Documentary series. Dr Iain Stewart reveals the role natural forces have played in the creation of the planet Earth, beginning with volcanoes

Everything around us - from the tiniest insect on Earth to the most distant stars of the cosmos - exists somewhere on a vast scale from cold to hot. In this series, physicist Dr Helen Czerski explores the extraordinary science of temperature.

Dr Helen Czerksi explores the extraordinary science of heat. She reveals how heat is the hidden energy contained within matter, with the power to transform it from one state to another.

The air around us is not just empty space; it is an integral part of the chemistry of life. Plants are made from carbon dioxide, nitrogen nourishes the soil and oxygen gives us the energy we need to keep our hearts pumping and our brains alive. But how did we come to understand what air is made of? How did we come to know that this invisible stuff around us contains anything at all?

Mark Miodownik reveals the amazing stories behind everyday objects of desire and how they are miraculously transformed from raw materials into the very stuff of the modern world.

Professor Mark Miodownik concludes his odyssey of the stuff of modern life. This time he looks at how materials have enabled us to indulge our curiosity about the world around us.

Professor Jim Al-Khalili sets out to discover what the universe might actually look like.

The second part, Nothing, explores science at the very limits of human perception, where we now understand the deepest mysteries of the universe lie. Jim sets out to answer one very simple question - what is nothing?

Engineer Jem Stansfield is used to creating explosions, but in this programme he uncovers the story of how we have learnt to control them and harness their power for our own means.

Dallas Campbell delves in to the Horizon archive to discover how our ideas about dinosaurs have changed over the past 40 years.

In this film, Professor Marcus du Sautoy explores one of the most dramatic scientific announcements for a generation. In clear, simple language he tells the story of the science we thought we knew, how it is being challenged, and why it matters.

Five of the world's top scientists present the revolutionary scientific inventions they believe could stop global warming and prevent worldwide disaster. Ideas include putting a giant glass sunshade in space to deflect a small portion of the sun's rays back into space and the firing ofrockets loaded with tons of sulphur into the stratosphere creating a vast, but very thin sunscreen of sulphur around the earth

In this episode Brian uncovers how the stunning diversity of shapes in the natural world are shadows of the rules that govern the universe. In Spain he shows how an attempt by hundreds of people to build the highest human tower reveals the force that shapes our planet.

Professor Brian Cox follows Earth's epic journey through space. He takes to the air in a top-secret fighter jet to race the spin of the planet and reverse the passage of the day.

In this episode, Professor Brian Cox shows how Earth's basic ingredients, like the pure sulphur mined in the heart of a deadly volcano in Indonesia, have become the building blocks of life. Hidden deep in a cave in the Dominican Republic lies a magical world created by the same property of water that makes it essential to life.

In this final episode Professor Brian Cox travels to Iceland, where the delicate splendour of a moonbow reveals the colours that paint our world, and he visits a volcano to explain why the sun shines.

Professor Brian Cox combines some of the most spectacular sights on Earth with our deepest understanding of the universe to reveal how the planet's beauty is created by just a handful of forces.

Dr Helen Czerski goes on a spectacular journey to the extremes of the temperature scale, where everyday laws of physics break down and a new world of scientific possibility begins.

Liz Bonnin joins a scientific team on an expedition across the Galapagos Islands to carry out important research that will help protect the islands and their inhabitants.

Liz Bonnin joins a scientific team aboard the research vessel the Alucia on an expedition across the Galapagos Island.

On the second leg of this incredible mission, Liz Bonnin and a team of scientific experts set off beneath the waves to explore this spectacular archipelago. It is an exciting opportunity for the team to delve into a world that still largely remains a mystery to science.

In the culmination of this 1,000km scientific expedition aboard the Alucia, Liz Bonnin and the team of scientific experts journey south to visit the oldest islands in the Galapagos to see first-hand the impact that humans have had on this pristine wilderness.

The first programme begins 350 years ago when a small group of friends, colleagues and rivals defied everything that was known about the world at that time.

The philosopher Friedrich Nietzsche was one of the most brilliant and dangerous minds of the 19th century. His uncompromising and often brutal ideas smashed the comfortable presuppositions and assumptions of religion, morality and science.

Following Great Ormond Street Hospital's doctors.

In the Bone Marrow Transplant Unit at Great Ormond Street Hospital, doctors strive to save the lives of children with life-threatening congenital diseases. They must attempt treatments which have very uncertain chances of success and can even threaten the lives of the children they are trying to save.
