NIST unveils forensic technique to measure mechanical properties of evidence

(National Institute of Standards and Technology (NIST)) Judging forensic evidence such as hair by looks alone can be deceiving, as well as vague and subjective. Instead, what if investigators could precisely measure a hair's mechanical properties -- its stiffness and stickiness? In fact, they can, according to recent experiments at the National Institute of Standards and Technology, which is developing science-based methods to help ensure rigorous forensic practices.
