The definitive search for axion dark matter

Apr. 9, 2018 -  
Forty years ago, scientists theorized a new kind of low-mass particle that could solve one of the enduring mysteries of nature: what dark matter is made of. The search for that particle has just begun. This week, the Axion Dark Matter Experiment (ADMX) unveiled a new result (published in the April...

Night or day, Lab-developed space-based telescope can image Earth and beyond

Apr. 5, 2018 -  
Lawrence Livermore National Laboratory (LLNL) researchers have developed and tested an optical telescope system that can be used for Earth and space observation. The team, led by Wim de Vries, built and tested several designs for high-resolution monolithic optical telescope systems, fabricated from...

Martovetsky’s quest for carbon-free power endures at the world's largest fusion experiment

Mar. 30, 2018 -  
Growing up in Protvino, Russia, in the 1960s — home to the largest particle accelerator in the world when it launched in 1967­ — Lawrence Livermore National Laboratory (LLNL) scientist Nicolai Martovetsky quickly became fascinated with physics and math. “Protvino was one of the towns in Russia...

Machine learning models could save lives through personalized sepsis diagnostics

Apr. 4, 2018 -  
Researchers and clinicians may be able to track the progression of sepsis, a potentially life-threatening condition characterized by an extreme reaction to infection, with more precision and confidence using machine learning models developed at Lawrence Livermore National Laboratory ( LLNL ) in...

Lab scientists optimizing high performance fuels for advanced internal combustion engines

Mar. 20, 2018 -  
In support of the Department of Energy’s ( DOE ) Co-Optimization of Fuels & Engines (Co-Optima) initiative, Lawrence Livermore National Laboratory ( LLNL ) scientists are developing models of high performance fuels to see how they would perform in advanced internal combustion engines. The DOE...

Lab scientists to improve energy efficiency of copper catalysts that convert CO2 to methane

Mar. 8, 2018 -  
Lawrence Livermore National Laboratory (LLNL) researchers have received $1 million from the Department of Energy to improve the energy efficiency of copper-based catalysts to convert carbon dioxide into methane and other valuable hydrocarbon products. Led by LLNL’s Juergen Biener, the project will...

Lab employee and retiree named fellows

Mar. 2, 2018 -  
Two researchers affiliated with Lawrence Livermore National Laboratory (LLNL) -- a current employee and a retiree -- have been named fellows of the international Combustion Institute (CI). Bill Pitz, a combustion scientist in the Lab’s Materials Science Division, and Charlie Westbrook, a retired...

Earth’s core metals react well to electrons

Mar. 1, 2018 -  
At temperatures and pressures found on Earth’s surface, metallic elements are electropositive and lose their valence electrons to form positively charged cations. Metals have free electrons that naturally form compounds with electronegative elements. For example, iron reacts with oxygen to form...

Scientists find 'frustration' in battery materials

Feb. 22, 2018 -  
Adding carbon atoms to a new type of solid lithium ion battery could make it charge faster and more safely. Solid-state lithium-ion batteries can provide dramatically improved safety, voltage and energy density compared with today’s batteries, which use liquid components. They could be used in...

Drones deliver green transportation option

Feb. 13, 2018 -  
By getting your next package delivered by drone, you could be saving energy, but only if companies deploy drones sensibly. New research by Lawrence Livermore National Laboratory ( LLNL ), Carnegie Mellon University , SRI International and the University of Colorado at Boulder shows that drone-based...
