The emotional component, known as mirth, is usually associated with the motor component, namely, bilateral facial movements.”-Yamao et al. (2014)The subject of laughter has been under an increasing amount of scientific scrutiny.  A recent review by Dr. Sophie Scott and colleagues (Scott et al., 2014) emphasized that laughter is a social emotion.

mTOR and the fountain of youth

by Gabriel in Lunatic Laboratories

The fountain of youth might be just right around the corner, I know here at the labs we’ve reported several different ways to get to that fabled place, but now we have one more. New research shows that seniors received a significant boost to their immune systems when given a drug that targets a genetic signaling pathway linked to aging and immune function.... Read more »
