For more than a century, forensic scientists have scoured crime scenes for fingerprints to help identify who was present during a crime. New research goes beyond the swirls and whorls of fingerprint patterns to demonstrate that the amino acids in the sweat within fingerprints can identify the sex of the person who made them (Anal.
