on an international scale. It was Tadeus Reichstein who isolated and synthesized desoxycorticosterone, which still remains the drug of first choice in the treatment of Addison's disease. Additionally, thanks to his strategy for the mass production of Vitamin C, the cost of this agent was drastically reduced thus enabling its widespread therapeutic use. In our divided world so often torn by tremendous conflicts, there is a great need to both remember and commemorate such distinguished people as Tadeus Reichstein who, despite the apparent "borders" between different nationalities and cultures, have demonstrated through their work the huge need for harmonious collaboration in the development of science.

    Full Text Available The Irish revolutionary Roger Casement, executed in 1916, has spawned an army of books, articles, and news stories, more about his diaries and the authenticity controversy that still surrounds them than about his seminal work encouraging and arming Irish separatism or his humanitarian investigations in the Congo and the Peruvian Amazon. His aura and image in life, and more so in death, was Christ-like. A cult developed that required him to be sexless. The more he was said to be an active homosexual, as graphically revealed in his journals, ironically, the more he was revered as an icon by his Catholic nationalist supporters. The entry of Nobel prizewinning novelist Mario Vargas Llosa to the field and his adoption of a mixed, even contradictory, view of Casement’s sexuality in his Dream of the Celt (2010 has sparked a new round of disputation particularly from Angus Mitchell, the foremost proponent of the diary forgery theory. This emerges in his extensive Field Day Review articles, one of which provides a full history of the controversy.

    The publication abstracted reports on the history and aims of IPPNW (International Physicians for the Prevention of Nuclear War). In recognition of their continuous and consistent international campaign of enlightenment its 140,000 members were awarded the peace Nobel prize in 1985. Emphasis is placed on the achievements and work of the Western Germany section of ''Physicians for the Prevention of Nuclear War''. The portrait is the first of its kind to comprehensibly acquaint even non-experts with the background, history and difficulties of the medical resistance to the dangers of nuclear war. Neither stopping at national or at political borders the medical hippocratic mission of fighting against a nuclear holocaust has brought about and developed a professional disinterestedness which is not equalled by any other kind of social and moral devotion. The publication analyses the worldwide threatening situation, the forgotten lesson taught by the past and the chances of medical protest. The result pointed out expresses an optimistic view. Chances are good if IPPNW does not only supply us with facts but also sets an example of modern morality. Interesting rudimentary attempts of initation can already be observed with other professions, for example among journalists.

This award underlines also Professor Crutzen`s commitment to the protection of the atmosphere. The atmospheric researcher discovered how sensitively the ozone layer reacts to air pollution. His work, together with that of others, led to the ban on ozone-depleting chlorofluorocarbons. As early as in 1970, Professor Crutzen demonstrated that nitrogen oxides react catalytically with ozone. His think tank provided numerous stimuli for further, intense research on atmospheric chemistry, which triggered a debate on the protection of the thinning ozone layer also among politicians. (orig.)

    Full Text Available Shh, Respect Freedom of Speech: The Reasons Why Ngugi wa Thiong’o and Ismail Kadare Have Not Been Awarded the Nobel Prize Abstract The terrorist attack on the satirical French magazine, Charlie Hebdo, at the beginning of this year, intensified the unremitting debate over the right to freedom of speech and expression, as well as its limitations. Nonetheless, it was almost unanimously agreed that the human right to express personal beliefs, regardless of the fact that they could be in deep disagreement with or even insulting towards the values of certain individuals, groups, or worldviews, should be defended and promoted by the whole human community. It goes without saying that the role of intellectuals and, especially, that of the academia, in promoting tolerance, diversity, and dialogue is essential. However, this does not seem to have been one of the criteria on which the Swedish Academy based its choices, over the past years, for the awarding of the Noble Prize in Literature. Focusing on the literary contributions of Ngugi wa Thiong’o and Ismail Kadare, two repeated nominees for the Noble Prize, this paper will attempt to shed light on the reasons why these two “heroes” of free speech and representation have not been awarded the prestigious prize.

    Transition metal‐catalyzed decarbonylative coupling reactions have emerged as a powerful alternative to conventional cross‐coupling protocols due to the advantages associated with the use of carbonyl‐containing functionalities as coupling electrophiles instead of commonly used organohalides or sulfates. A wide variety of novel transformations based on this concept have been successfully achieved, including decarbonylative carbon–carbon and carbon–heteroatom bond forming reactions. In this Review, we summarize the recent progress in this field and present a comprehensive overview of metal‐catalyzed decarbonylative coupling reactions with carbonyl derivatives.

Small scale experiments using 40-50 mL of feed simulant in closed glass reactors (250-550 mL total volume) at 80-100 degree C were used to study the effect of nitrite and nitrate ion on the catalytic activities of the noble metals for formic acid decomposition. Reactions were monitored using gas chromatography to analyze the CO 2 , H 2 , NO, and N 2 O in the gas phase as a function of time. Rhodium, which was introduced as soluble RhCl 3 ·3H 2 O, was found to be the most active catalyst for hydrogen generation from formic acid above ∼80 degree C in the presence of nitrite ion in accord with earlier observations. The inherent homogeneous nature of the nitrite-promoted Rh-catalyzed formic acid decomposition is suggested by the approximate pseudo first-order dependence of the hydrogen production rate on Rh concentration. Titration of the typical feed simulants containing carbonate and nitrite with formic acid in the presence of rhodium at the reaction temperature (∼90 degree C) indicates that the nitrite-promoted Rh-catalyzed decomposition of formic acid occurs only after formic acid has reacted with all of the carbonate and nitrite present to form CO 2 and NO/N 2 O, respectively. The catalytic activities of Ru and Pd towards hydrogen generation from formic acid are quite different than those of Rh in that they are inhibited rather than promoted by the presence of nitrite ion

