Scientists uncover a clever ranking strategy bacteria use to fight off viruses

Scientists uncover a clever ranking strategy bacteria use to fight off virusesLike humans, bacteria come under attack from viruses—and their immune systems, like ours, are capable of remembering a virus so as to preempt any future invasion. New research explores how the bacterial immune system CRISPR stores and ranks these memories. More »

Virus-cutting enzyme helps bacteria remember a threat

Virus-cutting enzyme helps bacteria remember a threatThe enzyme Cas9 is well known for its ability to make precise cuts in a genome. New research reveals a new role for Cas9 in its native bacteria: helping the microbial immune system acquire a memory of an invading virus. More »

Howard Hang promoted to associate professor

Hang, a chemist who works to develop new tools for the study of host-pathogen interactions, has discovered that many proteins involved in host immunity to viruses and bacteria are regulated by fatty acid modifications.
