Heliyon Journal Confronts Extensive Retraction Surge Following Rigorous Internal Review
Heliyon, the open-access mega-journal from Elsevier's Cell Press, has undertaken a significant cleanup of its publication record. The journal, launched in 2016, published more than 11,000 papers in 2023 and over 17,000 in 2024. Retraction activity remained low in those years, with around two dozen retractions annually. In 2025 the picture changed dramatically. The journal published 3,168 articles while retracting 392 others. Early 2026 data show continued elevated retraction activity, with 37 papers retracted and 144 published in the first month alone. Total retractions have reached several hundred, prompting widespread discussion across academic communities about research integrity and mega-journal practices.
Background on the Journal and Triggering Events
Heliyon operates as a broad-scope mega-journal accepting submissions across scientific disciplines. It charges an article processing fee of approximately $2,270. The journal experienced rapid growth in submissions and output in recent years. In September 2024 Clarivate paused new content indexing for Heliyon in Web of Science, citing quality concerns. This action prompted Elsevier to launch a comprehensive internal audit covering all papers published since the journal's founding. The audit examined issues including citation manipulation, compromised peer review processes, authorship irregularities, and the presence of tortured phrases often associated with paper mills.
Retraction notices have cited reference problems, citation stacking, suspicious author affiliations, unexpected changes in authorship, and questions around ethical approvals. These factors collectively contributed to the decision to retract hundreds of articles. The journal has since reduced its publication volume substantially while prioritizing quality control measures.
Scale and Nature of the Retractions
The 2025 retraction total of 392 represents a sharp increase from the previous year's 26 retractions. Combined figures through early 2026 indicate more than 500 papers affected in total. Retraction Watch documented the surge in detail, noting that the journal's output dropped from peaks above 17,000 articles annually to just over 3,000 in 2025. This contraction reflects deliberate editorial tightening rather than a simple decline in submissions.
Many retracted papers originated from regions with high submission volumes to mega-journals. Concerns included coordinated citation practices and questionable research practices that evaded earlier detection. The audit process continues, suggesting additional retractions may follow as reviews progress.
Implications for Researchers and Academic Careers
Authors of retracted papers face immediate professional consequences. Retractions can affect tenure decisions, grant applications, and future publication opportunities. Early-career researchers and those in competitive fields feel the impact most acutely. Institutions increasingly scrutinize publication records during hiring and promotion processes, making integrity a central consideration.
PhD candidates and postdoctoral researchers who published in Heliyon must now evaluate how these retractions influence their CVs and career trajectories. Many are seeking guidance on correcting the record or shifting focus to journals with stronger integrity safeguards. University administrators are updating policies on acceptable publication venues and requiring additional verification steps for grant proposals.

Broader Effects on Scholarly Publishing Standards
The Heliyon case highlights systemic challenges facing mega-journals that prioritize volume. Rapid growth in submissions can strain peer review systems, creating opportunities for misconduct. Other mega-journals have faced similar scrutiny, leading to industry-wide conversations about sustainable publishing models.
Publishers are investing in advanced detection tools for image manipulation, text reuse, and citation anomalies. Editorial boards are expanding training for reviewers and implementing stricter authorship verification. These changes aim to restore confidence in the peer-reviewed literature while maintaining open access options for authors worldwide.
Perspectives from Stakeholders Across Academia
Faculty members express concern that legitimate research may be caught in the broader cleanup. Some note that citation errors or minor methodological issues should not automatically trigger retraction when core findings remain sound. Others argue that any compromise in the review process undermines the entire publication.
University leaders emphasize the need for proactive education on research ethics. Workshops on responsible authorship and citation practices are becoming standard offerings at many institutions. Funding agencies are also signaling greater attention to publication integrity when evaluating proposals.
Challenges in Maintaining Research Integrity at Scale
Mega-journals handle thousands of submissions monthly, making comprehensive vetting difficult. Paper mills exploit this scale by producing formulaic manuscripts with fabricated data or plagiarized content. Citation cartels artificially inflate impact metrics, distorting perceptions of journal quality.
Addressing these issues requires coordinated action across publishers, institutions, and indexing services. Shared databases of known problematic authors and reviewers are under development. Machine learning tools now assist in flagging suspicious patterns before publication. These technological advances complement traditional editorial oversight.
Future Outlook for Mega-Journals and Open Access
Heliyon's experience may influence how other mega-journals operate. Reduced output combined with heightened scrutiny could become the new norm. Authors may shift toward society journals or more selective open access platforms with established reputations.
The long-term effect on the open access movement remains uncertain. While retractions damage trust, they also demonstrate commitment to correction. Transparent retraction policies and clear communication help maintain credibility. Continued investment in integrity infrastructure will determine whether mega-journals can sustain their role in scholarly communication.
Actionable Steps for Academics and Institutions
Researchers should verify journal policies before submission and maintain detailed records of all research processes. Institutions can strengthen internal review committees and provide resources for ethical publishing. Collaboration with organizations focused on research integrity offers additional support.
Early-career scholars benefit from mentorship on navigating publication landscapes. Understanding retraction trends helps avoid high-risk venues. Regular engagement with professional development on research ethics prepares academics for evolving standards.
Conclusion and Path Forward
The retraction wave at Heliyon underscores the importance of vigilance in scholarly publishing. While the immediate impact includes disrupted careers and institutional reviews, the episode also drives positive reforms. Stronger safeguards, better detection tools, and renewed emphasis on integrity benefit the entire research community. Academics, administrators, and publishers must work together to uphold the standards that underpin scientific progress.