    Atomically dispersed supported metal catalysts are drawing wide attention because of the opportunities they offer for new catalytic properties combined with efficient use of the metals. We extend this class of materials to catalysts that incorporate atomically dispersed metal atoms as promoters. The catalysts are used for the challenging nitroarene hydrogenation and found to have both high activity and selectivity. The promoters are single-site Sn on TiO2 supports that incorporate metal nanoparticle catalysts. Represented as M/Sn-TiO2 (M = Au, Ru, Pt, Ni), these catalysts decidedly outperform the unpromoted supported metals, even for hydrogenation of nitroarenes substituted with various reducible groups. The high activity and selectivity of these catalysts result from the creation of oxygen vacancies on the TiO2 surface by single-site Sn, which leads to efficient, selective activation of the nitro group coupled with a reaction involving hydrogen atoms activated on metal nanoparticles.

    The cobalt-catalyzed alternating copolymerization of epoxides and CO is a novel, direct approach to aliphatic polyesters, such as poly(hydroxybutyrate) (PHB). This reaction was found to be catalyzed by Ph3Si[Co(CO)4] (4) and pyridine affording in a first step the stable mono-insertion product Ph3Si-O-CH(CH3)-CH2-CO-Co(CO)4 (5). However, a profound mechanistic understanding, especially of the role of pyridine as the key component for the polymerization reaction was missing. ATR-IR online monitoring under catalytic conditions and DFT calculations were used to show that an acylpyridinium cation is formed by cleavage of the cobalt-acyl bond of 5 in the presence of pyridine. The Lewis acid thus generated activates the next incoming epoxide monomer for ring opening through [Co(CO)4]-. The catalytic cycle is completed by a subsequent CO insertion in the new cobalt-alkyl bond. The calculations are used to explore the energetic hypersurface of the polymerization reaction and are complemented by extended experimental investigations that also support the mechanistic hypotheses.

    Transition-metal (TM)-catalyzed hydroarylation reactions of alkynes have received much attention, because they enable the net insertion of alkyne C-C triple bonds into C-H bonds of aromatic precursors, resulting in regio- and stereo-selective formation of synthetically useful arylalkenes. Taking advantage of this feature, TM-catalyzed alkyne hydroarylations have been successfully used for the synthesis of heterocycles. TM-catalyzed alkyne hydroarylations can be classified into three major categories depending on the type of reaction and precursors involved: (1) palladium-catalyzed reductive Heck reactions of alkynes with aryl halides, (2) TM-catalyzed conjugate arylation reactions of activated alkynes with arylboronic acids, and (3) TM-catalyzed aromatic C-H alkenylations with alkynes. This review surveys heterocycle synthesis via TM-catalyzed hydroarylation of alkynes according to the above classification, with an emphasis on the scope and limitations, as well as the underlying mechanisms.

    2018-05-14

    Transition metal‐catalyzed decarbonylative coupling reactions have emerged as a powerful alternative to conventional cross‐coupling protocols due to the advantages associated with the use of carbonyl‐containing functionalities as coupling electrophiles instead of commonly used organohalides or sulfates. A wide variety of novel transformations based on this concept have been successfully achieved, including decarbonylative carbon–carbon and carbon–heteroatom bond forming reactions. In this Review, we summarize the recent progress in this field and present a comprehensive overview of metal‐catalyzed decarbonylative coupling reactions with carbonyl derivatives.

    There is a necessity of studies documenting the long-term outcome of full-arch flapless rehabilitations. To evaluate the 7 years implant and prosthesis survival rate and 5-years marginal bone loss of full-arch fixed prosthetic rehabilitations supported by implants in immediate function with the All-on-4 ® treatment concept using a computer guided surgical protocol (NobelGuide ® , Nobel Biocare). This retrospective clinical study included 111 edentulous patients (n = 53 bruxers; n = 21 smokers; n = 59 systemically compromised), rehabilitated between February 2005 and November 2010 with 532 implants with the All-on-4 ® treatment concept using NobelGuide ® . Outcome measures were implant and prosthesis survival, marginal bone loss at 5-years and the incidence of mechanical and biological complications. Survival was calculated using life-table analysis. Inferential analysis was performed to compare the difference in marginal bone loss between axial and tilted implants. Sixteen patients were lost to follow-up. The implant cumulative survival rate was 94.5% at 7 years. Prosthetic survival was 97.8% (n = 3 prosthetic failures). The average (standard deviation) marginal bone loss at 5 years was 1.3 mm (1.06 mm) overall, 1.27 mm (1.02 mm) for tilted implants and 1.34 mm (1.1 mm) for axial implants (p < .001). Ninety-one patients experienced complications in the provisional prostheses (n = 47 patients who were bruxers; n = 25 patients with implant-supported rehabilitation as opposing dentition) ranging from prosthetic fracture (n = 66 patients) to abutment or prosthetic screw loosening (n = 74 patients). Thirty-three patients experienced complications in the definitive prostheses (all exclusive to patients who were bruxers or had implant-supported rehabilitations as opposing dentition) ranging from acrylic-resin prosthetic/crown fracture (n = 23 patients) to abutment or prosthetic screw loosening (n = 10 patients).

