Visit the ghostly villages surrounding Chernobyl (abandoned by humans after the 1986 nuclear disaster), travel to remote islands off the coast of Maine to search for abandoned towns that have vanished from view in only a few decades, then head beneath the streets of New York to see how subway tunnels may become watery canals. A visual journey, LIFE AFTER PEOPLE is a thought provoking adventure that combines movie-quality visual effects with insights from experts in the fields of engineering, botany, ecology, biology, geology, climatology, and archaeology to demonstrate how the very landscape of our planet will change in our absence.

(Click CC for subtitles) Charged with overseeing Israel's war on terror-both Palestinian and Jewish- the head of the Shin Bet, Israel's secret service is present at the crossroad of every decision made. For the first time ever six former heads of the agency agreed to share their insights and reflect publicly on their actions and decisions. The Gatekeepers offers an exclusive account of the sum of their success and failures. It validates the reasons that each man individually and the six as a group came to reconsider their hard-line positions and advocate a conciliatory approach toward their enemies based on a two-state solution.

Blue whales are the largest animals to ever live on earth, yet they are difficult to find or track. Even some of the locations where they birth their young are great secrets. Join some of the world's eminent blue whale scientists as they embark on a revolutionary mission to identify and tag California blue whales as they migrate to a spot known as the Costa Rica Dome. This incredible voyage yields unforgettable new footage and insight into these amazing creatures' lives. Scientists use DNA analysis, recordings of whale songs, homing devices, and sea dives to shed light on the blue whale's breeding and birthing habits

The definitive discourse with Noam Chomsky on the defining characteristic of our time - the deliberate concentration of wealth and power in the hands of a select few. Chomsky unpacks the principles that have brought us to the crossroads of historically unprecedented inequality - tracing a half century of policies designed to favour the most wealthy at the expense of the majority. "Requiem for the American Dream" is profoundly personal and thought provoking. Chomsky provides penetrating insight into what may well be the lasting legacy of our time - the death of the middle class, and swan song of functioning democracy. A potent reminder that power ultimately rests in the hands of the governed, "Requiem for the American Dream" is required viewing for all who maintain hope in a shared stake in the future.

The human eye is a remarkable piece of precision engineering, but it is also extremely limited. Beyond the narrow range of light that makes up the familiar colours of the rainbow is a vast spectrum of light, entirely unseen. Richard Hammond does just that, using ground-breaking new imaging technologies to take the viewer on a breath-taking journey of discovery beyond the visible spectrum, seeing the world, quite literally, in a whole new light. From death-defying aerial repairmen in the United States using ultraviolet cameras to seek out an invisible force that lurks unseen on power lines, to German scientists unlocking the secrets of animal locomotion with the world's most powerful moving x-ray camera, to infrared cameras that can finally reveal the secrets within a humble beehive, he shows how new technologies are letting us see our world anew.

On November 25th, 1915, Einstein published his greatest work: General Relativity. The theory transformed our understanding of nature’s laws and the entire history of the cosmos, reaching back to the origin of time itself. Now, in celebration of the 100th anniversary of Einstein’s achievement, discover the inside story of Einstein’s masterpiece". The story begins with the intuitive thought experiments that set Einstein off on his quest and traces the revolution in cosmology that is still playing out in today’s labs and observatories. Discover the simple but powerful ideas at the heart of relativity, illuminating the theory—and Einstein’s brilliance—as never before. From the first spark of an idea to the discovery of the expanding universe, the Big Bang, black holes, and dark energy, NOVA uncovers the inspired insights and brilliant breakthroughs of “the perfect theory.”
