Frosty P. writes "Scientists have discovered a new smell, but you may have to go to a laboratory to experience it yourself. The smell is dubbed 'olfactory white,' because it is the nasal equivalent of white noise, researchers report in the journal Proceedings of the National Academy of Sciences. Just as white noise is a mixture of many different sound frequencies and white light is a mixture of many different wavelengths, olfactory white is a mixture of many different smells. In a series of experiments, they exposed participants to dozens of equally mixed smells, and what they discovered is that our brains treat smells as a single unit, not as a mixture of compounds to break down, analyze and put back together again."

exposed to the same atmosphere, bread becomes hard while crackers become soft.
