Season 38

01 Building the Great Cathedrals Episode 119th October 2010 Take a dazzling architectural journey inside those majestic marvels of Gothic architecture, the great cathedrals of Chartres, Beauvais and other European cities. Carved from 100 million pounds of stone, some cathedrals now teeter on the brink of catastrophic collapse. To save them, a team of engineers, architects, art historians, and computer scientists searches the naves, bays, and bell-towers for clues. NOVA investigates the architectural secrets that the cathedral builders used to erect their towering, glass-filled walls and reveals the hidden formulas drawn from the Bible that drove medieval builders ever upward. 02 Emergency Mine Rescue Episode 226th October 2010 This one-hour film chronicles the fate of the 33 miners trapped in a collapsed Chilean gold and copper mine in August 2010 and investigates the many challenges faced by both the miners and those working around the clock to bring them safely to the surface. NOVA was on-site at the San José mine in Chile by early September. Conferred special access, NOVA's film crew interviewed engineers, NASA experts, medical personnel, and key figures from the companies that provided drills and crucial rescue equipment to give a more detailed scientific account of the unfolding events. The resulting film, using footage from the scene as well as advanced animation, showcases the extraordinary feats of engineering as well as the biological and geological factors inherent in the rescue. "Emergency Mine Rescue" also examines the psychological and physiological impact of this kind of prolonged ordeal on the miners and those involved in the rescue efforts. 03 Trapped in an Elevator Episode 32nd November 2010 A documentary examining the ubiquitous transportation device as used in modern day and features a recounting of a real-life horror story of one individual's experiences when stuck in an elevator for an extraordinarily long period of time. 04 Dogs Decoded Episode 49th November 2010 "Dogs Decoded" reveals the science behind the remarkable bond between humans and their dogs and investigates new discoveries in genetics that are illuminating the origin of dogs—with surprising implications for the evolution of human culture. Other research is proving what dog lovers have suspected all along: Dogs have an uncanny ability to read and respond to human emotions. Humans, in turn, respond to dogs with the same hormone responsible for bonding mothers to their babies. How did this incredible relationship between humans and dogs come to be? And how can dogs, so closely related to fearsome wild wolves, behave so differently? 05 Secrets of Stonehenge Episode 516th November 2010 Dated to the late Stone Age, Stonehenge may be the best-known and most mysterious relic of prehistory. Every year, a million visitors are drawn to England to gaze upon the famous circle of stones, but the monument's meaning has continued to elude us. Now investigations inside and around Stonehenge have kicked off a dramatic new era of discovery and debate over who built Stonehenge and for what purpose. How did prehistoric people quarry, transport, sculpt, and erect these giant stones? Granted exclusive access to the dig site at Bluestonehenge, a prehistoric stone-circle monument recently discovered about a mile from Stonehenge, NOVA cameras join a new generation of researchers finding important clues to this enduring mystery. 06 Quest for Solomon's Mines Episode 623rd November 2010 Countless treasure-seekers have set off in search of King Solomon's mines, trekking through burning deserts and scaling the forbidding mountains of Africa and the Levant, inspired by the Bible's account of splendid temples and palaces adorned in glittering gold and copper. Yet to date, the evidence that has claimed to support the existence of Solomon and other early kings in the Bible has been highly controversial. In fact, so little physical evidence of the kings who ruled Israel and Edom has been found that many contend that they are no more real than King Arthur. In the summer of 2010, NOVA and National Geographic embarked on two cutting-edge field investigations that illuminate the legend of Solomon and reveal the source of the great wealth that powered the first mighty biblical kingdoms. These groundbreaking expeditions expose important new clues buried in the pockmarked desert of Jordan, including ancient remnants of an industrial-scale copper mine and a 3,000-year-old message with the words "slave," "king," and "judge." 07 Secrets Beneath the Ice Episode 728th December 2010 Almost three miles of ice buries most of Antarctica, cloaking a continent half again as large as the United States. But when an Antarctic ice shelf the size of Manhattan collapsed in less than a month in 2002, it shocked scientists and raised the alarming possibility that Antarctica may be headed for a meltdown. Even a ten percent loss of Antarctica's ice would cause catastrophic flooding of coastal cities unlike any seen before in human history. What are the chances of a widespread melt? "Secrets Beneath the Ice" explores whether Antarctica's climate past can offer clues to what may happen. NOVA follows a state-of-the-art expedition that is drilling three-quarters of a mile into the Antarctic seafloor. The drill is recovering rock cores that reveal intimate details of climate and fauna from a time in the distant past when the Earth was just a few degrees warmer than it is today. As researchers grapple with the harshest conditions on the planet, they discover astonishing new clues about Antarctica's past—clues that carry ominous implications for coastal cities around the globe. 