The immune system is a powerful army of cells that fights like a T-Rex on speed and sacrifices itself for your survival. Without it you would die in no time. This sounds simple but the reality is complex, beautiful and just awesome. An animation of the immune system.

Modern life would be impossible without plastic – but we have long since lost control over our invention. Why has plastic turned into a problem and what do we know about its dangers? This video is a collaboration with UN Environment and their Clean Seas campaign, If you want to take action to turn the tide on plastics, go to http://www.cleanseas.org and make your pledge.

A hormone is a class of regulatory biochemicals that is produced in all multicellular organisms by glands, and transported by the circulatory system to a distant target organ to coordinate its physiology and behavior. Hormones serve as a major form of communication between different organs and tissues.
This week, we meet a girl whose heart has formed outside her ribcage, a man who can spend nine minutes underwater without taking a breath, a woman who is growing a second skeleton and a paralysed man who is regaining movement thanks to a chip implanted into his brain that can 'read' his brain signals.
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
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.

With a family history of heart problems, presenter Michael Mosley takes a personal interest in these pioneers, who teetered on the scalpel-edge between saviour and executioner.
