Manuscript selection

Science is a weekly, peer-reviewed journal that publishes significant original scientific research, plus reviews and analyses of current research and science policy. We seek to publish papers that are influential in their fields or across fields and that will substantially advance scientific understanding. Selected papers should present novel and broadly important data, syntheses, or concepts. We welcome submissions from all fields of science and from any source.

Manuscripts should be submitted at our manuscript submission and information portal The status of submitted manuscripts can also be tracked at this portal.

Authors should familiarize themselves with the overall editorial policies for the Science Journals before submitting their paper. These policies spell out the rights and responsibilities that authors agree to when submitting and publishing their papers. Access this information here.

Peer-Reviewed Research Manuscripts

Research Articles (up to ~4500 words, including references, notes and captions–corresponds to ~5 printed pages in the journal) are expected to present a major advance. Research Articles include an abstract, an introduction, up to six figures or tables, sections with brief subheadings, and about 40 references. Materials and Methods should be included in supplementary materials, which should also include information needed to support the paper's conclusions.

Science also accepts a few Research Articles for online presentation. These are expected to present significant research results that cannot be fully presented in the print format and merit the extra length and attention provided by this presentation. The cover letter should indicate why the additional length is merited. These can be up to 8000 words and include methods, additional figures and potentially videos, as part of the main article. Additional supplementary materials which include information needed to support the paper's conclusions, are allowed. The full text will be included in all digital versions of Science, and a structured abstract will be included in the print version. A pdf of the full article can be downloaded.

Reports (up to ~2500 words including references, notes and captions–corresponds to ~3 printed pages in the journal) present important new research results of broad significance. Reports should include an abstract, an introductory paragraph, up to four figures or tables, and about 30 references. Materials and Methods should be included in supplementary materials, which should also include information needed to support the paper's conclusions.

Reviews All Reviews, except reviews in Special Issues, are now published online, where additional length, references, and enhanced media, are possible. The full text will be included in all digital versions of Science, and an enhanced abstract consisting of 550-600 words divided into 3 sections headed Background, Advances, and Outlook will be included in the print version. Reviews can be up to 6000 words and include up to 100 references, and 4-6 figures or tables. Reviews do not contain supplementary material. They should describe and synthesize recent developments of interdisciplinary significance and highlight future directions. They include an abstract, an introduction that outlines the main themes, brief subheadings, and an outline of important unresolved questions. Unsolicited offers of Reviews are considered. Proposals in the form of an enhanced abstract, one figure, and a list of 5-10 of the most important recent citations should be emailed to 


Science's Insights section presents analysis by scientists and other experts on issues of interest to Science readers. With the exception of Letters, eLetters, and Technical Comments, most items in this section are commissioned by the editors, but unsolicited contributions are welcome. Perspectives and Policy Forums should include an abstract. Commentary material may be peer reviewed at the Editors' discretion.

  • Perspectives (up to 1000 words plus 1 figure) highlight recent exciting research, but do not primarily discuss the author's own work. They may provide context for the findings within a field or explain potential interdisciplinary importance. Perspectives that comment on papers in Science should add a dimension to the research and not merely be a summary of the experiments described in the paper. Although many Perspectives that comment on research published in Science are solicited, we welcome inquiries regarding new advances and fresh insights. As these are meant to express a personal viewpoint, with rare exceptions, Perspectives should have no more than two authors.
  • Books or Media Reviews (up to 800 words) feature commentary on new books, films, exhibitions, performances, mobile applications, podcasts, and other media that are likely to be of broad interest to our readership. Please contact the Book Review Editor before you begin preparing your book or media review, indicating why you believe the work would be of interest to Science readers, and why you are well-positioned to write the review.
  • Policy Forums (1000 to 2000 words, 1-2 figures, and up to 15 references) presents issues related to the intersections between science and society that have policy implications.
  • Letters (up to 300 words) discuss material published in Science in the last 3 months or issues of general interest. Letters should be submitted through our Manuscript Submission and Information Portal ( Letters may be reviewed. The author of a paper in question is usually given an opportunity to reply. Letter submissions are acknowledged upon receipt by Science’s automatic system, but letter writers are not always consulted before publication. Letters are subject to editing for clarity and space. Letters rejected for print publication may be posted as eLetters.
  • eLetters are brief online comments that can be submitted in response to papers or news stories published in Science. eLetters are submitted on the Science website, evaluated, and posted with the article if accepted. Authors are identified and must agree to our terms and conditions ( 
  • Technical Comments (up to 1000 words, 2 figures or tables, 15 references, and no Supplementary Materials), are published online and critique the core conclusions and/or methodology of research published in Science within the previous 3 months. The abstract (60 words or less) will be included in the Letters section of the print edition. Technical Comments should not present new data or other previously unpublished work nor be based on new findings/concepts that would not have been accessible to the authors when the paper was written. Pertinent comments on non-technical aspects of a paper should be submitted as eLetters. Authors of Technical Comments should contact the authors of the paper before submitting their manuscript, and should submit to Science the relevant correspondence. Technical Comments that are accepted will be posted online along with a formal reply from the authors of the original paper. 

