"Physicists in Japan have shown experimentally that a particle can be made to do work simply by receiving information, rather than energy." It seems to be something like a demonstration of Maxwell's Demon. http://physicsworld.com/cws/article/news/2010/nov/19/information-converted-to-energy My question is: Can the conversion of information into energy work in reverse? In other words, can energy be converted to information? How would that work? Does it actually happen?
