20-Aug-2015 Carbon number crunching
A booming economy and population led China to emerge in 2006 as the global leader in fossil-fuel carbon emissions, a distinction it still maintains. But exactly how much carbon China releases has been a topic of debate, with recent estimates varying by as much as 15 percent.
18-Aug-2015 Viral comparisons
An Oak Ridge National Laboratory team of comparative genomics and computational science researchers compared approximately 4,000 complete virus genomes downloaded from a public database known as GenBank.

Recently, the Department of Energy Office of Science's Nanoscale Science Research Centers at Argonne, Brookhaven, Lawrence Berkeley, Los Alamos/Sandia and Oak Ridge national laboratories jointly organized a workshop at Oak Ridge National Laboratory to discuss opportunities and challenges as imaging and data sciences merge. Those efforts will likely aid the Materials Genome Initiative, which aims to speed new materials to the global marketplace.
7-Aug-2015 New Brookhaven summer course introduces high school students to scientific computing
19 Long Island high school students completed a two-week workshop designed to teach them the basics of computer programming for scientific research. With this new program, the US Department of Energy's (DOE) Brookhaven National Laboratory looks to use its resources to begin to fill a gap in public science education while also building a pipeline to help identify and train the computer-literate researchers of tomorrow.
7-Aug-2015 Unique SLAC technology to power X-ray laser in South Korea
Accelerator technology pioneered at the Department of Energy's SLAC National Accelerator Laboratory is on its way to powering X-ray science in South Korea: On Aug. 6, the lab shipped one of its unique radio-frequency amplifiers -- an XL4 klystron -- to Pohang Accelerator Laboratory, where it will become a key component for the optimal performance of a new X-ray free-electron laser under construction.
5-Aug-2015 SLAC builds one of the world's fastest 'electron cameras'
A new scientific instrument at the Department of Energy's SLAC National Accelerator Laboratory promises to capture some of nature's speediest processes. It uses a method known as ultrafast electron diffraction (UED) and can reveal motions of electrons and atomic nuclei within molecules that take place in less than a tenth of a trillionth of a second -- information that will benefit groundbreaking research in materials science, chemistry and biology.
31-Jul-2015 Magnetism at nanoscale
As the demand grows for ever smaller, smarter electronics, so does the demand for understanding materials' behavior at ever smaller scales. Physicists at the US Department of Energy's Ames Laboratory are building a unique optical magnetometer to probe magnetism at the nano- and mesoscale.
28-Jul-2015 Rigors of the road: ORNL invention will support licensing and transport of spent nuclear fuel
With support from the US Nuclear Regulatory Commission, researchers at the Department of Energy's Oak Ridge National Laboratory have devised the Cyclic Integrated Reversible-bending Fatigue Tester. Combined with ongoing fuel transportation research, data from the CIRFT system will help facilitate cask designs and transportation protocols that ensure safe transportation of spent nuclear fuel.
27-Jul-2015 Brookhaven Lab summer school helps develop tomorrow's nuclear chemistry experts
For the past six weeks, 12 college students have had the opportunity to learn all that the US Department of Energy's (DOE) Brookhaven National Laboratory has to teach about a vital but often overlooked area of chemistry -- one that spans everything from nuclear reactors and the safe handling of nuclear material to hospital diagnostic tools and cutting-edge medical research.
22-Jul-2015 Whole lotta shakin' goin' on
It took decades for technology to catch up with the math David Smallwood worked out to control vibration table shakers. Smallwood, a retired Sandia National Laboratories researcher who consults at the labs, knew that shaking in all directions at once was the key to realistic parts testing. Now Sandia is putting the algorithms he developed more than 30 years ago to the test.
7-Jul-2015 Big PanDA and Titan merge to tackle torrent of LHC's full-energy collision data
With the successful restart of the Large Hadron Collider, now operating at nearly twice its former collision energy, comes an enormous increase in the volume of data physicists must sift through to search for new discoveries. Fortunately, a remarkable data-management tool developed by physicists at Brookhaven National Laboratory and the University of Texas at Arlington is evolving to meet the big-data challenge.
6-Jul-2015 Scientists drive tiny shock waves through diamond
Researchers have used an X-ray laser to record, in detail never possible before, the microscopic motion and effects of shock waves rippling across diamond. The technique, developed at the Department of Energy's SLAC National Accelerator Laboratory, allows scientists to precisely explore the complex physics driving massive star explosions, which are critical for understanding fusion energy, and to improve scientific models used to study these phenomena.
6-Jul-2015 Upgrades to ATLAS and LHC magnets for Run 2 and beyond
At the beginning of June, the Large Hadron Collider at CERN, the European research facility, began smashing together protons once again. Physicists at Brookhaven National Laboratory were busy throughout Long Shutdown 1, undertaking projects designed to maximize the LHC's chances of detecting rare new physics as the collider reaches into a previous unexplored subatomic frontier.
30-Jun-2015 Homegrown solution for synchrotron light source
Scientists at the US Department of Energy's Ames Laboratory have made advances in angle-resolved photoemission spectroscopy (ARPES) to help better study electronic properties of new materials.
29-Jun-2015 Magnetic attraction
Researchers studying a broad spectrum of science, including biofuel production processes, climate effects on carbon cycling in the soil and carbon transformations in the atmosphere will soon have access to EMSL's new 21 Tesla Fourier transform ion cyclotron resonance mass spectrometer. Scientists are eager to start getting molecular-level information for their research, and six inaugural studies were selected to use the new instrument through a Special Science Call.
24-Jun-2015 Berkeley Lab scientists to develop better way to screen chemicals for cancer-causing effects
Berkeley Lab scientists are developing a cell culture that could help researchers better identify chemicals that increase breast cancer susceptibility. The scientists will grow the culture using adult stem cells obtained from breast tissue. Their test will show if a chemical causes a breakdown in cell-to-cell communication, a fundamental defect of cancer.
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.
