The Ruaha National Park in the south of Tanzania used to be a true paradise for wildlife gathered around the rich Ruaha river. Today however, its sparkling waters are nothing more than a remote dream. Scorching heat and severe drought have dried up the riverbed, leaving animals wandering around, suffering from dehydration. A life-or-death quest for water has begun and the bewildered animals have no choice but to follow the dry riverbed upstream hoping to find water. Witness to this tragedy, a pride of hungry and thirsty lionesses and their cubs overlook the last pockets of water. Although it is dangerous for the young cubs to travel, the females have no choice but to follow the herds of herbivores in their migration. Days go by as the leaden sun scorches the savanna and the winds blow away the few hopes of rain. Will the lionesses and the other animals find water in time to save themselves?

The real story behind the Somali Pirate capture of the Maersk Alabama - and the kill shots that saved the life of Captain Richard Phillips.

200 million years PREHISTORIC NEW YORK was a region that was a semi-tropical landscape rattled by earthquakes and scarred by lava flows. It was home to a bizarre array of amphibians and reptiles, including the dinosaur Coelophysis, a meat-eating, ostrich-like creature. Mastodons roamed the streets of what is now Manhattan. Scientists believe the honey locust trees that now line Fifth Avenue near Rockefeller Center evolved their thorns to protect them from munching by these mastodons.

One of the holiest relics in Christianity, the Turin shroud is believed to have swathed the body of Christ after his death. The image of a bloodied, crucified man burned into the fabric of the cloth was first revealed in 1898 when it was captured in a photographic negative. Subsequent tests in 1988 ultimately dated the shroud to between 1260­1390AD, apparently confirming its status as a medieval forgery. According to Clive Prince and author Lynn Picknett, that forger was none other than Leonardo Da Vinci. A master artist, scientist and anatomist, Da Vinci was the only person with the talents to undertake such a project. Yet scientists have been unable to explain how the image was created. Over 50 attempts to duplicate the relic have failed. New research using Da Vinci’s other works for comparison has drawn some fascinating conclusions...

Bees are vanishing. In 1950, there were 500,000 beekeepers in the U.S. Today there are less than 1,600. Examining the enormity of this loss, Jeremy Simmons' documentary The Last Beekeeper follows the lives of three commercial beekeepers (from South carolina, Montana, and Washington) over the course of a year as they struggle with Colony Collapse Disorder. When they take their bees to California's enormous annual almond pollination (an event so large it requires nearly all the bees in the US), it becomes painfully and poignantly clear the bind they are in. "If all the bees die, what do you have to live for?" asks one of the beekeepers. It's a question for all of us. The cause of Colony Collapse Disorder remains unknown and if honeybees continue to decline at the same rate, they will cease to exist in the U.S. by 2035. Jeremy Simmons' buzz-worthy documentary The Last Beekeeper, a World of Wonder film produced by Fenton Bailey and Randy Barbato. Emmy Award winner for "Outstanding Nature Programming" 2010.

The beautiful, mysterious world of rain is visualized using the latest filming technology. Ultra-high speed cameras capture breathtaking images in Odaigahara, the rainiest area in Japan that receives an annual rainfall of 5,000 millimeters. On the ground form lakes that only appear after summer heavy rains, allowing rare frogs to thrive. In winter, a unique natural phenomenon called Glazed Frost takes place if rain falls unfrozen and the air temperature is below zero. Through poetic cinematography, we discover just how rain enriches the natural beauty in Japan, a country unusually blessed with rain.

Older than Lucy, "Ardi" reveals startling new details about the evolution of the hominid family tree. Following the publication in the journal Science on the find and study of a 4.4 million-year-old female partial skeleton nicknamed "Ardi," Discovery Channel will present a world premiere special. The two-hour groundbreaking special documents the sustained, intensive investigation leading up to the landmark publication of the Ardipithecus ramidus fossils. The scientific investigation that began in the Ethiopian desert 17 years ago opens a new chapter on human evolution, revealing the first evolutionary steps our ancestors took after we diverged from a common ancestor we once shared with living chimpanzees. "Ardi's" centrepiece skeleton, the other hominids she lived with, and the rocks, soils, plants and animals that made up her world were analyzed in laboratories around the globe. The scientists have now published their findings in the prestigious journal Science. "Ardi" is now the oldest skeleton from our (hominid) branch of the primate family tree. These Ethiopian discoveries reveal an early grade of human evolution in Africa that pre-dated the famous Australopithecus nicknamed "Lucy." Ardipithecus was a woodland creature with a small brain, long arms and short legs. The pelvis and feet show a primitive form of two-legged walking on the ground, but Ardipithecus was also a capable tree climber, with long fingers and big toes that allowed its feet to grasp like those of an ape. The discoveries answer questions about how hominids became bipedal. This landmark Discovery Channel special reveals the scientific analysis undertaken by an international team of 47 scientists as they painstakingly piece together the hominid bones and link the evidence of thousands of other animals and plant fossils. The international research team weighed in on the scope of the project and its findings: "These are the results of a scientific mission to our deep African past," s

The identity of Jack the Ripper has remained an unsolved mystery for over a century. Now historian Mei Trow presents a new theory on the unparalleled reign of terror in which at least five women were killed in London’s East End in 1888. Based on two years of exhaustive research, and using modern psychological and geographical profiling techniques, Trow identifies Robert Mann, a Whitechapel mortuary assistant, as the Ripper. Mann was mentioned during the original investigation but has never been put forward as a possible suspect – until now. As Trow pieces together the evidence linking Mann with the Ripper murders, he also makes the case for two additional Ripper victims.

Hidden away in a Sydney vault is a young, pickled pup. For almost 140 years, it's remained locked in its glassy tomb. But this is no ordinary pup. In fact, it's not a pup at all. It's a fetus of an animal more closely related to an Australian kangaroo. It was a marsupial which looked like a dog had stripes like a tiger, yet carried its young in a pouch. How the Tasmanian tiger, or thylacine, came to be extinct is a tragedy, and how it might live again is the pursuit of a scientific miracle. Is it possible or wishful thinking? Herein find the story of one man's obsession and his quest to reverse extinction.

“Did the Mob Kill JFK?” relies primarily on the testimony of author Lamar Waldron and a jailhouse informant who claims that mobster Carlos Marcello boasted that organized crime had orchestrated President Kennedy’s murder. The reason: Because the CIA had been working with the mob to try and assassinate Fidel Castro, with the mob participating in the hopes of getting their casinos in Cuba reopened.

The Iroquois Confederacy's system of democracy begins with a legend. In the distant past, five nations were at war with one another. With the help of the warrior Hiawatha -- also called Ayonwatha -- a leader known as the Peacemaker united all five: the Onondaga, Oneida, Mohawk, Seneca and Cayuga. (Today, there are six nations -- the Tuscarora became part of the confederacy around 1720.) Central to the Peacemaker's plan was the creation of a body of leaders entrusted to govern the nations as a whole while preserving the rights of each tribe.
