Biochemical and genetic tests have revealed that a liver protein called NTCP is a functional receptor for hepatitis B and D viruses, which should lead to an improved understanding of the infections caused by these viruses and assist the development of new intervention strategies.

Histones bound to lipid droplets inside cells offer protection against bacteria in flies, and possibly mice, thus suggesting a possible new innate immunity pathway.

Cleavage of a membrane-bound transcription factor by the chemotherapeutic reagent doxorubicin can block the proliferation of tumor cells.

A combination of single-molecule imaging and an in vitro model of the cell cortex has allowed the interactions between actin filaments and filaments made of myosin II to be studied in detail.

Novel imaging experiments suggest that fruit flies modify their neural circuitry for walking at slow, medium and fast speeds, and that proprioception is not essential for coordinated walking.
