The U.S. Sandia National Laboratories developed a new kind of
bullet that could turn anyone into a sharpshooter in a heartbeat. The four-inch projectile has small fins on its tails similar to a dart that can steer it straight toward the target. As long as you shine a laser beam to what you want to hit, the sensor on the bullet's nose can follow it, even in the midst of strong winds and even if the target is up to a mile away. The self-guided bullet was designed for
DARPA's Exacto program and will be used by the military and law enforcement agencies.
