Researchers at the University of Massachusetts have discovered how nano molecules (extremely small molecules that can literally be put together by humans) can 'smell' illnesses (ns). We develop more and more technologies that allow brands to react to people. Now for illnesses (ideal for health coaching brands), but in the future social coaching brands for example could smell how we feel with other people, or career coaching brands can smell our stress in a conversation with a colleague. And help us take the next steps. This is a small step in that direction.