  9. The Importance of Water-Hydrocarbon Phase Equilibria During Reservoir Production and Drilling Operations Nouveaux défis liés à la présence d'équilibres eau-hydrocarbures lors des opérations de production et de forage

    Full Text Available The inevitable presence of water in high pressure-high temperature reservoirs leads to a number of new challenges for petroleum engineers. A brief state of the art on water-hydrocarbon phase equilibria is presented. It appears that large amounts of water may be present in the hydrocarbon phase (up to 10% molar, and non negligible amounts of gas can dissolve in water. Based on experimental data, a large number of models have been developed. However, concerning the limitations of the data, caution is expressed about the correctness of some models. Recent studies have proven the usefulness of Henry's constants to predict hydrocarbon solubilities in water. The new challenges that are raised by this problem are discussed based on a number of recent publications. The water present in the hydrocarbon may lead to salt deposits downwell, and it must be taken into account in order to estimate the amount of gas in place. It can also result in modifications of the saturation pressure. Due to the presence of water, additional treatment is needed for pipe transport. On the other hand, the large amount of hydrocarbons dissolved in the water phase may result in a modification of the hydrocarbon composition, especially when reservoir pressure becomes very low. The increased toxicity of the water, containing either H2S or aromatics, can become a real burden for gas reservoirs in contact with aquifers or when disposing of production water. During drilling, large amounts of dissolved gas can become very hazardous, increasing the risk of eruption. A particular attention must be paid to acid gas injection in reservoirs, as the true effect of the injected gas may not be straightforward to predict. In conclusion, in light of the industrial importance of this information, some general guidelines are provided concerning additional data to be gathered and ideas for improving current models.

    ¿Porqué el Premio Nobel 1991? Erwin Neher y el “Patch Clamp”

    (Con autorización especial del autor y de la revista “Consulta” de España.

    El profesor Erwin Neher es un científico alemán de cuarenta y cinco años que ideó la técnica conocida con las palabras inglesas “patch clamp”, que en castellano viene él significar “fijación de voltaje en parches de la membrana celular”. A veces, una nueva metodología facilita el avance científico de forma vertiginosa. Tal es el caso del “patch clamp”, que en la última década ha permitido catalogar decenas de canales iónicos de decenas de células excitables y no excitables, y ha hecho posible el análisis exhaustivo de las propiedades cinéticas de su apertura y cierre, de su regulación por neurotransmisores y hormonas, así como la identificación de la subunidades peptídicas implicadas en la estructura y función de muchos de esos canales.

    Recientemente, me comentaba un colega que los que nos dedicamos a este campo estamos encontrando en las células más canales que en Venecia. Dejando aparte ese comentario irónico, lo cierto es que hoy contamos por decenas los subtipos de canales de potasio, se han identificado ya media docena de canales de calcio y se están descubriendo otros nuevos de cloro o de sodio. Unos se activan e inactivan por cambios del potencial de membrana (los denominados canales voltaje-dependientes y otros por neurotransmisores específicos (los llamados canales operados por receptores.

    Esta variedad de canales abre múltiples caminos para el diseño de fármacos que modulen específicamente uno u otro canal y que, por consiguiente, tienen una notoria potencialidad terapéutica. ¿Cómo se llegó al

    The α-aminoketone 1,4-diamino-2-butanone (DAB), a putrescine analogue, is highly toxic to various microorganisms, including Trypanosoma cruzi. However, little is known about the molecular mechanisms underlying DAB's cytotoxic properties. We report here that DAB (pK(a) 7.5 and 9.5) undergoes aerobic oxidation in phosphate buffer, pH 7.4, at 37°C, catalyzed by Fe(II) and Cu(II) ions yielding NH(4)(+) ion, H(2)O(2), and 4-amino-2-oxobutanal (oxoDAB). OxoDAB, like methylglyoxal and other α-oxoaldehydes, is expected to cause protein aggregation and nucleobase lesions. Propagation of DAB oxidation by superoxide radical was confirmed by the inhibitory effect of added SOD (50 U ml-1) and stimulatory effect of xanthine/xanthine oxidase, a source of superoxide radical. EPR spin trapping studies with 5,5-dimethyl-1-pyrroline-1-oxide (DMPO) revealed an adduct attributable to DMPO-HO(•), and those with α-(4-pyridyl-1-oxide)-N-tert-butylnitrone or 3,5-dibromo-4-nitrosobenzenesulfonic acid, a six-line adduct assignable to a DAB(•) resonant enoyl radical adduct. Added horse spleen ferritin (HoSF) and bovine apo-transferrin underwent oxidative changes in tryptophan residues in the presence of 1.0-10 mM DAB. Iron release from HoSF was observed as well. Assays performed with fluorescein-encapsulated liposomes of cardiolipin and phosphatidylcholine (20:80) incubated with DAB resulted in extensive lipid peroxidation and consequent vesicle permeabilization. DAB (0-10 mM) administration to cultured LLC-MK2 epithelial cells caused a decline in cell viability, which was inhibited by preaddition of either catalase (4.5 μM) or aminoguanidine (25 mM). Our findings support the hypothesis that DAB toxicity to several pathogenic microorganisms previously described may involve not only reported inhibition of polyamine metabolism but also DAB pro-oxidant activity.

