Mystery of a Masterpiece (Episode #3904H)

KQED Plus: Tue, Jan 24, 2017 -- 11:00 AM

In October 2009, a striking portrait of a young woman in Renaissance dress made world news headlines. Originally sold two years before for around $20,000, the portrait is now thought to be an undiscovered masterwork by Leonardo da Vinci worth more than $100 million. How did cutting edge imaging analysis help tie the portrait to Leonardo? Nova meets a new breed of experts who are approaching "cold case" art mysteries as if they were crime scenes, determined to discover "who committed the art," and follows art sleuths as they deploy new techniques to combat the multi-billion dollar criminal market in stolen and fraudulent art.

Secrets of Noah's Ark (Episode #4212H)

KQED World: Sun, Jan 22, 2017 -- 3:00 PM

A 3700-year-old inscribed clay tablet reveals a surprising new version of the Biblical flood story, complete with how-to instructions for assembling an ark. Following the directions, expert boat builders assemble and launch a massive reed boat.

The Nuclear Option (Episode #4402H)

KQED Life: Tue, Jan 17, 2017 -- 8:00 PM

Five years after the earthquake and tsunami that triggered the unprecedented trio of meltdowns at the Fukushima Daiichi nuclear power plant, scientists and engineers are struggling to control an ongoing crisis at the wrecked plant. What's next for Fukushima? What's next for Japan? And what's next for a world that seems determined to jettison one of our most important carbon-free sources of energy? Despite the catastrophe, a new generation of nuclear power seems poised to emerge phoenix-like from the ashes of Fukushima. NOVA investigates how the realities of climate change, the inherent limitations of renewable energy sources, and the optimism and enthusiasm of a new generation of nuclear engineers is seeding a renaissance in nuclear technology, all while the most recent disaster is still being managed. What are the lessons learned from Fukushima? And how might we be able to build a safe nuclear future?

Secrets of the Sky Tombs (Episode #4401H)

KQED 9: Wed, Jan 4, 2017 -- 9:00 PM

A team of scientists and explorers probe high altitude caves in the Tibetan Himalayas looking for clues to how humans found their way into this forbidding landscape and adapted their bodies to survive. ? Along the way they discover evidence of ritual burials, thousands of years old: skeletons, mummies, and evidence of practices designed to ward off ancient vampires and even zombies.

Building Pharaoh's Chariot (Episode #4005H)

KQED World: Sun, Jan 1, 2017 -- 3:00 PM

Around 3,600 years ago, reliefs in Egyptian tombs and temples depicted 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 this film, 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.
