Showing all 37 problems.

Problem 1Publishers · Journals

Paper mills grow faster than real science

Evidence. Fraudulent papers are growing at a rate “far outpacing” legitimate science (Richardson et al. 2025, PNAS).

Solved means

A screen that flags paper-mill submissions before review, tested on retracted paper-mill papers against genuine ones, with its error rates published.

Submit a solution →

Problem 2Editors

Fake peer reviewers

Evidence. A major publisher retracted more than 100 papers from one cancer journal over faked reviews in 2017 (Retraction Watch).

Solved means

A check that confirms within minutes that a suggested reviewer is the real person behind the e-mail address.

Submit a solution →

Problem 3Authors · Universities

Hijacked and predatory journals fool authors

Evidence. The Hijacked Journal Checker passed 400 entries in Dec 2025 (Retraction Watch); an agreed definition of a predatory journal exists only since 2019 (Grudniewicz et al., Nature).

Solved means

An open check that spots a cloned journal site within days and tests any journal against the 2019 definition, explaining each verdict.

Submit a solution →

Problem 6Journals · Editors

Disguised plagiarism (“tortured phrases”)

Evidence. Rewriting tools turn “artificial intelligence” into “counterfeit consciousness”; such phrases mark machine-rewritten text in published papers (Cabanac et al. 2021).

Solved means

Detection of machine-paraphrased text in any language, with its error rates published.

Submit a solution →

Problem 7Journals · Universities

Undisclosed AI-written text

Evidence. LLM use in computer-science papers reached an estimated 17.5% by Feb 2024; 950,965 papers studied (Liang et al. 2024).

Solved means

A fair check of AI use whose rate of wrongly flagged honest papers is measured and published.

Submit a solution →

Problem 8Authors · Publishers

Retracted papers keep being cited

Evidence. In biomedicine, only 5.4% of 13,252 citations made after a retraction mention it (Hsiao and Schneider, QSS).

Solved means

A way to mark, in the citing papers’ own records, that a cited work was retracted, and to tell their authors.

Submit a solution →

Problem 9Publishers · Libraries

Journals vanish from the web

Evidence. 174 open-access journals vanished from the web between 2000 and 2019 (Laakso et al. 2021, JASIST).

Solved means

Low-cost, automatic preservation that keeps a small journal’s articles readable after the journal closes.

Submit a solution →

Problem 10Authors · Journals

Links in reference lists die

Evidence. One in five science articles suffers from reference rot; seven in ten of those that cite web pages (Klein et al. 2014, PLOS ONE).

Solved means

Every web link in a reference list kept readable years later, done automatically at publication.

Submit a solution →

Problem 11Authors · Indexes

Preprints lose their journal version

Evidence. For 132,339 bioRxiv and medRxiv preprints, the links to their journal articles are incomplete in the servers’ metadata and in Crossref (Langnickel et al. 2022, JMIR).

Solved means

An accurate matcher that links each preprint and its published version, both ways, in the registries.

Submit a solution →

Problem 12Researchers · Industry R&D

Results that cannot be reproduced

Evidence. More than 70% of researchers have tried and failed to reproduce another scientist’s experiments (Baker 2016, Nature); one biotechnology company confirmed the findings of only 6 of 53 papers (Begley and Ellis 2012, Nature).

Solved means

A low-cost check, before publication, that a paper’s main result can be rerun from its shared data and code.

Submit a solution →

Problem 14Researchers · Universities

English as a barrier

Evidence. Non-native English speakers spend more effort reading, writing and presenting in English; 908 researchers surveyed (Amano et al. 2023, PLOS Biology).

Solved means

Affordable, accurate publishing in the author’s own language, with every language version linked as one work.

Submit a solution →

Problem 15Authors · Universities

Fees shut out low-income authors

Evidence. One publisher’s open-access “mirror” journals had no articles by authors in low-income countries (Smith et al. 2021, QSS).

Solved means

A model that lets authors in low-income countries publish open access at no cost and keeps the journal funded.

Submit a solution →

Problem 17Authors · Reviewers · Libraries · Indexes

Hallucinated references entering the record

Evidence. In short literature reviews written by an AI chatbot, 55% of the references from one version and 18% from its newer version were fabricated (Walters and Wilder 2023, Scientific Reports).

Solved means

A public check that flags ≥95% of nonexistent references in a blind test set of 1,000 submitted reference lists, with <2% false flags, used at ingestion by at least one major index.

Submit a solution →

Problem 18Researchers · Indexes

Retraction status disagrees between databases

Evidence. A considerable number of retracted papers and retraction notices in PubMed are not labelled as such in Web of Science, or cannot be told apart from corrections there (Schmidt 2017, JASIST).

