How to Format a Scientific Paper

#scribendiinc

Written by  Joanna Kimmerly-Smith

You've done the research. You've carefully recorded your lab results and compiled a list of relevant sources. You've even written a draft of your scientific, technical, or medical paper, hoping to get published in a reputable journal. But how do you format your paper to ensure that every detail is correct? If you're a scientific researcher or co-author looking to get your research published, read on to find out how to format your paper.

While it's true that you'll eventually need to tailor your research for your target journal, which will provide specific author guidelines for formatting the paper (see, for example, author guidelines for publications by Elsevier , PLOS ONE , and  mBio ), there are some formatting rules that are useful to know for your initial draft. This article will explore some of the formatting rules that apply to all scientific writing, helping you to follow the correct order of sections ( IMRaD ), understand the requirements of each section, find resources for standard terminology and units of measurement, and prepare your scientific paper for publication.

Format Overview

The four main elements of a scientific paper can be represented by the acronym IMRaD: introduction, methods, results, and discussion. Other sections, along with a suggested length,* are listed in the table below.

* Length guidelines are taken from https://www.elsevier.com/connect/11-steps-to-structuring-a-science-paper-editors-will-take-seriously#step6 .

Now, let's go through the main sections you might have to prepare to format your paper.

On the first page of the paper, you must present the title of the paper along with the authors' names, institutional affiliations, and contact information. The corresponding author(s) (i.e., the one[s] who will be in contact with the reviewers) must be specified, usually with a footnote or an asterisk (*), and their full contact details (e.g., email address and phone number) must be provided. For example:

Dr. Clara A. Bell 1, * and Dr. Scott C. Smith 2

1 University of Areopagitica, Department of Biology, Sometown, Somecountry

2 Leviathan University, Department of Biochemistry and Biomedical Sciences, Sometown, Somecountry

*[email protected]

FORMATTING TIPS:

  • If you are unsure of how to classify author roles (i.e., who did what), guidelines are available online. For example, American Geophysical Union (AGU) journals now recommend using Contributor Roles Taxonomy (CRediT), an online taxonomy for author contributions.

In this summary of your research, you must state your subject (i.e., what you did) and encapsulate the main findings and conclusions of your paper.

  • Do not add citations in an abstract (the reader might not be able to access your reference list).
  • Avoid using acronyms and abbreviations in the abstract, as the reader may not be familiar with them. Use full terms instead.

Below the abstract, include a list of key terms to help other researchers locate your study. Note that "keywords" is one word (with no space) and is followed by a colon:

Keywords : paper format, scientific writing.

  • Check whether "Keywords" should be italicized and whether each term should be capitalized.
  • Check the use of punctuation (e.g., commas versus semicolons, the use of the period at the end).
  • Some journals (e.g., IEEE ) provide a taxonomy of keywords. This aids in the classification of your research.

Introduction

This is the reader's first impression of your paper, so it should be clear and concise. Include relevant background information on your topic, using in-text citations as necessary. Report new developments in the field, and state how your research fills gaps in the existing research. Focus on the specific problem you are addressing, along with its possible solutions, and outline the limitations of your study. You can also include a research question, hypothesis, and/or objectives at the end of this section.

  • Organize your information from broad to narrow (general to particular). However, don't start too broad; keep the information relevant.
  • You can use in-text citations in this section to situate your research within the body of literature.

This is the part of your paper that explains how the research was done. You should relate your research procedures in a clear, logical order (i.e., the order in which you conducted the research) so that other researchers can reproduce your results. Simply refer to the established methods you used, but describe any procedures that are original to your study in more detail.

  • Identify the specific instruments you used in your research by including the manufacturer’s name and location in parentheses.
  • Stay consistent with the order in which information is presented (e.g., quantity, temperature, stirring speed, refrigeration period).

Now that you've explained how you gathered your research, you've got to report what you actually found. In this section, outline the main findings of your research. You need not include too many details, particularly if you are using tables and figures. While writing this section, be consistent and use the smallest number of words necessary to convey your statistics.

  • Use appendices or supplementary materials if you have too much data.
  • Use headings to help the reader follow along, particularly if your data are repetitive (but check whether your style guide allows you to use them).

In this section, you interpret your findings for the reader in relation to previous research and the literature as a whole. Present your general conclusions, including an assessment of the strengths and weaknesses of the research and the implications of your findings. Resolve the hypothesis and/or research question you identified in the introduction.

  • Use in-text citations to support your discussion.
  • Do not repeat the information you presented in the results or the introduction unless it is necessary for a discussion of the overall implications of the research.

This section is sometimes included in the last paragraph of the discussion. Explain how your research fits within your field of study, and identify areas for future research.

  • Keep this section short.

Acknowledgments

Write a brief paragraph giving credit to any institution responsible for funding the study (e.g., through a fellowship or grant) and any individual(s) who contributed to the manuscript (e.g., technical advisors or editors).

  • Check whether your journal uses standard identifiers for funding agencies (e.g., Elsevier's Funder Registry ).

Conflicts of Interest/Originality Statement

Some journals require a statement attesting that your research is original and that you have no conflicts of interest (i.e., ulterior motives or ways in which you could benefit from the publication of your research). This section only needs to be a sentence or two long.

Here you list citation information for each source you used (i.e., author names, date of publication, title of paper/chapter, title of journal/book, and publisher name and location). The list of references can be in alphabetical order (author–date style of citation) or in the order in which the sources are presented in the paper (numbered citations). Follow your style guide; if no guidelines are provided, choose a citation format and be consistent .

  • While doing your final proofread, ensure that the reference list entries are consistent with the in-text citations (i.e., no missing or conflicting information).
  • Many citation styles use a hanging indent and may be alphabetized. Use the styles in Microsoft Word to aid you in citation format.
  • Use EndNote , Mendeley , Zotero , RefWorks , or another similar reference manager to create, store, and utilize bibliographic information.

Appendix/Supplementary Information

In this optional section, you can present nonessential information that further clarifies a point without burdening the body of the paper. That is, if you have too much data to fit in a (relatively) short research paper, move anything that's not essential to this section.

  • Note that this section is uncommon in published papers. Before submission, check whether your journal allows for supplementary data, and don't put any essential information in this section.

Beyond IMRaD: Formatting the Details

Aside from the overall format of your paper, there are still other details to watch out for. The sections below cover how to present your terminology, equations, tables and figures, measurements, and statistics consistently based on the conventions of scientific writing.

Terminology

Stay consistent with the terms you use. Generally, short forms can be used once the full term has been introduced:

  • full terms versus acronyms (e.g., deoxyribonucleic acid versus DNA);
  • English names versus Greek letters (e.g., alpha versus α); and
  • species names versus short forms (e.g., Staphylococcus aureus versus S. aureus ).

One way to ensure consistency is to use standard scientific terminology. You can refer to the following resources, but if you're not sure which guidelines are preferred, check with your target journal.

  • For gene classification, use GeneCards , The Mouse Genome Informatics Database , and/or genenames.org .
  • For chemical nomenclature, refer to the International Union of Pure and Applied Chemistry (IUPAC) Compendium of Chemical Terminology (the Gold Book ) and the  IUPAC–IUB Combined Commission on Biochemical Nomenclature .
  • For marine species names, use the World Register of Marine Species (WoRMS) or the European Register of Marine Species (ERMS) .

Italics must be used correctly for scientific terminology. Here are a couple of formatting tips:

  • Species names, which are usually in Greek or Latin, are italicized (e.g., Staphylococcus aureus ).
  • Genes are italicized, but proteins aren't.

Whether in mathematical, scientific, or technical papers, equations follow a conventional format. Here are some tips for formatting your calculations:

  • Number each equation you present in the text, inserting the number in parentheses.

X + Y = 1                                                                                                                                               (1)

  • Check whether your target journal requires you to capitalize the word "Equation" or use parentheses for the equation number when you refer to equations within the text.

In Equation 1, X represents . . .

