Two thousand years ago, it was a flourishing city in the middle of what is now a Syrian desert. At the crossroads of trade routes, Palmyra attracted caravanners from Mesopotamia, India and China. In what remains of its ruins, rediscovered by Europeans in the 17th century, its numerous necropolises bear witness to a prosperous past. Carved in limestone in the first centuries of our era, the faces of the representatives - men, women and children - of its greatest families adorn the walls of its tombs. Since 2012, Danish archaeologist Rubina Raja has been leading a long-term project to find, document and retrace the family trees and daily life of these Palmyrenians.

This documentary outlines the unique properties and latest studies of "Physarum Polycephalum", also known as Blob.

An account of the last two centuries of the Anthropocene, the Age of Man. How human beings have progressed so much in such a short time through war and the selfish interests of a few, belligerent politicians and captains of industry, damaging the welfare of the majority of mankind, impoverishing the weakest, greedily devouring the limited resources of the Earth.

Based on the latest technological and scientific advances, this documentary explores the palace's architectural past to resurrect Louis XIV's vanished Versailles. Versailles was an ongoing building site at the time of Louis XIV and continued to be transformed by its successive occupants later on. The Versailles we know today only vaguely resembles the Versailles of the Sun King. Most of its original features and apartments no longer exist. Thanks to the digitisation of thousands of plans, a team of scientists takes us back in time to explore this forgotten past in a new way, through a large-scale reconstruction project to bring back the Versailles of Louis XIV as he designed it, according to his requirements and dreams.

Gombessa Expedition 4 Laurent Ballesta went to observe a gathering of thousands of groupers during the full moon of June 2014 (Le mystère mérou) in the southern pass of the Polynesian atoll of Fakarava, where he discovered a pack of over seven hundred grey sharks. How can this unprecedented density be explained? Could it be that social behaviors govern this wild horde? During three years of preparation, he and the other divers on his international scientific team tamed their fear by abandoning the defensive reflexes that provoke shark aggression, with the aim of slipping into the heart of the raging pack to study and film it from the inside. Sharks fitted with microchips, receiving antennas, hydrophones, an ark of 32 synchronized cameras...: a whole technological arsenal is mobilized for the project. As the groupers approach for their annual spawning, what battle plan will the sharks deploy?

Over the centuries, Mont Saint-Michel, an extraordinary island located in the delta of the Couesnon River, in Normandy, France, a place floating between the sea and the sky, has been a sanctuary, an abbey, a fortress and a prison. But how was this architectural wonder built?

Gombessa Expedition 3 Protected by an international treaty Antarctica has been spared the effects of hunting and fishing. But signs in ice’s cyclical patterns and its biodiversity have become worrying. Connected to the planet’s global ecosystem via atmospheric circulation and ocean currents, this white haven is suffering the effects of human activities. To document and explain what is unfolding in Antarctica, photographer, diver, and marine biologist Laurent Ballesta and photographer of extreme environments Vincent Munier will be blending their artistic perspectives of a rapidly changing continent. Laurent will tackle technical and human prowess below the ice to bear witness to its remarkable underwater life. His photographs will advance knowledge on Antarctica’s unique and little-known biodiversity. On land, his eye riveted to the lens of his camera, Vincent captures snapshots of life in an Emperor Penguin colony.

Chambord, the most impressive castle in the Loire Valley, in France, a truly Renaissance treasure, has always been an enigma to generations of historians. Why did King Francis I (1494-1547), who commissioned it, embark on this epic project in the heart of the marshlands in 1519? What significance did he want the castle to have? What role did his friend, Italian genius Leonardo Da Vinci (1452-1519) play? Was he the architect or who was?

Gombessa Expedition 1 To dive for the Coelacanth is to go back in time. In 1938, when it was known only as a fossil, a Coelacanth was discovered in South Africa in a fisherman's net. This species bears witness to an evolutionary bifurcation 380 million years ago, and bears the marks of a great event: the day the fish left the ocean for the open air. Does it hold the secret to the transition to walking on land? In 2010, a marine biologist and outstanding diver, Laurent Ballesta, took the first photographs of the Coelacanth in its ecosystem. In April 2013, divers and researchers set down their equipment at the Sodwana base camp in South Africa, in the club founded by Peter Timm (who died in 2014). Six weeks of extreme diving at depths of over 120 meters, in an attempt to film the Coelacanth with a double-headed camera, collect its DNA and tag a subject with a satellite-linked beacon...

Dark matter fills the cosmos, and yet its identity is still unknown. For the first time, a film portrays the wild scientific quest find out what it is. This breath-taking thriller leads us to the dawn of a scientific and metaphysical revolution, akin to Copernic's or Galileo's. It could totally change the way we perceive our world.

From her birth in Warsaw to her entry into the Pantheon, Marie Curie's work and career is a myth. Honored throughout the world and embodying a model of excellence, its history and life remain unknown in France. An intimate portrait of an exceptional scientist, Nobel Prize in Chemistry, 100 years ago.
