What is life? Bridging the disciplines to solve unanswered questions

For generations, scientists have struggled to make sense of the fundamental question: ‘what is life?’ Even a humble bacterium accomplishes things so dazzling that no human engineer can match it, and huge advances in molecular biology over the past few decades have served only to deepen the mystery. So, can life be explained by known physics and chemistry, or do we need something fundamentally new? In this podcast, Dr Raj Persaud discusses these thought-provoking questions with renowned physicist Professor Paul Davies – author of the 2019 book The Demon in the Machine.
