ORNL has added 10 virtual tours to its campus map, each with multiple views to show floor plans, rotating dollhouse views and 360-degree navigation. As a user travels through a map, pop-out informational windows deliver facts, videos, graphics and links to other related content.

Sandra Davern performs cell based assays to evaluate cell death and DNA damage in response to radiation in order to gain a better understanding of how radioisotope nanoparticles affect the human body.

When Sandra Davern looks to the future, she sees individualized isotopes sent into the body with a specific target: cancer cells.

The first neutron structure of the SARS-CoV-2 main protease enzyme revealed unexpected electrical charges in the amino acids cysteine (negative) and histidine (positive), providing key data about the virus’s replication. Credit: Jill Hemman/ORNL, U.S. Dept. of Energy

To better understand how the novel coronavirus behaves and how it can be stopped, scientists have completed a three-dimensional map that reveals the location of every atom in an enzyme molecule critical to SARS-CoV-2 reproduction.
