Where have YOU been?

by Gene on May. 07th, 2008

Scientists at the University of Utah have discovered a way to read the water molecules in a person’s hair, and thereby determine where that person comes from. Hydrogen and oxygen atoms come in different forms, or isotopes, which are found in different parts of the country. As your body grows hair, it uses the isotopes it absorbed from your local drinking water. Reading the isotopes tells scientists where the person lived. This tool can be used to help identify bodies and solve missing persons cases.

You're right -- it's not an exact location, but more of a general area -- southeastern United States, for example.

But it's not your ancestors -- it's you. The water you drink contains isotopes that eventually work their way into your hair. And if you grow your hair long, the isotopes out at the end may be different than the ones near the root, if you moved since your last haircut.
