Disrupted circadian rhythms linked to later Parkinson’s diagnoses

Circadian rhythm disruptions in older men have been linked to an increased risk of developing Parkinson's disease. The findings suggest circadian disruptions may reflect the neurodegenerative processes already affecting the brain's internal clock prior to the diagnosis of Parkinson's. Circadian disruptions, researchers say, could be considered an early warning sign of Parkinson's. Read More

Eyes send an unexpected signal to the brain

A new study puts into question conventional belief that the eyes communicate with the brain exclusively via one signaling pathway. Researchers have identified a subset of retinal neurons that sends inhibitory signals to the brain. This subset of neurons is also involved in the synchronization of circadian rhythms to light/dark cycles and pupil constriction to bright light intensity. Read More

When should you eat to manage your weight? Breakfast, not late-night snacks

Losing weight isn't just a case of restricting the foods or calories you eat, it also comes down to when you eat. Skipping breakfast and snacking late at night delays the body's fat-burning mechanisms. Read More

Bmal1 gene is not an essential regulator of circadian rhythms

Deleting the circadian rhythm-associated BMAL1 gene in animal models, researchers discovered tissue continued to follow a 24-hour rhythm, even in the absence of external stimuli that can influence the cycle. Read More

Molecular switch mechanism explains how mutations shorten biological clocks

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
