World War II bombs were defused in Cologne, Germany, which has inspired us to explore the science of diffusion and defusing!First, we hear how new, artificially intelligent video generators are modelled on diffusion. We also hear about the health impacts of home aroma diffusers and candles. We’re joined by conflict-mediator Gabrielle Rifkind of the Oxford Process, to discuss the psychological stakes behind defusing conflict in wars and at home.We also taste-test the difference between raw and cooked broccoli, learn about in-insect synthesis, and explore an anechoic chamber. All that, plus many more Unexpected Elements.

Presenter: Caroline Steel, with Tristan Ahtone and Edd Gent