08 Deadliest Earthquakes Episode 811th January 2011 In 2010, several epic earthquakes delivered one of the worst annual death tolls ever recorded. The deadliest strike, in Haiti, killed more than 200,000 people and reduced homes, hospitals, schools, and the presidential palace to rubble. In exclusive coverage, a NOVA camera crew follows a team of U.S. geologists as they enter Haiti in the immediate aftermath of the tragedy. The team hunts for crucial evidence that will help them determine exactly what happened deep underground and what the risks are of a new killer quake. Barely a month after the Haiti quake, Chile was struck by a quake 100 times more powerful, unleashing a tsunami that put the entire Pacific coast on high alert. In a coastal town devastated by the rushing wave, NOVA follows a team of geologists as they battle aftershocks to measure the displacement caused by the earthquake. Could their work, and the work of geologists at earthquake hot spots around the U.S., one day lead to a breakthrough in predicting quakes before they happen? NOVA investigates compelling new leads in this profound scientific conundrum. 09 Making Stuff: Stronger Episode 919th January 2011 What is the strongest material in the world? Is it steel, Kevlar, carbon nanotubes, or something entirely new? NOVA kicks off the four-part series "Making Stuff" with a quest for the world's strongest substances. Host David Pogue takes a look at what defines strength, examining everything from steel cables to mollusks to a toucan's beak. Pogue travels from the deck of a U.S. naval aircraft carrier to a demolition derby to the country's top research labs to check in with experts who are re-engineering what nature has given us to create the next generation of strong stuff. 10 Making Stuff: Smaller Episode 1026th January 2011 How small can we go? Could we one day have robots taking "fantastic voyages" in our bodies to kill rogue cells? The triumphs of tiny are seen all around us in the Information Age: transistors, microchips, laptops, cell phones. Now, David Pogue takes NOVA viewers to an even smaller world in "Making Stuff: Smaller," examining the latest in high-powered nano-circuits and micro-robots that may one day hold the key to saving lives. 11 Making Stuff: Cleaner Episode 112nd February 2011 Can innovations in materials science help clean up our world? In "Making Stuff: Cleaner," David Pogue explores the rapidly developing science and business of clean energy and examines alternative ways to generate it, store it, and distribute it. Is hydrogen the way to go? What about lithium batteries? Does this solve an energy problem or create a new dependency? Pogue investigates the latest developments in bio-based fuels and in harnessing solar energy for our cars, homes, and industry in a program full of the stuff of a sustainable future. 12 Making Stuff: Smarter Episode 129th February 2011 "Making Stuff: Smarter" looks at materials that respond to their environments and even learn, such as an airplane wing that changes shape as it flies. Scientists are turning to nature in developing such "smart" stuff. Sharkskin, for instance, has inspired a substance that, when sprayed in hospitals, could eliminate antibiotic-resistant bacteria. David Pogue visits a scientist who has even created a material that can render objects invisible. "Smarter" concludes with a vision of the ultimate in "life-like" stuff: programmable matter that could create a duplicate of a human being. 13 Smartest Machine on Earth Episode 139th February 2011 Augmenting human intelligence is a lot tougher than it looks, and the promise of "Hal" from 2001: A Space Odyssey is still just a fantasy. But scientists are edging closer with machines like "Watson," an IBM computing system that is gearing up for a first-of-its-kind challenge: taking on human contestants on the game show Jeopardy! With a brain the size of 2,400 home computers and a database of about 10 million documents, will Watson be able to compute its way to victory? Given the complexity of human language, could any computer truly understand it? It remains to be seen if this amalgam of circuits and silicon can really take us closer to the dream of a fully developed artificial intelligence, a truly "conscious" machine. Win or lose, the difficulty of mimicking the human thought process with software is showing artificial-intelligence researchers that there's more than one way to be "intelligent." 14 Crash of Flight 447 Episode 1416th February 2011 On June 1, 2009, Flight AF447, an Air France Airbus A330 flying from Rio de Janeiro to Paris, disappeared over the Atlantic Ocean with the loss of all 228 lives. How could a state-of-the-art airliner with elaborate electronic safety and navigation features and a faultless safety record simply fall out of the sky? NOVA assembles a team of seasoned pilots, engineers, and safety experts to examine the evidence that emerged in the weeks following this horrific disaster. What led Flight 447's crew to fly straight into a towering thunderstorm? With expert testimony, satellite weather images, and messages transmitted by the doomed plane's computer system, NOVA pieces together the fatal chain of events. 15 Venom: Nature's Killer Episode 1523rd February 2011 Over the millennia, thousands of creatures have developed that most sophisticated of biological and chemical weapons: venom. These complex chemicals can scramble your brain signals, paralyze your muscles, puncture your blood cells, even begin digesting you from within. But nature's most potent toxins might also contain the keys to a new generation of advanced drugs. Such drugs might help doctors treat heart attacks, cancer, diabetes, and other serious illnesses. Follow NOVA crews as they join scientists on a dangerous quest to track down and capture the world's most venomous animals - to find out both how they can kill us, and how they can save us. 16 Japan's Killer Quake Episode 1630th March 2011 In its worst crisis since World War II, Japan faces disaster on an epic scale: a death toll likely in the tens of thousands, massive destruction of homes and businesses, shortages of water and power, and the specter of nuclear meltdown.
