    Think Like a Scientist: Natural Selection in an Outbreak

    Scientists at Work

    (7 min 29 sec) This video brings us to the front lines of the 2013–2015 Ebola outbreak in west Africa and explains how scientists monitored the evolution of the virus by analyzing its genome.

  • Genetically Modified Mosquitoes

    Genetically Modified Mosquitoes

    Scientists at Work

    (8 min 35 sec) Learn the process by which a line of genetically modified mosquitoes was engineered to reduce populations of Aedes aegypti mosquitoes in the wild.

  • Virus Hunter: Monitoring Nipah Virus in Bat Populations

    Virus Hunter: Monitoring Nipah Virus in Bat Populations

    Scientists at Work

    (9 min 1 sec) In this video we follow scientists working in Bangladesh as they test fruit bat populations to determine whether they are infected with Nipah virus—a potentially deadly virus when passed on to humans.

  • The Mosquito Life Cycle

    The Mosquito Life Cycle

    Clips

    (1 min 7 sec) To prevent mosquitoes from spreading diseases, it's essential to understand their life cycle.

  • Bee Colony Collapse Disorder

    Bee Colony Collapse Disorder

    Clips

    (7 min 46 sec) Charles Runckel, a graduate student in the DeRisi lab, uses the Virochip to examine the mystery of bee colony collapse disorder.

  • Dengue Virus Enters a Cell

    Dengue Virus Enters a Cell

    Animations

    (1 min 33 sec) Infection begins when the dengue virus uses receptors on an immune cell's surface to gain entry and release its genome.

  • Structure of Dengue Virus

    Structure of Dengue Virus

    Animations

    (1 min 3 sec) The dengue virus's outer envelope proteins form symmetrical units and overlay the lipid envelope, capsid, and the RNA genome.

  • Dengue Virus Life Cycle

    Dengue Virus Life Cycle

    Animations

    (4 min 12 sec) Dengue virus has sophisticated mechanisms for entering a cell, for replicating its RNA genome, and for translating proteins.

  • Viral Geometry and Structural Diversity

    Viral Geometry and Structural Diversity

    Animations

    The geometric structures of viruses are beautiful and can be used, along with genomic information, to identify them.

  • HIV life cycle

    HIV life cycle

    Animations

    (4 min 52 sec) How HIV infects a cell and replicates itself using reverse transcriptase and the host's cellular machinery.

  • AZT blocks reverse transcriptase

    AZT blocks reverse transcriptase

    Animations

    (1 min 46 sec) HIV's reverse transcriptase mistakes AZT for thymidine. Once incorporated, AZT stops reverse transcription.

  • Using p53 to Fight Cancer

    Using p53 to Fight Cancer

    Animations

    (1 min 2 sec) This animation demonstrates how cancerous cells could be destroyed using a modified virus.

  • Size Analogies of Bacteria and Viruses

    Size Analogies of Bacteria and Viruses

    Clips

    (1 min 44 sec) Dr. Finlay and Dr. Richard Ganem use physical analogies to compare the size of bacteria and viruses relative to a standard mammalian cell.

  • Recombination of Viral Genome

    Recombination of Viral Genome

    Animations

    (3 min 5 sec) When two different strains of influenza infect a single cell, their genetic material can mix freely, resulting in a new third strain of influenza.

  • Viral Lifecycle

    Viral Lifecycle

    Animations

    (1 min 8 sec) Delivering a single virus to a cell allows the virus to infect the cell, replicate, and give rise to many progeny viruses. These viruses can then infect many neighboring cells. Also available in Spanish.
