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.

Electron microscopy has been used to produce the first three-dimensional image of the PRC2 gene-silencing complex.

Genome-wide measurements on mouse liver cells show that transcription, and a particular key transcription factor, have a smaller than expected influence on the mouse circadian system.

In his new book Ben Goldacre argues that the pharmaceutical industry is in poor health and in urgent need of treatment.

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.
