SCIENCE - Scientists build material that mimics squid beak: Promising step toward safer, more comfortable implants

Researchers have turned to an unlikely model to make medical devices safer and more comfortable -- a squid's beak. Many medical implants require hard materials that have to connect to or pass through soft body tissue. This mechanical mismatch leads to problems. But the beak, which boasts a mechanical gradient that can act as a shock absorber, may provide a solution.
