Preventing close encounters of the orbiting kind

Apr. 26, 2011 -  
Each day, hundreds of active satellites as well as tens of thousands of pieces of "space junk" -- defunct satellites, bits of booster rockets and lost astronaut tools -- orbit Earth. This space junk became front page news two years ago, when a defunct Russian satellite and a privately owned...

Hydrocarbons in the deep earth

Apr. 14, 2011 -  
LIVERMORE, Calif. -- A new computational study published in the Proceedings of the National Academy of Sciences reveals how hydrocarbons may be formed from methane in deep Earth at extreme pressures and temperatures. The thermodynamic and kinetic properties of hydrocarbons at high pressures and...

Livermore researchers develop battery-less chemical detector

Apr. 6, 2011 -  
Unlike many conventional chemical detectors that require an external power source, Lawrence Livermore researchers have developed a nanosensor that relies on semiconductor nanowires, rather than traditional batteries. The device overcomes the power requirement of traditional sensors and is simple,...

Oldest objects in solar system indicate a turbulent beginning

Mar. 3, 2011 -  
LIVERMORE, Calif. -- Scientists have found that calcium, aluminum-rich inclusions (CAIs), some of the oldest objects in the solar system, formed far away from our sun and then later fell back into the mid-plane of the solar system. The findings may lead to a greater understanding of how our solar...
