Putting the squeeze on planets outside our solar system

February 12, 2012 4:59 pm | by Anne M. Stark | News | Comments

In recent research using high-powered lasers, a Lawrence Livermore National Laboratory-led team has discovered that 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. The findings provide a potential blueprint for planet formation.

Scientists help define structure of exoplanets

February 1, 2012 4:26 am | News | Comments

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 and testing the equation of state of matter in exoplanets and figured out the mass-radius and mass-pressure relations for materials relevant to planetary interiors.

Lab team develops new capability for atomistic simulations

January 27, 2012 3:31 am | News | Comments

Conventional scientific wisdom says that the interatomic forces between ions that control high-temperature processes are insensitive to the heating of the electron "glue" that binds the ions together. In effect, traditional atomistic simulations ignore electron temperature completely. However, physicists at the Lawrence Livermore National Laboratory have shown how electron temperature has a surprisingly large impact on phase stability and melting in refractory transition metals.

In search of the dark sky

January 23, 2012 5:21 am | News | Comments

Most astrophysicists stare at the night sky and look at stars. But Lance Simms from Lawrence Livermore National Laboratory looks at the blackness of night and knows there something else there. Simms has been working for a year on a NASA project called the Cosmic X-Ray Background Nanosatellite. The breadbox-sized satellite, set for an August launch, will gather X-ray data from the cosmos and beam it back to Earth.

Power generation is blowing in the wind

January 17, 2012 4:59 am | News | Comments

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 speeds but different shapes, such as turbulence, to the wind profile, a turbine will produce different amounts of power.


Team achieves breakthrough detecting nuclear materials

January 11, 2012 7:51 am | News | Comments

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 plastic material capable of efficiently distinguishing neutrons from gamma rays, something not thought possible for the past five decades or so.

Separating signal and noise in climate warming

November 17, 2011 9:21 am | News | Comments

In order to separate human-caused global warming from the "noise" of purely natural climate fluctuations, temperature records must be at least 17 years long, according to climate scientists. To address criticism of the reliability of thermometer records of surface warming, Lawrence Livermore National Laboratory scientists analyzed satellite measurements of the temperature of the lower troposphere and saw a clear signal of human-induced warming of the planet.

Americans using more fossil fuels

November 9, 2011 8:49 am | News | Comments

American energy use went back up in 2010 compared to 2009, when consumption was at a 12-year low. The United States used more fossil fuels in 2010 than in 2009, while renewable electricity remained approximately constant, with an increase in wind power offset by a modest decline in hydroelectricity. There also was a significant increase in biomass consumption, according to the most recent energy flow charts released by the Lawrence Livermore National Laboratory.