    Aqueous phase hydrodeoxygenation of lignin pyrolysis oil and related model compounds were investigated using four noble metals supported on activated carbon. The hydrodeoxygenation of guaiacol has three major reaction pathways and the demethylation reaction, mainly catalyzed by Pd, Pt and Rh, produces catechol as the products. The presence of catechol and guaiacol in the reaction is responsible for the coke formation and the catalysts deactivation. As expected, there was a significant decrease in the specific surface area of Pd, Pt and Rh catalysts during the catalytic reaction because of the coke deposition. In contrast, no catechol was produced from guaiacol when Ru was used so a completely hydrogenation was accomplished. The lignin pyrolysis oil upgrading with Pt and Ru catalysts further validated the reaction mechanism deduced from model compounds. Fully hydrogenated bio-oil was produced with Ru catalyst.

    Simulants for the Hanford Waste Vitrification Plant feed containing the major non-radioactive components Al, Cd, Fe, Mn, Nd, Ni, Si, Zr, Na, CO 3 2 -, NO 3 -, and NO 2 - were used to study reactions of formic acid at 90 degrees C catalyzed by the noble metals Ru, Rh, and/or Pd found in significant quantities in uranium fission products. Such reactions were monitored using gas chromatography to analyze the CO 2 , H 2 , NO, and N 2 O in the gas phase and a microammonia electrode to analyze the NH 4 +/NH 3 in the liquid phase as a function of time. The following reactions have been studied in these systems since they are undesirable side reactions in nuclear waste processing: (1) Decomposition of formic acid to CO 2 + H 2 is undesirable because of the potential fire and explosion hazard of H 2 . Rhodium, which was introduced as soluble RhCl 3 -3H 2 O, was found to be the most active catalyst for H 2 generation from formic acid above ∼ 80 degrees C in the presence of nitrite ion. The H 2 production rate has an approximate pseudo first-order dependence on the Rh concentration, (2) Generation of NH 3 from the formic acid reduction of nitrate and/or nitrite is undesirable because of a possible explosion hazard from NH 4 NO 3 accumulation in a waste processing plant off-gas system. The Rh-catalyzed reduction of nitrogen-oxygen compounds to ammonia by formic acid was found to exhibit the following features: (a) Nitrate rather than nitrite is the principal source of NH 3 . (b) Ammonia production occurs at the expense of hydrogen production. (c) Supported rhodium metal catalysts are more active than rhodium in any other form, suggesting that ammonia production involves heterogeneous rather than homogeneous catalysis

Este método se fundamenta en la formación de depósitos opacos intracelulares de cromato argéntico, producto de la reacción entre el bicromato de potasio y el nitrato de plata (reacción negra. Camillo Golgi, su descubridor, y Santiago Ramón y Cajal, su principal exponente, recibieron el premio nobel de Medicina y Fisiología en 1906 por su contribución al conocimiento de la estructura del sistema nervioso. Gran parte de sus logros se obtuvieron a través de la aplicación del método de impregnación argéntica. Sin embargo, Golgi y Cajal tenían interpretaciones diferentes sobre la estructura del tejido nervioso. Golgi era defensor de la teoría reticular, la cual proponía que el sistema nervioso estaba conformado por una red de células fusionadas a través de los axones a manera de un sincitio. Por el contrario, la doctrina neuronal, defendida por Cajal, sostenía que las neuronas eran células independientes. También se debe a Golgi y su reazione nera el descubrimiento del organelo celular conocido como ‘aparato de Golgi'. La microscopía electrónica confirmó los postulados de la doctrina neuronal, así como la existencia del complejo de Golgi, y contribuyó al resurgimiento de la técnica de impregnación argéntica. Aunque existen métodos modernos de tinción intracelular que revelan imágenes excelentes de la morfología neuronal, la técnica de Golgi se mantiene vigente por ser un método más práctico y menos costoso para el estudio de la morfología normal y patológica de las neuronas.

  9. Nobel Lecture: From the Big Bang to the Nobel Prize and beyond

    Mather, John C.

    NASA’s Cosmic Background Explorer satellite mission, the COBE, laid the foundations for modern cosmology by measuring the spectrum and anisotropy of the cosmic microwave background radiation and discovering the cosmic infrared background radiation. I describe the history of the COBE project, its scientific context, the people who built it, and the scientific results. The COBE observed the universe on the largest scales possible by mapping the cosmic microwave and infrared background radiation fields and determining their spectra. It produced conclusive evidence that the hot Big Bang theory of the early universe is correct, showed that the early universe was very uniform but not perfectly so, and that the total luminosity of post Big Bang objects is twice as great as previously believed. The COBE concept was developed by a Mission Definition Study Team appointed by NASA in 1976, based on three competing proposals submitted in 1974. The COBE was built in-house by Goddard Space Flight Center, with a helium cryostat provided by Ball Aerospace, and was launched on a Delta rocket built by McDonnell Douglas. It is in a circular orbit 900km above the Earth, in a plane inclined 99° to the equator and roughly perpendicular to the line to the Sun. It carried three instruments, a far infrared absolute spectrophotometer (FIRAS), a differential microwave radiometer with three channels (DMR), and a diffuse infrared background experiment (DIRBE). The helium cryostat cooled the FIRAS and DIRBE for 10months until the helium was exhausted, but operations continued for a total of 4years . Subsequent observations have confirmed the COBE results and led to measurements of the main cosmological parameters with a precision of a few percent.

