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.

Vaccines - Calling the Shots, a new NOVA special, takes viewers around the world to track epidemics, explore the science behind vaccinations, and shed light on the risks of opting out. The vast majority of Americans vaccinate their children, and most do it on the recommended schedule. Yet many people have questions about the safety of vaccines, and in some communities, vaccination rates have fallen below the level needed to maintain "herd immunity" --allowing outbreaks to take hold and spread. This film draws on the latest, best available evidence to help parents find the answers.

From PBS - 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 ninety 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.

From PBS - The dome that crowns Florence's great cathedral of Santa Maria del Fiore -- the Duomo -- is a masterpiece of Renaissance ingenuity and an enduring source of mystery. Still the largest masonry dome on earth, 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 architect, Filippo Brunelleschi, kept the dome perfectly aligned and symmetrical as the sides rose and converged toward the center. More than four million bricks could collapse at any moment -- and we still don't understand how Brunelleschi prevented it. To test the latest theories, a team of U.S. bricklayers will help build an experimental "mini-Duomo" using period tools and techniques.

In 2002, maintenance workers stumbled through an opening in one of the tunnel walls and discovered a previously unknown complex of six small rooms, each stacked floor to ceiling with skeletons. It was a mass grave, locked away for nearly 2,000 years. Who were these people? Why were so many interred in one place, piled atop each other? And most important, what killed them?

On November 8, 2013, Typhoon Haiyan -- what some are calling "the perfect storm" -- slammed into the Philippines, whipping the low-lying and densely-populated islands with 200 mile-per-hour 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? In-depth interviews with the meteorologists charged with tracking and forecasting Pacific storms take us inside the anatomy of the typhoon, tracking its progress from its start as a low-pressure area over Micronesia to its deadly landfall and revealing why the Pacific is such fertile ground for cyclones. But that's just part of the story of why this storm was so deadly.

But the aircraft delivering the lethal payloads weren't planes. They were Zeppelins, enormous airships, some the length of two football fields. With a team of engineers, explosives experts, and historians, NOVA investigates the secrets behind these deadly war machines. Zeppelin Terror Attack explores the technological arms race that unfolded as Britain desperately scrambled to develop defenses that could neutralize the threat, while Germany responded with ever bigger and more powerful Zeppelins. Why were these German monsters of the sky, filled with highly flammable hydrogen gas, so difficult to shoot down? How were their massive gas bags pieced together from the intestines of millions of cows? Experts reconstruct and detonate deadly WWI incendiary bombs and test fire antique flaming bullets, all to discover how the British came up with the unique artillery that would finally take down the biggest flying machines ever made.

From PBS and NOVA: Cold Case JFK. 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?

From PBS and NOVA: Is it possible to engineer an absolutely safe world for ourselves? Host David Pogue explores the extent to which science and technology can protect us from monumental forces of nature such as earthquakes and epidemics. He challenges researchers to save us from dangers of our own making, such as traffic accidents and contact sports. Our increasing reliance on the internet makes us vulnerable to new risks: Pogue delves into cyber security, where computer experts work to shield us from attacks from hackers and terrorists. Risk is all around us -- but we can be smart about it.

From PBS and NOVA: What happens when engineers open up nature's toolbox? David Pogue explores bold innovations inspired by the Earth's greatest inventor, life itself. From underwater wi-fi based on dolphin communication, to robotic "mules" and "cheetahs" for the military, to swarms of robotic bees, Pogue travels the world seeing the "wildest" ideas put into action in new inventions and technologies. It is a journey that sees today's bacteria turned into tomorrow's metallurgists, viruses building batteries, and even DNA, the Code of Life, put to work in "living" computers. Will the stuff of the future take on a life of its own?

The arms and faces of ancient statuary litter the seabed at the site of a shipwreck off the coast of Greece. But that's not the most interesting find. Encrusted with over 2,000 years of mineral deposits are highly engineered gears clearly visible as part of a mysterious device dating back to about 50 BCE. Using X-ray technology and working off of the realization that the gears' teeth are prime numbers relating to astronomy, the device is revealed to be the earliest known computer used for predicting eclipses and demonstrating planetary motion.

Dinosaurs are generally considered tropical animals. So what are their fossils doing north of the arctic circle? Paleontologists battle the fierce climate to find out if the arctic was warmer then than it is now, or the arctic was farther from the North Pole, or the dinosaurs were migratory animals, or if they warm blooded.
