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.

Mind alteration device makes flies sing and dance Posted: 25 May 2014 12:47 PM PDT 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.

Partners in crime: When do friends conspire to eat more chocolate? Posted: 21 May 2014 10:34 AM PDT As a human race we strive for perfection, knowing that no one is perfect. A new study offers insight into why we surround ourselves with people who help bring out our best but don't make us feel terrible when we stray from perfection. "In a situation requiring two people to use self-control, either both indulge, both abstain, or one indulges while the other abstains. Our research looks at how these different outcomes impact people who are friends," write the authors.
