Auf Messers Schneide - Eine Geschichte der Chirurgie

Discover the evolutionary secrets of some of the world’s most majestic creatures. From voracious crocodiles and acrobatic birds to stupendous whales and majestic elephants, this documentary follows top scientists on a global adventure as they follow clues from the fossil record and change what we thought we knew about the evolution of iconic beasts.

Professor Alice Roberts follows a decade-long historical quest to reveal a hidden secret of the famous bluestones of Stonehenge. Using cutting-edge research, a dedicated team of archaeologists led by Professor Mike Parker Pearson have painstakingly compiled evidence to fill in a 400-year gap in our knowledge of the bluestones, and to show that the original stones of Britain’s most iconic monument had a previous life. Alice joins Mike as they put together the final pieces of the puzzle, not just revealing where the stones came from, how they were moved from Wales to England or even who dragged them all the way, but also solving one of the toughest challenges that archaeologists face.

On the surface it seems Jade has it all, including a successful marketing career, a heart surgeon husband who is admired and respected in the community, and a young daughter they both dote on. However, behind closed doors, her life is far from perfect.

A biographical documentary about the Belgian free-diver Fred Buyle and his art of silent diving.

The Mandrin Cave in the Rhône Valley is a fascinating excavation site. Archaeologist Ludovic Slimak discovered fossils and flints here, proving that Neanderthals inhabited the cave for over 80,000 years. The first Neanderthal in France for half a century was also unearthed in the cave: He was given the name Thorin.

In this DVD, Mr. Riddle shares the results of his much reading and research in the area of Carbon 14 dating, and explains the importance of Carbon 12 in conjunction with C-14. He explains in simple terms the molecular breakdown process. He also discusses other dating methods and the underlying assumptions the methods are based on, the correctness of which are brought into question. Mike is an interesting and dynamic speaker. His visual aids are excellent. Mike Riddle has degrees in mathematics and education. He's a former Marine, national decathlon champion, former technical specialist and manager for Microsoft, and teacher at ICR's graduate school.

What happens when a group of Finns travel to a tiny village in Benin to participate in a vaccination study? By participating, they can aid in the development of a diarrhea vaccine for children in developing countries – and, at the same time, have a different kind of vacation in West Africa. The complicated side of helping people and the clashes between two cultures rise to the forefront of Mia Halme’s delicious documentary film.

Pushing the limits of the human race: that is what runners aspire to when they take to the Olympic 100-meter track every four years. But for Usain Bolt, the record holder for the distance with his explosive 9.58 seconds, to become the fastest sprinter in history, crossing the finish line at some 44 km/h, it took more than a century of technical refinement. From the early days of sprinting to Usain Bolt's records, directors Jean-Christophe Rosé and Benoît Heimermann trace the history of the 100 meters, the flagship event of the Olympic Games, and its champions.

Bacteria, viruses, but also fungi, algae, pollen, and even insects: micro-organisms thrive and circulate constantly in our sky. How can so many living beings find their way into the air and circulate? How do they survive? And what influence do they have on our lives and the living world? Biodiversity, health, climate: it is only recently that scientists have begun to understand how this discreet aerial "plankton" affects our lives and our ecosystem. But despite their many virtues, some of these micro-organisms are now threatened by human activities. With the help of experts and 3D models, this scientific investigation plunges us into the heart of a still mysterious world, and reveals the diversity and fragility of the air we breathe.

In 2001, satellite imagery captured a mysterious “thermal anomaly” on an unexplored volcano at the ends of the Earth. What lies inside could provide new clues to help predict volcanic eruptions around the globe. But the island is so remote with conditions that are so extreme. No one has ever been able to reach the top to investigate what lies inside.. until now.

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.

Twenty years after A Brief History of Time flummoxed the world with its big numbers and black holes, its author, Stephen Hawking, concedes that the "ultimate theory" he'd believed to be imminent - which would conclusively explain the origins of life, the universe and everything - remains frustratingly elusive. Yet despite his failing health and the seeming impossibility of the task, Hawking is still devoted to his work; an extraordinary drive that's captured here in fleeting interview snippets and footage of the scientist sharing a microwave dinner with some fawning PhD students. Though the pop-science tutorials that dapple the first of this two-part biography are winningly perky, Hawking, alas, remains as tricky to fathom as his boggling quantum whatnots

Filmmaker Werner Herzog combs through the film archives of volcanologists Katia and Maurice Krafft to create a film that celebrates their legacy.

Offshore wind farms are a major player in the move away from fossil fuels, especially in the North Sea, and they are increasing in number. But their impact on the environment is not yet clear: We take a look at ongoing research in Europe that is measuring the impact of wind turbines and their harm, or benefit, to biodiversity in our seas.

A team of archaeologists examines an ensemble of finely crafted gold and silver artifacts from a temple in Laos. The expedition takes the researchers from the vault where the treasure is now housed to ancient temples hidden deep in the jungle. The team makes spectacular discoveries at excavation sites scanned from the air...
