What Is Life? A Podcast Series

As a science writer, I report in articles and books about the many wondrous forms life can take, from brilliant cephalopods to cunning viruses. But sometimes I stop and wonder about life itself. What is it? How do we define it? How do we know it when we see it? Why does it exist at all?

To explore these questions, I hosted a series of live conversations with some leading thinkers on life—including chemists, physicists, and a philosopher — at Caveat in New York City. You can now listen to all eight episodes of “What Is Life?” on iTunes, Libsyn, or wherever you get your podcasts (RSS). If you like it, please rate and review it so others can find out about it too. Thanks!
