How Hair Can be Used To Track Where You've Been

Posted by samzenpus on Wednesday October 17, 2012 @02:49PM from the hair-papers-please dept.

First time accepted submitter kandelar writes "PBS recently ran a story about how some scientists are using human hair to trace where a person has been. The combinations of different isotopes in water make for somewhat unique signatures from place to place. These isotopes get placed in growing hair strands which can then be traced back to identify where a person has been."

food sources distort results by Anonymous Coward · 2012-10-17 15:00 · Score: 4, Insightful

We eat food and drink water.
Food comes from multiple sources, some transported large distances.
This will distort results significently and reduce the accuracy of the claimed results.

The 15-year logos! by Anonymous Coward · 2012-10-17 15:27 · Score: 5, Insightful

By gum, we need a meta-story that summarizes the fantastic 15-year anniversary logos that we've been enjoying this month when the celebrations come to an end.
They've been great. Middle-earth? Braille? Mysterious crypto-patterns? Imagination! Experience! Effort!
We true Slashdotters must all appreciate the effort put in; we should therefore demand a forum to discuss and congratulate the various artists.
Who's with me? Vote this post up! I'm AC, so there's no karma-whoring here! Vote this post up to show: we want a story about the logos!
