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. Don't start with "Dear Editors, we are pleased to submit..." Start with what you found and why it changes something. The editors know the background. They have PhDs in your field or an adjacent one.

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.

Science accepts pre-submission inquiries, and using one before writing your full cover letter is a smart move. Contact the editorial office with a brief summary of your findings (a few paragraphs, not a full abstract). If an editor responds positively, that response becomes one of the strongest elements you can include in your cover letter.

"We discussed this work with Dr. [Name] on [Date], who indicated the topic would be of interest to Science" is a sentence that changes how your submission is handled. It tells the receiving editor that someone on the team has already flagged this paper. It won't guarantee acceptance, but it can prevent an uninformed desk rejection.

Your cover letter is a persuasion document, not a summary. It's worth getting feedback on it separately from the manuscript itself. Ask a colleague outside your subfield to read just the cover letter and tell you: can you explain what the paper found and why it matters?

If they can't, rewrite. An AI-powered manuscript review can also catch structural problems, missing required elements, and framing issues that are hard to see in your own writing. The point isn't to outsource the letter. It's to make sure the letter does what you think it does before it lands on an editor's desk.

Understanding what happens after your cover letter arrives helps you calibrate expectations.

If your paper survives the desk review stage, you've already beaten 75% of the field. The cover letter's job is to get you past that first gate. Everything after that depends on the science, the reviewers, and the editorial discussion.
