Scoop Watch: what does a close paper change about your project?

You plan to study the origin of gas in debris discs. A new paper asks a similar question through dust dynamics. An older paper models how primordial gas survives. Which is useful background, and which part of your project needs a sharper explanation?

Scoop Watch, available with Premium, compares papers with your project's question, method, data and expected results. This walkthrough follows an actual 28 October 2026 demonstration: an initial search, a more precise project description, a CC BY full-text comparison and a saved reading task. The project is fictional and contains no private data.

Describe a contribution, not just a topic

Open Scoop Watch. Give the project a title and at least 300 characters explaining what it will do. Our initial description combined a gas-evolution model with spatially resolved observations to distinguish gas-production mechanisms. It named no specific targets or new findings.

The initial project description states the question, approach and intended contribution, explicitly identifying the project as a public demonstration.

Include	A useful question to answer
Question	Which competing explanations will you distinguish?
Method	What will you model, measure or compare?
Data	Which systems, observations or datasets will you use?
Expected result	What would this work add, without presenting a plan as a finding?

You can also start from a draft PDF. The option to retain its text concerns later full-text comparisons. This demonstration used a written description only.

Set references, teams and a manageable alert frequency

The options let you exclude your own work through coauthor names, follow particular authors and supply key references. New papers by followed authors are read even if their similarity is low; papers citing several key references can also enter the comparison.

The screenshot shows an unsaved example: Wataru Ooyama as a followed author, 2608.22781 as a known reference, and immediate emails for strong overlaps with partial overlaps grouped weekly. These option trials did not change the existing project's email settings.

The optional team, reference and email settings can be specified independently. This form is a configuration example, not a newly activated subscription.

Separate new announcements from prior work

“New papers” follows announcements. “Already published” searches the previous three years across arXiv, journals and OpenReview. The first check and prior-work results appear on the page; they are not evidence of an email alert received.

The new-paper list includes Unbound grains in gaseous debris discs. Its partial overlap concerns the shared gas-origin question, while its dust-halo diagnostic differs from the initially proposed gas-distribution comparison.

A recent paper shares the project's question through a different approach. The brief explains both the connection and the remaining differences.

After retrying an interrupted search, the initial English example found 62 close papers, with the closest read by AI. The list can include preprint and journal versions of the same contribution: check identifiers before counting independent studies.

The completed initial search reports 62 close papers. The displayed journal version of the dust-dynamics paper belongs to prior work, distinct from the new-announcement list.

The first assessment uses abstracts. “All”, “Strong overlaps” and “Partial overlaps” filter the displayed matches. A search result count measures neither completeness nor the novelty of your project.

Refine the project when the first description is too broad

A vague description cannot establish whether papers use your intended data or method. We edited the demonstration to specify one-dimensional gas evolution, thermochemical calculations, CO and neutral-carbon radial profiles, HCO+ strengths, and matched beam and sensitivity treatment. It still makes no claim of new measurements or established findings.

“Edit the project” adds concrete methods and observables to the fictional plan. Saving retains existing matches and starts a new search for prior work.

The new pass reported 58 close papers and added further comparisons. Earlier matches remain in the project; their original briefs are not automatically rewritten to reflect every edit. The numbers from successive passes should not be added as a count of unique studies.

A partial overlap can still be essential reading

The refined search returned A Primordial Origin for the Gas-rich Debris Disks around Intermediate-mass Stars, by Nakatani et al., published in The Astrophysical Journal Letters in 2023, DOI 10.3847/2041-8213/ad0ed8, under CC BY 4.0.

Nakatani et al. (2023) is classified as a partial overlap: the gas-origin question is shared, while the modelling approach and proposed observations differ.

Read “In common” and “What stays yours” together. The latter suggests distinctions to verify; it does not certify originality. A partial overlap can deserve a citation and affect how you frame the project.

Read beyond the abstract before deciding what is new

Choose “Compare with the full text”. For this openly licensed paper, the completed comparison gives a question–method–data–results table and a more specific assessment. If full-text analysis is unavailable, use the abstract-level result with that limitation in mind.

The full-text comparison adds a useful qualification: the older paper already discusses some proposed modelling directions as future work, so those ingredients alone are a weak novelty claim.

The practical advice is to define a controlled comparison of origins on matched systems and quantify whether the observations can separate them. Treat the advice as a reading and planning aid: inspect the cited paper and relevant methods before adopting it.

The final rows and advice turn the overlap into concrete checks on observational distinguishability, assumptions and citations.

A useful follow-up is Mitani et al.'s thermochemical study, a CC BY 4.0 preprint submitted to arXiv on 24 August 2026. This is an additional reading example, separate from the Nakatani match above. Its source banner confirms full-text analysis; the displayed journal-submission comment is not an acceptance date.

The follow-up paper is clearly identified as a 2026 arXiv submission. Its licence and full-text source banner are visible.

Open “Figures and plots” to inspect the radial profiles and the illustrative synthetic CO map. The authors' text explains how that image was constructed. A synthetic image is a model prediction, not a new observation.

Save the paper with the question it changes

We marked the Nakatani paper as a “Real overlap” in the demonstration project. This records relevance without changing the partial-overlap label. “Not relevant” reduces the weight of similar papers; “Undo” removes your feedback.

The Nakatani result now says Marked relevant while keeping its Partial overlap classification. Relevance feedback and overlap category answer different questions.

We added it to a new private collection, set “To read”, and noted what to cite and what to test: matched-system comparisons, spatial profiles, sensitivity and degeneracies. The note and status persisted after reloading.

The saved reference carries a specific reading task about the project's distinguishing contribution, rather than a generic bookmark.

Continue with the Collections guide to organize several papers, or chat with one paper to investigate a precise claim. Scoop Watch supports reading, citation and a clearer research plan; its comparisons do not establish priority or prove that an idea was appropriated.
