Backyard Brains (Motto: "Neuroscience for Everyone!"). The first one was pretty lab-oriented, with a twitching roach leg here and there. This one has more roaches, with most of them crawling on command. Will the DoD see this and decide to make cockroach soldiers? Or roboroach bomb detectors and defusers? Or cockroach drone pilots? Anything's possible these days. But meanwhile, relax and enjoy learning about roboroaches and watching how, with little circuit boards on their little backs, they scurry hither and yon under control of their human masters. WARNING: Excessively squeamish people should not watch this video, but should stick to the transcript.
