We already knew that select scientists were working up an advanced electronic nose, but now a team at Rockefeller University has apparently figured out a way to actually see smells. Supposedly, these gurus closely investigated fly larvae and found that sensing odors "in stereo" enabled flies to navigate to smells much more effectively than when only one olfactory organ was used. As they studied said phenomenon, the researchers used a "novel spectroscopic technique that exploited infrared light to create environments where they could see, control and precisely quantify the distribution of these smells." Impressive though this may be, we still prefer the ole GPS method to locating our favorite fare, but beholding those delightful aromas could certainly help out in a pinch.
