Altering DNA methylation in a particular area of the hypothalamus halved the animals’ voluntary exercise as adults.

Using CRISPR and other tools, scientists are modifying DNA methylation, histone marks, and other modifiers of gene expression to understand how they affect health and disease.

A study of chemical tags on histone proteins hints at how the same genome can yield very different animals.

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.
