Advanced light: Sending entangled beams through fast-light materials

Posted: 25 May 2014 12:53 PM PDT

Whole beams, not just particles, can be entangled. This, plus anomalous dispersion in 'fast-light' materials, allows signals be to 'advanced' over signals travelling in vacuum, at least in a limited sense.

Scientists have developed a special device for the thermogenetic control of flies. This tool, called FlyMAD, enabled the scientists to target light or heat to specific body regions of flies in motion and to analyse the animals' brain cells. Compared to other techniques, FlyMAD allows highly improved temporal resolution. Using the new technology, scientists got new insight into the role of two neuronal cell types in courtship behavior of flies.

Our research looks at how these different outcomes impact people who are friends," write the authors.
