Épisode 4 - Ebola: The Plague Fighters

6 février 1996

AKA Inside an Outbreak The Ebola filovirus causes a very deadly and highly contagious disease. Outbreaks thus far have been limited due to the implementation of strict isolation, sterilization, and waste disposal procedures; the remoteness of areas in which the outbreaks appeared; and the fact that the virus kills so quickly that many of its victims die before it can be transmitted. Most recently, the Ebola virus struck in the city of Kikwit in Zaire, Africa, in early 1995 and killed almost 250 people before it was contained. Medical experts and relief workers went to work quickly to locate victims, to provide educational and prevention services to neighbors and families, and to research the Ebola virus.

Épisode 2 - Mysterious Mummies of China

20 janvier 1998

Pendant longtemps, historiens et archéologues ont estimé que les échanges entre la Chine ancienne et l’Occident n’avaient pas eu lieu avant la fin du IIe siècle avant J.-C., en raison des barrières naturelles que constituent l’Himalaya et le désert de Taklamakan. Cette théorie est aujourd’hui remise en question par l’étude minutieuse de certains vestiges remarquables. Un récipient en argent, retrouvé sur le site du tombeau du roi Liu Fei, arbore un motif embossé répandu dans le monde hellénique au IIIe siècle avant notre ère, mais inconnu de l’art chinois à cette époque. En revanche, tout laisse à penser que le métal utilisé provient du sud-est de la Chine. D’autre part, des fragments de tissus rappelant une technique de tissage mise au point par les Celtes ont également été exhumés sur un site de fouilles. Mais la découverte la plus probante est certainement celle des momies du bassin de Tarim, excavées dans un cimetière du désert de Taklamakan, dont les plus anciennes remontent à quatre mille ans. Des tests ADN et des analyses morphologiques certifient que certains visages seraient de type européen avec des cheveux bruns ou blonds. Se pourrait-il alors que la célèbre armée des soldats de terre cuite enfouie dans le mausolée du premier empereur chinois à Xian, ait été inspirée par la culture grecque ? Quelle a donc été l’influence de l’Occident sur l’empire du Milieu ? C’est ce que nous propose de découvrir ce documentaire, en compagnie notamment de l’archéologue américain Victor Mair, spécialiste des momies.

Épisode 3 - Supersonic Spies

27 janvier 1998

The race to build the world's first supersonic passenger airliner led to a massive espionage effort during the Cold War between the Soviet Union and the west.

Tapping into the clearly demonstrated affection we all have for our pets, this program will offer an offbeat, sometimes humorous, sometimes sad portrait of pets, their owners, and the veterinarians who treat our beloved animals' ailments. From race horses under the knife for cancer treatment, to Manhattan hounds on Prozac, to anorexic boa constrictors, we will show how cutting edge veterinary medicine is saving lives, and draw viewers into the mini-dramas that unfold each day in homes, in zoos, and in veterinary hospitals across the country.

Épisode 5 - The Brain Eater

10 février 1998

In this scientific mystery, NOVA ventures to the front lines of medical research where scientists are scrambling to understand the strange new ailment popularly known as "mad cow disease." Highly infectious and incurable, this disease has claimed the lives of nearly a million cattle in Britain, and a variant is responsible for a handful of deaths in humans. Millions more people may have been exposed, and now the race is on to determine if we are on the brink of another deadly epidemic like AIDS or Ebola. What scientists are finding is making them rethink many fundamental assumptions about epidemiology and may hold startling implications for public health in the future.

Épisode 6 - Everest - The Death Zone

24 février 1998

NOVA treks with a group of Himalayan climbers in their quest to reach the summit of Everest, along the way exploring in never-before-conducted tests how extremes of weather and altitude affect the human mind and body. Why do some people succumb so quickly to the ills caused by high altitude while others do not? Does exposure to extreme hypoxia—or lack of oxygen—take a lasting toll on the mind and body? Images of the brain scanned before and after the expedition may reveal truths about the physical traumas suffered in an oxygen-depleted environment, and give us new insight into why the tallest mountain in the world has claimed so many victims.

Épisode 7 - Search for the Lost Cave People

31 mars 1998

NOVA follows an international team of archaeologists and spelunkers into the Rio la Venta Gorge deep in the Chiapas jungle of Central America. In a rugged canyon they find caves filled with startling remains of a people called the Zoque who lived hundreds of years before the Maya. The extreme inaccessibility and relative dryness of the caves has preserved rare artifacts including bones, clothes, rope, and jewelry. Moving downstream from the caves the team finds a legendary city hidden in a tangle of jungle vines. Evidence of the Zoque's sophisticated writing system and their practice of ritualistic cannibalism and child sacrifice is shedding new light on a little known civilization.

Erectile dysfunction affects an estimated 52% of men between the ages of 40 and 70.

Épisode 11 - Lost At Sea: The Search For Longitude

6 octobre 1998

In 1714, following a maritime disaster, British Parliament offers £20,000 for the first reliable method of determining longitude on a ship at sea. It's known that longitude can be found by comparing a ship's local time to the time at the port of origin. The challenge is finding a clock—a chronometer—that can keep time at sea, where temperature changes, humidity, gravity and a ship's movement affect accuracy. NOVA chronicles the seventeenth-century journey to determine longitude.

Épisode 12 - Chasing El Niño

13 octobre 1998

A massive planet-sized machine controls our weather day-to-day, and our climate season-to-season. It takes an event of staggering proportions to disrupt a machine this large and powerful, a juggernaut with more energy than a million nuclear bombs. Signs now indicate that such an event is underway - El Niño. More than a series of storms stunning the California coastline, El Niño is second only to the seasons in its effect on global weather. In a P-3 off the coast, a team plunges into a storm front to explore its cause and effects. In a boat off the Galapagos, an array of buoys are checked for temperature and current data. On a mountan in Peru, signs of the devastation of past El Niños are revealed. As scientists push to extremes to explore this phenomenon, they understand for the first time the extent to which all the world's weather is connected, and just how delicate is the balance.

24 novembre 1998

This is the bizarre and fascinating story of the remains of Inca culture, frozen for posterity high in the mountains of the Andes. Evidence has emerged of sacrifice to the mountain gods, whose existence dominated the civilization over 500 years ago. The film traces the frozen bodies of children uncovered by archaeologists in South America, and follows an archaeological expedition to a high-altitude sacred site in search of ritual remains and another body. How did they come to be there? Why did they go to their deaths willingly? What was the religious framework that dictated their sacrifice to fierce gods?

Épisode 17 - Ice Mummies (2): Siberian Ice Maiden

24 novembre 1998

The Siberian Ice Maiden, discovered in the Pastures of Heaven, on the high Steppes, is believed to have been a shamaness of the lost Pazyryk culture. She had been mummified and then frozen by freak climatic conditions around 2400 years ago, along with six decorated horses and a symbolic meal for her last journey. Her body was covered with vivid blue tattoos of mythical animal figures. Together with the newly discovered body of a man, nicknamed "Conan," her body has now been restored, and is providing new clues to the role and power of women in the nomadic peoples of ancient Siberia.

Épisode 18 - Ice Mummies (3): Return of the Iceman

24 novembre 1998

Cutting-edge science and archaeology are reconstructing the life and culture of The Iceman—the 5000-year-old frozen corpse found buried in the ice of the Alps. By analyzing every inch of the Iceman's body and the tools and equipment found with it, scientists are piecing together the most complete picture yet of the late Stone Age in this part of Europe. X-ray, CAT scan, and microscopic analysis of this spectacular find is revealing where the iceman lived, what he ate, and how he may have died; nuclear physics reveals that the Iceman's hair was contaminated with arsenic and copper, suggesting he was involved in copper production centuries before it was known to exist in the region.

Épisode 19 - Leopards of the Night

Night stalkers by nature, leopards are observed both by night and day, using state-of-the-art camera equipment, to reveal never before seen hunting behavior. Filmed in the Luangua Valley in Zambia, Leopard reveals the challenges and dangers faced daily by these beautiful animals. Shadowed by hungry hyenas in pursuit of leftovers, and stalked by lumbering crocodiles hoping to tackle a lone leopard on a kill, how can they hope to challenge such beasts?

Épisode 20 - The Perfect Pearl

29 décembre 1998

The pearl—the only gem produced by a living animal—has long carried a certain allure. Yet the best mollusk for making this gem—the pearl oyster—doesn't always produce a pearl, and even then, the pearls are rarely perfectly round. It wasn't until the late nineteenth century, when a Japanese scientist discovered a technique to incite oysters to produce these gems, that an industry was formed. Inducing an oyster to create a pearl is only half the battle—the oyster then needs a nutrient-rich, open environment in which to grow. This NOVA program looks at the science of pearl farming, follows efforts of oyster farmers trying to cope with growing problems of pollution and overcrowding, and considers the shifting sands of dominance within the pearl industry.

Épisode 1 - The Beast of Loch Ness

12 janvier 1999

Is it just a fairy tale, or could a primeval beast lurk in the deep, dark waters of a Scottish lake? Since it was first reported more than 60 years ago, hundreds claim to have witnessed the Loch Ness Monster, while one scientist after another has brought the latest technology to the loch to probe the phenomenon. Twenty-five years after their first, groundbreaking expedition to Loch Ness, NOVA joins two American scientists as they return to Scotland for one last go at Nessie. During a three-week expedition, they use state-of-the-art sonar and sensitive underwater cameras in an attempt to track down and identify the elusive beast. Biologists study the ecosystem of the loch to determine if it could support a large animal. Geologists study its history, looking for clues about what kind of creature might have colonized it, and when. NOVA examines the photographic evidence in the case. And eyewitnesses vividly recount their sightings. Could this legendary creature be real, perhaps a relic from the time of dinosaurs? Or is it a shared illusion—a product of myth, mirage and wishful thinking?

