When you scarf down a massive dinner, your stomach will stretch to fit each morsel, activating receptors that ping the brain to let it know when you are "full."
A group of engineers has developed a vibrating pill that could help trigger that filled-up sensation sooner, which may one day help treat obesity. When the ingestible pill was given to pigs 20 minutes before eating, they ate roughly 40% less than pigs without the vibrating device, according to a study published Dec. 22 in the journal Science Advances.
