Helping Science Weekly to celebrate its second birthday this week, environment writer Fred Pearce joins Alok Jha and James Randerson in the pod. Fred's latest book concerns his mission to find out where all of our 'stuff' comes from. But if you think you're about to be subjected to an aural assault of environmental worthiness, fear not. As Fred says, "I'm not a tree-hugger. I'm a humanist. I just want solutions that place people at the centre of things."
Also in the podcast, we analyse the biofuels and embryology debates that have seen scientists and politicians lock horns over the past fortnight. Michio Kaku explains teleportation and the physics of the impossible. We hear why people in Russia just adore an April Fool's joke. And finally, we listen to the oldest sound recording ever made.
