Vaccines - Calling The Shots (Episode #4114H)

KQED 9: Wed, Aug 26, 2015 -- 9:00 PM

Diseases that were largely eradicated 40 years ago are returning. Across the world, children are getting sick and dying from preventable conditions because nervous parents are skipping their children's shots. How do parents decide whether to vaccinate or not, and what are the risks to the child and to society? Featuring research scientists, pediatricians, psychologists, anthropologists, and parents, this program travels the globe to look at the science behind vaccinations, track epidemics, and investigate the serious human costs of opting out.

Ben Franklin's Balloons (Episode #4117H)

KQED 9: Wed, Aug 19, 2015 -- 9:00 PM

The first stage in the adventure of human flight began with daring inventors and aeronauts in 18th-century Paris, where a handful of brilliant and colorful pioneers developed all the essential features of today's hot air and gas balloons. Their exploits fascinated Benjamin Franklin, who was serving in Paris as the American ambassador. To explore this burst of innovation, Nova re-creates key flights, including the world's first manned voyage on November 21, 1783. A descendant of the Montgolfier brothers, who invented the hot-air balloon, will join a team to build an accurate replica of the fragile paper and canvas craft using 18th-century tools and materials. Nova evokes the thrilling and daunting prospect that the balloon pioneers faced as they left Earth for the first time.

Join Nova for New Horizon's historic flyby of Pluto, the culmination of the spacecraft's nine-year, three-billion-mile journey to reveal the first-ever detailed images of this strange, icy world at the very edge of our solar system.

Mystery of Easter Island (Episode #3914H)

KQED Life: Tue, Aug 18, 2015 -- 3:00 AM

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.

Secrets of the Viking Sword (Episode #3913H)

KQED Life: Tue, Aug 18, 2015 -- 2:00 AM

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 "Mystery of the Viking Sword."

Nuclear Meltdown Disaster (Episode #4214H)

KQED World: Sat, Aug 1, 2015 -- 10:00 PM

Four years ago, a devastating earthquake and tsunami triggered a disastrous meltdown at the Fukushima Daiichi nuclear power plant. But at the same time, just seven miles away, the heroic efforts of plant operators under the leadership of Naohiro Masuda saved a second plant, Fukushima Daini. Now Masuda faces the daunting challenge of cleaning up Daiichi, where a witches' brew of radioactive groundwater leaks into the Pacific every day, and three melted cores remain steaming hot and lethally unapproachable.
Now, with unprecedented access, Nova reveals the little-known story of how Masuda and his team averted disaster at Daini and how workers are struggling to clean up the mess at Daiichi. With billions of dollars and the future of the nuclear energy industry on the line, can Japan recover from disaster? The world is watching the fight for Fukushima.

Escape from Nazi Alcatraz (Episode #4112H)

KQED 9: Sat, Aug 1, 2015 -- 3:00 AM

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 aerospace 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 90 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.
