Over 400 million cups of coffee are consumed daily in the United States alone. Making coffee one hot drink, even when served cold. Experts reveal what makes your specialty coffee taste the way it does.
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.

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?

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.
