The film follows four unique divers as they explore shipwrecks in the heart of the Bahamas archipelago in order to discover the unexpected life they harbor.

A plunge into New Zealand's Ultramarathon preparations, a tradition that comes from a Maori legend. 55 year-old Lilac Fley is an athlete and many times winner of the extreme race. A Maori legend dictates the course of the Ultramarathon. It tells the story of a boy who once lived with his tribe on the New Zealand coast. One day his mother asked him to search for some kumaras, or sweet potatoes, for a meal. Instead of digging for them, he decided to steal some from the neighboring tribe. Till this day, runners follow in his footsteps along the coastline - during New Zealand's most famous marathon.

Rick Dirks is one of the best tree climbers in California. He is able to climb 100-meter tall (328-foot) redwood trees with skill and courage and do so at breathtaking speed. He even ties himself to the crown of these giant trees in a sleeping bag for the night. In addition to trimming the trees and installing measuring tools, Rick collects the tree's cones and seeds at dizzying heights – because the redwoods can only continue to survive if they are cultivated. In California, these giant trees are still cut down for timber.

The international scientific community is called on to take sides and provide solid answers. "Surrounded by Waves" explores the methods and motivations behind the most prominent research in the field and clarifies what we currently know, all with a mind to the social context behind the issue. Through an elegant blend of interviews, archives, experiments and 3D animation, the film clearly assesses the estimated risk linked to cell phones while offering a subtle observation of society's growing distrust of its industries and the unprecedented role of science in the debate.

They orbit between us and our Star, the inner worlds; hidden within the sun's glare often only visible at sunrise or sunset. Venus the first and brightest star in the evening sky, and Mercury fleeting across the solar disk. They are half of our solar system's terrestrial planets yet we know so little. As we begin to take a closer look at our companions they are posing more questions than answers.

From the beginnings of our Solar System four and half billion years ago there remains tantalizing clues to its evolution; remnent debris: asteroids and comets. They vary in size from grains of dust to mountain sides, footballs to planetoids. They were the building blocks of the planets and perhaps carry the origins of life itself. Now within our grasp these rocks of ice and dust are ready to give up their secrets.

The European islands are renowned primarily for their hotel resorts. However, we will show you a completely different face of theirs: forests, beaches, coves, mountains, valleys and rivers. Perhaps you will find places that will take your breath away. Why just lie on the beach when there is so much to see? Put on some good hiking shoes, pull your shoelaces tight, and get to know the entire island like the back of your hand.

Westward ho! We settle in Salt Lake City, where we learn about Bringham Young's settlement of the Utah territory and his monument at This is the Place Park. Then we dig in the dirt to find hundreds of perfectly preserved dinosaurs at the Utah Natural History museum. We'll take a look at some US aviation history at the Hill Air force Base museum, and see how life was like for the Utah pioneers at Frontier Homestead State Park.

TTH heads to the great white North…kind of. We visit the world class city of Toronto. There we'll head straight up the Western Hemisphere's tallest structure, the CN Tower. Next we score a look at the Hockey Hall of Fame and see a North American castle at Casa Loma. Finally we see how the British defended their city against the newly formed United States at Fort York.

Built in the early 1800s, Whitby Hall used to be an administrative center and now stands as a public park and arts center. It has never before been investigated, but staff have reported many noises and presences among them.

On the 11th of November, 1918, the First World War drew to an end with a terrible toll… after a conflict unlike anything Humanity had ever seen before. For 4 years and 3 months, soldiers from at least 20 countries were plunged in the hell of trenches… caught under a deluge of bombs.

On 28 May 1940, while the Wehrmacht crushed the allied armies in France, British officials are prepared to deal with Hitler. They even suggest a mediation from Mussolini. Alone against all in the war cabinet, Churchill, by his cleverness and willingness, finally convinced his collaborators to fight.

