(PhysOrg.com) -- Using high-powered lasers, scientists at Lawrence Livermore National Laboratory and collaborators discovered that molten magnesium silicate undergoes a phase change in the liquid state, abruptly transforming to a more dense liquid with increasing pressure. The research provides insight into planet formation.

(PhysOrg.com) -- Two teams of physicists at the U.S.

Thanks to a new online toolkit developed at MIT and the Lawrence Berkeley National Laboratory, any researcher who needs to find a material with specific properties — whether it’s to build a better mousetrap or a better battery — will now be able to do so far more easily than ever before.

Researchers from the Department of Energy's (DOE's) Lawrence Berkeley National Laboratory (Berkeley Lab) and the Massachusetts Institute of Technology (MIT) jointly launched today a groundbreaking new online tool called the Materials Project, which operates like a "Google" of material properties, enabling scientists and engineers from universities, national laboratories and private industry to accelerate the development of new materials, including critical materials.

California Governor Jerry Brown signed into law a ban for anyone under 18 years old from using ultraviolet tanning devices. Edward Lawrence reports.

The 2011 Nobel Prize in Physics goes to Saul Perlmutter at the Lawrence Berkeley National Lab, Brian Schmidt at the Australian National Lab and Adam Reiss at Johns Hopkins. The Royal Swedish Academy’s Olga Botner: “In a universe which is dominated by matter, one would expect gravity eventually should make the expansion slow down.

Scientists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and their colleagues have discovered a new relation among electric and magnetic fields and differences in temperature, which may lead to more efficient thermoelectric devices that convert heat into electricity or electricity into heat.

Every Friday afternoon for several years in the 1970s, a group of underemployed quantum physicists met at Lawrence Berkeley Laboratory, in Northern California, to talk about a subject so peculiar it was rarely discussed in mainstream science: entanglement. Did subatomic particles influence each other from a distance? What were the implications?

The creation of a new quasiparticle called the "hybrid plasmon polariton" may throw open the doors to integrated photonic circuits and optical computing for the 21st century. Researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory have demonstrated the first true nanoscale waveguides for next generation on-chip optical communication systems.

Your electric car might get you into heaven, but it's not going to save the Earth if China keeps up at its current pace. But while China may remain the world's largest energy consumer and CO2 emitter--that's just what happens when you represent 20% of humanity--the country can still put a dent in its energy and carbon consumption, stabilizing its emissions before mid-century

China's energy use should flatten out sometime around 2030, with a similar leveling off of its greenhouse gas emissions, a federal researcher said yesterday.

“Ooh, science!” said the mom, two little ones in tow. “We like science!” I was at the Lawrence Hall of Science station during the annual Easter Egg Roll at the White House yesterday, a tradition since 1878.

Programmable thermostats, which now make up about half the U.S. sales of all thermostats, could be more trouble for some than they're worth
