A boost to your mobile signal Jan 25th 2013, 16:12 When using your mobile phone, it doesn't take much to lose that precious signal - just turning a corner or riding on a train can be enough. New research is developing new technologies to eradicate those annoying 'black holes' in wireless coverage, while freeing up some mobile network capacity at the same time. | Quantum communication: Each photon counts Jan 25th 2013, 15:40 Ultrafast, efficient, and reliable single-photon detectors are among the most sought-after components in photonics and quantum communication, which have not yet reached maturity for practical application. Physicist have now, however, achieved a decisive breakthrough by integrating single-photon detectors with nanophotonic chips. The detector combines near-unity detection efficiency with high timing resolution and has a very low error rate. | Grammar undercuts security of long computer passwords Jan 24th 2013, 17:35 When writing or speaking, good grammar helps people make themselves be understood. But when used to concoct a long computer password, grammar -- good or bad -- provides crucial hints that can help someone crack that password, researchers have demonstrated. | Grammar undercuts security of long computer passwords Jan 24th 2013, 17:35 When writing or speaking, good grammar helps people make themselves be understood.
