Experiments using a giant wave machine test how salt marshes protect shorelines during extreme storms. The episode also explores evidence about Denisovan faces, orangutan mothers arranging play encounters, and the unequal effects of medieval lead exposure.

Mariana Kneppers, Mason Wakley and Jamie Durrani revisit the Seveso chemical disaster and its lasting health and regulatory consequences. They also discuss membrane materials designed to separate hydrocarbons with less energy than conventional refinery processes, connecting materials research to industrial efficiency.

The conversation connects environmental toxicology with international negotiations on a plastics treaty and considers how changes in plastic production and use could address pollution.