Seg 1 Visually-Evoked Auditory Response. VEAR or Visually Evoked Auditory response is the type of auditory perception where our brains perceive to hear sounds in response to seeing something. In the case of the jumping pylon illusion, a thud sound is perceived even though there is no sound accompanying the animation. Seg 2 Retinal Fatigue. Retinal fatigue is the term used to describe the condition when the photoreceptors in our eyes become tired or strained due to staring at one color for extend periods of time. The effect causes an afterimage of the complementary color to appear out of nowhere and will be temporarily visible for a few seconds. Seg 3 Müller-Lyer illusion. The Müller-Lyer illusion is an optical illusion where parallel lines of the same length appear longer when perceived with different pointed arrowheads drawn at the ends. Possible explanations suggest that our minds tend to look at overall length rather than just the line's parts or segments when processing the image. Another possible explanation is that our minds tendency to look at angled lines and perceive patterns of depth. Seg 4 Ames Room. The Ames room is a specially constructed room that features a distorted and skewed floor plan. when viewed from one angle, our brain is tricked into thinking that the perspective of the rooms is normal but when a person walks from one end to another the distorted floor angle makes it look as if the person changes size drastically. Seg 5 Synesthesia. Synesthesia is a genetic condition that is present in at least 4% of the human population. People with synesthesia have hyper connected neurons that allow them to perceive a stimuli as interconnected with different senses. An example of which is the ability to see color while hearing sounds.

It's the biggest museum in the world…the museum of artworks stolen over the centuries and never rediscovered. These works haunt the nightmares of their owners, and occupy the days of hundreds of police officers across the world, as well as those of a handful of private agencies; no country or museum of importance can claim to have been spared.

Plastic has become ubiquitous. Impressive, since we'd been living without them for centuries! We have grown dependent on plastics in many ways. The production industry uses it to connect the parts that make machinery: our trillions of toilet bowls need it, let alone wash machines, computers, toothbrushes, pens and traffic lights. Can you imagine that plastic was accidentally invented for the purpose of making billiard balls? Though, its inventor had used something now called guncotton, which led to a rather explosive game of pool. In the end, the first plastic was discovered when someone witnessed how Southeast Asian farmers used the poop of a little beetle, called shellac, to preserve wood. When looking for a substitute, Leo Beakeland created "Bakelite" and that substance turned out to be the first plastic. Nylon followed, the first man-made synthetic plastic, developed by Dupont to replace silk. Nylon isn't that difficult to make yourself, amazingly. During WW2 all nylon production went into the manufacturing of parachutes, leading Dupont and others to stop producing pantyhose. It led to true nylon riots. Plastics were plain out popular. Indeed, the age of plastic had only just begun. But plastic is made with oil and is hard to break down, which calls for a solution. A company in the US is creating a bioplastic grown inside microorganisms. In fact – soon they'll have plants cultivating plastic… plastic grown in the field? Now that is quirky!

The Internet was invented during the cold war and launched in 1969. Yet it wasn't made for the public. In fact, it was developed for the army to communicate quickly and secretly so that no spies could intercept and no bombs could disrupt the sharing of information! It was nothing like we know today. The Internet involved computers exchanging text, on a black field with green letters, and e-mail was only invented 2 years later because the developers needed a reliable tool to communicate. So only in 1972 was this application; electronic mail, introduced. The Internet we know now was actually a second, separate invention, launched over a decade and a half after the Internet was first launched, and was called the 'World Wide Web'. Nobody was paying attention to Tim Berners-Lee and his pet idea, even though he had a radical new way for scientists to share data by linking documents to one another over the Internet! His proposal came back with the words "vague but exciting" written across the cover, so Berners-Lee took his invention to the people: with a website, bringing us the Internet we know today. Yet the Internet is only just out of its baby shoes, and is now being used to drive radical change in music and films, politics and business, changing the very way we see and interact with one another! From the computer screen to mass protests in the street, So what will the future bring us, how will the Web 3.0 change us? A web that can understand human needs?

