In this podcast, I talk to Susan Golden, the co-director of the Center for Chronobiology at the University of California at San Diego.

We talked about Golden's research into time--in particular, how living things know what time it is. While you may have heard of our own "body clock" that tracks the 24-hour cycle of the day, it turns out that some bacteria can tell time, too. Golden has discovered how evolution has produced a molecular clock inside microbes far more elegant than any manmade timepiece.
