NOVA: Episode 2
Tóm tắt
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.

The Vikings were among the fiercest warriors of all time. Yet only a select few carried the ultimate weapon of their era: the feared Ulfberht sword. Fashioned using a process that would remain unknown to the Vikings’ rivals for centuries, the Ulfberht was a revolutionary high-tech tool as well as a work of art. Considered one of the greatest swords ever made, it remains a fearsome weapon more than a millennium after it last saw battle. But how did Viking sword makers design and build the Ulfberht, and what was its role in history? Now, NOVA uses cutting edge science and old-fashioned detective work to reconstruct the Ulfberht and finally unravel the "Secrets of the Viking Sword."

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.

Why go back to Mars? Far from dead, Mars holds untold potential. Nearly half a century of Mars exploration has yielded tantalizing clues that Mars may once have harbored life—and may harbor it still. The extraordinary landing of a revolutionary rover named Curiosity—which successfully touched down inside the Gale Crater—means we have wheels down on the planet once again, in the form of the most sophisticated robot ever to rove the Mars surface. Will NASA's bold mission and this marvel of technology answer some of our biggest questions and usher in a new golden age of exploration? NOVA goes behind the scenes on NASA’s quest to solve the riddles of the red planet.

In April, 2010 the eruption of Iceland's Eyjafjallajökull volcano turned much of Europe into an ash-strewn no-fly zone, stranding millions of travelers. But was Eyjafjallajökull just the start? Now, an even more threatening Icelandic volcano, Katla, has begun to swell and grumble. Two more giants, Hekla and Laki, could erupt without warning. Iceland is a ticking time bomb: When it blows, the consequences could be global. As CGI takes us inside these geological monsters, we meet atmospheric scientists who are working to understand just how devastating an eruption could be—not just for air travel but for the global food supply and for Earth's climate.

Drones. These unmanned flying robots–some as large as jumbo jets, others as small as birds–do things straight out of science fiction. Much of what it takes to get these robotic airplanes to fly, sense, and kill has remained secret. But now, with rare access to drone engineers and those who fly them for the U.S. military, NOVA reveals the amazing technologies that make drones so powerful as we see how a remotely-piloted drone strike looks and feels from inside the command center. From cameras that can capture every detail of an entire city at a glance to swarming robots that can make decisions on their own to giant air frames that can stay aloft for days on end, drones are changing our relationship to war, surveillance, and each other. And it's just the beginning. Discover the cutting edge technologies that are propelling us toward a new chapter in aviation history as NOVA gets ready for "Rise of the Drones.
Tập 9
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.
Tập 10
3,600-year-old reliefs in Egyptian tombs and temples depict pharaohs and warriors proudly riding into battle on horse-drawn chariots. Some historians claim that the chariot launched a technological and strategic revolution, and was the secret weapon behind Egypt's greatest era of conquest known as the New Kingdom. But was the Egyptian chariot really a revolutionary design? How decisive a role did it play in the bloody battles of the ancient world? In "Building Pharaoh's Chariot," a team of archaeologists, engineers, woodworkers, and horse trainers join forces to build and test two highly accurate replicas of Egyptian royal chariots. They discover astonishingly advanced features, including spoked wheels, springs, shock absorbers, anti-roll bars, and even a convex-shaped rear mirror, leading one of them to compare the level of design to the engineering standards of 1930's-era Buicks! By driving our pair of replicas to their limits in the desert outside Cairo, NOVA's experts test the claim that the chariot marks a crucial turning point in ancient military history.

"Earth From Space" is a groundbreaking two-hour special that reveals a spectacular new space-based vision of our planet. Produced in extensive consultation with NASA scientists, NOVA takes data from earth-observing satellites and transforms it into dazzling visual sequences, each one exposing the intricate and surprising web of forces that sustains life on earth. Viewers witness how dust blown from the Sahara fertilizes the Amazon; how a vast submarine "waterfall" off Antarctica helps drive ocean currents around the world; and how the sun's heating up of the southern Atlantic gives birth to a colossally powerful hurricane. From the microscopic world of water molecules vaporizing over the ocean to the magnetic field that is bigger than Earth itself, the show reveals the astonishing beauty and complexity of our dynamic planet.

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?