In equation (1), X represents . . .

(Note also that you should use italics for variables.)

  • Try using MathType or Equation Editor in Microsoft Word to type your equations, but use Unicode characters when typing single variables or mathematical operators (e.g., x, ≥, or ±) in running text. This makes it easier to edit your text and format your equations before publication.
  • In line with the above tip, remember to save your math equations as editable text and not as images in case changes need to be made before publication.

Tables and Figures

Do you have any tables, graphs, or images in your research? If so, you should become familiar with the rules for referring to tables and figures in your scientific paper. Some examples are presented below.

  • Capitalize the titles of specific tables and figures when you refer to them in the text (e.g., "see Table 3"; "in Figure 4").
  • In tables, stay consistent with the use of title case (i.e., Capitalizing Each Word) and sentence case (i.e., Capitalizing the first word).
  • In figure captions, stay consistent with the use of punctuation, italics, and capitalization. For example:

Figure 1. Classification of author roles.

Figure 2: taxonomy of paper keywords

Measurements

Although every journal has slightly different formatting guidelines, most agree that the gold standard for units of measurement is the International System of Units (SI) . Wherever possible, use the SI. Here are some other tips for formatting units of measurement:

  • Add spaces before units of measurement. For example, 2.5 mL not 2.5mL.
  • Be consistent with your units of measure (especially date and time). For example, 3 hours or 3 h.

When presenting statistical information, you must provide enough specific information to accurately describe the relationships among your data. Nothing is more frustrating to a reviewer than vague sentences about a variable being significant without any supporting details. The author guidelines for the journal Nature recommend that the following be included for statistical testing: the name of each statistical analysis, along with its n value; an explanation of why the test was used and what is being compared; and the specific alpha levels and P values for each test.

Angel Borja, writing for Elsevier publications, described the statistical rules for article formatting as follows:

  • Indicate the statistical tests used with all relevant parameters.
  • Use mean and standard deviation to report normally distributed data.
  • Use median and interpercentile range to report skewed data.
  • For numbers, use two significant digits unless more precision is necessary.
  • Never use percentages for very small samples.

Remember, you must be prepared to justify your findings and conclusions, and one of the best ways to do this is through factual accuracy and the acknowledgment of opposing interpretations, data, and/or points of view.

Even though you may not look forward to the process of formatting your research paper, it's important to present your findings clearly, consistently, and professionally. With the right paper format, your chances of publication increase, and your research will be more likely to make an impact in your field. Don't underestimate the details. They are the backbone of scientific writing and research.

Scientific Paper: What is it & How to Write it? (Steps and Format)

' src=

A white page, and a blinking cursor: How can a blank document be so intimidating? You might hear the voice of your Ph.D. professor rumbling in your head: “Well done with the research, why don’t you put all that data together in a scientific paper so we can get it published?”

Well, it’s more challenging than it sounds!

For first-time authors, the chances of writing their own scientific research may both be overwhelming and exciting. Encountered with a mountain of notes, data, remnants of the research process, and days spent doing experiments, it may be daunting to figure out where and how to begin the process of writing a scientific paper!

The good news is, you don’t have to be a talented writer to pen-down a good scientific paper, but just have to be an organized and careful writer.

This is why we have put time and effort into creating an exceptional guide on how to write a scientific paper that will help you present your research successfully to your supervisors or publications without any clutter!

Before we begin, let’s learn about the touchstones or benchmarks of scientific writing for authors!

What is a Scientific Paper? (Definition)

A scientific paper is a manuscript that represents an original work of scientific research or study. It can be an addition to the ongoing study in a field, can be groundbreaking, or a comparative study between different approaches.

Most times, a scientific paper draws the research performed by an individual or a group of people. These papers showcase valuable analysis in fields like theoretical physics, mathematics, etc., and are routinely published in scientific journals.

3 Golden Rules of Scientific Writing

According to a study by lijunsun, scientists and writers have identified difficulties in communicating science to the public through typical scientific prose.

Scientists doing research

Simply put, it is important for researchers to maintain a balance between receiving respect and recognition for their research in a particular field and making sure that their work is understandable to a wider audience. The latter can be achieved through clarity, simplicity, and accuracy.

Bit.ai Home Page CTA

Clarity – Research is unambiguous and free of irrelevant conjecture or detail.

Simplicity – Language, sentence, and paragraph structure are easy to comprehend and follow without losing scientific credibility or authority.

Accuracy – Data, figures, tables, references, and citations are illustrated verifiably and honestly.

Why are Scientific Papers Important?

A scientific paper is both a testing device and a teaching device.

When handled correctly, it empowers you to

  • Learn and read an assignment carefully,
  • Research the nuances of your topic,
  • Refine your focus to a strong,
  • Offer arguable thesis,
  • Select the best evidence to prove the analysis of your dissertation.

As a primary teaching device, the scientific paper in your field trains you to self-learn some rules and expectations in terms of:

  • Writing format,
  • Appropriateness of language and content,
  • Submission requirements,
  • Bibliographic styles, and much more.

As you move onward with your research, you’ll find that the scientific paper quickly becomes the educational “ coin of the realm .” Hence, it’s important to approach any scientific paper with zeal for higher learning.

How to Write a Scientific Paper? (Steps & Format)

When you begin with writing your scientific manuscript, the first thing to consider is the format and order of sections in relation to your research or the information you want to showcase.

A scientific paper follows the  conventional format of research-based writing, which provides a deeper understanding of the purpose of each section. The structure starts with:

Step 1. Add Title in the Paper

A title should be of the fewest words possible, accurately describing the content of the paper. Try to eliminate unnecessary words such as “Investigations of …”, “A study of …”, “Observations on …”, etc.

An improperly titled scientific paper might never reach the readers for which it was intended. Hence, mention the name of the study, a particular region it was conducted in, or an element it contains in the title.

Step 2. Mention Keywords List

A keyword list offers the opportunity to add keywords, in addition to those already written in the title. Optimal use of keywords may increase the chances of interested parties to easily locate your scientific paper.

Step 3.  Add Abstract

A well-defined abstract allows the reader to identify the basic content of your paper quickly and accurately, to determine its relevance, and decide whether to read it in its entirety. The abstract briefly states the principal, scope, and objectives of the research. The abstract typically should not exceed 250 words. If you can convey the important details of the paper in 100 words, do not try to use more.

Step 4. Start with  Introduction

An introduction begins by introducing the authors and their relevant fields to the reader. A common mistake made is introducing their areas of study while not mentioning their major findings in descriptive scientific writing, enabling the reader to place the current work in context.

The ending of the introduction can be done through a statement of objectives or, with a brief statement of the principal findings. Either way, the reader must have an idea of where the paper is headed to process the development of the evidence.

Step 5. Mention Scientific  Materials and Methods Used

The primary purpose of the ‘Materials and Methods’ section is to provide enough detail for a competent worker to replicate your research and reproduce the results.

The scientific method requires your results to be reproducible, and provide a basis for the reiteration of the study by others. However, if case your material and method have been previously published in a journal, only the name of the study and a literature reference is needed.

Step 6. Write down  Results

Results display your findings, figures, and tables of your study. It represents the data, condensed, and digested with important trends that are extracted while researching. Since the results hold new knowledge that you are contributing to the world, it is important that your data is simply and clearly stated.

Step 7. Create a  Discussion Section

A discussion involves talking and answering about different aspects of the scientific paper such as: what principles have been established or reinforced; how your findings compare to the findings of others, what generalizations can be drawn, and whether there are any practical/theoretical implications of your research.

Students discussing a scientific paper

Step 8. Mention References

A list of references presented alphabetically by author’s surname, or number, based on the publication, must be provided at the end of your scientific paper. The reference list must contain all references cited in the text. Include author details such as the title of the article, year of publication, name of journal or book or volume, and page numbers with each reference

Now that you know the key elements to include in your scientific paper, it’s time to introduce you to an awesome tool that will make writing a scientific paper, a breeze!

