On February 11 the world celebrates International Day of Women and Girls in Science. This day, which recognizes the crucial role of women and girls in science and technology, was established in 2016 through a resolution of the United Nations General Assembly. Some of the most relevant points of this resolution, in my opinion, are the promotion of (1) full and equal participation for women and girls, both in their education, as well as their work environment and (2) full participation by women and girls in decision making in science.
