I wanted to point you to a blog I read regularly, by one of those genius science types. But she's also a writer, so even I have no trouble following along. Anyway, she currently has a fascinating post about fingerprints, read it here. Full disclosure, it does include a brief interview with me, but it's much more than that.
I've also added her to my blogroll (why didn't I do that before?!). Check it out, she really knows her stuff.
