An 18-carat gold nugget made of plastic

ETH researchers have created an incredibly lightweight 18-carat gold, using a matrix of plastic in place of metallic alloy elements.

A hydrogel that adheres firmly to cartilage and meniscus

EPFL researchers have developed a hydrogel – made up of nearly 90% water – that naturally adheres to soft tissue like cartilage and the meniscus. If the hydrogel carries repair cells, it could help damaged tissue to heal.

Progress Toward Artificial Tissue?

( -- For modern implants and the growth of artificial tissue and organs, it is important to generate materials with characteristics that closely emulate nature.

Researchers develop printable lasers
