LLNL researchers discover new way to ‘cage’ plutonium
Plutonium (Pu) exhibits one of the most diverse and complex chemistries of any element in the periodic table. Since its discovery in 1940, scientists have synthesized and studied many different types of plutonium-containing compounds using tools that reveal both their atomic structures and how they interact with light. Not only does plutonium have numerous alloys and…
Fentanyl or phony? Machine-learning algorithm learns to pick out opioid signatures
New forms of fentanyl are created every day. For law enforcement, that poses a challenge: how do you identify a chemical you’ve never seen before? Researchers at Lawrence Livermore National Laboratory (LLNL) aim to answer that question with a machine-learning model that can distinguish opioids from other chemicals with an accuracy over 95% in a laboratory setting. The…
When lasers cross: LLNL finds a brighter way to measure plasma
Measuring conditions in volatile clouds of superheated gases known as plasmas are central to pursuing greater scientific understanding of how stars, nuclear detonations and fusion energy work. For decades, scientists have relied on a technique called Thomson scattering, which uses a single laser beam to scatter from plasma waves as a way to measure critical information…
Lab physicist receives Sylvie Jacquemot Early Career Prize
Staff scientist Elizabeth Grace of Lawrence Livermore National Laboratory (LLNL) has been awarded the 2026 European Physical Society-Plasma Physics Division (EPS-PPCF) Sylvie Jacquemot Early Career Prize. “I am very honored to receive this award,” Grace said. “I appreciate the support from my mentors and the opportunities at LLNL, which made this work possible.” She was…
Simulations and supercomputing calculate one million orbits in cislunar space
Satellites and spacecraft in the vast region between the earth and moon and just beyond — called cislunar space — are crucial for space exploration, scientific advancement and national security. But figuring out where exactly to put them into a stable orbit can be a huge, computationally expensive challenge. In an open-access database and with publicly available code,…
Nanotubes with lids mimic real biology
When water and ions move together through channels only a nanometer wide, they behave in unusual ways. In these tight spaces, water molecules line up in single file. This forces ions to shed some of the water molecules that normally surround them, leading to the unique physics of ion transport. Biological channels are especially adept at this behavior, often choreographing…
Light-based 3D printing lets scientists program plastic properties at the microscale
Researchers at Lawrence Livermore National Laboratory (LLNL) have co-developed a new way to precisely control the internal structure of common plastics during 3D printing, allowing a single printed object to seamlessly shift from rigid to flexible using only light. In a paper published today in Science, the researchers describe a technique called crystallinity regulation…
LLNL’s energy scale-up brainstorming event focused on accelerating pilot-ready technologies
Solving tomorrow’s challenges in energy security requires scientists to develop new pathways to streamline innovation. To help achieve this goal, the Global Security Directorate at Lawrence Livermore National Laboratory (LLNL) recently hosted an “Energy Scale-up Brainstorming Day.” More than 60 researchers across a broad range of expertise gathered to engage in interactive…
LLNL releases Generalized Economics Model for fusion energy
Lawrence Livermore National Laboratory (LLNL) has released a new tool designed to help the fusion energy industry assess the economic impact of plant operation and design trade-offs for building an inertial fusion energy (IFE) power plant. The Generalized Economics Model (GEM) for Fusion Technology is now available to download. “GEM helps the fusion industry understand how…
Computing the future with Science on Saturday
Lawrence Livermore National Laboratory’s (LLNL) popular lecture series, “Science on Saturday,” will return on Feb. 7 and continue through Feb. 28 at Las Positas College in Livermore, Calif. The series features four engaging lectures under the theme “Computing the Future!” highlighting cutting-edge Laboratory research that uses the power of computing, from molecular biology…
Fusion Power Associates honor NIF target innovator Abbas Nikroo
Abbas Nikroo, deputy director for physics integration at Lawrence Livermore National Laboratory's (LLNL) National Ignition Facility (NIF), received the 2025 Distinguished Career Award by Fusion Power Associates (FPA). The FPA board of directors honored Nikroo for his “outstanding decades of unwavering commitment and leadership in scientific and management of the…
From fleeting to stable: scientists uncover recipe for new carbon dioxide-based energetic materials
When materials are compressed, their atoms are forced into unusual arrangements that do not normally exist under everyday conditions. These configurations are often fleeting: when the pressure is released, the atoms typically relax back to a stable low-pressure state. Only a few very specific materials, like diamond, retain their high-pressure structure after returning to…
Registration now open for LLNL summer education programs
Registration is now open for Lawrence Livermore National Laboratory’s (LLNL’s) summer science education programs. Summer 2026 offerings provide hands-on student experiences aligned with several LLNL research themes. Applications for summer 2026 are open now through Feb. 26. SAGE | June 8–12, onsite (Livermore Valley Open Campus) Science Accelerating Growth Engagement (SAGE…
New code connects microscopic insights to the macroscopic world
In inertial confinement fusion, a capsule of fuel begins at temperatures near zero and pressures close to vacuum. When lasers compress that fuel to trigger fusion, the material heats up to millions of degrees and reaches pressures similar to the core of the sun. That process happens within a miniscule amount of space and time. To understand this process, scientists need to…
Two LLNL scientists elected as 2026 Optica fellows
Optica recently elected 121 members from 23 countries to the society’s 2026 fellow class. Lawrence Livermore National Laboratory (LLNL) scientists Mark Henesian and Brent Stuart were among those honored by the scientific society. Optica fellows are selected based on outstanding contributions to research, business, education, engineering and service to Optica and the optics…
Next-generation materials for additive manufacturing
Next-generation technology requires next-generation materials that can be tailored to exact mission requirements. Additive manufacturing, or 3D printing, has already revolutionized industries like aerospace engineering by enabling previously unthinkable component designs. However, this technique has been largely limited to pre-existing metallic alloys. This is due to the…
When lightning strikes: Models of multi-ignition wildfires could predict catastrophic events
Multi-ignition wildfires are not overly common. But when individual fires do converge, the consequences can be catastrophic. The largest fire on record in California, the 2020 August Complex fire, grew from the coalescence of 10 separate ignitions. In a new study, published in Science Advances, researchers at Lawrence Livermore National Laboratory (LLNL), the University of…
LLNL, CFCE and Livermore Lab Foundation release AI primer for state lawmakers
Lawrence Livermore National Laboratory (LLNL), the California Foundation for Commerce and Education (CFCE) and the Livermore Lab Foundation (LLF) today released a new educational brief on the relationship between AI and California, designed to provide state lawmakers with science-based context as they consider AI policy decisions. The primer is intended to be a practical,…
What is dark matter? Explore the possibilities in the Big Ideas Lab podcast
Galaxies spin faster than they should. Clusters of those galaxies hold themselves intact against all expectations. By every visible measure, the universe should not look the way it does. Something is holding galaxies, stars and entire clusters together. Something we can’t see. And although it’s invisible to the naked eye, there are clues everywhere that allude to its…