Épisode 2 - Submarines, Secrets & Spies

19 janvier 1999

Les mystérieux et tragiques accidents fie sous-marins et les missions d'espionnage risquées qui ont contribue à gagner la guerre froide.

Épisode 3 - Surviving AIDS

2 février 1999

The past five years have seen remarkable progress in both treatment and basic understanding of the human immunodeficiency virus (HIV) that causes AIDS. In laboratories and clinics across the country and around the world, scientists and doctors have pooled their expertise to keep people infected with HIV alive and disease-free longer than was imaginable at the start of the epidemic. And now, through what may well be an unprecedented cross-fertilization process among molecular biologists, immunologists, geneticists, and practicing physicians, a series of discoveries about HIV-infected patients who have successfully fought off AIDS for as long as 20 years are being closely analyzed for clues to the ultimate goal in this fierce scientific battle—a vaccine. NOVA tells the story of this ongoing battle through the experiences of patients like Robert Massie, a "long-term non-progressor." Massie, a 43-year old environmental activist and Episcopalian minister was infected by a blood transfusion in 1978 and after an acute period of illness, somehow his immune system has kept the HIV virus at bay without drugs. Surviving AIDS reveals the scientific community engaged in an enormous and ongoing struggle, with discoveries traveling from labs to patients and back. And NOVA brings together the most promising research with compelling human stories of the patients and doctors who are devoting themselves to unraveling one of the most complicated mysteries in scientific history.

Épisode 11 - Time Travel

12 octobre 1999

Is time travel anything more than sci-fi fantasy? Many leading physicists now believe that time travel is not only possible in theory but are discussing how to build a time machine. Physicist Kip Thorne tells NOVA how humankind's infinitely advanced descendants might go about achieving it with "quantum wormholes" and some "exotic matter." Demonstrating that faster-than-light travel may be possible, German physicist Guenter Nimtz claims to have transmitted Mozart's 40th Symphony across his lab at 4.7 times the speed of light. Impossible, yes, but recorded by NOVA's cameras and perhaps another step on the road to reaching the future or the past. The truth about time travel is wrapped up in the detail of how our universe works and how it all began. Mind-boggling as these perspectives are, NOVA dramatizes them in a playful and visually dazzling style that will captivate viewers and sweep them along on the ultimate thrill ride.

Épisode 12 - The Killer's Trail

19 octobre 1999

The death of Marilyn Sheppard in 1954 is one of the most famous unsolved murders in America. The indictment of her husband, Dr. Sam Sheppard, quickly became the "Trial of the Century," then the "Re-Trial of the Century," making a celebrity out of lawyer F. Lee Bailey. Although most of the forensic evidence gathered in 1954 was ignored during Sheppard's trial, it is being re-examined with today's advanced technology. Like an intricate puzzle, the clues come together to overturn previous assumptions about the killer and point to an entirely new suspect. NOVA assembles a notable team of experts—including Barry Scheck, a well-known lawyer from the O.J. Simpson trial—and builds a precise replica of the Sheppard house, complete with the original furniture. With this unique revisiting of a vanished crime scene, NOVA investigates a horrifying and sensational milestone in forensic science.

Épisode 13 - Island of the Spirits

2 novembre 1999

In the far north of Japan, thrust out into the north Pacific, is the remote island of Hokkaido. It's a land of towering volcanoes and steaming lakes, marshy valleys and fairy tale forests. Among this magical scenery, where summers are brief and winters are fierce, lives an extraordinary spectrum of life, found nowhere else in Japan. Here among the coastal lowlands, grizzly bears plunge into icy streams for salmon, Japanese cranes perform balletic courtship dances to one another, the rare and enormous Blakistons fish owl swoops on flying squirrels, and white-tailed eagles scan the rugged ocean cliffs for unsuspecting seabirds. HIgh on the mountains Asiatic pikas, arctic hares and Siberian chipmunks gather food, ever-watchful for the predatory sable. We think of Japan as a highly-populated, ultra modern society, and yet it remains a highly spiritual place where wildlife is treasured and carefully protected. Weaving Ainu legend with fascinating natural behavior, this film will follow the lives of Hokkaido's special creatures through the seasons, to capture the true essence and beauty of this other-worldly place.

Épisode 14 - Decoding Nazi Secrets

9 novembre 1999

Most historians agree that by enabling Allied commanders to eavesdrop on German plans, Station X shortened the war by 2 or 3 years. Its decoded messages played a vital role in defeating the U-boat menace, cutting off Rommel's supplies in North Africa, and launching the D-Day landings. Now, for the first time on television, a 2-hour NOVA Special tells the full story of Station X, drawing on vivid interviews with many of the colorful geniuses and eccentrics who attacked the Enigma. Wartime survivors recall such vivid episodes as the British capture of the German submarine U-110; one of its officers describes how he saved a book of love poems inscribed to his sweetheart but failed to destroy vital Enigma documents on board. "Decoding Nazi Secrets" also features meticulous period reenactments shot inside the original buildings at Station X, including recreations of the world's first computing devices that aided codebreakers with their breakthroughs. Station X not only helped reverse the onslaught of the Third Reich, but also laid the groundwork for the invention of the digital computer that continues to transform all our lives.

Épisode 15 - Voyage Of Doom

23 novembre 1999

Buried in mud beneath the shallow waters of Matagorda Bay in Texas, lay a glorious remnant of one of the most ill-fated voyages of the Age of Discovery. After years of searching the area, nautical archaeologists doing a magnetometer survey honed in on a promising site. And on the first day of diving, they were astounded to feel the distinctive outlines of a cannon, and sense the massive size of the wreck. When the cannon was hauled from the water, their hunch was confirmed: This ship, called La Belle, belonged to the 17th Century French explorer Robert Cavelier de La Salle. NOVA follows the building of a coffer dam and subsequent complete excavation of this remarkable site. Preserved were not only armaments and trade beads, but also a wealth of organic material—the wooden hull, leather shoes, and even a skeleton—that brings the voyage to life.

But their crucial breakthrough depended on the pioneering work of another biologistÐRosalind Franklin. She would never know that Watson and Crick had seen a crucial piece of her data without her permission. This was an X-ray image, ''Photo 51,'' that proved to be a vital clue in their decoding of the double helix. 50 years later, NOVA investigates the shocking truth behind one of the greatest scientific discoveries and presents a moving portrait of a brilliant woman in an era of male-dominated science. Sadly, Franklin never lived to see her vital role in the discovery vindicated. While Watson and Crick went on to win the Nobel Prize in 1962, Franklin died in 1958, at 37, from ovarian cancer; and the Nobel is not awarded posthumously. Hear the inside story from Maurice Wilkins, the colleague who showed her crucial x-ray to Watson; Raymond Gosling, FranklinÕs Ph.D. student with whom she made Photo 51; and Nobel Prize winner Sir Aaron Klug, FranklinÕs last collaborator, who shows new evidence of just how close Franklin came to making the vital double helix discovery herself.

Épisode 1 - Welcome To Mars

4 janvier 2005

The great PBS science series Nova scores another hit with Mars: Dead or Alive, capturing all the excitement surrounding the Mars rover landings of early 2004. Originally broadcast just as the first of the twin rovers (”Spirit” and “Opportunity”) was experiencing temporary communication problems with Earth-bound mission controllers, this riveting hour-long episode chronicles the risky $820 million Mars Exploration Rover (MER) project from design to touchdown, dramatically illustrating (through the use of detailed simulations and sophisticated computer animation) the considerable chances of failure–a nail-biting gamble considering that fully two-thirds of all previous Mars missions never reached their destination. Through rigorous testing and initial failure of the MER parachute system to the celebrated transmission of pristine photos from the “Spirit” landing site, we see just how intensely complex and emotionally involving the missions are, especially for Cornell University astronomer and lead MER scientist Steve Squyres and his devoted team of colleagues at Pasadena's Jet Propulsion Laboratory. Careers are on the line as technical problems accumulate, and one feels the same mixture of dread, anxiety, and elation that accompanied the historic return of Apollo 13. A bonus interview with Mars-mission pioneer Donna Shirley puts everything into resonant perspective, celebrating science and the MER missions as an essential human endeavor. Inside NASA's risky field trip to the Red Planet. Two-thirds of all spacecraft previously launched to Mars never reached their destination. Now, in a pioneering and risky mission, twin rovers named Spirit and Opportunity hurtle toward Mars at 12,000 miles per hour, with Spirit scheduled to touch down first. In the final “six minutes of terror” a parachute will open, giant protective airbags will inflate around the lander, and retrorockets will fire for a few seconds before Spirit is cut loose, bouncing its way to wha

Épisode 2 - The Boldest Hoax

11 janvier 2005

For decades, a fossil skull discovered in Piltdown, England, was hailed as the missing link between apes and humans. Entire careers were built on its authenticity.