On the plains of East Africa an epic journey is underway. Millions of wildebeest and thousands of zebras march in an annual, circular migration in search of lush grazing.Two major rivers, the Mara and the Grumeti, intersect their route and force the herds to cross. Crocodiles, the biggest living on earth, wait in these rivers to take advantage of this moving feast. In this ever-changing waterscape successful predators adapt their hunting strategies to suit the shifting environment.On the Grumeti River, DC is the Dominant Croc of a lose gang called the RagTags. When the wildebeest arrive to drink, these Pit Stops, Zone 1, are the crocs' first challenge. It doesn't go well for the RagTags. These smaller, inexperienced crocs don't calculate their launch speed correctly, so opportunities are missed. DC finds a pool where he can work alone. He grabs an impressive male zebra, but the pool's not deep enough to drown it. The zebra fights hard and DC is forced to let it go.Deep Water, Zone 2, is a zone exclusive to the Mara River. Steep banks and fast-flowing water make it a river that favours the crocodiles. Wildebeest plunge off the cliffs straight into the deep channel. To hunt here is easy: Swim, launch and drown.There's no free lunch on the Grumeti. DC waits for the next opportunity. He picks up vibrations in the water that tell him the herds have started to cross. Zone 3, The Shallows, is a dangerous zone for crocodiles. Wildebeest gallop across the river and crocodiles can get trampled. DC captures a calf but the RagTags share with him and DC is left with a single mouthful. Frustrated with his small portion, DC drives the gang away. Theft is a viable strategy in the Grumeti. The RagTags follow DC when he tries to hoard his next prize. When DC spots one of the gang members and gives chase, the RagTags move in and steal the carcass.DC finds another opportunity on the Rocks, Zone 4. Wildebeest are forced to walk slowly to avoid tripping and falling. DC causes panic in the ranks and grabs a calf.This time he won't share. He flicks the calf until the head tears right off the neck. Exhausted from the hunt, DC is forced to rest and recharge. He's not alone. This pool belongs to a hippopotamus. Luckily the hippo is more curious that confrontational and he leaves DC alone. As the season moves on, the Grumeti River dries up. Only the tail-enders of the herd remain and DC needs one last kill before the herds disappear for good.On the Mara River the water itself is so treacherous that many animals die while crossing. Carcasses pile up on the riverbank, and the crocs here can scavenge long after the wildebeest have left. DC will have to hunt if he wants a stockpile. When the herds unexpectedly drink at the hippo pool, DC sets up for a Pit Stop attack. But suddenly they start to cross and it becomes a Rock Crossing!Wildebeest trample over him but he strikes a big wildebeest bull and holds tight. The hippo pool is not deep enough for a quick death. But DC outlasts the wildebeest in the tug-of-war.

This report shows how the famous Japanese green tea is cultivated, explores its healing power and explains how deeply the tea has penetrated Japanese society. For the Japanese people, green tea is more than just an ordinary beverage. It is the key to the national culture - it combines enjoyment, philosophy and the art of living. In springtime, the entire country waits for the first flush, the very first harvest of the precious Sencha tea from the island of Kyushu, the world's biggest organic tea production region.

High in the eastern mountains in a remote corner of India, Soumik encounters the Naga tribes. They teach him about their mysterious customs, chicken dances and head-hunting traditions, part of a unique identity at the brink of extinction. The Nagas wish to preserve.

In the world's oldest city of Varanasi, Soumik explores a neighbourhood that has produced five generations of Indian classical masters. He meets widowed women singers who have committed their lives to the Hindu God, Shiva, and a young drummer with the talent to make it big. Dedication to fading classical arts is formidable in this timeless city of religion, tradition and rising commercial interests.

