When you're spending hours tracking the activity of spy drones, it can be hard to stay alert, even if you've got Red Bull. Now, the military is testing a caffeine alternative, and it involves the unlikely tactic of shocking drone operators' brains, the Boston Globe reports. The results so far? "We found that people who receive the stimulation are performing consistently," says a researcher in charge. In fact, after tests which sometimes lasted hours, participants were still alert, "just like they were at minute one."
The tests involve small, precise amounts of current which effectively induce miniature seizures, the Globe explains. Side effects so far include minor headaches; experts are still exploring the effects of long-term, regular use. That's just one of the questions that remain. It's also difficult "to know what to turn on and what to turn off" within the brain, says another expert. "It is a really exciting idea, but it is slow going.” And don't expect your local Starbucks to be replaced by an electroshock center: The idea is only aimed at the military. That doesn't mean civilians aren't trying similar techniques, however, as the Verge notes. (More Air Force stories.)
