Physicists captured the first images of individual atoms freely interacting in space. The pictures reveal correlations among the 'free-range' particles that until now were predicted but never directly ...

Atoms measure roughly 0.1 nanometers across, a scale so small that scientists spent more than six decades developing instruments capable of resolving them with any clarity. The journey from the first ...
