Butterfly Discovered With Ears on Its Wings

blue-morpho-butterfly-webIt’s a question you wouldn’t be surprised to hear a toddler ask: Do butterflies have ears? Well yes, yes they do. And one species was recently discovered to have ears on their wings. The blue morpho butterfly from Central and South America has beautiful bright blue wings complete with a simple ear structure that picks up noise and relays it to the brain.

In the new study, Kathleen Lucas of the University of Bristol in England and her colleagues were interested in the odd-looking hearing membrane that sits at the base of the blue morpho’s wing. The tympanal membrane, as it is called, is oval-shaped with a dome at its center that kind of resembles the yolk at the center of a fried egg, Lucas said.

Researchers determined that the butterflies can distinguish high and low frequencies, uncommon in simple ears, and they speculate this could help them determine if a hungry bird is about to swoop down and attack.

golfGolf might seem like a relatively safe sport, but a new report in the British Medical Journal suggests there’s a hidden danger: hearing loss. Turns out, the loud thwaak! of the new thin-faced titanium drivers is about as loud as a gunshot or firecracker—loud enough to cause permanent hearing damage.

British doctors first tuned in to the problem after a 55-year-old male patient sought treatment for mysterious tinnitus and reduced hearing in his right ear. The doctors confirmed that his symptoms matched those of noise-induced hearing loss, although the man’s occupation didn’t involve loud noises. The puzzle finally came together when the man revealed that for the past 18 months, he’d been teeing off with a King Cobra LD titanium driver three times a week. But the sound from the club had become so irritating that he’d already ditched the club. The doctors also found other golfers online who’d had similar complaints about the “sonic boom” created by the new drivers.
