A Package of Dad's Genes

Just in time for Father's Day, we'll talk with a researcher studying the way genetic information is packaged inside sperm cells. Writing in the journal Nature, researchers describe special packaging materials called 'modified histones' that may help protect genes that make decisions about organ and tissue development in a developing fetus.

"Our findings show that the father plays an active role in packaging his genome to help ensure a healthy baby," Brad Cairns, a professor of oncological sciences at the University of Utah and lead researcher on the project. "They also raise the possibility that a man’s aging, health and lifestyle may alter this packaging and negatively affect fertility and embryo development." We'll talk with Cairns about the work.
