Why steam burns are particularly vicious

Even if the wound looks superficially harmless, steam burns must be cooled persistently. Empa researchers have now been able to show for the first time how hot steam achieves its vicious effect: It penetrates the upper skin ...

Jellyfish-inspired electronic skin glows when it gets hurt

Electronic-skin technologies for prosthetics and robots can detect the slightest touch or breeze. But oddly, the sensors that make this possible do not respond effectively to a harmful blow. Now researchers report in ACS ...

3-D-printed 'bionic skin' could give robots the sense of touch

Engineering researchers at the University of Minnesota have developed a revolutionary process for 3D printing stretchable electronic sensory devices that could give robots the ability to feel their environment. The discovery ...

Mathematical models explain how a wrinkle becomes a crease

Wrinkles, creases and folds are everywhere in nature, from the surface of human skin to the buckled crust of the Earth. They can also be useful structures for engineers. Wrinkles in thin films, for example, can help make ...

UN hails 25-year ozone treaty for preventing disaster

The United Nations treaty to protect the ozone layer signed nearly 25 years ago prevented an environmental disaster, a chief UN scientist said Friday, cautioning though that the Earth's radiation shield is still under threat.
