Could life on Earth have an extraterrestrial origin? The team revisits this ancient theory as we’ve now found all four of the key building blocks of DNA on meteorites that are older than our planet. There may be a warning signal in our brains that helps us keep out unwanted thoughts. The team hears about the fascinating word-pairing method researchers used to identify this mechanism, and how the f...

What is consciousness? We’ve discussed many theories on the podcast, but in this episode the team explores a particularly bonkers one. Experiments with anaesthetics have hinted that something might be going on at the quantum level with microtubules in the brain. But is this finding enough? Ever wondered what a rainbow sounds like? Or perhaps what sounds a rat’s whiskers would make if played like a...

Two teams are developing messages to send into space, in the hope that some advanced alien civilization will be able to pick them up. While METI is sending music, Beacon in the Galaxy is sending more complex information, like Earth’s location - which as the team explains is rather controversial… Acne is usually treated using antibiotics, but as the issue of antibiotic resistance grows, researchers...

The latest major report from the Intergovernmental Panel on Climate Change is out, and the message is clear. Time is running out to keep global warming to below 1.5 degrees. The report outlines the many ways we can make emissions cuts, one of which is through litigation. Hear from one of the report’s authors, Joana Setzer, who explores the growing use of legal action to challenge governments and c...