Preparing your manuscript

We accept submissions only online at Preparing a manuscript that follows our guidelines concerning length, style and acceptable file formats will facilitate the evaluation process.

See Guidelines for Preparing a New Manuscript. Revised manuscripts for the most part follow the same style guidelines, however there are some differences, particularly in figure preparation. See Guidelines for Preparing a Revised Manuscript.

Manuscript selection

Science is committed to thorough and efficient evaluation of submitted manuscripts. Papers are assigned to a staff editor who has knowledge of the manuscript’s field-of-study. Most submitted papers are rated for suitability by members of Science’s Board of Reviewing Editors. The editors at Science consider this advice in selecting papers for in-depth review. Authors of papers that are not selected for review are notified promptly, within about 2 weeks.

Research papers that are selected for in-depth review are evaluated by at least two outside reviewers, who are contacted before being sent a paper and asked to return comments within 2 weeks in most cases. Once all reviews are in, we initiate a cross-review process in which we invite all reviewers to read the other (still anonymous) reviews and make additional comments within 2 business days. Cross-review is encouraged, but not required. We are able to expedite the review process significantly for papers that require rapid assessment. Manuscripts selected for publication are edited to improve accuracy and clarity, as well as for length. Rejected papers cannot be resubmitted over a disagreement on novelty, interest, or relative merit. If a paper was rejected on the basis of serious reviewer error, resubmission may be considered.

Authors are notified of decisions by e-mail, and the status of the manuscript can be tracked at Membership in AAAS is not a factor in selection of manuscripts for publication. Science treats all submitted manuscripts as confidential documents. Science also instructs and expects our Board of Reviewing Editors and reviewers to treat manuscripts as confidential material. Our peer review process is confidential and identities of reviewers are not released. (Letters and Technical Comments are sent to the authors of papers on which they comment for response or rebuttal, but otherwise are treated in the same way as other contributions with respect to confidentiality.)

Science publishes five other journals: Science Signaling, Science Translational Medicine, Science Immunology, Science Robotics, and our open access, interdisciplinary journal, Science Advances. Authors submitting to Science may elect to transfer to one of our other journals should the manuscript not be selected for publication at Science. Science editors will not see this choice until after the decision is made, and authors will be given the opportunity to confirm the choice before transfer is initiated. If a manuscript is rejected from Science with the option of transfer, we would be happy to transfer your submission from Science with no reformatting required. Editors at the second journal may use the information gathered during evaluation at Science to expedite review, including reuse of the reviews provided reviewers agree. You may also choose to start a new review process. The transfer can only include documents that were part of the review process at Science. Once transfer is complete, you will have the opportunity to upload a response to the reviews where appropriate.

Most papers are published in print and online 4 to 8 weeks after acceptance. In addition, Science selects papers for earlier online publication in First Release, using the accepted version of the paper with minimal copyediting. The official publication date of these papers is the date of First Release publication. Requests for accelerated online publication should be explained to the editors in the cover letter.
