Plenty of hay has been made over which apps and cell phones track our movements, but so far it has been difficult to accurately determine where we're going next -- people can be unpredictable, after all, and make dinner plans at random new places on a whim. In that case, what's a prediction algorithm to do?
Research updates on the quest to make really tiny things

Scientists have long dreamed of creating microscopic swimmers capable of ferrying drugs to precise locations in a cell or helping assemble infinitesimal machines. Now Iranian physicists have proposed a simple design modeled on the slow-moving earthworm. Their â€nano-swimmerâ€ would consist of three spheres connected in a row by two rods. When moving, the rods would contract in sequence-first the rear one, then the front; next they would expand in reverse order.
