Survey of New York City soil uncovers medicine-making microbes

Survey of New York City soil uncovers medicine-making microbesSifting soil from city parks, scientists have found microbial genes capable of making compounds whose potent effects can make them valuable tools in the fight against disease. Their research suggests that many more await discovery, even in a place as mundane as urban dirt. More »

Study explains how an intestinal microbe protects against other, more dangerous bacteria

Worm Cross Section ThumbnailWorking in animal models, scientists have found that an enzyme produced by one microbe can shield the gut against attack from other, more harmful bacteria. The findings could potentially inform the design of new probiotics for use against dangerous pathogens like those spreading hospital-acquired infections. More »

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.
