The Science Without Borders (SWB) Challenge is an international student art competition. The theme for this year’s challenge is “Microscopic Marine Life.” Students are asked to create artwork celebrating the vital role of tiny ocean organisms—like phytoplankton, zooplankton, bacteria, and protists—that sustain marine ecosystems, produce oxygen, recycle nutrients, and regulate Earth’s climate. The SWB Challenge is open to primary and secondary school students (aged 11-19 years) from all around the world. The winners will receive scholarships of up to US$500. The deadline is 02 March 2026.
