Science and Technology Highlights

Lawrence Livermore National Laboratory and Pacific Fusion leaders and researchers gather around the SIRIUS pulsed-power prototype during a May 15 celebration marking the system’s 3,000-shot milestone at LLNL.
// S&T Highlights
A pulsed-power prototype designed and built at LLNL has surpassed 3,000 shots, a milestone researchers say demonstrates the maturity of a new accelerator architecture and marks an important step in evaluating how the technology could be scaled for future national and economic security applications, including fusion energy.
LLNL researchers examined how integrating molecular dynamics simulations with physics-informed machine learning can illuminate the relationships between chemistry, microstructure and behavior in complex battery materials.
// S&T Highlights
In two recent publications, LLNL researchers examined how integrating molecular dynamics simulations with physics-informed machine learning can illuminate the relationships between structure and behavior in complex battery materials.
A honeybee queen surrounded by her retinue, which is an ever-changing group of worker bees charged with her care, feeding and protection. The fuchsia spot is applied to queen bees to make them easier to identify.
// S&T Highlights
LLNL and U.C. Davis researchers showed that a honeybee queen facing chronic exposure to pesticides will take up that contamination and pass it along to her eggs, a process called maternal offloading.
LLNL scientists Dylan Kline (front) and Justin McAlister evaluate finished, mock high-explosive materials produced using a modern pharmaceutical manufacturing process called extrusion-spheronization.
// S&T Highlights
A team of researchers at LLNL is working on an initiative called Project MAHEM — A Modern Approach to HE (high explosive) Manufacturing — to address those weaknesses by building a stronger scientific foundation for explosive formulation and pressing.
Experiments at the National Ignition Facility used direct laser-driven compression of iron to pressure-temperature conditions relevant to Earth’s inner core, with x-ray radiography and VISAR diagnostics.
// S&T Highlights
Researchers from LLNL and several universities used the National Ignition Facility (NIF) to recreate extreme temperature and pressure conditions of the Earth’s inner core. This enabled the first ever simultaneous measurement of iron’s dynamic strength at relevant temperature and pressures.
LLNL researchers studied viruses in grassland soil before and after rapid rewetting. Most remained inactive, with only 22 percent of viruses replicating.
// S&T Highlights
A new study published in mSystems by researchers at LLNL shows that of the many viruses present in soil, only some are active participants at any given time. Over three quarters of the viruses in the study were dormant lurkers, persisting in the soil and biding their time for suitable conditions to emerge.
With specialized beamsplitters and precision freeform optics, scientists have generated a novel high-intensity laser that rotates like a spring.
// S&T Highlights
In new research published in Nature Photonics, scientists from LLNL and the University of California, Irvine demonstrated the first high-intensity “light spring” laser.

// S&T Highlights
Research, conducted by scientists at LLNL, the University of California, Berkeley, the French Commissariat à l’Énergie Atomique et aux Energies Alternatives (CEA) and the University of Rochester’s Laboratory for Laser Energetics (LLE), shows that helium reacts differently from the predictions of most broad-range theoretical models.
A collaboration of Lawrence Livermore National Laboratory, Sandia National Laboratories, Los Alamos National Laboratory and the Kansas City National Security Campus, Aires Tide brings together expertise across design, manufacturing and flight testing in a single cross-enterprise effort.
// S&T Highlights
LLNL is contributing AI-enabled payload optimization and advanced modeling and simulation expertise to Aires Tide, a collaborative National Nuclear Security Administration (NNSA) demonstration exploring new ways to design flight test vehicles.
In an inertial confinement experiment on the National Ignition Facility, the lasers converge at tiny entrance holes at the top and bottom of the hohlraum. The intersection of the lasers enables crossed-beam energy transfer, an important factor in maintaining symmetry of implosions.
// S&T Highlights
LLNL scientists have calculated that small changes in wavelengths would make NIF optics more resilient to filamentation damage.