Precise, accurate and clear writing is essential for communicating in health sciences, as publication is an important component in the university criteria for academic promotion and in obtaining funding to support research. In spite of this, the development of writing skills is a subject infrequently included in the curricula of faculties of medicine and allied health sciences. Therefore clinical investigators require tools to fill this gap. The present paper presents a brief historical background to medical publication and practical guidelines for writing scientific papers for acceptance in good journals.

INTRODUCTION

A scientific paper is the formal lasting record of a research process. It is meant to document research protocols, methods, results and conclusions derived from an initial working hypothesis. The first medical accounts date back to antiquity. Imhotep, Pharaoh of the 3 rd Dynasty, could be considered the founder of ancient Egyptian medicine as he has been credited with being the original author of what is now known as the Edwin Smith Papyrus ( Figure 1 ). The Papyrus, by giving some details on cures and anatomical observations, sets the basis of the examination, diagnosis, treatment, and prognosis of numerous diseases. Closer to the Common Era, in 460 BCE, Hippocrates wrote 70 books on medicine. In 1020, the Golden age of the Muslim Culture, Ibn Sina, known as Avicenna ( Figure 2a ), recorded the Canon of medicine that was to become the most used medical text in Europe and Middle East for almost half a millennium. This was followed in the beginning of the 12 th Century bytheextensivetreatiseofMaimonides( Figure 2b ) (Moses ben Maimon) on Greek and Middle Eastern medicine. Of interest, by the end of the 11 th Century Trotula di Ruggiero, a woman physician, wrote several influential books on women’s ailment. A number of other hallmark treatises also became more accessible, thanks to the introduction of the printing press that allowed standardization of the texts. One example is the De Humani Corporis Fabrica by Vesalius which contains hundreds of illustrations of human dissection. Thomas A Lang provides an excellent concise history of scientific publications [ 1 ]. These were the days when writing and publishing scientific or philosophical works were the privilege of the few and hence there was no or little competition and no recorded peer reviewing system. Times have however changed, and contemporary scientists have to compose with an increasingly harsh competition in attracting editors and publishers attention. As an example, the number of reports and reviews on obesity and diabetes has increased from 400 to close to 4000/year and 50 to 600/year respectively over a period of 20 years ( Figure 3 ). The present article, essentially based on TA Lang’s guide for writing a scientific paper [ 1 ], will summarize the steps involved in the process of writing a scientific report and in increasing the likelihood of its acceptance.

This manuscript, written in 1600 BCE, is regarded as a copy of several earlier works ( 3000 BCE). It is part of a textbook on surgery the examination, diagnosis, treatment, and prognosis of numerous ailments. BCE: Before the Common Era.

Reasons for publishing are varied. One may write to achieve a post-graduate degree, to obtain funding for pursuing research or for academic promotion. While all 3 reasons are perfectly legitimate, one must ask whether they are sufficient to be considered by editors, publishers and reviewers. Why then should the scientist write? The main reason is to provide to the scientific community data based on hypotheses that are innovative and thus to advance the understanding in a specific domain. One word of caution however, is that if a set of experiments has not been done or reported, it does not mean that it should be. It may simply reflect a lack of interest in it.

DECIDING ON PUBLISHING AND TARGETING THE JOURNAL

In order to assist with the decision process, pres-ent your work orally first to colleagues in your field who may be more experienced in publishing. This step will help you in gauging whether your work is publishable and in shaping the paper.

Targeting the journal, in which you want to present your data, is also a critical step and should be done before starting to write. One hint is to look for journals that have published similar work to yours, and that aims readers most likely to be interested in your research. This will allow your article to be well read and cited. These journals are also those that you are most likely to read on a regular basis and to cite abundantly. The next step is to decide whether you submit your manuscript to a top-ranking impact factor journal or to a journal of lower prestige. Although it is tempting to test the waters, or to obtain reviewers comments, be realistic about the contribution your work provides and submit to a journal with an appropriate rank.

Do not forget that each rejection delays publication and that the basin of reviewers within your specialty is shallow. Thus repeated submission to different journals could likely result in having your work submitted for review to the same re-viewer.

DECIDING ON THE TYPE OF MANUSCRIPT

There are several types of scientific reports: observational, experimental, methodological, theoretical and review. Observational studies include 1) single-case report, 2) collective case reports on a series of patients having for example common signs and symptoms or being followed-up with similar protocols, 3) cross-sectional, 4) cohort studies, and 5) case-control studies. The latter 3 could be perceived as epidemiological studies as they may help establishing the prevalence of a condition, and identify a defined population with and without a particular condition (disease, injury, surgical complication). Experimental reports deal with research that tests a research hypothesis through an established protocol, and, in the case of health sciences, formulate plausible explanations for changes in biological systems. Methodological reports address for example advances in analytical technology, statistical methods and diagnostic approach. Theoretical reports suggest new working hypotheses and principles that have to be supported or disproved through experimental protocols. The review category can be sub-classified as narrative, systematic and meta-analytic. Narrative reviews are often broad overviews that could be biased as they are based on the personal experience of an expert relying on articles of his or her own choice. Systematic reviews and meta-analyses are based on reproducible procedures and on high quality data. Researchers systematically identify and analyze all data collected in articles that test the same working hypothesis, avoiding selection bias, and report the data in a systematic fashion. They are particularly helpful in asking important questions in the field of healthcare and are often the initial step for innovative research. Rules or guidelines in writing such report must be followed if a quality systematic review is to be published.

For clinical research trials and systematic reviews or meta-analyses, use the Consort Statement (Consolidated Standards Of Reporting Trials) and the PRISMA Statement (Preferred Reporting Items for Systematic reviews and Meta-Analyses) respectively [ 2 , 3 ]. This assures the editors and the reviewers that essential elements of the trials and of the reviews were tackled. It also speeds the peer review process. There are several other Statements that apply to epidemiological studies [ 4 ], non-randomized clinical trials [ 5 ], diagnostic test development ( 6 ) and genetic association studies ( 7 ). The Consortium of Laboratory Medicine Journal Editors has also published guidelines for reporting industry-sponsored laboratory research ( 8 ).

INITIAL STEPS IN THE PROCESS OF WRITING A SCIENTIFIC DOCUMENT

Literature review is the initial and essential step before starting your study and writing the scientific report based on it. In this process use multiple databases, multiple keyword combinations. It will allow you to track the latest development in your field and thus avoid you to find out that someone else has performed the study before you, and hence decrease the originality of your study. Do not forget that high-ranking research journals publish results of enough importance and interest to merit their publication.

Determining the authorship and the order of authorship, an ethical issue, is the second essential step, and is unfortunately often neglected. This step may avoid later conflicts as, despite existing guidelines, it remains a sensitive issue owing to personal biases and the internal politics of institutions. The International Committee of Medical Editors has adopted the following guidelines for the biomedical sciences ( 9 ).

“Authorship credit should be based only on: 1) Substantial contributions to the conception and design, or acquisition of data, or analysis and interpretation of data; 2) Drafting the article or revising it critically for important intellectual content; and 3) Final approval of the version to be published. Conditions 1, 2 and 3 must be all met. Acquisition of funding, the collections of data, or general supervision of the research group, by themselves, do not justify authorship.” ( 9 , 10 )

The order of authorship should reflect the individual contribution to the research and to the publication, from most to least ( 11 ). The first author usually carries out the lead for the project reported. However the last author is often mistakenly perceived as the senior author. This is perpetuated from the European tradition and is discouraged. As there are divergent conventions among journals, the order of authorship order may or may not reflect the individual contributions; with the exception that the first author should be the one most responsible for the work.

