An anonymous reader writes "In what could be a landmark study in the new field of quantum biology, American and Greek researchers discovered that at least part of the sense of smell works using the same quantum mechanical mechanism behind flash memory and scanning tunneling microscopes — aka quantum tunneling. This research might not only open whole new frontiers in discovering and making artificial scents (e.g. perfumes, pheromones) but perhaps also "artificial noses" that can replicate the sense of smell in, for instance, nanowire detectors.
(Full disclosure: I wrote the article linked to here but have nothing to do with the research, funding, etc.)"Link to Original Source
