Name: Obama: U.S. Should Lead Assault on Climate Change by SciFri
Duration: 12 min 20 s
Description: This week President Obama announced his plan to tackle climate change, including proposals to regulate gas and coal emissions, and brace the nation for rising seas. David Roberts, who covers energy and climate change for Grist.org, talks about what to expect from the plan—and how much the president can accomplish without the help of Congress.

#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.

For the Lowly Incandescent Bulb, a Ray of Hope
