LLNL’s Rebecca Toomey recognized with Division of Nuclear Physics’ Distinguished Service Award
Rebecca Toomey, a postdoctoral research scientist at Lawrence Livermore National Laboratory (LLNL), has been recognized with the American Physical Society (APS) Division of Nuclear Physics’ (DNP) Distinguished Service Award. The honor is intended to recognize those who have made substantial and extensive contributions to the nuclear physics community through the activities…
LZ dark matter experiment sets a world’s best and spots neutrinos from the sun’s core
There’s more to the universe than meets the eye. Dark matter, the invisible substance that accounts for 85 percent of the mass in the universe, is hiding all around us — and figuring out exactly what it is remains one of the biggest questions about how our world works. The newest results from LUX-ZEPLIN (LZ) extend the experiment’s search for low-mass dark matter and set…
LLNL and Energy I-Corps take science from big ideas to big market impact
Lawrence Livermore National Laboratory (LLNL) pursues big ideas to solve the most important security challenges facing the U.S. and the world. In that pursuit, scientific breakthroughs with market potential are discovered, protected and licensed to (or collaborated on) with industry partners through a process called technology transfer. LLNL’s Innovation and Partnerships…
Undergraduate interns explore nuclear physics research at LLNL
Scientists at Lawrence Livermore National Laboratory (LLNL) recently helped launch a new internship program aimed at connecting with undergraduate students at two nearby California State University (CSU) campuses and inspiring them to consider a science-focused research career. The new program, which started in early 2025, involves multiple staff and postdocs from the Lab…
Energy-efficient process delivers rare-earth element for magnets
Neodymium is a rare-earth element essential for producing the strongest permanent magnets, which are widespread in defense technologies, hard drives, medical imaging devices, electric vehicle motors, wind turbines and more. Despite its designation in the U.S. as a critical material, neodymium is primarily mined and refined overseas. China controls much of the supply chain,…
Big Ideas Lab podcast traces the flow of energy in the U.S.
Inside a sixth-grade classroom, a teacher dims the lights and directs the student's attention to a projector. On the screen appears a brightly colored chart featuring thick, twisting bars extending from left to right. Some are as wide as rivers; others as narrow as threads. The diagrams look almost like a subway map for America’s energy. At the left, the lines “depart”…
Turning wastewater into valuable fertilizer
Almost half of the planet’s population depends on synthetic fertilizers to grow the food they eat. But that fertilizer comes at a cost — about two percent of the world’s energy budget. Improving efficiency and cutting costs of producing fertilizer would have big, global impacts. To that end, researchers at Lawrence Livermore National Laboratory (LLNL) are developing a…
LLNL conducts milestone nuclear survivability experiment at NIF, moving weapons modernization forward
Lawrence Livermore National Laboratory (LLNL) has conducted an experiment at the National Ignition Facility (NIF) to assess the ability of U.S. nuclear weapons to survive encounters with adversary missile defenses and reach their targets. This experiment demonstrated a new capability to analyze nuclear materials under extreme conditions, advancing stockpile modernization…
From inception to ignition and beyond: Suhas Bhandarkar’s target fabrication career
Tiny parts and absolute meticulousness define Suhas Bhandarkar’s award-winning 20-year career at Lawrence Livermore National Laboratory (LLNL). As group leader for Target Fabrication Science and Technology (S&T), he leads a team that helps transform LLNL’s physicists’ bold ideas into reality at the National Ignition Facility (NIF). Bhandarkar’s path began with a B.S…
STEM San Joaquin celebrates third year of inspiring young minds
STEM San Joaquin marked its third anniversary on Saturday, Nov. 15, at the University of the Pacific (UOP) in Stockton. Co-sponsored by Lawrence Livermore National Laboratory (LLNL) and UOP, the annual event welcomed students in grades 6–9 for a day of hands-on science, technology, engineering and math (STEM) exploration. The conference is organized by a dedicated team of…
Meteorite samples are time capsules from the early solar system
When a meteor streaks across the sky, it’s not just beautiful. It’s nature’s way of delivering a time capsule to Earth. Contained within are hints about the very beginning of the solar system and how planets, including our own, formed. Lawrence Livermore National Laboratory (LLNL) scientist Thomas Kruijer and collaborators describe how meteorites tell the story of the…
LLNL, UT & UCSD win Gordon Bell Prize with exascale tsunami forecasting
Researchers at Lawrence Livermore National Laboratory (LLNL), the University of Texas at Austin’s (UT) Oden Institute and Scripps Institution of Oceanography at the University of California San Diego (UCSD) on Nov. 20 were awarded the prestigious 2025 Association for Computing Machinery (ACM) Gordon Bell Prize for developing a real-time tsunami early-warning framework…
Not all immune cells are created equal
Memory T cells are a special type of white blood cell that “remember” past infections and vaccines, helping our bodies to quickly respond if we encounter the same germs again. These cells are found throughout the body: some circulate in the blood, while others settle down as “residents” in tissues like the lungs, intestines and lymphoid organs (such as the spleen and lymph…
Watching gold change structure at extreme pressures
The inside of giant planets can reach pressures more than one million times the Earth’s atmosphere. As a result of that intense pressure, materials can adopt unexpected structures and properties. Understanding matter in this regime requires experiments that push the limits of physics in the laboratory. In a recent paper published in Physical Review Letters, researchers at…
Researchers discover entirely new phase of ice
Water is weird. When ice cubes float at the top of a drink, they’re defying the norm. Solids are generally denser than liquids, so they sink. But because of its hydrogen bonds, water produces unusual and complex behaviors. Studying water ice and its various phases is crucial for understanding its strange properties. The knowledge is also critical for materials science,…
Experiments show how water could form on exoplanets, disrupting current theories
In the search for extraterrestrial life, the presence of water is a key signature of possible habitability. Identifying why some planets are wet and others are dry could help with the hunt. In a recent study published in Nature, scientists including Lawrence Livermore National Laboratory (LLNL) postdoctoral researcher Harrison Horn demonstrate a novel pathway for producing…
Mass spectrometry solves mysteries and unearths new questions in the Big Ideas Lab podcast
Scientists at Lawrence Livermore National Laboratory (LLNL) are solving cold cases and rewriting our knowledge of human history. Find out how the measurements made at the Laboratory’s Center for Accelerator Mass Spectrometry (CAMS) enable these feats on the latest episode of the Big Ideas Lab, available on Apple and Spotify. CAMS is one of the most advanced and prestigious…
Unique resin allows 3D-printing method to add and subtract
Additive manufacturing, or 3D printing, is normally a one-way street. In a digital light processing (DLP) printer, a structured pattern is projected onto a layer of liquid resin, which cures and solidifies. This builds an object up, layer-by-layer. But if the print isn’t exactly right, there’s no easy way to fix it after the fact: it usually ends up in the trash. In a new…
LLNL and partners launch record-breaking protein-folding workflow on world’s fastest supercomputer
