Experiment sets new record in search for dark matter
Figuring out the nature of dark matter, the invisible substance that makes up most of the mass in our universe, is one of the greatest puzzles in physics. New results from the world’s most sensitive dark matter detector, LUX-ZEPLIN (LZ), have narrowed down possibilities for one of the leading dark matter candidates: weakly interacting massive particles, or WIMPs. LZ, led…

Bridging science and language: Writer Shelby Conn earns a master’s in English
For many, going back to school—whether to pursue an undergraduate, graduate, or certificate program—may feel like an impossible feat. However, Lawrence Livermore National Laboratory (LLNL) makes this achievement more attainable through the Employee Tuition Assistance Program (ETAP). It wasn’t until getting hired at LLNL in 2021 and finding out about the ETAP that Shelby…
Meet LLNL interns: Exploring work culture and environment
Each year, Lawrence Livermore National Laboratory (LLNL) welcomes hundreds of interns across its various directorates. These interns receive practical experience in their fields of interest within a stimulating environment. As early career professionals in training, they collaborate with their mentors and participate in projects that develop their skills in their…
Two LLNL researchers named to Optica’s 2024 class of senior members
Lawrence Livermore National Laboratory (LLNL) researchers Paul Armstrong and Brent Stuart have been named senior members of Optica. The professional society’s senior membership status recognizes members with more than 10 years of professional experience in optics or an optics-related field. The 2024 class joins a distinguished group of scientists, engineers, entrepreneurs…
Greenland ice sheet melted in recent past
Greenland was once actually green — even if it was close to a million years ago. But its lack of an ice sheet back then may lead to clues about the increased risk of sea-level rise in a warmer future. A new study provides the first direct evidence that the center, not just the edges, of Greenland’s ice sheet melted away in the recent geological past and the now-ice-covered…
Unveiling the key factors that determine properties of porous polymer materials
Determining the relationship between microstructure features and their properties is crucial for improving material performance and advancing the design of next-generation structural and functional materials. However, this task is inherently challenging. To address the challenges, LLNL scientists developed an efficient and comprehensive computational framework to decipher…
Chemical production gets a cleaner boost
A new electrochemical method can make chemical production cleaner and more energy-efficient. Using thin film nickel anodes, a team of Lawrence Livermore National Laboratory (LLNL) scientists and collaborators have figured out how to clean up chemical production. When studying a new electrochemical reaction, using thin films is important because they give a consistent…
It’s getting hot in here: lasers deliver powerful shocking punch
Shock experiments are widely used to understand the mechanical and electronic properties of matter under extreme conditions, like planetary impacts by meteorites. However, after the shock occurs, a clear description of the post-shock thermal state and its impacts on material properties is still lacking. Lawrence Livermore National Laboratory (LLNL) scientists used ultra…
Molecules get a boost from metallic carbon nanotubes
A Lawrence Livermore National Laboratory (LLNL) team has found that pure metallic carbon nanotubes are best at transporting molecules. Molecule separations play an ever-increasing role in modern technology from water desalination to harvesting critical materials to high-value chemicals and pharmaceuticals manufacturing. To enhance water and proton transport, LLNL…

Probing carbon capture, atom-by-atom
A team of scientists at Lawrence Livermore National Laboratory (LLNL) has developed a machine-learning model to gain an atomic-level understanding of CO2 capture in amine-based sorbents. This innovative approach promises to enhance the efficiency of direct air capture (DAC) technologies, which are crucial for reducing the excessive amounts of CO2 already present in the…
Confined water gets electric
When water gets inside nanopores with sizes below 10 nanometers, new physics emerge: new phases of ice were observed and ultrafast proton transport was measured. Confined water also plays a role in biology, where aquaporins cross cellular membranes to allow specific transport of water and other small molecules through nanometer-scale channels. However, this field lacks a…
Unveiling Bennu asteroid samples
Now at Lawrence Livermore National Laboratory (LLNL) lies a piece of ancient history. Very ancient history. The material, at just 120 milligrams, will provide information about the early solar system, planetary formation, and potentially, even ingredients for life on ancient Earth. LLNL scientists recently received and will analyze samples from the asteroid Bennu that will…
It’s all in the accounting
Natural ecosystems can be used to offset manmade CO2 and other greenhouse gas emissions that we add to the atmosphere, but the accounting needs to be right for carbon offset policies to be effective. For years, it’s been suspected that forest inventory and, more recently, biometeorological methods bias the carbon sequestration equation by potentially miscounting the…
