Hartmanella vermiformis. Color enhanced scanning electron micrograph of cysts of the protozoan Hartmanella vermiformis on a laboratory-grown potable water biofilm. Aquatic bacteria were grown as biofilm on steel for one week. Hartmanella vermiformis protozoans were then added, and phagocytized the bacteria that multiplied within vesicles that became cysts in which the bacteria will live until they rupture.

This scanning electron microscope (SEM) image revealed two Acanthamoeba polyphaga protozoa, as they interacted through their numerous pseudopodia, projecting from the surface of these organisms. These pseudopodia allow amoebas to move and grasp objects in their environment. In this particular case, it was not known whether these two amoebas were communicating, or coming to the conclusion of mitotic cell division, becoming separate organisms.

Under a relatively low magnification of 200X, this digitally-colorized scanning electron micrograph (SEM) of an untreated water specimen extracted from a wild stream mainly used to control flooding during inclement weather, revealed the presence of unidentified organisms, which included bacteria, protozoa, and algae. In this particular view, number of what appeared to be rod-shaped sections of various sizes were scattered throughout the field of view, which though unconfirmed, may have been vege

Cultured hippocampal neurons grown on a substrate of glial cells (astrocytes). The glial cells form the pink/brown underlayment in this image. The tan threads are the neurons. The round tan balls are synapses, the points where neurons meet and communicate with each other. The cover slip underlying the cells is green. Neurons in culture can be used to study synaptic plasticity, activity-dependent protein turnover, and other topics in neuroscience.
