According to this release from the BioDesign Institute at Arizona State University,
A team of scientists from Columbia University, Arizona State University, the University of Michigan, and the California Institute of Technology (Caltech) have programmed an autonomous molecular “robot” made out of DNA to start, move, turn, and stop while following a DNA track.
The development could ultimately lead to molecular systems that might one day be used for medical therapeutic devices and molecular-scale reconfigurable robots—robots made of many simple units that can reposition or even rebuild themselves to accomplish different tasks.
Or for creating the Overmind and repairing and reanimating the thawing head of Fred Christ, the frozen god, according to diabolical villain Monty Meekman, the power behind the throne at Digital Microsystems, Inc., and chancellor of the University of New Kent, as chronicled in my famous novel Acts of the Apostles and famous novella The Pains.
