Science Beat: Scientific Computing Group Works Toward Crystallization in Silico

The workhorse for solving the structures of biological molecules is x-ray crystallography, but some proteins can't be crystallized. Enter single-particle electron cryomicroscopy, a technique that uses images of randomly oriented molecules, frozen in solution, to construct a 3-D model in the computer. The technique uses algorithms developed by Chao Yang and Esmond Ng of CRD's Scientific Computing Group in collaboration with Bob Glaeser, a member of Berkeley Lab's Life Sciences and Physical Biosciences Divisions. Read the article by Paul Preuss at http://www.lbl.gov/Science-Articles/Archive/sb/Nov-2004/01-crystallization.html.

David Bailey's New Math Book Reviewed as Must-Have for Mathematicians

The second volume in a two-volume set on experimental math co-authored by David Bailey is so valuable that "every mathematics library requires a copy of this book," according to an online review posted by the American Mathematical Society.  The book, "Mathematics by Experiment. Plausible Reasoning in the 21st Century," was co-written with Jonathan Borwein. The book, published this year, is a companion volume to "Experimentation in Mathematics" published in 2003. The full review, which appeared on MathSciNet, can be read at http://www.cs.dal.ca/~jborwein/mr-mbye.pdf.

Bailey and Borwein will be invited speakers at HPCS2005, the 19th international symposium on high performance computing systems and applications, to be held next May in Ontario, Canada.

Livermore Lab's Jeanie Larson to Speak at Dec. 9 Computer Protection Brown Bag

Jeanie Larson, Livermore Lab's incident response manager, will speak at the next Computer Protection Brown Bag Event at noon Thursday, Dec. 9, in 50D-3416 (the Bldg. 50D conference room). The topic will be "Wireless Security for the End User: Truths and Myths."

About Computing Sciences at Berkeley Lab

The Lawrence Berkeley National Laboratory (Berkeley Lab) Computing Sciences organization provides the computing and networking resources and expertise critical to advancing the Department of Energy's research missions: developing new energy sources, improving energy efficiency, developing new materials and increasing our understanding of ourselves, our world and our universe.

ESnet, the Energy Sciences Network, provides the high-bandwidth, reliable connections that link scientists at 40 DOE research sites to each other and to experimental facilities and supercomputing centers around the country. The National Energy Research Scientific Computing Center (NERSC) powers the discoveries of 7,000-plus scientists at national laboratories and universities, including those at Berkeley Lab's Computational Research Division (CRD). CRD conducts research and development in mathematical modeling and simulation, algorithm design, data storage, management and analysis, computer system architecture and high-performance software implementation. NERSC and ESnet are Department of Energy Office of Science User Facilities.

Lawrence Berkeley National Laboratory addresses the world's most urgent scientific challenges by advancing sustainable energy, protecting human health, creating new materials, and revealing the origin and fate of the universe. Founded in 1931, Berkeley Lab's scientific expertise has been recognized with 13 Nobel prizes. The University of California manages Berkeley Lab for the DOE’s Office of Science.

DOE’s Office of Science is the single largest supporter of basic research in the physical sciences in the United States, and is working to address some of the most pressing challenges of our time. For more information, please visit science.energy.gov.
