Fusion power seeks super steels
Scientists say an understanding of how the Twin Towers collapsed will help them develop the materials needed to build fusion reactors. New research shows how steel will fail at high temperatures because of the magnetic properties of the metal.
The New York buildings fell when their steel backbones lost strength in the fires that followed [...]
Foods ’should label up eco-costs’
Food packaging could be embedded with computer chips that instantly link your phone to an on-line sustainable food guide, a UK conference has heard. The guides would help consumers navigate their way through the ethical and ecological decisions about what they eat, the proponents argue.

Elastic electronics see better
A new camera designed with a curved detection surface allows imaging devices to see as animals do. The camera, inspired by the human eye, relies on the ability to construct silicon electronics on a stretchable membrane.
In the future, these electronic membranes could be wrapped around human organs to act as health monitoring devices, say [...]
