Senior Laboratory leaders attend a celebration marking the Scorpius accelerator milestone.
// S&T Highlights
Members of LLNL’s Advanced Sources and Detectors (ASD) Scorpius accelerator team recently marked a major milestone in the project — the delivery of 24 line-replaceable units (LRUs), known as pulsers, forming a complete unit cluster.
The figure shows the energy ranking, where lower energy means higher stability, as a function of density for the most stable crystal structures generated by the algorithm.

A new study provides surprising behavior of hydrogen bonding of water confined in carbon nanotubes.

A large portion of Greenland melted about 416,000 years ago — perhaps a bit like the small melt pond shown in this modern Greenland landscape — and became ice-free tundra or a boreal forest.
// S&T Highlights

A large portion of Greenland was an ice-free tundra landscape — perhaps covered by trees and roaming wooly mammoths — in the recent geologic past (about 416,000 years ago), according to a new study in the journal

Understanding the properties of the warm dense matter in planetary cores could help indicate if a planet could support life.
// S&T Highlights

To learn about the properties of materials under changing temperatures and pressures, researchers typically combine laboratory experiments with theoretical models and computer simulations.

LLNL scientist holds a 5-centimeter metasurface optic with deep, closely spaced surface features that allow for a wide optical bandwidth.
// S&T Highlights

Optics researchers at Lawrence Livermore National Laboratory (LLNL) have refined their novel metasurface process to create taller features without increasing feature-to-feature spacing, an advance that unlocks exciting new design possib
