New way to filter light: May provide first directional selectivity for light waves

New way to filter light: May provide first directional selectivity for light waves
But now, for the first time, researchers have produced a system that allows light of any color to pass through only if it is coming from one specific angle; the technique reflects all light coming from other directions. 

Solar system has a new most-distant member
New work reports the discovery of a distant dwarf planet, called 2012 VP113, which was found beyond the known edge of the Solar System. This is likely one of thousands of distant objects that are thought to form the so-called inner Oort cloud. The work indicates the potential presence of an enormous planet, not yet seen, but possibly influencing the orbit of inner Oort cloud objects.
