Science and Technology Highlights

Empirical measurements of carbon and nitrogen exchange between algae and bacteria, using stable isotope tracing, allowed the LLNL team to identify three different bacteria types with distinct ecological roles, providing a conceptual framework to better understand how the algal microbiome plays a role in carbon and nitrogen degradation and recycling.

In a significant stride toward implementing scalable climate solutions, LLNL scientists have uncovered how some carbon capture materials have improved lifetime compared to others. These materials are key in addressing greenhouse gas emissions and global warming concerns.
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.
// S&T Highlights
Research by LLNL and collaborators from Carnegie Mellon University demonstrates that crystal structure prediction is a useful tool for studying the various ways the molecules can pack together, also known as ubiquitous polymorphism, in energetic materials.

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.

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
