Prof. Sophie Scott has more laughter science for you, this time at the normally quite serious Royal Society. As part of the Royal Society Summer Science Exhibition running from 3-8 July 2012.

Scientists have found that the brains of people who are good at distinguishing different kinds of laughs show a greater tendency to join in with the laughter they hear
