Better energy harvesting with 'law-breaking' device

If you take an object and set it out in the sun, it will begin to warm up. This is because it is absorbing energy from the sun's rays and converting that energy to heat. If you leave that object outside, it will continue ...

Shining a little light changes metal into semiconductor

By blending their expertise, two materials science engineers at Washington University in St. Louis changed the electronic properties of new class of materials—just by exposing it to light.

Scientists discover new type of self-healing material

A research group from RIKEN and Kyushu University has developed a new type of material, based on ethylene, which exhibits a number of useful properties such as self-healing and shape memory. Remarkably, some of the materials ...

Spider silk made by photosynthetic bacteria

Spiders produce amazingly strong and lightweight threads called draglines that are made from silk proteins. Although they can be used to manufacture a number of useful materials, getting enough of the protein is difficult ...

Cambridge to study technology's risk to humans

Could computers become cleverer than humans and take over the world? Or is that just the stuff of science fiction? Philosophers and scientists at Britain's Cambridge University think the question deserves serious study. A ...

NASA satellites see Super-Typhoon Haiyan lashing the Philippines

Super-Typhoon Haiyan was lashing the central and southern Philippines on Nov. 7 bringing maximum sustained winds of a Category 5 hurricane. NASA is providing visible, infrared and microwave satellite data to forecasters and ...
