After years bubbling under the success radar, Pixel Qi has revealed a large high-resolution screen that works indoors and outdoors with equal ease. If it succeeds, it could change how and where you use computers

A team of researchers at MIT has found a way to manipulate both the thermal conductivity and the electrical conductivity of materials simply by changing the external conditions, such as the surrounding temperature. And the technique they found can change electrical conductivity by factors of well over 100, and heat conductivity by more than threefold.

If there's something aflame in your neighborhood, you may soon call for firemen toting backpacks blasting bursts of electricity to snuff out the firey problem. You listening, Bill Murray? Remember Ghostbusters ?

How fast an intense laser pulse can change the electrical properties of solids is revealed by researchers from Kiel University in the current edition of Nature.

The properties of a material are greatly affected by the electrical and magnetic structure of its constituent ions and electrons. In a ferromagnet, for example, neighboring electron spins point in the same direction, producing a strong external magnetic field
