Over the centuries, explorers traded tales of a lost civilization amid the dense Amazonian rainforest. Scientists dismissed the legends as exaggerations, believing that the rainforest could not sustain such a huge population -- until now. A new generation of explorers armed with 21st-century technology has uncovered remarkable evidence that could reinvent our understanding of the Amazon and the indigenous peoples who lived there.

Gold's appeal and value span time and cultures, but there is a little-known secret to the story of gold. Most of the gold mined throughout history remains in circulation today -- even the gold closest to your heart may have dark origins. From the Amazon jungle to the markets of Dubai, NGC examines the underbelly of the modern gold trade with a treasure hunter and an illegal miner to expose its volatile history.

In order for the Congo to receive vital supplies, brave men and women known as bush pilots must risk life and limb to transport cargo to this remote region of the world. Landing strips are often little more than pitted dirt roads, local militia is known to fire on them and water buffalo may block the runway, so what drives them to do it? In this episode of Explorer, we'll meet some bush pilots, hear their harrowing accounts and witness firsthand the challenges they face in the Congo.

This National Geographic documentary explores the physical and psychological changes experienced by the human body in the moments before and after death. When does a person really die, and what happens at that precise second when life ends? While the subject both frightens and fascinates, understanding both the science of death and the ways in which our bodies hold it off are key to understanding the complete cycle of human life.

Sharks have thrived in the oceans for over 350 million years, but around 20 million years ago a new species emerged in the fossil records in a form unlike ever seen before... the Hammerhead Shark. Why did this bizarre looking creature evolve was it a need for greater maneuverability, a need for a more advanced sensory system or was it a genetic mistake? And how has the Hammerhead continued to survive? Scientific evidence suggests that Hammerheads seek out distant destinations but what prompts them to travel these great lengths? How do they navigate? Do they possess an internal compass? Do they possess a map? Dr. Pete Klimley is seeking to answer these questions and discover how Hammerheads live and survive across the turbulent seas by mapping their underwater movements. In a world threatened by over fishing and declining populations the Hammerhead Highway may be the key to understanding and ensuring the Hammerheads survival.

Entombed in a glacier in the Alps for more than 5,000 years, the Iceman is the oldest mummy ever discovered. Scientists now know he was murdered in cold blood, but why? In 2007, National Geographic sponsored a series of new CT scans that revealed three potential motives. Was the Iceman assassinated, a victim of clan warfare or part of a ritual murder? Forensic clues surrounding his death continue to illuminate the origins of conflict and violence in the Copper Age.

The world is addicted to oil. But now the easy pockets of oil are gone and the race is on to find new sources. Nowhere is the battle more intense than in Alaska - source of nearly 15% of America's domestic production, and home to the nation's largest wildlife preserve, the Arctic National Wildlife Refuge, where companies are pushing to drill. EXPLORER travels back millions of years to see how oil was created, and looks to the future to ask how far we'll go to find every last barrel and at what cost.
