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 combination of advanced optical imaging and cryogenic electron microscopy has been used to explore membrane fusion in a synthetic system and provide new insights into neurotransmitter release.

Structural and functional studies of a potassium ion channel that is opened and closed by different ligands have revealed a novel gating mechanism.

The nematode worm C. elegans consumes familiar bacterial species more rapidly than it does novel ones, and this preference for familiarity is mediated by a pair of serotonergic neurons.

Long-lived intermediate states formed by glycoprotein catalysts are an essential part of the process used by influenza virus particles to infect cells.

The Notch signaling pathway has a central role in the formation of the circuit that controls egg-laying in the nematode worm C. elegans.

Experiments on synthetic models of synaptic vesicles have shed new light on the role of the protein α-synuclein in the central nervous system.

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.
