There's a bipolar force with a repulsive side that doesn't involve cosmic opera or wooden acting - it's light. And it can be used to control components on silicon microchips, meaning future nanodevices could be controlled by light rather than electricity, according to Yale researchers. The team previously discovered an 'attractive' force of light and showed how it could be manipulated tiny switches in semiconducting micro- and nano-electrical systems. They say they have now uncovered its non-evil twin - a repulsive force. read more