Zoom sur la carte du Vinland, une mappemonde représentant le monde supposé au XVe siècle. Sur ce document se trouvent le Groenland et une autre île, le Vinland, évoquant les contours approximatifs de l'Amérique du Nord. Cette découverte renforce l'hypothèse que les Européens auraient eu connaissance des voyages des Vikings au XIe siècle, soit quatre siècles avant la découverte du Nouveau Monde par Christophe Colomb en 1492. Mais l'authenticité de cette carte conservée au sein de l'université de Yale est contestée. Grâce à des moyens techniques poussés, des analyses du contenu, de l'encre et du papier ont été effectuées.

Épisode 8 - Mystery Of The Megaflood

20 septembre 2005

It was the greatest flood of the past two million years, and it posed a giant scientific riddle. A maverick geologist became convinced that thousand-foot-deep floodwaters had scoured out vast areas of the American northwest near the end of the last ice age. Mainstream scientists scorned his theory while he searched patiently for answers to what could have triggered such an inconceivably violent event. Finally, an ingenious solution silenced the skeptics: traces of an enormous ice dam half a mile high, which had blocked a valley in present-day Montana and created an enormous lake behind it. With the help of stunningly realistic animation, NOVA takes viewers back to the Ice Age to reveal what happened when the dam broke, unleashing a titanic flood that swept herds of woolly mammoth and everything else into oblivion.

Épisode 9 - Sinking The Supership

11 octobre 2005

Exactly 100 years ago, Albert Einstein grappled with the implications of his revolutionary Special Theory of Relativity and came to a startling conclusion: mass and energy are one, related by the formula E = mc2. Among Einstein's ideas, E = mc2 is by far the most famous. Yet how many people know what it really means? In a thought-provoking and engrossing documentary, Einstein's Big Idea illuminates this deceptively simple formula by unrevealing the story of how it came to be.

This docudrama looks at Isaac Newton's discoveries in mathematics, physics and optics, as well as his lesser known pursuit of alchemy and hidden meanings in the Bible.

Épisode 14 - Storm That Drowned A City

22 novembre 2005

The narration is melodramatic, some of the interviews feel stagy--but the footage of Hurricane Katrina and its horrendous aftermath is staggering. Hurricane Katrina - The Storm That Drowned a City, a NOVA special, begins a year earlier, when a team of scientists created a computer simulation of the destructive effect a powerful storm could have on New Orleans and the Gulf Coast. Though local officials took it seriously, the federal response was skeptical, and little was done to strengthen the city's protection. Using a combination of remarkable video of the developing storm and interviews with scientists, city residents (black and white), and member of the Army Corps of Engineers, Hurrican Katrina builds a compelling story of the disaster as it unfolded. Sophisticated graphics explain how hurricanes form and how the levees failed. The special touches lightly on the possibility that global warming may be exacerbating the intensity of hurricanes, but shies away from the political storm of the meager federal response to the devastation of New Orleans. The result is a vivid, detailed description of the natural disaster, but an incomplete portrait of the social one. --Bret Fetzer

Épisode 13 - Judgment Day: Intelligent Design On Trial

13 novembre 2007

In this two-hour special, NOVA captures the turmoil that tore apart the community of Dover, Pennsylvania in one of the latest battles over teaching evolution in public schools. Featuring trial reenactments based on court transcripts and interviews with key participants, including expert scientists and Dover parents, teachers, and town officials, "Judgment Day: Intelligent Design on Trial" follows the celebrated federal case of Kitzmiller v. Dover School District. This program was coproduced with Paul G. Allen's Vulcan Productions, Inc. In 2004, the Dover school board ordered science teachers to read a statement to high school biology students suggesting that there is an alternative to Darwin's theory of evolution called intelligent design–the idea that life is too complex to have evolved naturally and therefore must have been designed by an intelligent agent. The teachers refused to comply. Later, parents opposed to intelligent design filed a lawsuit in federal court accusing the school board of violating the constitutional separation of church and state. "There was a blow-up like you couldn't believe," Bill Buckingham, head of the school board's curriculum committee, tells NOVA. Buckingham helped formulate the intelligent-design policy when he noticed that the biology textbook chosen by teachers for classroom use was, in his words, "laced with Darwinism." NOVA presents the arguments by lawyers and expert witnesses in riveting detail and provides an eye-opening crash course on questions such as "What is evolution?" and "Is intelligent design a scientifically valid alternative?" Kitzmiller v. Dover was the first legal test of intelligent design as a scientific theory, with the plaintiffs arguing that it is a thinly veiled form of creationism, the view that a literal interpretation of the Bible accounts for all observed facts about nature. During the trial, lawyers for the plaintiffs showed that evolution is one of the best-tested and most thoroughly con

Épisode 1 - Absolute Zero: The Conquest Of Cold (1)

8 janvier 2008

Our mastery of cold is something we take for granted, whether it s air conditioning and frozen food or the liquefied gases and superconductivity at the heart of cutting-edge technology. But what is cold? How do you achieve it, and how cold can it get? This two-part NOVA special brings the history of this frosty fascination to life with brilliant dramatic recreations of high moments in low-temperature research and the quest for ever-lower notches on the thermometer. The first hour, The Conquest of Cold, opens in the 1600s when the nature of cold and heat was a complete mystery. Were they different aspects of the same phenomenon? The experiments that settled these questions helped stoke the Industrial Revolution. In the second hour, The Race For Absolute Zero dramatizes the titanic rivalry between Scottish researcher James Dewar and Dutch physicist Heike Onnes, who plunged cold science to the forbidding realm at which oxygen and then nitrogen turn into liquids. The race continues today as scientists pioneer super-fast computing near absolute zero the ultimate chill of -459.67° F where atoms slow to a virtual standstill.

Trois décennies plus tard, il est loin d’être achevé. Restaurer ce monument aux proportions parfaites tient du casse-tête. Construit entre 447 et 438 avant J.-C., le Parthénon a été conçu comme l’écrin architectural d’une gigantesque statue d’Athéna. L’harmonie de ses lignes repose sur un principe étonnant : contrairement aux apparences, aucune n’est droite ! D’où la difficulté que pose la restauration de cet édifice dont aucun élément n’est interchangeable. Coordonnée par l’architecte grec Manolis Korres, l’équipe de rénovation se retrouve face à une partie de puzzle géant, où les pièces sont des blocs de marbre qui se comptent par dizaine de milliers et pèsent dans les 10 tonnes.

Épisode 16 - The Bible's Buried Secrets

18 novembre 2008

Quand est né le judaïsme ? Quelles étaient les croyances des premiers Israélites ? Comment la Bible a-t-elle été écrite ? Ce documentaire confronte les investigations sur les textes religieux et les découvertes archéologiques en Terre sainte depuis la fin du XIXe siècle. Cette collaboration exceptionnelle entre chercheurs montre qu’à l’époque d’Abraham la première religion monothéiste était loin d’être une entité cohérente… La plupart des Israélites ont, par exemple, longtemps adoré des dieux païens. Par ailleurs, nombre d’entre eux pensaient que Dieu avait une épouse qui était elle-même une idole vénérée. Ce n’est qu’après la destruction de Jérusalem que les juifs, exilés à Babylone, ont commencé à concevoir l’existence d’un dieu unique et universel. C’est durant l’exil (entre 597 et 538 avant J.-C.) qu’ont été rédigés les cinq premiers livres de la Bible. Ces deux tragédies – la perte de Jérusalem et l’exil – ont constitué un terreau fertile sur lequel s’est développé un ensemble de croyances qui ont ensuite donné naissance au christianisme, à l’islam et à notre monde moderne.

In this high-action scientific adventure, NOVA and National Geographic investigate the mystery of the mighty ice sheets, whose still-unknown behavior will affect the fate of coastlines around the world.

Épisode 6 - Last Extinction (Megabeasts' Sudden Death)

31 mars 2009

What killed the mammoths? Near the end of the last ice age 13,000 years ago, these mighty beasts disappeared from North America together with some 35 other groups of mammals, including giant ground sloths, saber-tooth cats, and American lions. For four decades, debate has raged over the cause of their abrupt demise. In Last Extinction, NOVA presents an exclusive in-depth investigation of a bold and controversial new hypothesis, which suggests that a massive impact from space could be the culprit. According to the theory, an incoming comet broke up over North America in a devastating series of explosions, causing widespread forest fires and wiping out plants, animals, and prehistoric people. The evidence comes from a mysterious black mat layer discovered at more that fifty sites across the continent. The black mat contains exotic materials including rare microscopic nanodiamonds that are claimed to be the signature of an extraterrestrial impact. But other scholars question the evidence and argue that ancient hunters armed with a lethal stone weapon the Clovis spear point drove the giant beasts into oblivion. Still others believe the unstable climate at the end of the Ice Age was responsible. NOVA explores the dramatic new evidence of a cosmic explosion and the possibility that all three explanations may be correct.

The best-known scientific instrument in history was dying. After nearly 20 years in space and hundreds of thousands of spectacular images, the Hubble Space Telescope's gyroscopes and sensors were failing, its batteries running down, and some of its instruments were already dead. The only hope to save Hubble was a mission so dangerous that in 2004 NASA cancelled it because it was considered too risky.

