<jats:p>Could chemical changes to DNA underlie some of society's more vexing problems? Or is this hot new field getting ahead of itself?</jats:p>

<jats:p>The push to show that epigenetics can translate early life experiences into lasting changes in behavior has been accompanied by a parallel surge of interest in how chemical modifications to DNA can affect cognition.</jats:p>
