Bats Could Fly Before They Had 'Radar'

A fossil found in Wyoming has apparently resolved a long-standing question about when bats gained their radar-like ability to navigate and locate airborne insects at night. The answer: after they started flying. The discovery revealed the most primitive bat known, from a previously unrecognized species that lived about 52 million years ago. Its skeleton shows it could fly, but that it lacked...

Lab Rats May Get a Reprieve Some Day

Lab rats may one day get a reprieve. The government is studying a major overhaul of how to test the safety of chemicals, from household cleaners to pesticides. The goal is to see if robotic machinery can predict what is toxic as well as animals do. Scientists today test the hazards of chemicals for the environment mainly by injecting large doses into laboratory animals, mostly rodents....
