Nature “Cracking the Koala Code” at 7 pm
This program examines the day-to-day dramas of an extended family of koalas, seen through the eyes of the scientists studying their every move and vocalization. Fascinating social dynamics include territorial displays, vicious fighting and the surprising life and loves of a “traveling salesman,” a rogue male who truly plays the field. New science even “cracks the koala communication code,” providing insights into their basic language and social structure.
NOVA “The Great Inca Rebellion” at 8 pm
In an impoverished suburb of Lima, in an ancient cemetery crammed with more than 1,000 pre-Columbian mummies, Peruvian archaeologist Guillermo Cock makes a startling find. He discovers dozens of corpses that differ from all the rest: they were hastily buried and disfigured by appalling wounds and fractures inflicted by steel blades and crude bullets. Forensic experts diagnose these remains as victims of a little-known battle that pitted club-wielding Inca warriors against Spanish cavalry. The battle turns out to be a decisive turning point that helps explain a long-standing mystery about the Spanish conquest of Peru. How, in 1532, did a tiny band of Spanish soldiers crush the mighty Inca empire, then the most powerful civilization in the Americas, with a network of roads that spanned over 2,000 miles? Were the conquistadors’ obvious advantages — steel arms, gunpowder and horses — the key to their success, as is usually supposed? Or were disease and civil war more decisive factors that were downplayed by the Spanish chroniclers? With the help of this new evidence from the Lima cemetery, NOVA reveals the untold final chapter of the conquest: not the Spanish walkover familiar from popular accounts, but rather a protracted and complex war of astonishing brutality that almost led to the Spanish losing their precarious foothold in the Andes.
Bones of Turkana at 9 pm
Follow famed paleoanthropologist Richard Leakey and his wife, Meave, daughter Louise and their colleagues as they work in the arid northern regions of Kenya’s Turkana Basin to unravel the mysteries of human evolution. While one of the Leakeys’ goals is to demonstrate the complexity and truth of human evolution, they also seek to show how the qualities that we proudly call human were all born in Africa. The story that emerges in the film is exciting, emotional, contemplative, occasionally funny and, in the end, transforming. This is Africa at its most beautiful and harshest.
Nature “Born Wild: The First Days of Life” at 7 pm
From the moment of their birth, baby animals in the wild can face almost anything — from a large social group of interested caregivers, to a potentially deadly group of relatives, to one or two devoted parents, to complete abandonment and no available help at all. Yet they all have something in common. They must learn whom to trust, what to fear and when to act — all in the first days of life. Child care involves instinct, but also experience and choices, some of which can be devastatingly hard. Find out how being born in the wild has evolved over time, and how animals interacting with their young, wrestling with the feelings and dilemmas that come with raising a baby, can mirror our own experiences.
NOVA “Smartest Machine On Earth” at 8 pm
What’s so special about human intelligence and will scientists ever build a computer that rivals the flexibility and power of a human brain? In “Artificial Intelligence,” NOVA takes viewers inside an IBM lab where a crack team has been working for nearly three years to perfect a machine that can answer any question. The scientists hope their machine will be able to beat expert contestants in one of the USA’s most challenging TV quiz shows — Jeopardy, which has entertained viewers for over four decades. “Artificial Intelligence” presents the exclusive inside story of how the IBM team developed the world’s smartest computer from scratch. Now they’re racing to finish it for a special Jeopardy airdate in February 2011. They’ve built an exact replica of the studio at its research lab near New York and invited past champions to compete against the machine, a big black box code — named Watson after IBM’s founder, Thomas J. Watson. But will Watson be able to beat out its human competition?

The historic nuclear accident at Chernobyl is now 25 years old. Filmmakers and scientists set out to document the lives of the packs of wolves and other wildlife thriving in the “dead zone” that still surrounds the remains of the reactor.
Nova “Secrets of the Sun” at 8 pm
It contains 99.9 percent of all the matter in our solar system and sheds hot plasma at nearly a million miles an hour. The temperature at its core is a staggering 27 million degrees Fahrenheit. It convulses, it blazes, it sings. You know it as the sun. Scientists know it as one of the most amazing physics laboratories in the universe. Now, with the help of new spacecraft and Earth-based telescopes, scientists are seeing the Sun as they never have before and even re-creating what happens at the very center of the Sun in labs here on Earth. Their work will help us understand aspects of the sun that have puzzled scientists for decades. But more critically, it may help us predict and track solar storms that have the power to zap our power grid, shut down telecommunications, and ground global air travel for days, weeks, or even longer. Such storms have happened before-but never in the modern era of satellite communication. SECRETS OF THE SUN reveals a bright new dawn in our understanding of our nearest star-one that might help keep our planet from going dark.
