Gloria and Chris settle the argument over whether tea and coffee are good or bad for us - and if the same is true for both. There is also the truth about a food often touted as a way to fight cancer. And, after reports suggesting reusing plastic water bottles is a bad idea, tests reveal if we should be using a fresh one every time.
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.

For thousands of years, we’ve regarded sleep as nothing more than an annihilation of consciousness. But there is one compelling fact that has always stood in the way of that view. “Even the Greek philosophers wondered why we needed to sleep,” says neuroscientist, Dr. Kenneth Wright. “If sleep wasn’t important, it’s probably one of the most significant mistakes that evolution ever made.” Yet decades of intense research have failed to discover the key function of sleep. But now, thanks to revolutionary new technology, innovative animal research and extraordinary advances in genetics, all that’s about to change. Join Dr. Jennifer Gardy as she goes on an extraordinary odyssey from a city that never sleeps to an isolation chamber in the Colorado Rockies, from one of the most unique research centres in the world to the world of dreams. Her goal is simple: Discover why we sleep
Like many, Michael Mosley wants to get fitter and healthier but can't face hours on the treadmill or trips to the gym. Help may be at hand. He uncovers the surprising new research which suggests many of us could benefit from just three minutes of high intensity exercise a week. He discovers the hidden power of simple activities like walking and fidgeting, and finds out why some of us don't respond to exercise at all. Using himself as a guinea pig, Michael uncovers the revealing new research about exercise, that has the power to make us all live longer and healthier lives.
An English breakfast, bangers and mash, a bacon butty, and the traditional Sunday roast: dishes synonymous with the great British cuisine. But when the World Health Organisation (WHO) recently said that eating processed meat can cause bowel cancer, and red meat probably causes cancer, many people became concerned that their favourite dinners could be harmful to their health. Tonight How Safe is Meat? Examines the evidence behind the WHO’s announcement, and puts the risks of eating meat in context. Reporter Fiona Foster speaks to leading scientists, medical professionals and representatives of the meat industry to find out: do you really need to bin your bacon buttie?