Épisode 12 - Lizard Kings

20 octobre 2009

Though they may look like dragons and inspire stories of man-eating, fire-spitting monsters with long claws, razor-sharp teeth and muscular, whip-like tails, these creatures are actually monitor lizards, the largest lizards to walk the planet. With their acute intelligence — including the ability to plan — these lizards are a very different kind of reptile, blurring the line between reptiles and mammals. And even though these bizarre reptiles haven’t changed all that much since the dinosaurs, they are a successful species, versatile at adapting to all kinds of settings. “Lizard Kings” looks at what makes these tongued reptiles so similar to mammals and what has allowed them to become such unique survivors. But while the creatures can find their way around many different habitats, finding them is no easy task. Natural loners, and always on guard, they sense anything or anyone from hundreds of feet away. NOVA follows expert lizard hunter Dr. Eric Pianka as he tracks the elusive creatures through Australia’s heartland with cutting-edge “lizard cam” technology for an unparalleled close encounter with these versatile “living dragons.”

Épisode 13 - Becoming Human Part 1: First Steps

3 novembre 2009

Il y a plusieurs millions d'années, un évènement capital a eu lieu dans les plaines d'Afrique : des grands singes quadrupèdes se sont redressés et ont marché sur leurs seules pattes arrière. Ce changement de posture a petit à petit entrainé une évolution de leur cerveau et, au fil du temps, ces singes sont devenus des hommes. Les scientifiques savaient que la chose s'était produite, mais ils ignoraient quand et pourquoi. Du moins jusqu'à aujourd'hui. Cet épisode revient sur la découverte en Ethiopie en 2000 du fossile de Selam : une petite fille décedée a un âge estimé à 3 ans qui aurait vécu il y a environ 3,3 millions d'années.

Épisode 14 - Becoming Human Part 2: Birth of Humanity

10 novembre 2009

Il y a environ 2 millions d'années est apparue une nouvelle espèce dotée de capacités sans précédent dans le royaume animal : l'Homo Erectus, l'un des premiers représentants du genre humain.

Épisode 15 - Becoming Human Part 3: Last Human Standing

17 novembre 2009

L'Homo erectus, l'un des premiers représentants du genre humain, a le premier quitté l'Afrique il y a un peu moins de deux millions d'années. Les vagues migratoires successives ont notamment donné naissance à l'Homme de Flores en Indonésie, et plus tard, en Europe, à l'Homme de Neanderthal. Mais pourquoi ce dernier a-t-il disparu au moment de l'apparition de l'Homo sapiens ? Longtemps, les paléontologues ont supposé que les premières populations d'hommes modernes avaient fini par absorber les Neanderthaliens par métissage, mais aucune trace de l'ADN de l'Homme de Neanderthal n'existe dans nos gènes. Peu à peu repoussé vers des zones marginales, avec une technologie limitée au regard de ses besoins énergétiques énormes, l'Homme de Neanderthal a succombé à sa rencontre avec l'Homo sapiens, mieux adapté, plus inventif et beaucoup plus fort démographiquement.

Épisode 16 - What Are Dreams?

Épisode 17 - What Darwin Never Knew

29 décembre 2009

Les mécanismes de l'évolution et le rôle de l'ADN expliqués par les biologistes les plus éminents. Un documentaire fascinant et étonnamment accessible.Il y a cent cinquante ans, Charles Darwin révolutionne la science avec sa théorie de l'évolution. À partir de ses observations lors d'un voyage à travers le monde, le naturaliste met en évidence l'infinie variété des espèces. Étudiant parallèlement les embryons, il énonce les principes de la biologie évolutive : le concept de sélection naturelle fondée sur l'adaptation à l'environnement et la variation des individus. Mais les mécanismes de ces processus de mutation lui restent complètement obscurs. Un mystere qui, aujourd'hui, avec les progrès de la biologie et de la génétique, se dissipe. Revenant sur les bases de la théorie de Darwin en compagnie des plus éminents scientifiques (biologistes, généticiens, paléontologues, médecins...) qui font partager leurs expériences en laboratoire et sur le terrain, le documentaire explique les découvertes les plus récentes, notamment le rôle et le fonctionnement de l'ADN dans les mécanismes de l'évolution. LES MYSTÈRES DE L'ÉVOLUTION Pourquoi les oiseaux ont-ils des becs si différents ? Comment les poissons se sont-ils transformés en tétrapodes il y 3 000 000 d'années ? Pourquoi, alors que notre génome est identique à celui du chimpanzé à 99 %, sommes-nous si dissemblables ? Avec pour principal guide Sean B. Caroll, professeur reconnu en biologie moléculaire et en génétique, le documentaire parvient à expliquer simplement des mécanismes extraordinaires et complexes, tout en nous faisant partager le plaisir des chercheurs.

Épisode 3 - Riddles of the Sphinx

19 janvier 2010

Monumentale sculpture, le Sphinx est l'oeuvre monolithique la plus grande du monde. Sa signification demeure encore une énigme pour les égyptologues. Quelles sont les théories qui entourent sa réalisation ? Certains affirment qu'il fut sculpté avant les grandes pyramides. Sa tête d'origine était-elle celle d'un lion ? D'autres pensent que le visage du Sphinx représenterait celui de Khéops et qu'il aurait été édifié par son fils Djédefrê. Grâce à l'étude géologique du terrain du temple adjacent, il est possible d'en savoir plus sur le visage. L'étude approfondie des rites et écritures de cette époque permet également de définir que le Sphinx a été bâti à des fins religieuses pour le culte du soleil grandissant. Cela confirme l'importance de la vie après la mort dans l'Egypte ancienne.

Épisode 16 - Quest for Solomon's Mines

23 novembre 2010

Countless treasure-seekers have set off in search of King Solomon's mines, trekking through burning deserts and scaling the forbidding mountains of Africa and the Levant, inspired by the Bible's account of splendid temples and palaces adorned in glittering gold and copper. Yet to date, the evidence that has claimed to support the existence of Solomon and other early kings in the Bible has been highly controversial. In fact, so little physical evidence of the kings who ruled Israel and Edom has been found that many contend that they are no more real than King Arthur. In the summer of 2010, NOVA and National Geographic embarked on two cutting-edge field investigations that illuminate the legend of Solomon and reveal the source of the great wealth that powered the first mighty biblical kingdoms. These groundbreaking expeditions expose important new clues buried in the pockmarked desert of Jordan, including ancient remnants of an industrial-scale copper mine and a 3,000-year-old message with the words "slave," "king," and "judge."

Épisode 17 - Secrets Beneath the Ice

28 décembre 2010

Almost three miles of ice buries most of Antarctica, cloaking a continent half again as large as the United States. But when an Antarctic ice shelf the size of Manhattan collapsed in less than a month in 2002, it shocked scientists and raised the alarming possibility that Antarctica may be headed for a meltdown. Even a ten percent loss of Antarctica's ice would cause catastrophic flooding of coastal cities unlike any seen before in human history. What are the chances of a widespread melt? "Secrets Beneath the Ice" explores whether Antarctica's climate past can offer clues to what may happen. NOVA follows a state-of-the-art expedition that is drilling three-quarters of a mile into the Antarctic seafloor. The drill is recovering rock cores that reveal intimate details of climate and fauna from a time in the distant past when the Earth was just a few degrees warmer than it is today. As researchers grapple with the harshest conditions on the planet, they discover astonishing new clues about Antarctica's past—clues that carry ominous implications for coastal cities around the globe.

Épisode 1 - Deadliest Earthquakes

11 janvier 2011

In 2010, several epic earthquakes delivered one of the worst annual death tolls ever recorded. The deadliest strike, in Haiti, killed more than 200,000 people and reduced homes, hospitals, schools, and the presidential palace to rubble. In exclusive coverage, a NOVA camera crew follows a team of U.S. geologists as they enter Haiti in the immediate aftermath of the tragedy. The team hunts for crucial evidence that will help them determine exactly what happened deep underground and what the risks are of a new killer quake. Barely a month after the Haiti quake, Chile was struck by a quake 100 times more powerful, unleashing a tsunami that put the entire Pacific coast on high alert. In a coastal town devastated by the rushing wave, NOVA follows a team of geologists as they battle aftershocks to measure the displacement caused by the earthquake. Could their work, and the work of geologists at earthquake hot spots around the U.S., one day lead to a breakthrough in predicting quakes before they happen? NOVA investigates compelling new leads in this profound scientific conundrum.

"Smarter" concludes with a vision of the ultimate in "life-like" stuff: programmable matter that could create a duplicate of a human being.

Épisode 6 - Smartest Machine on Earth

9 février 2011

Augmenting human intelligence is a lot tougher than it looks, and the promise of "Hal" from 2001: A Space Odyssey is still just a fantasy. But scientists are edging closer with machines like "Watson," an IBM computing system that is gearing up for a first-of-its-kind challenge: taking on human contestants on the game show Jeopardy! With a brain the size of 2,400 home computers and a database of about 10 million documents, will Watson be able to compute its way to victory? Given the complexity of human language, could any computer truly understand it? It remains to be seen if this amalgam of circuits and silicon can really take us closer to the dream of a fully developed artificial intelligence, a truly "conscious" machine. Win or lose, the difficulty of mimicking the human thought process with software is showing artificial-intelligence researchers that there's more than one way to be "intelligent."

