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.

Mathematical modeling shows that local populations of the malaria parasite self-organize into a limited number of transient but distinct strains through competition for hosts in immunity space.

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

A combination of direct-electron detectors and statistical movie processing allows ribosome cryo-EM structures to be determined to resolutions that were previously only attainable by X-ray crystallography.

The structure of a large hydrogenase complex involved in the production of methane by microbes has been determined with cryo-electron microscopy.

Sensory neurons in the olfactory system develop from two different regions of the ectoderm, the olfactory placode and the cranial neural crest, whereas sensory neurons within the eye and ear develop from just one region.

Proteins produced by mast cells modulate the permeability of blood vessels, and may determine whether patients infected with dengue virus develop life-threatening complications.

A protein called PVRL4 has a central role in a number of cancers that originate in epithelial tissue, and anti-PVRL4 antibodies could be used to treat some of these cancers.

The ability of Manduca moths to recognize changes in the profile of volatile compounds released by plants being attacked by Manduca caterpillars allows them to lay their eggs on plants that are less likely to be attacked by insects and other predators, and to avoid competing against other caterpillars of the same species for resources.

A lipid acts to promote the development of nematode worm larvae through activation of an enzyme complex called TORC1.
