The cell cycle is the series of events that cells go through as they grow and divide. This title provides a discussion on each of the stages of the cell cycle: prophase, metaphase, anaphase, telophase, and cytokinesis. Part of the "Biology" series.
Part of the "Inside the Living Cell" series. Shows how DNA replicates; how copy errors occur and are subsequently corrected by repair enzymes; and how DNA is compressed into chromosomes, making mitosis and cell division possible. Provides an overview of DNA structure, replicating DNA, mutations that change the genetic code, proofreading and repair, and the stages of mitosis.
Provides an overview of some natural and human-made wonders of the world. Natural forces created mountains and canyons, unique bodies of water, and diverse ecosystems. People made ancient cliff dwellings, Stonehenge, pyramids, the Great Wall, and Hoover Dam, some very significant structures. All reveal the history of earth and its inhabitants.
Part of the "Branches on the Tree of Life" series. Explores the structure, life cycles, ecology, classification, and evolutionary relationships of four major lines of fungi: Chytrids, Zygomycetes (various molds), Ascomycetes (yeasts, cup fungi, and most lichens), and Basidiomycetes (rusts and mushrooms). Emphasizes adaptations and reproductive mechanisms.
Part of the "Inside the Living Cell" series. Describes the properties of the plasma membrane, how it governs the kinds of molecules that go in and out of cells, and how cells feed by engulfing (phagocytosis) and drinking in (pinocytosis) fluids. Also reviews membrane structure, osmosis, transport proteins, active transport, cell eating, cell drinking, and receptor proteins.
Diagram of a cross-section of the internal view of a human eye. Design modalities for the image include braille with and without labels, print with and without labels in greyscale, color, and texture.

Explains the science behind the workings of a nuclear power station. The basic version explores what fission is; the role of cooling water in nuclear reactors; the nuclear fuel cycle on mining, milling, enrichment, fabrication, and spent fuel on storage and reprocessing; and other uses of nuclear energy, including "non-power" uses. The advanced version expands on this information with a specific example of a fission reaction; the use of water to vary reactor power; different methods of mining uranium; a detailed discussion of enrichment, including structure and properties of uranium hexafluoride; and two methods of enrichment: centrifuging and gas diffusion.
Researchers at the state-of-the-art Structural Engineering and Materials Laboratory at the Georgia Institute of Technology are using a full-scale model building to test new ways to protect structures from earthquakes and potentially save lives. The three-story concrete building is based on designs common through much of the 20th century. It has been subjected to round after round of simulated temblors to test if materials such as carbon fiber or new shape-memory alloys can be used to reinforce the structure so it would remain standing in moderate to strong earthquakes. With support from the National Science Foundation, structural engineer Reginald DesRoches and his team have developed a series of retrofits of varying cost and intrusiveness to give building owners in quake-prone areas a range of choices for hardening their property.
Part of the "Gunther's ER" series. The human brain suffers irreversible damage if deprived of oxygen for even a few minutes-a fact Dr. Gunther von Hagens demonstrates by utilizing human cadavers as examples. Simulating an artery injury to illustrate oxygen depletion through blood loss, von Hagens then focuses on problems affecting the trachea, the top priority for ER doctors. In order to show the major structures of the airway and how they can be blocked by foreign objects, von Hagens inserts an endoscope into his own throat and saws a frozen body's throat in half, revealing the major structures of the airway and their potential weaknesses. Red Cross first-aid expert Emma Rand explains simple techniques for clearing the airway, while emergency medicine consultant Dr. John Heyworth shows how paramedics treat complex trachea damage. NOTE: Viewer discretion is advised. Contains clinically explicit language and nudity.
Discusses the terminology, processes, and products related to photosynthesis. Questions bridge segments and lead to information on tropism, seed structure, and germination. Includes a review and a quiz.
Students investigate important processes including photosynthesis, reproduction, growth, and germination. They also learn how these processes relate to the structure of plants. Important terminology includes flower, pistil, stamen, pollen, pollination, and reproduction.
This episode discusses the importance of scientific names and why classification can have major changes due to DNA and cell structure evidence. Pinky and Petunia also cover the taxonomy hierarchy of classification. Part of "The Amoeba Sisters" series.
Deeply explores the structure of both plant and animal cells. Demonstrates the different types of cells, their components, and their functions
Athletes demonstrate their flexibility in this look at our ingeniously designed muscular-skeletal system. Discusses muscle and bone interaction, their structure, purpose, and function. Comments on technological studies on motion.
Live-action footage conveys basic features of the major invertebrate groups. Special attention is paid to the body structure and physical features of simple animals. Other terminology includes backbone, sponge, sea anemone, radial symmetry, planaria, earthworm, bilateral symmetry, exoskeleton, segmented body, and jointed appendages.
Students will learn about the structure and characteristics of seeds and plants. They will also learn about the diversity of plants throughout the various land regions of the world. Part of the Real World Science series.
Part of the "Visualizing Cell Processes" series. Includes the following modules: "Mitosis: Chromosome Condensation," "Mitosis: Stages," "Cytokinesis," "Meiosis," "Nucleotide Structure and Bonding," "Replication Enzymes," "Replicating the Strands," "The Twisting Problem," and "Proofreading and Repair."
Tour three Martian landscapes and find out how erosion and water has affected the surface of Mars. Flyover images show the structure and composition of the landscape of Mars and focus on Candor Chasma, part of a canyon system of Mars.
What is neuroplasticity? CEO and founder of TAO Connect, Sherry Benton, explains the brain's ability to reorganize itself by forming new neural connections throughout life. Part of the "Ask a Scientists" series.
