Asteroid: Doomsday or Payday?
The asteroid that exploded over Siberia—injuring more than 1,000 and damaging buildings in six cities—was a shocking reminder that Earth is a target in a cosmic shooting range. From the width of a football field to the size of a small city, these space rocks have the potential to be killers. In a collision with Earth, they could set off deadly blast waves, raging fires and colossal tidal waves. But some audacious entrepreneurs look up at asteroids and see payday, not doomsday. Some asteroids are loaded with billions of dollars' worth of elements like iron, nickel, and platinum. NASA is planning an ambitious mission to return samples from a potentially hazardous asteroid, and would-be asteroid miners are dreaming up their own program to scout for potentially profitable asteroids. Will asteroids turn out to be our economic salvation—or instruments of extinction?

Ghosts of Murdered Kings
In the rolling hills of Ireland's County Tipperary, a laborer harvesting peat from a dried-up bog spots the remnants of a corpse and stops his machine just in time, revealing a headless torso almost perfectly preserved and stained dark brown by the bog. Archeologists recognize the corpse as one of Europe's rare bog bodies. They hunt for clues to the identity and violent death circumstances of victims unearthed in Ireland's bogs and reveal the strange beliefs of the long-vanished peoples of Europe - the Celts.
s41e14 Roman Catacomb Mystery 2014-02-06 02:00
Roman Catacomb Mystery
Beneath the streets of Rome lies a city of the dead known as the Catacombs—a labyrinth of tunnels, hundreds of miles long, lined with the neatly laid out tombs of the citizens of ancient Rome. Here, in 2002, maintenance workers fixing a broken water main stumbled upon a previously unknown burial chamber like none other in the complex. It was a mass grave of hundreds of bodies spread across six roughly carved caverns, locked away for nearly 2000 years. Who were these people? And can we discover, after all these centuries, what killed them? Could they be Christian martyrs massacred by the Emperor? Or were they felled by a deadly plague? In "Roman Catacomb Mystery," NOVA's forensic investigation follows a trail of ancient clues to uncover new secrets of life, death, and disease in the heyday of a mighty empire.

s41e16 Wild Predator Invasion 2014-04-03 01:00
Wild Predator Invasion
Over the last few centuries we have shot, trapped, and skinned the predators that formerly thrived at the top of the food chain in the wild. Wild bears, wolves, and big cats are all in retreat, and a growing number of scientists are discovering that by eliminating predators, we have changed the environment. Removing predators from the wild has thrown ecosystems off-kilter, triggering domino effects that scientists are just beginning to understand. In "Wild Predator Invasion," NOVA follows scientists who are trying a simple but controversial solution: returning apex predators—like wolves, bears, and panthers—to their natural environments. Can these newly reintroduced predators restore the natural balance of their ecosystems without threatening the humans who live among them?
s41e17 Inside Animal Minds: Bird Genius 2014-04-10 01:00
Inside Animal Minds: Bird Genius
What would it be like to go inside the mind of an animal? Now, the revolutionary science of animal cognition is revealing hard evidence about how animals understand the world around them, uncovering their remarkable problem-solving abilities, and exploring the complexity of their powers of communication and even their emotions. In the three-hour special "Inside Animal Minds," NOVA explores these breakthroughs through three iconic creatures: dogs, birds, and dolphins. We'll travel into the spectacularly nuanced noses of dogs and wolves and ask whether their reliance on different senses has shaped their evolution. We'll see through the eyes of a starling in flight and test the tool-using skills of one of the smartest birds, the crow. We'll listen in as scientists track dolphins in the Caribbean and elephants on the African savannah, trying to unlock the secrets of animal communication. As we discover how researchers are pushing the animal mind to its limits, we'll uncover surprising similarities to—and differences from—the human mind.When it comes to intelligence, we humans are clearly the most gifted animals around. But what makes us so special? Is it our ability to make and use tools? To solve complex problems? Or plan for the future? It might seem that way, but today, researchers are discovering other creatures with impressive brains that have mastered all those skills. Surprisingly, many are bird brains. Crows bend and shape sticks to create custom-made spears for hunting grubs, and they are just one among a growing list of bird species whose impressive problem-solving abilities are shocking scientists and revolutionizing our understanding of animal intelligence. At the head of the class, we meet animals like Muppet, a cockatoo with a talent for picking locks; 007, a wild crow on a mission to solve an eight-step puzzle for the first time ever; and Bran, a tame raven who can solve a puzzle box so quickly that his performance has to be captured with high-speed photography. But are these skills really evidence of high intelligence, or just parlor tricks, the result of training and instinct? To find out, NOVA tests the limits of some of the planet's brainiest animals, searching for the secrets of a problem-solving mind.

Inside Animal Minds: Dogs & Super Senses

As we discover how researchers are pushing the animal mind to its limits, we'll uncover surprising similarities to—and differences from—the human mind.What is it like to be a dog, a shark, or a bird? Long the subject of human daydreams, this question is now getting serious attention from scientists who study animal senses. The senses define our experience of the world—they shape our minds and help make us what we are. Humans rely on smell, sight, taste, touch, and sound, but other animals have super-powered versions of these senses, and a few, like electrically-sensitive sharks, even have extra senses we don't have at all. From a dog who seems to use smell to tell time to a dolphin who can "see" with his ears, we will discover how animals use their senses in ways we humans can barely imagine. But it's not just the senses that are remarkable—it's the brains that process them. How does a swallow's tiny, one-gram brain take in the flood of visual information that enables the bird to whiz within inches of buildings while flying at 40 miles per hour? How does a dog's mind turn the sight of a hand signal into the happy anticipation of a treat? How has the evolution of the dog—from its wolf ancestors–reshaped its brain? NOVA goes into the minds of animals to "see" the world in an entirely new way.

What forces of evolution drive brains to become more complex? Many scientists believe the secret lies in our relationships. Throughout the animal kingdom, some of the cleverest creatures—including humans—seem to live in complex social groups, like dolphins, elephants, and apes. Could the skills required to keep track of friend and foe make animals smarter? To find out, NOVA goes inside the social lives of some of the smartest animals on the planet. Off the coast of Florida, we see dolphins team up to catch fish by whipping up a wall of muddy water that drives the meal right into their companions' waiting mouths. It seems that the dolphins are working together to plan their hunt. But are they really? Biologists go on a quest to decipher the secrets of animal societies, from the seas of the Caribbean to the plains of Africa. Do dolphins and elephants have "language?" Do chimps have a sense of fairness? And are any animals besides ourselves capable of feeling empathy?
s41e20 Why Sharks Attack 2014-05-08 01:00
Why Sharks Attack
In recent years, an unusual spate of deadly shark attacks has gripped Australia, resulting in five deaths in ten months. At the same time, great white sharks have begun appearing in growing numbers off the beaches of Cape Cod, Massachusetts, not far from the waters where Steven Spielberg filmed the ultimate shark fright film, Jaws. What's behind the mysterious arrival of this apex predator in an area where they've rarely been seen for hundreds of years? Are deadly encounters with tourists inevitable? To separate fact from fear, NOVA teams up with leading shark experts in Australia and the United States to discover the science behind the great white's hunting instincts. Do sharks ever target humans, or is each attack a tragic case of mistaken identity? And can a deeper understanding of shark senses lead scientists to design effective deterrents and help prevent future attacks?
