You know that a lot of technological breakthroughs over the decades have come straight out of the U.S. military. What were once fantastical ideas developed for warfare, like GPS and microwaves, are now everyday tech tools that we can't live without.
So, what's in store for the future? Just check out the Defense Advanced Research Projects Agency's DARPA Wait, What? conference, which took place in St. Louis last week. Maybe you heard about the cat robot that was tooling around on skateboard wheels, delivering granola bars to attendees.
Or perhaps you've seen footage of next-generation helicopters that have insect-like legs, to land on surfaces that are uneven, or moving, like on an aircraft carrier. (See video on the next page.)
But one of the most intriguing developments announced at the DARPA conference involved brains. Specifically, dozens of people were implanted with electrodes that could be stimulated to improve their memory.
