Computer Chemists Win Nobel Prize BBC News - Computer chemists win Nobel prize http://www.bbc.co.uk/news/science-environment-24458534 SCIENCE & ENVIRONMENT 9 October 2013 Last updated at 11:36 Computer chemists win Nobel prize By James Morgan and Jonathan Amos Science reporters, BBC News The Nobel Prize in chemistry has gone to three scientists who "took the chemical experiment into cyberspace". Michael Levitt, a British-US citizen of Stanford University; US-Austrian Martin Karplus of Strasbourg University; and US-Israeli Arieh Warshel of the University of Southern California will share the prize. The trio devised computer simulations to understand chemical processes. In doing so, they laid the foundations for new kinds of pharmaceuticals. Today, scientists routinely use modelling to understand how different biological molecules interact, to probe the mechanisms of disease and to design novel drugs. "The Nobel Laureates in Chemistry 2013 have made it possible to map the mysterious ways of chemistry by using computers," said the Royal Swedish Academy of Sciences. "Today the computer is just as important a tool for chemists as the test tube. "Detailed knowledge of chemical processes makes it possible to optimise catalysts, 1 of 4 31/10/2013 12:03 BBC News - Computer chemists win Nobel prize http://www.bbc.co.uk/news/science-environment-24458534 drugs and solar cells." New medicines Warshel told a news conference in Stockholm by telephone that he was "extremely happy" to be woken in the middle of the night in Los Angeles to find out he had won the prize. "In short, what we developed is a way for computers to take the structure of a protein and then to eventually understand how exactly it does what it does," he told reporters. Marinda Li Wu, president of the American Chemical Society, said the award was "very exciting". "The winners have laid the groundwork for linking classic experimental science with theoretical science through computer models. "The resulting insights are helping us develop new medicines; for example, their work is being used to determine how a drug could interact with a protein in the body to treat disease." Martyn Poliakoff, vice-president of Britain's Royal Society, said the award was "important recognition" for a major advance in theoretical chemistry. "Their novel approach combined both classical and quantum physics, and now enables us to understand how very large molecules react," he explained. "This prize highlights the increasing role that theoretical and computational chemistry are playing in this area of science." All three men spent varying periods at the Laboratory of Molecular Biology in Cambridge, UK. Michael Levitt started his PhD at the Medical Research Council facility at the end of the 1960s. Dr Richard Henderson, a current LMB scientist, said the trio's work was hugely important. "They came at it from different angles but with a common goal," he told BBC News. 2 of 4 31/10/2013 12:03 BBC News - Computer chemists win Nobel prize http://www.bbc.co.uk/news/science-environment-24458534 "They developed computer mathematical models for the forces that hold together mainly proteins, but other biological structures as well. They listed all the forces between atoms, and then they put these into one big computer program and set it running. "In this way, they could simulate in the computer the behaviour of real proteins as they folded and unfolded, as they bind substrates and ligands. "They were really the first people to push this field forward, and today it has become a worldwide industry." Michael Levitt himself said this success was due in large part to the spectacular performance of modern computing: "I've told people that the silent partner in this prize is the incredible development in computer power. "When we started this, no-one had any clue that computers were going to become so powerful; no-one knew about Moore's Law. "This incredible increase in computer power has taken everybody by surprise, and I think this is one of the reasons why our field has become so important. And it's just going to get bigger and bigger."

    Molecular geometry and molecular graphics: Natta's polypropylene and beyond Guido Raos Dip. di Chimica, Materiali e Ing. Chimica \G. Natta", Politecnico di Milano Via L. Mancinelli 7, 20131 Milano, Italy [email protected] Abstract. In this introductory lecture I will try to summarize Natta's contribution to chemistry and materials science. The research by his group, which earned him the Noble prize in 1963, provided unprece- dented control over the synthesis of macromolecules with well-defined three-dimensional structures. I will emphasize how this structure is the key for the properties of these materials, or for that matter for any molec- ular object. More generally, I will put Natta's research in a historical context, by discussing the pervasive importance of molecular geometry in chemistry, from the 19th century up to the present day. Advances in molecular graphics, alongside those in experimental and computational methods, are allowing chemists, materials scientists and biologists to ap- preciate the structure and properties of ever more complex materials. Keywords: molecular geometry, stereochemistry, chirality, polymers, self-assembly, Giulio Natta To be presented at the 18th International Conference on Geometry and Graphics, Politecnico di Milano, August 2018: http://www.icgg2018.polimi.it/ 1 Introduction: the birth of stereochemistry Modern chemistry was born in the years spanning the transition from the 18th to the 19th century. Two key figures were Antoine Lavoisier (1943-1794), whose em- phasis on quantitative measurements helped to transform alchemy into a science on an equal footing with physics, and John Dalton (1766-1844), whose atomic theory provided a simple rationalization for the way chemical elements combine with each other to form compounds.