WRITING EFFECTIVELY

Effective writing requires that the text helps the readers 1) understand the content and the context, 2) remember what the salient points are, 3) find the information rapidly and, 4) use or apply the information given. These cardinal qualities should be adorned with the precise usage of the language, clarity of the text, inclu-siveness of the information, and conciseness. Effective writing also means that you have to focus on the potential readers’ needs. Readers in science are informed individuals who are not passive, and who will formulate their own opinion of your writing whether or not the meaning is clear. Therefore you need to know who your audience is. The following 4 questions should help you writing a reader-based text, meaning written to meet the information needs of readers [ 12 ].

What do you assume your readers already know? In other words, which terms and concepts can you use without explanation, and which do you have to define?

What do they want to know? Readers in science will read only if they think they will learn something of value.

What do they need to know? Your text must contain all the information necessary for the reader to understand it, even if you think this information id obvious to them.

What do they think they know that is not so? Correcting misconceptions can be an important function of communication, and persuading readers to change their minds can be a challenging task.

WRITING THE SCIENTIFIC PAPER

Babbs and Tacker ’ s advice to write as much of the paper before performing the research project or experimental protocol may, at first sight, seem unexpected and counterintuitive [ 13 ], but in fact it is exactly what is being done when writing a research grant application. It will allow you to define the authorship alluded to before. The following section will briefly review the structure of the different sections of a manuscript and describe their purpose.

Reading the instructions to authors of the Journal you have decided to submit your manuscript is the first important step. They provide you with the specific requirements such as the way of listing the authors, type of abstract, word, figure or table limits and citation style. The Mulford Library of University of Toledo website contains instructions to authors for over 3000 journals ( http://mulford.meduoiho.edu/instr/ ).

The general organization of an article follows the IMRAD format (Introduction, Methods, Results, and Discussion). These may however vary. For instance, in clinical research or epidemiology studies, the methods section will include details on the subjects included, and there will be a statement of the limitation of the study. Although conclusions may not always be part of the structure, we believe that it should, even in methodological reports.

The tile page provides essential information so that the editor, reviewers, and readers will identify the manuscript and the authors at a glance as well as enabling them to classify the field to which the article pertains.

The title page must contain the following:

  • The tile of the article – it is an important part of the manuscript as it is the most often read and will induce the interested readers to pursue further. Therefore the title should be precise, accurate, specific and truthful;
  • Each author’s given name (it may be the full name or initials) and family name;
  • Each author’s affiliation;
  • Some journals ask for highest academic degree;
  • A running title that is usually limited to a number of characters. It must relate to the full title;
  • Key words that will serve for indexing;
  • For clinical studies, the trial’s registration number;
  • The name of the corresponding author with full contact information.

The abstract is also an important section of your manuscript. Importantly, the abstract is the part of the article that your peers will see when consulting publication databases such as PubMed. It is the advertisement to your work and will strongly influence the editor deciding whether it will be submitted to reviewers or not. It will also help the readers decide to read the full article. Hence it has to be comprehensible on its own. Writing an abstract is challenging. You have to carefully select the content and, while being concise, assure to deliver the essence of your manuscript.

Without going into details, there are 3 types of abstracts: descriptive, informative and structured. The descriptive abstract is particularly used for theoretical, methodological or review articles. It usually consists of a single paragraph of 150 words or less. The informative abstract, the most common one, contains specific information given in the article and, are organized with an introduction (background, objectives), methods, results and discussion with or without conclusion. They usually are 150 to 250 words in length. The structured abstract is in essence an informative abstract with sections labeled with headings. They may also be longer and are limited to 250 to 300 words. Recent technology also allows for graphical or even video abstracts. The latter are interesting in the context of cell biology as they enable the investigator to illustrate ex vivo experiment results (phagocytosis process for example).

Qualities of abstracts:

  • Understood without reading the full paper. Shoul dcontain no abbreviations.lf abbreviations are used, they must be defined. This however removes space for more important information;
  • Contains information consistent with the full report. Conclusions in the abstract must match those given in the full report;
  • Is attractive and contains information needed to decide whether to read the full report.

Introduction

The introduction has 3 main goals: to establish the need and importance of your research, to indicate how you have filled the knowledge gap in your field and to give your readers a hint of what they will learn when reading your paper. To fulfil these goals, a four-part introduction consisting of a background statement, a problem statement, an activity statement and a forecasting statement, is best suited. Poorly defined background information and problem setting are the 2 most common weaknesses encountered in introductions. They stem from the false perception that peer readers know what the issue is and why the study to solve it is necessary. Although not a strict rule, the introduction in clinical science journals should target only references needed to establish the rationale for the study and the research protocol. This differ from more basic science or cell biology journals, for which a longer and elaborate introduction may be justified because the research at hand consists of several approaches each requiring background and justification.

The 4-part introduction consists of:

  • A background statement that provides the context and the approach of the research;
  • A problem statement that describes the nature, scope and importance of the problem or the knowledge gap;
  • An activity statement, that details the research question, sets the hypothesis and actions undertaken for the investigation;
  • A forecasting statement telling the readers whattheywillfìndwhen readingyourarticle [ 14 ].

Methods section

This section may be named “Materials and Methods”, “Experimental section” or “Patients and Methods” depending upon the type of journal. Its purpose to allow your readers to provide enough information on the methods used for your research and to judge on their adequacy. Although clinical and “basic” research protocols differ, the principles involved in describing the methods share similar features. Hence, the breadth of what is being studied and how the study can be performed is common to both. What differ are the specific settings. For example, when a study is conducted on humans, you must provide, up front, assurance that it has received the approval of you Institution Ethics Review Board (IRB) and that participants have provided full and informed consent. Similarly when the study involves animals, you must affirm that you have the agreement from your Institutional Animal Care and Use Committee (IACUC). These are too often forgotten, and Journals (most of them) abiding to the rules of the Committee on Publication Ethics (COPE) and World Association of Medical Editors (WAME) will require such statement. Although journals publishing research reports in more fundamental science may not require such assurance, they do however also follow to strict ethics rules related to scientific misconduct or fraud such as data fabrication, data falsification. For clinical research papers, you have to provide information on how the participants were selected, identify the possible sources of bias and confounding factors and how they were diminished.

In terms of the measurements, you have to clearly identify the materials used as well as the suppliers with their location. You should also be unambiguous when describing the analytical method. If the method has already been published, give a brief account and refer to the original publication (not a review in which the method is mentioned without a description). If you have modified it, you have to provide a detailed account of the modifications and you have to validate its accuracy, precision and repeatability. Mention the units in which results are reported and, if necessary, include the conversion factors [mass units versus “système international” (S.I.)]. In clinical research, surrogate end-points are often used as biomarkers. Under those circumstances, you must show their validity or refer to a study that has already shown that are valid.

In cases of clinical trials, the Methods section should include the study design, the patient selection mode, interventions, type of outcomes.

Statistics are important in assuring the quality of the research project. Hence, you should consult a biostatistician at the time of devising the research protocol and not after having performed the experiments or the clinical trial.

The components of the section on statistics should include:

  • The way the data will be reported (mean, median, centiles for continuous data);
  • Details on participant assignments to the different groups (random allocation, consecutive entry);
  • Statistical comparison tools (parametric or non parametric statistics, paired or unpaired t-tests for normally distributed data and so on);
  • The statistical power calculation when determining the sample size to obtain valid and significant comparisons together with the a level;
  • The statistical software package used in the analysis.

Results section

The main purpose of the results section is to report the data that were collected and their relationship. It should also provide information on the modifications that have taken place because of unforeseen events leading to a modification of the initial protocol (loss of participants, reagent substitution, loss of data).

  • Report results as tables and figures whenever possible, avoid duplication in the text. The text should summarize the findings;
  • Report the data with the appropriate descriptive statistics;
  • Report any unanticipated events that could affect the results;
  • Report a complete account of observations and explanations for missing data (patient lost).

The discussion should set your research in context, reinforce its importance and show how your results have contributed to the further understanding of the problem posed. This should appear in the concluding remarks. The following organization could be helpful.

