What will happen to Los Angeles when the big one strikes? The answer may be found at an earthquake site over 6,000 miles away. Examines why the 7.4 earthquake that struck Izmit, Turkey, killed over 17,000 people in 1999. Explains why even trained rescuers fight an impossible battle. Offers suggestions as to what Los Angeles must do to be better prepared for the earthquake that scientists see as inevitable, and to prevent this same tragedy from happening.

Inside a cylinder that is about the size of a roll of paper towels lives a circuit board filled with sensors. It's called a dropsonde, or “sonde” for short. As the sonde falls through the air after being dropped for an airplane, its sensors gather data about the atmosphere. Dropsondes have a huge impact on understanding hurricanes and the ability to predict hurricanes. Part of the National Science Foundation Series “Science Nation.”
In this episode, Pete Nelson describes his passion for building tree houses, and inventor Anthony Lenzo describes how he plans to turn a smart phone into an underwater camera. Host Mo Rocca features an architect that is creating vertical gardens on Mexico's highways, and the final story explains why the railroad world ditched stream engines for diesel. Part of "The Henry Ford Innovation Nation With Mo Rocca" series.
Like everyone else, George Huber knows money doesn't grow on trees. But, ask him where gasoline comes from and he won't just tell you, he'll show you. To fully understand, Science Nation recently went with Huber to a local lumber yard in Amherst, Mass. A lumber yard is the perfect place to find cellulose, the key building block in plant cells and the organic material that gives plants their structure. So what does cellulose have to do with gasoline? A lot.
As shown on the History Channel. Over 20 years ago, Mount St. Helen's--thought to be dormant--shocked America when it exploded. It is an acidic volcano--the magma beneath is full of volatiles making it highly explosive. A new plug has formed in its throat and is rising. When it blows, it will be like uncorking a champagne bottle, releasing pressure below and allowing dissolved gases to escape and explode. The question is, When will it blow again?
Host Peter Tonge visits the Weston Maple Sugar Project in Weston, Massachusetts. Shows the process of making maple syrup from tapping a maple sugar tree to boiling sap in a sugar shack. The second part of the program focuses on the basics of planning a garden in late winter. Also explains how to mix and apply liquid fertilizers. Originally aired as an episode of "The Good Green Earth."
Already parts of the world suffer from lack of water, and with increasing demand it's expected to get worse. To better understand and predict drought, thirty universities are collaborating in a multidisciplinary effort called the Shale Hills Project. Among the studies, is field research following the life cycle of water along the Susquehanna River Basin. With support from the National Science Foundation, civil engineer Chris Duffy and his team at Penn State are tracking several aspects of rainfall to better understand the relationship between the flow of water, drought prone areas, and urban populations.
Explores the open savannahs of Africa, particularly the mammals that inhabit them and the trees that border the grasslands. Shows how the different animals interact with each other and the non-living elements of their habitat to maintain a healthy balance. Also investigates the threat from an increasing human population for homes, food, other resources, and the resultant threat to the survival of many animal groups. Looks at international breeding programs around the world, which were established to protect these animals and enable them to reproduce in captivity, so their gene pool is preserved.
Elizabeth Hadly has been studying biodiversity in Yellowstone National Park for 30 years. Accompanied by biologist Sean Carroll, she demonstrates different ways in which climate change is impacting the park’s ecosystems. Bark beetles are surviving the winter at higher elevations and killing a large number of white-bark pine trees, disrupting the food web that includes squirrels and grizzly bears. Climate change is also causing ponds to dry up, reducing the pond habitat and decimating the local amphibian population. Although the park provides protected environments for animals, it is not immune from global threats like climate change.
Part of "Show Me Science" series. Are animals intelligent? Bees communicate with each other. Monkeys use rocks and sticks to help them get food. Is this instinctual or is it evidence of thought? Some scientists believe that one measure of intelligence is self-awareness, and that an animal's reaction to its own image in a mirror can tell us whether or not it is self-aware. Looks at fish, birds, monkeys, and primates and their reactions to themselves in a mirror. Researchers look for signs of self-recognition as they observe, record, and interpret the reactions of these animals. Includes suggestions for careers in this field of study.
