Looking into the void to cancel out material instabilities
Picture two materials sandwiched together. The boundary between them may appear flat, but, in reality, it is full of tiny bumps and dents. Suddenly, the materials are hit with a shockwave. If that wave hits a bump in the material interface, it slows down. If it hits a dent, it accelerates forward. This imbalance creates fast, narrow jets of material — called the Richtmyer…

NNSA and LLNL advance laser upgrade for nuclear stockpile mission ahead of schedule
The U.S. Department of Energy (DOE) and National Nuclear Security Administration (NNSA) have approved a path forward for a project that will increase the laser energy available to the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory (LLNL). This advancement was expedited by key regulatory changes made in March 2025 by U.S. Secretary of Energy…
Cryogenic micro-calorimetry offers a novel material-dating method for nuclear forensics and safeguards
The moment nuclear material is produced, processed or purified, it sets off a hidden countdown, marked by the half-life of its radioactive atoms as they begin to decay. For scientists tracking the origins of these substances, decoding this natural clock is crucial for verifying material histories in support of global security efforts. In a new study published in the…
NNSA Administrator Williams visits LLNL to discuss stockpile modernization, AI and future deterrence
U.S. Department of Energy (DOE) Under Secretary for Nuclear Security and Administrator of the National Nuclear Security Administration (NNSA) Brandon Williams visited Lawrence Livermore National Laboratory (LLNL) Feb. 9 for briefings and tours focused on stockpile modernization, AI, supercomputing and the future of deterrence. During the visit, Williams met with LLNL…
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,…
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…
Discover LLNL’s Autonomous Sensors program in the latest episode of the Big Ideas Lab podcast
When disaster strikes, every second counts, but sometimes the danger is too great for humans to go first. From mapping terrain to reaching deep underground to detect hidden threats and abandoned wells, unmanned systems equipped with advanced sensors are changing how we respond to crises. Across land, air and sea, drones can act as one coordinated force to increase the…
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…
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…
