#ExplainTheSun  - The Largest Migration on The Planet

What if we lived in a world where gender was more like hair color — something you could change at will, and that had little bearing on what other people thought of you?

In her new book, Reclaiming Conversation, Sherry Turkle examines how smartphones and social media have crowded out real conversation. She says “human relationships are rich, messy, and demanding. When we clean them up with technology, we move from conversation to the efficiencies of mere connection.” Turkle explores the power of face-to-face conversation in a time of “always on”technological connection.

Sherry Turkle: Reclaiming Conversation

Ever sit down on a city park bench and immediately notice your shoulders relax? Or feel your heart begin to pound as you navigate a tricky, crowded intersection? If so, then you know the power of the built environment to affect our bodies, brains, and behavior.

Cognitive neuroscientist Colin Ellard has made a study of how our city grids, storefronts, and streetscapes shape us. He’s led volunteers outfitted with sensors on walking tours through cities like Berlin and Mumbai, and watched subjects navigate virtual green spaces in his VR lab. Ellard joins Ira to talk about how we can measure the physical and mental effects of our streetscapes—and use that knowledge to build better.

What would it be like if we lived in a world where everything you do is subject to a rating dolled out by a combination of machines and other people?

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.
