A 2-year field study has demonstrated that volatile compounds produced by plants when they are attacked by herbivores act as defenses by attracting predators to the herbivores and increasing the reproduction of the plants.

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.

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

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

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

Intramembrane proteases identify target proteins in a different way from other proteases.

Histones bound to lipid droplets inside cells offer protection against bacteria in flies, and possibly mice, thus suggesting a possible new innate immunity pathway.

The transcription machinery used to regulate gene expression and self-renewal in human embryonic stem cells is different from that found in other cells.
