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

Newly developed techniques could propel a field already advancing rapidly to complement modern medicine.

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

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.

Multiple molecular mechanisms keep plant DNA methylation in order.
