Diseases that were largely eradicated in the United States a generation ago — whooping cough, measles, mumps — are returning, in part because nervous parents are skipping their children's shots. "Vaccines – Calling the Shots" takes viewers around the world to track epidemics, explore the science behind vaccinations and shed light on the risks of opting out. The program features scientists, pediatricians, psychologists, anthropologists and parents wrestling with vaccine-related questions.
Our lives are going digital. We shop, bank and even date online. Computers hold our treasured photographs, private emails, and all of our personal information. This data is precious -- and cybercriminals want it. Now, NOVA goes behind the scenes of the fast-paced world of cryptography to meet the scientists battling to keep our data safe.
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. How easy is it to make a plane disappear? Or can new technology guarantee that in the future, nothing will ever be "lost" again?
As the Ebola 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, to 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 contract — and survive — this terrible affliction.
NOVA re-creates key flights, including the world’s first manned voyage on November 21, 1783. A descendant of the Montgolfier brothers, whose exploits fascinated Benjamin Franklin, will join a team to build an accurate replica of the fragile paper and canvas craft using 18th-century tools and materials.
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 1918, the fighter had become an efficient killing machine with a growing strategic impact on the outcome of the war. With the help of a unique collection of meticulously recreated flying replicas, NOVA traces the story of the designers, engineers, and brave pilots caught up in the race to dominate the skies over the western front.
Follow the paleontologists who are reconstructing this terrifying carnivore, a 53-foot-long behemoth with a huge dorsal sail, scimitar-like claws and superjaws. Bringing together experts in paleontology, geology, climatology and paleobotany, this special brings to life the lost world over which Spinosaurus reigned more than 65 million years ago.
To defend himself in the afterlife, the First Emperor of China, Qin Shi Huang, was buried in a vast mausoleum accompanied by around 9,000 life-sized terracotta statues. With exclusive access to groundbreaking new research, NOVA investigates the secrets of how and why the astonishing figures were made and the technology behind the still lethal and highly-advanced crossbows, spears, and swords carried by the clay warriors.
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.
When Neil Armstrong set foot on the moon, he won instant fame. Yet this accomplished engineer and test pilot was so determined to stay out of the limelight that few know the personal story of how his rare combination of talent, luck and experience led to his successful command of Apollo 11. NOVA presents an intimate portrait of an unassuming American hero through interviews with Armstrong’s family and friends.

Long before 9/11, a far deadlier, little-known attack from the ocean depths struck our shores, lasting three-and-a-half years and claiming 5,000 lives. Now, famed undersea explorer Bob Ballard, discoverer of the Titanic, investigates the wreck of one of the attack craft, a German submarine that lies at the bottom of the gulf just a few miles off New Orleans. U-166 was part of Operation Drumbeat, a highly successful U-boat operation that caught East Coast cities and shipping almost completely unprepared. Ballard probes the wreck and unravels a dramatic mystery in the official story of the sub's sinking.
