Making it count: Rebuilding infrastructure at the Nuclear Counting Facility

Oct. 8, 2021- 
When Daniel Martin put the finishing touches on an autonomous vehicle robot, complete with an ultrasonic sensor to detect and evade obstacles, he knew he wanted to become an engineer. A high school student at the time, he was fascinated by the design and functionality of robots. Fast forward several years, and Martin is now a second-year electrical engineering Ph.D. student at the University...

LLNL researchers observe laser-driven tin ejecta microjet interactions

Oct. 7, 2021- 
The experimental observations of high-velocity particle-laden flow interactions has been sparse, given the difficulty of generating high-velocity flows of many particles. These observations play an important role in understanding a wide range of natural phenomena, ranging from planetary formation to cloud interactions. That is, until now. In experiments conducted at the Omega Laser...

Just how big was the 2020 Beirut explosion?

Oct. 6, 2021- 
On Aug. 4, 2020, one of the largest non-nuclear explosions in history pulverized a Beirut port and damaged more than half the city. The explosion resulted from the detonation of tons of ammonium nitrate, a combustible chemical compound commonly used in agriculture as a high-nitrate fertilizer, but which can also be used to manufacture explosives. Since that time, the explosive yield...

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...

Lab garners five technology commercialization grants

Oct. 1, 2021- 
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...

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...

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.

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...
