Today in 'things that will one day squeeze the life out of you after you smart off one time too many to our coming robot overlords' news: this new robotic hand from DARPA. The mechanical limb can grip things as small as a ball bearing, lift objects as heavy as a 50-pound kettle bell, and doesn't so much as flinch when you give it your best shot with a baseball bat.
Swimming pools accomplish two things: They provide a source of cooling relief from the oppressive heat of the summer sun and demonstrate mankind's dominion over a once unstoppable natural element in a rigid, confined space. The only drawback to owning a pool, however, is that within the blink of an eye, nearly every piece of dirt, trash, microbe, dead insect, and other contaminants can transform any pristine summertime oasis into a stagnant cesspool of filth. As humans, we've advanced beyond manually cleaning up these messes ourselves, as well as hiring and paying others to do a job they obviously won't do any better than we can. Always pandering to our sense of hubris and desire to be served, iRobot has recently unveiled Mirra 533 -- a pool-cleaning robot that gladly does what we people refuse to do.
