Light microscope images of E. coli cells in transmitted light (left) and reflected light that picks up the red fluorescence of a dye staining the cells' DNA (right). In normal cells (upper panel ...

The non-descript, pill-shaped cell is why we understand fundamental life processes (think DNA replication and transcription).

Escherichia coli bacteria imaged by high-speed inline force mapping and fluorescence microscopy. Simultaneous topography and elastic modulus maps show a stiffening of the division site. Light and ...
