  • Koalas

    • Video
    Close up of a young koala bear holding on to a larger furry body. Caption: Eventually, the youngster starts to explore.

    The Australian Koala Foundation works diligently to educate authorities about the probable destruction of this familiar animal. Closeup photography reveals its habitat, social structure, characteristics, mating habits, and interaction. Compromises between the needs of people and the eucalyptus habitat needs of the koalas mean hope for its future.

  • Stem and roots of a plant pressed against the wall of a glass jar. Caption: Roots and stems are sensitive to gravity.

    Some plants have leaves and some have needles, but they all need a way to absorb sunlight, nutrients, air, and water. Shares a basic overview of plant structure and the essential role plants have on earth. Defines deciduous, coniferous, photosynthesis, and capillary action. Suggests several classroom experiments.

  • 3D computer image of a partially destroyed skeletal structure. Caption: digital representations of skeletal anatomy

    Host Emily Graslie meets with Dr. Ryan Felice to discuss the 3-D surface scanner, which he uses to create digital representations of skeletal anatomy. He visits various museums and scans their collections hoping to help preserve research findings. Part of "The Brain Scoop" series.

  • Alex Dainis is seated in front of her book shelf. Animation of a cell structure. Caption: And this volume includes all of its organelles.

    Host Alex Dainis discusses mitrochondrial DNA, which is the smallest circular chromosome found inside mitochondria. These organelles found in cells have often been called the powerhouse of the cell. The mitochondria, and thus mitochondrial DNA, are passed almost exclusively from mother to offspring through the egg cell.

  • Narrow paved path spiraling to the top of a rocky conical structure. Caption: a great fissure opened up in Central Idaho

    Craters of the Moon is a vast ocean of lava flows with scattered islands of cinder cones and sagebrush. Idaho’s Craters of the Moon formed during eight major eruptive periods between 15,000 and 2,000 years ago. The monument continues to go through subtle changes caused by natural and human processes.

  • Pile of dark substance with eyes on the ground next to a bus stop. Caption: what's left of you, you're about 2/3 carbon.

    The scientific explanation of global warming rests in the understand of the element carbon. Carbon is the central element of life, and its atomic structure enables it to hold onto other elements. This characteristic provides the relationship between carbon and global warming. Segment of video from Wild Chronicles Series.

  • Person holding a taxidermized flying squirrel with legs extended. Caption: As you know, flying squirrels don't fly, they glide.

    In this behind-the-scenes glimpse into the skeletal collections at The Field Museum, host Emily Graslie examines various elephant skeletons. Bill Stanley, Director of the Gantz Family Collections Center, describes the differences in skull structure between the species. Part of "The Brain Scoop" series.

  • Cross section of a cell showing a ribbon-like structure. Caption: with the inner membrane folded, increasing its surface area

    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.

  • A lighthouse with the sails of ships in the background. Caption: the same natural enemy-- erosion.

    The residents of Block Island fight to save a sea side lighthouse from beach erosion. They join together and hire a team of brothers to move the lighthouse back from the cliffs. The 2,000 ton structure is moved 300 feet in an effort to save it from the ongoing erosion of the bluffs along the coast of Rhode Island.

  • A cartoon shows the skeletal structure of a giant dinosaur.

    From end to end, its forelimbs alone measured an incredible 2.4 meters long and were tipped with big, comma-shaped claws. But other than its bizarre arms, very little material from this dinosaur had been found: no skull, no feet. Scientists were unable to create a full picture of this dinosaur until they began exploring quarries in 2006 and 2009. Part of the "Eons" series.

  • Daphnia

    • Video
    Extreme closeup of the cell structure showing the translucent outline of the heart. Caption: Daphnia's heart keeps its circulatory fluid in motion.

    Part of the "The Biology Classics" series. Daphnia are small, planktonic crustaceans. Provides a classic study in arthropod behavior and anatomy. Examines the eye, brain, jaws, intestine, legs (with gills), and heart. Identifies two kinds of eggs: those that hatch directly into female daphnia and resistant eggs that carry the species through periods of freezing and drying.

    Hydroxyl groups, which consist of upper case O upper case H attached to a carbon chain, are polar. Methyl groups, which consist of three hydrogens attached to a carbon chain, are nonpolar.

    Figure 2.27 (OpenStax, Biology 2e) caption: These functional groups are in many different biological molecules. R, also known as R-group, is an abbreviation for any group in which a carbon or hydrogen atom is attached to the rest of the molecule.
