“Chip-and-PIN” credit cards and mobile payments like Apple Pay and Venmo are changing the security and speed of how we transfer money. Reporters Robin Sidel, of The Wall Street Journal, and Nanette Byrnes, of MIT Technology Review, walk us through the changing technology of credit cards and mobile payments and what the trend means for consumers.

#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.
