Is Sense of Smell Powered by Quantum Vibrations?

SciAm.com : Physicists have now analyzed the proposed mechanism linking a sense of smell with molecular vibrations and deemed it plausible. The new calculations by no means prove the theory, but they give it added legitimacy, says biophysicist and perfumer Luca Turin, who developed the idea. “Most people would probably feel that if it can be done at all, evolution has managed to make use of it.” A paper explaining the research appears in Physical Review Letters.
