LLNL’s Forensic Science Center develops a new capability to detect chemical weapons
In the aftermath of suspected chemical attacks, investigators from the Organization for the Prohibition of Chemical Weapons (OPCW) step in to collect chemical, environmental and biomedical samples. Thorough forensic laboratory analysis of these samples is essential for proving what — if any — chemical agents were used and verifying their identities. Researchers at Lawrence…
Meet Alex Baker: Deputy Group Leader, Advanced Materials Process Science
Alex Baker wears many hats at LLNL; his roles run the gamut from project leadership to operations efforts to scientific research of his own. Being from the United Kingdom, he traveled quite a distance to get here, but it was no accident. Baker completed his PhD at Oxford University and Diamond Light Source, one of the UK’s national labs, during which he regularly visited…
Tuning plasma edge density suppresses damaging tokamak instabilities
Tokamak fusion reactors use powerful magnetic fields to confine superheated plasmas, but the plasma edge—the outermost region where magnetic containment begins to weaken—can become unstable. These instabilities, called edge-localized modes (ELMs), can suddenly release intense bursts of heat and particles toward reactor walls and the divertor, the exhaust system that…
Analyze an asteroid sample in the latest episode of the Big Ideas Lab
In the early 2000s, a team of planetary scientists at NASA began planning something audacious. They would build a spacecraft. Aim it at an asteroid. Launch it across more than a billion miles of space. Map the asteroid’s rugged terrain at an unprecedented, centimeter-level resolution. Hover over the surface to collect a sample. And then bring it all the way home. The…
Meet the machines that matter: the Electron Beam Ion Trap
Imagine listening to an orchestra: overlapping notes, blended timbres and complex harmonies coming together into a cohesive symphony. Now try to isolate a single instrument and the sounds it produces. Nearly impossible, right? The same is true for collections of ions, charged particles that have gained or lost electrons. Each ion — from hydrogen to lithium to lead and…
Roll the tape: LLNL captures inception of hydrogen-uranium reaction for the first time
When hydrogen gas interacts with uranium metal, the combination creates a chemically reactive powder and a runaway reaction that is difficult to stop. The result can impact the safety and lifespan of technology critical for fusion energy, hydrogen storage and nuclear fuels. In a recent study published in npj Materials Degradation, researchers from Lawrence Livermore…
LLNL scientists use controlled experiments to better understand nuclear fallout
In less than a millionth of a second after a nuclear detonation or a severe nuclear reactor accident, an enormous burst of energy heats the surrounding air and materials. Everything in the vicinity is vaporized into a hot, glowing cloud of gas and plasma. As that nuclear fireball expands, it mixes with air, begins to cool and condenses into tiny solid particles — creating…
HEDS Fellow John Copley’s modeling methodology
John Copley is the newest High Energy Density Science (HEDS) Center fellow at Lawrence Livermore. This fellowship provides him with the opportunity to independently pursue research related to the study of matter and energy in extreme conditions. In Copley’s case, this involves developing improved methods for modeling material phase transformations and equilibria at high…
Federica Coppari handles the pressure
There are several ways here on Earth to create the pressures and temperatures required to probe material behavior at extreme conditions, like those found in the interiors of stars and planets, for example. Federica Coppari, a research scientist in the Physics Division at Lawrence Livermore National Laboratory (LLNL), specializes in studying materials at the most extreme…
Three Lawrence fellows selected for 2026 cohort
This year’s three Lawrence fellows will pursue research that spans fusion science, emerging concepts for sensing and response and earth system science. Their work reflects both the breadth of Lawrence Livermore National Laboratory’s (LLNL) mission space and the program’s commitment to enabling early-career scientists to take bold, multidisciplinary approaches to…
Meet LLNL: Laser Material Interaction Deputy Group Leader Sonny Ly
Sonny Ly has built a career at Lawrence Livermore National Laboratory (LLNL) combining laser physics, materials science and mentorship. A deputy group leader in the Laser Material Interaction Science Group within the Materials Science Division under Physical and Life Sciences, Ly first came to the Lab in 2010 as a graduate student from the University of California, Davis…
Screening enzymes to break down plant waste and produce valuable biofuels
Locked away inside the walls of plant cells lies a valuable source of energy: sugar. But to access that sugar — which could provide a domestic source of bioenergy that strengthens U.S. energy security — researchers must first break down cellulose, the structural component of plant cell walls. A team at Lawrence Livermore National Laboratory (LLNL) has designed two high…
LLNL experts help advance inertial fusion energy at U.S. IFE conference
Researchers from Lawrence Livermore National Laboratory (LLNL) joined their counterparts from national laboratories, universities, industry and government in a conference last month to discuss the progress, challenges and priorities for moving toward an inertial fusion energy (IFE) future in the United States. The U.S. IFE conference brought together the growing IFE…
NASA's Roman telescope poised to transform hunt for elusive neutron stars
Astronomers have long known that neutron stars, the crushed cores left behind after massive stars explode, should be scattered throughout the Milky Way galaxy. However, most of them are effectively invisible. A new study published in Astronomy and Astrophysics suggests NASA’s upcoming Nancy Grace Roman Space Telescope could spot them anyway. Using detailed simulations of…
LLNL researchers, partnerships office earn technology transfer awards
The Federal Laboratory Consortium (FLC) has recognized the commercialization efforts of Lawrence Livermore National Laboratory (LLNL)’s researchers and Innovation and Partnerships Office (IPO) for the mission innovation impact of two Lab-developed technologies through a 2026 award and an honorable mention. IPO’s Business Development Executive (BDE) Yash Vaishnav and…
3D-printed interlocking electrodes demonstrate optimization potential for energy storage
Good electrochemical energy storage (EES) devices such as rechargeable batteries and supercapacitors can store a lot of energy and release it quickly, but these design goals are often at odds with each other. Using design optimization and 3D printing, a team led by engineers and scientists at Lawrence Livermore National Laboratory (LLNL) have overcome this tradeoff and…
Pandora mission images help prepare for exoplanet atmosphere observations
A symbolic milestone in the lead-up to mission-readiness: the Pandora Observatory transmitted its first engineering images from low-Earth orbit on Jan. 19, 2026. The CODA telescope, developed by a team of scientists and engineers at Lawrence Livermore National Laboratory (LLNL), in partnership with Corning Incorporated, captured an abstract portrait of the cosmos as it…
Revitalized laser technology captures commercialization grant
Small, modular nuclear fission reactors and fusion facilities could each be the future of resilient and secure energy in the U.S. and around the world. But these technologies rely on isotopes of lithium to cool fission reactors and create fusion fuel. Currently, there is no sustained, domestic production mechanism for lithium isotopes in the U.S. that meets projected…
Simulations predict ground motion for earthquakes on Bay Area’s Hayward fault
The Hayward fault, part of the larger San Andreas fault system, runs 74 miles through the East Bay of the San Francisco Bay Area. The fault is overdue for an earthquake that could cause extensive damage to such a dense population zone. In a recent study, published in Seismological Research Letters, scientists at Lawrence Livermore National Laboratory (LLNL) and Lawrence…
