To better understand the circadian clock in modern cyanobacteria, a Japanese research team has investigated ancient time-keeping systems. They studied the oscillation of the clock proteins KaiA, KaiB, and KaiC (Kai proteins) in modern cyanobacteria and compared it with the function of the Kai proteins of their ancestors. Their research findings were published in Nature […]
The combination of mathematical modeling and experiments identifies the difference in the molecular clockwork of master and slave clock neurons in Drosophila. This solves the long-standing mystery of the molecular mechanisms responsible for the circadian (~24-hour) clock’s paradoxical properties of robustness (strong rhythms) and plasticity (flexible adaptation). How Our Daily Rhythm is Regulated From tiny […]
Some people jump out of bed in the early hours of the morning, while others prefer a slower start to the day. Whether you get up with a smile or a groan, scientists say that your internal clock—known as your circadian rhythm—could influence this behavior and much more. Timing of Activities can Play a Role […]
Caffeine is not only found in coffee, but also in tea, chocolate, energy drinks, and many soft drinks, making it one of the most widely consumed psychoactive substances in the world. In a study published in Nature Communications Biology, a team of researchers from the Université de Montréal has gained new insights into how caffeine […]
Sleep experts advise against using the snooze button after the alarm clock rings. However, a study led by researchers at Mass General Brigham shows that this practice is widespread: more than 50% of recorded sleep phases end with a snooze alarm, and people spend an average of 11 minutes snoozing. Using data from the sleep […]
