How one person can control a swarm of 130 robots

Last November, at Fort Campbell, Tennessee, half a mile from the Kentucky border, a man operated a swarm of 130 robots. Roy, including unmanned aerial vehicles, quadcopters and ground vehicles, scouted the fake buildings of the Cassidy Range complex, creating and sharing information visible not only to the human operator but also to other people … Read more

A ‘Pristine’ Reef of Rose-Shaped Corals Was Just Found Off The Coast of Tahiti

Scientists have discovered a huge reef of “untouched” rose-shaped corals, apparently unharmed by climate change in deep water off the coast of Tahiti, UNESCO said on Thursday. Planning approximately three kilometers (two miles) long and up to 65 meters (213 feet) wide, UNESCO said it was “one of the most extensive healthy coral reefs in … Read more
