Gaby Roslin and Amir Khan present a program in which they apply the latest science to some of the worst sleepers. They include an extreme snorer, a man who suffers from night terrors, a woman who has restless leg syndrome, and a man with chronic insomnia for 20 years.
The film also shows a sleep deprivation experiment to test for risky behaviour, pain resistance and emotional control. When the subjects reach the final hours of the challenge, the experiment begins to take its toll as the participants' emotions go into overdrive, with one threatening to quit altogether.

It's known as the Alamo of the ancient world, the story of a band of Jewish rebels and their final stand against the Roman Army. The siege of Masada, recorded nearly 2,000 years ago by Jewish military leader Flavius Josephus, is more than a tale of resistance against impossible odds. It's part of the founding narrative of Israel. But how much of it is true?
We take a look at the events that inspired the CBS television miniseries 'The Dovekeepers' and go to the site of the mountain fortress itself, uncovering new truths about this epic conflict.

Explore how Artificial Intelligence will change your job as new research shows how much of what you do could be done by robots. From truckers to lawyers & doctors, we bring affected workers face to face with AI experts. How can we prepare for the coming changes to the world economy? We are on the precipice of another technological transformation. The last industrial revolution turned society upside down. It ultimately delivered greater prosperity and many more jobs, as well as the eight hour day and weekends. But the transition was at times shocking and violent.
The question is, can we do better this time? We don't realize that the future is not inevitable. The future is the result of the decisions we make today. These technologies are morally neutral, they can be used for good or for bad. There's immense good things they can do, they can eliminate many disease, they can help eliminate poverty, they can tackle climate change. Equally, the technology can be used for lots of bad. It can be used to increase inequality,it can be used to transform warfare. It can be used to make our lives much worse. We get to make those choices.

At an extraordinary moment in the history of one of the world’s oldest and most controversial drugs, Dr Javid Abdelmoneim investigates the very latest medical and scientific research into the effects of cannabis on the brain and the body, to find out whether it will help or harm patients.
Javid meets the young epilepsy patient responsible for changing the law around medicinal cannabis in the UK and sees the remarkable effects it has on his condition. He visits a medicinal cannabis farm in Denmark to learn how a company known for growing the recreational drug are now producing medicinal cannabis to be exported all over Europe. He travels to Israel, to find out why they have been using cannabis as a medicine for over 20 years and meets the scientists studying the safety and effectiveness of cannabis in treating pain. And he meets the so-called godfather of cannabis, who at 88 years old is still an active research scientist and considered the world’s leading cannabis expert.

Michael Wood embarks on a great historical adventure, exploring the stories, people and landscapes that have helped create China's distinctive character and genius over four thousand years. Is the history of the world's newest superpower, from its ancient past to the present day.
Starting in Wuxi, Michael joins the Qin family reunion, when 300 relatives gather to worship their ancestors on Tomb Sweeping Day. 'Like the nation, the family has been through so much,' one says. 'Now everyone wants to know - what are our roots?'
Looking for the origins of the Chinese state, he visits the excavations at Erlitou and sees an exquisite turquoise dragon sceptre from 2000 BC. China's first writing is found on 'oracle bones' dug up from the Shang royal tombs at Anyang in the 1920s. At the Beijing Planetarium, Michael travels back in time as astronomers plot the planetary conjunction that the ancients believed foretold the overthrow of the Shang Dynasty. Next, the Age of Philosophers and Confucius, whose book Analects has had greater influence worldwide than even the Bible, according to some. In Xi'an, we hear how the First Emperor united China and created the authoritarian Qin state that gave us the word China. Finally, Michael returns to the temple fair in Henan for a dramatic night ceremony to give thanks to the ancestors. China, Michael concludes, is rising again, not just because of its economic strength, but because of the incredible solidarity of the Han Chinese view of their own civilisation, their sense of family and, of course, the presence of the ancestors.

The Spirit Molecule investigates dimethyltryptamine (DMT), a naturally occurring psychoactive compound, which exists in humans, and potentially every living organism. Utilizing Dr. Rick Strassman's government-sanctioned, human DMT research as the documentary's backbone, the study's potential impact and its inconceivable revelations emerge. A closer examination of DMT's effects through two traditionally opposed concepts, science and spirituality, The Spirit Molecule unravels the connections between cutting-edge neuroscience, quantum mechanics and human spirituality.
The Spirit Molecule, a simple molecule with enormous implications. The subtle combination of science, spirituality, and philosophy results in an abundance of incredible ideas and theories that could alter the way we understand the nature of reality and our relationship to it.
