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

A study suggests that the direct transfer of DNA methylation marks from one generation to the next is much less common than scientists previously thought.

A clock constructed of rDNA methylation sites can estimate both chronological and biological age across species.

Clinical analyses of patients’ gene sequences are helping to provide answers where none were available before.

New technologies reveal the dynamic changes in mouse and human embryos during the first week after fertilization.

The switch from maternal factors involves dynamic reprogramming of the zygotic genome.

Researchers are just beginning to scratch the surface of how several newly recognized epigenetic changes function in the genome.

To expand the basic nucleotide alphabet, many species modify their DNA with epigenetic marks.

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.
