Four cells of the alien-looking Botryo, a unicellular plankton microalga. Image take with Nikon TE-2000 with DIC optics and Nikon Elements software. Image taken by Aaron Sobel, undergraduate research student in the Bachmann lab	Fluorescently labeled pollen grains (various species). Image taken with Nikon TE-2000 with widefield multichannel fluorescence and Elements software. Image By Alex Bannigan.	Video of beating ciliated cells in turkey trachea. Click on the image to play.

Image of a living, late stage Drosophila embryo, dorsal anterior view, just prior to the head involution process studied in the Halsell lab. The actin cytoskeleton outlining individual cells is visualized by localized Green Fluorescent Protein. Imaged captured by Maureen Filak ('10) during the summer REU program. A video from some of Dr Halsell's earlier work can be seen on the Duke University Light Microscopy Core Facility's Gallery	Arabidopsis root cells expressing GFP-tubulin (green). One cell was injected with fluorescein, which has moved to cells above and below (arrowheads). Spectral imaging on the Nikon confocal was used to separate the very similar signals from fluorescein and GFP. Fluorescein has been false-colored red. Image by Alex Bannigan	A plant protoplast (cell without walls) expressing GFP (green) in the nucleus. The nucleus is also stained with DAPI (blue). The chloroplasts autofluoresce (red).