Épisode 7 - Crash of Flight 447

Épisode 2 - Bombing Hitler's Dams

11 janvier 2012

In 1943 a squadron of Lancaster bombers staged one of the most audacious raids in military history: destroying two gigantic dams in Germany’s industrial heartland and cutting the water supply to arms factories. Their secret weapon? A revolutionary bouncing bomb invented by British engineer Barnes Wallis. Wallis and the pilots of 617 Squadron—a lively mix of Britons, Australians, Americans, and Canadians—were hailed as heroes who dealt a mighty blow to the German war machine. Now, NOVA recreates the extreme engineering challenges faced by Wallis and the pilots. A crack team of experts, including dam engineers, explosives specialists, mechanics, and aircrew, steps into the shoes of the "dambusters" and attempts to overcome each of the obstacles the original team faced. They must adapt a vintage World War II DC-4 to carry a bomb the size of an oil drum, train to drop it from a dangerously low altitude in pitch darkness, and get it to bounce over obstacles and onto the target, a scale model the German dam struck by the original dambusters. Can they succeed in destroying the dam and unraveling the mysteries of the one-of-a-kind bouncing bomb?

Épisode 3 - 3D Spies of WWII

18 janvier 2012

During World War II, Hitler’s scientists developed terrifying new weapons of mass destruction. Alarmed by rumors of advanced rockets and missiles, Allied intelligence recruited a team of brilliant minds from British universities and Hollywood studios to a country house near London. Here, they secretly pored over millions of air photos shot at great risk over German territory by specially converted, high-flying Spitfires. Peering at the photos through 3D stereoscopes, the team spotted telltale clues that revealed hidden Nazi rocket bases. The photos led to devastating Allied bombing raids that dealt crucial setbacks to the German rocket program and helped ensure the success of the D-Day landings. With 3D graphics that recreate exactly what the photo spies saw, NOVA tells the suspenseful, previously untold story of air photo intelligence that played a vital role in defeating the Nazis.

Twenty million passengers embark on cruises each year, vacationing in deluxe "floating cities" that offer everything from swimming pools to shopping malls to ice skating rinks. And the ships just keep getting bigger: The average cruise ship has doubled in size in just the last ten years. Some engineers fear that these towering behemoths are dangerously unstable, and the recent tragedy of the Costa Concordia has raised new questions about their safety. Now, NOVA brings together marine engineering and safety experts to reconstruct the events that led up to famous cruise disasters, including the ill-fated Concordia, the Sea Diamond, and the Oceans.

Épisode 11 - Secrets of the Sun

25 avril 2012

It contains 99.9 percent of all the matter in our solar system and sheds hot plasma at nearly a million miles an hour. The temperature at its core is a staggering 27 million degrees Fahrenheit. It convulses, it blazes, it sings. You know it as the sun. Scientists know it as one of the most amazing physics laboratories in the universe. Now, with the help of new spacecraft and Earth-based telescopes, scientists are seeing the sun as they never have before and even recreating what happens at its very center in labs here on Earth. Their work will help us understand aspects of the sun that have puzzled scientists for decades. But more critically, it may help us predict and track solar storms that have the power to zap our power grid, shut down telecommunications, and ground global air travel for days, weeks, or even longer. Such storms have happened before—but never in the modern era of satellite communication. "Secrets of the Sun" reveals a bright new dawn in our understanding of our nearest star—one that might help keep our planet from going dark.

Épisode 13 - Forensics on Trial

17 octobre 2012

There is a startling gap between the glamorous television world of “CSI” and the gritty reality of the forensic crime lab. With few established scientific standards, no central oversight, and poor regulation of examiners, forensics in the U.S. is in a state of crisis. In "Forensics on Trial", NOVA investigates how modern forensics, including the analysis of fingerprints, bite marks, ballistics, hair, and tool marks, can send innocent men and women to prison—and sometimes even to death row. Shockingly, of more than 250 inmates exonerated by DNA testing over the last decade, more than 50 percent of the wrongful convictions stemmed from invalid or improperly handled forensic science. With the help of vivid recreations of actual trials and cases, NOVA will investigate today’s shaky state of crime science as well as cutting-edge solutions that could help investigators put the real criminals behind bars.

Épisode 14 - Mystery of Easter Island

7 novembre 2012

A remote, bleak speck of rock in the middle of the Pacific, Easter Island, or Rapa Nui, has mystified the world ever since the first Europeans arrived in 1722. How and why did the ancient islanders build and move nearly 900 giant statues or moai, weighing up to 86 tons? And how did they transform a presumed paradise into a treeless wasteland, bringing ruin upon their island and themselves? NOVA explores controversial recent claims that challenge decades of previous thinking about the islanders, who have been accused of everything from ecocide to cannibalism. Among the radical new theories is that the islanders used ropes to "walk" the statues upright, like moving a fridge. With the help of an accurate 15-ton replica statue, a NOVA team sets out to test this high-risk, seemingly unlikely theory—serving up plenty of action and surprises in this fresh investigation of one of the ancient world's most intriguing enigmas.

Épisode 15 - Ultimate Mars Challenge

In the aftermath of his 1927 solo transatlantic flight, Colonel Charles Augustus Lindbergh–the Lone Eagle–became the most famous human being on earth. And when he and his lovely wife Anne produced an adorable baby son, Charlie, an eager press quickly dubbed him Little Lindy or sometimes just the Eaglet. But on the evening of March 1, 1932 Lucky Lindy's luck ran out. Bold kidnappers snatched his baby from the family home near Hopewell, New Jersey, while everyone in the house was awake. Negotiations with the kidnappers stretched out for weeks. But Little Charlie never came back. His body was discovered not five miles from Hopewell. Now, NOVA is reopening one of the most intriguing, grisly, and confounding crime mysteries of all time as a team of expert investigators employ state-of-the-art forensic and behavioral science techniques in an effort to determine what really happened to Lindbergh's baby and why.

Épisode 5 - Building Pharaoh's Chariot

6 février 2013

Des illustrations retrouvées sur les murs de tombeaux et de temples égyptiens, datant d’il y a 3 600 ans, montrent des pharaons au combat, s’élançant fièrement dans la bataille sur des chars tirés par des chevaux. Selon certains historiens, l’apparition de ce véhicule, qui s’apparente à une véritable révolution technologique, aurait permis aux rois d’Égypte de multiplier les conquêtes et de consolider les frontières du Nouvel Empire. En quoi ces chars étaient-ils si originaux ? Quelle vitesse pouvaient-ils atteindre et dans quelle mesure étaient-ils maniables ? Ont-ils réellement joué un rôle décisif dans la stratégie expansionniste des pharaons ? Défi scientifique C’est pour tenter d’élucider ces énigmes qu’une équipe d’archéologues, d’ingénieurs, de menuisiers et de dresseurs de chevaux a entrepris la construction de deux répliques de chars égyptiens : le premier véhicule, léger, est inspiré des modèles observés dans le tombeau de Toutankhamon ; le second, plus lourd et à la décoration élaborée, correspond à la description du char utilisé par Touthmôsis III lors de la bataille de Megiddo. Roues à rayons, ressorts, amortisseurs, barres antiroulis, rétroviseurs de forme convexe, toute l’architecture a été étudiée à la loupe et reconstituée. Après plusieurs mois d’efforts, l’équipe est prête à lancer les chars à pleine vitesse dans le désert…

Épisode 8 - Mind of a Rampage Killer

20 février 2013

What makes a person walk into a theater or a church or a classroom full of students and open fire? What combination of circumstances compels a human being to commit the most inhuman of crimes? Can science in any way help us understand these horrific events and provide any clues as to how to prevent them in the future? As the nation tries to understand the tragic events at Newtown, NOVA correspondent Miles O’Brien separates fact from fiction, investigating new theories that the most destructive rampage killers are driven most of all, not by the urge to kill, but the wish to die. Could suicide–and the desire to go out in a media-fueled blaze of glory–be the main motivation? How much can science tell us about the violent brain? Most importantly, can we recognize dangerous minds in time—and stop the next Newtown?

Épisode 9 - Australia's First 4 Billion Years - Awakening

10 avril 2013

What can Australia reveal about how Earth was born and how life took hold? Join NOVA and host Dr. Richard Smith as they journey back to the very beginning of the Australian story in "Awakening." The first stop is Western Australia, around four and a half billion years ago, where we encounter an Earth shortly after its fiery birth. Hidden in the red hills of Australia are clues to the mysteries of when the Earth was born, how life first arose, and how it transformed the planet. Experts unveil how the earliest forms of life—an odd assortment of bacterial slime—flooded the atmosphere with oxygen, sparking the biological revolution that made animal life possible. It is the beginning of the great drama of life on Earth.

Épisode 10 - Australia's First 4 Billion Years - Life Explodes

17 avril 2013

How did life storm the beaches and dominate planet Earth? Ancient Australian fossils offer clues in "Life Explodes." Half a billion years ago, Australia was still part of the super-continent Gondwana. The oceans were teeming with weird and wonderful animals, but the world above the waves remained an almost lifeless wasteland. All that was about to change, though. Host Richard Smith introduces Earth's forgotten pioneers: the scuttling arthropod armies that invaded the shores and the waves of green revolutionaries whose battle for the light pushed plant life across the face of a barren continent. Evolution continued underwater as well, with armor-plated fish experimenting with teeth, jaws, sex, and lungs. NOVA's prehistoric adventure continues with four-legged animals walking onto dry land—and the planet poised for disaster.

Épisode 11 - Australia's First 4 Billion Years - Monsters

24 avril 2013

"Monsters" begins Down Under at the dawn of the Age of Dinosaurs. Host Richard Smith comes face-to-face with the previously unknown reptilian rulers of prehistoric Australia. NOVA resurrects the giants that stalked the Great Southern Land and discovers that some of these animals were among the largest ever to have walked the Earth. Others were some of the most dangerous. In the dry desert heart, scientists unearth an ancient inland ocean full of sea monsters. Opal fossils of some of these beasts paint a colorful picture of the exotic seascape, where long-necked plesiosaurs snacked on shelled creatures that grew as large as truck tires. The most fearsome was Kronosaurus, with a skull twice as long as T. rex. But reptiles didn't have the world all to themselves. Mammals like the enigmatic platypus lived alongside them, ready for their moment in the sun.