    Simulants for the Hanford Waste Vitrification Plant feed containing the major nonradioactive components Al, Cd, Fe, Mn, Nd, Ni, Si, Zr, Na, CO 3 2- , NO 3 - , and NO 2 - were used to study redox potential changes in reactions of formic acid at 90 C catalyzed by the noble metals Ru, Rh, and/or Pd found in significant quantities in uranium fission products. Such reactions were monitored using gas chromatography to analyze the CO 2 , H 2 , NO, and N 2 O in the gas phase and a redox electrode to follow redox potential changes as a function of time. In the initial phase of formic acid addition to nitrite-containing feed simulants, the redox potential of the reaction mixture rises typically to +400 mV relative to the Al/AgCl electrode because of the generation of the moderately strongly oxidizing nitrous acid. No H 2 production occurs at this stage of the reaction as long as free nitrous acid is present. After all of the nitrous acid has been destroyed by reduction to N 2 O and NO and disproportionation to NO/NO 3 - , the redox potential of the reaction mixture becomes more negative than the Ag/AgCl electrode. The experiments outlined in this paper suggest the feasibility of controlling the production of H 2 by limiting the amount of formic acid used and monitoring the redox potential during formic acid treatment

    Cigarette Disinformation: Origins and Global Impact Robert N. Proctor The cigarette is the deadliest artifact in the history of human civilization. And whereas "only" a hundred million people died in the 20th century from smoking, we are presently on a pace to have several times that toll in the present century. Much of that catastrophe would not be possible without a massive campaign of disinformation. The cigarette industry pioneered many of the black arts of disinformation, cleverly exploiting the inherent skepticism of science to claim that "more research" was needed to resolve a purported "cigarette controversy." Cigarette makers funded hundreds of millions of dollars worth of "distraction research," most of which was solid empirical science but off topic, focusing on basic biology and biochemistry, viral and genetic causes of disease, and other "cigarette friendly" topics. At least ten Nobel prizes were the result. Cigarette skepticism was thus more complex than we normally imagine: the tobacco industry corrupted science by funding "alternative causation," meaning anything that could be used to draw attention away from cigarettes as a source of disease. The cigarette industry by this means became the most important source of academic corruption since the Nazi era. That corruption has also helped forge other forms of denialism and corruption on a global scale.

  19. Modeling land subsidence due to shallow-water hydrocarbon production: A case study in the northern Adriatic Sea

    Gambolati, G.; Castelletto, N.; Ferronato, M.; Janna, C.; Teatini, P.

    2012-12-01

    One major environmental concern of subsurface fluid withdrawal is land subsidence. The issue of a reliable estimate and prediction of the expected anthropogenic land subsidence is particularly important whenever the production of hydrocarbon (oil and gas) occurs from large reservoirs located close to deltaic zones (e.g., Mississippi, Po, Nile, Niger, Yellow rivers) or shallow-water with low-lying coastlands (e.g., Northern Caspian sea, Dutch Wadden Sea). In such cases even a small reduction of the ground elevation relative to the mean sea level may impact seriously on human settlements and natural environment. The monitoring of the ongoing land subsidence has been significantly improved over the last decade by SAR-based interferometry. These measurements can be quite effectively used to map the process and calibrate geomechanical models for predicting the future event. However, this powerful methodology cannot be implemented off-shore. Although permanent GPS stations can be established to monitor the movement of the production facilities usually installed above the gravity center of a reservoir, an accurate characterization of the settlement bowl affecting the sea bottom, with a possible migration toward the shore, is a challenge still today. In the present communication the case study of the Riccione gas reservoir is discussed. The field is located in the near-shore northern Adriatic Sea, approximately 15 km far from the coastline, where the seawater height is about 20 m. The gas-bearing strata are 1100 m deep and are hydraulically connected to a relatively weak aquifer. Production of 70% of the cumulative reserves as of 2006 yielded a pore pressure decrease of 60 bars. Reliable geometry and geomechanical properties of the depleted formations were detected with the aid of a 3D seismic survey and a borehole equipped with radioactive markers, respectively. The latter pointed out that the Riccione formations are characterized by an unusually high oedometer compressibility approximately 5 times larger than typical values found in the northern Adriatic sedimentary basin. Based on the pore pressure computed by a flow-dynamic model calibrated against the measured pressure records, a 3D finite-element geomechanical model was developed and used to assess land subsidence caused by the field development. As of 2006 a maximum subsidence of 85 cm was predicted, with the bowl extension confined above the trace of the reservoir. An a-posteriori survey of the Adriatic bathymetry by multibeam revealed that not only the maximum value but also the shape of the anthropogenic subsidence pattern was satisfactorily matched by the modeling results. This outcome helps add confidence in the reliability of computational modeling whenever an accurate characterization of the reservoir geometry and a good estimate of the petrophysical /geomechanical properties of the porous medium are available.

