This is wild: a team of Israeli scientists developed a contraption that uses a person's brain waves to remotely control DNA-based nanorobots -- while the nanobots were inside a living cockroach. When prompted by a human thought, the clam shell-like robots opened up, revealing a drug-like molecule that tweaked the physiology of the cockroach's cells.

Tiny mind-controlled nanobots that can be injected into the human body and directed by a doctors' thought could be used to treat diseases in the future. Scientists have for the first time used thought alone to control nanorobots inside a living creature after getting them to release a drug inside cockroaches. They say the technology could be used to treat brain disorders such as schizophrenia, depression and attention deficit disorder. Scientists have created tiny nanobots out of DNA that can carry drugs inside them. These can be controlled using computer software that detects changes in brain activity.

A man has used thought alone to control nanorobots inside a living creature for the first time. The technology released a drug inside cockroaches in response to the man's brain activity – a technique that may be useful for treating brain disorders such as schizophrenia and ADHD. Getting drugs to where they need to be exactly when you want them is a challenge. Most drugs diffuse through the blood stream over time – and you're stuck with the side effects until the drug wears off. Now, a team at the Interdisciplinary Center, in Herzliya, and Bar Ilan University, in Ramat Gan, both in Israel, have developed a system that allows precise control over when a drug is active in the body.
