Feb 24, 2014 — Sriracha and other spicy condiments make us feel so good, even when they burn so bad. So what's going on in our tongues? A video breaks down the beloved hot sauce into its molecular components.
Feb 21, 2014 — Anyone who's had MRI knows how hard it is to lie motionless. But the dogs that participated in this brain-scanning experiment aced the test. Maybe the treats did it.
Feb 10, 2014 — Skipping a meal triggers the munchies in a similar way that marijuana does, a study in mice finds. And it works, at least in rodents, by boosting the sense of smell. Receptors in the brain that get activated when the animals are stoned also light up after they've been fasting.
Feb 5, 2014 — People who are blind from birth are often better than sighted people at processing certain aspects of sound. A mouse study hints at why: Even a few days in the dark helped "rewire" the auditory center of an adult animal's brain.
Feb 5, 2014 — Many scientists have been trying to create neural implants that will let amputees regain a sense of touch and control. One version has let a Danish man feel the texture of things he's touching. But it's an experimental model that's not yet ready for use outside the laboratory.
Feb 5, 2014 — Even people with good memories can have a hard time remembering the past accurately. That may be because the brain is constantly editing memories, updating them with current information. This may make good evolutionary sense. But it also means that some of your cherished memories may be wrong.
Jan 24, 2014 — Expectant moms are eating for two, but that isn't a license to indulge. A solid body of research suggests that what happens in utero can set the stage for obesity. And a new study in mice suggests one way that poor maternal diet might play a role: by rewiring a part of the brain that regulates appetite.
Dec 30, 2013 — How do you know you're in love? Angry? Or sad? Emotions start off in the brain, then ripple through the whole body. Now scientists have charted where we consciously feel specific emotions. They hope these sensation maps will one day help diagnose and treat mood disorders.
Dec 27, 2013 — Scientists hope to solve mysteries of the human brain by studying much simpler neural networks — like the brain circuits of fruit flies and mice. Already such research is turning up clues to why many people with autism are easily overwhelmed by bright lights and loud sound.
Dec 10, 2013 — All medications come with risks, and one of the risks with popular heartburn medicines seems to be that they interfere with the absorption of vitamin B-12. That can cause troubling symptoms, from anemia and depression to dementia.
