Salpinx, barbiton, aulos, syrinx. Never heard them? Never heard of them? Neither had anyone else, for centuries. Until now.

Barring the occasional thunderstorm, most Americans take the electric current behind their power buttons for granted, and assume the power will be there when they’re ready to juice an appliance or favorite tech toy.

Solar cells could soon be produced more cheaply using nanoparticle “inks” that allow them to be printed like newspaper or painted onto the sides of buildings or rooftops to absorb electricity-producing sunlight.

Applications for the arrays, which can be printed onto flat or flexible substrates ranging from glass to plastic and rubber, include general illumination, high-resolution home theater displays, wearable health monitors, and biomedical imaging devices.

New cloaking method may someday shield submarines from sonar, planes from radar, buildings from earthquakes, and oil rigs and coastal structures from tsunamis.

Researchers the world over are striving to develop organic solar cells that can be produced easily and inexpensively as thin films that could be widely used to generate electricity.

The fifth edition of Virginia Tech's Green500 List shows that supercomputers continue to use less power even as their capacity soars. Computers raking in top spots a year ago are falling by the wayside to newer models.

Using a composite metamaterial to deliver a complex set of instructions to a beam of light, Boston College physicists have created a device to guide electromagnetic waves around objects such as the corner of a building.

A giant new machine called' Oyster' designed to harness the power of ocean waves and turn it into 'green' electricity is being installed on the seabed off the Atlantic shores of the Orkney Islands.

A new class of economically viable solar power cell-cheap, flexible and easy to make,has come a step closer to reality as a result of recent work at the National Institute of Standards and Technology.
