MELVILLE, N.Y., Sept. 22, 2006 -- Paul Appleton, a researcher from the Division of Cell and Developmental Biology at the University of Dundee in Scotland, took top honors in Nikon's 2006 Small World Photomicrography Competition for his two-photon fluorescence image of a mouse colon seen through a microscope. He was among 12 who were awarded at a reception held last night at the Helen Mills Theater in Manhattan. Cell nuclei of the mouse colon (740x), 2-photon fluorescence.
