Thought-Controlled Nanobots in Cockroaches

Researchers in Israel have come up with a new type of brain-machine interface that enables a human operator to control nano-meter-size robots in a cockroach by brain activity. They use "DNA origami robots" tethered to metal nanoparticles to trigger the delivery of a drug or "bioactive payload." They say their achievement has potential implications for the treatment of such difficult-to-treat disorders as schizophrenia, depression, and attention deficits.