  • Briefly summarize the main results of your study in one or two paragraphs, and how they support your working hypothesis;
  • Provide an interpretation of your results and show how they logically fit in an overall scheme (biological or clinical);
  • Describe how your results compare with those of other investigators, explain the differences observed;
  • Discuss how your results may lead to a new hypothesis and further experimentation, or how they could enhance the diagnostic procedures.
  • Provide the limitations of your study and steps taken to reduce them. This could be placed in the concluding remarks.

Acknowledgements

The acknowledgements are important as they identify and thank the contributors to the study, who do not meet the criteria as co-authors. They also include the recognition of the granting agency. In this case the grant award number and source is usually included.

Declaration of competing interests

Competing interests arise when the author has more than one role that may lead to a situation where there is a conflict of interest. This is observed when the investigator has a simultaneous industrial consulting and academic position. In that case the results may not be agreeable to the industrial sponsor, who may impose a veto on publication or strongly suggest modifications to the conclusions. The investigator must clear this issue before starting the contracted research. In addition, the investigator may own shares or stock in the company whose product forms the basis of the study. Such conflicts of interest must be declared so that they are apparent to the readers.

The authors thank Thomas A Lang, for his advice in the preparation of this manuscript.

what is scientific paper format

Writing the Scientific Paper

When you write about scientific topics to specialists in a particular scientific field, we call that scientific writing. (When you write to non-specialists about scientific topics, we call that science writing.)

The scientific paper has developed over the past three centuries into a tool to communicate the results of scientific inquiry. The main audience for scientific papers is extremely specialized. The purpose of these papers is twofold: to present information so that it is easy to retrieve, and to present enough information that the reader can duplicate the scientific study. A standard format with six main part helps readers to find expected information and analysis:

  • Title--subject and what aspect of the subject was studied.
  • Abstract--summary of paper: The main reason for the study, the primary results, the main conclusions
  • Introduction-- why the study was undertaken
  • Methods and Materials-- how the study was undertaken
  • Results-- what was found
  • Discussion-- why these results could be significant (what the reasons might be for the patterns found or not found)

There are many ways to approach the writing of a scientific paper, and no one way is right. Many people, however, find that drafting chunks in this order works best: Results, Discussion, Introduction, Materials & Methods, Abstract, and, finally, Title.

The title should be very limited and specific. Really, it should be a pithy summary of the article's main focus.

  • "Renal disease susceptibility and hypertension are under independent genetic control in the fawn hooded rat"
  • "Territory size in Lincoln's Sparrows ( Melospiza lincolnii )"
  • "Replacement of deciduous first premolars and dental eruption in archaeocete whales"
  • "The Radio-Frequency Single-Electron Transistor (RF-SET): A Fast and Ultrasensitive Electrometer"

This is a summary of your article. Generally between 50-100 words, it should state the goals, results, and the main conclusions of your study. You should list the parameters of your study (when and where was it conducted, if applicable; your sample size; the specific species, proteins, genes, etc., studied). Think of the process of writing the abstract as taking one or two sentences from each of your sections (an introductory sentence, a sentence stating the specific question addressed, a sentence listing your main techniques or procedures, two or three sentences describing your results, and one sentence describing your main conclusion).

Example One

Hypertension, diabetes and hyperlipidemia are risk factors for life-threatening complications such as end-stage renal disease, coronary artery disease and stroke. Why some patients develop complications is unclear, but only susceptibility genes may be involved. To test this notion, we studied crosses involving the fawn-hooded rat, an animal model of hypertension that develops chronic renal failure. Here, we report the localization of two genes, Rf-1 and Rf-2 , responsible for about half of the genetic variation in key indices of renal impairment. In addition, we localize a gene, Bpfh-1 , responsible for about 26% of the genetic variation in blood pressure. Rf-1 strongly affects the risk of renal impairment, but has no significant effect on blood pressure. Our results show that susceptibility to a complication of hypertension is under at least partially independent genetic control from susceptibility to hypertension itself.

Example Two

We studied survival of 220 calves of radiocollared moose ( Alces alces ) from parturition to the end of July in southcentral Alaska from 1994 to 1997. Prior studies established that predation by brown bears ( Ursus arctos ) was the primary cause of mortality of moose calves in the region. Our objectives were to characterize vulnerability of moose calves to predation as influenced by age, date, snow depths, and previous reproductive success of the mother. We also tested the hypothesis that survival of twin moose calves was independent and identical to that of single calves. Survival of moose calves from parturition through July was 0.27 ± 0.03 SE, and their daily rate of mortality declined at a near constant rate with age in that period. Mean annual survival was 0.22 ± 0.03 SE. Previous winter's snow depths or survival of the mother's previous calf was not related to neonatal survival. Selection for early parturition was evidenced in the 4 years of study by a 6.3% increase in the hazard of death with each daily increase in parturition date. Although there was no significant difference in survival of twin and single moose calves, most twins that died disappeared together during the first 15 days after birth and independently thereafter, suggesting that predators usually killed both when encountered up to that age.

Example Three

We monitored breeding phenology and population levels of Rana yavapaiensis by use of repeated egg mass censuses and visual encounter surveys at Agua Caliente Canyon near Tucson, Arizona, from 1994 to 1996. Adult counts fluctuated erratically within each year of the study but annual means remained similar. Juvenile counts peaked during the fall recruitment season and fell to near zero by early spring. Rana yavapaiensis deposited eggs in two distinct annual episodes, one in spring (March-May) and a much smaller one in fall (September-October). Larvae from the spring deposition period completed metamorphosis in earlv summer. Over the two years of study, 96.6% of egg masses successfully produced larvae. Egg masses were deposited during periods of predictable, moderate stream flow, but not during seasonal periods when flash flooding or drought were likely to affect eggs or larvae. Breeding phenology of Rana yavapaiensis is particularly well suited for life in desert streams with natural flow regimes which include frequent flash flooding and drought at predictable times. The exotic predators of R. yavapaiensis are less able to cope with fluctuating conditions. Unaltered stream flow regimes that allow natural fluctuations in stream discharge may provide refugia for this declining ranid frog from exotic predators by excluding those exotic species that are unable to cope with brief flash flooding and habitat drying.

Introduction

The introduction is where you sketch out the background of your study, including why you have investigated the question that you have and how it relates to earlier research that has been done in the field. It may help to think of an introduction as a telescoping focus, where you begin with the broader context and gradually narrow to the specific problem addressed by the report. A typical (and very useful) construction of an introduction proceeds as follows:

"Echimyid rodents of the genus Proechimys (spiny rats) often are the most abundant and widespread lowland forest rodents throughout much of their range in the Neotropics (Eisenberg 1989). Recent studies suggested that these rodents play an important role in forest dynamics through their activities as seed predators and dispersers of seeds (Adler and Kestrell 1998; Asquith et al 1997; Forget 1991; Hoch and Adler 1997)." (Lambert and Adler, p. 70)

"Our laboratory has been involved in the analysis of the HLA class II genes and their association with autoimmune disorders such as insulin-dependent diabetes mellitus. As part of this work, the laboratory handles a large number of blood samples. In an effort to minimize the expense and urgency of transportation of frozen or liquid blood samples, we have designed a protocol that will preserve the integrity of lymphocyte DNA and enable the transport and storage of samples at ambient temperatures." (Torrance, MacLeod & Hache, p. 64)

"Despite the ubiquity and abundance of P. semispinosus , only two previous studies have assessed habitat use, with both showing a generalized habitat use. [brief summary of these studies]." (Lambert and Adler, p. 70)

"Although very good results have been obtained using polymerase chain reaction (PCR) amplification of DNA extracted from dried blood spots on filter paper (1,4,5,8,9), this preservation method yields limited amounts of DNA and is susceptible to contamination." (Torrance, MacLeod & Hache, p. 64)

"No attempt has been made to quantitatively describe microhabitat characteristics with which this species may be associated. Thus, specific structural features of secondary forests that may promote abundance of spiny rats remains unknown. Such information is essential to understand the role of spiny rats in Neotropical forests, particularly with regard to forest regeneration via interactions with seeds." (Lambert and Adler, p. 71)

"As an alternative, we have been investigating the use of lyophilization ("freeze-drying") of whole blood as a method to preserve sufficient amounts of genomic DNA to perform PCR and Southern Blot analysis." (Torrance, MacLeod & Hache, p. 64)

"We present an analysis of microhabitat use by P. semispinosus in tropical moist forests in central Panama." (Lambert and Adler, p. 71)

"In this report, we summarize our analysis of genomic DNA extracted from lyophilized whole blood." (Torrance, MacLeod & Hache, p. 64)

Methods and Materials

In this section you describe how you performed your study. You need to provide enough information here for the reader to duplicate your experiment. However, be reasonable about who the reader is. Assume that he or she is someone familiar with the basic practices of your field.

