The researchers said "We're arguing that Brown really had discovered the secret of life ... When you get into this sub-cellular level on the nanometer scale, the dynamics and vitality of protein molecules is really due to thermal motion." The implications for nanotech are obvious."
The perversity of nature is nowhere better demonstrated by the fact that, when
exposed to the same atmosphere, bread becomes hard while crackers become soft.
