Stocker l'énergie - Un défi technologique

NASA launches its most ambitious hunt for traces of life on Mars, landing a car-sized rover in a rocky, ancient river delta. The rover will stow samples for possible return to Earth and test technology that may pave the way for human travel to Mars.

In the cobalt mining areas of Katanga in the Democratic Republic of the Congo (DRC), babies are being born with horrific birth defects. Scientists and doctors are finding increasing evidence of environmental pollution from industrial mining which, they believe, may be the cause of a range of malformations from cleft palate to some so serious the baby is stillborn. More than 60% of the world’s reserves of cobalt are in the DRC and this mineral is essential for the production of electric car batteries, which may be the key to reducing carbon emissions and to slowing climate change. In The Cost of Cobalt we meet the doctors treating the children affected and the scientists who are measuring the pollution. Cobalt may be part of the global solution to climate change, but is it right that Congo’s next generation pay the price with their health? Many are hoping that the more the world understands their plight, the more pressure will be put on the industry here to clean up its act.

The Hubble Space Telescope has spent more than 30 years scrutinizing the cosmos in an attempt to unravel the secrets of the Universe and go as close as possible to its origin. But Hubble has also become the superstar of space, offering us magnificent paintings of the Universe.

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

Does infinity exist? Can we experience the Infinite? In an animated film (created by artists from 10 countries) the world's most cutting-edge scientists and mathematicians go in search of the infinite and its mind-bending implications for the universe. Eminent mathematicians, particle physicists and cosmologists dive into infinity and its mind-bending implications for the universe.

David Attenborough and scientist Johan Rockström examine Earth's biodiversity collapse and how this crisis can still be averted.

In 1996, electric cars began to appear on roads all over California. They were quiet and fast, produced no exhaust, and ran without gasoline... Ten years later, these cars were destroyed.

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.

A video cassette that accompanied Play Tech's Mr. Wizard's Science Secrets kit (#1001), produced in 1994, which included 25 props and a booklet used to demonstrate a variety of physics principles.

A visually stunning documentary that follows science-fiction creator Jeffrey Morris as he explores missions to the Moon—both real and imagined—and why they are a key stepping stone to the future of humankind.

Formula 1 driver Charles Leclerc is part of a 48-hour French Air Force training mission aboard the Rafale, France's supersonic fighter jet! The Ferrari driver joined the members of a squadron of the French Air and Space Force, to take part in their preparation. It was an opportunity for Charles Leclerc to put his physical stamina to the test and experience the extreme sensations of a fighter pilot. A unique opportunity for him to draw parallels between the world of Formula 1 and that of the Rafale.

L'autre monde des dinosaures

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?

Open Brain, dans le cerveau des athlètes

At the edge of our solar system supposedly lies an immense planet. Five to ten times the size of the Earth. Several international teams of scientists have been competing in a frantic race to detect it, in uncharted territories, far beyond Neptune. The recent discovery of several dwarf planets, with intriguing trajectories, have put astronomers on the trail of this mysterious planet. Why is this enigmatic planet so difficult to detect? What would a ninth planet teach us about our corner of the universe? Could it help us unlock some of the mysteries of our solar system?

In the first decades of the 20th century, when life was being transformed by scientific innovations, researchers made a thrilling new claim: they could tell whether someone was lying by using a machine. Popularly known as the “lie detector,” the device transformed police work, seized headlines and was extolled in movies, TV and comics as an infallible crime-fighting tool. Husbands and wives tested each other’s fidelity. Corporations routinely tested employees’ honesty and government workers were tested for loyalty and “morals.” But the promise of the polygraph turned dark, and the lie detector too often became an apparatus of fear and intimidation. Written and directed by Rob Rapley and executive produced by Cameo George, The Lie Detector is a tale of good intentions, twisted morals and unintended consequences.

Le Ciel au Moyen-Âge, Histoire d’Astronomie

Close and daily, sometimes comical but often tragic, sleepiness takes an important place in our lives. Suddenly falling asleep, sometimes with their eyes still open, affects more than 10% of the population. The leading cause of fatal accidents on motorways, drowsiness is also prevalent in the world of work. A silent, irrepressible phenomenon... a flaw in a system of performance, speed, reactivity. So what is happening in our brain? Can we control the conditions of sleepiness? By working on sleep and especially on the functioning of wakefulness, researchers are trying to understand the biological and environmental mechanisms that keep humans at the peak of their abilities. After a clear technological improvement, it turns out that man, having become an expert and process controller, finds it very difficult to focus his attention over time.
