Not all of nature’s layered structures are tough as animal shells and antlers

Engineers looking to nature for inspiration have long assumed that layered structures like those found in mollusk shells enhance a material’s toughness, but a study shows that’s not always the case. The findings may help engineers avoid ‘naive biomimicry, the researchers say.

With the right kind of international support — that listens to locals and generates creative solutions — communities can implement policy that will make positive change.
