In China's Valley of the Kings, there stands a tall, carved stone. It honors the resting place of a woman named Wu Zetian, who rose from concubine to become China's only female emperor. For more than a millennia, history claimed she killed her own children, held power through a ruthless rule of terror, and brought China to the edge of ruin. But are any of these claims true? Join the investigation as we revisit old evidence and reveal new truths, using artifacts and forensic tools to tell the true story of China's Emperor of Evil.

Ascension Island, a remote Mid-Atlantic outpost famous for its big game fishing, is under siege. Tiger sharks, hammerheads, even great whites, lured here every year by the bountiful reefs, are displaying aggressive behavior, culminating in the island's first shark attacks in its history. Join us as we dive into the mystery behind the altered behavior of these hungry predators, and explore whether efforts to bring this delicate ecosystem back into balance is a case of too little, too late.

Even 2,000 years after his death, General Hannibal's battle strategies are still studied today. But of all his military feats, perhaps his greatest was leading his massive Carthaginian army of men and three-dozen elephants across the Alps and into the heartland of Rome in 218 B.C. Until now, the route they took has been a matter of dispute, but thanks to modern-day technology, geomorphologist Bill Mahaney and microbiologist Chris Allen believe they've accurately traced this ancient journey.

It lasted only one day on a small piece of land, but the impact the Battle of Waterloo had on history is massive and far-reaching. This is the definitive account of the fight that ended Napoleon's rule as emperor and altered the destinies of France, Europe, and the world. Based on testimonies of those involved, we reveal the tactical decisions and human dramas that transpired on both sides of the battle to give you an unprecedented look of one of history's most epic conflicts.

Herman Melville's epic ocean adventure "Moby Dick" is an American masterpiece. But was this stirring tale of violence and revenge simply an allegory, or were there real giants of the deep deliberately attacking whaling ships? With the help of centuries old witness accounts and modern day science, we explain how the legend of the great white whale came to be. Then we determine if the multiple sperm whale assaults on ships in the 19th century were indeed premeditated and coordinated.

China, as we know it today, would not exist without the Han Dynasty. About two millenniums ago, its emperors ruled for over 400 years, and yet, few visible remains of this period exist above ground. Underground, however, it's a different story. Join a team of archaeologists as they enter the royal tombs of three emperors spanning the reign of the Han Dynasty. By excavating these sites, they hope to further our knowledge of their wealth, their beliefs, their quest for immortality, and how their culture and philosophy shaped modern China.

Smithsonian Institution scientists race against time to save endangered frogs from a deadly fungus that is ravaging amphibians worldwide.

During the rainy season in Africa, a herd of buffalo can create thousands of pounds of waste in a day, which would be an environmental disaster if not for the dung beetle. These extraordinary insects depend on waste to survive. They eat it, attract mates with it, and raise families in it. Although dung beetles are critical to the ecosystem, they don't have it easy. Every day, they must avoid being trampled, evade predators like bullfrogs, honey badgers, and rock monitor lizards, and rival dung beetle families desperate for the same fecal prize.

South African extreme fisherman Andy Coetzee embarks on an epic series of adventures to reel in some of the world's most elusive and iconic fish species.
