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…

Closely Spaced Hydrogen Atoms Could Facilitate Superconductivity in Ambient Condition

By: Paul Boisvert, 502-229-4466, [email protected] An international team of researchers has discovered the hydrogen atoms in a metal hydride material are much more tightly spaced than had been predicted for decades—a feature that could possibly facilitate superconductivity at or near room temperature and pressure. Such a superconducting material, carrying electricity…

A New Parallel Strategy for Tackling Turbulence on Summit

Turbulence, the state of disorderly fluid motion, is a scientific puzzle of great complexity. Turbulence permeates many applications in science and engineering, including combustion, pollutant transport, weather forecasting, astrophysics, and more. One of the challenges facing scientists who simulate turbulence lies in the wide range of scales they must capture…

In the Mix

by Sara Shoemaker Mixing metals into alloys is an age-old practice. The tedious trial and error of heating, cooling, testing, and remixing was once the only method to fine-tune the best blend of metals for ideal strength and durability. In recent times, computational scientists have developed a faster, more precise…

Introducing Summit

The biggest problems in science require supercomputers of unprecedented capability. That’s why the US Department of Energy’s Oak Ridge National Laboratory (ORNL) launched Summit, a system 8 times more powerful than ORNL’s previous top-ranked system Titan. Summit is providing scientists with incredible computing power to solve challenges in energy, artificial…
