Science turns superhero as it battles to save the planet and preserve the human race.

The experts unearth the amazing breakthroughs that are transforming the resilience and strength of the human body.

Four British astronomers celebrate 50 years of work and friendship by going on a road trip to revisit some of the world's greatest observatories.

In the second of a two-part documentary, David Attenborough explores how much climate change is altering our planet, suggesting ways we can help.

David Attenborough asks three key questions: how and why did Darwin come up with his theory of evolution? Why do we think he was right? And why is it more important now than ever before?

Series in which Jim Al-Khalili traces the story of how the elements, the building blocks that make up our entire world, were discovered and mapped

Series in which Jim Al-Khalili traces the story of how the elements, the building blocks that make up our entire world, were discovered and mapped.He follows in the footsteps of the pioneers who cracked their secrets and created a new science, propelling us into the modern age.

In part two, Professor Al-Khalili looks at the 19th century chemists who struggled to impose an order on the apparently random world of the elements. From working out how many there were to discovering their unique relationships with each other, the early scientists\' bid to decode the hidden order of the elements was driven by false starts and bitter disputes. But ultimately the quest would lead to one of chemistry\'s most beautiful intellectual creations - the periodic table.

In the final part, Professor Al-Khalili uncovers tales of success and heartache in the story of chemists' battle to control and combine the elements, and build our modern world. He reveals the dramatic breakthroughs which harnessed their might to release almost unimaginable power, and he journeys to the centre of modern day alchemy, where scientists are attempting to command the extreme forces of nature and create brand new elements.

Through compelling testimony from 7-10 year-old survivors, this film reveals how the deadly wave and the Fukushima nuclear accident have changed children's lives forever

After one of the hottest years on record, Sir David Attenborough looks at the science of climate change and potential solutions to this global threat.

Today, the topic of climate change is a major part of daily life, yet 40 years ago it was virtually unheard of. Since then, Horizon and the BBC have followed scientists as they have tried to unpick how the climate works and whether it is changing.

The nation's love affair with the coast will be reawakened for this entertaining and ambitious exploration of the entire UK coastline. Across 13 programmes Coast celebrates the unique character of the UK's coastal communities, exploring a wealth of fascinating human stories through a mixture of expert comment, contemporary storytelling and computer-generated images. This is the coast as never seen before.

The South Wales coast, by the Second Severn Bridge, has the second highest tidal range in the world, at around 14.5 metres (the highest is the Bay of Fundy, located off the northern coast of Maine, USA). It's also home to an extraordinary tidal phenomenon - the Severn Bore.

The coast of North West England covers some classic industrial landscapes and playgrounds, and a dangerous world of shifting sands.

Scotland's west coast has the most jagged and dramatic coastline in Great Britain. It's only 300 miles as the seagull flies, but once you add in the dozens of islands anchored off this rugged coastline it is thousands of miles.

This is a coast of two halves, divided by the broad Humber. We start on the craggy grandeur of the Yorkshire coast and finish by wading through the vast salt marshes and mudflats of the Wash.

Every beach, bay and cliff edge along this stretch of coast has a story to tell of people who struggled with changing sea levels, the perils of flooding, subsidence and erosion. Whole towns have been lost to the sea, houses teeter on cliff tops... the very land is crumbling away.

In this programme we look back at some of the highlights of our journey, exploring the future of our coast and what it'll mean for us as an island nation.

Helen Czerski goes in search of colour. She reveals what it is, what it does, and why colour doesn't exist outside of our perception.In the first episode, Helen seeks out the colours that turned planet Earth multicoloured. This is an HQ version.

The raw, early Earth had plenty of colour, but that was nothing compared with what was going to come next. That canvas was about to be painted with a vast new palette - and the source of those colours was life. Green is the colour of the natural world and yet it's the one colour that plants have evolved not to use.This is an HQ version.

We can't see in ultra violet, but many animals can. Helen explores what the world looks like to the birds and the bees. With the discovery of x-rays we could look inside ourselves in ways that previously had only been possible after death.This is an HQ version.

Hannah Fry leads a nationwide experiment to help plan for the next deadly flu pandemic, which could happen at any time. How many will it kill? What can we do about it?

When Neil Armstrong stepped onto the moon in 1969, America went down in popular history as the winner of the space race. But that history is bunk. The real pioneers of space exploration were the Soviet cosmonauts.

Astronomer Carl Sagan leads us on an engaging guided tour of the universe, bringing such topics as Einstein\\\'s theory of relativity and Darwin\\\'s theory of evolution down to a layman\\\'s level of understanding. The first episode opens with a description of the cosmos and introduces the iconic \\\'Spaceship of the Imagination\\\'
