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.
In the US, 80% of girls have been on a diet by the time they're 10 years old. In this honest, raw talk, neuroscientist Sandra Aamodt uses her personal story to frame an important lesson about how our brains manage our bodies, as she explores the science behind why dieting not only doesn't work, but is likely to do more harm than good. She suggests ideas for how to live a less diet-obsessed life, intuitively.
Since 2003, human DNA has been completely decoded. Scientists are currently working on decoding all of the body's own proteins, the so-called Proteom code - this process is almost complete. From the results, medicine hopes new findings in the search for drugs against cancer, infections, and disease.

The Ebola virus. No-one knows exactly where it comes from but one thing is certain - it's one of the most virulent infections known to science. This special episode of Horizon meets the scientists and doctors from all around the world looking for the cure and hears first-hand accounts of what it's actually like to catch - and survive - this terrible disease.
Episode 2 – exposes how the industrial revolution opened the floodgates for highly-processed convenience foods that became "our daily bread." But those pseudo-grains are known to contribute to chronic disease. Natural, whole grains support longevity and lower the risk of heart disease. Grain of Truth also explores the debate over gluten as a dietary evil.
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.
