In a single experiment, scientists can decipher the entire genomes of many patient samples, animal models, or cultured cells.

The epigenetic modification, DNA methylation, is characterized by 5-methylcytosine (5-mC) and found in specific genomic locations, most notably regulatory regions such as promoters and enhancers.

Smithsonian researchers used fecal samples to identify specific wild swift foxes. This method allows for non-invasive monitoring, which reduces stress for the animals. Wes Overvold, Smithsonian’s ...
