Titans of Science continues with plant biologist Enrico Coen, a professor at the John Innes Centre in Norfolk. His work investigates how genes move and interact to create tissue shapes during plant development, and how this process varies to produce such a wide range of plant forms. In this episode, we find out how Enrico's early work on fruit flies paved his path to plants, and his work on 'jumping' genes and their effect on plant variation. He's been speaking with Chris Smith.

Malaria has been killing humans for at least fifteen thousand years, and our DNA still carries the scars. Ninety percent of the world's malaria cases are in Africa. But this isn't just a modern health crisis. It's written into our evolutionary history. New research from the University of Cambridge reveals that early humans actively avoided malaria hotspots across Africa for tens of thousands of years. The archaeological record is striking: mosquitoes thrived where people didn't live. Until something changed. Around fifteen thousand years ago, a genetic mutation emerged in West Africa: the...
