Submission + - Sense of smell may be tied to quantum physics

SpaceAdmiral writes: "A controversial theory that says our sense of smell is based not on the shape of the molecules that enter our nose but on their vibrations was given a boost recently when researchers at University College London determined that the quantum physics involved makes sense. The theory, which suggests electron tunneling initiates the smell signal being sent to the brain, could explain why very similarly shaped molecules have very different smells."
