What do you know about using stable isotopes in bird feathers to figure out where the birds have been?

Yeah, me neither! But if you'd like that to change, come on down to Cafe Semolino's in Hays next Tuesday, June 16th, as biochemist/amateur birder Dave Rintoul visits us from Kansas State University's Division of Biology. Dave's an expert at explaining arcane science topics in layman's terms and has oodles of patience, so don't hesitate to ask him about this topic: How does it work? How do we know it works? Of what use is it? What are its limitations? Why should we care?

Visit our Science Cafe website - and on Facebook - and Cafe Semolino's MySpace page!

I'm just about finished planning out the rest of the Cafes for 2009, and will start working on 2010 in a couple of weeks. What are you curious about? Let me know and I'll try to get it set up!
