Physicists Unlock Nature of High-Temperature Superconductivity

July 28, 2014 8:24 pm | by University of Illinois at Chicago | Comments

Physicists have identified the "quantum glue" that underlies a promising type of superconductivity -- a crucial step towards the creation of energy superhighways that conduct electricity without current loss. The earliest superconducting materials required operating temperatures...

Refrigerator Magnets

July 28, 2014 2:02 pm | by MIT | Comments

The magnets cluttering the face of your refrigerator may one day be used as cooling agents, according to a new theory formulated by MIT researchers. The theory describes the motion of magnons — quasi-particles in magnets that are collective rotations of magnetic moments, or “spins.” In addition to...

Measuring the Smallest Magnets

July 28, 2014 1:54 pm | by Weizmann Institute of Science | Comments

Imagine trying to measure a tennis ball that bounces wildly, every time to a distance a million times its own size. The bouncing obviously creates enormous “background noise” that interferes with the measurement. But if you attach the ball directly to a measuring device...

Building 'Invisible' Materials with Light

July 28, 2014 1:49 pm | by University of Cambridge | Comments

A new method of building materials using light, developed by researchers at the University of Cambridge, could one day enable technologies that are often considered the realm of science fiction, such as invisibility cloaks and cloaking devices. Although cloaked starships won't be a reality for quite some time...

Superconductivity Could Form at High Temperatures in Layered 2D Crystals

July 28, 2014 1:45 pm | by University of California - San Diego | Comments

An elusive state of matter called superconductivity could be realized in stacks of sheetlike crystals just a few atoms thick, a trio of physicists has determined. Superconductivity, the flow of electrical current without resistance, is usually found in materials chilled to the most frigid temperatures, which is impractical for most applications...
