EMSL's Quiet Wing provides specialized space to advance research in energy, environment and biological sciences. ![Cyanothece sp. PCC 7822, a marine unicelluar cyanobacterium, imaged with a helium ion microscope located in EMSL’s Quiet Wing. This and other Cyanothece strains perform photosynthesis during the day and nitrogen fixation at night and are metabolically diverse. The image is part of a user project characterizing the cellular response network that governs bioenergy production and cell morphology of cyanobacteria under different environmental conditions. Louis Sherman, Purdue University, is the principal investigator and Himadri Pakrasi, Washington University, is co-investigator. The cells were grown and prepared by David Welkie, a graduate student in Sherman’s laboratory.
