Why do we sleep? And what does sleep have to do with memory, trauma, and our emotions? From fruit flies to whales, virtually every animal sleeps. But why? Why do we need to spend nearly a third of our lives in such a defenseless state? Scientists are peering more deeply into the sleeping brain than ever before, discovering just how powerful sleep can be, playing a role in everything from memory retention and emotional regulation to removing waste from our brains. So why are we getting so little of it?

According to recent science the Neanderthals are not the knuckle-dragging apemen of popular imagination. The first part of the film investigates what Neanderthals looked like and how they lived in their Ice Age world. They were faster, smarter, better looking - and much more like us than we ever thought. Our guide is Ella Al-Shamahi, who enlists the skills of Andy Serkis, the master of performance capture, and a group of experts to investigate deeply Neanderthals appearance.
In the second part, Ella explores the fate of the Neanderthals - asking why they became extinct, and discovering how they live on inside of us today. About 2% of the DNA of most people is of Neanderthal origin - and it continues to affect us today. Neanderthals were a people who were supremely well adapted to their environment. But about 40,000 years ago they disappeared. Why?

Nearly a generation after the acclaimed Blue Planet documentary was released, David Attenborough returns to narrate this groundbreaking sequel/reboot.

There is a battle playing out inside your body right now. It started billions of years ago and it is still being fought in every one of us every minute of every day. This is the story of a viral infection - the battle for the cell.
This film reveals the exquisite machinery of the human cell system from within the inner world of the cell itself - from the frenetic membrane surface that acts as a security system for everything passing in and out of the cell, the dynamic highways that transport cargo across the cell and the remarkable turbines that power the whole cellular world to the amazing nucleus housing DNA and the construction of thousands of different proteins all with unique tasks. The virus intends to commandeer this system to one selfish end: to make more viruses. And they will stop at nothing to achieve their goal. Exploring the very latest ideas about the evolution of life on earth and the bio-chemical processes at the heart of every one of us, and revealing a world smaller than it is possible to comprehend, in a story large enough to fill the biggest imaginations.

This is the dramatic global story of the first year of COVID-19, tracing the devastation caused by the spread of the virus across four continents.
