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

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.

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

A combination of cellular, biochemical, genetic and genomic techniques have revealed a new molecular player in the production of fat cells in mice, which could improve our understanding of obesity.

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.

Sugar levels in leaves act as a signal for plants to switch from their juvenile to their adult form by regulating the expression of two genes.

A small RNA molecule called miR-124 controls pheromone production and sexual behaviour in Drosophila by regulating sex-specific gene expression in males.

Components of the nuclear pore complex share structural and functional features with soluble nuclear transport receptors, which suggests that there may be an evolutionary relationship between these two types of protein.

Longevity in C. elegans is influenced not only by insulin/IGF-1 signalling, but also by CAMKII and calcineurin, acting on the same target, the transcription factor DAF-16.

Parallel branches of the ERAD pathway regulate sterol synthesis at multiple steps via feedback inhibition.
