       | This is awesome! The only limiter here is the resolution, I think
       | this is fantastic for cellular level organelles but it doesn't

       | diffraction does.

       | There's a huge trade off between resolution and scale that makes
       | it hard to determine things like complex molecular dynamics and
       | how those dynamics influence the broader functions of the cell.
       | 
       | That said, excited for more images like this! More data at that
       | scale is always a good thing for researchers.

         | There's a limit to how much data can be processed, resulting in

         | Now my info might be outdated since it was a few years ago, but
         | I was once told that when you use one of those microscopes, you
         | bring with you a terabyte hard drive for each specimen.
