By Scott Morrison, UC Berkeley Haas When UC Berkeley biochemist Jennifer Doudna first began studying how bacteria fight virus infections, she had no idea it would result in one of the most important scientific breakthroughs of the century. Her curiosity-driven research on an obscure bacterial immune system called CRISPR eventually led to a revolutionary gene-editing tool—and earned her the 2020 Nobel Prize in Chemistry.

U.S. Census data shows no systematic age differences between men and women in the workforce over the past decade. And globally, women on average live about five years longer than men.
