More than 70 underwater canyons exist off the northeastern coast of the United States, and some are more than three miles deep. In this video, journey to some of the deep canyons and discover new species of sea coral through the eye of a remotely operated vehicle (ROV).

Genes, those traits passed down to us by our parents, are the things that make each of us different from the others. This question-answer format covers basic information about genes, chromosomes, cell division, dominant and recessive genes, and fertilization. Illustrates Mendel's rules of heredity. Covers advances in the fields of DNA, genetic engineering, and gene therapy. Reviews major points.
The sun's powerful, warm rays light up the sky with brilliant color and heat. The changing cycles of the sun can affect the earth and its living organisms. The sun is similar to a living organism-just as humans are born, grow older, and die, so too will the sun. When this happens, the rest of the solar system will have no future.
Biology is the study of life. It encompasses the cellular basis of living things, the energy that underlies the activities of life, and the genetic basis for inheritance in organisms. Topics covered include the smallest components of living things: atoms, molecules, organelles, and cells. Part of the "Biology" series.
Viruses are tiny agents that can infect a variety of living organisms, including bacteria, plants, and animals. The Dengue virus is a mosquito-borne viral disease occurring in tropical and subtropical areas. Scientists at the University of California, Berkley have identified a key culprit responsible for the severe symptoms related to Dengue fever.
There's been a lot of talk and research interest around the possibility of resurrecting certain groups of organisms from extinction. In this episode, host Emily Graslie discusses this possibility with a focus on the woolly mammoth and the mastodon. Part of "The Brain Scoop" series.
Host Emily Graslie, Chief Curiosity Corespondent at The Field Museum, introduces this new series. This episode features stories on a newly discovered dinosaur, the different species of trees in the Amazon jungle, a biography of Dr. Margery C. Carlson, and the classification of mammals on Luzon Island in the Philippines. Part of the "Natural News From The Field Museum" series.
Invisible ultra-violet light energy is finding its way into an increasing variety of high-tech applications, such as disinfecting water of hazardous micro-organisms and in the development of paint that dries in seconds. The highly competitive field of computer chip lithography also has chemists and physicists working with ultra-violet light technology. New light technologies are being used to manufacture semiconductors, lenses, and many other technological components.
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.
Are humans the accidental products of an uncaring universe? Or are they the beneficiaries of a cosmic order that was planned beforehand to help them flourish? This documentary explores growing evidence from physics, chemistry, biology, and related fields that our universe was designed for large multi-cellular beings like ourselves. Geneticist and author Michael Denton investigates the special properties of carbon, water, and oxygen that make human life and the life of other organisms possible.
Explores the fascinating features of the animal kingdom. The taxonomy of the different invertebrate and vertebrate phyla are the focus of the program, with special emphasis placed on the evolutionary relationships of the various phyla. Each of the major phyla are discussed, going from simple to more complex organisms. Other terminology includes: sponges, cnidarians, flatworms, roundworms, segmented worms, mollusks, arthropods, echinoderms, fishes, amphibians, reptiles, birds, and mammals.
More than four billion years ago, the most important event in Earth's history took place: the ocean was born. It completely transformed the planet, creating a watery oasis that gave rise to the air that organisms consume, the climate, and a stunning array of life. The ocean is what transformed Earth into the livable, blue planet it is today. This episode tells the story of the ocean's turbulent beginnings and its successive incarnations. Part of the "One Ocean" series.
Part of the "Branches on the Tree of Life" series. Imagine an animal with no mouth, no digestive system, no excretory or circulatory organs, no brain nor nervous system, and no movement as an adult. In spite of their simple nature, sponges are actually one of the most interesting animal phyla when viewed in developmental, ecological, and evolutionary terms. Clarifies the structure, function, classification, and ecological roles of sponges through animations and time-lapse microscopy.
Genetic modification of organisms and cloning is controversial. Looks at the way humanity has modified genomes of plants and animals used for food since the dawn of agriculture. As knowledge of cells and genetics has increased, so has humanity's ability to alter genomes. Shows animations of how genetic engineers are now able to construct and insert genes for desirable characteristics into plants and how technology is used to increase numbers of animals with desirable traits and screen out those with disease or lower food yields.
In 1977, scientists discovered a diverse community of organisms inhabiting the deep-sea hydrothermal vents of the Pacific Ocean. The sources of energy in these ecosystems are hydrogen sulfide and other inorganic chemicals that are abundant in the water that rises from the vents. Scientists discovered that some animals living near hydrothermal vents, such as the giant tube worm, have a symbiotic relationship with species of bacteria, which allows these animals to survive deep in the ocean. Part of the "I Contain Multitudes" series.
Welcome to Barrow, Alaska, where a team of marine ecologists gears up to hit the sea ice that is actually teaming with marine life. With support from the National Science Foundation (NSF), Craig Aumack of Columbia University and a team have come here to investigate how algae in the sea ice contributes to the underlying marine ecosystems, and which marine organisms depend on the algae for nutrition. Part of the National Science Foundation Series “Science Nation.”
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.
Climb aboard the Cyclops, a microscopic research vessel, and investigate an amazing hidden world on which all living things depend. The Cyclops houses a team of scientists known as the Micronauts and guides them through their discoveries of biological classification, diversity, and ecology. While making a documentary, the Micronauts discover the life-rich weedy shallows of the pond. They encounter single celled and multi-celled organisms, and a story unfolds of the diverse ecology found within ponds. Part 3 of the Microscopic Monsters Series.
Presents a brief history of what new information caused the classification of living things to evolve from the original two kingdom classification of animals and plants by Linnaeus in the 18th century to the present-day six kingdoms: Animal, Plant, Fungi, Protista, Eubacteria, and Archaebacteria. Discusses three of the six kingdoms: Protista, Eubacteria, and Archaebacteria. Also, presents the hierarchical classification from kingdom to species. Because viruses do not have the capability of an independent cellular life, they are included in neither the kingdom nor domain classifications.
Part of the "Life in Aquatic Environments" series. Shows the variety of body forms and structures found in an environment ripped by waves. Examines structural, chemical, and behavioral adaptations that protect animals in this crowded environment. Looks at adaptations used to harvest the abundant food sources of the shore. Provides an overview of asexual and sexual strategies and the importance of larval development in the plankton. Reveals complex webs of life living in these accessible habitats.
