This Nature Podcast episode discusses telephone tutoring during school shutdowns and what changing world-map projections could mean for atlases. Research highlights cover synchronized optical clocks and greenhouse-gas emissions from pigs. The publisher provides the episode audio on Acast.

Toni Lyn Morelli and Alexej Sirén discuss how climate change alters the geographical distribution of species. As habitats change, movement can offer plants and animals a route to persistence, but it also reshapes ecological relationships. The episode examines these shifts and their implications for conservation and the communities that share affected environments.

Carina Hoorn examines how the Amazon Basin’s geological evolution shaped its extraordinary biodiversity. The discussion connects Andean uplift, fresh sediment supply and marine incursions during the Early Miocene with the diversification of aquatic environments and ecological opportunities.

Vic Baker investigates megafloods, catastrophic events that differ from ordinary weather-driven flooding. He discusses proposed mechanisms and the geological evidence left by exceptionally large flows, including the Channeled Scablands of Washington State and the Mediterranean. The episode connects landscape interpretation with reconstruction of past extreme events.
