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.

Cleavage of a membrane-bound transcription factor by the chemotherapeutic reagent doxorubicin can block the proliferation of tumor cells.

Novel imaging experiments suggest that fruit flies modify their neural circuitry for walking at slow, medium and fast speeds, and that proprioception is not essential for coordinated walking.

Cauliflower mosaic virus reacts immediately when aphids feed on the host plant, and this boosts its chances of being taken up and transmitted by the insects to a new plant.

The HITS-CLIP sequencing method is used to demonstrate that cryptic exons can detect messenger RNA that contains nonsense mutations, and then cause this RNA to decay, which shows that these exons are involved in maintaining the electrical balance of neurons and, possibly, preventing epilepsy.

Changing the order in which presynaptic and postsynaptic cells are repeatedly activated can change what a mammalian visual cortex neuron communicates to downstream neurons.

The enzyme that collaborates with ubiquitin ligases to promote the release of defective polypeptides from stalled ribosomes in a process named ribosome-associated degradations has been identified as the ATPase Cdc48.

A bacterial protein can be programmed with short RNA molecules to stimulate genome editing at specific sites in human cells.

The nematode worm C. elegans consumes familiar bacterial species more rapidly than it does novel ones, and this preference for familiarity is mediated by a pair of serotonergic neurons.
