It takes a nose to know danger!

According to researchers from Northwestern University's Feinberg School of Medicine, all it takes is one bad experience and the nose remembers the danger.

As every nose is subjected to hundreds of thousands of scents every day, some of which are almost identical, it is intriguing how we learn to distinguish the critical ones apart from each other.

Lead author of the study Dr. Wen Li, says it is evolutionary and a single negative experience linked to an odor rapidly teaches us to identify the odor and discriminate it from similar ones.
