Something in the Water Does Not Compute

Computational scientists at the Department of Energy’s Oak Ridge National Laboratory have published a study in the Journal of Chemical Theory and Computation that questions a long-accepted factor in simulating the molecular dynamics of water: the 2 femtosecond (one quadrillionth of a second) time step. The femtosecond is a timescale…

Summit Helps Forge Stronger Flights

Titanium alloys serve as cornerstone materials for the aerospace industry — stronger and lighter than steel, resistant to rust and corrosion and resilient past the melting points of most other metals. Companies such as RTX, formerly Raytheon Technologies, rely on these sturdy alloys to build such vital machinery as jet-engine turbine…

Planning for a Smooth Landing on Mars

A U.S. mission to land astronauts on the surface of Mars will be unlike any other extraterrestrial landing ever undertaken by NASA. Although the space agency has successfully landed nine robotic missions on Mars since its first surface missions in 1976 with the Viking Project, safely bringing humans to Mars…

Exascale’s New Frontier: E3SM-MMF

PI: Mark Taylor, Sandia National Laboratories In 2016, the Department of Energy’s Exascale Computing Project (ECP) set out to develop advanced software for the arrival of exascale-class supercomputers capable of a quintillion (1018) or more calculations per second. That meant rethinking, reinventing, and optimizing dozens of scientific applications and software…

Fungal ‘Bouncers’ Patrol Plant-Microbe Relationship

By Stephanie Seay, ORNL A new computational framework created by Oak Ridge National Laboratory researchers is accelerating their understanding of who's in, who's out, who’s hot and who's not in the soil microbiome, where fungi often act as bodyguards for plants, keeping friends close and foes at bay. The research…
