title: CHEMISTRY: Crystals Branch Out Into Exotic Shapes.
abstract: Researchers recently managed to steer crystal growth to make thin rods by controlling the speed at which various faces of crystals grow. Now, a team has elevated this control to an art form, enabling them to make nanosized versions of a variety of shapes including rods, arrows, teardrops, and even four-armed tetrapods shaped like a child's jack.
