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

Understanding the properties of the warm dense matter in planetary cores could help indicate if a planet could support life.

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

// 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

Data from NIF experiments (inset, right) and simulation (inset, left) are being combined with deep learning methods to improve areas important to national security and our future energy sector
// S&T Highlights
The detailed HPC design uses the world’s largest supercomputers and its most complicated simulation tools to help subject-matter experts choose new directions to improve experiments. CogSim then employs artificial intelligence (AI) to couple hundreds of thousands of HPC simulations to the set of past ICF experiments.
