Is Brownian Motion The Secret Of Life After All?

mindpixel writes: "unisci is reporting research from Georga Tech that suggest the the key motor protein ATP works by 'rectified browian motion' as a kind of thermally driven nano-ratchet. 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."
