As the show that takes your questions and turns them into audio adventures reaches its 100th episode, Marnie Chesterton revisits a few of our most liked, talked-about, and inbox-filling programmes to find out how science is getting on with the answers. Marnie heads to a place where important queries have been tackled for hundreds of years - the University of Cambridge in the UK - to chase down some burning follow-ups on topics that have piqued your interest. She finds out what the future holds for the next generation of batteries as they're expected to power everything from smart phones to your car and even your house. Then she scrubs up to tackle your tough questions on the best ways to keep clean. Finally, Marnie visits a memory laboratory at Cambridge University to discover whether the very process of asking questions might be one way to help us remember more.
