foobarx writes "Digital artists have created a humanoid robot which uses brainwave activity recorded during sleep to playback an interpretation of your dreams. The artists, Brendan Burns and Fernando Orellana used machine learning to find patterns in the brainwaves and then matched these patterns to dreams which they remembered having. Others have noted the possible hazards of this new technology."

Engadgets is reporting that researchers at Penn State have built a new kind of solar cell that can harvest hydrogen directly from water. "The folks at Penn State have now developed a process that more closely mimics the photosynthesis process in plants, and while we won't pretend to understand all the nitty gritty of dye usage and other such nonsense, we do know that such a system could eventually attain 15% or so efficiency, providing a nice and clean way to gather power for that fuel cell car of the future."
