Three million years ago, camels roamed through Greenland’s endless forests and our ancestors lived in the trees. It all came to an end with the Ice Ages. What died and what survived, as natural selection shaped the evolutionary tree during this epochal shift from hot to cold? Until now, scientists have known less about the natural world before the Ice Age than they did about the age of dinosaurs, which ended 64 million years ago. A new discovery is set to reveal this lost world, species by species. Led by Danish gene-hunter Eske Willerslev, a team of scientists for the first time in history is sequencing DNA from before the Ice Age. The picture that emerges is of a hot planet, when forests blanketed the Arctic and carbon levels matched those in our atmosphere today. Is this a portrait of our own climate future?

James Cameron teams up with NASA scientists to explore the Mid-Ocean Ridge, a submerged chain of mountains that band the Earth and are home to some of the planet's most unique life forms.

The Dangers of the Fly is an educational film made by Ernesto Gunche and Eduardo Martínez de la Pera, also responsible for Gaucho Nobility (1915), the biggest blockbuster of Argentinean silent cinema. De la Pera was a talented photographer, always willing to try new gadgets and techniques. This film experiments with microphotography in the style of Jean Comandon's films for Pathé and it is part of a series which included a film about mosquitoes and paludism and another one about cancer, which are considered lost. Flies were a popular subject of silent films and there are more than a dozen titles featuring them in the teens and early twenties.

By decoding ancient hieroglyphic texts, Jean-François Champollion gave voice to an enigmatic civilization, but behind his legendary feat is a mysterious brother who made it possible. The recent discovery of correspondence between Jean-François Champollion and his brother Jacques-Joseph now allows us to fully understand how a young, self-taught genius was able to make one of the most important discoveries of the 19th century. Without the ingenuity and unfailing support of his older brother, Jean-François would never have succeeded in solving this enigma, which had international repercussions. With animated sequences of their private correspondence, and with the help of archives and expert analysis, this film revisits this unique scientific, human and intellectual adventure to celebrate the bicentenary of the decoding of hieroglyphics.

Most of us think of death as something clear-cut, and that medical science has it neatly figured out. This feature documentary explodes such assumptions through its exploration of a phenomenon that blurs life and death to an unprecedented degree. In what Tibetan Buddhists call tukdam, advanced meditators die in a consciously controlled manner. Though dead according to our biomedical standards, they often stay sitting upright in meditation; remarkably, their bodies remain fresh and lifelike, without signs of decay for days, sometimes weeks after clinical death. Following ground-breaking scientific research into tukdam and taking us into intimate death stories of Tibetan meditators, the film juxtaposes scientific and Tibetan perspectives as it tries to unravel the mystery of tukdam.

Steel giant Thyssen Krupp in Germany and cargo ship operator Maersk in Denmark are investing huge sums of money with public support to convert their huge and dirty energy consumption to ‘green’. Hydrogen plays a central role in this. At the same time, countries in Africa such as Morocco and Namibia are gearing up to become giga-suppliers of the new energy source. But does it all make sense? Why not just produce green steel in Africa? And what's the story behind the blue hydrogen that is supposed to come from Norway via pipeline? The film follows pioneers on breathtaking projects and shows that the energy transition is more complicated than expected and holds many surprises in store.

Coral reefs are believed by many to have the highest biodiversity of any ecosystem on the planet. A lot of the life found here can seem very alien at first, they occupy less than 1 percent of the ocean floor but yet are home to more than 25 percent of all marine life. Warm water reefs typically come to mind when thinking of the Pacific Ocean and the Caribbean Sea, these reefs are very well known but they don’t just occur in warm waters. In this one hour special, we are brought into this alien environment and discover for ourselves a strange, hidden world that is simply abundant with life, ranging from the weird to the wonderful.
