Scientists help define structure of exoplanets

Feb. 1, 2012 -  
LIVERMORE, Calif. -- Using models similar to those used in weapons research, scientists may soon know more about exoplanets, those objects beyond the realm of our solar system. In a new study, Lawrence Livermore National Laboratory scientists and collaborators came up with new methods for deriving...

Lab team develops new capability for atomistic simulations

Jan. 26, 2012 -  
Conventional scientific wisdom says that the interatomic forces between ions that control high-temperature processes such as melting are insensitive to the heating of the electron "glue" that binds the ions together. In effect, traditional atomistic simulations ignore electron temperature...

Scientists create new atomic X-ray laser

Jan. 26, 2012 -  
Lab scientists and international collaborators have created the shortest, purest X-ray laser pulses ever achieved, fulfilling a 45-year-old prediction and ultimately opening the door to new medicines, devices and materials. The researchers, reporting today (Jan. 26) in Nature , aimed radiation from...

Seeing is believing: LLNL Postdoc reveals wonders of the protist world

Jan. 17, 2012 -  
No matter how sophisticated instruments have become, or how data intensive results may be, there is still something satisfying and frequently informative about seeing what a researcher is studying. Sometimes samples are so small, or so large, or so far away that it's almost impossible to get a...

Power generation is blowing in the wind

Jan. 17, 2012 -  
LIVERMORE, Calif. -- By looking at the stability of the atmosphere, wind farm operators could gain greater insight into the amount of power generated at any given time. Power generated by a wind turbine largely depends on the wind speed. In a wind farm in which the turbines experience the same wind...

Lawrence Livermore receives $1.75 million to integrate more renewable sources into California's energy grid

Dec. 19, 2011 -  
Lawrence Livermore National Laboratory (LLNL) is working with the California Energy Commission to develop ways to increase the amounts of wind and solar generation integrated into California's energy grid. The project will use LLNL's high-resolution weather models and high performance computing to...
