Nanotechnology still hasn’t produced the self-mowing lawn that it promised me, but researchers are slowly making progress in the ten-atoms wide world.

The University of Edinburgh has developed a surface made of molecular machines that can move a droplet of liquid when stimulated by UV light.  While it seems trivial, this incredible breakthrough in the moving-droplets-slightly-to-the-left industry has shown that nanotechnology can be used to do work on a macroscopic scale, which is the scale that my lawn lives in.

Here is a video of a droplet moving 1mm up a 12 degree incline.
