Symptoms of Prader-Willi Syndrome Associated with Interference in Circadian, Metabolic Genes

Prader-Willi syndrome, a genetic disorder characterized by an insatiable appetite, is associated with the loss of non-coding RNAs; resulting in dysregulation of the circadian and metabolic genes.

Key Protein is Linked to Circadian Clocks, Helps Regulate Metabolism

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.

Scientists Map the Wiring of the Biological Clock

Researchers report the discovery of a crucial part of the biological clock: the wiring that sets its accuracy to within a few minutes out of the 1440 minutes per day. The wiring uses GABA to connect the individual cells of the biological clock in a fast network which changes strength with the time of day.

Eat to Dream: Study Shows Dietary Nutrients Associated with Certain Sleep Patterns

A study shows for the first time that certain nutrients may play an underlying role in short and long sleep duration and that people who report eating a large variety of foods; an indicator of an overall healthy diet, had the healthiest sleep patterns.
