The number of articles in English increased more than fivefold between 1990 and 2023, rising from approximately 877,000 to nearly 5,000,000. It is the relative share of English that has declined as other scientific communities have gradually begun publishing more in their own languages.
English dominates scholarly publishing, but other languages are gaining ground

Top left: This view of the zebrafish ventricle reveals the emergence of future coronary vessels, made visible through two fluorescent lines that label endothelial cells as they form. Bottom left: Using different fluorescent markers, this image simultaneously shows nascent coronary vessels, cardiomyocytes, and proliferating cells, illustrating the synchronized growth of the vascular network and the cardiac muscle. Bottom right: This view highlights the parallel progression of the developing coronary vessels and the growing cardiac muscle tissue, each marked with a distinct fluorescent color that allows their coordinated maturation to be followed.
