Emerging technologies help researchers draw mechanistic links between metabolism and epigenetic modification of DNA.

Some viral pathogens modify chromatin and other epigenetic machinery, making them appealing drug targets.

Unlike animals, plants stably pass on their DNA methylomes from one generation to the next. The resulting gene silencing likely hides an abundance of phenotypic variation.

Multiple molecular mechanisms keep plant DNA methylation in order.

A molecular biologist ventures into entomology to use genetically modified ants as laboratory models of behavioral epigenetics.

Understanding postmortem gene expression could help researchers improve organ transplants and time-of-death estimates, according to studies on mice and zebrafish.

Differential expression of a chromatin-interacting protein is linked to weight variation in mice and humans, researchers show.

DNA isn’t the only decorated nucleic acid in the cell. Modifications to RNA molecules are much more common and are critical for regulating diverse biological processes.

Additions to the bases of RNA molecules can be written, read, and erased.
