We investigate the impact of new research opportunities on the long-standing under-representation of women in medical and academic leadership by assessing the impact of the emergence of COVID-19 as a new research topic in the life sciences on women's authorship. After collecting publication data from 2019 and 2020 on biomedical publications, where the position of first and last author is most important for future career development, we use the major Medical Subject Heading (MeSH) terms to identify the main research area of each publication and measure the relation of each paper to COVID-19. Using a Difference-in-Difference approach, we find that although the general female authorship trend is upwards, papers in areas related to COVID-19 are less likely to have a woman as first or last author compared to research areas not related to COVID-19. Conversely, new publication opportunities in the COVID-19 research field increase the proportion of women in middle, less-relevant, author positions. Stay-at-home mandates, journal importance, and access to new funds do not fully explain the drop in women's outcomes. The decline in female first authorship is related to the increase of teams in which both lead authors have no prior experience in the COVID-related research field. In addition, pre-existing publishing teams show reduced bias in female key authorship with respect to new teams specifically formed for COVID-related research. This suggests that opportunistic teams, transitioning into research areas with emerging interests, possess greater flexibility in choosing the primary and final authors, potentially reducing uncertainties associated with engaging in productions divergent from their past scientific experiences by excluding women scientists from key authorship positions.
