A variety of imaging advancements in recent years is making it possible to study the brain in real time -- techniques such as positron emission tomography and magnetic resonance imaging. These methods are giving us insights into the way the brain behaves, but they're not without shortcomings, ranging from their invasive nature to less-than-stellar image resolution.
Scientists at the University of California, Berkeley, are investigating a completely novel approach to studying the brain in real time: smart dust.
That's right. Dust.… Read more
