You probably don’t give a lot of thought to squid beaks, but they actually possess a pretty interesting quality. While the end of the beak is hard and sharp, the beak material gradually becomes softer as it nears the mouth. This means that there’s no abrupt boundary between the hard beak and the soft mouth, which could result in discomfort or injuries. Inspired by the squid, scientists at Ohio’s Case Western Reserve University have now developed a material with the same qualities, that could be used to create more comfortable, less harmful medical implants.
