I very much enjoyed the editorial titled "Millennial Milestones That Matter" by Dr Johns,1 which appeared in the January 2000 issue of the ARCHIVES. I would like to nominate another achievement for the past century and a goal for the 21st century. The achievement would be unlocking the basic transduction and genetic aspects of olfaction. As you are aware, olfaction as a science is in many ways behind other neurosensory developments, such as those in vision or hearing. Nevertheless, great strides have taken place in this field, especially in the past 20 years.
