#120: DeepMind claims artificial intelligence breakthrough; searching for ancient life on Mars; Stonehenge surprise; monkeypox latest

DeepMind’s new artificial intelligence, Gato, is a step beyond anything we’ve seen before. But how close has it brought us to the coveted goal of creating ‘artificial general intelligence’? The team unpacks just how powerful this technology really is, and what it means for the future of machine consciousness. You can learn a lot from poop. In an archaeological detective story, 4500-year-old fossil excrement belonging to the people who built Stonehenge has been examined, and the team explains what it tells us about their eating habits.
