Researchers are making groundbreaking discoveries in understanding the molecular basis of circadian clocks?the internal timekeepers that govern fluctuations in behavior and physiology on a 24-hour cycle. In four lectures, Dr. Michael Rosbash and Dr. Joseph S. Takahashi explain what circadian clocks are, how they work, and what relevance this knowledge might have for human health. They describe the techniques that led to their discoveries of the genes, proteins, and other components that make up these complex biological pacemakers. The scientists use animations to illustrate complex concepts and answer questions from their student audience.
