DARPA is always on the lookout for the newest, zaniest gadgets but this time, we think it's gone too far. According to the Department of Defense's recent blog post, the military is interested in developing remote control techniques using ultrasound... for soldiers. Arizona State University neuroscientist William Tyler has been working on the project for several years, and now, DARPA is getting involved as well. Tyler and his team have developed a transcranial pulsed ultrasound capable of stimulating brain circuits from outside of the brain, and it can target deeper parts of the brain than past devices. The prototypes are small enough to be placed inside of a helmet, and the plan is to improve its spatial resolution with DARPA's new infusion of funding. We know they're probably looking to do cool stuff like make soldiers think they're nice and cool when they're actually frying in the sun, but we can't help but get the creeps from this one.
