Scientists are Studying Hair Proteins as a New Method of Forensic Profiling

A research laboratory in California, Lawrence Livermore National Laboratory has discovered that their study of 82 living and recovered hair samples yielded evidence of hair proteomics, proteins that genes produce. The scientists hypothesize that hair proteins can be used to identify genetic mutations. Eventually, they believe, protein analysis will join DNA analysis as a key technique in exonerating and determining suspects. Such protein mutations occur because DNA mutations also lightly impact amino acids, which construct proteins. One proponent of new forensic profiling techniques is Glinda S. Cooper, director of the Innocence Project, a non-profit organization dedicated to helping wrongly convicted victims. Overall, the new discovery is a possible "game-changer" according to Christopher J. Hopkins, a forensic science director at University of California at Davis.