Solved means

For a random sample of 1,000 retracted items, PubMed, Crossref, Scopus, WoS and OpenAlex show the same status within 30 days of the notice in ≥98% of cases.

Submit a solution →

Problem 19Researchers · Public & policy

Stealth (unannounced) corrections to the Version of Record

Evidence. Changes made to published papers without any correction notice, “stealth corrections”, were found and documented (Aquarius et al. 2025, Learned Publishing).

Solved means

Any change to a published VoR’s text/figures is detectable by a third party (hash/diff) and linked to a notice, demonstrated on ≥3 publishers.

Submit a solution →

Problem 20Editors · Authors

AI-written peer review reports

Evidence. An estimated 6.5% to 16.9% of the peer-review text submitted to four AI conferences could have been substantially modified by LLMs (Liang et al. 2024, arXiv 2403.07183).

Solved means

A disclosure + verification method that editors can apply per review, validated with <5% false accusation rate on a blind set.

Submit a solution →

Problem 21Editors · Industry R&D

Hidden prompt injection in manuscripts to steer AI reviewers

Evidence. Instructions hidden in preprints, in white text or small font, told AI tools to give the paper a positive peer review (Gibney 2025, Nature news).

Solved means

A screening step that detects ≥95% of hidden instructions (white text, tiny font, metadata) in a red-team test set, adopted by ≥1 major submission system.

Submit a solution →

Problem 22Journals · Repositories · Reviewers

LLM-fabricated research datasets

Evidence. A large language model’s data-analysis tool was used to create a fake data set for medical research (Taloni et al. 2023, JAMA Ophthalmology).

Solved means

A method that distinguishes synthetic from real tabular clinical data with AUC ≥0.95 on unseen data, or a provenance chain attached to deposited data.

Submit a solution →

Problem 24Repositories

AI crawlers overwhelming open repositories

Evidence. Over 90% of the 66 repositories that answered a 2025 survey said they were encountering aggressive bots (COAR survey 2025).

Solved means

A shared bulk-access mechanism reducing bot load on participating repositories by ≥50% without reducing human access, measured over 6 months.

Submit a solution →

Problem 25Repositories · Researchers

Flood of AI-generated review/position papers on preprint servers

Evidence. In October 2025, arXiv’s computer-science category began to require that review articles and position papers have passed peer review at a journal or conference, because of an unmanageable influx of them (arXiv blog, 31 Oct 2025).

Solved means

A triage method that cuts moderator time per submission by ≥50% while keeping wrongly rejected genuine papers <1%.

Submit a solution →

Problem 26Researchers · Funders

Research software rarely cited properly

Evidence. There is little support across the scholarly ecosystem for acknowledging and citing software (Smith et al. 2016, PeerJ Computer Science); in a random sample of 90 biology papers, only 31% to 43% of mentions of software were formal citations (Howison and Bullard 2015, JASIST).

Solved means

In a sample of 1,000 new papers, ≥70% of used software is cited with a resolvable PID including version.

Submit a solution →

Problem 27Researchers · Repositories

Dataset citations not counted

Evidence. 88.1% of the records in a citation index of research data had received no citation, and citing data was rare in most fields (Robinson-García et al. 2015, JASIST).

Solved means

Data citations captured by open infrastructure for ≥80% of data reuse in a verified sample.

Submit a solution →

Problem 28Authors

Name disambiguation fails for East Asian / non-Latin names

Evidence. Telling authors apart by their initials distorts measures of coauthorship networks, and Asian names accounted for most of the misidentifications (Kim and Diesner 2015, JASIST).

Solved means

Disambiguation achieving F1 ≥0.95 on a benchmark of common Chinese/Korean/Indian names.

Submit a solution →

Problem 29Researchers

Indexing bias against non-English and regional journals

Evidence. The coverage of Web of Science and Scopus favours the natural sciences, engineering and biomedical research, and over-represents journals in English (Mongeon and Paul-Hus 2015, Scientometrics).

Solved means

An evaluation-grade index whose coverage per country is within 10% of a ground-truth national register in ≥10 countries.

Submit a solution →

Problem 30Researchers · Public & policy

Negative results disappearing

Evidence. Negative results were found to be disappearing from most disciplines and countries (Fanelli 2011, Scientometrics).

Solved means

Open registry where null results get DOIs and are indexed; measurable increase in published null results in ≥3 fields.

Submit a solution →

Problem 31Reviewers · Editors

Peer review reports lost and uncredited

Evidence. Open peer review, where reviewers’ names or reports are published, was among the last parts of open science to be widely taken up: 617 journals were found practising it by 2019, in widely varying ways (Wolfram et al. 2020, Scientometrics).

