Everyone following Formula 1 knows that securing the pole position is not simple. The same is true for many proteins in rod-shaped bacteria that localize to the cell poles to function properly. I study how proteins that are important for motility in Myxococcus xanthus become localized to the cell poles.

The origin of hepatitis D virus (HDV) is currently unknown. HDV is described as an infectious agent that depends on hepatitis B virus (HBV) for envelopment and transmission of its ribonucleoprotein (RNP); yet, as shown in this study, HBV-unrelated viruses, including hepacivirus and flaviviruses, are also able to propagate HDV in vitro and in humanized mice.
