Scientists discovered a new gene family on the Y chromosome of deer mice, challenging the belief that the chromosome only ...

A study led by bioengineers at the University of California San Diego sheds new light on how a type of heart valve disease, called aortic valve stenosis, progresses differently in males and females.

Taking a close look at our genetic blueprint reveals a surprising evolutionary drama that is unfolding right inside our cells ...
