  • #3808 — Venom: Nature's Killer
    Venom scientists are in a race against time. Inside the bodies of many creatures, evolution has produced extreme toxic cocktails, all designed for one reason: to kill. It took millions of years to perfect these ultimate brews of proteins and peptides and we have only just begun to discover their potential. Now, the race is on to collect and study them before the animals that produce them disappear. But how does venom do its deadly work? NOVA reveals how venom causes the body to shut down, arteries to bleed uncontrollably and limbs to go black and die. But nature's most destructive and extreme poisons could contain the building blocks for a new generation of advanced drugs that could treat heart attack, stroke, diabetes, obesity and cancer. VENOM follows scientists on their expeditions to track down and capture the planet's most deadly creatures, risking life and limb just to tease out milligrams of venom and get it back to the lab. Find out how nature's deadliest cocktails could be medicine's brightest new hope.

  • #3810 — Japan's Killer Quake
    In its worst crisis since World War II, Japan faces disaster on an epic scale: a rising death toll in the tens of thousands, massive destruction of homes and businesses, shortages of water and power, and the specter of nuclear reactor meltdowns. The facts and figures are astonishing. The March 11th earthquake was the world's fourth largest earthquake since record keeping began in 1900 and the worst ever to shake Japan. The seismic shock wave released over 4,000 times the energy of the largest nuclear test ever conducted; it shifted the earth's axis by 6 inches and shortened the day by a few millionths of a second. The tsunami slammed Japan's coast with 30 feet-high waves that traveled 6 miles inland, obliterating entire towns in a matter of minutes. JAPAN'S KILLER QUAKE combines authoritative on-the-spot reporting, personal stories of tragedy and survival, compelling eyewitness videos, explanatory graphics and exclusive helicopter footage for a unique look at the science behind the catastrophe.

  • #3903 — 3d Spies of WWII
    During World War II, Hitler's scientists developed terrifying new weapons of mass destruction. Alarmed by rumors about 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 were 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 Hitler.

  • #4113 — D-Day's Sunken Secrets
    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 discover and identify key examples of the Allied craft that fell victim to German shellfire, mines and torpedoes. The team uses 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, "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 was vital to assure the success of the most ambitious and risky military operation ever launched.

  • #4121 — Killer Landslides
    In less than two minutes in March, a one-square-mile field of debris slammed into the Washington state community of Oso, killing 41 and destroying nearly 50 homes. Drawing on analysis of other recent landslides around the world, geologists are investigating what triggered the deadliest U.S. landslide in decades and whether climate change is increasing the risk of similar disasters around the globe.
