Latest Lawrence Livermore National Laboratory Stories
Lawrence Livermore National Laboratory researchers have for the first time simulated and quantified the early stages of radiation damage that will occur in a given material.
U.S. researchers are perfecting simulations that show a nuclear weapon's performance in precise molecular detail, tools that are becoming critical for national defense because international treaties forbid the detonation of nuclear test weapons.
Scientists report that in the last fifty years, salinity levels in the world’s oceans have shifted and that climate change is affecting global rainfall and evaporation cycles.
For the first time, scientists have seen an X-ray-irradiated mineral go to two different states of matter in about 40 femtoseconds (a femtosecond is one quadrillionth of a second).
A new report published by an American non-profit research center says that extreme summer temperatures are becoming increasingly commonplace in the United States, a trend that they project will continue throughout the 21st century.
Phase transitions in liquid magmas at the pressure and temperature levels that exist deep within Earth-like planets could play a role in the formation of new worlds.
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.
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.
Massive Compact Halo Object (MACHO) -- Massive compact halo objects, or MACHOs, are a type of astronomical body proposed as one possible explanation for the presence of dark matter in galactic halos. A MACHO is a small chunk of normal baryonic matter, far smaller than a star, which drifts through interstellar space unassociated with any solar system. Since MACHOs would not emit any light of their own, they would be very hard to detect. Recent work has suggested that MACHOs are not...
