  • Closeup view of very thin wires forming concentric squares and other geometric patterns. Caption: these circuits are thinner than a hair

    Imagine if there were electronics able to prevent epileptic seizures before they happen, or electronics that could be placed on the surface of a beating heart to monitor its functions. The problem is that such devices are a tough fit. Body tissue is soft and pliable while conventional circuits can be hard and brittle--at least until now. Materials scientist John Rogers at the University of Illinois Urbana-Champaign is working to develop elastic electronics.

  • Industrial plant with plumes of smoke billowing into the sky from exhaust pipes. Caption: These people put pressure on the ecosystem by pollution

    Some conservationists believe that perhaps half of all species on earth will become extinct in the next 50 to 100 years. To prevent that, several groups work to assist efforts at conserving biodiversity. Some of the efforts include taxonomy (cataloging species), managed retreat (letting nature retake areas), saving seeds, and propagating endangered plants. Man's efforts toward destruction and development must be balanced with sustainability.

  • Illustration of nerve cells and the connections between them. Caption: It targets the brain's reward system

    Peoples’ attitudes about marijuana have changed dramatically over the years, but one thing is certain--marijuana changes the way the brain functions. The THC in marijuana enters the lungs, is absorbed into the bloodstream, and enters the brain almost immediately. Viewers will understand the immediate effects of marijuana use on various body systems. This program also discusses the effects of marijuana on attention, memory, and learning. Part of the "Talk It Out" series.

  • Wolf in natural habitat. Caption: allowing steady pursuit of prey over long distances.

    Predators play a fundamental role in maintaining the health of ecosystems. Research strongly supports the contributions of wolves in particular to the functioning and stability of the overall landscape. Students will learn about conservation methods to reintroduce and protect wolves in the wild. Part of the "Saving a Species" series.

  • Sea slug crawling on the sea floor. Caption: in the nervous systems of slugs and other animals.

    While the human brain and nervous system are wired with hundreds of billions of nerve cells, or neurons, sea slugs can get by with tens of thousands. Ironically, sea slugs reveal a lot about the chemistry of the human brain and nervous system. In fact, they are ideal as study subjects for research on learning, memory, and how neurons control behavior. With support from the National Science Foundation, analytical chemist Jonathan Sweedler and his team at the University of Illinois are working to develop new measurement tools that enable insights into the function of individual cells in the central nervous systems of slugs and other animals in order to uncover novel neurochemical pathways. Part of the National Science Foundation Series “Science Nation.”

  • Person with a device attached to their head behind and above their ear and a wire leading to a device that is affixed to the back of their ear. Caption: It's called a cochlear implant, and it helps me hear.

    The cochlear implant is widely considered to be the most successful neural prosthetic on the market. The implant, which helps individuals who are deaf perceive sound, translates auditory information into electrical signals that go directly to the brain, bypassing cells that don't serve this function as they should because they are damaged. Led by engineer Pamela Bhatti at the Georgia Institute of Technology, a team of researchers at both Georgia Tech and the Georgia Regents University created a new type of interface between the device and the brain that could dramatically improve the sound quality of the next generation of implants.

  • Grocery store produce department with stacks of different fruit. Caption: Many fruits are better for us than candy and cookies.

    In the top story, Katie speaks with a group of teens who are raising money for Save the Children. Save the Children is an organization that helps kids around the world by providing food, shelter, medicine, and a brighter future. Eden debunks some common health advice. She gets the facts on: going outside with wet hair, how long gum stays in your stomach, whether or not milk actually helps people sleep, and if scaring someone is an effective cure for hiccups. Magdalene reports on the internal navigation of humpbacked whales. Scientists have found that humpbacked whales can do a thousand-mile trip in almost a perfectly straight line. Other segments include the history behind Florida's state flag and the Vietnam Memorial in Washington, D.C. Part of the "Teen Kids News" series.

  • A map titled, Uso de la Tierra. The region depicted is divided into three segments. The larger segment is labeled, Cuenca. The group of smaller regio is labeled, Agricultura. The remaining region in between the first two regions is labeled, Bosque. Spanish Caption: Una oportunidad de crear planes de trabajo a largo plazo.

    This video describes how indigenous communities from the tropical rainforest of Darién, Panama, use drones to map their lands. The communities use these maps to protect their territories from outside incursions and to design sustainable land-use plans. The Darién Gap is a remote tropical forest that has been home to indigenous people for thousands of years. As pressures from outside human development encroach on the forest, these communities are protecting their land using a cutting-edge tool: drones. Through a partnership with a nonprofit organization, the Rainforest Foundation, they map their community boundaries to secure land titles, create sustainable land-use plans, and monitor their forests against logging and ranching.

  • Small, furry animal with a pointed head and nose. Caption: meerkats emerge just after sunrise.

    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.

  • Person pointing at fabric. Caption: Try these biomedical textiles on for size.

    Engineers are joining forces with designers, scientists, and doctors at Drexel University to produce new biomedical textiles, and the resulting smart clothes are not only fashionably functional, but could also be life savers. With support from the National Science Foundation (NSF), electrical and computer engineer Kapil Dandekar, industrial and fashion designer Genevieve Dion, and OB-GYN Owen Montgomery are incorporating RFID technology into their “belly bands” for women with high-risk pregnancies. The band continuously tracks data and alerts the doctor’s office via the Internet should the woman start contractions. Part of the National Science Foundation Series “Science Nation.”

  • Small boats with people on the water at sunset. Caption: This way of life has been around for a long time.

    The second in a series of documentaries is built around a custom that is thousands of years old: fishing. At present, about 65 million people in the Greater Mekong live directly from the fish the river has to offer. Fishing methods are of course different according to places and ethnic groups. Additionally, modern times strongly challenge the fishermen in the Greater Mekong. Torn between tradition and modernity, these men and women have to make for themselves, and their families, decisions about new ways of life. Climate change and pollution add to the problem of a painful adaptation to a new way of life. Series: The Soul of Southeast Asia

  • Illustration of human torso with area over the upper chest in x-ray vision, showing the rib cage and heart. Caption: the heart.

    Students receive a crash course in the physiology and functioning of their hearts as well as how to keep their hearts healthy. Animations clarify how the heart works to provide oxygen and nutrients to all the tissues and organs of the body. They also detail what can go wrong. The program stresses that even teenagers can show early signs of atherosclerosis and other heart problems. Two cardiologists and a dietitian then pinpoint the main risk factors for an unhealthy heart, including: smoking, abnormal levels of cholesterol, high blood pressure, obesity, diabetes, and physical inactivity.

  • Closely spaced plants growing toward the water's surface. Caption: They grow in dense groupings, much like a forest on land.

    Kelp forests can be seen along much of the West Coast of North America. NOAA scientists study kelp forests by visiting the same locations over and over to assess the presence and abundance of a variety of organisms. Monitoring allows marine scientists to determine if the kelp forest is changing over time and to identify the cause of those changes, whether natural or human. Healthy kelp forests maintain the existence of thousands of plants, animals, and fish stocks. All of these require a thriving ocean ecosystem.
