The Bright Ideas Challenge was created to help inspire the next generation of scientists and engineers. Bobby Seagull & Emma Wyatt are on the line with Dan to chat all about how we could power the cities of the future and the brand new findings that show that kids think they are the key to changing the world for the better through Science. 

Plus Dangerous Dan is discovering a tiny single-celled organism that will eat your brain, we find out why Barcelona shakes from time to time and we're pitching carnivores and herbivores against each other in the Age of the Dinosaurs!
