In this issue, the news team at Science names its annual breakthrough of the year (see p. 1604). This year the honor goes to the first quantum machine—a microscopic cantilever ingeniously lowered to its lowest possible energy, the quantum ground state. The result may lead to ultrasensitive force detectors and to ways of controlling an object's mechanical vibrations as deftly as we now control electricity and light. It also heralds further investigations of one of the great mysteries of physics: the chasm separating the world of familiar objects from the bizarre realm of quantum mechanics.
