Designing a nutritious and planet-friendly diet, and an AI that guides mathematicians.In this episode:00:46 Designing a healthy diet for the planetResearchers are trying to develop diets that help to reduce greenhouse gas emissions while at the same time providing nutrition. Some of these sustainable diets are now being tested to see if they work in local contexts without damaging livelihoods.Feature: What humanity should eat to stay healthy and save the planet08:24 Research HighlightsHow jellyfish get by without a centralised brain, and reading the runes within a medieval lead amulet.Research Highlight: How jellyfish control their livesResearch Highlight: Neutron beam sheds light on medieval faith and superstition10:32 The AI guiding mathematicians’ intuitionFinding relationships between two seemingly unrelated groups of objects is an important part of some branches of mathematics. To help speed up this process, a new AI has been developed, which points mathematicians towards potential relationships, allowing them to come up with new conjectures.Research article: Davies et al.News and Views: Artificial intelligence aids intuition in mathematical discovery11:23 Briefing ChatWe discuss some highlights from the Nature Briefing.
