#111: Antarctic and Arctic record-breaking heat; octopus brains insight; black hole paradox explained

Extreme weather events have been recorded at both of Earth’s polar regions, as the Arctic and Antarctic are hit by major heat waves. To put this into context, Rowan speaks with climate scientist and Hot Air author Peter Stott.How did octopuses get to be so clever? Their intelligence is unusual for an invertebrate, so researchers have been trying to track down what’s going on in their brains. The team examines new findings which suggest it has something to do with microRNAs.Black holes have always been mysterious, but a problem known as the ‘black hole paradox’ has been bothering physicists because it undermines what we know about quantum mechanics. Now, as the team explains, there could be a (vaguely confusing) solution. They also mark a major milestone in the search for new exoplanets.The team reviews a compelling new sci-fi opera that’s showing in New York. Upload is about a daughter who is trying to come to terms with the decision of her father to physically die in order to have his consciousness uploaded to a computer.And we hear the *delightful* sound of an orangutan ‘kiss squeak’, as the team finds out what this vocal call tells us about the evolution of speech in primates.On the pod are Rowan Hooper, Penny Sarchet, Leah Crane and Timothy Revell.

#103: How covid affects brain function; glacier loss on Svalbard; start of the Anthropocene; hottest life on Earth

Covid-19 can have profound consequences for the brain, and now we’re beginning to understand why. The team explains how the virus causes issues from strokes to muscle-weakness and brain-fog. We have names for all of Earth’s geological phases, and right now we’re in the Anthropocene… or are we?
