The story of how one Russian internet millionaire is turning to cutting-edge science to try to unlock the secret of living forever. Dmitry Itskov recently brought together some of the world's leading neuroscientists, robot builders and consciousness researchers to try to devise a system that would allow him to escape his biological destiny. Entering Dmitry's seemingly sci-fi world, Horizon investigates the real science inspiring his bold plan to upload the human mind to a computer. There are doubters - like the major neuroscientist who tells us 'it's too stupid, it simply cannot be done'. But as we also meet the Japanese maker of Erica, one of the world's most human-like robots, who tells us the destiny of humans is to become robots to overcome the constraints of time, see how a quadriplegic Californian man is already controlling a robot arm with his thoughts, and explore the groundbreaking work of the scientist behind the world's largest neuroscience project - the $6 billion US Brain Initiative - who tells us the effort to map all the activity of the brain could be a crucial step towards mind uploading, Horizon asks is it really so crazy to think Dmitry Itskov could succeed in his goal of bringing about immortality for all of us within 30 years?
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 World Health Organisation has described stress as 'the health epidemic of the 21st century'. In this programme Fiona Phillips wants to understand why we are experiencing increased amounts of stress in our lives and what actions we can take in order to reduce it. Fiona explores some of the very latest scientific research behind stress and demonstrates a number of techniques and lifestyle changes which are designed to keep our high stress levels in check.

Diseases that were largely eradicated in the United States a generation ago—whooping cough, measles, mumps—are returning, in part because nervous parents are skipping their children’s shots. NOVA's "Vaccines—Calling the Shots" takes viewers around the world to track epidemics, explore the science behind vaccinations, hear from parents wrestling with vaccine-related questions, and shed light on the risks of opting out.
In the United States, it’s estimated that 30 percent of adults and 66 percent of adolescents are regularly sleep-deprived. This isn’t just a minor inconvenience: staying awake can cause serious bodily harm. Claudia Aguirre shows what happens to your body and brain when you skip sleep.
