Nature Solved It First

The porcupine quill offers a masterclass in mechanical engineering, combining two contradictory functions into one efficient tool. Its microscopic barbs don't just anchor it in place; they also help it pierce tissue with minimal force. This dual-action mechanism is now inspiring researchers to create new medical adhesives. These bio-inspired tools could hold wounds together more securely and with less tissue damage, potentially dissolving in the body once the healing is done.
