Researchers find way of developing composites that self-heal at very low temperatures
Scientists have developed a method of allowing materials, commonly used in aircraft and satellites, to self-heal cracks at temperatures well below freezing.

On an intuitive level, you'd expect a shark's skin to reduce drag. After all, the purpose of sharkskin-inspired riblets—the micro-grooved structures found in aircraft wings, wind turbine blades and Olympic-class swimsuits—is ...

When set up in groups, wind turbines in the front rows cast a wind shadow on those behind them, lowering their performance. These effects dissipate fastest under convective conditions, say EPFL researchers in a recent publication.
