Researchers have charted patterns of DNA methylation — a chemical alteration to DNA that modifies gene expression — in the planning center of the brain from before birth to old age. The results were published 10 February in The American Journal of Human Genetics.

A new study reveals the three-dimensional structure of fruit fly chromosomes, which groups together active and inactive genes. The results were published 3 February in Cell.

A new microscope allows researchers to capture the movement of tiny signal-receiving branches in the brains of adult mice at the nanoscale level. The results were published 3 February in Science.

An automated instrument can reconstruct fluorescently labeled mouse brains in less than a day, researchers reported 15 January in Nature Methods.

Researchers have mapped the levels of tiny RNA fragments that regulate gene expression in specific brain regions and subtypes of neurons. The results were published 12 January in Neuron.
