Why are biologists embracing preprints? A look at trends, scooping, and the benefits of preprints for early-career researchers

Much has been written about preprints over the last few years, about their place in open science and their increasing role in science communication. Behind many preprints there are early-career researchers seeking to share their work with their community. Why are early-career researchers embracing preprints?

Behind many preprints there are early-career researchers seeking to share their work with their community. Why are early-career researchers embracing preprints?

Preprints in biological sciences have grown in strength over the last few years, supported by the launch of new preprint servers, increased awareness among researchers, and policies by some funders that recognise preprints as valid research outputs. While funder policies about preprints vary, as shown by the Australian Research Council’s controversial decision to disqualify grant applicants who included references to preprints,1 the US National Institutes of Health, the European Research Council, and a number of other funders accept preprints.2 Preprints were initially used mostly in disciplines like neuroscience, bioinformatics, and genomics; however, many fields in experimental biology have progressively adopted preprints. The number of preprints in biochemistry and cell biology, for example, increased by 700% from 2016 to 2020 (figure 1).

Journals have also contributed to this trend. Most journals in the life sciences accept the submission of papers deposited as a preprint, some operate workflows to easily transfer papers from servers such as bioRxiv to the journal, and others will offer you, during the submission process, the option of depositing the paper at a preprint server at the same time. In a further innovation in editorial policies around preprints, the journal eLife now only reviews manuscripts that have been first posted as a preprint.3

As an early-career researcher, the first way to become involved with preprints is as a reader. Reading a preprint will allow you to stay up-to-date with the latest research without waiting until it appears in a journal several months or even a year later. This is critical when you are working on the same topic as other colleagues; the findings from the latest preprints could help you design experiments and plan new research lines. The other side of the coin is when a preprint reports similar findings as those you are working on, before you can wrap up your paper. This can also happen with journal publications, but unlike being “scooped” by a journal publication, preprints allow you to turn this dreaded moment into an opportunity. There are several examples of researchers who realised they were working in the same area after seeing a preprint, and they got in touch with each other to start a fruitful collaboration, often allowing them to also coordinate journal submission for their papers.4

Publishing preprints can be an incredible opportunity to start a new collaboration and receive constructive criticism. The fear of being scooped unevenly affects researchers in developing countries who may have access to fewer resources than well-funded laboratories. Strictly speaking, research published first in the form of preprints cannot be scooped, because the preprint provides a date-stamped permanent record of your work. In that sense, publishing a preprint puts you in a better position to discuss your work with the journal editors when it is completed. Journals are slowly incorporating scooping-protection policies that extend to the date of the preprint. Thus, what for some was a major concern about preprints is becoming their greatest strength: preprints can be used as a date-stamped flag to claim priority for a research result. This allows the fair use of preprints in collaborative research and open science. A personal experience could be useful to illustrate this case. While working on a prior project last year, my co-authors and I realised that another group had found a similar phenotype to the one that we were working on. We decided to collaborate to decipher this phenomenon, but when the time came to publish our findings, we realised that both stories were still significantly different in content and scope. However, we also knew that if we submitted the two papers and one of them was accepted by a journal before the other, the novelty of the second article could be affected. In light of this, we decided to wait until both manuscripts were ready to submit and, instead of following the conventional path of submitting both papers to the same journal as back-to-back papers, we submitted our preprints to bioRxiv on the same day. That way, we made clear that the papers did not seek to claim novelty over each other and allowed both papers to have completely independent editorial processes. Happily, the articles were published in different journals, without any question from the reviewers as to whom found the phenomenon first. This is a personal example, but there are many other ways in which you can take advantage of preprints. Do you want to share an unpublished result with a colleague but are afraid that the information could be stolen? Post a preprint. Do you have a manuscript that references your own work but is still under review? Publish a preprint and now you can cite it. Preprints speed up research in many ways, they promote open science, and they allow you to control when you share your work with the community.

The free and wide availability of preprints has also created new avenues for early-career researchers to participate in peer review and curation of research which were not open within the journal process. A number of initiatives are available to early-career researchers: preLights is a platform by the Company of Biologists which allows early-career researchers to publish highlights of preprints they find of interest;5 PREreview is an open-source platform where researchers can solicit and post reviews on preprints, and it also coordinates a mentoring programme aiming to empower early-career researchers to contribute peer reviews;6 Plantae, an initiative by the American Society of Plant Biologists, circulates a weekly summary of research highlights, including preprints, which is curated by early-career researchers.7 In addition, many journal clubs incorporate or are now focused on preprints, so there are plenty of opportunities to hone your reviewing skills while keeping abreast of the latest preprinted research findings.

Whether you use them to disseminate your work, to keep up with the latest developments in your field, or to contribute to review or curation initiatives, preprints have much to offer to early-career researchers. Wondering where to start? It’s simple: keep an eye on the latest preprints coming out in your area of research and start a conversation with your supervisor and collaborators about posting a preprint for your next paper. Chances are they have also been thinking about preprints!
