Meet The Microbiologist - The Scientists Behind The Microbiology

Dennis Bray is an active professor emeritus in both the Department of Physiology and Department of Neuroscience at the University of Cambridge. He studies the behavior of microbes--how they "decide" where to swim, when to divide, and how best to manage the millions of chemical reactions taking place inside their membranes. For Bray, microbes are tiny, living computers, with genes and proteins serving the roles of microprocessors. In this interview, I talked with Bray about his provocative new book, Wetware: A Living Computer Inside Every Cell.
