Hair Samples used to Trace Movement!

Ok, now THIS is amazing. Half-awake, listening to NPR this morning, I heard a bit about researchers being able to analyze a person's HAIR to trace the history of where they've been. Utah scientists have been researching isotopes in rainwater, mapping geographic differences, which show up in drinking water and food and, ultimately, in the consumer's hair structure! The Salt Lake County Sheriff's Department applied this technique to track the movements of a "Jane Doe" (whose bones were found in their area) prior to her untimely death. Sounds crazy, but apparently it's proving to be fairly accurate. You learn something new every day! (Or at least you should). Click here for the full story.
