Designing a nutritious and planet-friendly diet, and an AI that guides mathematicians.
In this episode:
00:46 Designing a healthy diet for the planet
Researchers 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 planet
08:24 Research Highlights
How jellyfish get by without a centralised brain, and reading the runes within a medieval lead amulet.
Research Highlight: How jellyfish control their lives
Research Highlight: Neutron beam sheds light on medieval faith and superstition
10:32 The AI guiding mathematicians’ intuition
Finding 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.
