Measuring electrical properties of methane hydrates leads to better understanding of gases in seafloors

Sept. 28, 2020- 
Methane hydrate is a crystalline solid formed from methane gas and water that occurs naturally in the seafloor of the continental shelves worldwide. Hydrate is considered a source of natural gas, a natural hazard or a potential contributor to ocean acidification and climate change. Its presence lowers the electrical conductivity of the seafloor in comparison to hydrate free formations...

Going with the flow for water purification

Sept. 18, 2020- 
Membrane separations have become critical to human existence, with no better example than water purification. As water scarcity becomes more common and communities start running out of cheap available water, they need to supplement their supplies with desalinated water from seawater and brackish water sources. Lawrence Livermore National Laboratory (LLNL) researchers have created...

Sept. 17, 2020- 
Jasmine Bowers, former summer student at Lawrence Livermore National Laboratory (LLNL), recently made history when she became the first African American to earn a doctorate in computer science from the University of Florida, where she attended through the GEM fellowship program. Not a surprising feat considering Bowers’ long list of accomplishments, starting in 2008 when she was...

Antibiotic pre-treatment reduces joint inflammation

Sept. 16, 2020- 
Tearing an anterior cruciate ligament (ACL) can be an excruciatingly painful injury. Nearly 50 percent of these patients will develop a secondary form of osteoarthritis, deemed post-traumatic osteoarthritis (PTOA). Researchers from Lawrence Livermore National Laboratory (LLNL) and the UC Davis Medical Center have found that treatment with antibiotics prior to the injury could reduce...

A simple explanation to paradox of a spiraling football

Sept. 9, 2020- 
The hallmark of a perfectly thrown football is a tight spiraling of the tip around the trajectory of the parabolic path of flight. Why the tip follows the trajectory has presented a paradox for some time. A team of researchers, including Lawrence Livermore National Laboratory (LLNL) physicist Willy Moss, provided a simple resolution to this paradox in a paper published as an Editor’s...

Inspiring future physicist while exploring dark energy

Sept. 8, 2020- 
Doctoral student Victor Baules is spending his summer exploring the connection between dark energy and the expansion of our universe, but due to the pandemic, his research fellowship is more down-to-earth, taking place from his home in Alabama. Baules’ research trajectory in high-energy theory aligns with astrophysics research at Lawrence Livermore National Laboratory (LLNL), where...

ICF implosions have significant 3D asymmetries

Sept. 4, 2020- 
Data correlating two factors that lead to implosion asymmetries have brought Lawrence Livermore National Laboratory (LLNL) scientists a step closer to understanding the gap between simulations and performance of inertial confinement fusion (ICF) experiments at the National Ignition Facility (NIF). These experiments aim to ignite a propagating fusion burn wave in deuterium-tritium fuel. To...

Looking skin deep at the growth of neutron stars

Sept. 3, 2020- 
In atomic nuclei, protons and neutrons share energy and momentum in tight quarters. But exactly how they share the energy that keeps them bound within the nucleus — and even where they are within the nucleus — remain key puzzles for nuclear physicists. A new study by researchers at Lawrence Livermore National Laboratory (LLNL) and Washington University in St. Louis tackled these...

LLNL volunteers aid first responders during wildfire

Sept. 2, 2020- 
When a severe lightning storm sparked what would become a conflagration consuming more than 390,000 acres and threatening the communities of Livermore and Pleasanton, volunteers with Lawrence Livermore National Laboratory’s Community Emergency Response Team (CERT) answered the state’s call for help. Ignited by unusual summer thunderstorms in the early morning hours of Aug. 16, the blaze...
