Writing a Cover Letter for Science (AAAS): What the In-House Editors Actually Screen For

Science has a longer checklist of required cover letter elements than most journals. Miss any of these and you'll either get a request to resubmit with the missing information or, worse, you'll signal that you didn't read the submission guidelines.

1. Title and main point statement. State the title of your paper and, in one or two sentences, what the paper shows. Not what it "investigates" or "explores." What it demonstrates.

2. Related manuscripts elsewhere. If you have related manuscripts submitted, in review, or in press at other journals, disclose them. Science takes this seriously.

3. Pre-submission discussion references. If you contacted a Science editor before submitting, name them and reference the conversation. This is valuable real estate in your letter. Use it.

4. Names of colleagues who saw the paper. This is the requirement that surprises people. Science explicitly asks you to list colleagues who reviewed or saw a draft of your manuscript before submission. It's not optional. It's not a suggestion. List them.

5. Dual submission declaration. Confirm the paper isn't simultaneously submitted elsewhere.

6. Ethics statements. If your work involves human subjects or animal care, include the relevant ethics approval information.

7. Data availability statement. State where the data and materials underlying the paper can be accessed.

That's seven distinct elements. Most cover letters for other journals need three or four. If you're recycling a cover letter from a Nature or Cell submission, you're almost certainly missing something.

The best Science cover letters follow a pattern. Not because editors want formulaic writing, but because the pattern ensures you hit every requirement while still making a strong scientific case.

Opening paragraph: The finding and why it matters. Don't start with background or a ceremonial "we are pleased to submit" sentence. Start with what you found and why it changes something. The editors already know the field background.

Second paragraph: Broader significance. Science publishes for a readership that spans every discipline. Your finding about protein folding dynamics needs to matter to someone outside structural biology. Your climate model results need to connect to policy or ecology or economics. Make the cross-disciplinary case in two to three sentences. Be specific about which other fields benefit.

Third paragraph: Required disclosures. This is where you put the elements from the checklist above: related manuscripts, pre-submission discussions, colleague names, dual submission declaration, and ethics statements. Don't scatter these across the letter. Group them so the editor can verify compliance quickly.

Closing paragraph: Data availability and contact. State your data availability commitment and provide contact information for the corresponding author.

Weak: "We are pleased to submit our manuscript entitled 'Novel Insights into the Role of X in Y' for your consideration. In this study, we investigated the relationship between X and Y using a combination of experimental and computational approaches. Our results provide new understanding of this important biological process."

Why it fails: No specific finding. No claim. "Novel insights" and "new understanding" are empty phrases. The editor still doesn't know what you discovered. And "we are pleased to submit" wastes the most valuable sentence in the entire letter.

Strong: "We submit 'Direct Evidence that X Drives Y Through Mechanism Z' for consideration in Science. We show that X activates pathway Z in human tissue, resolving a two-decade question about whether the X-Y association is causal or correlational. This finding reframes therapeutic strategies for [disease] and introduces a target validated across three independent patient cohorts."

Why it works: Specific finding in the first sentence. A claim, not a hedge. The gap is named and dated. Clinical and therapeutic relevance is stated, connecting the work to medicine and drug development beyond the basic science.

We show that the specific finding resolves the named cross-disciplinary question, with the decisive evidence supporting the claim and the important boundary defining where it should not travel.

Any preprint is disclosed with its link and overlap, as is each related manuscript. Do not write “urgency and significance” as a substitute for the finding; use those ideas only when the evidence itself establishes why another field needs the result.

These defects follow from the current author instructions and the job of an editorial cover letter. They are checks an author can perform directly; they are not estimates of private Science outcomes.

Forgetting the colleague list. The current Science author guidance asks authors to identify colleagues who reviewed a draft before submission. Confirm the live wording and include the requested disclosure accurately.

Leaving the colleague list out creates a compliance gap. Fix it directly rather than guessing how often other authors make the same mistake.

Burying the finding under literature background. According to Science's author guidance, the cover letter should open with what the manuscript demonstrates, not with context about the field. Science employs more than 20 in-house PhD editors who handle every desk decision. These are not academic peers reviewing on weekends; they are full-time professionals who read hundreds of cover letters per week.

A cover letter that spends the first paragraph on "the role of X remains poorly understood" before stating the advance wastes the most important sentence the editor reads. Open with the result and its consequence, then supply only the context needed to understand it.

Omitting the data availability statement. Per Science's author guidelines, data must be deposited in public repositories with accession numbers, and analysis code must be publicly available. Science has increased its emphasis on open data and reproducibility significantly. A cover letter that does not state where data lives and confirm code availability looks incomplete before the science is even evaluated. According to Science's stated reproducibility commitments, this information is required in the cover letter as well as in the manuscript.

Writing a cover letter that treats Science and Nature as interchangeable. Science employs in-house editors with PhDs in specific fields, not academic editors rotating through the role. This means Science editors are generalists with deep training who are not necessarily in your discipline. Per Science's editorial model, the broader significance argument must be accessible to an editor who is highly trained but not a domain specialist.

A cover letter that relies on field-specific shorthand or assumes the editor knows why the gap matters will not land the same way it would with a disciplinary colleague. Translate the consequence without diluting the science.

Not referencing a pre-submission discussion when one occurred. Science accepts pre-submission inquiries, and if an editor responded positively, including a reference to that conversation in the cover letter changes how the submission is handled. Per Science's submission process, naming the editor and date signals that someone on the editorial team has already flagged the paper. A cover letter that omits this when a positive pre-submission conversation occurred leaves the most valuable piece of submission context unused.

A Science cover letter framing check is the fastest way to verify that your framing meets the editorial bar before submission.

A Science cover letter has to survive a rapid editorial read without becoming vague. Write the same contribution at three levels and check that each version points to the same evidence.

Now trace the strongest verb in the one-sentence version to the first two figures. If the evidence supports association rather than causation, prediction rather than explanation, or one context rather than a general rule, change the verb before submission. The cover letter should clarify the manuscript's reach, not enlarge it.

Before sending the letter, underline every result verb and connect it to a figure, table, or prespecified analysis. Then label the connection direct, supported with a boundary, or aspirational. Keep direct statements, qualify bounded ones, and remove aspirational ones.

This trace improves the letter without changing its job into a second abstract.

Before sending the letter, write its central significance claim in one sentence. Then compare that sentence with the title, abstract conclusion, first figure, discussion boundary, and disclosure record. The wording need not be identical, but the scientific reach must be. If the letter promises a cross-field consequence that appears only in the discussion, narrow the letter or strengthen the manuscript. If the first figure shows a narrow method result while the letter leads with a broad discovery, the editorial case is not yet stable.

Use a second pass for disclosure continuity. Related manuscripts, preprints, prior editorial contact, shared datasets, and overlapping figures should be described consistently wherever the submission asks for them. This check improves the letter because it joins editorial significance and submission trust instead of treating them as separate tasks.
