    Termites Digest Wood Thanks To Microbes

    Feature Films

    (7 min 11 sec) The next time you spot a termite chomping down on wood, know that they’re not dining alone.

  • Genes as Medicine

    Genes as Medicine

    Short Films

    (17 min 16 sec) Watch the story of how gene therapy restored the sight of a nearly-blind young patient. Told from the perspective of two researchers who spent over 25 years working to develop this breakthrough technology, this short film chronicles their successes and challenges, and illustrates how the method works to treat inherited conditions.

  • Identifying the Key Genes for Regeneration

    Identifying the Key Genes for Regeneration

    Scientists at Work

    (9 min 55 sec) Planarians have an amazing ability to regenerate lost tissues. In this video, scientists knock out two different genes in planaria to start to understand how the process works—and they generate animals with two heads and two tails!

  • How Lizards Find Their Way Home

    How Lizards Find Their Way Home

    Scientists at Work

    (8 min 33 sec) When Dr. Manuel Leal removed lizards from an area in the forest, he noticed an interesting phenomenon: all the lizards seemed to be back the next day. Watch as he sets up an experiment to study how these lizards navigate home. Also available in Spanish.

  • Seed Dispersal and Habitat Fragmentation

    Seed Dispersal and Habitat Fragmentation

    Scientists at Work

    (8 min 3 sec) Watch researchers follow brown spider monkeys in a tropical forest of Colombia to determine which plant seeds they are dispersing. Seed dispersers are critical to the forest’s ability to grow and regenerate. 

  • Trophic Cascades in Salt Marsh Ecosystems

    Trophic Cascades in Salt Marsh Ecosystems

    Scientists at Work

    (10 min 1 sec) Ecologist Brian Silliman uses manipulative field experiments to reveal that salt marsh ecosystems are under top down control from consumers and predators.

    Riverine Food Webs – How Flow Rates Affect Biomass

    Scientists at Work

    (9 min 15 sec) Ecologist Mary Power studies the Eel River in Northern California to figure out the connection between river flows and biodiversity.

  • Studying Elephant Communication

    Studying Elephant Communication

    Scientists at Work

    (6 min 43 sec) Elephants can communicate over long distances using low-frequency sounds that travel both in the air and through the ground. Scientists are studying whether elephants can “hear” and interpret these ground vibrations.
