What is a paradox? How do you resolve them? Can they be resolved? This week Peter and Russell go through a number of popular paradoxes and try to figure out though a blend of humour and confusion if there is a way to solve them. Join us for another light hearted walk through the world of paradoxes and see if you come up with the same solutions.

This week Peter and Russell look at de-extinction. What leads animals to go extinct, what are the issues we need to consider about bringing them back from extinction and how would we do it anyway?

Did Jurassic Park get it right? Will we use dinosaur DNA found in amber? Can we bring back dinosaurs?

We all know about the first moon landing over 50 years ago, but what about the race to get there. It was just after World War II and the two biggest super-power's were battling it out to conquer space. This week Peter and Russell look at the achievements made during the cold war by the USA and the USSR. Even though each side won various milestones along the way, this rivalry would eventually lead to cooperation. But before that happened, there were many mishaps and some unsolved mysteries. We even have sound clips of key moments during the great space race, as well as some unexplained ones including what has been said to be the last words of a lost female Cosmonaut.
