Aral Slotter, a researcher from the University of Marine Research in Norway, and David Adam, a writer focusing on AI's impact on mental health, dive into intriguing subjects. They discuss how selective fishing has disrupted herring migration, leading to a loss of traditional spawning knowledge among younger fish. This has implications for ecosystem health. They also explore the rise of AI companions, addressing their emotional benefits and the challenges these relationships pose for mental well-being and social skills.

In this episode:00:46 What will be left of US science after Trump 2.0?100 days into his term, President Donald Trump and his administration have already caused the biggest shakeup in modern scientific history, slashing funding, bringing large swathes of US research to a standstill and halting many clinical trials. But many fear these actions are just the beginning. We look at what the long-term impacts of these decisions might be for science in the United States and the world.Nature: Will US science survive Trump 2.0?13:42 Research HighlightsA distant planet that orbits two stars, at a right angle, and how fringe-lipped bats’ hearing helps them find palatable amphibians.Research Highlight: ‘Tatooine’-like planet orbits two stars ― but at a weird angleResearch Highlight: For these bats, eavesdropping is a valuable learnt skill16:07 Briefing ChatThe first skeletal evidence from bones that Roman gladiators fought lions, and scientists finally pinpoint the genes responsible for three of the pea traits studied by Gregor Mendel.BBC News: Bites on gladiator bones prove combat with lionNature: Century-old genetics mystery of Mendel’s peas finally solvedSubscribe to Nature Briefing, an unmissable daily round-up of science news, opinion and analysis free in your inbox every weekday.
