This story popped up on Slashdot today. Two artists have played back the recordings of brainwave activity of people in REM sleep on robots. Essentially the robot will act out the “in-dream” actions of the sleeping person. Pretty cool! Original story is here. A link to the video is below:

Cool paper in nature today from the research group of Prof. Z.L. Wang at Georgia Tech. They’ve made arrays of nanowire fibre’s from which they can generate (obviously small amounts of) electricity. Pretty neat nevertheless. Reminds me of this cool research that came out of Cornell a few years ago that used trace amounts of radioactive material near a micron-scale cantilever as a battery.

Came across another application of Kalman Filtering here in a homebrew UAV project.
