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.

Documents efforts to contact and communicate with potential extraterrestrial life and interstellar space. Attempts to answer the question: Are we alone? Looks at the Drake equation, the standard for anyone seeking to find the number of planets with intelligent life in the Milky Way galaxy. Discusses the pioneering research at the Search for Extraterrestrial Intelligence Institute (SETI) based in Mountain View, California.
Millions of years ago, a group of bacteria, the cyanobacteria, developed a new way to harness energy from the sun. This new development had important consequences for the evolution of both the atmosphere and the diversity of life on Earth.
This video explores the fascinating world of microscopic life. It begins by discussing viruses and explaining how they cause disease. Students also learn the importance of bacterial cells and explore the life of protists. Additional concepts and terminology include microscope, vaccine, moneran, decomposition, amoeba, phytoplankton, yeast, algae, paramecium, and protozoa.
Living things go through changes in the course of their lives, referred to as life cycles. This program explains the life cycles of living organisms, specifically focusing on plants and animals. Video footage and colorful animations illustrate how living things change. Important terminology includes egg, seed, growth, metamorphosis, germination, stage, larva, pupa, nymph, and adult.
It was once believed that organic compounds, light, and water were needed to sustain life, but life has been found in complete darkness underwater. National Geographic Explorer Bob Ballard discovered Lost City, an underwater mountain range, and it is teaming with life. Segment of a video from Wild Chronicles Series.
Oyster reefs protect shorelines from erosion, create fish habitats, and clean the water. Scientists in North Carolina are working to restore the oyster reefs along the coast.
Updates the five kingdoms classification scheme with the latest understanding of life's organization based on DNA, fossil, and biochemical evidence, reorganizing all life into three great branches: Archaea, Bacteria, and Eucarya. Shows concise animations and superb microscope footage of primitive cells.
From fossil evidence, it appears that life may have existed on Earth as early as 3.5 billion years ago. This suggests that life must have evolved sometime during Earth's tumultuous first billion years. How did life evolve? What did early forms of life look like? Topics covered include protocells, endosymbiosis, prokaryotes, eukaryotes, evolution, heredity, variation, natural selection, genetic drift, and gene flow. Part of the "Biology" series.
All living organisms share several key characteristics or functions. When combined, these characteristics serve to define life. In this episode, Petunia and Pinky discuss several of the characteristics of life. Part of "The Amoeba Sisters" series. Please note: This title contains discussions on sexual reproduction.
Where do baby animals come from? What do they look like? A family visits a farm in spring and learns the answers. Shows a duckling hatch and a lamb and calf being born. Viewers decide which creatures are born from eggs and which are born live. Later that spring, the family has a new baby.
Students explore the life cycle of plants. This video discusses the process of plant development from a small seed to a mature plant.
Scientists investigate the microbes found in Yellowstone National Park hot springs, geysers, and other pools of water. Micro life is thriving in the extreme environments of the hot springs, and microbiologists believe the diversity of life found at Yellowstone will aid in studying life beyond our planet. Segment of video from Wild Chronicles Series.
Part of the "Inside the Living Cell" series. Provides an overview of the different kinds of cells, emphasizing the fact that all cells have a common organizational structure and carry out similar biochemical processes. Presents the discovery of cells, cell structures, organelle function, cell varieties, and the chemistry of life.
Part of the animated "Johan, the Young Scientist" series. Housebound during a rainy day, Johan goes to ScienScape where it also rains. Johan, Ani, and Moki set out to find where the rainwater ends up. This leads them from gutters to drains to rivers. They soon learn that all living beings need water to survive.
Shows the metamorphosis of the mosquito from a water ecosystem organism to a land ecosystem organism. One of nine segments in a series, with all nine available on a DVD.
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.
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.
