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

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

Virtual reality experiments show that motorists slow down when driving in fog, but they speed up when visibility is reduced equally at all distances.

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.

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

A chromatin boundary factor that is only active during early embryo development has been discovered in Drosophila.
