  • Summary

  • Episode 269 Could we re-freeze the Arctic… and should we? The Arctic is losing ice at an alarming rate and it’s too late to save it by cutting emissions alone. Geoengineering may be our only hope. A company called Real Ice has successfully tested a plan to artificially keep the region cold - but what are the consequences and will it work on the scale we need? Octopuses and fish have been found hunting together in packs in an unexpected display of cooperation. Not only do the fish scout out potential prey, they even signal to the octopuses to move in for the kill. And a fish doesn’t prove helpful? They get punched. The world’s oldest cheese has been found in China - and it’s 3,500 years old. As we get a fascinating look into the fermenting habits of ancient humans, find out how modern day fermentation is being repurposed to help us create biofuels, break down microplastics and more. We hear from Tom Ellis, professor of synthetic genome engineering at Imperial College London. Our bodies are littered with microplastics - they’re in our livers, kidneys, guts and even our olfactory bulb. How worried should we be? Microplastics have been linked to some pretty serious health consequences - but are they the cause? Hosts Rowan Hooper and Sophie Bushwick discuss with guests Madeleine Cuff, Michael Le Page and Grace Wade.
