Powering up: LLNL prepares for exascale with massive energy and water upgrade

Oct. 18, 2021- 
A supercomputer doesn’t just magically appear, especially one as large and as fast as Lawrence Livermore National Laboratory’s upcoming exascale-class behemoth El Capitan. At peak usage, El Capitan — projected to be the world’s most powerful computer by 2023 — will require about as much energy as a small city, so it takes years of planning, infrastructure upgrades and an entirely new way of...

Updated exascale system for earth simulations

Oct. 14, 2021- 
A new version of the Energy Exascale Earth System Model (E3SM) is two times faster than its earlier version released in 2018. Earth system models have weather-scale resolution and use advanced computers to simulate aspects of Earth’s variability and anticipate decadal changes that will critically impact the U.S. energy sector in coming years. Version 2 of the Energy Exascale Earth...

The four graduate students are among 65 individuals representing 29 states who will conduct research at various DOE national laboratories. The students hosted by...

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...

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...

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...

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...

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...
