LLNL researchers identify simple way to mitigate traumatic brain injury
U.S. troops from traumatic brain injury (TBI).
Using computational models and computing resources originally developed for
its nuclear weapons/stockpile stewardship mission, researchers at DOE's
Lawrence Livermore National Laboratory have identified a way to help protect

A shared approach for climate insight
Around the world, scientists are modeling the impact of aerosols, tiny atmospheric particles that could play a big role in global climate change. Each model is different, drawing on different data sets and different configurations. When plugged into global climate models, it is not clear which smaller model is more accurate or computationally less expensive. So, scientists at DOE’s Pacific Northwest National Laboratory developed the Aerosol Modeling Testbed, which allows scientists to evaluate their models in a collaborative environment.

Sharpening the plasmon nanofocus
Plasmonics is one of the hottest fields in technology today. Electronic surface waves called plasmons can be generated by confining electromagnetic waves shorter than half the wavelength of incident light, for example at the interface between gold nanostructures and insulating air.

High-energy density magnesium batteries for smart electrical grids
Magnesium-based batteries are, in theory, a very attractive alternative to other batteries. Magnesium (Mg) is cheap, safe, lightweight, and its compounds are usually non-toxic. Mg is less expensive (metallic lithium [Li] costs about 24 times more than metallic Mg) because Mg is abundant in the Earth’s crust.

Criticality experiment succeeds at CEF in Nevada
On June 15 a team of researchers at DOE’s Los Alamos National Laboratory brought the Planet criticality assembly machine located at the Nevada National Security Site to a supercritical point for approximately eight minutes, successfully repeating an experiment last conducted at Los Alamos in 2004.
