14-Mar-2016 Brookhaven Lab named an NVIDIA GPU Research Center
NVIDIA, the world leader in visual computing, has named the US Department of Energy's Brookhaven National Laboratory a 2016 GPU Research Center. Brookhaven Lab was recognized for its use of graphics processing unit (GPU)-accelerated computing to conduct research in fields including materials science, physics, and climate science, and for its vision to further the application of GPU-accelerated computing in those and other research fields with a high computational demand.
9-Mar-2016 ORNL's benchmark data set validates global nuclear reactor codes
A re-analysis of nuclear fuel rods from a commercial reactor used improved radiochemical methods developed at Oak Ridge National Laboratory and characterized more than 50 different isotopes and 16 elements with high accuracy. It produced an experimental data set with uncertainties many times smaller than those obtained by the earlier radiochemical analysis. Modeling and simulation experts at ORNL applied the more accurate experimental data to validate codes widely used by the nuclear safeguards research community.
8-Mar-2016 'Keiser rigs' stress materials to the max to improve products for power, propulsion
For decades, environmental exposure chambers at the Department of Energy's Oak Ridge National Laboratory, including some called Keiser rigs, have subjected materials to corrosive gases, crushing pressures and calamitous heat. The extreme environments created in the Keiser rigs have spurred advances and continue to do so by providing insight into the conditions under which materials fail so researchers can apply the lessons learned to design better materials for power and propulsion applications.
4-Mar-2016 New ways of looking at glass-to-metal seals
Components housed in stainless steel for protection against extreme environments require paths for electricity to power them and communicate with them. Those paths in turn need a reliable insulation seal, so strong bonds between materials for airtight seals are crucial.
3-Mar-2016 Pushing boundaries
Solid-liquid interface studies have a long history at EMSL. The insights gained from this research spans areas including terrestrial ecosystems, energy materials, aerosols and biological systems. With improved understanding of interfacial events, scientists working at EMSL have developed more predictive models and made significant advances in addressing real-world challenges. EMSL's focus on solid-liquid interface research has pushed the development of new instruments and techniques to better study these complex surfaces for even greater scientific results.
25-Feb-2016 Fermilab scientists discover new 4-flavor particle
Scientists on the DZero collaboration at the US Department of Energy's Fermilab have discovered a new particle -- the latest member to be added to the exotic species of particle known as tetraquarks.
22-Feb-2016 Updated workflows for new LHC era
After a massive upgrade, the Large Hadron Collider (LHC) is smashing particles at an unprecedented 13 teraelectronvolts (TeV) -- nearly double the energy of its previous run. In just one second, the LHC can now produce up to 1 billion collisions and generate up to 10 gigabytes of data.
To deal with the new data deluge, researchers working on the LHC's ATLAS experiment are relying on updated workflow management tools developed primarily by Berkeley Lab researchers.
19-Feb-2016 Physicists zoom in on gluons' contribution to proton spin
By analyzing the highest-energy proton collisions at the Relativistic Heavy Ion Collider (RHIC), a particle collider at the US Department of Energy's (DOE) Brookhaven National Laboratory, nuclear physicists have gotten a glimpse of how a multitude of gluons that individually carry very little of the protons' overall momentum contribute to the protons' spin.
19-Feb-2016 New satellite with superior X-ray vision launched
Although the star-covered night sky is regarded by many as a synonym of serenity, the cosmos is in fact a rather hostile place. It hosts many extreme environments that would instantaneously eradicate any life nearby. A new space mission is about to reveal this violent nature in greater detail than ever before: on Feb. 17, the Japan Aerospace Exploration Agency launched its ASTRO-H satellite -- a very precise and sensitive eye for X-rays emerging from hot and energetic processes in space.
17-Feb-2016 Scientists start small on the road to building gigantic DUNE neutrino detector
The planned Deep Underground Neutrino Experiment will require 70,000 tons of liquid argon, making it the largest experiment of its kind -- 100 times larger than the liquid-argon particle detectors that came before it. Before building this unprecedented machine, scientists understandably want to make sure it's going to work. That's why members of the international DUNE collaboration recently began taking data using a test version of their detector.
12-Feb-2016 AWARE project launched to gain new insights on climate of Antarctica
Scientists from Brookhaven National Laboratory, working with a group led by the Scripps Institution of Oceanography, embarked on a new project that will lead to a better understanding of how much of the sun's light and the atmosphere's heat radiation reach the Antarctic surface.
10-Feb-2016 Lynbrook wins second straight SLAC regional Science Bowl
At the annual SLAC Regional DOE Science Bowl on Saturday, Lynbrook High School pulled off a repeat performance of their 2015 win, earning a return trip to the National Science Bowl, which will be held in Washington, D.C., April 28-May 2.
8-Feb-2016 Three ways to bust ghostly dark matter
Dark matter hunters around the world pursue three approaches to look for fingerprints of ghostly WIMPs: on the Earth's surface, underground and in space. Researchers from the Department of Energy's SLAC National Accelerator Laboratory will take part in a discussion of the global search for dark matter particles at this year's AAAS Annual Meeting, to be held Feb. 11-15 in Washington, D.C.
4-Feb-2016 Canfield to head APS Condensed Matter Division
Ames Laboratory physicist Paul Canfield has always been a vocal proponent of his field, condensed matter physics, but he's about to take it up a notch. In March, Canfield will begin a four-year leadership stint heading up the Condensed Matter Physics Division of the American Physical Society. APS recently announced that Canfield had been elected vice-chair of the CMP division.
3-Feb-2016 A mile-deep campus
Students at South Dakota universities can study physics at Sanford Underground Research Facility, which doubles as essentially the first college campus located a mile underground.
29-Jan-2016 Tiniest particles shrink before exploding when hit with SLAC's X-ray laser
Researchers assumed that tiny objects would instantly blow up when hit by extremely intense light from the world's most powerful X-ray laser at the Department of Energy's SLAC National Accelerator Laboratory. But to their astonishment, these nanoparticles initially shrank instead -- a finding that provides a glimpse of the unusual world of superheated nanomaterials that could eventually also help scientists further develop X-ray techniques for taking atomic images of individual molecules.
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.
