Monkey Brains and Virtual Photons

In a new demonstration of the plasticity of the human brain, researchers have now shown that monkeys can quickly learn to redirect their brain activity to drive paralyzed muscles through a brain-computer interface. Cool stuff. Apparently you can do quite a bit with a single brain cell.

I also just learned the theory behind the stiction effect in microdevices. Apparently virtual photons are constantly being formed everywhere, but they can only form in spaces larger than their wavelength. So when two surfaces are very close together, fewer photons are able to form, and this results in a "negative pressure" of photons in the gap, and the surfaces get sucked together. This sounds like a good premise for a nerdy party game.