Épisode 12 - Australia's First 4 Billion Years - Strange Creatures

1 mai 2013

In the wake of the catastrophic asteroid impact believed to have wiped out the dinosaurs, Australia was set adrift on a lonely voyage across southern seas. With host Richard Smith, NOVA travels the walkabout continent to uncover how it became the strange land it is today. In this final episode, "Strange Creatures," NOVA traces the last 65 million years, revealing the events that shaped the Australia we know today. Prehistoric jungles retreated, replaced by eucalypt forests, grasslands, and deserts. When humans first arrived, giant marsupials dominated the land and the Great Barrier Reef was yet to form. This is a tale of calamity and conquest; how a conspiracy of climate, biology, and geology shaped the Earth we now call home.

Épisode 13 - Meteor Strike

Épisode 15 - Oklahoma's Deadliest Tornadoes

29 mai 2013

On May 20, 2013, a ferocious EF5 tornado over a mile wide tore through Moore, Oklahoma, inflicting 24 deaths and obliterating entire neighborhoods. It was the third time an exceptionally violent tornado had struck the city in 14 years. Yet predicting when and where these killer storms will hit still poses a huge challenge. Why was 2011—the worst ever recorded tornado season that left 158 dead in Joplin, Missouri—followed by the quietest ever year of activity prior to the Moore disaster? Can improved radar and warning technology explain why so many fewer died in Moore than in Joplin? And will tornadoes get worse as Earth's climate heats up? In this NOVA special, we meet scientists in the front ranks of the battle to understand these extreme weather events. We also meet storm survivors whose lives have been upended and learn how we can protect ourselves and our communities for the uncertain future.

Épisode 22 - Cold Case JFK

13 novembre 2013

For decades, the assassination of John F. Kennedy has fueled dark rumors of conspiracies and mishandled evidence. Now, fifty years later, NOVA asks: Could modern investigators do better? We’ll see how state-of-the art forensic tools would be applied to the investigation were it to happen today. At the same time, NOVA takes a critical look at contemporary cases, like the murders of Nicole Brown Simpson and Ronald Goldman, to reveal how charges of evidence mishandling and human error can mar even scientifically sophisticated detective work. Will forensics ever be truly foolproof, or does modern technology just give a scientific sheen to a practice that will always be more art than science?

Épisode 23 - At the Edge of Space

20 novembre 2013

Between the blue sky above and the infinite blackness beyond lies a frontier that scientists have only just begun to investigate. In "At the Edge of Space," NOVA takes viewers on a spectacular exploration of the Earth-space boundary that's home to some of nature's most puzzling and alluring phenomena: the shimmering aurora, streaking meteors, and fleeting flashes that shoot upwards from thunderclouds, known as sprites. Only discovered in 1989, sprites have eluded capture because they exist for a mere split-second—40-times faster than an eye blink. NOVA rides with scientists in a high-flying weather observation plane on a hunt for sprites, finally snaring them in 3D video and gaining vital clues to unraveling their mystery. Combining advanced video technology with stunning footage shot from the International Space Station, "At the Edge of Space" probes the boundary zone and offers an entirely new perspective on our home planet.

Épisode 24 - Asteroid: Doomsday or Payday?

20 novembre 2013

The asteroid that exploded over Siberia—injuring more than 1,000 and damaging buildings in six cities—was a shocking reminder that Earth is a target in a cosmic shooting range. From the width of a football field to the size of a small city, these space rocks have the potential to be killers. In a collision with Earth, they could set off deadly blast waves, raging fires and colossal tidal waves. But some audacious entrepreneurs look up at asteroids and see payday, not doomsday. Some asteroids are loaded with billions of dollars’ worth of elements like iron, nickel, and platinum. NASA is planning an ambitious mission to return samples from a potentially hazardous asteroid, and would-be asteroid miners are dreaming up their own program to scout for potentially profitable asteroids. Will asteroids turn out to be our economic salvation—or instruments of extinction?

Épisode 2 - Zeppelin Terror Attack

15 janvier 2014

Londres brûle. Les bombes allemandes déciment foyers britanniques et le mensonge morts en tas. Mais ce Blitz n'a rien à voir avec la Seconde Guerre mondiale. Cette histoire peu connue d'une campagne de terreur de bombardements sur la capitale a eu lieu au cours de la Première Guerre mondiale. Pendant 18 mois, le carnage a été livré par une machine directement à partir des pages de science-fiction. Le Zeppelin, la plus grande machine de vol qui ait jamais existé, a livré une charge mortelle droit au cœur d'une nation et, pour une fois, il n'y avait rien que les Britanniques puissent faire pour les arrêter. Ce nouveau type de campagne de terreur a réécrit les règles de la guerre. Pour la première fois dans l'histoire, des civils innocents ont été bombardés dans leurs maisons, dans une tentative impitoyable pour briser le moral d'une nation. La première campagne de bombardements aériens de l'histoire est aussi l'histoire de la course aux armements d'ingénierie entre l'Allemagne et la Grande-Bretagne. Ingénieur Dr Hugh Hunt étudie les défis techniques que chaque partie a dû surmonter dans leur guerre dans l'air. La plupart des détails sur ce qui est arrivé il ya un siècle a été perdu à l'histoire, il ya donc beaucoup de mystères d'ingénierie exceptionnelles sur l'histoire Zeppelin pour Hugh pour obtenir ses dents dans: mystères qui ne peuvent être résolus par faire des expériences pratiques. Il tente de savoir pourquoi il était si difficile pour les armes britanniques à faire baisser Zeppelins: un problème de surprenant étant donné que les dirigeables ont été remplis avec de l'hydrogène gazeux inflammable. Il teste véritable Première Guerre mondiale munitions Zepp-busting et reverse engineering bombes Première Guerre mondiale pour savoir exactement comment ces technologies ont travaillé. Le matériau qui a tenu le gaz dans un Zeppelin a été faite de vache intestin, si Hugh exécute une sé

Épisode 3 - Ghosts of Murdered Kings

29 janvier 2014

In the rolling hills of Ireland's County Tipperary, a laborer harvesting peat from a dried-up bog spots the remnants of a corpse and stops his machine just in time, revealing a headless torso almost perfectly preserved and stained dark brown by the bog. Archeologists recognize the corpse as one of Europe's rare bog bodies: prehistoric corpses flung into marshes with forensic clues often suggesting execution or human sacrifice. The corpse will eventually be dated to the Bronze Age, over 3,000 years ago. Many of these were victims of shocking violence, showing evidence of axe blows, hanging, and stab wounds. Like a crime thriller, NOVA follows archaeologists and forensic experts in their methodical hunt for clues to the identity and the circumstances of this and other violent deaths of bog body victims. A new theory emerges that they are those of ritually murdered kings, gruesomely slain to assure the fertility of land and people. NOVA’s ancient detective story opens a tantalizing window on the strange beliefs of Europe's long vanished prehistoric peoples.

Épisode 4 - Roman Catacomb Mystery

5 février 2014

Beneath the streets of Rome lies a city of the dead known as the Catacombs—a labyrinth of tunnels, hundreds of miles long, lined with the neatly laid out tombs of the citizens of ancient Rome. Here, in 2002, maintenance workers fixing a broken water main stumbled upon a previously unknown burial chamber like none other in the complex. It was a mass grave of hundreds of bodies spread across six roughly carved caverns, locked away for nearly 2000 years. Who were these people? And can we discover, after all these centuries, what killed them? Could they be Christian martyrs massacred by the Emperor? Or were they felled by a deadly plague? In “Roman Catacomb Mystery,” NOVA’s forensic investigation follows a trail of ancient clues to uncover new secrets of life, death, and disease in the heyday of a mighty empire.

Épisode 5 - Great Cathedral Mystery

12 février 2014

The dome that crowns Florence’s great cathedral of Santa Maria del Fiore—the Duomo—is a towering masterpiece of Renaissance ingenuity and an enduring source of mystery. Still the largest masonry dome on earth after more than six centuries, it is taller than the Statue of Liberty and weighs as much as an average cruise ship. Historians and engineers have long debated how its secretive architect, Filippo Brunelleschi, managed to keep the dome perfectly aligned and symmetrical as the sides rose and converged toward the center, 40 stories above the cathedral floor. His laborers toiled without scaffolding or safety net, applying novel, untried methods. Over 4 million bricks might collapse at any moment—and we still don’t understand how Brunelleschi prevented it. To test the latest theories, a team of U.S. master bricklayers will help build a unique experimental model Duomo using period tools and techniques. Will it stay intact during the final precarious stages of closing over the top of the dome?

Épisode 6 - Killer Typhoon

22 janvier 2014

It was the strongest cyclone to hit land in recorded history. On November 8, 2013, Typhoon Haiyan slammed into the Philippines, whipping the low-lying and densely-populated islands with 200 mph winds and sending a two-story-high storm surge flooding into homes, schools, and hospitals. It wiped villages off the map and devastated cities, including the hard-hit provincial capital Tacloban. Estimates count more than 5,000 dead and millions homeless. What made Haiyan so destructive? Meteorologists charged with tracking Pacific storms reveal why the Pacific is such fertile ground for cyclones, and NOVA’s film crew documents how conditions dramatically deteriorated in the storm’s aftermath, as impassable roads and shuttered gas stations paralyzed the critical relief effort, leaving food, water, and medicine to pile up at the airport. Disaster preparedness experts scramble to understand why the Philippines was so vulnerable. As climate change and sea level rise threaten millions of the world’s most impoverished people with stronger, and perhaps more frequent, storms, how can we prepare for the next monster typhoon?

