It may look like a poster for the Grateful Dead, but these Day-Glo rainbow stripes belong to a fruit fly. Duke biologist Amy Bejsovec is studying the patterns that emerge during a fruit fly's development from egg to adult -- information that may help treat diseases that arise when normal development goes awry.
The red stripes stain a protein called Wingless, which helps cells grow and multiply and develop into different cell types. Blue marks cell nuclei. The green areas contain a protein that keeps Wingless in check -- a key factor in avoiding cancer.Image credit: Duke University