Moko is an explorer. As he travels the world continent by continent, he makes many friends and discovers many natural phenomena which sometimes delight him, and other times scare him. Each animated episode recounts an adventure and takes an "original story" approach to explaining these natural phenomena. In this episode, Moko is enjoying Alarick's country. The warm weather has returned, the trees have flowered and food is plentiful. Moko thinks now the cold has passed life here will be easy. An old man tells him that the cold will return, but Moko doesn't want to believe him and lets time pass. He sees the beauty of the changing seasons and one morning...winter!
The first in a series of five documentaries plots the course of the river, from its source to its delta. In a succession of spectacular images we see the extraordinary geographical route that the Mekong takes, from the Tibetan plateau, down the mountains of the Yunnan Province in China, then through the tropical valleys and virgin forests of Burma, Cambodia, Laos and Thailand before reaching the green plains of Vietnam. In the tropical forest, nature abounds with wild animal species, rare plants and flowers. In Laos', whole villages still pray to the Gods of Trees while in Thailand a hunter shows how the hunting of Asian elephants for preservation, now forbidden, was practiced. Series: The Soul of Southeast Asia
Moko is an explorer. As he travels the world continent by continent, he makes many friends and discovers many natural phenomena which sometimes delight him, and other times scare him. Each animated episode recounts an adventure and takes an "original story" approach to explaining these natural phenomena. In this episode, Moko thinks that somewhere lies a creature that blows so hard that it makes the boughs of trees quiver and creates the desert dunes. He believes that the clouds flee before the wind comes because they are afraid of the creature. He decides to go look for it. Tired after walking beneath the hot sun, a fresh, light breeze makes his rest more pleasant. However, the creature is actually the Harmattan blowing over West Africa.
The Magic School Bus is an award winning animated children’s television series based on the book series of the same title by Joanna Cole and Bruce Degen. It is notable for its use of celebrity talent and being both highly entertaining and educational. The kids rent a rainforest cocoa tree as an Earth Day present for Ms. Frizzle. But when the harvest arrives, there's only one shriveled cocoa bean and a note from Inspector 47. The note reports that the tree isn't producing beans. Ms. Frizzle takes the class to the rain forest to meet the inspector and find out why the trees aren’t producing cocoa beans.
Moko is an explorer. As he travels the world continent by continent, he makes many friends and discovers many natural phenomena which sometimes delight him, and other times scare him. Each animated episode recounts an adventure and takes an "original story" approach to explaining these natural phenomena. In this episode, the snow's thaw is drawing to a close and the mountain is shedding its white robe. Alarick and Moko are fishing in one of the mountain's springs and are catching nothing. They ask an old wise man to tell them where there might be fish. He points them towards the road to the "Ancient Mountain." They follow the road the old man told them about and reach a green luxuriant hill covered with fruit trees and streams. They think that this hill--smaller than their mountain, richer and greener--younger and simply hasn't grown up yet. Moko and Alarick explore the natural process of erosion.
Moko is an explorer. As he travels the world continent by continent, he makes many friends and discovers many natural phenomena which sometimes delight him, and other times scare him. Each animated episode recounts an adventure and takes an "original story" approach to explaining these natural phenomena. In this episode, having spent the night up in the giant tree, Moko is woken up by the sound of an arrow piercing through an enormous fruit. Afraid that a giant must be coming, he climbs down the tree and tries to flee, but gets lost in the Amazon Forest. This is when he meets Totemie, a young Amazonian girl who knows the forest better than anyone. She invites Moko to her village and they walk through an incredible maze of plants, roots and trees of all kinds. Without Totemie, Moko would be completely lost. He believes the forest introduced his new friend so that he could learn a few of its secrets.
