  • Viral Outbreak: The Science of Emerging Disease

    Viral Outbreak: The Science of Emerging Disease


    Watch two leading virus researchers explain how they use both simple and sophisticated technologies to detect and fight infectious agents.

  • Dengue Virus Life Cycle

    Dengue Virus Life Cycle


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

  • Origin of HIV

    Origin of HIV


    (5 min 32 sec) Dr. Beatrice Hahn's research has traced the origin of HIV to chimpanzees in Cameroon.

  • HIV life cycle

    HIV life cycle


    (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


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

  • Emerging Infections: How Epidemics Arise

    Emerging Infections: How Epidemics Arise


    (59 min) Dr. Ganem analyses the complex causes of epidemics—how changes in the environment and in human social behavior can give rise to new infectious diseases.

  • Recombination of Viral Genome

    Recombination of Viral Genome


    (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.
