A team of scientists led by the Department of Energy’s Oak Ridge National Laboratory and the Georgia Institute of Technology is using supercomputing and revolutionary deep learning tools to predict the structures and roles of thousands of proteins with unknown functions.

In October, a scientist whose research was supported by modeling and simulation efforts on supercomputers at the US Department of Energy’s Oak Ridge National Laboratory shared the Nobel Prize in Chemistry 2021.

A team used the Summit supercomputer at Oak Ridge National Laboratory to model plasma turbulence in a nuclear fusion device to capture energy loss in fusion plasmas. The team’s simulations will help inform the design of next-generation tokamaks like ITER with optimum confinement properties.

This feature provides an overview of the science behind the discovery of superheavy elements and outlines ORNL's crucial role in supplying actinide target materials.

With multiple clinical trials under way, it’s likely both a drug using Ac-225 and increased demand for the radioisotope are in the near future — and the U.S. Department of Energy wants to be ready. Since 2015, DOE’s Isotope Program has sponsored the Tri-Lab Effort to Provide Accelerator-produced Ac-225 for Radiotherapy. Thorium-232 targets are irradiated in proton accelerators at Los Alamos and Brookhaven national laboratories, then sent to ORNL for processing in hot cells dedicated to alpha radiation. The purpose: producing bigger batches, faster. In June, ORNL processed the largest batch of Ac-225 ever put in inventory.

A team of collaborators from the U.S. Department of Energy’s Oak Ridge National Laboratory, Google Inc., Snowflake Inc. and Ververica GmbH has tested a computing concept that could help speed up real-time processing of data that stream on mobile and other electronic devices.

A team has used machine learning descriptions of interatomic interactions on the 200-petaflop Summit supercomputer at ORNL to model more than a billion carbon atoms at quantum accuracy and observe how diamonds behave under some of the most extreme pressures and temperatures imaginable.

Scientists used the nation’s fastest supercomputer to peer inside the intricacies of how the SARS-CoV-2 virus reproduces itself.

A team of scientists from the U.S. Department of Energy’s Oak Ridge National Laboratory used the nation’s fastest supercomputer to streamline the search for potential treatments for COVID-19.

A team led by Rommie Amaro of the University of California San Diego has used ORNL’s Summit supercomputer to model an aerosolized SARS-CoV-2 viral particle for the first time. The 1.05-billion-atom system is among the largest biochemical system ever simulated at the atomic level.
