Many Voices, One Science

Feb 10, 2026
Supporting the International Day of Women and Girls in Science, IUPAC's Global Women’s Breakfast fosters a global network to break barriers to equality in science. Over the past seven years, nearly 2,500 GWB events have united participants from 100 countries.
This year, there are already more than 235 events in 49 countries registered ... and more are still coming
GWB2026 will take place on February 10, 2026 and the theme is: “Many Voices, One Science.”
