The fifth programme explores the alliances formed between the animal and plant worlds. Attenborough dives into Australia's Great Barrier Reef and contrasts the nocturnal feeding of coral, on microscopic creatures, with its daytime diet of algae. Some acacias are protected by ants, which will defend their refuge from any predator. Besides accommodation, the guards are rewarded with nectar and, from certain species, protein for their larvae as well. Fungi feed on plants but can also provide essential nutriment to saplings (Mycorrhiza). The connection is never broken throughout a tree's life and a quarter of the sugars and starches produced in its leaves is channelled back to its fungal partners. Meanwhile, fungi that feed on dead wood leave a hollow trunk, which also benefits the tree. Orchids enjoy a similar affiliation. Lichens are the product of a relationship between fungi and a photosynthetic associate, usually algae. They are extremely slow-growing, and a graveyard is the perfect location to discover their exact longevity. Mistletoe is a hemiparasite that obtains its moisture from a host tree, while using own leaves to manufacture food. Its seeds are deposited on another by the mistletoe tyrannulet, following digestion of the fruit. The dodder (Cuscuta) is also parasitic, generally favouring nettles, and siphons its nourishment through periodic 'plugs' along its stem. The rafflesia has no stem or leaves and only emerges from its host in order to bloom — and it produces the largest single flower: one metre across.

Richard Hammond explores the extraordinary wonders of the world of detail hidden in the blink of an eye. It takes our brain around a hundred and fifty milliseconds to process what we see. We're not aware of this time lag going on, but in those few milliseconds, there are extraordinary things happening that completely pass us by. But what if we could break through this speed limit? Bend and stretch time in ways never thought possible. What new marvels would we see? Now, using the latest high-speed cameras, Richard takes us on a journey beyond our eye's limits, letting us see secrets hidden in every element of our planet. A world where thin air can shatter rock. And water can tear through metal. A world where the fastest thing on earth lies right beneath our feet. And where a spectacular celestial display is finally captured, even though many have claimed it doesn't even exist.

There are some who believe that Darwin's theory of evolution has weakened religion. Conor Cunningham argues that nothing could be further from the truth.He travels to the Middle East where he shows that from the very outset, Christianity warned against literal readings of the biblical story of creation. In Britain, he reveals that, at the time, Darwin's theory of evolution was welcomed by the Anglican and Catholic Churches. Instead, he argues that the conflict between Darwin and God was manufactured by American creationists in the 20th century for reasons that had very little to do with science and religion and a great deal to do with politics and morality. Finally, he comes face to face with some of the most eminent evolutionary biologists, geneticists and philosophers of our time to examine whether the very

The key to understanding the universe seems to be understanding its smallest components. But the quantum realm bears little resemblance to the universe we know. Image a particle that can be many places at the same time and communicate changes instantly across vast distances, even to the other side of the Universe. Shrinking down billions of times, into the realm of atoms and sub-atomic particles, takes us into a bizarre world of paradoxes and multiverses. Explore with us quantum physics and the potential applications in computer science.

The documentary chronicles the fall of the Atari Corporation through the lens of one of the biggest mysteries of all time, dubbed 'The Great Video Game Burial of 1983'. As the story goes, the Atari Corporation, faced with an overwhelmingly negative response to 'E.T.', the video game for the Atari 2600, disposed of hundreds of thousands of unsold game cartridges by burying them in the small town of Alamogordo, New Mexico.
