I was intrigued by the discovery of an artificial nose by the biological engineers at Massachusetts Institute of Technology (M.I.T) with numerous applications in the future. They suggest that their RealNose could replace drug-sniffing/explosive-sniffing dogs that are used by law enforcement officials + help doctors detect diseases that have specific smells within the human body, like diabetes/bladder/lung/skin cancers.

Smell is perhaps one of the oldest and most primitive senses, but nobody really understands how it works. It still remains a tantalizing enigma.

Could it be possible for the MIT team create an artificial eye that can identify (treated vs untreated) gemstones + grade diamonds/colored stones? Just curious.
