Nature Solved It First

A fragile seashell holds the secret to making materials thousands of times tougher. By mimicking the unique 'brick-and-mortar' structure of nacre, engineers are developing a new generation of incredibly strong, lightweight composites. This design principle could lead to advancements in everything from advanced body armor and shatterproof glass to more resilient biomedical implants.
