What exactly happens to your face when you smile spontaneously, and how does that affect how old you look? Computer scientists from the University of Amsterdam’s (UvA) Faculty of Science recorded the smiles of hundreds of visitors to the NEMO science centre in Amsterdam, thus creating the most comprehensive smile database ever. The results can be seen via the link below. The research was conducted as part of the project Science Live, sponsored by the Netherlands Organisation for Scientific Research (NOW) and the Royal Netherlands Academy of Arts and Sciences (KNAW).
