15-Jan-2015 RHIC physics feeds future high-tech workforce: Ágnes Mócsy
Ágnes Mócsy, a theoretical physicist and tenured associate professor at Pratt Institute, one of the world's prestigious art and design universities, hopes to convey the sense of awe she experienced seeing Brookhaven Lab's particle collider to the art students she teaches in physics and astronomy classes for non-physics majors.
12-Jan-2015 Water, water, everywhere -- Controlling the properties of nanomaterials
Properties of water molecules on the surface of metal oxides can be used to better control these minerals and use them to make products such as more efficient semiconductors for organic light emitting diodes and solar cells, safer vehicle glass in fog and frost, and more environmentally friendly chemical sensors for industrial applications.
5-Jan-2015 2014's top-10 scientific achievements at Brookhaven Lab
From new insights into the building blocks of matter to advances in understanding batteries, superconductors, and a protein that could help fight cancer, 2014 was a year of stunning successes for the US Department of Energy's Brookhaven National Laboratory.
18-Dec-2014 Crown ethers flatten in graphene for strong, specific binding
A team led by the Department of Energy's Oak Ridge National Laboratory has discovered a way to dramatically increase the selectivity and binding strength of crown ethers by incorporating them within a rigid framework of graphene. Strong, specific electrostatic binding of crown ethers may advance sensors, chemical separations, nuclear-waste cleanup, extraction of metals from ores, purification and recycling of rare-earth elements, water purification, biotechnology, energy production in durable lithium-ion batteries, catalysis, medicine and data storage.
15-Dec-2014 Is the Higgs Boson a piece of the matter-antimatter puzzle?
Several experiments, including the BaBar experiment at the Department of Energy's SLAC National Accelerator Laboratory, have helped explain some -- but not all -- of the imbalance between matter and antimatter in the universe. Now a SLAC theorist and his colleagues have laid out a possible method for determining if the Higgs boson is involved.
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.
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
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.
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.
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.
