Soil carbon storage rocks on

Nov. 15, 2021- 
Rock weathering controls the potential for soil carbon storage at a continental scale. New research from Lawrence Livermore National Laboratory (LLNL) and collaborators found that rock weathering the process of chemical transformation by long exposure to water and the atmosphere boosts soil organic carbon storage by altering soil mineralogy. The research appears in the journal Biog...

Livermore Lab Foundation, Lawrence Livermore National Lab launch carbon education and outreach program

Nov. 12, 2021- 
Helping the general public and students learn about carbon neutrality, the options for carbon dioxide removal, as well as the effects of climate change, is the focus of the Carbon Cleanup Initiative, a unique public awareness partnership from the Livermore Lab Foundation (LLF) and Lawrence Livermore National Laboratory (LLNL). “We are proud to partner with the scientists and engineers...

U.S. Department of Energy to showcase national lab expertise at SC21

Nov. 11, 2021- 
The scientific computing and networking leadership of the U.S. Department of Energy’s (DOE’s) national laboratories will be on display at SC21, the International Conference for High-Performance Computing, Networking, Storage and Analysis. The conference takes place Nov. 14-19 in St. Louis via a combination of on-site and online resources. The theme of this year’s conference is...

LLNL-led team uses machine learning to derive black hole motion from gravitational waves

Nov. 9, 2021- 
The announcement that the Laser Interferometer Gravitational-wave Observatory (LIGO) had detected gravitational waves during the merger of two black holes sent ripples throughout the scientific community in 2016. The earthshaking news not only confirmed one of Albert Einstein’s key predictions in his general theory of relativity, but also opened a door to a better understanding of the motion...

Human-caused climate change increases wildfire activity

Nov. 8, 2021- 
The western United States has experienced a rapid increase of fire weather as the vapor pressure deficit (VPD) increases in the area during the warm season. New research by scientists at University of California, Los Angeles (UCLA) and Lawrence Livermore National Laboratory (LLNL) shows that two-thirds (approximately 68 percent) of the increase in VPD is due to human-caused climate change...

Disorder in surface materials key to better hydrogen storage

Nov. 4, 2021- 
Lawrence Livermore National Laboratory (LLNL) scientists have found that atomic disorder in certain boron-based hydrogen storage systems can potentially improve the rate of hydrogen uptake. Metal boride surfaces and their single-layer variants — known as borophenes — are generally thought to feature a regular arrangement of atoms at low to moderate temperatures. The LLNL team proved...

Survivor salmon persist through drought and ocean warming

Nov. 2, 2021- 
In drought years and when marine heat waves warm the Pacific Ocean, the rare late-migrating juvenile spring-run Chinook salmon of California’s Central Valley are the survivors. They are among the few salmon that return to spawning rivers in those difficult years to keep their populations alive, according to results published today in Nature Climate Change. The trouble is that these...
