For less than $40 a month, residents of Seoul, Hong Kong, Tokyo, Bucharest, and Paris can enjoy lightning-fast Internet download and upload speeds of 1,000 Mbps. Compare that to the U.S., where the same money might buy you a comparably sluggish 15 Mbps/1 Mbps connection. Even in cities like Chattanooga and Kansas City, where high-speed Internet rivals the gigabit speeds found abroad, it still costs about twice as much, according to a new report from the New America Foundation's Open Technology Institute, called “The Cost of Connectivity.”
 
The reason for America's low-speed, high-cost Internet? High-speed Internet service providers have a monopoly in many markets, says Susan Crawford of Harvard Law School. That means there's little pressure from competitors or regulators to provide better, cheaper service. But in the absence of federal action, she says, mayors around the country are leading the way.

#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.
