High-tech imaging

Professor of Biology David Domozych won a fifth-place award in the 2009 Olym­pus Bioscapes international image contest, which drew 2,000 entries from 62 countries. His image, taken at the Skidmore Microscopy Imaging Center, is a confocal laser-scanning light micrograph of the green alga Penium, showing the effect of oryzalin, a common herbicide that weakens the cytoskeleton of plant cells. In red are the cells’ chloroplasts bursting out from the damaged cell walls.

Work by Domozych and colleagues also appears on the covers of two professional journals. The July/August Journal of Eukaryotic Microbiology shows a picture of Cosmarium reniforme, to accompany an article by Domozych, fellow faculty member Catherine Domozych, and Richard Wilson ’06, discussing the cell wall of a Cosmarium alga commonly found in Adirondack wetlands. The November cover for Annals of Botany features an image of another alga, also taken at Skidmore. It accompanies a paper, coauthored by David Domozych and two researchers at the University of Copenhagen, about cell-wall polymers in Chara corallina.

Domozych recently won a National Science Foundation grant for his research into algal cell-wall polymers. Also, he and other Skidmore scientists received more than $650,000 from the NSF to purchase an ultra-high-resolution Libra 120 transmission electron microscope, which Domozych calls “the best biological electron microscope on the market today.” Along with Skidmore biologists and chemists and their students, biomedical researchers at Albany Medical College may be among the researchers granted access to the new equipment. —PD, AW