Solved means

Peer reviews for ≥20% of articles in a field registered with PIDs linked to the article.

Submit a solution →

Problem 32Authors · Universities · Funders

Coercive citation by editors/reviewers

Evidence. Many journal editors appear to pressure authors into citing the editors’ own journals (Wilhite and Fong 2012, Science).

Solved means

An auditable method detecting coercive citation requests in confidential review systems with verified precision.

Submit a solution →

Problem 33Public & policy

Clinical trial results unreported and unlinked to papers

Evidence. Of 7,274 trials on the EU Clinical Trials Register whose results were due, only about half had reported them (Goldacre et al. 2018, BMJ).

Solved means

Trial registry IDs present in ≥90% of trial publications’ metadata and linked both ways.

Submit a solution →

Problem 35Journals · Researchers

Fully AI-generated papers with no accountable author

Evidence. An AI system wrote complete research papers end to end, from the idea and the experiments to the write-up, and then ran a simulated review of them (Lu et al. 2024, arXiv 2408.06292).

Solved means

A verification method (e.g. lab-notebook/provenance attestation) that a journal can use to confirm human accountability for ≥95% of a blind set mixing human and AI-agent papers.

Submit a solution →

Problem 36Authors · Publishers

No attribution or consent when papers train AI models

Evidence. Research papers have almost certainly been used to train AI models, and publishers have sold access to them in deals made without consulting the authors (Gibney 2024, Nature news).

Solved means

A method that, for a given paper and model, establishes training inclusion with verified accuracy, plus a credit record linked to the paper’s DOI.

Submit a solution →

Problem 37Journals · Editors

AI-generated scientific images with no capture provenance

Evidence. Images made by AI image generators are very difficult to identify, whether by eye or with image-forensic and detection tools (Gu et al. 2022, Patterns).

Solved means

Raw images in ≥1 journal carry a verifiable chain from instrument capture to figure, or a detector holds AUC ≥0.95 on images from unseen generators.

Submit a solution →

The sources are linked as evidence only.

The rules

Free to enter, judged on merit and never by chance.

  1. Who can enter. Anyone aged 18 or over, alone or as a team, from any country where the prize can lawfully be paid. Smart Scholars staff, the judges and their families cannot win.
  2. No fee, no purchase. Entry is free. Nobody has to buy or use a Smart Scholars service to enter or to win.
  3. What to send. The problem number, how the solution works, evidence that it works on real or public data, and a link to the working code or method where there is one. One entry per problem per person or team.
  4. What counts as solved. The entry meets the “Solved means” line of its problem, and the judges can check it themselves. An idea or a plan alone does not win.
  5. Judging. Scored out of 100: solves the stated problem (40), proof that it works (25), usable by journals of every size (20), originality (15). The judges’ decision is final; every winner’s score and the reasons are published. Solves the stated problem40Proof that it works25Usable by journals of every size20Originality15
  6. No winner below the bar. If no entry meets the bar, no prize is paid for that problem and it stays open for the next round.
  7. Deadline. Round 1 closes 31 May 2027 at 23:59 IST; winners are named by 30 June 2027. Entries sent from the day this page was published count in round 1, which opens on 1 December 2026.
  8. The prize. US$1,000 for the highest-scoring solution of the round, plus free Smart Scholars services: one year for one journal, for the highest-scoring entry that solves each problem. For a winner with no journal of their own, the year can go to a journal they choose: one they edit, review for or name. The money is paid within 30 days of the winner’s identity and payment details being confirmed: bank transfer in India; an international bank transfer or an online payment service abroad.
  9. Taxes. Any tax the law requires us to deduct is deducted before payment, with a certificate. Winners pay any tax due in their own country.
  10. Ownership. Entrants keep every right to their work. Entering allows Smart Scholars to publish the entry’s title, a short summary and the winner’s name. Any use of a winning solution in our services is agreed with the winner separately.
  11. Honest work. Entries must be the entrants’ own. AI tools may be used if the entry says how. Copied or fabricated results are disqualified, including after the prize is paid.
  12. Privacy. Entrants’ details are used only to run the prize and are never sold or shared.
  13. Changes. Errors in the rules may be corrected before a round opens. Once it is open, a change applies only if it helps entrants. Void where the entrant’s own law forbids it.
  14. Live check. The judges may ask an entrant to show the work live and to answer questions about it. An entrant who cannot is not considered.
  15. Same answers. If several entries are substantially the same, for example the same answer from an AI tool, none of them can win for that problem.
