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?

  • S26E02 Submarines, Secrets & Spies

    • January 19, 1999
    • PBS

    At the height of the Cold War, US subs gathered secrets that neither spies nor satellites could expose. Until recently, almost nobody knew the hidden history of their tragedies and triumphs. As the US strove for supremacy in the Cold War, it pushed submarine technology to its limits. Breakthroughs led to unparalleled triumphs of espionage. And, missteps cost hundreds their lives. With recently declassified film, NOVA lifts the veil on tragic and mysterious submarine accidents and their high-risk spy missions that helped win the Cold War. Along with celebrated oceanographer and explorer, Robert Ballard (discoverer of the Titanic), NOVA goes in search of clues to two tragedies of the Cold War, the wrecks of the nuclear submarines Thresher and Scorpion. Recently declassified footage gives a unique glimpse of the wrecks and a chance to investigate the catastrophic accidents that overtook these subs and their crew.

  • S26E03 Surviving AIDS

    • February 2, 1999
    • PBS

    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.

  • S26E11 Time Travel

    • October 12, 1999
    • PBS

    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.

  • S26E12 The Killer's Trail

    • October 19, 1999
    • PBS

    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.

  • S26E13 Island of the Spirits

    • November 2, 1999
    • PBS

    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.

  • S26E14 Decoding Nazi Secrets

    • November 9, 1999
    • PBS

    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.

  • S26E15 Voyage Of Doom

    • November 23, 1999
    • PBS

    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.

    In 1996, near Kennewick, Washington, a suspected murder victim is identified by forensic anthropologists as Caucasian - but turns out to be almost 10,000 years old. For fifty years our picture of prehistoric America has rested on the premise that the earliest inhabitants of the Americas were east Asians of mongoloid stock, the ancestors of today's Native Americans. But the discovery of the Kennewick Man, along with several other startling finds in recent years, has thrown that once widely accepted idea into question and revolutionized the science of paleo-anthropology. It has also embroiled scientists in a bitter conflict with Native American groups who want the scientific study of early Americans halted. Who and what do Kennewick Man and others represent?

  • S30E09 Secret Of Photo 51

    • April 15, 2003
    • PBS

    On April 25, 1953, James Watson and Francis Crick published their groundbreaking discovery of the double helix structure of DNA, the molecule essential for passing on our genes and the ''secret of 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.

  • S32E01 Welcome To Mars

    • January 4, 2005
    • PBS

    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

    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.

    • November 22, 2005
    • PBS

    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

  • S34E13 Judgment Day: Intelligent Design On Trial

    • November 13, 2007
    • PBS

    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

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.

    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.

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.”

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.

  • S41E05 Great Cathedral Mystery

    • February 12, 2014
    • PBS

    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?

  • S41E06 Killer Typhoon

    • January 6, 2016
    • PBS

    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.

    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.

    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?