Épisode 7 - Wild Predator Invasion

2 avril 2014

Over the last few centuries we have shot, trapped, and skinned the predators that formerly thrived at the top of the food chain in the wild. Wild bears, wolves, and big cats are all in retreat, and a growing number of scientists are discovering that by eliminating predators, we have changed the environment. Removing predators from the wild has thrown ecosystems off-kilter, triggering domino effects that scientists are just beginning to understand. In "Wild Predator Invasion," NOVA follows scientists who are trying a simple but controversial solution: returning apex predators—like wolves, bears, and panthers—to their natural environments. Can these newly reintroduced predators restore the natural balance of their ecosystems without threatening the humans who live among them?

Épisode 8 - Inside Animal Minds: Bird Genius (1)

9 avril 2014

Inside Animal Minds explores how animals understand the world around them through the eyes of three iconic creatures: dogs, birds, and dolphins. As we discover how scientists are pushing the animal mind to its limits, we’ll uncover surprising similarities to--and differences from--the human mind. In the first installment, “Bird Genius”, we’ll meet a cockatoo with a talent for picking locks; a wild crow on a mission to solve an eight-step puzzle; and a tame raven who can solve a puzzle box so quickly that his performance has to be captured with high-speed photography. Are these skills really evidence of high intelligence or just parlor tricks, the result of training and instinct?

Épisode 9 - Inside Animal Minds: Dogs & Super Senses (2)

16 avril 2014

On Inside Animal Minds’ second installment, “Dogs & Super Senses”, see everything from a dog that seems to use smell to tell time to a dolphin that can “see” with its ears, discover how animals use their senses in ways we humans can barely imagine. But it’s not just the senses that are remarkable -- it’s the brains that process them.

Épisode 10 - Inside Animal Minds: Who’s the Smartest? (3)

23 avril 2014

On Inside Animal Minds’ third and final installment, “Who’s the Smartest?”, we ask “What makes an animal smart?”. Many scientists believe the secret lies in relationships. Throughout the animal kingdom, some of the cleverest creatures — including humans — seem to be those who live in complex social groups, like dolphins, elephants and apes. Could the skills required to keep track of friend and foe make animals smarter? To find out, NOVA goes inside the social lives of some of the smartest animals on the planet.

Épisode 11 - Why Sharks Attack

7 mai 2014

In recent years, an unusual spate of deadly shark attacks has gripped Australia, resulting in five deaths in ten months. At the same time, great white sharks have begun appearing in growing numbers off the beaches of Cape Cod, Massachusetts, not far from the waters where Steven Spielberg filmed the ultimate shark fright film, Jaws. What's behind the mysterious arrival of this apex predator in an area where they've rarely been seen for hundreds of years? Are deadly encounters with tourists inevitable? To separate fact from fear, NOVA teams up with leading shark experts in Australia and the United States to discover the science behind the great white's hunting instincts. Do sharks ever target humans, or is each attack a tragic case of mistaken identity? And can a deeper understanding of shark senses lead scientists to design effective deterrents and help prevent future attacks?

Épisode 12 - Escape From Nazi Alcatraz

14 mai 2014

Colditz Castle, a notorious prisoner of war camp in Nazi Germany, was supposed to be escape-proof. But in the dark days at the end of World War II, a group of British officers dreamt up the ultimate escape plan: in a secret attic workshop, they constructed a two-man glider out of bed sheets and floorboards. Their plan was to fly to freedom from the roof of the castle, but the war ended before they could put it to the test. Now a crack team of aero engineers and carpenters rebuild the glider in the same attic using the same materials, and they’ll do something the prisoners never got a chance to try: use a bathtub full of concrete to catapult the glider off the roof of the castle. As the hair-raising launch 90 feet up draws near, the program explores the Colditz legend and exposes the secrets of other ingenious and audacious escapes. Then, after a 70-year wait, the team finally finds out if the legendary glider plan would have succeeded.

Épisode 13 - D-Day's Sunken Secrets

28 mai 2014

On June 6, 1944, the Allies launched the biggest armada in history to invade the Normandy beaches and liberate Europe from the Nazis. In less than 24 hours, more than 5,000 ships crossed the English Channel, along with thousands of tanks and landing craft and nearly 200,000 men. Throughout the operation, hundreds of ships sank running the gauntlet of mines and bunkers, creating one of the world's largest underwater archaeological sites. Now, NOVA has exclusive access to a unique collaboration between military historians, archaeologists, and specialist divers to carry out the most extensive survey ever done of the seabed bordering the legendary beachheads. Dive teams, submersibles, and underwater robots will discover and identify key examples of Allied craft that fell victim to German shellfire, mines, and torpedoes, using the latest 3D-mapping tools to plot the relics on the sea floor. Highlighting the ingenious technology that helped the Allies overcome the German defenses, and featuring first-hand accounts from Allied veterans who have returned to the site of this epic battle to share their harrowing stories, "D-Day's Sunken Secrets" unfolds a vivid blow-by-blow account of the tumultuous events of D-Day and reveals how the Allies' intricate planning and advanced technology assured the success of the most ambitious and risky military operation ever launched.

Épisode 16 - Why Planes Vanish

8 octobre 2014

The disappearance of Flight MH370 stunned the world. In an era of smart-phones and GPS, how could a 270-ton passenger jet vanish into thin air? It was a rude awakening for all of us, showing just how far we are from the world we imagined we lived in—in which every move is monitored all the time. NOVA tells the inside story of the search for Flight MH370 and meets the key players from all corners of the globe who have spent months searching for the lost plane. In the search for answers, we'll reveal how today's planes must fly through vast radar "blind spots," and investigate new technologies that could allow ground stations and satellites to track planes automatically, without pilot intervention, even in remote areas with no radar coverage. What will it take to guarantee that in the future, nothing will ever be 'lost' again?

Épisode 17 - Surviving Ebola

8 octobre 2014

In December, 2013, in a small village in West Africa, a young boy died from the dreaded disease, Ebola. Over the next nine months the virulent killer would claim more victims than all previous Ebola epidemics put together. And for the first time, the disease escaped the isolated, rural villages where it had first appeared and traveled in infected patients by air to densely populated cities in several African countries. As the epidemic threatens to spiral out of control, NOVA reports from the hot zone, where courageous medical teams struggle to cope with a flood of victims, and in labs where scientists are racing to test vaccines and find a cure. "Surviving Ebola" includes chilling first-hand interviews of what it’s like to catch—and—survive this terrible affliction.

Épisode 18 - Ben Franklin's Balloons

22 octobre 2014

The first stage in human flight didn’t begin with the Wright brothers at Kitty Hawk, but with daring inventors and aeronauts in 18th century Paris. In a period of just 19 months, humanity not only left the ground for the first time—a moment as significant as the Apollo moon landing—but thanks to a handful of brilliant and colorful pioneers, developed all the essential features of today's hot air and gas balloons. Their exploits fascinated Benjamin Franklin, who was serving in Paris as the American ambassador. He reported that these early flights brought tens of thousands of citizens into the streets to watch the spectacle. To explore this burst of innovation, NOVA recreates key flights, including the world’s first manned voyage that took place on November 21, 1783. Joining the team will be a descendant of the Montgolfier brothers, inventors of the hot-air balloon, who will build an accurate replica of the fragile paper and canvas craft using 18th century tools and materials. NOVA reveals the secrets of how the Montgolfiers invented flight and relives the experiences of the balloon pioneers who left Earth for the first time.

Épisode 19 - First Air War

29 octobre 2014

When World War I began in 1914, the air forces of the opposing nations consisted of handfuls of rickety biplanes from which pilots occasionally took pot shots at one another with rifles. By the war’s end, the essential blueprint of the modern fighter had emerged: it was now an efficient killing machine that limited the average life expectancy of a front line pilot to just a few weeks. To trace the story of this astonishingly rapid technological revolution, NOVA takes viewers inside The Vintage Aviator, a New Zealand-based outfit of aviation buffs dedicated to bringing back classic World War I fighters such as the SE5A and Albatros DV. NOVA joins the team as they discover the secrets of some of aviation’s most colorful and deadly early flying machines and explores how their impact played a key role in the nightmare slaughter on the Western Front.

Épisode 20 - Bigger Than T. Rex

5 novembre 2014

Almost a century ago, paleontologists found the first tantalizing hints of a monster even bigger than Tyrannosaurus rex, perhaps the largest predator ever to roam the Earth: spectacular fossil bones from a dinosaur dubbed Spinosaurus. But the fossils were completely destroyed during a World War II Allied bombing raid, leaving only drawings, questions, and a mystery: What was Spinosaurus? Now, the discovery of new bones in a Moroccan cliff face is reopening the investigation into this epic beast. What did it feed on and how? Why did it grow so big? We follow the paleontologists who are reconstructing this terrifying carnivore, revealing a 53-foot-long behemoth with a huge dorsal sail, enormous, scimitar-like claws, and massive jaws tapered toward the front like a crocodile. Bringing together experts in paleontology, geology, climatology and paleobotany, this NOVA/National Geographic special brings to life the lost world over which Spinosaurus reigned more than 65 million years ago.

