Differential interference contrast micrograph of a Micrasterias, a type of green alga called a desmid. Each cell is constructed of two semicells which are mirror images of each other. The two semice...

The time lapse movie spans fertilization, ooplasmic segregation, and early divisions in the egg of the tunicate Phalusia mammilata. Contrast is provided by both polarizing microscopy and differential...

Movie of meiosis I (diakinesis through telophase)in primary spermatocytes of the crane-fly Nephrotoma suturalis that have been experimentally flattened. Time-lapse DIC microscopy using a Nikon Micro...

DVD quality video of the Contractile Vacuole Complex of Paramecium multimicronucleatum. In vitro CVC rounding/relaxing cycles. An in vitro CV in a ruptured Paramecium cell is surrounded by cytoplasmic...

Movie of meiosis I and II in primary spermatocytes of the crane-fly Nephrotoma suturalis. Time-lapse DIC microscopy using a Nikon Microphot SA, equipped for liquid crystal polarized light microscopy...

This video shows a typical N. gonorrhoeae microcolony interacting with the tips of our micropillar force sensing device. The video is speeded 10 times (×10) and the pilars are 3 micron apart center t...

Movie of cell growth and division in cultured hTERT-RPE1 cells (telomerase immortalized human retinal pigment epithelium) using DIC optics. This movie and the stack of images used to prepare them are...

Here we have a few hours in the life of the tail, as myotomes pinch off. The elapsed time is indicated by the clock in the upper right hand corner and the counter in the lower left and corner. This v...

This video shows stationary epidermal cells with copious retrograde flow of actin. Actin-myosin networks initiate at the cell periphery and flow towards the cell body. Even though actin-nucleation and...

This video shows a cytoplast in the process of forming. Early in the sequence the cytoplast is still attached by a retraction fiber to its parent cell. As the retraction fiber breaks, the cytoplast is...
