Adhesiveness of Staphylococcus aureus cells is unevenly distributed across the cell surface
Staphylococcus aureus, a dreaded hospital germ, can cause serious infections. One remarkable characteristic of this bacterium is its extraordinary adhesive ability. A team from the Physics and Medicine departments at Saarland University has now discovered that the germ adheres better to some parts of the envelope than to others. Their study, which has now been published, could be the starting point for more effective bacteria-repellent surfaces.

Vesicles driven by dynein and kinesin exhibit directional reversals without regulators
Intracellular vesicular transport along cytoskeletal filaments ensures targeted cargo delivery. In our recent publication in Nature Communications, we - together with the group of Stefan Diez (TU Dresden) - demonstrate that a minimal system, comprising purified Dynein-Dynactin-BICD2 (DDB) and kinesin-3 (KIF16B) attached to large unilamellar vesicles, faithfully reproduces in vivo cargo motility, including runs, pauses, and reversals.
