Do dolphins have their own language ? And could we 'speak' to them ? An AI large language model from Google, called DolphinGemma, is helping experts study dolphin communication. We interview Doctor Denise Herzing, the Research Director and founder of the Wild Dolphin Project, about her work and how it might bring benefits for humans and dolphins.

Also in this edition, we find out how tech is changing the way NFL fans watch football games, and mega-batteries are helping to keep the lights on.
