New research delves into fate of ocean carbon

Sept. 28, 2021- 
Marine-dissolved organic matter, which originates from phytoplankton, holds as much carbon as Earth’s atmosphere, yet the biological processes governing its fate are primarily studied under idealized laboratory conditions or through indirect measures such as genome sequencing. In new research by a Lawrence Livermore National Laboratory (LLNL) scientist and collaborators at Oregon State...

A new Virtual Discovery Center experience

Sept. 28, 2021-

With the center closed to the public during to the pandemic, the Lab has pivoted the Discovery Center experience from in-person to virtual. “LLNL is pleased to introduce the all-new Virtual Discovery Center,” said Joanna Albala, LLNL’s Science...

Shock waves in outflow gases could regulate ‘volcano lightning’

Sept. 27, 2021- 
Volcanic eruptions spew lava, rock and ash into the air. When fragments of these materials mix and collide in the outflow, they can create an electric potential large enough to generate lightning. New research by Lawrence Livermore National Laboratory (LLNL) scientists and collaborators discovered that standing shock waves in the supersonic outflow of gases prevent electric discharges like...

Lawrence Livermore researchers focus on fast flows in thermonuclear fusion

Sept. 24, 2021- 
Imagine having a balloon between both hands and trying to squeeze it with the same force on all sides so that it uniformly shrinks down. However, if you push on one side harder than the other the balloon won’t compress uniformly and will, in fact, move away from the hand that is pushing harder. The same thing happens when the drive pushing on an inertial confinement fusion (ICF) capsule...

Come on in, the water is superionic

Sept. 23, 2021- 
The interiors of Uranus and Neptune each contain about 50,000 times the amount of water in Earth’s oceans, and a form of water known as superionic water is believed to be stable at depths greater than approximately one-third of the radius of these ice giants. Superionic water is a phase of H2O where hydrogen atoms become liquid-like while oxygen atoms remain solid-like on a crystalline...

LLNL explores laser beam shaping to improve metal 3D printing

Sept. 22, 2021- 
While laser-based 3D printing techniques have revolutionized the production of metal parts by greatly expanding design complexity, the laser beams traditionally used in metal printing have drawbacks that can lead to defects and poor mechanical performance. Researchers at Lawrence Livermore National Laboratory (LLNL) are addressing the issue by exploring alternative shapes to the Gaussian...

Industry sponsors included...

Nuclear waste interaction in the environment may be more complicated than once thought

Sept. 21, 2021- 
Lawrence Livermore National Laboratory (LLNL) scientists and collaborators have proposed a new mechanism by which nuclear waste could spread in the environment. The new findings, which involve researchers at Penn State and Harvard Medical School, have implications for nuclear waste management and environmental chemistry. The research is published in the Journal of the American...

Lawrence Livermore’s pressing operations with high explosives reach new milestones

The webinar’s plenary session comprises talks...

What if just one airborne particle was enough to infect you?

Sept. 16, 2021- 
For some diseases, exposure to just a single airborne particle containing virus, bacteria or fungi can be infectious. When this happens, understanding and predicting airborne disease spread can be a whole lot easier. That’s the result of a new study by a Lawrence Livermore National Laboratory (LLNL) scientist who developed a new theory of airborne infectious disease spread. This research...