It's helpful to both writer and reader to organize this section chronologically: that is, describe each procedure in the order it was performed. For example, DNA-extraction, purification, amplification, assay, detection. Or, study area, study population, sampling technique, variables studied, analysis method.

Include in this section:

  • study design: procedures should be listed and described, or the reader should be referred to papers that have already described the used procedure
  • particular techniques used and why, if relevant
  • modifications of any techniques; be sure to describe the modification
  • specialized equipment, including brand-names
  • temporal, spatial, and historical description of study area and studied population
  • assumptions underlying the study
  • statistical methods, including software programs

Example description of activity

Chromosomal DNA was denatured for the first cycle by incubating the slides in 70% deionized formamide; 2x standard saline citrate (SSC) at 70ºC for 2 min, followed by 70% ethanol at -20ºC and then 90% and 100% ethanol at room temperature, followed by air drying. (Rouwendal et al ., p. 79)

Example description of assumptions

We considered seeds left in the petri dish to be unharvested and those scattered singly on the surface of a tile to be scattered and also unharvested. We considered seeds in cheek pouches to be harvested but not cached, those stored in the nestbox to be larderhoarded, and those buried in caching sites within the arena to be scatterhoarded. (Krupa and Geluso, p. 99)

Examples of use of specialized equipment

  • Oligonucleotide primers were prepared using the Applied Biosystems Model 318A (Foster City, CA) DNA Synthesizer according to the manufacturers' instructions. (Rouwendal et al ., p.78)
  • We first visually reviewed the complete song sample of an individual using spectrograms produced on a Princeton Applied Research Real Time Spectrum Analyzer (model 4512). (Peters et al ., p. 937)

Example of use of a certain technique

Frogs were monitored using visual encounter transects (Crump and Scott, 1994). (Sartorius and Rosen, p. 269)

Example description of statistical analysis

We used Wilcox rank-sum tests for all comparisons of pre-experimental scores and for all comparisons of hue, saturation, and brightness scores between various groups of birds ... All P -values are two-tailed unless otherwise noted. (Brawner et al ., p. 955)

This section presents the facts--what was found in the course of this investigation. Detailed data--measurements, counts, percentages, patterns--usually appear in tables, figures, and graphs, and the text of the section draws attention to the key data and relationships among data. Three rules of thumb will help you with this section:

  • present results clearly and logically
  • avoid excess verbiage
  • consider providing a one-sentence summary at the beginning of each paragraph if you think it will help your reader understand your data

Remember to use table and figures effectively. But don't expect these to stand alone.

Some examples of well-organized and easy-to-follow results:

  • Size of the aquatic habitat at Agua Caliente Canyon varied dramatically throughout the year. The site contained three rockbound tinajas (bedrock pools) that did not dry during this study. During periods of high stream discharge seven more seasonal pools and intermittent stretches of riffle became available. Perennial and seasonal pool levels remained stable from late February through early May. Between mid-May and mid-July seasonal pools dried until they disappeared. Perennial pools shrank in surface area from a range of 30-60 m² to 3-5- M². (Sartorius and Rosen, Sept. 2000: 269)

Notice how the second sample points out what is important in the accompanying figure. It makes us aware of relationships that we may not have noticed quickly otherwise and that will be important to the discussion.

A similar test result is obtained with a primer derived from the human ß-satellite... This primer (AGTGCAGAGATATGTCACAATG-CCCC: Oligo 435) labels 6 sites in the PRINS reaction: the chromosomes 1, one pair of acrocentrics and, more weakly, the chromosomes 9 (Fig. 2a). After 10 cycles of PCR-IS, the number of sites labeled has doubled (Fig. 2b); after 20 cycles, the number of sites labeled is the same but the signals are stronger (Fig. 2c) (Rouwendal et al ., July 93:80).

Related Information: Use Tables and Figures Effectively

Do not repeat all of the information in the text that appears in a table, but do summarize it. For example, if you present a table of temperature measurements taken at various times, describe the general pattern of temperature change and refer to the table.

"The temperature of the solution increased rapidly at first, going from 50º to 80º in the first three minutes (Table 1)."

You don't want to list every single measurement in the text ("After one minute, the temperature had risen to 55º. After two minutes, it had risen to 58º," etc.). There is no hard and fast rule about when to report all measurements in the text and when to put the measurements in a table and refer to them, but use your common sense. Remember that readers have all that data in the accompanying tables and figures, so your task in this section is to highlight key data, changes, or relationships.

In this section you discuss your results. What aspect you choose to focus on depends on your results and on the main questions addressed by them. For example, if you were testing a new technique, you will want to discuss how useful this technique is: how well did it work, what are the benefits and drawbacks, etc. If you are presenting data that appear to refute or support earlier research, you will want to analyze both your own data and the earlier data--what conditions are different? how much difference is due to a change in the study design, and how much to a new property in the study subject? You may discuss the implication of your research--particularly if it has a direct bearing on a practical issue, such as conservation or public health.

This section centers on speculation . However, this does not free you to present wild and haphazard guesses. Focus your discussion around a particular question or hypothesis. Use subheadings to organize your thoughts, if necessary.

This section depends on a logical organization so readers can see the connection between your study question and your results. One typical approach is to make a list of all the ideas that you will discuss and to work out the logical relationships between them--what idea is most important? or, what point is most clearly made by your data? what ideas are subordinate to the main idea? what are the connections between ideas?

Achieving the Scientific Voice

Eight tips will help you match your style for most scientific publications.

  • Develop a precise vocabulary: read the literature to become fluent, or at least familiar with, the sort of language that is standard to describe what you're trying to describe.
  • Once you've labeled an activity, a condition, or a period of time, use that label consistently throughout the paper. Consistency is more important than creativity.
  • Define your terms and your assumptions.
  • Include all the information the reader needs to interpret your data.
  • Remember, the key to all scientific discourse is that it be reproducible . Have you presented enough information clearly enough that the reader could reproduce your experiment, your research, or your investigation?
  • When describing an activity, break it down into elements that can be described and labeled, and then present them in the order they occurred.
  • When you use numbers, use them effectively. Don't present them so that they cause more work for the reader.
  • Include details before conclusions, but only include those details you have been able to observe by the methods you have described. Do not include your feelings, attitudes, impressions, or opinions.
  • Research your format and citations: do these match what have been used in current relevant journals?
  • Run a spellcheck and proofread carefully. Read your paper out loud, and/ or have a friend look over it for misspelled words, missing words, etc.

Applying the Principles, Example 1

The following example needs more precise information. Look at the original and revised paragraphs to see how revising with these guidelines in mind can make the text clearer and more informative:

Before: Each male sang a definite number of songs while singing. They start with a whistle and then go from there. Each new song is always different, but made up an overall repertoire that was completed before starting over again. In 16 cases (84%), no new songs were sung after the first 20, even though we counted about 44 songs for each bird.
After: Each male used a discrete number of song types in his singing. Each song began with an introductory whistle, followed by a distinctive, complex series of fluty warbles (Fig. 1). Successive songs were always different, and five of the 19 males presented their entire song repertoire before repeating any of their song types (i.e., the first IO recorded songs revealed the entire repertoire of 10 song types). Each song type recurred in long sequences of singing, so that we could be confident that we had recorded the entire repertoire of commonly used songs by each male. For 16 of the 19 males, no new song types were encountered after the first 20 songs, even though we analyzed and average of 44 songs/male (range 30-59).

