A third of the population regularly struggle with our sleep, which rose to one in two during the pandemic - the highest it's ever been. However, as more and more people seek help, an explosion in sleep science is enabling the study of sleep in ways not possible before. What's more, recent breakthroughs are uncovering what's happening in our brains and bodies while we're asleep, getting us closer than ever to understanding the importance of sleep for our health. Michael Mosley shows why cutting our sleep short can be linked to a host of illnesses, including serious diseases like Alzheimer's.
Revealing the very latest science breakthroughs and packed with personal anecdotes, this programme is a useful guide to anyone looking for tips and insights on how to get the benefits from learning how to sleep well.

D-Day: As It Happens D-Day: As It Happens tells the story of this pivotal event in 20th-century history in a completely new way. Using newly-analysed archive footage, viewers can track the progress of seven people who were there on the day, each of them a real participant in the 1944 invasion. And they can do so moment by moment in real time, encountering the twists and turns of the fighting at the same time as the D-Day seven did, and learning their fate as the action unfolds in parallel with the present, Narrated by Peter Snow, with Channel 4 presenter and former marine Arthur Williams, and experts including former British Army officer Colonel Tim Collins and front-line journalist Lorna Ward. The first programme tells the back stories of the real people that the event is following in real time and sets out their missions over the following 24 hours. The D-Day seven include a paratrooper, a midget submariner, a nurse and a military cameraman.

Artificially intelligent machines are taking over. They’re influencing our everyday lives in profound and often invisible ways. They can read handwriting, interpret emotions, play games, and even act as personal assistants. They are in our phones, our cars, our doctors’ offices, our banks, our web searches... the list goes on and is rapidly growing ever longer. But how does today’s A.I. actually work—and is it truly intelligent? And for that matter, what is intelligence?
The world’s brightest computer programmers are trying to build brighter machines by reverse-engineering the brain and by inventing completely new kinds of computers, with exponentially greater speed and processing power. The documentary looks at how far we’ve come and where machines are headed as their software becomes ever more... cerebral. How close are we from a world in which computers take over—from diagnosing cancer to driving our cars to targeting weapons? If we place more and more of our lives under the control of these artificial brains, what are we putting at risk?

Zachary Quinto embarks on a journey to understand how artificial intelligence may already be a threat to humanity. He visits Facebook headquarters where he learns about a failed AI experiment where two chat boxes created a language that only they could understand. Zach also gets a firsthand look at the world's latest technology, including life-like dolls programmed with advanced AI, robots that learn and communicate telepathically, highly intelligent drones of war, and Uber self-driving cars.

Mind reading might sound like pseudoscientific, but its scientific counterpart, thought identification, is very much a real thing. It's based in neuroimaging and machine learning, and what's really cool is that experiments in mind reading aren't just about spying on what someone is thinking. They're about figuring out what thoughts are even made of.
When you think of something, what does that mental picture actually look like? What resolution is it in? How high fidelity is a memory, and how do they change over time? In this episode, we are going to look at how reading people's minds can help us answer these questions.

Horizon uncovers the secret world of our dreams. In a series of cutting-edge experiments and personal stories, we go in search of the science behind this most enduring mystery and ask: where do dreams come from? Do they have meaning? And ultimately, why do we dream? What the film reveals is that much of what we thought we knew no longer stands true. Dreams are not simply wild imaginings but play a significant part in all our lives as they have an impact on our memories, the ability to learn, and our mental health. Most surprisingly, we find nightmares, too, are beneficial and may even explain the survival of our species.
