Defuse and diffuse

We鈥檙e spreading diffusion science after World War II bombs were defused in Cologne, Germany.

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鈥檙e 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
Producer: Imaan Moin, with Alice Lipscombe-Southwell, Minnie Harrop and Debbie Kilbride
