The discovery of an ancient music score in the Louvre sets researchers on a mission to recreate the music as it was originally heard by the Greeks 2,400 years ago.

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.

In Iraqi Kurdistan, a region that has not yet been explored, a formidable archaeological adventure is taking place where scientific knowledge is the answer to oblivion.

When a huge meteorite crashed into the earth 66 million years ago and caused the disappearance of the dinosaurs, some of the planet’s tiniest species survived the cataclysm, and—against all odds—eventually became some of the greatest giants to ever roam the earth. From the poles of the planet to the belly of the equator, this documentary sheds new light on four giant animals that are still a great mystery to science today: the Titanoboa snake, the Megalodon shark, the giant rhinoceros and the giant sloth.

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?

For the past 20 years, the world has seen an alarming decrease in IQ and a rise of autism and behavioral disorders. This international scientific investigation reveals how chemicals in objects surrounding us affect our brain, and especially those of fetuses.

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.

As most plastic never deteriorates, it simply breaks down into smaller and smaller particles that are invisible to the human eye, what happens to this missing ocean plastic is a mystery. In this investigation, scientists embark in search of the micro-plastics. Small, mostly invisible, toxic, they are home to the new ecosystem: the plastisphere. But where are they? Ingested by organisms? Buried under the ocean floor? Degraded by bacteria? And what is the impact of them entering the food chain?

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?
