"A pretty cool paper." That's how one of the hosts of the This Week in Microbiology podcast (ep. 159) describes the recent study by School of Biological Sciences professor Joshua Weitz and postdoctoral scientist Chung Yin (Joey) Leung. The Tech researchers discovered that immune cells in an animal host act synergistically with bacteria-killing viruses – phages – to wipe out fatal respiratory infections in lab mice. TWiM is the official podcast of the American Society for Microbiology. Both Weitz and Leung are also affiliated with the School of Physics, and Weitz is the founding director of the Interdisciplinary Graduate Program in Quantitative Biosciences.
