Aside from the stings and ruined picnics, fire ants are famous for their ability to swarm together and self–assemble bridges, ladders, and even floating rafts. Researchers have now figured out the statistical rules that govern how fire ants form these structures, and the new study could help scientists build swarming, tiny shape-shifting robots.
Researchers have created a new device that can trigger partial limb regrowth in frogs. The findings could lead to limb regeneration in mammals somewhere off in the future.
To survive in the Mesozoic era, dinosaurs had to do a lot of running. Whether it was to get some dinner or to not become lunch, they had to be able to break into a sprint at a moment’s notice. Supposedly, dinosaurs like the Velociraptor could run as fast as 40 mph.
