First and last authors more likely to be men in leading science journals

A recent Nature Index analysis, published online on June 2, 2026, reveals that men continue to disproportionately hold first and last authorship positions in leading science journals, despite a significant rise in women's participation in scientific fields over the past decade. The analysis, which examined authorship trends over ten years, found that gender gaps in these crucial author roles have "barely shifted." First authorship typically signifies the primary researcher who conducted the bulk of the work, while last authorship often indicates the senior researcher or principal investigator who led the project and secured funding. These positions are widely recognized as indicators of significant scientific contribution and career advancement.

The findings suggest that systemic issues may be hindering women's progression to leadership roles within scientific research. While more women are entering scientific disciplines, their representation in positions that confer the most credit and recognition appears to be stagnating. This disparity has implications for career progression, grant funding, and the overall recognition of women's contributions to science. The persistence of these gender gaps could also influence the perception of science as an inclusive field, potentially impacting future recruitment and retention of female talent.

This analysis builds upon previous research highlighting gender disparities in academia. While the overall number of women in science has increased, the "leaky pipeline" phenomenon, where women drop out of scientific careers at higher rates than men at various stages, remains a concern. The Nature Index's focus on authorship provides a specific metric to track progress, or lack thereof, in achieving gender equity at the highest levels of scientific output. The study's methodology involved analyzing authorship data from a broad range of high-impact scientific journals, providing a robust dataset for its conclusions. The implications of these findings are significant for scientific institutions, funding bodies, and policymakers aiming to foster a more equitable research environment.
