Dear Folks, I received this message from a colleague who is teaching students about the influence of corn. Do any of you alert readers have a reference at your fingertips that you could recommend for Charlie? "Next Tuesday Washington College is hosting a viewing of the movie "King Corn," which is a critique of the use of corn products in our country (see description below). One of the most fascinating things I heard about this issue was in one of your talks: The stable isotope evidence that Europeans coming to the US experience a shift in their carbon isotope ratios in response to the corn-heavy diet. Does that data appear in publication anywhere? I would love to bring that up at the viewing of this movie during the discussion period." Marilyn Fogel Dr. Marilyn L.