Applying the Principles, Example 2

In this set of examples, even a few changes in wording result in a more precise second version. Look at the original and revised paragraphs to see how revising with these guidelines in mind can make the text clearer and more informative:

Before: The study area was on Mt. Cain and Maquilla Peak in British Columbia, Canada. The study area is about 12,000 ha of coastal montane forest. The area is both managed and unmanaged and ranges from 600-1650m. The most common trees present are mountain hemlock ( Tsuga mertensiana ), western hemlock ( Tsuga heterophylla ), yellow cedar ( Chamaecyparis nootkatensis ), and amabilis fir ( Abies amabilis ).
After: The study took place on Mt. Cain and Maquilla Peak (50'1 3'N, 126'1 8'W), Vancouver Island, British Columbia. The study area encompassed 11,800 ha of coastal montane forest. The landscape consisted of managed and unmanaged stands of coastal montane forest, 600-1650 m in elevation. The dominant tree species included mountain hemlock ( Tsuga mertensiana ), western hemlock ( Tsuga heterophylla ), yellow cedar ( Chamaecyparis nootkatensis ), and amabilis fir ( Abies amabilis ).

Two Tips for Sentence Clarity

Although you will want to consider more detailed stylistic revisions as you become more comfortable with scientific writing, two tips can get you started:

First, the verb should follow the subject as soon as possible.

Really Hard to Read : "The smallest of the URF's (URFA6L), a 207-nucleotide (nt) reading frame overlapping out of phase the NH2- terminal portion of the adenosinetriphosphatase (ATPase) subunit 6 gene has been identified as the animal equivalent of the recently discovered yeast H+-ATPase subunit gene."

Less Hard to Read : "The smallest of the UR-F's is URFA6L, a 207-nucleotide (nt) reading frame overlapping out of phase the NH2-terminal portion of the adenosinetriphosphatase (ATPase) subunit 6 gene; it has been identified as the animal equivalent of the recently discovered yeast H+-ATPase subunit 8 gene."

Second, place familiar information first in a clause, a sentence, or a paragraph, and put the new and unfamiliar information later.

More confusing : The epidermis, the dermis, and the subcutaneous layer are the three layers of the skin. A layer of dead skin cells makes up the epidermis, which forms the body's shield against the world. Blood vessels, carrying nourishment, and nerve endings, which relay information about the outside world, are found in the dermis. Sweat glands and fat cells make up the third layer, the subcutaneous layer.

Less confusing : The skin consists of three layers: the epidermis, the dermis, and the subcutaneous layer. The epidermis is made up of dead skin cells, and forms a protective shield between the body and the world. The dermis contains the blood vessels and nerve endings that nourish the skin and make it receptive to outside stimuli. The subcutaneous layer contains the sweat glands and fat cells which perform other functions of the skin.

Formatting guide

This guide describes how to prepare contributions for submission. We recommend you read this in full if you have not previously submitted a contribution to Nature . We also recommend that, before submission, you familiarize yourself with Nature ’s style and content by reading the journal, either in print or online, particularly if you have not submitted to the journal recently.

Formats for Nature contributions

Articles are the main format for original research contributions to Nature . In addition, Nature publishes other submitted material as detailed below.

Articles are original reports whose conclusions represent a substantial advance in understanding of an important problem and have immediate, far-reaching implications. In print, physical sciences papers do not normally exceed 6 pages on average, and biological, clinical and social-sciences papers do not normally exceed 8 pages on average. However, the final print length is at the editor’s discretion.

Articles start with a fully referenced summary paragraph, ideally of no more than 200 words, which is separate from the main text and avoids numbers, abbreviations, acronyms or measurements unless essential. It is aimed at readers outside the discipline. This summary paragraph should be structured as follows: 2-3 sentences of basic-level introduction to the field; a brief account of the background and rationale of the work; a statement of the main conclusions (introduced by the phrase 'Here we show' or its equivalent); and finally, 2-3 sentences putting the main findings into general context so it is clear how the results described in the paper have moved the field forwards. Please refer to our annotated example   to see how the summary paragraph should be constructed.

The typical length of a 6-page article with 4 modest display items (figures and tables) is 2500 words (summary paragraph plus body text). The typical length of an 8-page article with 5-6 modest display items is 4300 words. A ‘modest’ display item is one that, with its legend, occupies about a quarter of a page (equivalent to ~270 words). If a composite figure (with several panels) needs to occupy at least half a page in order for all the elements to be visible, the text length may need to be reduced accordingly to accommodate such figures. Keep in mind that essential but technical details can be moved into the Methods or Supplementary Information.

As a guideline, articles typically have no more than 50 references. (There is no such constraint on any additional references associated with Methods or Supplementary Information.)

Sections are separated with subheadings to aid navigation. Subheadings may be up to 40 characters (including spaces).

Word counts refer to the text of the paper. Title, author list, acknowledgements and references are not included in total word counts.

Matters Arising and Corrections

Matters Arising are exceptionally interesting or important comments and clarifications on original research papers or other peer-reviewed material published within the past 18 months in Nature . They are published online but not in print.

For further details of and instructions for how to submit such comments on peer-reviewed material published in Nature — or to notify editors of the potential need for a correction — please consult our Matters Arising page.

The editorial process

See this section for an explanation of Nature 's editorial criteria for publication, refereeing policy and how editors handle papers after submission. Submission to a Nature journal is taken by the journal to mean that all the listed authors have agreed to all of the contents. See authorship policy for more details.

Presubmission enquiries

If you wish to enquire whether your Article might be suitable for consideration by Nature , please use our online presubmission enquiry service . All presubmission enquiries must include a cover paragraph to the editor stating the interest to a broad scientific readership, a fully referenced summary paragraph, and a reference list.

Readability

Nature is an international journal covering all the sciences. Contributions should therefore be written clearly and simply so that they are accessible to readers in other disciplines and to readers for whom English is not their first language. Thus, technical jargon should be avoided as far as possible and clearly explained where its use is unavoidable. Abbreviations, particularly those that are not standard, should also be kept to a minimum. The background, rationale and main conclusions of the study should be clearly explained. Titles and abstracts in particular should be written in language that will be readily intelligible to any scientist. Essential but specialized terms should be explained concisely but not didactically.

For gene, protein and other specialized names authors can use their preferred terminology so long as it is in current use by the community, but they must give all known names for the entity at first use in the paper. Nature prefers authors to use internationally agreed nomenclature. Papers containing new or revised formal taxonomic nomenclature for animals, whether living or extinct, are accepted conditional on the provision of LSIDs (Life Science Identifiers) by means of registration of such nomenclature with ZooBank, the proposed online registration system for the International Code of Zoological Nomenclature (ICZN).

Even though no paper will be rejected because of poor language, non–native English speakers occasionally receive feedback from editors and reviewers regarding language and grammar usage in their manuscripts. You may wish to consider asking colleagues to read your manuscript and/or to use a professional editing service such as those provided by our affiliates Nature Research Editing Service or American Journal Experts . You can also get a fast, free grammar check of your manuscript that takes into account all aspects of readability in English. Please note that the use of a language editing service is not a requirement for publication in Nature .

Nature 's editors provide detailed advice about the expected print length when asking for the final version of the manuscript. Nature 's editors often suggest revised titles and rewrite the summary paragraphs of Articles so the conclusions are clear to a broad readership.

After acceptance, Nature 's subeditors (copyeditors) ensure that the text and figures are readable and clear to those outside the field, and edit papers into Nature 's house style. They pay particular attention to summary paragraphs, overall clarity, figures, figure legends and titles.

