'Egg-cellent' world-record battery performance
SLAC and Stanford scientists have set a world record for energy storage, using a clever "yolk-shell" design to store five times more energy in the sulfur cathode of a rechargeable lithium-ion battery than is possible with today's commercial technology.

Sandia airborne pods seek to trace nuclear bomb's origins
If a nuclear device were to unexpectedly detonate anywhere on Earth, the ensuing effort to find out who made the weapon probably would be led by aircraft rapidly collecting airborne radioactive particles for analysis.

How cool are cool roofs? PPPL serves as the laboratory to find the answer
When Keith Rule and a team of interns walked onto the black and white roof of the main building of the US Department of Energy's Princeton Plasma Physics Laboratory one sweltering day last summer, they could feel the temperature difference between the two different colored areas in the soles of their feet.

Growth Forum offers networking nirvana
A greener detergent, a better solar-cell coating, an off-the-grid freezer -- clean-tech entrepreneurs pitched their ideas to money-men and -women in 10-minute bursts at the 2012 Industry Growth Forum last month in Denver. The US Department of Energy's National Renewable Energy Laboratory held the 25th Industry Growth Forum, an annual event that features presentations from emerging clean energy companies, provocative panels led by thought leaders, one-on-one meetings, and organized networking opportunities.

Special report: Graphics processing units speed results in extreme-scale supercomputers
Can scientists and engineers benefit from extreme-scale supercomputers that use application-code accelerators called GPUs (graphics processing units)? Comparing GPU accelerators with today's fastest central processing units (CPUs), early results from diverse areas of research show 1.5- to 3-fold speedups for most codes. That acceleration means increased realism of simulations and decreased time to results. A special report details these findings.

Idaho researcher building used nuclear fuel sensor
Much of the 6,200 metric tons of used nuclear fuel generated by US power plants over the last 40 years is stored safely in giant stainless steel casks. Darryl Butt, a Boise State University professor, is part of a team researching whether it can be stored that way for at least 60 more.

Snubbed protons tattle on neutron structure
Protons and neutrons are the fraternal twins of the sub-atomic world and the building blocks of all atomic nuclei. While similar in many respects, it's their differences that give them their unique properties. Now, scientists are exploiting these differences to gain deeper insight into these fundamental particles that build our visible universe.

Supernovas explode in 3-D detail at Oak Ridge National Laboratory
Understanding a Type Ia supernova -- an exploding white dwarf star -- requires supercomputers. A team of astrophysicists and computational scientists is using the power of Oak Ridge National Laboratory's Jaguar to virtually blow up these white dwarfs. In the process the researchers are revealing the secrets of the biggest thermonuclear explosions in the universe and finding the answers needed to measure the size of the universe.

NREL catalyst brings drop-in fuels closer
We live in a petroleum-based society, and the oil we use comes from plants that were buried eons ago and changed under pressure and high temperatures. As countries across the globe face dwindling oil supplies and the environmental impacts of tapping hard-to-process shale oil, the question arises: is there a greener way to replicate Mother Nature?

New nanoparticle technology cuts water use, energy costs
Nuclear and coal power plants are some of the thirstiest machines on earth. The turbines that spin inside of them to generate electricity require tons and tons of steam, and all of that water has to come from somewhere.

Carbon dioxide caused global warming at ice age's end, pioneering simulation shows
Climate science has an equivalent to the "what came first -- the chicken or the egg?" question: what came first, greenhouse gases or global warming? A multi-institutional team led by researchers at Harvard, Oregon State University, and the University of Wisconsin used a global dataset of paleoclimate records and the Jaguar supercomputer at Oak Ridge National Laboratory to find the answer. The results, published in the April 5 issue of Nature, analyze 15,000 years of climate history.

Climate scientists compute in concert
Researchers at Oak Ridge National Laboratory are sharing computational resources and expertise to improve the detail and performance of a scientific application code that is the product of one of the world's largest collaborations of climate researchers. The Community Earth System Model couples components of atmosphere, land, ocean, and ice to reflect their complex interactions. By continuing to improve science representations and numerical methods in simulations, and exploiting modern computer architectures, researchers expect to further improve the CESM's accuracy in predicting climate changes.

Computation proves predictive capabilities of nuclei through fluorine-14 simulation
Aa team led by Iowa State University physicist James Vary used Oak Ridge Leadership Computing Facility and Argonne Leadership Computing Facility resources to predict the behavior of fluorine-14, a relatively unknown isotope. It published its predictions in Physical Review C in February 2010. Six months later, a group of researchers at Texas A&M University's Cyclotron Institute performed an experiment producing fluorine-14, and the results nearly mirrored those of Vary's group.
