Transgenic mice with high levels of FGF21 live for longer than wild-type mice and do so without reducing food intake.

A unique form of regulation has been observed in the unfolded protein response of S. pombe, along with a novel mechanism of post-transcriptional mRNA processing.

The development of colonies of cells in choanoflagellates, water-dwelling organisms that feed on bacteria, is triggered by the presence of very low concentrations of a lipid molecule produced by certain types of bacteria.

A pattern recognition receptor called toll-like receptor 13 detects pathogens in a manner that is different to that seen in other pathogen sensors.

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.

The first survey of the complete morphologies of nerve endings in the skin of mice has revealed enormous structural diversity.
