...and so can an old microscope. Betzig invented PALM, which was a cool idea. This isn't. The lattice light sheet is a combination of a great idea Betzig didn't invent (light sheet microscopy) with another great idea Betzig didn't invent (structured illumination microscopy). The engineering is well done, but the fundamental idea is crap: the two techniques don't combine in an elegant way, and interfere with each other's strengths. What Betzig did exceptionally well with this paper was parlay a star-studded author list and some fancy surface-rendered time lapse movies into an extremely high-impact paper, despite a mediocre underlying accomplishment.
