ZME Science (July 19) -- It took two years, two supercomputers and two Illinois researchers, Juan Perilla and the late Klaus Schulten, to simulate 1.2 microseconds in the life of an HIV capsid, a protein cage that protects the viral genome. The findings, reported in the journal “Nature Communications,” indicate several properties that enhance the capsid’s adeptness at finding a path to the nucleus of a target cells, but also potential vulnerabilities that could be exploited to defeat the HIV virus.
