Physicists studying neutrinos figure out a previously unknown (and unsuspected) link between eigenvalues and eigenvectors that simplify the calculations in the latter.
That's kinda obscure, but it deals with mathematical operations to rotate and transform matrices of objects from the real world.
Ok. That's still obscure. But, the article doesn't say it, but this could be a real breakthrough for computer programming of simulations.

This isn't a new thing, simply easier to exploit now that everyone has a device they want to keep charged.[video=youtube;77YpxG4WPqQ]https://www.youtube.com/watch?v=77YpxG4WPqQ[/video]

Some of the video showed devices plugged into the AC outlet with a wall charger, implying that juice-jacking is possible even through an AC outlet. It's not. It's only possible if you plug your USB cable into a USB outlet. If you're using your wall charger plugged into an AC outlet, you're fine.
Yeah, I saw that or a similar pic today talking about a USB condom. The phones were plugged in using the standard charging brick, but the outlets were labeled 220V
Ughhh ... I don't think they're doing that right

Those outlets support Edison and European style plugs.That does not look like a US outlet. I’m not a well traveled man outside of the US. But I’d say that’s probably a foreign outlet with the appropriate plug on the charger. But point made, it’s not plugged straight into the USB.
Probably just a stock photo of phones plugged into a public outlet.

Same here, but if that outlet truly delivers 220V, your little charger brick won't know what hit it
Edit: I'm wro... uhhh ... I looked it up, the iPhone brick, at least, is engineered to adapt to common voltages in use throughout the (civilized) world

Bluetooth is a wireless technology and not done via cables. It has other potential security issues, but wires aren't involved.
Hacking via USB is possible because it includes both data and power wires. Using a power-only connection as pictured above means there is no USB data connection to allow problems. If you connect your device to one of the USB sockets on that wall, that's when a USB "condom" device is recommended to disconnect the data wires.
