Model for COVID-19 drug discovery a Gordon Bell finalist
A machine learning model developed by a team of Lawrence Livermore National Laboratory (LLNL) scientists to aid in COVID-19 drug discovery efforts is a finalist for the Gordon Bell Special Prize for High Performance Computing-Based COVID-19 Research. Using Sierra, the world’s third fastest supercomputer, LLNL scientists created a more accurate and efficient generative…
Tiny tubes come in big packages
Membrane-based systems have great potential as low energy alternatives in applications like desalination, pharmaceutical recovery, purification and waste treatment. Scientists at Lawrence Livermore National Laboratory (LLNL) have created the largest defect-free membranes reported to date that fully exploit the unique mass transport properties of carbon nanotubes as flow…
LLNL wins two FLC awards for tech transfer
Two teams of Lawrence Livermore National Laboratory (LLNL) scientists and engineers, each supported by a Lab business development executive, have garnered regional awards for technology transfer. This year’s awards, one for outstanding technology development and the other for an outstanding partnership, will be presented next week during the Federal Laboratory Consortium’s…
Solar system formed in less than 200,000 years
A long time ago — roughly 4.5 billion years — our sun and solar system formed over the short time span of 200,000 years. That is the conclusion of a group of Lawrence Livermore National Laboratory (LLNL) scientists after looking at isotopes of the element molybdenum found on meteorites. The material that makes up the sun and the rest of the solar system came from the…
Lab will play key role in upcoming battery summit
Five Lawrence Livermore National Laboratory (LLNL) employees, including Director Bill Goldstein, will play key roles in the sixth annual Bay Area Battery Summit (BABS) slated to be held virtually next week. This year’s sixth annual BABS, co-sponsored by LLNL, New Energy Nexus and CalCharge, will draw together investors, policymakers, researchers and entrepreneurs with an…
LLNL welcomes 'Ruby' supercomputer for national nuclear security mission and COVID-19 research
Lawrence Livermore National Laboratory (LLNL), along with partners Intel, Supermicro and Cornelis Networks, have deployed “Ruby,” a high performance computing (HPC) cluster that will perform functions for the National Nuclear Security Administration (NNSA) and support the Laboratory’s COVID-19 research. Funded by NNSA’s Advanced Simulation and Computing (ASC) program, the…
Building a secure biosystem to protect microorganisms
To reduce the risk of unintended ecological consequences from environmentally deployed, genetically engineered microorganisms (GEMS), Lawrence Livermore National Laboratory (LLNL) scientists and collaborators are developing built-in “security mechanisms” that ensure they function where and when needed. The team hopes to stabilize GEMs to prevent the transfer of potentially…
LLNL, partners open access to CO2 storage simulator
After more than two years of joint research, Lawrence Livermore National Laboratory (LLNL), Total and Stanford University are releasing an open-source, high-performance simulator for large-scale geological carbon dioxide (CO2) storage. The GEOSX simulator will enable researchers around the world to build on the work of the three partners, providing an open framework to…
Lab explores new resins for light-based 3D printing
A Lawrence Livermore National Laboratory (LLNL) team has simulated the cross-linking of 3D-printed polymer networks, a key step toward developing new functional resins for light-based 3D-printing techniques including two-photon lithography (TPL) and volumetric additive manufacturing (VAM). The team used molecular dynamics simulations to study, at a microscopic level, the…
A PROMISE to trace the path of individual carbon atoms
Like water molecules in a river, soil carbon atoms are always in motion. To better understand this action, Lawrence Livermore National Laboratory (LLNL) scientists and collaborators have created a new conceptual framework as well as a simulation model that traces the path of individual carbon atoms as they interact with the environment -- undergoing biochemical…
DOE awards $18 million to LaserNetUS consortium
LaserNetUS, a network of facilities operating ultra-powerful lasers including those at Lawrence Livermore National Laboratory (LLNL), has received $18 million from the Department of Energy (DOE) for user support. Established in 2018 by DOE, LaserNetUS is organized and funded by DOE’s Office of Fusion Energy Sciences (FES). The new network was created to provide vastly…
New materials help expand volumetric 3D printing
Researchers at Lawrence Livermore National Laboratory (LLNL) have adapted a new class of materials for their groundbreaking volumetric 3D printing method that produces objects nearly instantly, greatly expanding the range of material properties achievable with the technique. The class of materials adapted for volumetric 3D printing are called thiol-ene resins, and they can…
Girls persevere for STEM in virtual conference
More than 150 girls logged into their computers, excited to participate in the first-ever virtual San Joaquin Expanding Your Horizons (SJEYH) conference via Zoom last month. Now in its 28th year, SJEYH has a long history of inspiring young women and fostering awareness of careers in science, technology, engineering and math (STEM). The annual event normally draws more than…
Mapping ‘fossil water’ helps achieve sustainable groundwater management in California
Identifying the areas where paleowater or “fossil water” — water that recharged before the Holocene started 12,000 years ago — is pumped for drinking water supply helps managers decide whether groundwater can sustainably meet future demands. This type of groundwater recharged during rainy periods under cooler and wetter conditions that ended about 10,000 years ago. Since…
