Access to safe drinking water is a global problem for nearly a billion people. For approximately 200 million people, many in Africa, high levels of naturally occurring fluoride in the water cause disfiguring and debilitating dental and skeletal disease. University of Oklahoma environmental scientist Laura Brunson is back from Ethiopia where, with support from the National Science Foundation, she’s developing fluoride filtering devices that use inexpensive materials readily available right there in the villages.

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.
Many outlet glaciers in Greenland feed ice from the land into fjords, where discharge of icebergs and melting of the glaciers by warmer ocean waters contribute to rising sea levels. David Holland of NYU studies what happens in the fjord when ice meets water. He also studies how the dynamics at the margin between ice and sea are changing, and what those changes could mean in the future for global sea level rise. Part of the National Science Foundation Series “Science Nation.”
For millennia, hurricanes have threatened the Eastern United States, the Caribbean, and parts of Latin America. But changes to global climate have serious consequences for the future. For example, rising sea-levels mean that storm surge from hurricanes will impact ever further inland. In episode three, specialists discuss why they believe that hurricanes will become less frequent but increasingly powerful. Insight and interviews from leading experts such as Nobel Prize-winning climatologist, Jean-Pascal Van Ypersele, explore the preparations needed to withstand a super storm. Part of the "Hurricane, the Anatomy" series.
Sand particles from the Sahara desert have long been known to travel across the Atlantic Ocean and southward to the Amazon rain forest. These accumulations are known as dust carpets, and they form as water molecules adhere to the sand particles. As water and sand adheres to one another, they form droplets that accumulate into clouds. However, the Mongolian desert dust carpets present problems for ecosystems upon which it falls. This program explores the science behind the storms and their impact on global climate.
Goes in search of sustainable solutions. In the Canary Islands, fishermen use rod and line for a valuable species and only take fully mature fish. In Oman, the authorities will only allow fishermen to use one kind of boat and net, and they strictly monitor the catches. Leading decision-makers describe how drastic action must be taken to protect wild stocks and ecosystems, but almost nowhere are measures being taken that help alleviate the crisis. Part one of this series explores the state of global fisheries.
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.
One day, microbes will eliminate dirt and garbage, filter exhaust systems, and help make self-cleaning clothing possible. Takes viewers on a global journey-from the U.S. to Iceland, Sweden, India, China, Senegal, and Australia-to meet the world's leading specialists in bacteriology and to discover the incredible abilities of the microscopic life-forms they study. Employs state-of-the-art imaging technology and animation to illustrate how bacteria have learned to adapt to harsh environments and how they can be found in a vast array of human-made products and materials, including medicines, pesticides, plastics, solvents, and even electroacoustic speakers.
NOAA's environmental satellites provide data from space to monitor Earth to analyze coastal waters, relay life-saving emergency beacons, and predict and track tropical storms and hurricanes. NOAA operates three types of satellite systems for the United States: polar-orbiting satellites, geostationary satellites, and deep space satellites. Polar-orbiting satellites circle Earth and provide global information from 540 miles above Earth. Geostationary satellites constantly monitor the Western Hemisphere from around 22,240 miles above Earth. The deep space satellites orbit one million miles from Earth, providing space weather alerts and forecasts while also monitoring the amounts of solar energy absorbed by Earth every day.
The National Science Foundation in cooperation with the Marinette Marine Corporation (MMC) and the University of Alaska, Fairbanks has successfully launched the R/V Sikuliaq, a next-generation global class research vessel. MMC is the Wisconsin shipyard that built the ship, with funding provided by NSF through the American Recovery and Reinvestment Act of 2009. UAF's School of Fisheries and Ocean Sciences will operate the ship as part of the U.S. academic research fleet. The new vessel's name, Sikuliaq, pronounced “see-KOO-lee-ack,” is an Inupiat word meaning young sea ice. Part of the National Science Foundation Series “Science Nation.”
RoboCup is the Olympics of college-level robotics and artificial intelligence contests. As teams gear up for the next round of competition, the “SpelBots” have positioned themselves as the team to beat. That’s the team from Spelman College, a historically black liberal arts college for women in Atlanta. They tied for first place globally in the humanoid soccer championship in Osaka, Japan in 2009, just four year after becoming the first all-women, African American team to enter the competition.
By providing a big picture view of food and globalization, viewers examine the connections between food, environment, health, and communities. Viewers also learn specific steps that can be taken to create a sustainable food future.
