[Is science for everyone? bioethical challenges of current editorial practices].

As Drumond Rennie put it, ‘Science does not come alive until it is shared publicly’ (1998), emphasising that the rapid advancement of scientific research requires its efficient and rigorous dissemination both to encourage the development of new strategies and to avoid duplication of effort and resources. The current model of scientific and technological research is facing a significant challenge: the cost associated with publishing its results. It is now increasingly common for publishers to impose fees on the scientific community to publish their results, generating debate about the impact of this practice on the fairness of scientific dissemination. Requiring researchers to pay publication costs would limit or exclude research from countries with limited resources, creating significant barriers to the dissemination of knowledge. It has been estimated that costs in some cases are up to ten times higher than what is considered adequate to cover the actual costs of publication (Grossmann & Brembs, 2021). This mismatch raises questions about the justification for such fees and the benefits to funders, given that the funds are often public, or even come from researchers' own pockets. Moreover, this current model supports a highly lucrative publishing industry, valued at approximately $10 billion (Global $10B Scientific & Technical Publishing Industry Report, 2019-2023), and is possibly one of the main causes of the emergence of so-called Predatory Journals. These journals, sometimes described as fraudulent, appear to be legitimate journals, but in reality distort certain publication practices, with a purely profit-driven ultimate purpose (Elmore & Weston, 2020), representing an ethical violation by exploiting the need of researchers for financial gain without providing true scientific value. Given the current landscape, it is crucial to reflect on how these practices affect equity in the dissemination of scientific knowledge?, and how publishing power can limit the dissemination of research on specific pathologies in emerging countries, restricting the right of communities to access crucial information and develop effective public health policies?. Undoubtedly, equity of access to and distribution of scientific knowledge is a fundamental principle that must be strongly defended. Paying high costs for scientific and technological publication not only jeopardises equal opportunities for researchers from regions with fewer resources, but also affects fairness in the distribution of knowledge. This economic barrier can result in a systematic exclusion of relevant perspectives and data from emerging countries, deepening inequalities and limiting global progress in critical areas such as public health. Consequently, there is a need to re-examine the current publication model to ensure that science continues to advance in a way that is fair and accessible to all, and to ensure that information vital to public health and scientific progress is not restricted by economic barriers, but is based on principles of fairness and transparency. Indeed, the scientific community must work together to promote the dissemination of knowledge in a manner that is accessible, equitable and free from harmful practices.