Seg 1 Carrion flowers. Carrion flowers are the unorthodox perception of flowers for they are rare, big, and very unpleasant. Other terms are stink flowers and corpse flowers. The biggest flower in the world, rafflesia arnoldii, is a carrion flower. These flowers are difficult to find and reproduce and could breed through cross-pollination by attracting flies and dung beetles. Seg 2 Aposematism. Aposematism is a form of signalling that enables protection for both preys and predators by giving signs of poison and danger through showing off the bright colors and patterns on their epidermal layers that become associated with inedibility. Some species have developed mimicry based on aposematism in order to avail the protection aposematic colors give. Seg 3 Cuckoo Misdirection. Cuckoo misdirection demonstrates the mimicking abilities of a female cuckoo in order to find host nests to hatch her eggs. The female mimics a cry of a predator bird in order to frighten the hosts, leaving them vulnerable, thus the cuckoo can seize the chance to drop her egg on a host nest. Seg 4 Pheromones. Animal pheromones are the chemicals secreted and released by different species to communicate with other organisms. There are various types serving different purposes, ranging from reproduction, to trailing, to alarms. Some pheromones are also specific to one species of animals. Seg 5 Deimatic Behavior. Deimatic behavior is another type of defensive behavior in animals that also involves mimicry. It's the opposite of aposematism because while aposematism works by blatantly showing or signalling its danger or unpalatability, deimatic behavior relies on the element of surprise to startle predators in

From the streets of Soweto to the colonial Union Building, the metro area of Joburg is a mix of architecture, people and traditions. Johannesburg is more than just a big city—it's also home to one of the world's best safari parks.

As a new year starts in the heart of Africa, the rainy season has come to the Okavango Delta in Botswana, and with it begins a season of plenty and the luxury of permanent and abundant water sources. In South Africa's Hluhluwe-Imfolozi Game Reserve, a group of rare samango monkeys take advantage of the abundant fruit born by a large Natal fig tree. In Thailand, a group of rhesus macaques have discovered a mango tree, and are busy feeding and stuffing their throat pouches with the fruit. Back in the Okavango Delta, the rains have also brought large buffalo herds back to the Xakanaxa area, the territory of a powerful pride of lions. Life and death are also a close-run thing for young gannet fledglings on their massive breeding colony of 50.000 birds on Malgas Island off the South African coast. As the young birds attempt to spread their wings and take to the air, some end up in the water. Many young animals have to run a gauntlet early on in life, and as a young loggerhead turtle hatches out of its egg and emerges from the sand on a beach in Mozambique, it faces a gruelling journey from its nest on the beach down to the sea. African penguins, too, are adapted to life at sea, but rest, breed and mate on land. Penguins elsewhere in the world face an almost unbelievable challenge to breed and rear their young. When it comes to raising animals, the African plains are no more forgiving than the sub-Antarctic. At this time of year, the Serengeti plains in Tanzania are teeming with herds of wildebeest and zebra with their young. Predators are never far away. In a Thai forest, stingless bees are busy building a cone-shaped nest in a tree, combining forces for the greater good of the colony. Kamfers Dam in South Africa is one of only four breeding colonies of Lesser Flamingos, at times reaching up to 50.000 birds. The sun sets over the spectacular sight of thousands of flamingos, straining the water for food and taking to the air.

The discovery in Jerusalem in 2007 of a tomb said to belong to the family of Jesus of Nazareth is just the latest in a long line of extraordinary finds which have recently come to light in the Holy Land. But not all these finds are quite what they seem. Both a stone tablet said to come from the Temple of Solomon, and an ossuary apparently belonging to the brother of Jesus, have been declared fakes. The official investigation then uncovered dozens of other fakes, and attention eventually focussed on one of the most revered objects in Israel: the ivory pomegranate. This artefact has been in the Israel Museum for nearly twenty years. Like the stone tablet, it too was linked to the Temple of Solomon – and astonishingly it too, investigators concluded, was fake. As forensic scientists now turn their attention to the ossuaries from the 'Jesus family tomb', Israeli archaeologists are left fearing that history and science is being repeatedly distorted, and they face a challenge to separate fact from fiction.
