The Hunt for the Oldest DNA

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?

The End of Suburbia: Oil Depletion and the Collapse of the American Dream

Since World War II North Americans have invested much of their newfound wealth in suburbia. It has promised a sense of space, affordability, family life and upward mobility. As the population of suburban sprawl has exploded in the past 50 years Suburbia, and all it promises, has become the American Dream. But as we enter the 21st century, serious questions are beginning to emerge...

Alerte en orbite : la menace des débris spatiaux

Today, hundreds of kilometers above our heads, millions of pieces of trash are orbiting randomly at breakneck speed. Scientists are now warning that, if nothing is done, the exploration outside our planet, and communications systems within, will be almost impossible within 30 years. How can we collect the space trash and avoid future disasters?

But Beautiful

In his new film, Erwin Wagenhofer is looking for the good and beautiful in this world.

Islande, la quête des origines

The fascinating landscape formations of Iceland in the North Atlantic bear witness to the beauty and primal power of nature. They were created through the interaction of powerful volcanic, geological and biological processes that have been changing the face of the earth for billions of years. This is what the Earth might have looked like four billion years ago. Iceland is the realm of ice and fire. Nowhere else is there such a high density of volcanoes. The landscapes, which are continually reshaped by eruptions, make the island a natural laboratory full of clues about the formation and development of the earth. The documentary follows a group of scientists through the most active areas of Iceland, along a mountain range that has emerged from the ocean. On the slopes of the volcanoes, in the fog of the fumaroles and on streams and rivers, the three researchers explore how the first forms of life populated the earth's surface and in what evolutionary steps they took over the earth.

L'Incroyable Histoire des tueurs de bactéries

More and more bacteria are becoming insensitive to antibiotics, not least due to excessive drug consumption. According to the EU, this problem could soon become as explosive as the environmental issue - and antibiotic resistance threatens to become one of the main causes of death worldwide. Research must therefore find alternatives - not miracle cures, but permanently effective drugs. There has already been one in the past: One hundred years ago, the French biologist Félix d'Hérelle discovered mysterious "bacteria-eating" viruses, known as bacteriophages or phages for short. He used these to successfully treat bacterial infections before the development of antibiotics, but his method was forgotten again. Is bacteriophage therapy the miracle medicine of the future?

Size Matters

In a search for clues about size, the documentary shows why the sun and planets are so large, why insects have shrunk in the course of evolution and how tall trees can actually grow. Fantastic thought experiments are visualized: animals grow many times their normal size and a man is shrunk to the size of an insect. The results of the unnatural reversal of size ratios have incredible consequences. What are the advantages and disadvantages? "Size matters" is a scientific documentary narrated with fictional scenes. Parallel worlds are created in which size appears in a completely new light, often in a different way than previously known. Modern, astonishing CGI sequences support internationally recognized scientists on a journey to both ends of the size scale and help to understand the world in its dimensions.

Bora Bora, le laboratoire du futur

Bora Bora is the most popular destination in French Polynesia, certainly because of its lagoon, considered the most beautiful lagoon in the world. In this context, the islet could have sunk under concrete and pollution, and the reef could have been irreparably impacted. However, thanks to the will of a handful of inhabitants including the mayor of the island, Bora Bora is today a model of sustainable development, with water treatment technologies that are 15 years ahead of France, programs to rebuild corals and protect wildlife, educational actions and the rehabilitation of Polynesian traditions such as “rahui” and the establishment of a monitoring network using new technologies. All of this makes the island a veritable open-air laboratory that shows the way for all tropical coastal environments around the world.
