Podcast: Wildfires, climate action tipping points, and helping stroke patients

In this edition: Art-science collaborations around wildfire research, joining the climate fight, and an app to aid stroke rehabilitation. News: New test for eye disease – We learn about a new AI-led test for a debilitating eye disease that can cause blindness, and how warming temperature may affect bumblebees' flight. The art and science of wildfires – We hear about a series of workshops that brought together scientists and artists, who found differences but also surprising similarities between their approaches to studying – and sharing – the world of wildfires, both devastating and beneficial. Tipping points – What motivates people to study and fight climate change? PhD student Peter Knapp talks to scientists who have joined the Extinction Rebellion movement, and we've got a preview of some of his interviews. You can listen to the full interviews in the Tipping Points podcast. On track for stroke rehabilitation – We meet the makers of an app to help patients recover the activity of their arms following a stroke, and hear how the platform is already helping people make progress and build confidence.
