30-Jan-2014 Early Edison users deliver results
Before any supercomputer is accepted at NERSC, scientists are invited to put the system through its paces during an "early science" phase. While the main aim of this period is to test the new system, many scientists are able to use the time to significantly advance their work.
29-Jan-2014 NERSC celebrates 40 years at the forefront
This year, the Department of Energy's National Energy Research Scientific Computing Center (NERSC) is celebrating yet another milestone: its 40th anniversary.
29-Jan-2014 Letting in the light
Oak Ridge National Laboratory is developing a low-cost, transparent, anti-soiling coating for solar reflectors to optimize energy efficiency while lowering operating and maintenance costs and avoiding negative environmental impacts.
29-Jan-2014 A map made in the heavens
Researchers supported by the Department of Energy's Office of Science have made an incredibly precise map of the universe to better understand dark energy and other wonders within.
27-Jan-2014 Deployments of network monitoring software perfSONAR hit 1,000
Finding the network bottlenecks that can slow the flow of science data sets and impede research can be extremely complex, especially as such data transfers cross a multitude of linked networks. But perfSONAR, a network monitoring software package developed jointly by DOE's Energy Sciences Network, national labs, universities and Internet 2, is making that task much easier. In January 2014, the number of perfSONAR instances installed in the US and 13 other countries reached 1,000.
16-Jan-2014 Top 10 Brookhaven Lab breakthroughs of 2013
2013 was a banner year for science at the US Department of Energy's Brookhaven National Laboratoryfrom our contributions to Nobel Prize-winning research to new insights into catalysts, superconductors, and other materials key to advancing energy-efficient technologies.
15-Jan-2014 Adding students and multiplying scientists
The Department of Energy's National Science Bowl, an annual event designed to encourage the development of our nation's future leaders in science and technology is set to begin.
7-Jan-2014 The play-by-play of energy conversion: Catching catalysts in action
Before catalysis unfolds in a laboratory, scientists painstakingly assemble the materials and spark a reaction. But many experimental techniques only capture the static details before and after the reaction. Now, researchers at the US Department of Energy's Brookhaven National Laboratory have demonstrated an unprecedented ability to peer into the dynamic, real-time reactions blazing along at scales spanning just billionths of a meter, producing a sort of play-by-play view of the chemistry in action.
6-Jan-2014 Protein puzzles and scientific solutions
Researchers at SLAC National Accelerator Laboratory used powerful new capabilities to -- for the first time -- generate a complete 3-D model of a protein without making use of any previous clue to its structure.
16-Dec-2013 Small size enhances charge transfer in quantum dots
In a study just published in the journal Chemical Communications, scientists at the US Department of Energy's Brookhaven National Laboratory, Stony Brook University, and Syracuse University show that shrinking the core of a quantum dot can enhance the ability of a surrounding polymer to extract electric charges generated in the dot by the absorption of light.
12-Dec-2013 Energetic science and piranha-proof armor
Scientists using Berkeley Lab's Advanced Light Source have identified the unique structure of a tough, flexible and adaptable armor that keeps the Arapaima gigas (a fish) safe in the piranha-infested waters of the Amazon basin.
6-Dec-2013 Tiny drops of hot quark soup -- how small can they be?
New analyses of deuteron-gold collisions at the Relativistic Heavy Ion Collider indicate that collisions between gold ions and much smaller deuterons, designed as control experiments, may be serving up miniscule drops of hot quark-gluon plasma.
29-Oct-2013 NREL brings precision, savings to energy audits
An energy audit tool that more accurately pinpoints potential energy savings while potentially costing 35 percent to 75 percent less than traditional audits is set to hit the multi-billion-dollar energy retrofit industry next year.
17-Oct-2013 Architects and building engineers flock to NREL
Eight busloads of architects and mechanical engineers toured one of the world's largest net-zero-energy office building this summer at the Energy Department's National Renewable Energy Laboratory and came away inspired with new ideas for how to design and build beautiful, eco-friendly structures on a budget.
26-Sep-2013 Supercomputers help solve a 50-year homework assignment
A group of theoretical physicists has solved half of a 50-year homework assignment -- a calculation of one type of subatomic particle decay aimed at helping to answer the question of why the early universe ended up with an excess of matter.
19-Sep-2013 Study could help improve nuclear waste repositories
Sandia National Laboratories researchers are studying the movement of iodine-129 from spent nuclear fuel through a deep, clay-based geological repository.
Understanding that process is crucial as countries worldwide consider underground clay formations for nuclear waste disposal.
18-Sep-2013 Supercomputing the transition from ordinary to extraordinary forms of matter
Supercomputing calculations plus experimental data from the Relativistic Heavy Ion Collider are helping scientists map out the nuclear phase diagram. This research offers insight into the transition of quark-gluon plasma to ordinary matter -- which mimics the formation of visible matter in the universe today.
27-Aug-2013 Third consecutive IEEE Cherry Award for NREL
Keith Emery always had amazing computer programming skills, but he lacked that special gift for creating solar cells. So, 30 years ago he switched to something more in his wheelhouse -- characterizing and measuring the efficiency of solar cells and modules.
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.
