The Pentagon is attempting what was, until recently, an impossible technological feat—developing a high-bandwidth neural interface that would allow people to beam data from their minds to external devices and back.
That’s right—a brain modem. One that could allow a soldier to, for example, control a drone with his mind.
This seemingly unlikely piece of technology has just gotten a lot less unlikely. On Feb. 8, the Defense Advanced Research Projects Agency (DARPA)—the U.S. military’s fringe-science wing—announced the first successful tests, on animal subjects, of a tiny sensor that travels through blood vessels, lodges in the brain and records neural activity.
