Sheldon Paquin curated the Superbugs exhibition that's going on at the Science Museum in London at the moment, and Dan chats to him to find out what a superbug is and how they effect us. 

Plus, Professor Hallux chats about bones, we find out about the history of the earth with Finley and can you have fizzy drinks in space? Professor Pulsar and Captain T-Tauri find out!
