Anna has built a successful business from the ground up, and upon retirement, she leaves the company to her employees, not to her son. What does that decision tell us about Anna's psychology and about the development of the human brain over a lifetime? Explores the emotional and neurological elements of learning, explaining how the brain processes and stores experiences and prepares for future decision-making. Employing real-to-life dramatizations, Anna's journey from innocent teenager to philosophical retiree--and the changes that take place in her cortex, hippocampus, and neural synapses as she faces and overcomes challenges--are all depicted. In addition, several influential brain experiments from the past decade are described.
Carbon is the basis of all organic molecules. It is also one of the most abundant elements in the universe. This video segment illustrates the special characteristics of carbon that make it an essential ingredient for life.
Hydrothermal vents were originally discovered near the Galapagos Rift in 1977. They form from hot springs produced by underwater volcanoes or tectonic activity. Scientists have found an abundance and assortment of life that has adapted to the harsh, dark conditions surrounding these seafloor vents. Part of the "Deep Sea Dive" series.
Provides insights on extraterrestrial life from scholars and astronomers at premier research institutions, such as the Harvard-Smithsonian Center for Astrophysics and NASA. Shows how proponents of the "aliens are here" theories have compiled a library of books, Internet sites, and documentaries to support their ideas. Includes an interview with Budd Hopkins, author of several alien abduction books, and a hypnosis session of a young man who recalls encountering alien creatures. Also includes a demonstration by an illusionist who shows that hypnosis is nothing more than tricking the mind.
What happens when a whale dies? This short piece explores the concept of decay, and the role decay plays in giving life to other organisms.
At the twilight of an active life, Anna is now bedridden due to a serious fall. What makes the elderly--even those who are in full possession of their mental and physical faculties--more prone to falling than younger people? As this program demonstrates, the answer lies not in the body or the brain alone, but in their interconnection. Exploring Anna's past dreams of becoming a ballerina, the film shows how complex physical motion, such as dancing or even typing, requires sophisticated coordination between the body's neural, muscular, and skeletal systems. How aging affects such coordination and how new artificial limb technology enables movement are running themes in the program.
With support from the National Science Foundation (NSF) and National Aeronautics and Space Administration (NASA), Georgia Tech biochemist Nicholas Hud and a team at the Center for Chemical Evolution (CCE) are working to chip away at how life on earth began. They are homing in on how chain-like chemicals called polymers first came together and evolved three-and-a-half to four billion years ago. Part of the National Science Foundation Series “Science Nation.”
Anna was born with a sweet tooth, and as a young woman, she created a successful business using it. Her delicious jams and jellies gave pleasure to many, but did they also cause harm? Explores the way the human body processes food and how its long-term growth and development are shaped by eating habits. Illustrating cellular aging and its relationship to AGEs, or advanced glycation end products, a connection is drawn between the bacteria an infant must consume to build a healthy immune system and the bacteria that consume the body at death. As Anna's life draws to a close, viewers will understand that "dust to dust" is a cycle in which humans take an active part--every time they sit down to a meal.
Shows the structure, behavior, and life cycles of planarians and their free-living relatives (class Turbellaria). Illustrates the bizarre life cycles of flukes (class Trematoda) and tapeworms (class Cestoda) with detailed animations and revealing images of these parasites in action.
This animated short tells the story of Alfred Wegener, a German astronomer and atmospheric scientist, who came up with the idea that continents once formed a single landmass and had drifted apart. Continental drift explained why continents' shapes fit together like pieces of a puzzle and why distant continents had the same fossils. During Wegener’s time, the idea was met with hostility but after his death a large body of evidence showed that continents do indeed move. Today the theory of plate tectonics is a fundamental principle in geology.
When Brandon was 10 he was diagnosed with psoriasis. At first, he was very ashamed due to the visible patches on his skin. However, five years after his diagnosis, with adequate treatment, he lives with the disease and has a normal life.
Ten 10-minute programs explore temperate and tropical habitats and their abundant diversity of life. Tape one: compares temperate and tropical forests, their habitats, the effects of rain on them, and shows how size can generate great diversity. Tape two: uses butterflies to represent species diversity, compares how people relate to temperate and tropical environments, explores humans' impact on diversity, and investigates issues of threatened and endangered species.
Scientists are conducting land surveys in the Southern Appalachians to determine just how healthy the land and water is. In their research, they discover that the smallest creature living in the area, the salamander, provides the most information and are important to the health of the ecosystem.
The American Museum of Natural History has more than 33 million artifacts and specimens in their scientific collections. This episode provides an overview of the various objects found in the museum. Some are centuries-old specimens, while others are entirely new types of specialized exhibits. However, the entire collection is an irreplaceable record of life on Earth. Part of the "Shelf Life" series.
Functional electrical stimulation technology (FES) is designed to interface technology with muscles and nerves in an attempt to restore some level of function for people with central nervous system disabilities. Visits several experimental programs that are using implanted electrodes, controlled by external computer devices, to enable people with spinal cord injuries to stand, transfer, and, under controlled conditions, even walk.
Biologist Bill Elliot takes a small group of scientist cave exploring. They capture and describe the different creatures that live their lives underground. Elliott and his group are able to shed light on the mysterious life of the underworld. Segment of video from Wild Chronicles Series.
Global warming is changing the intensity, duration, and frequency of precipitation. These changing climate patterns are altering the water cycle and negatively impacting the environment. As the climate of regions changes, life on earth is significantly impacted. The increased potential for flooding raises concerns over loss of life and property, and individual actions are critical to lessen global warming and climate change. Chapter 4 of Air: Climate Change Series.
Explains why the body needs regular supplies of air and how these get to the body. The camera follows the process of breathing through the ultra-thin membrane of the lung into the blood, showing how the varying demand for oxygen is met by the exchange of information between the brain and the chest muscles and how the body rids itself of carbon dioxide.
Six researchers share 60-second stories about organisms that may be gone, but not forgotten. Researchers and scientists study these stories to get a better understanding of the complexities of life on Earth. Part of the "Shelf Life" series.
