  • Fruit Fly Courtship

    Fruit Fly Courtship

    Clip

    (55 sec) Male courtship dances in two fruit fly species show that the wing spots play a prominent role.

  • The Science of Fat

    The Science of Fat

    Lecture

    In the 2004 Holiday Lectures on Science, HHMI investigators Ronald M. Evans and Jeffrey M. Friedman discuss how the body regulates weight by carefully controlling the storage and burning of fat—and how a better understanding of these complex metabolic systems could lead researchers to treatments that curb obesity and improve public health.

  • Leptin Feedback Control System

    Leptin Feedback Control System

    Animation

    (1 min 1 sec) Demonstrates how changes in the amount of fat tissue lead to changes in leptin levels and thus changes in appetite.

  • Are You a Morning or an Evening Person?

    Are You a Morning or an Evening Person?

    Click & Learn

    This survey, developed by Horne and Ostberg, will let you determine if you are a morning or an evening person.

  • Transgenic Fly Virtual Lab

    Transgenic Fly Virtual Lab

    Virtual Lab

    The lab will familiarize you with the science and techniques used to make transgenic flies to study circadian rhythms.

  • Clockwork Genes: Discoveries in Biological Time

    Clockwork Genes: Discoveries in Biological Time

    Lecture

    Four lectures highlight the research of two scientists who have made groundbreaking discoveries elucidating the molecular basis of circadian clocks—the internal timekeepers that govern fluctuations in behavior and physiology on a 24-hour cycle.

  • The Drosophila Molecular Clock Model

    The Drosophila Molecular Clock Model

    Animation

    (7 min 35 sec) Watch these animations display the dynamic orchestration of the molecular events of the Drosophila biological clock.

  • Measuring Circadian Activity in Drosophila

    Measuring Circadian Activity in Drosophila

    Animation

    (2 min 3 sec) This animation series shows four experiments that compare the activity patterns of a wild-type fly keeping a normal schedule with those of a mutant fly apparently following a 19-hour internal clock.

  • The Mammalian Molecular Clock Model

    The Mammalian Molecular Clock Model

    Animation

    (3 min 41 sec) This animation shows the molecular interactions involved in the negative feedback loop responsible for circadian rhythms in mammals.
