Collecting hair: redux

Chop it off and send it in!

A couple weeks ago I posted a link to a project in which Dr. Patrick Wheatley was soliciting donations of hair for geochemical research. Intrigued, I contacted Patrick to ask him more about the hair project.

Me: What do you look for as you test the hair?

Patrick: I'm looking for changes in the ratios of isotopes in various elements. I hope to tie the changes in isotopic ratios to differences in geography, either through differences in the isotope ratios of local water supplies or fundamental deferences in the geology of the region where the hair was grown.

Me: How do those isotopes get in our hair in the first place?

Patrick: They are incorporated through our drinking water or diet.

Me: What will your findings help scientists do or understand? Is there a practical application for this research?

Patrick: This research is driven by a possible forensic application, knowing the past whereabouts of victims of crimes (perhaps dead and unable to talk about where they were or perhaps held in a secret location) or suspects of crimes (maybe unwilling to talk about where they have spent time recently). There are also possible medical applications.

You can still send hair in for the project. More information can be found at the project's website.

That is fantastic! I love this call to action. And I am so heading down to the barber shop near the museum some time this week, and asking them for a bag full of fair, for SCIENCE.
