Starting out 2015 by choosing a cup of blueberry yogurt instead of some perfectly buttered blueberry pancakes probably feels like a test of willpower. But as you try to keep your new year’s resolutions, willpower is only part of the equation. What could end up undermining your goals is not your lack of discipline but your abundance of stress. The Mayo Clinic’s Dr. Amit Sood explains the effect stress can have on willpower. Plus, New York Times columnist Kit Eaton suggests apps to help you stick to your resolutions.

#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.
