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…

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…

The AVLIS program began at LLNL in 1973 and was suspended in 1999. Now, the technology is being revived to create a domestic process for enriching lithium and fuel an energy-resilient nation.

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…

New protein-screening platform accelerates rare-earth separation for U.S. supply chain

To ensure a robust domestic supply chain in the U.S., Lawrence Livermore National Laboratory (LLNL) scientists are using bacterial proteins to separate the rare-earth elements that are ubiquitous in magnets, batteries and electronics. These proteins, called lanmodulin, evolved in bacteria that use rare-earth elements to power their metabolism. But to scale up and advance…

The Joint Actinide Shock Physics Experimental Research (JASPER) facility at the Nevada National Security Site uses a two-stage gas gun to study plutonium under extreme conditions.

Big Ideas Lab podcast explores JASPER and the science of measuring plutonium under extreme conditions

In less than a microsecond, a projectile traveling thousands of meters per second strikes its target, generating pressures and temperatures too extreme to observe directly. At Lawrence Livermore National Laboratory (LLNL), scientists use that moment to answer complex questions for national security. The latest episode of the Big Ideas Lab podcast takes listeners to the…

LLNL to harness quantum computing for next-generation magnets

Lawrence Livermore National Laboratory (LLNL) has been selected to lead a project that will receive $4.1 million in funding from the U.S. Department of Energy Advanced Research Projects Agency-Energy (ARPA-E) as part of the Quantum Computing for Computational Chemistry (QC3) program. QC3 seeks to develop and apply quantum algorithms to accelerate simulations of chemistry…

Adding an optimized void structure (top right) counteracts a shockwave-induced instability, reducing jetting (bottom right) that can interfere with inertial confinement fusion. Without this void, significant jetting occurs (bottom left). (Image: Strucka et al.)

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…

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…
