Fluorescence speckle microscopy illuminates the intricate network of microtubule (yellow) and actin filament (purple) fibers that builds a cell’s structure. 
Fluorescence speckle microscopy, which tags a fraction of a protein, can improve image focus and the visibility of structures and dynamics in thick regions of living cells. Here,Credit: Torsten Wittmann, UCSF.
