“Beware: exploding lungs” is not a sign you would expect to see near a wind turbine, but it could explain why bats are dropping dead around the machines. The risk that turbines pose to birds has long dogged the debate over wind energy. Now it seems bats face a greater risk, though why, as they can echolocate moving objects, has remained a mystery. One theory was that high-frequency noise from the gears and blades disrupted their echolocation systems.Erin Baerwald of the University of Calgary, Canada,
