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.
15-Oct-2014 New directors, new science share spotlight at annual meeting and workshops
Nobel Prize-winning scientists and other prominent researchers, including new directors for the X-ray free-electron laser and synchrotron light sources at the Department of Energy's SLAC National Accelerator Laboratory, led workshops and other scientific presentations at last week's 2014 LCLS/SSRL Annual Users' Meeting and Workshops.
7-Oct-2014 Five years of scientific discoveries with SLAC's LCLS
Five years ago, on the eve of the first X-ray laser experiment at the Department of Energy's SLAC National Accelerator Laboratory, Linda Young summed up her role in leading this inaugural exploration: 'Wow ... Quite an honor, quite a responsibility.'
6-Oct-2014 Study reveals 'bellhops' in cell walls can double as hormones
Researchers have discovered that some common messenger molecules in human cells double as hormones when bound to a protein that interacts with DNA. The finding could bring to light a class of previously unknown hormones and lead to new ways to target diseases -- including cancers and a host of hormone-related disorders.
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 Research pinpoints role of 'helper' atoms in oxygen release
Experiments at the Department of Energy's SLAC National Accelerator Laboratory solve a long-standing mystery in the role calcium atoms serve in a chemical reaction that releases oxygen into the air we breathe. The results offer new clues about atomic-scale processes that drive the life-sustaining cycle of photosynthesis and could help forge a foundation for producing cleaner energy sources by synthesizing nature's handiwork.
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.
17-Sep-2014 Predicting performance
Lignin, a low-cost byproduct of the pulp, paper and biofuels industries, can be transformed into a cheaper version of highly engineered graphite through a simple and industrially scalable manufacturing process.
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.
