With driver’s licenses in hand, teens may think they’re road-ready, safe drivers. But tapping the brakes to consider how the adolescent brain develops might be a good idea. Young drivers whose brain function lags behind that of their peers are more likely to report having a car crash. That’s the finding of a new study.…

Fatal Brain Cancers Imitate ‘Vampires’ By Pirating Regular Cells To Grow

Fatal Brain Cancers Imitate ‘Vampires’ By Pirating Regular Cells To Grow

Researchers are beginning to understand why certain brain cancers are so hard to stop. Three studies published Wednesday in the journal Nature found that these deadly tumors integrate themselves into the brain's electrical network and then hijack signals from healthy nerve cells to fuel their own growth. "They are like vampires" feeding on brain activity,…

Human-like mind waves detected in mini brains grown in a dish

A cross-section of the lab grown mini-brains, with each color representing a different type of brain cell. Muotri Lab/UCTV Scientists have successfully grown mini brains that, for the first time, produce brain waves resembling those seen in embryos and preterm infants. Researchers at the University of California, San Diego (UCSD) created the pea-sized "brains" by…

What drug does to your body and brain

Whether it's snorted, smoked, or injected, cocaine enters the bloodstream and starts affecting the brain in a matter of seconds. But the high is short-lived, and in most cases lasts anywhere from five to 30 minutes. Regular, heavy use can have extremely negative consequences, from nosebleeds to permanent lung damage and even death. Here's a…

(more about Power Words) brain scan     A technique to view structures inside the brain, typically with X-rays or a magnetic resonance imaging (or MRI) machine. With MRI technology — especially the type known as functional MRI (or fMRI) — the activity of different brain regions can be viewed during an event, such as viewing pictures, computing…
