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.

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 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.

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.

Structural and functional studies of a potassium ion channel that is opened and closed by different ligands have revealed a novel gating mechanism.

A combination of single-molecule imaging and an in vitro model of the cell cortex has allowed the interactions between actin filaments and filaments made of myosin II to be studied in detail.

Individual granule cells within the cerebellum-the region of the brain that coordinates movement and supports the learning of new motor skills-receive both sensory and motor input streams: an arrangement that may help the brain to use feedback to fine-tune movement.

The structure of a large hydrogenase complex involved in the production of methane by microbes has been determined with cryo-electron microscopy.

A cellular motor protein helps to ensure that microtubules are oriented correctly within neuronal dendrites
