Scientists from Florida International University have learned to determine the sex of a person by the smell of hands. The results of the work were published in the journal PLOS ONE.
To do this, experts used mass spectrometric analysis, which revealed specific volatile compounds in the palms of 60 people (half a man and half a woman). The team then ran a statistical analysis to see if the data could determine the gender of the person. The developed method with an accuracy of 96.67 percent allows you to successfully predict who owns the smell. Related materials: Chipping people, editing DNA and an alternative to antibiotics.
