Name: Science of Slumber: How Sleep Affects Your Memory by SciFri
Duration: 46 min 41 s
Description: We spend a lot of time sleeping (roughly one-third of our lives, according to the National Institutes of Health). But how much downtime do our brains really need? Experts discuss the links between sleep, memory, and cognition, and why our sleep patterns change as we age.

Need to take this on board. My memory's aging!

#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
