The story of how the secret of life has been examined through the prism of the most complex organism known - the human body. It begins with attempts to save the lives of gladiators in Ancient Rome, unfolds with the macabre work and near-perfect drawings of Leonardo in the Renaissance, through the idea of the 'life force' of electricity, to the microscopic world of the cell. It reveals how a moral crisis unleashed by work on the nuclear bomb helped trigger a great breakthrough in biology - understanding the structure and workings of DNA.

A stunning documentary about the escalating global nuclear arms crisis, Countdown to Zero is a fascinating and frightening exploration of the dangers of nuclear weapons, exposing a variety of present day threats and featuring insights from a host of international statesmen and experts. Among the voices are President Jimmy Carter, Mikhail Gorbachev, Pervez Musharraf, Tony Blair, former CIA Operations Officer Valerie Plame Wilson, the Ploughshares Fund’s Joe Cirincione and Stanford political scientist Scott Sagan. traces the history of the atomic bomb from its origins to the present state of global affairs: nine nations possessing nuclear weapons capabilities and others racing to join them, with the world held in a delicate balance that could be shattered by an act of terrorism, failed diplomacy, or a simple accident. It makes a compelling case for worldwide nuclear disarmament, an issue more topical than ever with President Obama and other world leaders working to revive this goal today. Written and directed by Lucy Walker, Countdown to Zero was screened for attendees of this year’s Global Zero International Conference in Paris and the TED Conference in Long Beach, California.

After 400 BC, a new philosophy was born in South east Asia, generated from the ideas of Buddha, a mysterious Prince from India who gained enlightenment while he sat under a large, shapely fig tree. He remains one of the most legendary and influential of all religious progenitors, but what of his actual life? In this biographical documentary, director David Grubin tells the historical tale of Gautama Buddha (563-483 BC), from his initial enlightenment through his death around the age of 80. In the process, Grubin makes an unusual point: that Gautama never once claimed to be God or God's emissary, but instead sought to find a way to bring peace and alleviation from suffering to others in a cruel and often insane world. In telling this story, Grubin combines a number of elements including original animations, testimony by contemporary Buddhists such as the 14th Dalai Lama Tenzin Gyatso, glimpses of sculptures and paintings that help tell Gautama's story, and much more.

In May 2009, NASA astronauts embark on a mission to perform maintenance and repairs to the Hubble Space Telescope. As they go about their tasks, danger and beauty are never far away. The nature of space indicates that even the simplest routine can go fatally awry, while amazing photographs taken by the telescope celebrate the wonder of Earth's celestial surroundings.
An IMAX 3D camera chronicled the effort of 7 astronauts aboard the Space Shuttle Atlantis to repair the Hubble Space Telescope.

There are 200 million insects for each of us. They are the most successful animal group ever. Their key is an armoured covering that takes on almost any shape. Darwin's stag beetle fights in the tree tops with huge curved jaws. The camera flies with millions of monarch butterflies which migrate 2000 miles, navigating by the sun. Super slow motion shows a bombardier beetle firing boiling liquid at enemies through a rotating nozzle. A honey bee army stings a raiding bear into submission. Grass cutter ants march like a Roman army, harvesting grass they cannot actually eat. They cultivate a fungus that breaks the grass down for them. Their giant colony is the closest thing in nature to the complexity of a human city.

The Indian Ocean is the third largest body of water on Earth at more than 6,000 miles wide and covering 13% of the world's surface. It is home to 5,000 species of fish, many of which only exist in the Indian Ocean. But it is also an ocean under threat from global issues such as over-fishing and climate change, which make this an ocean on the edge.
