Climate change in the Sierra Nevada has profoundly altered its lake ecosystems

Oct. 5, 2021- 
Climate change has significantly impacted the natural systems of the Sierra Nevada, including the mountain lakes that are an iconic part of California’s natural beauty. New research from a Lawrence Livermore National Laboratory (LLNL) scientist and colleagues from the University of Kentucky (UK) and Indiana State University (ISU) shows that lake-sediment cores from a subalpine lake in...

Late-time small-body disruptions can protect the Earth

Oct. 5, 2021- 
If an asteroid is determined to be on an Earth-impacting trajectory, scientists typically want to stage a deflection, where the asteroid is gently nudged by a relatively small change in velocity, while keeping the bulk of the asteroid together. A kinetic impactor or a standoff nuclear explosion can achieve a deflection. However, if the warning time is too short to stage a successful...

Lawrence Livermore National Laboratory (LLNL) scientists and engineers have posted another banner year securing major grants through the Department of Energy’s (DOE) Technology Commercialization Fund (TCF). “I think the Laboratory did very well again, reflecting a variety of types and approaches to our research and development projects,” said Rich Rankin, the director of the Lab’s...

LLNL team wins $15 million to study how microbes affect carbon storage

Oct. 1, 2021- 
Do dead microbes control the future of Earth’s climate? A team of researchers led by Lawrence Livermore National Laboratory (LLNL) suspects they might. Using new tools, the team can see which soil organisms are thriving and which are dying in California’s changing climate — and what happens to carbon in their cell biomass when they do. The seven-institution team has just been awarded...

At the extreme: Breaking the ice mold

Sept. 30, 2021- 
New research involving Lawrence Livermore National Laboratory (LLNL) scientists shows that water can remain liquid in a metastable state when transitioning from liquid to a dense form of ice at higher pressures than previously measured. Water at extreme conditions has attracted recent attention because of its complex phase diagram, including superionic ice phases having exotic...

A bigger nursery for the solar system’s first formed solids

Sept. 29, 2021- 
The earliest solids formed in the solar system give clues to what radioactive species were made by the young sun, and which ones were inherited. By studying isotopic variations of the elements vanadium (V) and strontium (Sr), an international team of researchers including scientists from Lawrence Livermore National Laboratory (LLNL) found that those variations are not caused by...

R-cubed: Revolutionizing the present, anticipating the future

Sept. 29, 2021- 
The Post-Detonation Rapid Response Research Venture — also known as R-cubed or R3 — is combining basic research and development of emergent technologies, predictive capabilities and systems assessment to revolutionize the speed and flexibility of technical nuclear forensic (TNF) response to nuclear events.  The venture is a multi-laboratory collaboration led by Lawrence Livermore...

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- 
For decades, Lawrence Livermore National Laboratory’s (LLNL’s) Discovery Center has served as a window into LLNL’s state-of-the-art research. 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...

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...
