In a special programme to mark, amongst other things, the centenary of Albert Einstein's General Theory of Relativity, Adam Rutherford is joined by The Film Programme's Francine Stock to explore the theme of time-travel - in science, in film and as film. With studio guest, science writer Marcus Chown, they'll discuss time-machines - as imagined by scientists and film-makers; the grandfather of all paradoxes; the notion of the multiverse and how the pioneers of cinema created their own 'time-machines' through the art of editing. And to mark Back the Future Day, otherwise known as 21 October 2015, they talk to director Robert Zemeckis about how and why he imagined a future with hover-boards but, oddly, no smart phones.Producers: Stephen Hughes and Rami Tzabar.

As evidence grows about the vulnerability of our ocean corals to climate change, what's often overlooked are the more subtle changes in the ocean waters that contribute to coral resilience. Adam visits Southampton's Oceanography Centre where new research is showing how an imbalance of nutrients in reef waters is increasing the vulnerability of reef corals to high water temperatures which could help direct future coastal management.The long awaited hunt for gravitational waves gets underway as the Laser Interferometer Gravitational Wave Observatory (LIGO) in the United States begins its first observational run. The waves, generated by some of the most dramatic events in space such as the explosion of stars and the merging of two black holes, were first postulated by Einstein in 1916. So far they've never been detected but if LIGO is successful it'll not only provide proof of Einstein's Theory of Relativity but also provide the first direct evidence of the existence of black holes.And Adam meets theoretical physicist Carlo Rovelli whose new book Seven Brief Lessons on Physics examines in seven short essays how 20th century physics is shaping our world view. In Italy, it's outsold 50 Shades of Grey and the Pope's Encyclical and has now been translated into English. What's been the key to its success?

A special edition recorded in front of an audience at Write on Kew, the Royal Botanical Garden's new literary festival. Adam Rutherford examines the science behind the global challenges and innovative solutions to preserving the essential biodiversity of the planet. From new perspectives on how plant populations can be made more resilient, to the remarkable genetic diversity of plants just being revealed by new analytical techniques, to coffee - and how one of our most prolific yet threatened commodities be protected from a changing climate . Do we need a radical new approach - are the large scale climate fixes offered by geoengineering the right solution? Adam Rutherford is joined by panellists: Kew's Director of Science, Kathy Willis; evolutionary botanist, Ilia Leitch, Kew's research leader in plant resources, Aaron Davis and author Oliver Morton.Producer: Adrian Washbourne.
