Great cartoon/microscopy images of how Bacillus subtilis undergoes the process of &amp;nbsp;sporulation, transitioning from a normally growing bacterial cell (left) through stages of creating a small separate intracellular compartment (second from left) which then becomes engulfed inside the larger cell (third from left), eventually maturing and being released from the dead cell (right) as a dormant and highly indestructible SPORE. &amp;nbsp;Image by David Rudner, HMS (1)
