What actually is in our blood? Why can Cheetahs run so fast? Author Paul Ian Cross joins us to chat all the grossest things about the body from is book Bodies, Brains and Bogies. In Science in the News this week we learn about the first rocket NASA has launched outside of the USA, a spacecraft being built in the UK and a new secret we have learnt from cavemen bodies that are 1 million years old! Hallux joins us again but its all about your teeth in this series at the dental depository, and Techno Mum has her knowledge tested in Techno Mum's Tech Trivia. And in Dangerous Dan its all on the fearsome Bowmouth Guitarfish! See omnystudio.com/listener for privacy information.
