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 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

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.
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.
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.
6-Oct-2014 Fermilab's 500-mile neutrino experiment up and running
It's the most powerful accelerator-based neutrino experiment ever built in the United States, and the longest-distance one in the world. It's called NOvA, and after nearly five years of construction, scientists are now using the two massive detectors -- placed 500 miles apart -- to study one of nature's most elusive subatomic particles.
3-Oct-2014 Accelerating the fight against cancer
As charged-particle therapies grow in popularity, physicists are working with other experts to make them smaller, cheaper and more effective -- and more available to cancer patients in the United States.
1-Oct-2014 Brookhaven and the Daya Bay Neutrino Experiment
The Daya Bay Collaboration, an international group of scientists studying the subtle transformations of subatomic particles called neutrinos, is publishing its first results on the search for a so-called sterile neutrino, a particle that could have a profound impact on our understanding of the universe. US Daya Bay Chief Scientist Steve Kettell of Brookhaven National Laboratory offers commentary on the implications of this research.
25-Sep-2014 Breakthrough: Nanote creates more electron beam than large laser system
A collaboration led by RadiaBeam Technologies, a California-based technology firm actively involved in accelerator R&D, is designing an electron beam source that doesn't need a laser. The team led by Luigi Faillace, a scientist at RadiaBeam, is testing a carbon nanotube cathode -- about the size of a nickel -- in Fermilab's High-Brightness Electron Source Lab that completely eliminates the need for a room-sized laser system currently used to generate the electron beam.
24-Sep-2014 Ames Laboratory 3-D printing technology research taking shape
Scientists at the US Department of Energy's Ames Laboratory see amazing potential in 3-D printing and additive manufacturing, and are focusing research toward further advances in the technology. Ames Lab researchers have at their command four experimental 3-D printers that cover a range of unique capabilities.
22-Sep-2014 Ames Laboratory and Japanese R&D organization discuss rare earths
The US Department of Energy's Ames Laboratory and the New Energy and Industrial Technology Development Organization, a Japanese energy and industrial technology research and development organization, held a bilateral meeting on rare-earth materials in Ames on Sept. 10.
18-Sep-2014 Factors underlying nuclear fuel swelling seen at nanoscale for first time
Understanding factors that drive nuclear fuel swelling will help engineers develop higher performance fuels, which could be even safer and more efficient than those used in current nuclear energy plants. As uranium atoms split to produce energy, fission products build up within fuel rods, which impacts nuclear fuel performance inside a reactor. But, a clear picture of the size and location of these solid fission products has been elusive until now.
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.
