#22: Consciousness from the body as well as the brain; record temperatures in the Arctic; long-term symptoms of covid-19

If your brain was put in a vat and supplied with food and oxygen, would it be able to think? Would it be you? For much of the 20th century, people assumed the answer to this thought experiment was yes. But there is growing evidence suggesting the brain needs the body to work properly, and even to create consciousness. 

In the pod this week are New Scientist journalists Rowan Hooper, Penny Sarchet and Catherine de Lange. They discuss whether artificial consciousness in a robot or computer is even possible if consciousness requires a body, and what this “embodied cognition” means for people with autism and post-traumatic stress disorder. 

In other stories, they hear about a whale without a tail, news of the world’s fastest supercomputer, and explore what the long term impact of covid-19 on people who caught coronavirus might be. The team also discuss the worrying news that the highest ever temperature (38°C) has been recorded in the Arctic. To find out more, subscribe at newscientist.com/podcasts.
