Rechargeable lithium batteries trace back to 1972, but they wouldn’t reach consumer products until 1991. Solar photovoltaic cells existed in the 1950s, long before solar panels appeared on rooftops. And the MRI was demonstrated in the 1970s, years before the machines became hospital staples. In each case, the core scientific principles had been proven. The difficult part…
A team of Lawrence Livermore National Laboratory (LLNL) scientists and engineers pushed the limits of unmanned aerial systems to earn a place at the DARPA Lift Challenge, hosted by the Defense Advanced Research Projects Agency (DARPA). The LLNL Collaborative Heavy-lift Aerial unManned Propellor Systems (CHAMPS) team ranked among the 132 teams selected from more than 480…
Small, modular nuclear fission reactors are emerging as a resilient energy option, offering a scalable, cost-effective path to reliable power for remote or infrastructure-limited locations. However, these advanced reactor facilities typically run hotter and longer than conventional light water reactors, so they will require a new type of nuclear fuel tough enough to…
While quantum computing could be the future, it is currently plagued by finicky hardware. To make the technology practical, researchers must demonstrate that it consistently and continuously works and performs at scale. In a new study, published in Physical Review Letters, researchers at Lawrence Livermore National Laboratory (LLNL) and the Ion Storage Group at the…
The FlowVAM system eliminates the need to manually exchange print volume in Tomographic Volumetric Additive Manufacturing and incorporates in situ metrology, yielding a 200-fold improvement in part production rates. Image credit: Hazel Rose Galvan/LLNL Lawrence Livermore National Laboratory (LLNL) scientists and engineers have earned six R&D 100 Awards, which recognize…
At the bottom of the ocean, optical fibers transmit telecommunications and internet data across the world. Waveguides make that feat possible by channeling and amplifying the light — and therefore the data within — over enormous distances. And the technology goes beyond undersea cables. Waveguiding optics are among the most important advances in photonics since the…
Each summer, students from across the country join Lawrence Livermore National Laboratory (LLNL) to gain hands-on experience, work alongside researchers and contribute to projects supporting the Lab’s mission. Meet four interns whose work spans emergency preparedness, artificial intelligence, actinide chemistry and additive manufacturing, and learn how their experiences…
Central to Lawrence Livermore National Laboratory’s (LLNL) prestigious Machinist Apprenticeship Program is a tradition of mentorship and support. That was evident on July 23, when four new apprentices joined the program and three graduating apprentices transitioned to state-certified machinists. “We are so proud of you,” said Manuel Iniguez, Manufacturing Engineering…
Lawrence Livermore National Laboratory (LLNL) scientists and engineers, in conjunction with the Department of Energy (DOE) and National Nuclear Security Administration (NNSA), are increasingly looking to AI, robotics and automation to help accelerate advanced manufacturing, materials discovery and experimental science. The work is part of a broader push to move faster from…
Lawrence Livermore National Laboratory called and the signal and image sciences community answered: The Center for Advanced Signal and Image Sciences (CASIS) hosted their 30th annual workshop at the University of California Livermore Collaboration Center (UCLCC) on June 24-25, setting new records for attendance and technical contributions in the workshop’s three-decade…
Many industrial processes produce large volumes of carbon as a waste product. New reactor technology from Lawrence Livermore National Laboratory (LLNL) has the potential to turn that waste into a valuable feedstock for useful chemicals and fuels. The result could bolster domestic manufacturing, diversify supply chains and ensure lasting energy security in the U.S. These …
Lawrence Livermore National Laboratory (LLNL) scientists and engineers have been selected to lead 10 Phase I projects under the U.S. Department of Energy’s (DOE’s) Genesis Mission, applying AI to challenges spanning high-performance computing (HPC), fusion energy, Earth systems science, materials discovery, biology, quantum technologies and fundamental physics. LLNL…
Lawrence Livermore National Laboratory (LLNL) has completed delivery of the first 220 line-replaceable units (LRUs) to the Integrated Test Stand (ITS) at Nevada National Security Sites (NNSS), as well as the first 100 LRUs to be used at NNSS’s underground facility, the Principal Underground Laboratory for Subcritical Experimentation (PULSE). The two major hardware delivery…
For grid-scale energy storage and national energy resilience, the U.S. needs better batteries. Lawrence Livermore National Laboratory (LLNL) scientists are tackling that challenge in many ways, but one approach is making a significant impact: physics-informed machine learning. In two recent publications, LLNL researchers examined how integrating molecular dynamics…
For decades, manufacturing plastic-bonded high explosives, or PBXs, has relied on legacy processes like slurry coating. In this method, explosive crystals are mixed with a binder, a polymer that helps hold the material together, to form small granules called prills. Those prills are then pressed into dense explosive parts. This process is difficult to control, inefficient…
When a high-intensity laser interacts with plasma, the charged particles typically oscillate back and forth like waves on the ocean. But what if the laser itself could twist like a whirlpool? Researchers have now demonstrated a rotating, spring-shaped laser pulse, opening up new possibilities for fusion energy, particle acceleration, astrophysics and beyond. In new…

The human brain is the ultimate supercomputer. It uses a highly-branched and interconnected network of neurons and synapses to achieve massive computational power with extreme efficiency. In the age of AI, the brain, a paradigm of efficient neuromorphic computing, is providing inspiration for scientists. Ionic computing — which uses ions to compute instead of the electrons…
Lawrence Livermore National Laboratory (LLNL) marked Site 300’s 70th anniversary in May with two events celebrating the Experimental Test Site’s history, mission and people: an Employee Appreciation Day and a family-focused open house. Although Site 300 reached its 70-year milestone last fall, celebrations were delayed due to a lapse in federal government funding. The…
