Worm Love (IMAGE) Princeton University, Engineering School Caption "Worm Love" was submitted by Maria Ciocca, a graduate student at University of Pennsylvania who works in a lab that studies the process of asymmetric cell division in the development of model organisms, such as the nematode Caenorhabditis elegans, pictured here. In the process of using immunofluorescence microscopy to study the one- and two-cell stage embryo of this organism, occasionally the slides will contain fully developed worms that were not properly removed in the fixation process. Typically these worms are not imaged and processed -- in fact, they do not usually retain a recognizable form.
