The images of the smallest bacteria to have ever ‘existed’ on our planet have been captured on microscope by researchers from the Lawrence Berkeley National Laboratory under the U.S. Department of Energy and University of California. The paper was published in the journal Nature Communications.
This cryo-electron tomography image, obtained from a 3-D reconstruction, of one of the cells. The interior of the cell looks densely packed. The darker spots are probably ribosomes. Scale bar: 100 nanometers. (Photo credits: Berkeley Lab)
