The Smallest Map Ever Made

Angels on heads of pins? Secret Soviet microdots? They have nothing on scientists from the California Institute of Technology.

Paul Rothemund, along with colleagues, have coaxed strands of DNA to make a shape that resembles the Americas.

This map is just a few hundred nanometers (billionths of a meter) across- a scale of 1:200 trillion.

They published their research in Nature.
