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.

A protein that can recognize regions of DNA with a high proportion of unmethylated CpG dinucleotides, and then recruit polycomb group proteins to these CpG islands, has been identified.
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.
Neurons in the hippocampus modulate the rates at which they fire, and the locations in which they fire, so as to encode the information that is central to forming memories about personal experiences.
The Notch signaling pathway has a central role in the development of the nervous system, and also in the establishment of networks of connections in the adult brain
A protein complex that enables cells to transport substances across their membranes, and that typically consists of four subunits, can also function as two hemicomplexes, each with two subunits.
