Bridges Helps Quantum Chemists Understand Break-up of Atmospheric Chemicals

The U.S. Air Force would like to detect remotely when bad guys have fired a rocket. They’d also like, in an emergency, to seed the atmosphere to damp down communication disruptions from solar flares. To better understand the very different chemicals involved in these two problems, quantum chemist Peter B. Armentrout and his team at the University of Utah turned to the XSEDE supercomputers Bridges at PSC and Comet at San Diego Supercomputer Center.

Simulations Show how HIV Drug Traps Virus in an Inactive State

Though AIDS survival is up and new cases are down, the HIV virus is still a major cause of sickness and death. Juan Perilla of the University of Delaware and his colleagues used the Anton 2 system at the Pittsburgh Supercomputing Center to understand better how HIV “matures” to its active state. They found that a class of anti-AIDS drugs may work by locking the virus in its immature form, suggesting a route toward new treatments.
