The first three-dimensional visible light invisibility cloak

2014-09-29 17:07:11| Extremetech

Researchers at the University of Rochester are reporting that they've built the first invisibility cloak that works in three dimensions, viewed from a range of angles, across the full spectral range of visible light. As you can see in the photo above, and in the video below, the invisibility effect is rather effective -- and, importantly, it creates very little "telltale" distortion that usually accompanies such early attempts at cloaking (the grid lines are perfectly straight and not magnified/minimized). Best of all, though: You can make this particular kind of invisibility cloak yourself!

Gadget Ogling: Smart Wine, Wooly Sound and a Clever Light Bulb

2014-09-27 17:52:07| TechNewsWorld

I give LG a little flak for constantly releasing new smartphones, but here's one with a twist. LG is pegging the Wine Smart as its first flip-style smartphone. Yes, the compact style is back, only this time its fuel is Android, instead of whatever arcane OS manufacturers might dream up. I suspect this is more about style than function, outside of a dedicated button for opening an IM app.
