Nature Solved It First

Nature developed a powerful adhesive that works underwater long before humans did. The sandcastle worm builds its home by gluing together bits of sand and shell, a process that has inspired a new medical glue. Scientists have replicated this natural wonder to create a biocompatible adhesive. This new material could soon be used to repair shattered bones, especially small fragments that are difficult to treat with traditional methods like screws and plates.
