With support from the National Science Foundation, computer scientists at the University of Illinois at Chicago are pushing science fiction closer to reality. They have created a wraparound virtual world in which a researcher wearing 3D glasses can take a walk through a human brain, fly over the surface of Mars, and more. In the system, known as CAVE2, an 8-foot-high screen encircles the viewer 320 degrees. A panorama of images springs from display panels, conveying a sense of being able to touch what's not really there. Part of the National Science Foundation Series “Science Nation.”

Climb aboard the Cyclops, a microscopic research vessel, and investigate an amazing hidden world on which all living things depend. The Cyclops houses a team of scientists known as the Micronauts and guides them through their discoveries of biological classification, diversity, and ecology. While navigating the dense aquatic weed forest of the pond, the Cyclops is pulled off course by a hydra. After escaping its tentacles, the crew begins to study how the hydra reproduces, captures its food, and digests its prey. One of the Micronauts takes a journey inside the hydra’s digestive system to get a first-hand account of the digestive process. Part 4 of the Microscopic Monsters Series.
Volcanoes are a part of the earth, and they have intrigued people for hundreds of years. Scientists study the earth's plates in order to understand the complexity of volcanic activity around the world. They also study different types of lava, rocks, and the gases that have dissolved into rocks. In the past, studying volcanic activity was extremely dangerous for scientists. Now they have access to tools, such as global positioning systems and seismometers, to help in predicting volcanic activity.
As shown on the History Channel. Gold dates from the time of the supernova explosion that gave birth to the building blocks of our solar system. When it was created, the Earth included a tiny percentage of gold atoms, and over the aeons geologic processes have concentrated it into various nooks and crannies around the globe. The best of it is in the ancient Precambrian rocks in South Africa, where the deepest mines in the world extract it. In other regions of the world, gold can be gathered from younger sedimentary rocks that have been eroded off older Precambrian rocks. The American gold rush was this type of deposit. Now in Nevada, sedimentary rocks are leached on a truly vast scale to extract the gold.
Takes viewers to an inner city high school where students had serious discipline and learning problems. More than half of the eighth and ninth grade students here were diagnosed with ADHD, and many worked at fourth grade level. The teacher, Allison Cameron, discovered the groundbreaking research by the Harvard Professor of Psychiatry, John J. Ratey, M.D. (author of "Spark: The Revolutionary New Science of Exercise and the Brain"), showing a link between sustained aerobic activity and the brain's ability to grow new cells. Allison also learned that Napierville High School in the Chicago area, which began exercise programs 18 years ago, has one of the best academic records in the U.S.
The ancient city of Rome wasn't built in a day, but now that city, along with all its famous landmarks, can be digitized in just a matter of hours. A new computer program under development at the University of Washington in Seattle combs through hundreds of thousands of tourist photos on Flickr and other photo sharing sites and reconstructs the city – pixel by pixel. Now, viewers can fly around many of Rome's famous landmarks on their computer in far more detail than they'd ever be able to on current virtual map programs such as Google Earth. The new technique may one day create online maps that offer viewers a virtual-reality experience. The software could build cities for video games automatically, instead of doing so by hand.
Teachers often say to students, “Put your thinking caps on,” and one day, students might just do that for real. Vanderbilt University psychologist Geoffrey Woodman says that’s because scientists are being equipped with more and more tools they can use to better understand the brain, and now, they can even eavesdrop on individual neurons. Initial support from the National Science Foundation (NSF) allowed Woodman and his team at the Vanderbilt University Visual Cognitive Neuroscience Laboratory to study memory and perception. Then, the researchers tested their theory that electrical stimulation of the medial frontal cortex can boost learning and improve decision-making.

As scientists discovered more and more chemical elements, they began developing systems to organize the elements by their chemical properties, leading to the modern periodic table. Through its organization, the periodic table makes clear the underlying chemical and physical trends among the elements. The periodic table is being continually updated even today as scientists strive to create new elements in laboratories. Part of the series Chemistry: Challenges And Solutions.

Also stars Billy Bob Thornton, Kathy Bates, Jeffery Tambor, Jesse "The Body" Ventura, Raymond Cruz, Weird Al Yankovic, Vincent Schiavelli, and Pat Morita.
Mai Lee Chang did not envision becoming a NASA engineer. At the age of six, her family settled in the U.S. as refugees of the Vietnam War. During her senior year in high school, her physics teacher suggested that she look into engineering as a potential college major. Mai Lee is an engineer at the Johnson Space Center within the Human Systems Engineering and Development Division. She started her career at NASA as a co-op student. Part of the "Women@NASA" series.
The Center for Advanced Forestry Systems is using forestry science and collaborations among universities, industry, and the government to make commercially grown forests more productive and sustainable. With support from the National Science Foundation (NSF), research teams at Virginia Tech, North Carolina State University, and the University of Washington have teamed up through the center to study how new slow-release fertilizers could improve growth and not destroy waterways.

The researchers are building scaffolds that mimic the three dimensional structure of human tissue. They use a machine called a biofabricator to deposit cancer cells at strategic locations inside the 3D structures, just like tumors in human flesh. These structures are high fidelity test systems. Burg and her team can culture cancer cells in them, experimenting to see which treatments are the most effective, with the ultimate goal of personalizing a treatment or a vaccine for individual patients. Part of the National Science Foundation Series “Science Nation.”

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.
Part of the "Gunther's ER" series. The human brain suffers irreversible damage if deprived of oxygen for even a few minutes-a fact Dr. Gunther von Hagens demonstrates by utilizing human cadavers as examples. Simulating an artery injury to illustrate oxygen depletion through blood loss, von Hagens then focuses on problems affecting the trachea, the top priority for ER doctors. In order to show the major structures of the airway and how they can be blocked by foreign objects, von Hagens inserts an endoscope into his own throat and saws a frozen body's throat in half, revealing the major structures of the airway and their potential weaknesses. Red Cross first-aid expert Emma Rand explains simple techniques for clearing the airway, while emergency medicine consultant Dr. John Heyworth shows how paramedics treat complex trachea damage. NOTE: Viewer discretion is advised. Contains clinically explicit language and nudity.
With support from the National Science Foundation, computer scientist Shwetak Patel and his team at the University of Washington are developing new sensing systems to empower people to make better-informed decisions for themselves and their homes. Patel's initial interest was in providing the most detailed information yet for consumers about their energy and water consumption, and most of that technology has already been transferred to the marketplace. Part of the "Science Nation" series.
Space weather can have important consequences for everyday life, such as interference with radio communication, GPS systems, electric power grids, the operation and orientation of satellites, oil and gas drilling, and even air travel as high altitude pilots and astronauts can be subjected to enhanced levels of radiation. The United States Geological Survey (USGS) Geomagnetism Program monitors variations in the Earth's magnetic field through a network of 14 ground-based observatories around the United States and its territories, providing data in real-time to a variety of customers.
