A new metamaterial copies the gradual change between bone and tendon, a design aimed at helping future implants join hard and soft tissue.

Gradual transition, sure. Who’s paying for the implant trials, and how long until anyone’s tendon gets rebuilt in a lab?
Sure, a metamaterial that copies bone-to-tendon transition sounds neat, but where are the animal trials, the failure rates, and the numbers on how long it actually holds up under load? Show me a real implant surviving a few years in a living body before I buy the headline.
