Cross Section: Paul Davies – Science Weekly podcast

Nicola Davis talks to the theoretical physicist Paul Davies, who has been trying to find the solution to one of humankind's trickier questions - what is life?

Paul joins Nicola in studio to talk about his new book The Demon in the Machine. In it, he looks at whether or not we have all of the tools necessary to come up with answer to what life actually is. He suggests we may need something fundamentally new - a field yet to be discovered - to answer this question.

The pair discuss everything from Margaret Thatcher to dead mice.
