The unparalleled liquid strength of cartilage, which is about 80% water, withstands some of the toughest forces on our bodies. Synthetic materials couldn’t match it – until “Kevlartilage” was developed by researchers at the University of Michigan and Jiangnan University. “We know that we consist mostly of water – all life does – and yet our bodies have a lot of structural stability,” said Nicholas Kotov, the Joseph B. and Florence V.

Many people with joint injuries would benefit from a good replacement for ...
