Researchers focus on how tantalum behaves at high pressure and temperature

Aug. 18, 2021- 
Lawrence Livermore National Laboratory (LLNL) researchers have explored high-pressure behavior of shock-compressed tantalum at the Omega Laser Facility at the University of Rochester’s Laboratory for Laser Energetics (LLE). The work showed tantalum did not follow the predicted phase changes at high pressure and instead maintained the body-centered cubic (BCC) phase until melt. The...

Simulating nuclear cloud rise anywhere, anytime

Aug. 16, 2021- 
For decades, understanding the behavior of a nuclear mushroom cloud was done with careful analysis of observations made during the testing era. Old photos, outdated film and incomplete weather data made precise calculations difficult. Now, with results published in Atmospheric Environment, Lawrence Livermore National Laboratory (LLNL) scientists are improving our understanding of nuclear...

IPCC reports climate change is widespread, rapid and intensifying

Aug. 9, 2021- 
Scientists are observing changes in the Earth’s climate in every region and across the whole climate system, according to the latest Intergovernmental Panel on Climate Change (IPCC) Report, released today. Many of the observed climate changes are unprecedented in thousands, if not hundreds of thousands of years, and some of the changes already set in motion — such as continued sea-level rise...
