Just as a postal worker knows to deliver a package to a specified address, a new type of nanoscale robot can deliver therapeutic cargo specifically to cancer cells (Science, DOI: 10.1126/sci​ence.1214081). The nanobot, made from DNA, could be used for targeted drug delivery, taking molecules to the surface of specific cells.

A robot is something that senses and reacts to its environment, explains George M. Church, the Harvard Medical School professor who devised . . .
