Article

An Article is a substantial novel research study, with a complex story often involving several techniques or approaches. 

Format

  • Main text – up to 3,500 words, excluding abstract, Methods, references and figure legends.
  • Abstract – up to 150 words, unreferenced. 
  • Display items – up to 6 items (figures and/or tables). 
  • Article should be divided as follows: 
    • Introduction (without heading) 
    • Results
    • Discussion
    • Methods. ​
  • Results and Methods should be divided by topical subheadings; the Discussion does not contain subheadings. 
  • References – as a guideline, we typically recommend up to 50.
  • Articles include received/accepted dates. 
  • Articles may be accompanied by supplementary information. 
  • Articles are peer reviewed.

Analysis

An Analysis is a new analysis of existing data or describes new data obtained in a comparative analysis that leads to novel and arresting conclusions of importance to a broad audience. 

Format

  • Main text – up to 3,500 words (excluding abstract, online Methods, references and figure legends).
  • Abstract – 100-150 words, unreferenced. 
  • Display items – up to 6 items (figures and/or tables). 
  • Analysis should be divided as follows: 
    • Introduction (without heading) 
    • Results
    • Discussion
    • Methods. ​
  • Results and Methods should be divided by topical subheadings; the Discussion does not contain subheadings.  
  • References – as a guideline, we typically recommend up to 50.
  • Analyses include received/accepted dates. 
  • Analyses may be accompanied by supplementary information. 
  • Analyses are peer reviewed.

Correspondence

The Correspondence section provides a forum for comment on issues relevant to the journal’s community. This format may not be used for presentation of research data or analysis. 

Format

  • Correspondence – between 500-1,000 words.
  • Display items – 1 item.
  • References – up to 10 references. Article titles are omitted from the reference list. 
  • Correspondence may be peer-reviewed at the editors’ discretion. 

Note that Correspondence pieces are not technical comments on peer-reviewed research papers; these should be submitted as Matters Arising.

Review

A Review is an authoritative, balanced and scholarly survey of recent developments in a research field. The requirement for balance need not prevent authors from proposing a specific viewpoint, but if there are controversies in the field, the authors must treat them in an even-handed way. 

The scope of a Review should be broad enough that it is not dominated by the work of a single laboratory, and particularly not by the authors' own work.

Format

  • Main text – 3,000-4,000 words.
  • Illustrations are strongly encouraged.
  • References – up to 100 (exceptions are possible in special cases). 
  • Citations – these should be selective and, in the case of particularly important studies (≤ 10% of all the references), we encourage authors to provide short annotations explaining why these are key contributions.
  • Reviews include received/accepted dates. 
  • Reviews are peer reviewed.

______________________________________________________________________________________________________________________________________

Perspective

A Perspective provides a forum for authors to discuss fast-moving or emerging topics in a scholarly way while also presenting an original, forward-looking vision. They are more thought-provoking or speculative than Reviews and may take a narrower field of view. While opinionated, Perspectives should remain balanced and are intended to stimulate discussion.

Format

  • Main text – 3,000-4,000 words.
  • References – up to 100 (exceptions are possible in special cases). 
  • Perspectives include received/accepted dates. 
  • Perspectives are peer reviewed.

Comment

A Comment is a very flexible format, focusing on the scientific, commercial, ethical, legal, societal, or political issues surrounding research. Comments should be topical, readable, provocative and introduce new concepts/points of view, providing a personal perspective on a matter of public or scientific importance. The main criteria are that they should be of immediate interest to a broad readership and should be written in an accessible, non-technical style. 

Format

  • Length – 1,500-2,000 words.
  • Comments do not normally contain primary research data, although they may present 'sociological' data (funding trends, demographics, bibliographic data, etc.). 
  • References should be used sparingly, usually between 10-25.
  • Article titles are omitted from the reference list.
  • Peer review is at the editors' discretion.

Matters Arising

Matters Arising are exceptionally interesting and timely scientific comments and clarifications on original research papers published in Nature Machine Intelligence. These comments should ideally be based on contemporary knowledge rather than subsequent scientific developments.

For detailed information on how to submit a Matters Arising, please follow instructions here.

Reusability Reports

Reusability Reports are based on the Matters Arising format but specifically test the robustness and reusability of new code that support the findings in original research papers published in Nature Machine Intelligence. Read our editorial introducing this format “Research, reuse, repeat”.

News & Views

News & Views articles inform readers about the latest advances in machine intelligence, as reported in recently published papers or at scientific meetings. They may be linked to articles in Nature Machine Intelligence, or they may focus on papers of exceptional significance that are published elsewhere. Unsolicited contributions will not normally be considered, although prospective authors are welcome to make proposals.

News & Views are not peer reviewed.

Book Review

Book Reviews are by prior arrangement only, although suggestions are welcome. Book reviews are not peer reviewed.
