Criminals might soon be identified by a single strand of hair – even 250 years later

[Larry Davis]

DNA evidence has shined a light on many a mystery, from helping trace the roots of the Great Plague to adding critical plot twists to every other episode of CSI: Crime Scene Investigation. But DNA samples are easily degraded and when subjected to things like light and heat they can become pretty useless pretty quickly. Scientists have now come up with a method that they are hailing as a game-changer for forensics, using analysis of hair samples to detect unique patterns of proteins that can identify humans up to 250 years after being left behind.
