The use of embryonic stem cells has ignited fierce debate across the spiritual and political spectrum. But what if we could create manmade stem cells - or find super cells in adults that could forever replace embryonic cells and remove the controversy? Today, we are on the brink of a new era - an age where we may be able to cure our bodies of any illness. Stephen Hawking has spent his life exploring the mysteries of the cosmos, now there is another universe that fascinates him - the one hidden inside our bodies - our own personal galaxies of cells. Hawking takes us on a fascinating journey exploring what these wondrous and baffling mechanisms are capable of. He is joined by the scientists who are on the front lines of discovery in this field including Dr. Doris Taylor who is customizing a donor's heart with the recipient's stem cells - her goal is to revolutionize heart transplants, Dr. Paul Lu and Dr. Mark Tuszynski may have created a breakthrough that could cure paralysis, and Dr. Vincent Giampapa who believes that stem cells can be used to stem the tide of aging and create a fountain of youth.

Michael Mosley and James Wong explore the effect that our food has on our most important and, in terms of energy consumption, our greediest organ. It influences our diet by generating cravings for foods such as fat - the most energy-rich food of them all. James heads off to Peru to reveal the surprising link that fat-rich, indulgent chocolate has with breast milk. Sometimes these cravings almost become an addiction - like coffee for example. So we visit a remarkable lab where a team is studying the effect of caffeine on bees and how that may help explain the hold that caffeinated drinks have over us. Together, Michael and James take on some of the hottest chillies on the planet to show what the burn does to our brains. Using the latest imaging techniques and incredibly detailed specialist photography, this is a whole new way of thinking about our relationship with food and the powerful effect it has on our minds.
Psychopaths have long captured the public imagination. Painted as charismatic, violent predators lacking in all empathy, they provide intrigue and horror in equal measure. But what precisely is a psychopath? What is it that drives them to cause harm, even kill? And can they ever be cured? Presented by psychologist professor Uta Frith, this is an in-depth exploration of the psychopathic mind including one of the most notorious of all, Moors murderer Ian Brady. Through an ongoing correspondence between the Horizon team and Brady, the film features some of the very last letters he wrote. The film also features a series of candid interviews with prison inmates who not only describe their crimes but why they think they committed them. Horizon explores not only how each individual's crimes were shaped by their own life experiences, but also gives an insight into how these people think and behave. Working with the world's experts in the field, the film sheds light on the biological, psychological and environmental influences that shape a psychopath. And it looks to the future, with groundbreaking research that suggests a lifetime of incarceration is not the only option to manage violent and dangerous psychopaths.
