In 1991, researchers at New York University managed to forge a DNA cube, the first three-dimensional nanoscale object in which the position of each atom was programmed, defined, and known. DNA nanotechnology has since left its childhood behind and entered adolescence, and the field is growing in strength and power. It's now churning out applications that are helping researchers map the atomic structure of proteins and compute inside cells (see sidebar), and soon may even start tracking and curing diseases.
