A reconstituted circadian clock of cyanobacteria can run for consistent days, allowing researchers to study the interactions of the clock proteins in real-time and observe how the clock exerts control over gene expression.
Night-shifts destroy the natural 24-hour biological rhythm in the activity of certain cancer-related genes, resulting in more vulnerability to DNA damage and causing a mistiming in the DNA repair mechanisms in shift workers.
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.
Stress makes the circadian clock tick faster and better.
Yesterday, the Nobel Assembly at the Karolinska Institute announced the 2017 Nobel Prize for Physiology or Medicine is to be awarded jointly to Jeffrey C. Hall, Michael Rosbash and Michael W. Young for their work unraveling the molecular mechanisms behind circadian rhythm.
A new study report different groups of neurons program our circadian clocks to orchestrate behavior by sending messages in a unidirectional manner downstream.
A new study sheds light on how the retina sets its own biological rhythm using a novel light-sensitive pigment called neuropsin.
A new study reports drinking caffeine during the evening delays the internal body clock by 40 minutes.
Researchers discover changes in the activity of sodium and potassium channels during the day and night impact the sleep-wake cycle.
