Molecular switch mechanism explains how mutations shorten biological clocks

Study reveals how certain genetic mutations can shorten the timing of the circadian clock, making some people extreme "morning larks" because their internal clock operates on a 20-hour cycle, as opposed to a 24-hour cycle. Read More

Key Protein is Linked to Circadian Clocks, Helps Regulate Metabolism

A new study reveals how the production of p75NTR protein oscillates in time with the body's natural circadian rhythm and how these oscillations help regulate vital metabolic functions. The findings offer an insight into how circadian rhythm helps maintain the body's overall metabolic health. Read More

Scientists Map the Wiring of the Biological Clock

Researchers report the discovery of a crucial part of the biological clock: the wiring that sets its accuracy to within a few minutes out of the 1440 minutes per day. The wiring uses GABA to connect the individual cells of the biological clock in a fast network which changes strength with the time of day. Read More
