4-Sep-2014 Scientists map protein in living bacterial cells
Scientists have for the first time mapped the atomic structure of a protein within a living cell. The technique, which peered into cells with an X-ray laser, could allow scientists to explore some components of living cells as never before. The research, published Aug. 18 in Proceedings of the National Academy of Sciences, was conducted at the Department of Energy's SLAC National Accelerator Laboratory.
2-Sep-2014 Researcher wins x-ray science award for SSRL work aiding chemistry studies
Chris Pollock, a postdoctoral researcher at The Pennsylvania State University, whose research at the Department of Energy's SLAC National Accelerator Laboratory was key in adapting an X-ray technique to probe chemical bonds in new ways, has been named the latest recipient of an annual scientific award.
28-Aug-2014 Materials scientists play atomic 'Jenga' and make a surprising discovery
Researchers got a surprise when they built a highly ordered lattice by layering thin films containing lanthanum, strontium, oxygen and iron. Although each layer had an intrinsically nonpolar (symmetric) distribution of electrical charges, the lattice had an asymmetric distribution of charges. The charge asymmetry creates an extra 'switch' that brings functionalities to materials when 'flipped' by external stimuli. The material defects induced polar behavior and can provide a new mechanism for manipulating electricity and magnetism in energy and information technologies.
22-Aug-2014 Catalytic gold nanoclusters promise rich chemical yields
With scientists from Carnegie Mellon University, researchers at the Department of Energy's Oak Ridge National Laboratory have found a catalyst containing exactly 25 gold atoms that catalyzes the conversion of various molecules, including the transformation of poisonous carbon monoxide into harmless carbon dioxide, a reaction that may find application in devices near gas flues or wood-burning stoves.
20-Aug-2014 Junior researchers showing world the way to advanced nuclear fuel design
Two early-career Idaho National Laboratory researchers are earning international attention for their groundbreaking work. They're getting a long-sought look into the 3-D microstructure of irradiated nuclear fuel, then feeding that data into cutting-edge fuel behavior models. Their work will make the design and testing of even safer nuclear fuels more informed and efficient.
20-Aug-2014 SLAC summer institute students take a close look at dark matter
Physicists have good reason to believe 85 percent of the matter in the universe is currently undetectable. But not being able to see it didn't keep students at the 42nd SLAC Summer Institute, held at the Department of Energy's SLAC National Accelerator Laboratory, from learning about it.
20-Aug-2014 Ying Diao honored with 2014 Spicer Award for her work at SSRL
Ying Diao, a SLAC/Stanford postdoctoral researcher who brought key innovations to a printing technique for flexible electronics, solar panels and other uses, has been selected to receive this year's William E. and Diane M. Spicer Young Investigator Award.
18-Aug-2014 Berkeley Lab's SPOT Suite transforms beamline science
For decades, synchrotron light sources have been operating on a manual grab-and-go data management model, but a recent deluge of data is quickly making this practice implausible. So Berkeley Lab X-ray scientists, facility users, computer and computational scientists, teamed up to create new tools for reducing, managing, analyzing and visualizing beamline data.The result of this collaboration is SPOT Suite, and it is already transforming the way scientists run their experiments at the ALS.
31-Jul-2014 Giant electromagnet completes its journey, moves into its new home at Fermilab
One year ago, the 50-foot-wide Muon g-2 electromagnet arrived at the US Department of Energy's Fermi National Accelerator Laboratory in Illinois after traveling 3,200 miles over land and sea from Long Island, N.Y. This week, the magnet took the final few steps of that journey, moving across the Fermilab site and into the new building that now houses it.
22-Jul-2014 Sandia ensures US nuclear weapons deterrent can remain effective, credible
As part of its mission of ensuring the nation's stockpile is safe, secure and effective as a deterrent, Sandia National Laboratories must make sure crucial parts can function if they're hit by radiation, especially a type called fast neutrons. It created a science-based program called QASPR, which combines computer modeling and simulation, and experiments and technology development.
17-Jul-2014 Hot plasma partial to bootstrap current
Supercomputers at NERSC are helping plasma physicists 'bootstrap' a potentially more affordable and sustainable fusion reaction. If successful, fusion reactors could provide almost limitless clean energy.
15-Jul-2014 Ames Laboratory home to first-in-nation DNP-NMR instrument to study materials
The US Department of Energy's Ames Laboratory is now the home to a dynamic nuclear polarization (DNP) solid-state nuclear magnetic resonance (NMR) spectrometer that helps scientists understand how individual atoms are arranged in materials. Ames Laboratory's DNP-NMR is the first to be used for materials science and chemistry in the United States.
15-Jul-2014 Physicists detect process even rarer than the long-sought Higgs particle
Scientists running the ATLAS experiment at the Large Hadron Collider (LHC), the world's largest and most powerful 'atom smasher,' report the first evidence of a process that can be used to test the mechanism by which the recently discovered Higgs particle imparts mass to other fundamental particles.
14-Jul-2014 First anniversary gift for Critical Material Institute? Inventions. Eleven of them.
The Critical Materials Institute, an Energy Innovation Hub for the US Department of Energy, celebrated its first anniversary with 11 invention disclosures, all research milestones in a mission to assure the availability of rare earths and other materials critical to clean energy technologies.
The inventions include improved extractive processes, recycling techniques, and substitute materials -- technologies designed to increase production and efficiency of, and reduce reliance on, the use of rare earths and other critical materials.
25-Jun-2014 Massive 30-ton MicroBooNE particle detector moved into place, will see neutrinos this year
On Monday, June 23, the next phase of neutrino physics at Fermilab fell (gently) into place.
The MicroBooNE detector -- a 30-ton, 40-foot-long cylindrical metal tank designed to detect ghostly particles called neutrinos -- was carefully transported by truck across the US Department of Energy's Fermilab site, from the warehouse building it was constructed in to the experimental hall three miles away.
25-Jun-2014 A model for success
Idaho National Laboratory researcher Blaise Collin works with software called PARFUME (particle fuel model) as part of an effort to find new, safer fuel sources for use in nuclear reactors.
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.
