Study reveals key molecular interaction that sets the timing of our biological clocks
New findings point toward a promising target for the development of therapies for sleep disorders, jet lag, and other effects of clock disruption
Scientists assemble a biological clock in a test tube to study how it works
A team of scientists has reconstituted the circadian clock of cyanobacteria in a test tube, enabling them to study rhythmic interactions of the clock proteins in real time and understand how these interactions enable the clock to exert control over gene expression.
Early riser or night owl? New study may help to explain the difference
An NIH-funded team has some new clues based on evidence showing how a molecular “switch” wired into the biological clocks of extreme early risers leads them to operate on a daily cycle of about 20 hours instead of a full 24-hour, or circadian cycle.
