A study by Tokyo Metropolitan University using fruit flies has shed light on how daily eating patterns are regulated by genetic components. The quasimodo (qsm)…
A study involving over 60,000 nurses revealed that individuals with an evening chronotype are at an elevated risk for diabetes and often engage in unhealthy…
Traveling to distant locations offers enriching experiences, but jet lag’s unpleasant symptoms can mar the journey. A new study used a theoretical model to explore…
A meta-analysis published in Neurology reveals strong links between cluster headaches, migraines, and the circadian system, which regulates internal body processes. The study emphasizes the…
Research indicates that getting insufficient light during the day leads to problems at night, when it’s time for bed. A study measuring the sleep patterns…
The circadian rhythm, or circadian cycle, is a natural, internal sleep-wake cycle dictated by a roughly 24-hour biological clock. The importance of getting enough shut-eye…
Scientists have uncovered an important molecular link between lung tumor growth and disrupted circadian rhythms. Circadian rhythms, sometimes called the “biological clock,” is the cellular…
Syncing your circadian rhythm to a natural light-dark cycle could improve your health and well-being. Have you ever suffered from jet lag or struggled after…
According to new research published in Science Advances, both genetic and environmental disruption of the circadian clock can drive colorectal cancer progression. Research illustrates how…

Eating only during your most active time of day, while following a reduced-calorie diet, may lead to a substantially longer life, according to new research…
Research team reveals what drives the circadian rhythms in cyanobacteria. Scientists want to increase their understanding of circadian rhythms, those internal 24-hour biological clock cycles…

Image Caption: The image of a clock with brightfield macrophage images around it shows how circadian changes of cell surface heparan sulfate proteoglycans, shown in…
Disrupting circadian rhythms, which change naturally on a 24-hour cycle, has been implicated in heart disease, but it is unclear how it leads to the…
A small clinical trial supported by the National Institutes of Health has found that eating during the nighttime—like many shift workers do—can increase glucose levels,…
The migration of dendritic cells from the skin into lymphatic vessels depends on the time of day. Mouse dendritic cells (green) migrating into the lymphatic…
