Epigenetic Discovery (IMAGE) University of Nebraska-Lincoln Caption As detailed in the journal <i>PNAS</i>, Nebraska's Sophie Payne and colleagues have reported the first experimental evidence of epigenetics in single-celled archaea. The simplicity of archaea, combined with the fact that their cells resemble eukaryotes' in some important ways, may allow researchers to investigate epigenetic questions in humans much faster and more cheaply than was possible before. The discovery also raises questions about the emergence of epigenetics, the researchers say.
