Scientists build a biosensor skin patch for noninvasive glucose monitoring. 

A needle-free alternative to the finger-prick test would be a godsend for many sufferers of diabetes, but the industry has yet to clear the technological hurdles.

Overall brain metabolic rate can distinguish between pathological states of human consciousness, a study shows.

Glucose activates sleep-promoting neurons in the mouse hypothalamus.
