Engineers find a way to win in laser performance by losing

To help laser systems overcome loss, operators often pump the system with an overabundance of photons, or light packets, to achieve optical gain. But now engineers have shown a new way to reverse or eliminate such loss by, ironically, adding loss to a laser system to actually reap energy gains. In other words, they've invented a way to win by losing.

Light bending material facilitates the search for new particles

Particle physicists have a hard time identifying all the elementary particles created in their particle accelerators. But now researchers have designed a material that makes it much easier to distinguish the particles. The material manipulates the Cherenkov radiation from particles with high momentum so that they get a distinct light cone angle.

Future computers could be built from magnetic 'tornadoes'

Magnetic materials form the basis of most hard disc drives as they are able to store data. Engineers have been investigating whether they could also be used to perform calculations, and so take on the role of a computer's central processing unit (CPU).
