Researchers are studying antlers, with the goal of building stronger helmets; they are looking at a species of fly that has acute hearing, with a view toward improving hearing aids; and they are examining the wing feathers of owls, with the idea of improving stealth airplanes.
Navorsers bestudeer dierehorings, met die doel om sterker helms te maak; hulle ondersoek ’n vliegspesie wat ’n baie goeie gehoorsin het, omdat hulle gehoortoestelle wil verbeter; en hulle bestudeer die vlerkvere van uile, sodat Stealth-vliegtuie verbeter kan word.jw2019 jw2019