    Cambridge's 92 Nobel Prize winners part 4 - 1996 to 2015: from stem cell breakthrough to IVF By Cambridge News | Posted: February 01, 2016 Some of Cambridge's most recent Nobel winners Over the last four weeks the News has been rounding up all of Cambridge's 92 Nobel Laureates, which this week comes right up to the present day. From the early giants of physics like JJ Thomson and Ernest Rutherford to the modern-day biochemists unlocking the secrets of our genome, we've covered the length and breadth of scientific discovery, as well as hugely influential figures in economics, literature and politics. What has stood out is the importance of collaboration; while outstanding individuals have always shone, Cambridge has consistently achieved where experts have come together to bounce their ideas off each other. Key figures like Max Perutz, Alan Hodgkin and Fred Sanger have not only won their own Nobels, but are regularly cited by future winners as their inspiration, as their students went on to push at the boundaries they established. In the final part of our feature we cover the last 20 years, when Cambridge has won an average of a Nobel Prize a year, and shows no sign of slowing down, with ground-breaking research still taking place in our midst today.

    Multiscale Modeling of Biological Functions: From Enzymes to Molecular Machines Nobel Lecture, 8 December 2013 by Arieh Warshel University of Southern California, Los Angeles, CA, USA. ABSTRAct A detailed understanding of the action of biological molecules is a prerequisite for rational advances in health sciences and related fields. Here, the challenge is to move from available structural information to a clear understanding of the underlying function of the system. In light of the complexity of macromolecu- lar complexes, it is essential to use computer simulations to describe how the molecular forces are related to a given function. However, using a full and reli- able quantum mechanical representation of large molecular systems has been practically impossible. The solution to this (and related) problems has emerged from the realization that large systems can be spatially divided into a region where the quantum mechanical description is essential (e.g. a region where bonds are being broken), with the remainder of the system being represented on a simpler level by empirical force fields. This idea has been particularly ef- fective in the development of the combined quantum mechanics / molecular mechanics (QM/MM) models. Here, the coupling between the electrostatic ef- fects of the quantum and classical subsystems has been a key to the advances in describing the functions of enzymes and other biological molecules. The same idea of representing complex systems in different resolutions in both time and length scales has been found to be very useful in modeling the action of complex 159 6490_Book.indb 159 11/4/14 2:27 PM 160 The Nobel Prizes systems.

  • Letter from Nobel Laureates
    May 19, 2015 The Honorable Eddie Bernice Johnson Ranking Minority Member Committee on Science, Space and Technology U.S. House of Representatives Washington, DC 20515 Dear Ms. Johnson: We, the undersigned American Nobel laureates in Physics, Chemistry, Medicine and Physiology, urge the House of Representatives to eliminate the separate appropriations authorizations for each directorate in the National Science Foundation when it considers H.R. 1806, The America COMPETES Reauthorization Act of 2015. If the separate authorizations for each directorate are not eliminated, we urge the House to restore the budgets for the Geosciences and Social, Behavioral and Economic Directorates. For the first time in the history of the National Science Foundation, H.R. 1806, as approved by the Committee on Science, Space, and Technology establishes a separate appropriations authorization for each of the Foundation’s directorates. The bill authorizes the appropriation of $1.2 billion annually for the Foundation’s Geosciences Directorate in the next two fiscal years, over $100 million less than this year. The bill authorizes $150 million annually for the Foundation’s Social, Behavioral and Economic Directorate in the next two fiscal years, which is $100 million less than this year. The allocation of funds among the Foundation’s directorates requires a broad understanding of the scientific and engineering opportunities that hold the most promise of advancing scientific and technical knowledge and thus benefiting the nation. The Foundation’s leadership and the scientific and technical experts who advise them are in the best position to make these allocations. The reductions in support for the geosciences and the social sciences contained in H.R.

Background Chemistry and Biochemistry have developed very rapidly during the last 50 years. This applies to all parts of the fields, but the development of Biochemistry is perhaps the most striking one. In the first half of these 50 years the determination of protein structure was perhaps the field where the largest efforts were spent and the largest progress was made. The standard methods to analyse the structure of proteins are X-ray crystallography of crystals or analysing the spin – spin couplings obtained from NMR-spectroscopy.

  • Open Letter to the American People
    FOR IMMEDIATE RELEASE: October 18, 2016 AN OPEN LETTER TO THE AMERICAN PEOPLE The coming Presidential election will have profound consequences for the future of our country and the world. To preserve our freedoms, protect our constitutional government, safeguard our national security, and ensure that all members of our nation will be able to work together for a better future, it is imperative that Hillary Clinton be elected as the next President of the United States. Some of the most pressing problems that the new President will face — the devastating effects of debilitating diseases such as Alzheimer’s disease and cancer, the need for alternative sources of energy, and climate change and its consequences — require vigorous support for science and technology and the assurance that scientific knowledge will inform public policy. Such support is essential to this country’s economic future, its health, its security, and its prestige. Strong advocacy for science agencies, initiatives to promote innovation, and sensible immigration and education policies are crucial to the continued preeminence of the U.S. scientific work force. We need a President who will support and advance policies that will enable science and technology to flourish in our country and to provide the basis of important policy decisions. For these reasons and others, we, as U.S. Nobel Laureates concerned about the future of our nation, strongly and fully support Hillary Clinton to be the President of the United States.