Épisode 21 - Emperor’s Ghost Army

12 novembre 2014

In central China, a vast underground mausoleum conceals a life-size terracotta army of cavalry, infantry, horses, chariots, weapons, administrators, acrobats, and musicians, all built to serve China's first emperor, Qin Shi Huang Di, in the afterlife. Lost and forgotten for over 2,200 years, this clay army, 8,000-strong, stands poised to help the First Emperor rule again beyond the grave. Now, a new archaeological campaign is probing the thousands of figures entombed in the mausoleum. With exclusive access to pioneering research, "Emperor's Ghost Army" reveals how the Emperor directed the manufacture of the tens of thousands of bronze weapons carried by the clay soldiers. NOVA tests the power of these weapons with high-action experiments and reports on revolutionary 3D computer modeling techniques that are revealing new insights into how the clay figures were made, revealing in the process the secrets of one of archaeology's greatest discoveries.

Épisode 22 - Killer Landslides

19 novembre 2014

Just before 11 a.m. on March 22, 2014, an ominous rumble startled the residents of the little town of Oso, Washington, about an hour’s drive from Seattle. It was the terrifying sound of the United States’ deadliest landslide in decades. In less than two minutes, a 250 acre field of debris 20 feet deep slammed into a neighborhood of 35 homes. In the wake of the tragedy, geomorphologists are tracing the geological history of Oso to explain why the site was so unstable. But Oso isn't alone. Globally, landslides and other ground failures cost more lives and money each year than all other natural disasters combined. The threat of bigger, more frequent landslides is growing as climate change increases intense precipitation events. As NOVA follows scientists surveying landslide danger zones, discover how and why landslides happen and how new laser monitoring technologies may help predict landslides before disaster strikes.

Épisode 4 - Colosseum: Roman Death Trap

11 février 2015

One of the ancient world's most iconic buildings, the Colosseum is a monument to Roman imperial power and cruelty. Its graceful lines and harmonious proportions concealed a highly efficient design and advanced construction methods that made hundreds of arches out of 100,000 tons of stone. In its elliptical arena, tens of thousands of gladiators, slaves, prisoners, and wild animals met their deaths. Ancient texts report lions and elephants emerging from beneath the floor, as if by magic, to ravage gladiators and people condemned to death. Then, just as quickly, the Colosseum could be flooded with so much water that ships could engage in sea battles to the delight of the crowd. Now, archaeologists and engineers are teaming up to recreate a 25-foot lifting machine and trap door system capable of releasing a wolf into the Colosseum's arena for the first time in 1,500 years. Do they have what it takes to replicate the innovation and ingenuity of the Romans?

Épisode 5 - Petra: Lost City of Stone

18 février 2015

More than 2,000 years ago, the thriving city of Petra rose up in the bone-dry desert of what is now Jordan. An oasis of culture and abundance, the city was built by wealthy merchants whose camel caravans transported incense and spices from the Arabian Gulf. They carved spectacular temple-tombs into its soaring cliffs, raised a monumental Great Temple at its heart, and devised an ingenious system that channeled water to vineyards, bathhouses, fountains, and pools. But following a catastrophic earthquake and a slump in its desert trade routes, Petra's unique culture faded and was lost to most of the world for nearly a thousand years. Now, in a daring experiment, an archaeologist and sculptors team up to carve an iconic temple-tomb to find out how the ancient people of Petra built their city of stone. Meanwhile, scientists using remote sensors and hydraulic flumes uncover the vast city and its sophisticated water system. The race is on to discover how these nomads created this oasis of culture in one of the harshest climates on Earth.

Épisode 6 - Hagia Sophia: Istanbul’s Ancient Mystery

25 février 2015

Épisode 1 - Secret Tunnel Warfare

6 janvier 2016

During World War I, the Allies and Germans repeatedly struggled to break the hideous stalemate of trench warfare. In the winter of 1916, Allied engineers devised a massive surprise attack: over 1 million pounds of explosives hidden in secret tunnels driven under German lines. Building the tunnels was desperate work, with tunnelers at constant risk from flooding, cave-ins, and enemy digging teams. In June of 1917, the planted mines at Messines were simultaneously triggered, killing an estimated 10,000 German troops instantly. Now, archaeologists are revealing the extraordinary scale and risks of the Allied tunneling operations in one of the biggest excavations ever undertaken on the Western Front. “Secret Tunnel Warfare” opens a unique window on the frenzy of Allied mining activity that led up to the attack and its bitter aftermath.

13 janvier 2016

Four and a half billion years ago, the young Earth was a hellish place—a seething chaos of meteorite impacts, volcanoes belching noxious gases, and lightning flashing through a thin, torrid atmosphere. Then, in a process that has puzzled scientists for decades, life emerged. But how? NOVA joins mineralogist Robert Hazen as he journeys around the globe. From an ancient Moroccan market to the Australian Outback, he advances a startling and counterintuitive idea—that the rocks beneath our feet were not only essential to jump-starting life, but that microbial life helped give birth to hundreds of minerals we know and depend on today. It's a theory of the co-evolution of Earth and life that is reshaping the grand-narrative of our planet’s story.

Épisode 3 - Mystery Beneath the Ice

20 janvier 2016

Tiny, transparent, and threatened, krill are crucial to the Antarctic ecosystem. But the population of krill is crashing for reasons that continue to baffle the experts. A leading theory says that krill’s life cycle is driven by an internal body clock that responds to the waxing and waning of the Antarctic ice pack, and as climate change alters the timing of the ice pack, their life cycle is disrupted. To test it, NOVA travels on the Polarstern, a state-of-the-art research vessel, to the frigid ice pack in the dead of winter. From camps established on the ice, scientists dive beneath the surface in search of the ice caves that shelter juvenile krill during the winter. There, they hope to discover what’s causing the krill to vanish and, ultimately, how the shifting seasons caused by climate change could disrupt ecosystems around the world.

Épisode 6 - Memory Hackers

10 février 2016

Memory is the glue that binds our mental lives. Without it, we’d be prisoners of the present, unable to use the lessons of the past to change our future. From our first kiss to where we put our keys, memory represents who we are and how we learn and navigate the world. But how does it work? Neuroscientists using cutting-edge techniques are exploring the precise molecular mechanisms of memory. By studying a range of individuals ranging—from an 11-year-old whiz-kid who remembers every detail of his life to a woman who had memories implanted—scientists have uncovered a provocative idea. For much of human history, memory has been seen as a tape recorder that faithfully registers information and replays intact. But now, researchers are discovering that memory is far more malleable, always being written and rewritten, not just by us but by others. We are discovering the precise mechanisms that can explain and even control our memories. The question is—are we ready?

One unlucky day 13,000 years ago, a slight, malnourished teenager missed her footing and tumbled to the bottom of a 100-foot pit deep inside a cave in Mexico’s Yucatán. Rising seas flooded the cave and cut it off from the outside world—until a team of divers chanced upon her nearly complete skeleton in 2007. Intricate detective work reveals that the young woman’s bones are among the earliest known human remains in the Americas. What drove her to venture nearly a mile underground inside a vast cave? Where did her people come from, and why does she look so distinct from today’s Native Americans? From a stunning Mexico cave to the wilderness of the Yukon, from the genetics lab to the forefront of forensics, NOVA pursues tantalizing new clues that are rewriting the story of the forgotten first people who ventured into our continent.

Épisode 4 - Great Escape at Dunkirk

14 février 2018

As France fell to the German armies in May 1940, 300,000 Allied troops were trapped on the beaches of Dunkirk. Their annihilation seemed certain - a disaster that could have led to Britain's surrender. But then, in a last-minute rescue dramatized in Christopher Nolan's recent film, Royal Navy ships and a flotilla of tiny civilian boats evacuated hundreds of thousands of soldiers to safety across the Channel - the legendary "miracle of Dunkirk." Now, NOVA follows a team of archaeologists, historians, and divers as they recover the remains of ships, planes, and personal effects lost during the epic operation. With access to previously classified files recently released by the UK government, they also uncover the truth behind the myths of Dunkirk - notably, a claim that the Royal Air Force failed to protect the stranded men from the Luftwaffe's constant bombing of the beaches. Featuring an exclusive excavation of a newly-found Spitfire wreck, NOVA debunks the myth and highlights the essential role that the RAF's iconic fighter played in reversing the desperate stakes that played out in the air above the beleaguered men.

28 février 2018

Predictions underlie nearly every aspect of our lives, from sports, politics, and medical decisions to the morning commute. With the explosion of digital technology, the internet, and “big data,” the science of forecasting is flourishing. But why do some predictions succeed spectacularly while others fail abysmally? And how can we find meaningful patterns amidst chaos and uncertainty? From the glitz of casinos and TV game shows to the life-and-death stakes of storm forecasts and the flaws of opinion polls that can swing an election, “Prediction by the Numbers” explores stories of statistics in action. Yet advances in machine learning and big data models that increasingly rule our lives are also posing big, disturbing questions. How much should we trust predictions made by algorithms when we don’t understand how they arrive at them? And how far ahead can we really forecast?

Épisode 6 - Decoding the Weather Machine

18 avril 2018

Disastrous hurricanes. Widespread droughts and wildfires. Withering heat. Extreme rainfall. It is hard not to conclude that something’s up with the weather, and many scientists agree.