    With his discovery that measuring values of complementary fundamental quantities in the microscopic world cannot by arbitrarily precisely determined cutted Werner Heisenberg the Gordian knot for the finishing of quantum theory developed by Planck, Einstein, and others and opened by this a new ''golden era'' in the physics of the 20th century. On the base of the documents from his life and work, i. e. deeds, letters and reports of contemporaries, as well as the published and unpublished essays, books, and articles of Heisenberg - also the later on found, publications or manuscripts mainly coming from the inheritance - resulted this systematic biography of Heisenberg. The author, the last doctoral candidate of Heisenberg relied furthermore on factual and personal knowledges, mainly own remembrances on his doctoral father and his teachers, colleagues, and students. Because of the interest of an authentical biography of the theoretical physicist Heisenberg the presentation of the mathematical approaches and the corresponding derivations could not completely be abandoned. This biography appeals by this both to a scientifically cultivated as a wider in science interested audience and covers the first phase of Heisenberg's life until his Nobel price 1933.

Starting from the description of different ways in which some urban spaces in Rome (Italy are used by two different communities of people, one mainly composed by immigrants and the other by young city users, and the diverse ways in which their different practices are seen and tolerated, the aim of this paper is to reflect on public spaces. Observing how city users practice public spaces, and analysing the way in which these practices are considered, are particularly exciting perspectives that can offer an interesting vision of the spatial and social reality of the city and of hegemonic relations which govern it.

    To a large extent, the field of "molecular machines" started after several groups were able to prepare, reasonably easily, interlocking ring compounds (named catenanes for compounds consisting of interlocking rings and rotaxanes for rings threaded by molecular filaments or axes). Important families of molecular machines not belonging to the interlocking world were also designed, prepared, and studied but, for most of them, their elaboration was more recent than that of catenanes or rotaxanes. Since the creation of interlocking ring molecules is so important in relation to the molecular machinery area, we will start with this aspect of our work. The second part will naturally be devoted to the dynamic properties of such systems and to the compounds for which motions can be directed in a controlled manner from the outside, that is, molecular machines. We will restrict our discussion to a very limited number of examples which we consider as particularly representative of the field. © 2017 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.

    The influence of the reconstructed (0001) α-Al 2 O 3 surface on the heteroepitaxial growth and adhesion properties of small metal particles (gold, silver and copper) of noncontinuous thin films has been investigated. The crystallographic structure and morphology of substrate surfaces were examined by Reflection High Energy Electron Diffraction and Atomic Force Microscopy techniques. The reconstructed surfaces are terminated by one or more Aluminum atomic layers. By means of the Transmission Electronic Microscopy, the various granulometric and lattice parameters variations are investigated during different stages of the heteroepitaxial growth of metallic thin films. We estimated the adhesion energy values for each case of metal//(0001)α-Al 2 O 3 interfaces by two methods: the maximum cluster density and the Lifshits theory of Van der Waals energy of interfaces. The results of both methods are in good agreement. Using these methods, we found interfaces Hamaker's constants values and we investigated all the heteroepitaxial growth steps.(author)

    Noble gases (argon, krypton, and xenon) are puffed into vacuum through a nozzle to produce clusters for studying laser-cluster interactions. Good estimates of the average size of the argon, krypton and xenon clusters are made by carrying out a series of Rayleigh scattering experiments. In the experiments, we have found that the scattered signal intensity varied greatly with the opening area of the pulsed valve. A new method is put forward to choose the appropriate scattered signal and measure the size of Kr cluster.

    1961-12-11

    It is almost sixty years since Emil Fischer was describing on a platform such as this one some of the work which led to the basic knowledge of the structure of glucose and its relatives. Today we will be concerned with a description of the experiments which have led to a knowledge of the principal reactions by which those carbohydrate structures are created by photosynthetic organisms from carbon dioxide and water, using the energy of light. The speculations on the way in which carbohydrate was built from carbon dioxide began not long after the recognition of the basic reaction and were carried forward first by Justus von Liebig and then by Adolf von Baeyer and, finally, by Richard Wilstatter and Arthur Stoll into this century. Actually, the route by which animal organisms performed the reverse reaction, that is, the combustion of carbohydrate to carbon dioxide and water with the utilization of the energy resulting from this combination, turned out to be the first one to be successfully mapped, primarily by Otto Meyerhoi and Hans Krebs. Our own interest in the basic process of solar energy conversion by green plants began some time in the years between 1935 and 1937, during my postdoctoral studies with Professor Michael Polanyi at Manchester. It was there I first became conscious of the remarkable properties of coordinated metal compounds, particularly metalloporphyins as represented by heme and chlorophyll. A study was begun at that time, which is still continuing, on the electronic behavior of such metalloporphyrins. It was extended and generalized by the stimulus of Professor Gilbert N. Lewis upon my arrival in Berkeley. I hope these continuing studies may one day contribute to the understanding of the precise way in which chlorophyll and its relatives accomplish the primary quantum conversion into chemical potential which is used to drive the carbohydrate synthesis reaction.

    Scalable fabrication of carbon nanotube (CNT) bundles is essential to future advances in several applications. Here, we report on the development of a simple, two-step method for fabricating vertically aligned and periodically distributed CNT bundles and periodically porous CNT films at the sub-micron scale. The method involves laser interference ablation (LIA) of an iron film followed by CNT growth via iron-catalyzed chemical vapor deposition. CNT bundles with square widths ranging from 0.5 to 1.5 µm in width, and 50-200 µm in length, are grown atop the patterned catalyst over areas spanning 8 cm(2). The CNT bundles exhibit a high degree of control over square width, orientation, uniformity, and periodicity. This simple scalable method of producing well-placed and oriented CNT bundles demonstrates a high application potential for wafer-scale integration of CNT structures into various device applications, including IC interconnects, field emitters, sensors, batteries, and optoelectronics, etc.

