Cover of Single-Molecule Techniques (IMAGE) Cold Spring Harbor Laboratory Caption Molecular motors (green, string-like objects) move cargo (bubbles) by walking on "highways" (microtubules; in red and yellow). Using single-molecule technologies, scientists can watch cargo move within the cell to gain a better understanding of cellular processes. (Image by Precision Graphics.)
