About this episode

Bonnie Bassler discusses how bacteria communicate and cooperate through quorum sensing.

One of the characteristics of life is that living organisms gather information and put it to use. Even one of the simplest lifeforms, bacteria, are able to sense features of their surroundings and alter their behavior accordingly. Most impressively, they are able to sense the presence of similar bacteria by a process called quorum sensing . Today's guest, Bonnie Bassler, is a leader in this field, and explains how quorum sensing allows groups of bacteria to do things (including in our bodies) that wouldn't be possible for individual bacteria.
