Putting the squeeze on planets outside our solar system

Feb. 10, 2012 -  
LIVERMORE, Calif. -- Just as graphite can transform into diamond under high pressure, liquid magmas may similarly undergo major transformations at the pressures and temperatures that exist deep inside Earth-like planets. Using high-powered lasers, scientists at Lawrence Livermore National...

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...

In search of... the dark sky

Jan. 20, 2012 -  
Most astrophysicists stare at the night sky and look at stars. But Lance Simms looks at the blackness of night and knows there is something else there. Simms, a postdoc in the Lab's Physics Division, has been working for a year on a NASA project called the Cosmic X-Ray Background Nanosatellite (...

Grad student Swanberg recognized by APS

Jan. 18, 2012 -  
Erik Swanberg, a graduate student working in the Lab's Experimental Nuclear Physics Group, received the Margaret Burbidge Award from the American Physical Society (APS) California Section at the organization's fall 2011 meeting. Swanberg, who will earn a Ph.D. in nuclear engineering from UC...

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...

Planets around stars are the rule rather than the exception

Jan. 12, 2012 -  
LIVERMORE, Calif. --There are more exoplanets further away from their parent stars than originally thought, according to new astrophysics research. In a new paper appearing in the Jan. 12 edition of the journal, Nature , astrophysicist Kem Cook as part of an international collaboration, analyzed...

Lawrence Livermore Laboratory team achieves breakthrough detecting nuclear materials

Jan. 11, 2012 -  
When a young man was advised to pursue a career in plastics in the 1967 movie, "The Graduate," people could not have envisioned one of the material's uses developed by Lawrence Livermore National Laboratory (LLNL) scientists. In a key discovery, a team of LLNL researchers has developed the first...
