X-rays size up protein structure at the “heart” of COVID-19 virus

A team of researchers at the Department of Energy’s Oak Ridge and Argonne national laboratories has performed the first room-temperature X-ray measurements on the SARS-CoV-2 main protease, the enzyme that enables the virus to reproduce.

The X-ray measurements mark an important first step in the researchers’ ultimate goal of building a comprehensive 3D model of the enzymatic protein.

General Chair’s Special Session: Advanced reactors in uncertain times

The final plenary session of the American Nuclear Society's 2020 Virtual Annual Meeting was the General Chair’s Special Session, held on Wednesday, June 10. The session contained much information about the current and future role of advanced reactor technology. The session, with the subtitle “The Promise of Advanced Reactors during Uncertain Times: National Security, Jobs and Clean Energy,” featured two panels: the Lab Directors Roundtable and the Advanced Reactor Panel. The general chair is Mark Peters, Idaho National Laboratory director. The session was moderated by Corey McDaniel, of Idaho National Laboratory, and the assistant general chair of the Annual Meeting.

A few of the issues covered during the dual plenary session included challenges to advanced reactor deployment, public-private partnerships in research and development, nuclear non-proliferation and security, workforce issues, and market conditions and demand.
