Monitoring water quality is vital to make sure dangerous bacteria doesn't creep into drinking water or overcome sewage treatment plants. With support from the National Science Foundation, engineers at the Monterey Bay Aquarium Research Institute have developed the Environment Sample Processor (ESP), a "DNA lab in a can." The size of a trash can, it can be placed in the open ocean or at water treatment facilities to identify potentially harmful bacteria, algae, larvae, and other microscopic organisms in the surrounding waters. It can monitor and send results back to the lab in real time to monitor water quality. Now, the engineers are modifying the ESP so it can go mobile, working from an autonomous underwater vehicle (AUV).

Microorganisms affect everyone. Some are helpful, while others are harmful. Explores pathogenic microorganisms that can cause diseases like sore throats, influenza, tuberculosis, and HIV; decomposer microorganisms that decay rotting plant and animal matter, returning important nutrients back into the soil; and microorganisms that are also being used in the fuel industry to develop new nonpetroleum based products. Overviews food spoilage microorganisms such as mold that can ruin stored food. Explains other bacteria and yeasts are vital to the production of food and drinks like yogurt and bread, along with beer and wine. Examines where they come from and some examples of positive uses relating to many foods we eat.
Everywhere one looks in Southern Louisiana there's water: rivers, bayous, swamps, the Mississippi River, and the Gulf of Mexico. And everyone in Cajun Country has a water story, or two or three or more. Its waterways support the biggest economies in Louisiana - a $70 billion a year oil and gas industry, a $2.4 billion a year fishing business, tourism and recreational sports. But these waterways are also home to some insidious polluters along a 100-mile-long stretch of the Mississippi known "Cancer Alley," the world's largest Dead Zone in the Gulf of Mexico and erosion that is costing the coastline twenty five square miles of wetlands a year.
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. Ralphie wants to catch salmon to serve at the annual school picnic, but he can't find any at his favorite fishing spot. Where could all the salmon have gone? The kids are soon "Frizzled" inside a salmon bus that has an uncontrollable urge to head upriver. Using its sense of taste and smell, it swims the long journey to a shallow freshwater stream mile away. Why has the bus, which thinks it's a salmon, gone to all this trouble?
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. When Phoebe tries to grow a big vine for her school's production of Jack and the Beanstalk, all she ends up with is a stunted little sprout. To help out, Ms. Frizzle turns her into a real vine. But to grow tall, Phoebe needs to figure out how plants eat. To unearth the amazing ways plants make their own food, Ms. Frizzle and the kids shrink down and dig deep in a quest to root out the facts.
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.

A quick glance at the marsh next to Saquatucket Harbor in Harwich Port, Massachusetts, reveals right away that some of the grass is missing. The cordgrass there, and all around Cape Cod, has been slowly disappearing for decades. Marine ecologist Mark Bertness of Brown University studies this critical ecosystem, which protects our coastal environment by nurturing a complex web of plants and animals, filtering nutrients, and serving as a critical storm barrier. Bertness says the marshes are being overrun by purple marsh crabs because their main predators, blue crab and finfish, are being overfished. So, the purple marsh crabs are free to gorge on healthy fields of cordgrass and once done feeding, they leave behind nothing but lumpy fields of mud.
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. To celebrate the founding of Walkerville, Ms. Frizzle's class sculpts a stone likeness of its founding father, Captain Walker. But as they add the finishing touches, the statue tumbles down the mountain. Ms. Frizzle turns the bus into a giant boulder and the kids into rock kids. They bump down the mountain in a desperate attempt to save the statue. By the time they reach the celebration at the base of the mountain, they've been pushed, tossed, sanded, polished, and eroded by water.
Since the last ice age, plants in the Alaskan Arctic have been taking carbon out of the atmosphere and locking it away in the soil. But now, the permafrost is starting to thaw. That means all those microbes are about to find themselves at an all-you-can-eat carbon buffet. With support from the National Science Foundation, ecologist Matthew Wallenstein and a team from Colorado State University have come to the Toolik Field Station, deep inside the Arctic Circle, to drill soil cores for study. The researchers are trying to find out more about how microbes in the soil are cycling carbon from the Earth to the atmosphere. Part of the National Science Foundation Series “Science Nation.”
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 class is enjoying a normal summer day at the beach until Ms. Frizzle discovers a letter from "Uncle Shelby," who wants the class to look after his beachfront property. The kids soon discover that this "luxurious" accommodation is only a tiny spot on the shoreline. Why would anyone want to live in a spot where they're battered by waves at high tide and baked by the sun at low tide? To find out, Ms. Frizzle turns the kids into mussels.
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.
The rock pocket mouse is a living example of Darwin's process of natural selection. Not only is evolution happening right now everywhere around us, but adaptive changes can occur in a population with remarkable speed. This speed is essential if you're a desert mouse living in an environment where a volcanic eruption can reverse selective pressure in nearly an instant. Features Dr. Michael Nachman, whose work in the field and in the lab has quantified the selective pressure of predators and identified the genes involved in adaptation. From ecosystem to molecules, pocket mice show the viewers how random changes in the genome can take many paths to the same adaptation-a colored coat that hides them from predators.
In the Pacific Northwest, people are stripping moss for the horticultural trade at such an alarming rate that it's now illegal to harvest it. Ecologist Nalini Nadkarni knows that moss is a key component to the eco-system of the region, which makes it important to study. But this globe-trotting scientist at The Evergreen State College needed a lot of help recording research data from some folks who have much more time than she does. Where better to find potential research assistants with lots of time on their hands than the nearby medium security Cedar Creek Corrections Center? With support from the National Science Foundation, Nadkarni’s idea has been so successful that now the prisoners are starting bee keeping and composting programs, in addition to growing and recording data about moss.
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, one day, it was very hot and the earth was very dry. Concerned that no rain was coming, Moko set out to find a man believed to be a wizard. The man told him to follow the path of the dunes, which would take him to a sea of sand. Moko walked for a long time. Suddenly a strange shape appeared in the distance. It resembled trees surrounding a small pond. But a few steps later he couldn't see it anymore. It had vanished into the immensity of the desert. Moko scanned the horizon again. He turned full circle and once again saw the pretty pond and surrounding trees. He walked toward it slowly, never taking his eyes off it, his heart pounding. This time he reached the edge of the small oasis, relaxed in its freshness and drank.
