The architecture of the bacterial cytokinetic ring in cells and in artificial liposome reconstitutions has been described using electron microscopy, leading to a mechanism of constriction.

Bacterial cytoplasmic chemoreceptors assemble into a sandwich of two hexagonally packed arrays.

Bacteria produce a syringe-like structure, loaded with a single protein within the lumen of its needle-like tube, that is sufficient for stimulating animal metamorphosis.

Respiratory activity and inner membrane organisation of mitochondria from Drosophila melanogaster break down during ageing, but mouse heart mitochondria appear to be protected against age-related damage.

Structural and functional approaches unambiguously revealed physiologically relevant lateral interactions between FtsZ protofilaments.

Mammalian mitochondria in living cells store calcium phosphate in solid form.

The proteins injected by bacteria into eukaryotic organisms can lead to fates as diverse as death and metamorphosis.

The corkscrew-like motility of Spirochete bacteria is enabled by a unique, asymmetrically constructed flagellum that wraps around the cell body within the periplasm.

Cryo-electron tomography of mammalian and fly centrioles shows that the ninefold symmetry of centrioles is set by species-specific microtubule linkers.
