The world's nuclear power plants have generated an estimated 300,000 tons of high-level radioactive waste that must be safely stored for 100,000 years or more. Every year, they generate another 12,000 metric tons of high-level waste. Takes viewers deep into the Onkalo facility as it is being constructed and asks Onkalo representatives, scientists, theologians and others to address fundamental but challenging questions.
Did you know Oregon crab fishers lose their pots because they often encounter high winds and waves up to 40 feet? Join Joel on this adventurous quest as he boards a vessel to sail the Oregon coast in search of crab pots in an effort to help clean up the ocean. Part of the Curiosity Quest Series.
In this chapter, the scientists will try to find the best corn to make the biggest popcorn. They will also have a lot of fun with optical illusions. And finally they will show how eyeglasses gather light by using lasers. Part of the House of Science Series.
Professor Kaos has invented a machine that allows cows to produce chocolate milk. After seeing the chocolate milk-producing cows, Olli senses something is wrong. The children are left to wonder if the invention causes more problems than it solves? They help Professor Kaos realize that his invention is hurting the cows. Part of the "My Little Planet" series.
This episode features the development of a new camera that detects cancer. Its design is based on the structure of a butterfly's eye. Scientists are also experimenting with ominphobic materials that repel dirt. Studies also reveal that animals are beginning to recolonize ecosystems that were once prime hunting grounds for them. Part of the "4 Awesome Discoveries You Probably Didn't Hear About This Week" series.
In a decade dominated by the Great Depression, the inventors of the 1930s were desperately trying to make a living. They come up with some simple yet ingenious inventions that are still practical necessities in our fast-paced life. Featured inventions include: the helicopter, xerography, the parking meter, the walkie talkie, and the electric guitar.
It’s a freezing cold day inside the National Ice Core Laboratory (NICL) in Denver, Colorado. That’s because the NICL is a facility for storing and studying ice cores recovered from the polar regions of the world. And, saws are buzzing, as scientists from all over the U.S. are measuring and cutting pieces of precious Antarctic glacier ice to take back to their labs for research. Part of the National Science Foundation Series “Science Nation.”
Hidden in a vault outside Paris, vacuum-sealed under three bell jars, sits a palm-sized metal cylinder known as “Le Grand K.” Forged in 1879 from an alloy of platinum and iridium, it was hailed as the perfect kilogram—the gold standard by which other kilograms would be judged. However, it is wasting away, and scientists are scrambling for a more reliable standard. Part of the "Uno Dos of Trace" series.
Chemistry experiments demonstrate four distinct ways to separate chemical mixtures: filtration, crystallization, distillation, and sublimation.
When Geologist Jeff Donnelly of the Woods Hole Oceanographic Institution (WHOI) hunts for hurricanes, he does it safely at ground level, or just slightly below. He is even able to do it without having to encounter so much as a drop of rain or a gust of wind. With funding from the National Science Foundation, Donnelly leads a team that studies long term global hurricane patterns. They’ve unearthed some interesting findings about past hurricane activity which might provide a hint about what to expect in the future.
Travels to over a dozen locations exploring the state of global fisheries. Explores the consequences in the Indian Ocean of nets with mesh so fine that even seawater only trickles out, the potential extinction of tuna in the Mediterranean and the North Atlantic, and the impact of land-based sources of pollution on coastal fishing areas. Part two of this series reports on the search for solutions.
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."
The sense of touch is an invisible force of human nature. Today, touch is undergoing a revolution. Science has pushed the limits of nature thanks to technological touch. It is now possible to touch objects virtually that are invisible or located thousands of kilometers away. A simple movement in the air is enough to control them. Medical technology has even succeeded in giving a sense of touch to bionic limbs made of metal, plastic, wires, and processors. Slowly but surely, prostheses are starting to perform better than natural limbs. Part of the “Human + The Future of Our Senses” series.
More than two and a half miles below the ocean's surface, the wreckage of the Titanic rests on the seafloor. The legend of the Titanic was larger than her size, and finding the wreck site opened a door to not only exploration and scientific study, but to salvage as well. The United States negotiated an international agreement with representatives of the United Kingdom, Canada, and France. This agreement recognizes the wreck site as a memorial to those who died and a wreck of great archaeological, historical, and cultural importance.
What would you think of powering a car using a water fuel cell, a home furnace powered by permanent magnets, or a self-driven electromagnetic engine with enough power to put a spacecraft into orbit? This is all energy that humans wouldn't have to pay for and that wouldn't pollute the earth. Not only would free energy change the world, but it would end human dependence on having to use so much of the world's fossil fuels.
With support from the National Science Foundation, Center Director Doug Keszler and his team in the College of Science at Oregon State University are developing the next generation of electronic circuits, starting with the basic computer chip. In the manufacturing process, they want to replace bulky carbon compounds with metal oxides, in order to put more transistors onto a chip. The new process would be cleaner, faster and cheaper. Part of the National Science Foundation Series “Science Nation.”

Dysprosium is a chemical element with the symbol Dy and atomic number 66. It is a rare-earth element with a metallic silver luster.
Some chemical reactions happen spontaneously, like metal rusting. Other reactions are non-spontaneous and need to absorb energy in order to occur. Using the Second Law of Thermodynamics, the principle of entropy, and the calculation of Gibbs free energy, scientists can predict which reactions will occur and vary the conditions to make more of the desired products. In equilibrium reactions, both products and reactants are always present. Equilibrium reactions in the human body are essential for life and can be exploited in chemical manufacturing as well. Part of the series Chemistry: Challenges And Solutions.
