New findings about the hard exterior of the desert locust put scientists a step closer to engineering new strong materials. Cuticle, the material making up the exoskeleton of Schistocerca gregaria, has a toughness that is comparable to natural composites such as bone, researchers at Trinity College Dublin report.
The exoskeleton of a locust, as seen under a scanning electron microscope, reveals an intentional cut (left of arrow) that propagated as a crack (right of arrow) when bent.