    This paper is about the Sudbury Neutrino Observatory (SNO) experiment. SNO achieved a major breakthrough on the study of the behavior of an elementary and enigmatic particle of the universe - the neutrino. The experiment was the result of the synthesis of over 30-years of work on particle physics, astrophysics and nuclear science that saw early germination at Chalk River Laboratories. Preliminary SNO results led to a major leap forward on how to measure sub-atomic phenomena that were never used to this extent before and have also provided new insights into the Standard Model of physics, and indeed in our fundamental understanding of the entire universe.

    For many years, Malaysia has been a strong and supportive partner of the IAEA. On the non-proliferation front, Malaysia is party to the NPT, with a comprehensive safeguards agreement in force. In November 2005, Malaysia also signed the additional protocol to its safeguards agreement. In the field of safety, Malaysia is a party to the conventions on early notification and assistance in the case of an accident or radiological emergency. Malaysia also participates in the Asian Nuclear Safety Network. The IAEA has a large and active technical cooperation (TC) programme in Malaysia. For example, the IAEA has been supporting the use of isotope hydrology in Malaysia to combat groundwater contamination in industrial sites. Last year we were also active in the health sector in Malaysia, supporting training and workforce development in the use of positron emission tomography. We are supporting the establishment of a Malaysian cyclotron facility for radioisotope production. The most recent such development was the establishment of a laboratory for the application of radiation in nanotechnology. And Malaysia plays an important role in hosting conferences, workshops and training courses in areas such as non-destructive testing, radiation safety, tissue grafts, regional electronic networking and the maintenance of nuclear instruments. The need to ensure adequate and reliable energy supplies is directly relevant to development, and to national and international security. As such, energy will continue to be an important part of the global agenda for the foreseeable future. Like many countries, Malaysia faces complex choices as it looks to expand its energy mix and ensure its energy security.

    2011-06-15

    The Netherlands has a long history of salt production and salt trade. Since the prohibition of salt production in the year 1515, the Netherlands were dependent on salt imports especially from France, Portugal, Spain and from the Cape Verde Islands. In the 18th century, a two-stage process for extracting salt from sea water was developed. This method consisted of an evaporation of sea water and a subsequent concentration of the brine. In the 19th century, this process (grading) was forbidden because the amount of taxes could not be determined. Therefore, since 1871 The Netherlands were dependent on the import of rock salt from the United Kingdom and Germany. Due to the declining exports of salt, from the year 1900 the Dutch manufactures produced salt only for domestic needs.

    1997-01-01

    The historians of dentistry met two men named Laveran - both with unknown surnames - among the 18th century Parisian "experts" for teeth. Having discovered some notarial documents concerning them, the author was anxious to know more about them and was driven to investigate their possible relationship with Alphonse Laveran, who was born however more than one century later. A special impulse to this research resulted from the fact - learnt from the Lille archives - that Louis Laveran, the grand-father of Alphonse, was born in the same tiny place as one of the two Parisians mentioned above, and was himself a dentist surgeon. At last, the author could identify the ties existing between these Laverans, and collect a lot of informations about their family, from which a selection is given here. In short, the great-great-grand-father of Alphonse was established as a weaver in a small town of the south-West of France (Montesquieu-Volvestre, Haute-Garonne). Among his sons were the two Laverans mentioned above, who became dentist surgeons in Paris. One of them was Pierre Laveran. He was the specialist who was called to straighten the teeth of the young archduchess Marie-Antoinette, before her wedding with the future Louis XVI, in 1770. Then he was appointed as the dentist surgeon of Their Imperial and Royal Majesties in Vienna. Married with Anna Theresia Peska, he died there in 1796, leaving four children born between 1781 and 1787. ...

For the first time, GNRs were successfully assembled on the surfaces of GO by means of electrostatic interactions without adding any surfactant. The SERS properties of GO/AgNPs, GO/GNPs, and GO/GNRs were compared using 2-mercaptopyridine (2-Mpy as probing molecule. We found that GO/AgNPs and GO/GNPs substrates are not suitable for detecting 2-Mpy due to the very strong π-π stacking interaction between the 2-Mpy molecules and sp2 carbon structure of GO. Conversely, the GO/GNRs substrates show ultrahigh SERS activity and sensitivity of 2-Mpy with the detection limit as low as ~10-15 M, which is ~2-3 orders of magnitude higher than that of the corresponding GNRs.

    This conference begins with a personal evocation of the author's grandfather, Gaspar Cruz y Martín, Anatomic Sculptor at the Faculty of Medicine of San Carlos--the commemorative medal depicting Cajal that can be seen today at the Cajal Teaching Room Museum in the Medical College of Madrid is due to his hand. The talk goes on to compile a little anthology of texts on women by Cajal, chosen as literary counterparts to his scientific writings. Women are seen by Cajal under the light of beauty, love, marriage, family and even feminism. The anthology ends with a series of "misogynistic stings"--as Dr. Cruz y Hermida calls them--which alternate negative criticism with open praise, mostly showing the admiration that women caused in the sensitive intelligence of the great humanist. The conference finishes with an account of the last moments of Cajal and the moving words by D. Teófilo Hernando, who was at the side of the Maestro when he passed away.

