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. Read More
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
Stress makes the circadian clock tick faster and better. Read More
Researchers report metabolic disruptions often seen in shift workers are not influenced by the brain's circadian rhythm, but by peripheral oscillators in the liver, gut and pancreas. Read More
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. Read More
A new study report different groups of neurons program our circadian clocks to orchestrate behavior by sending messages in a unidirectional manner downstream. Read More
A new study sheds light on how the retina sets its own biological rhythm using a novel light-sensitive pigment called neuropsin. Read More
A new study reports drinking caffeine during the evening delays the internal body clock by 40 minutes. Read More
Researchers discover changes in the activity of sodium and potassium channels during the day and night impact the sleep-wake cycle. Read More
Researchers report correct coordination between our circadian clock and gut bacteria could be critical for preventing metabolic diseases. Read More
A new study shows sufferers of seasonally affective disorder (SAD), like insomniacs, report sleep patterns incorrectly due to depression. Read More
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
