The lack of female representation in scientific communities is staggering; according to the U.S. Census Bureau statistics, only 7% of the STEM (science, tech, engineering, mathematics) community was made up of women in 1970. And while that number has risen in the last 4 decades (we're now at 26%), we're still at an embarrassing low rate. Besides the fact that this lack of women in an entire field could be hindering the work being done, millions of young girls are missing positive, intelligent role models. The scientists on this list are doing their part to inspire people everywhere in all kinds of ways. Let's take a closer look at what they've done and how they're helping bridge that gender gap.
