You know what's absolutely impossible? A system going from chaos to order. You know what cells do? Turn a chaotic universe into organized, channeled motion, again and again and again. How can that be?
Your body contains natural processes that are akin to the nanomachines that we hope to build in the future — creating tiny mechanisms out of proteins that can do repair work at tiny scales. But because of the incredibly small scales and lightning fast processes of these mechanisms, we've almost never been able to see…
It may look like some diagrams and a few blobs, but what you're seeing here is nothing short of a nanotech revolution. Four nanorobots made of DNA are interacting on an "assembly line" in order to build a tiny device.
