A new study is the first to identify that a conserved gene – translin – works as a modulator of sleep in response to metabolic changes. The sleep habits of fruit flies are remarkably similar to humans. They get most of their sleep at night, certain drugs and stimulants like caffeine can negatively affect their sleep, and if they get a lousy night’s sleep it can even affect their memory performance.

When fruit flies are hungry, they sleep less because they will sacrifice sleep for their...

New research finds that one night of sleep deprivation and six months on a high-fat diet could both impair insulin sensitivity to a similar degree, demonstrating the importance of a good night’s sleep on health. (stock image) Credit: © tab62 / Fotolia

New research finds 1 night of sleep deprivation and six months on a high-fat diet could both impair insulin sensitivity to a similar degree, demonstrating the importance of a good night’s sleep on health. This study used a canine model to examine whether sleep deprivation and a high-fat diet affect insulin sensitivity in similar ways.

When the body becomes insulin resistant, it needs to produce more insulin to keep blood sugar stable. This may eventually lead to Type 2 diabetes which is a/w heart disease...
