When a curious mind is given resources and opportunities to learn, research, test, teach, and invent, the possibilities are limitless. A woman builds solar lanterns that bring light to her Guatemalan town. Girls code a drone controlled by SMS messaging that will dispense medicine in rural areas. A woman pharmaceutical chemist wins the Nobel Prize for research on anti-malarial compounds that improve the health of millions. Women and girls in STEM are creators, entrepreneurs, innovators and leaders. They’re tackling some of the most pressing global challenges head-on, but, across the field, their participation remains relatively low.
