Exploring some of the world's most isolated and iconic tropical islands.

Journey across Madagascar, the oldest island on Earth. Over time, it has given rise to more unique plants and animals, from its lemurs to chameleons, than any other island.

A journey from Borneo's rich coral reefs, through lush jungles to its mountainous heart, revealing why this island is home to a greater variety of life than almost any other.

Exploring Hawaii, a tropical sanctuary for any wildlife that can reach its remote shores. From humpback whales to waterfall-climbing fish, it is home to an extraordinary wealth of wildlife.

The story of quantum entanglement, perhaps the strangest concept in science. Mind-bending concepts and brilliant experiments lead us to a profound new understanding of reality.

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?

From a single spark of life, through millions of generations, animals have become diverse, weird and beautiful. Chris Packham tells the incredible story in astonishing new detail.

How did the elephant get so big? Chris Packham explores the four-billion-year story of how a tiny cell evolved into complex, gentle giants.

How did the ostrich come to lay the biggest egg on earth? Chris Packham explores the way reproduction has shaped life on earth and the surprising evolutionary origins of sex, eggs and birds. It's a four-billion-year journey contained within a shell.

How did the bat get so hungry? Chris Packham explores how the drive to find food has shaped animal life. The origin of bums, guts, jaws and super hearing.

How did the dolphin get so smart? Chris Packham explores the origins of senses, brains and intelligence, in an evolutionary odyssey that ventures from ocean to land and back again.

How did the horse become so fast? Chris Packham sets out on a slithering, swimming, sprinting odyssey that explores the evolutionary beginnings of animal movement and how it reached its peak in one of the most elegant and athletic animals on earth: the horse.

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.
