I found this pretty interesting:
Full article HereIn April, the University of Southern California made the headlines when it announced that researchers there had created a functioning synthetic synapse circuit using carbon nanotubes. Well, today IBM unveiled a new class of experimental computer chips that are designed to emulate the human brain's abilities for perception, action and cognition. According to the company, "The technology could yield many orders of magnitude less power consumption and space than used in today's computers."
I like how whenever I hear about technology like this I always think about robots acting like people but IBM seems to only think about traffic lights.
