One-Molecule Nanocar Takes a Test Drive

MrSeb writes "Just a couple of months after nanoengineers at Tufts University developed an 18-atom single-molecule electric motor, researchers from the University of Twente in the Netherlands have gone one better: They've made a car using just a single molecule. To create the vehicle, Tibor Kudernac and colleagues crafted a molecule with a long body and four 'paddle' (wheel) features attached at each corner. The molecule was created with a bottom-up process, where each part of the molecule is gently slotted together. By applying tiny amounts of electricity with a scanning tunneling microscope (STM) to the finished vehicle, the wheels are forced to make a quarter turn. The wheels naturally take another quarter turn to restore equilibrium — and then the STM starts the process all over again. The end result is very slow forward movement — six nanometers per 10 electric pulses."

      mechanically it'd be doable. I don't think so much on the DNA or neural level. How much of the so-called "junk" DNA is actually junk? Just the bits that haven't been patented yet? As for nervous tissue: it is estimated that less than 4% of the brain is actually used in the most genius of us, but what of the rest? What is it actually used for if not mechanical control, thought processes, storage, etc? We just don't know, ergo we don't know how much we can prune before we make the transition from Homo sapiens to Cyanea capillata.

    1 molecule does not imply that it is less than 18 atoms. From looking at the fucking article I can see that they have used much more than 18 atoms. Fuck this shitpost.
