4-Dec-2014 X-ray laser reveals how bacterial protein morphs in response to light
Researchers have captured the highest-resolution snapshots ever taken with an X-ray laser that show changes in a protein's structure over time, revealing how a key protein in a photosynthetic bacterium changes shape when hit by light. They achieved a resolution of 1.6 angstroms, equivalent to the radius of a single tin atom.
4-Dec-2014 Rattled atoms mimic high-temperature superconductivity
An experiment at the Department of Energy's SLAC National Accelerator Laboratory provided the first fleeting glimpse of the atomic structure of a material as it entered a state resembling room-temperature superconductivity -- a long-sought phenomenon in which materials might conduct electricity with 100 percent efficiency under everyday conditions.
3-Dec-2014 SLAC, RadiaBeam build new tool to tweak rainbows of X-ray laser light
The Department of Energy's SLAC National Accelerator Laboratory has teamed up with Santa Monica-based RadiaBeam Systems to develop a device known as a dechirper, which will provide a new way of adjusting the range of energies within single pulses from SLAC's X-ray laser.
1-Dec-2014 Optimized algorithms boost combustion research
Turbulent combustion simulations, used in the design of more fuel-efficient combustion systems, have gotten their own efficiency boost, thanks to researchers from Berkeley Lab's Computational Research Division. They developed new algorithmic features that streamline turbulent flame simulations, which are commonly used in the design of combustion systems such as diesel engines; after testing the enhanced code on NERSC supercomputers, they were able to achieve dramatic improvements in simulation times, which will help reduce the time -- and thus the cost -- of designing new engines.
24-Nov-2014 Berkeley Lab algorithms help researchers understand dark energy
To unlock the mystery of dark energy and its influence on the universe, researchers must rely on indirect observations -- watching how fast Type Ia supernovae recede from us as the universe expands. The process of identifying and tracking these objects requires scientists to scrupulously monitor the night sky for slight changes, a task that would be tedious and time-consuming for the Dark Energy Survey without novel tools developed by Berkeley Lab and UC Berkeley researchers.
21-Nov-2014 Robotics meet X-ray lasers in cutting-edge biology studies
Scientists at the Department of Energy's SLAC National Accelerator Laboratory are combining the speed and precision of robots with one of the brightest X-ray lasers on the planet for pioneering studies of proteins important to biology and drug discovery.
21-Nov-2014 President Obama bestows National Medal of Science on SLAC director emeritus Burton Richter
President Barack Obama presented SLAC director emeritus and Nobel Prize winner Burton Richter with the National Medal of Science at a Nov. 20 ceremony at the White House. Richter was one of 10 distinguished researchers presented with the National Medal of Science, the highest honor for achievement and leadership in advancing the field of science.
20-Nov-2014 Agreement gives energy storage companies easier access to SLAC
More than a dozen energy-storage companies now have streamlined access to research facilities and expertise at the Department of Energy's SLAC National Accelerator Laboratory under a new cooperative research and development agreement, or CRADA.
19-Nov-2014 Fast company
Researchers answering fundamental scientific questions in biology, climate and chemistry look to high performance computing and robust software. With its history of integrating experiment and computation, EMSL supports research into climate change, contaminated soil remediation, and energy production and storage with its Cascade supercomputer and enhanced NWChem computational chemistry software.
17-Nov-2014 Spiraling back in time
Using a code developed for GPU supercomputing architectures, including that of the Department of Energy's Oak Ridge National Laboratory's Cray XK7 Titan, to simulate the evolution of the Milky Way galaxy, a team of researchers from the Netherlands and Japan is a Gordon Bell Prize finalist.
13-Nov-2014 SUNCAT director Jens Nørskov awarded 2015 Langmuir Prize
Jens NÝrskov, a professor at Stanford University and the Department of Energy's SLAC National Accelerator Laboratory, will receive the 2015 Irving Langmuir Prize of the American Physical Society for his groundbreaking work on catalysis, which is used to promote chemical reactions in thousands of industrial processes for making fertilizers, fuels, plastics and a host of other products.
11-Nov-2014 Researchers take snapshots of potential 'kill switch' for cancer
A study conducted in part at the Department of Energy's SLAC National Accelerator Laboratory has revealed how a key human protein switches from a form that protects cells to a form that kills them -- a property that scientists hope to exploit as a 'kill switch' for cancer.
22-Oct-2014 SLAC steps up to the plate at Bay Area Science Festival
The Department of Energy's SLAC National Accelerator Laboratory will once again participate as an exhibitor in Discovery Days at AT&T Park on Saturday, Nov. 1, from 11 a.m. to 4 p.m. The concluding highlight of the fourth annual 10-day Bay Area Science Festival -- which is free and open to the public -- will transform the home of the San Francisco Giants into a science wonderland with activities for kids ages 0 to 14.
22-Oct-2014 Brookhaven Lab launches Computational Science Initiative
NY-Building on its capabilities in computational science and data management, the US Department of Energy's Brookhaven National Laboratory is embarking upon a major new Computational Science Initiative. This program will leverage computational science expertise and investments across multiple programs at the Laboratory-including the flagship facilities that attract thousands of scientific users each year-further establishing Brookhaven as a leader in tackling the 'big data' challenges at the frontiers of scientific discovery.
20-Oct-2014 Puzzling new behavior found in high-temperature superconductors
Research by an international team led by SLAC and Stanford scientists has uncovered a new, unpredicted behavior in a copper oxide material that becomes superconducting -- conducting electricity without any loss -- at relatively high temperatures.
17-Oct-2014 Atomic trigger shatters mystery of how glass deforms
A new study at the Department of Energy's Oak Ridge National Laboratory, published Sept. 24 in Nature Communications, has cracked one mystery of glass to shed light on the mechanism that triggers its deformation before shattering. The study improves understanding of glassy deformation and may accelerate broader application of metallic glass, a moldable, wear-resistant, magnetically exploitable material that is thrice as strong as the mightiest steel and ten times as springy.
The Department of Energy'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.
