Science begins at the world’s most powerful X-ray laser
The first experiments are now underway using the world's most powerful X-ray laser, the Linac Coherent Light Source, located at DOE's SLAC National Accelerator Laboratory. Illuminating objects and processes at unprecedented speed and scale, the LCLS has embarked on groundbreaking research in physics, structural biology, energy science, chemistry and a host of other fields. -
'X-ray vision' on microbes that halt uranium deep underground
Like Superman, scientists can now "see" through layers of earth and rock. Unlike the Man of Steel, researchers are using this new ability to learn how microbes are halting uranium’s movement in groundwater underneath nuclear weapons sites. This new ability is known as surface spectral-induced polarization approach or SSIP. -
Turbine puts a new spin on wind energy
An innovative wind energy system designed to produce more power and last longer than traditional windmills is being tested at the Center for Advanced Energy Studies at DOE's Idaho National Laboratory. The system's most obvious distinction is the helicopter-like airfoils that rotate parallel to the ground, unlike most commercial turbines. -
Climate model first to factor nitrogen cycle
For the first time, climate scientists from across the country have successfully incorporated the nitrogen cycle into global simulations for climate change, questioning previous assumptions regarding carbon feedback and potentially helping to refine model forecasts about global warming. -
Innovative concepts at PPPL get ARRA lift
An additional $1.8 million in stimulus funding will benefit three innovative fusion energy research concepts at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL). The additional funding will be used for new instrumentation for critical measurements in fusion reactions, exploration of novel liquid lithium walls in a fusion machine, and an alternate approach for a fusion machine configuration—all research areas in the development of fusion as a potential energy source.
