Early Monday morning, a small drone—weighing about two pounds—crashed on the White House's South Lawn. In response to the incident, President Obama told CNN that regulatory bodies need to "make sure that these things aren't dangerous and that they're not violating people's privacy." As drones become increasingly cheap and accessible to consumers, do we have laws in place to address potential privacy concerns and violations? Ryan Calo, a law professor specializing in robotics at the University of Washington in Seattle, discusses possible ways to regulate drones and other potentially invasive technologies.

#ExplainTheSun  - The Largest Migration on The Planet

Once, there was the ordinary incandescent light bulb. It shone brightly, but wasted much of the energy put into it as heat. Then came the compact fluorescent. And as costs have dropped, consumers have increasingly been switching to light-emitting diode (LED) technology for many lighting applications, in an ongoing search for a more efficient bulb. Now, in work published in the journal Nature Nanotechnology, researchers report that nanophotonic devices may be able to breathe new life into old incandescent technology. Marin Soljačić and Ognjen Ilic, two authors of the study, explain how they’ve been able to “recycle” some of the incandescent bulb’s wasted heat and re-emit it as visible light, boosting efficiency.
