Are Viruses Alive? - Livestream

Countless scientists around the world study life, and yet they can't really agree on what it is. Are viruses alive, for example, or are they lifeless packages of protein and nucleic acid? Join New York Times columnist Carl Zimmer as he explores the boundaries of life, encountering viruses and other strange residents of the borderlands.

Copies of Carl's book, 'Life's Edge: The Search for What It Means to Be Alive' are available from amazon and all good bookshops.
