Electron Microscopy of Single Cell (IMAGE) Aarhus University Caption Electron microscopy picture of a single cell (in green color) isolated from the subsurface seabed in Aarhus Bay. The cell is isolated on a membrane filter with pores that are 0.2 micrometer in diameter. The researchers use highly sensitive molecular biology techniques to sequence and map the genomes of microorganisms inhabiting subsurface seabed one cell at a time. Credit Photo: Stefan Braun.
