Building The Great Cathedrals (Episode #3711#)
KQED 9: Wed, Dec 25, 2013 -- 9:00 PM
Carved from 100 million pounds of stone, soaring effortlessly atop a spiderweb of masonry, Gothic cathedrals are marvels of human achievement and artistry. But how did medieval builders reach such spectacular heights? Consuming the labor of entire towns, sometimes taking 100 years to build, these architectural marvels were crafted from just hand tools and stone. Many now teeter on the brink of catastrophic collapse. To save them, an international team of engineers, architects, art historians and computer scientists searches the naves, bays, and bell towers for clues to how the dream of these heavenly temples on earth came true. NOVA's teams perform hands-on experiments to investigate and reveal the architectural secrets that the cathedral builders used to erect their soaring, glass-filled walls. This program reveals the hidden formulas, drawn from the pages of the Bible itself, that drove medieval builders ever upward.

Extreme Ice (Episode #3604H)
KQED World: Fri, Dec 20, 2013 -- 5:00 AM
In collaboration with National Geographic, Nova follows the exploits of acclaimed photojournalist James Balog and a scientific team as they deploy time-lapse cameras in risky, remote locations in the Arctic, Alaska, and the Alps. Grappling with blizzards, fickle technology, and climbs up craggy precipices, the team must anchor cameras capable of withstanding sub-zero temperatures and winds up to 170 mph. The goal of Balog's team's perilous expedition: to create a unique photo archive of melting glaciers that could provide a key to understanding their runaway behavior and their potential to drive rising sea levels.
Some models now project a one-meter sea level rise over the next century, which could displace millions of people everywhere from Florida to Bangladesh and require trillions of dollars in new coastal infrastructure investments. But, alarmingly, these models don't reflect recent findings that glaciers in Greenland and Antarctica are melting at an ever-faster rate. What explains this alarming acceleration, and just how do you figure out what's happening inside a gigantic wall of ice? In this high-action scientific adventure, Nova investigates the mystery of the mighty ice sheets that will affect the fate of coastlines around the world.

Ultimate Mars Challenge (Episode #3915H)
KQED 9: Wed, Dec 11, 2013 -- 9:00 PM
It could be NASA's last chance to set wheels down on Mars until the end of the decade: in August 2012, a rover named Curiosity touched down inside Mars' Gale Crater, carrying 10 new instruments that advanced the quest for signs that Mars might have once been suitable for life. But Curiosity's mission is risky. After parachuting through the Martian atmosphere at twice the speed of sound, Curiosity is gently lowered to the planet's surface by a "sky crane." This first-of-its-kind system has been tested on Earth, but will it work on Mars?
With inside access to the massive team of scientists and engineers responsible for Curiosity's on-the-ground experiments, Nova is there for the exhilarating moments after Curiosity's landing - and for the spectacular discoveries to come. But no rover does it alone: Curiosity is joining a team that includes the Mars Odyssey, Express and Reconnaissance orbiters, along with the tireless Opportunity rover. As we reveal the dynamic new picture of Mars that these explorers are painting, we discover the questions raised by 40 years of roving Mars: How do we define life? How does life begin and what does it need to survive? Are we alone in the universe?

A Walk to Beautiful (Episode #3506)
KQED World: Fri, Dec 6, 2013 -- 5:00 AM
This program, a story of hope and survival in contemporary Ethiopia, presents the stories of five Ethiopian women who have been devastated by obstetric fistula, a common aftermath of neglected childbirth. An obstetric fistula is a hole that forms between the vagina and the bladder (and in some cases the rectum) during prolonged, obstructed labor. Affecting over two million women worldwide, this horrific injury leaves victims incontinent, often suffering nerve damage and in some cases unable to bear children again. Rejected by their husbands and ostracized by their communities, these women are often left to spend the rest of their lives alone, isolated and ashamed -- unless they can get help. NOVA follows these women on their journey to the Addis Ababa Fistula Hospital, where they find health and solace for the first time in years. The dignity of their struggle connects viewers to the plight of countless women in the developing world who face daily challenges from malnutrition, child marriage and lack of obstetric care.
