Babies who experience low blood sugar at or near birth are at least two to three times more likely to face problems with planning, memory, attention, problem-solving and visual-motor coordination by the age of 4.5, New Zealand researchers said. The low blood sugar (glucose) did not...

She works at the Manhattan Eye, Ear and Throat Hospital in New York City. Floaters become more common with...

    Posted: 07/17/2017

    Laughter May Be a Serious Evolutionary Tool THURSDAY, July 6, 2017 (HealthDay News) -- Sharing a laugh can make you feel closer to someone else, and that quick-forming social bond may have been a big evolutionary boon to human survival, a small study suggests. The act of laughing out loud triggers the brain to release its very own "feel good" neurotransmitters, known as endorphins, the study's brain scans showed. Endorphins are naturally occurring opioids that may produce a sense of euphoria, calmness a...