    Bose-Einstein condensation, or BEC, has a long and rich history dating from the early 1920s. In this article we will trace briefly over this history and some of the developments in physics that made possible our successful pursuit of BEC in a gas. We will then discuss what was involved in this quest. In this discussion we will go beyond the usual technical description to try and address certain questions that we now hear frequently, but are not covered in our past research papers. These are questions along the lines of: How did you get the idea and decide to pursue it? Did you know it was going to work? How long did it take you and why? We will review some our favorites from among the experiments we have carried out with BEC. There will then be a brief encore on why we are optimistic that BEC can be created with nearly any species of magnetically trappable atom. Throughout this article we will try to explain what makes BEC in a dilute gas so interesting, unique, and experimentally challenging

    Transition-metal-catalyzed diazo activation is a classical way to generate metal carbene, which are valuable intermediates in synthetic organic chemistry. An alternative iodine-catalyzed diazo activation is disclosed herein under either photo-initiated or thermal-initiated conditions, which represents an approach to enable carbene radical reactivity. This metal-free diazo activation strategy were successfully applied into olefin cyclopropanation and epoxidation, and applying this method to pyrrole synthesis under thermal-initiated conditions further demonstrates the unique reactivity using this method over typical metal-catalyzed conditions.

    In this invited Perspective, I provide a personal account highlighting several of my group's research contributions in metallo-organic chemistry over the past 40 years. Our early work focused primarily in stoichiometric structure/reactivity of transition metal-organic compounds and their use in organic synthesis. More recent efforts have centered on the discovery and development of new metal-catalyzed organic reactions via reactive metal-organic intermediates. The major research findings that are described here include (1) propargyl-cobalt complexes as electrophilic agents for C-C and C-Nu coupling; (2) the activation of carbon dioxide by metal complexes; (3) metal-promoted C-H nitrogenation reactions; (4) oxo-metal catalyzed deoxygenation reactions; and (5) catalyst discovery via dynamic templating with substrate- and transition-state analogues.

    Cycloaddition reactions are among the most important tools for synthesis in organic chemistry, since these reactions are vital to the modern synthesis of natural products and biologically active substances. Metal catalysis plays an increasingly important role in these reactions, often allowing several stereocenters to be selectively created and integrated in the target molecules. Kobayashi and Jorgensen's handbook provides numerous examples of metal-catalyzed reactions, including [2+1], [3+2] and [4+2] cycloadditions. Important reactions such as carbo- and hetero-Diels-Alder, carbocyclic, cyclopropanation and 1,3-dipolar cycloaddition reactions are discussed. A large number of experimental procedures gives a concrete idea of the use of metal-catalyzed cycloaddition reactions in modern synthesis. The book is aimed at chemists in industry or academia, who want to effectively use cycloadditions in their work.

    2015-04-13

    The total hydrodeoxygenation of carbohydrate-derived molecules to alkanes, a key reaction in the production of biofuel, was reviewed from the aspect of catalysis. Noble metals (or Ni) and acid are the main components of the catalysts, and group 6 or 7 metals such as Re are sometimes added as modifiers of the noble metal. The main reaction route is acid-catalyzed dehydration plus metal-catalyzed hydrogenation, and in some systems metal-catalyzed direct CO dissociation is involved. The appropriate active metal, acid strength, and reaction conditions depend strongly on the reactivity of the substrate. Reactions that use Pt or Pd catalysts supported on Nb-based acids or relatively weak acids are suitable for furanic substrates. Carbohydrates themselves and sugar alcohols undergo CC dissociation easily. The systems that use metal-catalyzed direct CO dissociations can give a higher yield of the corresponding alkane from carbohydrates and sugar alcohols. © 2015 WILEY-VCH Verlag GmbH & Co.

    Palladium-catalysed cross-couplings, in particular Heck, Suzuki-Miyaura and Negishi reactions developed over three decades ago, are routinely carried out in organic solvents. However, alternative media are currently of considerable interest given an increasing emphasis on making organic processes 'greener'; for example, by minimising organic waste in the form of organic solvents. Water is the obvious leading candidate in this regard. Hence, this review focuses on the application of micellar catalysis, in which a 'designer' surfactant enables these award-winning coupling reactions to be run in water at room temperature.

    The selective laser melting (SLM) technique is a recent additive manufacturing (AM) technique. Several studies have reported success in the SLM-based production of biocompatible orthopaedic implants and three-dimensional bone defect constructs. In this study, we evaluated the surface properties and biocompatibility of an SLM titanium implant in vitro and compared them with those of a machined (MA) titanium control surface. In addition, we evaluated the osseointegration capability of the SLM implants in vivo and compared it with those of MA and Nobel-speedy (Nobel-S) implants. SLM microtopographical surface analysis revealed porous and high roughness with varied geometry compared with a smooth surface in MA Ti samples but with similar favourable wettability. Osteoblast proliferation and alkaline phosphatase activity were significantly enhanced on the SLM surface. Histological analysis of the bone-implant contact ratio revealed no significant difference among SLM, MA, and Nobel-S implants. Micro-CT assessment indicated that there was no significant difference in bone volume fraction around the implant among SLM implants and other types of surface modification implants. The removal torque value measurement of SLM implants was significantly lower that of than Nobel-S implants P manufacturing technique.
