I'm all for getting hands-on when learning about science, but I'm not sure how I feel about involving living creatures in that. Tomorrow, neuroscientist Greg Gage will publicly demonstrate RoboRoach: a DIY neuroscience kit that lets you plug into a live cockroach's antennae, and control its movements with your mobile phone.
Greg says RoboRoach will get students interested in neuroscience, and teach them critical thinking skills. He also says that the cockroaches don't feel pain, and eventually regain free will. He seems to take their welfare seriously, but I still feel it's cruel.
