NOVA: Mysteries of Sleep Like virtually every other animal, humans need sleep to survive. But why? What do we gain from spending nearly a third of our lives in such a defenseless state? And what's at stake if we sleep poorly? The functions of sleep have long been something of a mystery. But now scientists are peering deep into the brain to see what happens while we snooze. One study reveals that well-timed bursts of pink noise can nudge a person's brain waves, extending periods of slow-wave, or deep, sleep. And toddlers learning new words show that taking even a short nap after learning something new can help the information stick. And when it comes to sleeping poorly, it may turn out that having interrupted sleep can be just as harmful as missing sleep altogether. As scientists come to understand the powerful role that sleep -- or lack of it -- plays in everything from memory to trauma to emotion regulation, one thing is clear: This biological function is as crucial as it is complex.

　　Two high level scuba-divers and long-time friends, Don and Dave, broke a world record for depth in the Boesmansgat cave in South Africa. It would take them 15 minutes to reach the bottom, but 12 hours to surface. Having reached the bottom, against all odds, they find a body. They decide to come back and retrieve it. They call the parents, enrol 8 fellow divers, and hire a cameraman to document the dive. The camera will follow them throughout the preparation and the dive, including to the bottom of the cave. Little did they know that on that historic dive, Dave would not be coming back. In this time of over-performance driven by self-promotion and self-filming comes Boesmansgat, a story of loss and mourning where egoism and altruism, hubris and self-control, risk-taking and spirituality all go hand in hand. A cascade of choices and tense paradoxes that lead to a tragedy long foreseen, yet impossible to prevent. Written by AADP
