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.
A genome-organizing protein that is present only in the olfactory system of mice has been found to orchestrate changes in the relative numbers of different odor-sensing neurons on the basis of how active these neurons are.

A protein that can recognize regions of DNA with a high proportion of unmethylated CpG dinucleotides, and then recruit polycomb group proteins to these CpG islands, has been identified.
Preventing premature interactions between microtubules and protein-based structures called kinetochores ensures that chromosomes are segregated by meiosis rather than mitosis in reproductive cells.

Experiments in mice have shown than an enzyme that repairs broken DNA inside the nucleus also has a central role in the innate immune system because it is able to detect foreign DNA outside the nucleus.
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.
