| Posted: 06 Jul 2015 09:37 AM PDT For the first time, Harvard researchers have created wakes of light-like waves moving on a metallic surface, called surface plasmons, and demonstrated that they can be controlled and steered. The creation and control of surface plasmon wakes could lead to new types of plasmonic couplers and lenses that could create two-dimensional holograms or focus light at the nanoscale.  |
| Full sky map: Rings and loops in the stars Posted: 06 Jul 2015 08:44 AM PDT A ring of dust 200 light years across and a loop covering a third of the sky: two of the results in a new map from the Planck satellite.  |
| Autonomous taxis would deliver significant environmental and economic benefits Posted: 06 Jul 2015 08:41 AM PDT Imagine a fleet of driverless taxis roaming your city, ready to pick you up and take you to your destination at a moment's notice. While this may seem fantastical, it may be only a matter of time before it becomes reality. And according to a new study such a system would both be cost-effective and greatly reduce per-mile emissions of greenhouse gases.  |
