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. Lovers of gold watches and heavy jewellery will be thrilled. The objects of their desire may someday become much lighter, but without losing any of their glitter. Especially with watches, a small amount of weight can make all the difference.

Bandage material helps stop bleeding without adhering to the wound
Researchers from ETH Zurich and the National University of Singapore have developed a new kind of bandage that helps blood to clot and doesn't stick to the wound. This marks the first time that scientists have combined both properties in one material. "We did not actually plan this, but that is just how science works sometimes: you start researching one thing and end up somewhere else," says ETH Professor Dimos Poulikakos.
