Researchers have mapped the more than 500,000 connections in the intricate brain of a fruit fly larva. This map, they say, could help scientists figure out how learning changes the human brain, too.
Scientists say Limacina helicina, which moves much like a fruit fly, represents a "remarkable" evolutionary convergence. Its ancestors and those of flying insects diverged some 550 million years ago.
Since September, Florida has been fighting an infestation of the Oriental fruit fly, an invasive pest that threatened more than 400 crops. The state declared the insect eradicated as of Saturday.
