Fruit Fly Odor Receptors Found

Although researchers identified the receptors mammals use to detect odors almost a decade ago, they've been unable to sniff out those of any insect. Now, the impasse has been broken. Two teams, one led by John Carlson of Yale University and the other by Richard Axel of Columbia University, have independently discovered the first odor receptors in the fruit fly, Drosophila melanogaster.
