DNA pioneer Jim Watson is the subject of much of our show today - he's been raising hackles by making comments on race and genetics and we pick over the bones of last week's furore with Imperial College geneticist, Armand Leroi.
Armand helps us to grapple with the the two big questions that came out of Watson's comments and the world's reactions to them: is there any evidence that intelligence is linked to race and how far should scientific debate be allowed to go?
Guardian science correspondent Ian Sample reports from last week's annual meeting of the American Society for Reproductive Medicine - he reveals why women shouldn't freeze their eggs to use in future.
The Newsjam features one of the biggest dinosaurs ever found, a claim for 1m square kilometres of the Antarctic by Britain, and GM poplar trees that can suck up pollution from the soil.
We've also got the final part of our series of conversations with biologist Craig Venter. This week he tells the Guardian's Ed Pilkington about the genome wars, where Venter took on the scientific establishment in a race to sequence the human genome. Parts one and two are also still available.
In the pod this week, Alok Jha is joined by James Randerson, Nell Boase and producer Mat Heywood.
