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.

The Battle of Little Bighorn lasted nearly 24 hours on June 25, 1876, but the stage had been set decades earlier as settlers, prospectors, and business people began encroaching on Native Americans' sacred land. From the Lakota Sioux facing broken treaties to the attacks that ultimately led up to Bighorn, follow these events unfold. Then, see how this pivotal moment in history marked the beginning of the end of freedom on the Great Plains, the birth of an American cliche, and an ongoing fight for identity against the tyranny of progress.

Almost everything we know today about the beautiful giant ringed planet comes from Cassini, the NASA mission that launched in 1997 and arrived at Saturn in 2004. Since then, the space probe has been beaming home miraculous images and scientific data, revealing countless wonders about the planet, its rings and 62 moons - including some that could harbor life. When the mission approached its final days, it attempted one last set of daring maneuvers - diving between the innermost ring and the top of Saturn's atmosphere.
Aiming to skim less than 2000 miles above the cloud tops, no spacecraft has ever gone so close to Saturn, and hopes were high for incredible observations that could solve major mysteries about the planet's core. But such a daring maneuver comes with many risks and is no slam dunk. In fact, slamming into rocks in the rings is a real possibility. Join NASA engineers for the tense and triumphant moments as they find out if their bold re-programming has worked, and discover the wonders that Cassini has revealed over the years.

The series is a thorough examination of the infamous UFO cult through the eyes of its former members and loved ones. What started in 1975 with the disappearance of 20 people from a small town in Oregon, ended in 1997 with the largest suicide on US soil and changed the face of modern new age religion forever.
In the first episode, Bonnie Nettles and Marshall Applewhite begin to recruit individuals interested in end-of-the-world Christianity, new age religion, and UFOs - but the disappearance of new members soon drives media attention and family concerns.

Could time travel ever be science fact? Time itself may be something you can bend and stretch. Trying to understand if time travel can be possible teach us a lot about the universe. It forces us to take on some of the toughest unanswered questions in all of physics and will ultimately probably lead to deeper understanding of the very nature of the cosmos.

Using cutting-edge research, a dedicated team of archaeologists has compiled the evidence to fill in a 400-year gap in man's knowledge of the bluestones of Stonehenge. By combining innovative 3D scanning techniques, traditional field archaeology and novel laboratory analysis, the team has discovered where the stones were quarried and where they first stood.
Professor Alice Roberts shows how the team made its discoveries and joins Professor Mike Parker Pearson to piece together the final parts of the puzzle, solving one of the toughest challenges ever faced by archaeologists.
