Research finds that a high-sugar diet supplied by tourists is giving Bahamian rock iguanas the lizard equivalent of high blood sugar.

Obese mice that exercised while pregnant gave birth to pups that grew up free of the metabolic issues present in the adult young of sedentary obese mothers—possibly by staving off epigenetic changes to a key metabolic gene.

A study of 19 postmenopausal women found that eating a bar of chocolate in the morning affected their bodies differently than eating it at night, but neither led to weight gain.

Healthy people put through high-intensity interval training, or HIIT, displayed insulin resistance and mitochondrial dysfunction after working out excessively.

Timekeepers in muscle help mediate metabolism, and may influence neurological processes such as sleep.

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.

Patients with neonatal progeroid syndrome lack a glucose-releasing hormone, while people with insulin resistance have an abundance.

Overeating and inactivity lead to insulin resistance in just days—and oxidative stress is to blame.

Glucose activates sleep-promoting neurons in the mouse hypothalamus.

The body’s circadian rhythm has more of an effect on glucose tolerance than one’s eating and sleeping patterns, a study shows.  

Research reveals how the brain changes as we age and hints at ways to slow the decline.

See human brains age in week-by-week time lapse images that divulge the existence of tiny strokes that damage white matter.

An inspiring lecturer turned Marcus Raichle’s focus from music and history to science. Since then, he has pioneered the use of imaging to study how our brains function.

The consumption of artificial sweeteners results in glucose intolerance mediated by changes in the gut microbiota in both mice and humans, researchers report.

Drosophila insulin-like peptides (dILPs) regulate part of the signaling pathway that helps keep organs growing in proportion during development.

During development, communication between organs determines their relative final size.

Certain immune cells keep adipose tissue in check by helping to define normal and abnormal physiological states.
