Part of "Show Me Science" series. Are animals intelligent? Bees communicate with each other. Monkeys use rocks and sticks to help them get food. Is this instinctual or is it evidence of thought? Some scientists believe that one measure of intelligence is self-awareness, and that an animal's reaction to its own image in a mirror can tell us whether or not it is self-aware. Looks at fish, birds, monkeys, and primates and their reactions to themselves in a mirror. Researchers look for signs of self-recognition as they observe, record, and interpret the reactions of these animals. Includes suggestions for careers in this field of study.

When a tsunami hits, it may come ashore like a fast rising flood and strike with devastating force. The series of waves may continue for hours. Sometimes the first one may not be the last or the largest. Potential warning signs of an incoming tsunami include a strong earthquake that causes difficulty standing, a rapid rise or fall of the water along the coast, and a loud ocean roar. Part of the "Danger Zone" series.
In this episode, researchers discuss the novel applications for a self-healing reverse filter. For example, researchers are studying its application in unsanitary environments. Scientists also ask the question: Is laziness a fruitful strategy for the survival for some species? Researchers are studying the link between metabolic rate and extinction. In the final segment, weather forecasts are predicting that El Niño and La Niña are likely to intensify wildfires and increase drought risk. Part of the "4 Awesome Discoveries You Probably Didn't Hear About This Week" series.
Stuart Rowan, a professor at Case Western Reserve University, has created polymers that are able to self-heal when heat is applied using a special light. Part of the Fast Draw Series.
Explains what is normal for boys and girls at puberty: the biological facts of physical maturation, the timeline for growth for both sexes, the normal feelings of self-consciousness, the need for good personal hygiene, why mood swings happen, and preparation of the body for human sexuality and reproduction.
Host Alex Dainis highlights the uses and history of parafilm. It is commonly used in health care, pharmaceutical, and research laboratories for covering or sealing vessels such as flasks, cuvettes, test tubes, beakers, Petri dishes, and more. Scientists and researchers use it in the lab since it is ductile, malleable, nontoxic, and self-sealing.
Nourish is an educational initiative designed to open a meaningful conversation about food and sustainability, particularly in schools and communities. In this clip, health food advocate Anna Lappé explains how farmers use practices that are sustainable and protect the environment. Part of the Nourish Short Films Series.
Features both male and female students discussing how hormones trigger the new social and emotional changes experienced during puberty. Covers self-esteem, body image, conflicts with parents, desire for independence, development of romantic feelings, bullying, and the need to treat each other with respect.
Self-taught scientists and engineers, Wilbur and Orville Wright taught the world how to fly and are one of America’s greatest success stories. Their first successful flight, on North Carolina's Outer Banks, took place in December 1903. Next, they returned to Dayton, Ohio and continued to develop and test the world's first practical airplane.
Sharks have been swimming the ocean for 400 million years. But today, many species of sharks are in deep decline due to overfishing and shark finning. A healthy ocean needs sharks. Thankfully awareness of their importance is growing. Part of the "Endangered Ocean" series.
Mining traditionally has destroyed vegetation and topsoil as it takes minerals from the ground. New techniques and increased environmental awareness has recently led to new land reclamation experiments. Adding earthworms and bacteria to restore the land is one such venture. Highlights bioremediation--using living organisms-- to clean up heavy metals left as mining residue.
This program from the acclaimed PBS Nature series, "Forces of the Wild," looks at man's constant attempt to adapt the Earth to his own needs without concern of the consequences. Earth is a self-regulating organism full of forces impossible to control. Water is one force, creating life where there is none and destroying life when it can't be tamed. Narrated by James Earl Jones.
The body is like a self-supporting hospital, able to deal with its own with wounds, bacterial invasions, fractures, and obstructions to its various passages. Follows the sequence of events over seconds and weeks when skin or bone is damaged, and shows the defensive reactions of blood clotting, fever, and mending of bone fractures.
Part of being an active citizen is taking care of the environment. In this episode, students learn all about the history of the environmental movement in the United States and the origins of the holiday known as Earth Day. Part of the "Constitution Hall Pass."
An expert on exercise physiology discusses the importance of different elements of fitness, and teenagers share personal stories about how exercise helped them achieve and maintain a healthy weight. Exercise also helps build strength, develop endurance, improve agility, boost self-confidence, and connect socially. John Ratey, a professor of psychiatry, describes the growing evidence that aerobic exercise remodels our brains, making us sharper mentally, and providing protection against mood disorders. Teens describe how exercise helped them deal with depression, anxiety, and stress.
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.
While it is relatively straightforward to build a box on the macroscale, it is much more challenging at smaller micro and nanometer length scales. At those sizes, 3D structures are too small to be assembled by any machine and they must be guided to assemble on their own. With support from the National Science Foundation, Brown University mathematician Govind Menon and Johns Hopkins University chemical and biomolecular engineer David Gracias are developing self-assembling 3-D micro and nanostructures which can be used in a number of applications, including medicine.
Meet Boss – the car that can drive itself. Boss is the invention of Carnegie Mellon researcher Raj Rajkumar and his team. It has 18 sensors, including a three dimensional laser and onboard computers that connect to GPS and mapping software. When it comes to knowing the rules of the road, Boss rarely makes a mistake. With support from the National Science Foundation, it was built for a Department of Defense competition called the DARPA Urban Challenge. Boss negotiated the roads, including traffic, and was the hands down winner in 2007.
Throughout the world, innovative thinkers and entrepreneurs are transforming their communities, making the dream of sustainable living a reality. The United Kingdom's push for sustainable housing developments raises awareness of energy efficiency and promotes eco-friendly home design. Cement alternatives developed in Australia reduce the carbon footprint for concrete production by 60%. Two industrial designers from Colombia are creating fashion items from recycled tires. In the Philippines, the inventor of coconut fiber nets shows how his company helps prevent devastating mudslides in the region and provides employment to locals.
