Researchers Announce The First Cartilage-Mimicking Gel That's Strong Enough For Knees


That combination of soft-yet-strong has been hard to reproduce in the lab—but now, Duke University researchers say they've created an experimental gel that's the first to match the strength and durability of the real thing.

The material may look like a distant cousin of Jell-O—which it is—but it's incredibly strong. Although 60% water, a single quarter-sized disc can bear the weight of a 100-pound kettlebell without tearing or losing its shape.

Developers say it's the first hydrogel—materials made of water-absorbing polymers—capable of withstanding tugging and heavy loads equally as well as human cartilage, without wearing out over time.
