Leonardo da Vinci is not just the most famous and most admired of all painters - he is an icon, a superstar. Yet, the man himself remains elusive. Accounts during his lifetime describe a man too handsome, too strong, too perfect to be accurate. But in 2009, the chance discovery in the South of Italy of an ancient portrait with strangely familiar features takes the art world by storm. Could this be an unknown self-portrait by Leonardo da Vinci? Controversy erupts among the experts. The implications of such a discovery have far-reaching consequences for our understanding of the work of this great Renaissance master.

Thanks to new excavations in Mauritius and Madagascar, as well as archival and museum research in France, Spain, England and Canada, a group of international scholars paint a new portrait of the world of piracy in the Indian Ocean.

The correlation between social class and school performance is a major issue across the world. This miniseries is an attempt to go beyond ideological approaches of the problem. It is a pragmatic, scientific, and international exploration of education techniques. Two thirds of students will hold jobs that have not been invented yet and 47% of current jobs are expected to be replaced by machines.

In 1609, Henry IV sent Inquisition judge Pierre de Lancre to the French Basque Country to investigate witchcraft. In the trials, 80 people were sentenced to death at the stake. Between the 15th and 17th centuries, a total of between 40,000 and 60,000 people fell victim to such waves of persecution in Europe. How can this phenomenon be explained?

In 1923, the young French writer Raymond Radiguet (1903-23) published The Devil in the Flesh, a novel that caused a great scandal by telling the story of the love affair between a married woman and a teenager in the middle of World War I.

More than 2.000 years ago, Narbonne in today's Département Aude was the capital of a huge Roman province in Southern Gaul - Gallia Narbonensis. It was the second most important Roman port in the western Mediterranean and the town was one of the most important commercial hubs between the colonies and the Roman Empire, thus the town could boast a size rivaling that of the city that had established it: Rome itself. Paradoxically, the town that distinguished itself for its impressive architecture, today shows no more signs of it: neither temples, arenas, nor theaters. Far less significant Roman towns like Nîmes or Arles are full of ancient sites. Narbonne today is a tranquil town in Occitania

French astronaut Thomas Pesquet recently returned from his expedition to the ISS space station - a veritable laboratory of the future where researchers from all over the world work together. During scientific experiments in space, he investigated how long-term missions, such as to Mars, could become possible.

While our nights have never been shorter, an enlightening round-up of scientific discoveries around sleep disorders.

September 3rd, 1939. Britain and France declare war on Nazi Germany, only two days after the Wehrmacht invades Poland. This day, the sad date when the fate of the world changed forever, the Phoney War began: eight months of uncertainty, preparations, evacuations and skirmishes.

In autumn 2016, demonstrations sprang up all over Europe against the CETA free-trade agreement between the European Union and Canada. The reason? An obscure clause which allows multinationals to sue nation states if they feel their profits may be damaged by government decisions. An investigation into the hidden world of international arbitration.

Long massacred by whaling ships, sperm whales were almost driven to extinction. Saved when whale hunting ceased in the 1980s, the largest predators on the planet had, until then, always been studied from the surface, allowing their life beneath the seas to remain a mystery. For the first time, a team of scientific divers has literally become immersed in the day to day life of a clan.

Faced with the relentless and unstoppable advance of the Soviet Red Army, from the spring of 1944 until the capitulation of the Third Reich in May 1945, the Nazis evacuated the labor, concentration and extermination camps, factories of pain and death which, during years of nightmare, they had established in the occupied eastern territories. Forced to travel enormous distances, thousands of people died along the way from hunger, thirst and exhaustion.

Why do 600 inhabitants of the small southern Spanish town of Coria del Río bear the surname "Japón"? It is the legacy of an unusual expedition that took place 400 years ago: In October 1613, the samurai Hasekura Tsunenaga boarded the galleon "San Juan Bautista" on behalf of the ruler Date Masamune in Sendai, Japan. In addition to merchants, warriors and Spanish sailors, the Spanish Franciscan monk Luis Sotelo, who spoke fluent Japanese, also embarked. The legation wanted to obtain permission from the Spanish King Philip III and Pope Paul V to open a new sea route to India alongside the spice route; in return, Christian missionaries were to be sent to Japan. When he set off, Hasekura Tsunenaga had no idea that the journey would take seven years. Who was this Japanese samurai? What is known about his motives and what is known about the actual background to the expedition?

160 km southwest of Reunion Island, just a few dozen metres beneath the surface of the Indian Ocean, lies the peak of an underwater volcanic structure known as Mont La Pérouse. The base of this enigmatic geological formation lies 5000 meters below sea level, with a size comparable to that of Mont Blanc. Permanent currents and strong winds characterise this site in the open seas, culminating in complex diving conditions under which Laurent Ballesta, together with his Gombessa diving team and local researchers had to navigate in order to conduct the study in depth. Further techniques such as observation and photographic inventory, biological and geological sampling, and the use of cameras and sonars were employed in this challenging expedition.

This extraordinary series is a sweeping account of the rise of Earth’s continents. They are the product of a grand waltz of plate tectonics and the continual evolution of Earth’s crust. As landmasses assemble and separate, they fuel volcanoes and spark earthquakes, building mountains and tearing valleys. We see the Earth, eons in the making, through the eyes of geologists and other scientists.
