Our latest article (mostly the work of the first two authors, postdoc Alex Gaitainidis and grad student Efi Drimyli) showing that flies can tell isotopes apart regardless of whether the enzymes that degrade odorants are working or not. Also that various species of Drosophila that diverged 40 million years ago are all able to smell the presence of deuterium in an odorant molecule. All evidence in favor of the fact that discrimination between normal and deuterium odorants takes place at the receptors themselves, and is evolutionarily conserved. One brick at a time….
