Scientists at IBM's Almaden Research Center have developed a nanofluidic device that they say emulates the way the brain operates, using ionic currents to move data through the device. The advance could prove crucial in the development of ultra-low-power semiconductors, this blog post notes. "I'm particularly excited by our findings, because a lot of how the brain operates is by the flow of ions and ion channels. In some sense what we want to do is mimic those components of the brain," said IBM's Stuart Parkin.
