Running an LED in reverse could cool future computers

In a finding that runs counter to a common assumption in physics, researchers at the University of Michigan ran a light emitting diode (LED) with electrodes reversed in order to cool another device mere nanometers away.

Light triggers gold in unexpected way

Rice University researchers have discovered a fundamentally different form of light-matter interaction in their experiments with gold nanoparticles.

Researchers generate optical skyrmions

Technion-Israel institute of Technology researchers have succeeded in generating minute "nano-hedgehogs of light" called optical skyrmions, which could make possible revolutionary advances in information processing, transfer ...

New bolometer is faster, simpler, and covers more wavelengths

Bolometers, devices that monitor electromagnetic radiation through heating of an absorbing material, are used by astronomers and homeowners alike. But most such devices have limited bandwidth and must be operated at ultralow ...

Engineers create stable plasma ring in open air

For the first time, engineers at Caltech have created a stable ring of plasma in open air—essentially capturing lightning in a bottle, but without the bottle.