Proofs are sent before publication; authors are welcome to discuss proposed changes with Nature 's subeditors, but Nature reserves the right to make the final decision about matters of style and the size of figures.

A useful set of articles providing general advice about writing and submitting scientific papers can be found on the SciDev.Net website.

Format of Articles

Contributions should be double-spaced and written in English (spellings as in the Oxford English Dictionary ).

Contributions should be organized in the sequence: title, authors, affiliations (plus present addresses), bold first paragraph, main text, main references, tables, figure legends, methods (including separate data and code availability statements), methods references, acknowledgements, author contributions, competing interest declaration, additional information (containing supplementary information line (if any) and corresponding author line), extended data figure/table legends. In order to facilitate the review process, for initial submissions we encourage authors to present the manuscript text and figures together in a single file (Microsoft Word or PDF, up to 30 MB in size). The figures may be inserted within the text at the appropriate positions or grouped at the end, and each figure legend should be presented together with its figure. Also, please include line numbers within the text.

Titles do not exceed two lines in print. This equates to 75 characters (including spaces). Titles do not normally include numbers, acronyms, abbreviations or punctuation. They should include sufficient detail for indexing purposes but be general enough for readers outside the field to appreciate what the paper is about.

An uninterrupted page of text contains about 1250 words.

A typical 6-page Article contains about 2,500 words of text and, additionally, 4 modest display items (figures and/or tables) with brief legends, reference list and online-only methods section if applicable. A composite figure (with several panels) usually needs to take about half a page, equivalent to about 600 words, in order for all the elements to be visible (see section 5.9 for instructions on sizing figures).

A typical 8-page Article contains about 4300 words of text and, additionally, 5-6 modest display items (figures and/or tables) with brief legends, reference list and online-only methods section if applicable. A composite figure (with several panels) usually needs to take about half a page, equivalent to about 600 words, in order for all the elements to be visible (see section 5.9 for instructions on sizing figures).

Authors of contributions that significantly exceed the limits stated here (or as specified by the editor) will have to shorten their papers before acceptance, inevitably delaying publication.

Nature requires authors to specify the contribution made by their co-authors in the end notes of the paper (see section 5.5). If authors regard it as essential to indicate that two or more co-authors are equal in status, they may be identified by an asterisk symbol with the caption ‘These authors contributed equally to this work’ immediately under the address list. If more than three co-authors are equal in status, this should be indicated in the author contributions statement. Present addresses appear immediately below the author list (below the footnote rule at the bottom of the first page) and may be identified by a dagger symbol; all other essential author-related explanation is placed in the acknowledgements.

Our preferred format for text is Microsoft Word, with the style tags removed.

TeX/LaTeX: If you have prepared your paper using TeX/LaTeX, we will need to convert this to Word after acceptance, before your paper can be typeset. All textual material of the paper (including references, tables, figure captions, online methods, etc.) should be included as a single .tex file.

We prefer the use of a ‘standard’ font, preferably 12-point Times New Roman. For mathematical symbols, Greek letters and other special characters, use normal text or Symbol font. Word Equation Editor/MathType should be used only for formulae that cannot be produced using normal text or Symbol font.

The ‘Methods’ section is in the main text file, following the figure legends. This Methods section will appear in the PDF and in the full-text (HTML) version of the paper online, but will not appear in the printed issue. The Methods section should be written as concisely as possible but should contain all elements necessary to allow interpretation and replication of the results. As a guideline, the Methods section does not typically exceed 3,000 words. To increase reproducibility, authors are encouraged to deposit a detailed description of protocols used in their study in a protocol sharing platform of their choice. Nature Portfolio’s Protocol Exchange is a free and open service designed to help researchers share experimental know-how. Protocols deposited by the authors in Protocol Exchange will be linked to the online Methods section upon publication.

Detailed descriptions of methods already published should be avoided; a reference number can be provided to save space, with any new addition or variation stated.

The Methods section should be subdivided by short bold headings referring to methods used and we encourage the inclusion of specific subsections for statistics, reagents and animal models. If further references are included in this section their numbering should continue from the end of the last reference number in the rest of the paper and they are listed after the Methods section.

Please provide separate Data Availability and Code Availability statements after the main text statements and before the Extended Data legends; detailed guidance can be found in our data availability and data citations policy . Certain data types must be deposited in an appropriate public structured data depository (details are available here ), and the accession number(s) provided in the manuscript. Full access is required at the time of publication. Should full access to data be required for peer review, authors must provide it.

The Methods section cannot contain figures or tables (essential display items should be included in the Extended Data or exceptionally in the Supplementary Information).

References are each numbered, ordered sequentially as they appear in the text, tables, boxes, figure legends, Methods, Extended Data tables and Extended Data figure legends.

When cited in the text, reference numbers are superscript, not in brackets unless they are likely to be confused with a superscript number.

Do not use linked fields (produced by EndNote and similar programs). Please use the one-click button provided by EndNote to remove EndNote codes before saving your file.

As a guideline, Articles allow up to 50 references in the main text if needed and within the average page budget. Only one publication can be listed for each number. Additional references for Methods or Supplementary Information are not included in this count.

Only articles that have been published or accepted by a named publication, or that have been uploaded to a recognized preprint server (for example, arXiv, bioRxiv), should be in the reference list; papers in preparation should be mentioned in the text with a list of authors (or initials if any of the authors are co-authors of the present contribution).

Published conference abstracts, numbered patents, preprints on recognized servers, papers in press, and research datasets that have been assigned a digital object identifier may be included in reference lists, but text, grant details and acknowledgements may not. (An exception is the highlighted references which we ask authors of Reviews, Perspectives and Insights articles to provide.)

All authors should be included in reference lists unless there are more than five, in which case only the first author should be given, followed by ‘et al.’.

Please follow the style below in the published edition of Nature in preparing reference lists.

Authors should be listed surname first, followed by a comma and initials of given names.

Titles of all cited articles are required. Titles of articles cited in reference lists should be in upright, not italic text; the first word of the title is capitalized, the title written exactly as it appears in the work cited, ending with a full stop. Book titles are italic with all main words capitalized. Journal titles are italic and abbreviated according to common usage. Volume numbers are bold. The publisher and city of publication are required for books cited. (Refer to published papers in Nature for details.)

Research datasets may be cited in the reference list if they have been assigned digital object identifiers (DOIs) and include authors, title, publisher (repository name), identifier (DOI expressed as a URL). Example: Hao, Z., AghaKouchak, A., Nakhjiri, N. & Farahmand, A. Global Integrated Drought Monitoring and Prediction System (GIDMaPS) data sets. figshare http://dx.doi.org/10.6084/m9.figshare.853801 (2014).

Recognized preprints may be cited in the reference list. Example: Babichev, S. A., Ries, J. & Lvovsky, A. I. Quantum scissors: teleportation of single-mode optical states by means of a nonlocal single photon. Preprint at http://arXiv.org/quant-ph/0208066 (2002).

References to web-only journals should give authors, article title and journal name as above, followed by URL in full - or DOI if known - and the year of publication in parentheses.

References to websites should give authors if known, title of cited page, URL in full, and year of posting in parentheses.

End notes are brief and follow the Methods (or Methods References, if any).

Acknowledgements should be brief, and should not include thanks to anonymous referees and editors, inessential words, or effusive comments. A person can be thanked for assistance, not “excellent” assistance, or for comments, not “insightful” comments, for example. Acknowledgements can contain grant and contribution numbers.

Author Contributions: Authors are required to include a statement to specify the contributions of each co-author. The statement can be up to several sentences long, describing the tasks of individual authors referred to by their initials. See the authorship policy page for further explanation and examples.

Competing interests  statement.

Additional Information: Authors should include a set of statements at the end of the paper, in the following order:

Papers containing Supplementary Information contain the statement: “Supplementary Information is available for this paper.”

A sentence reading "Correspondence and requests for materials should be addressed to XX.” Nature expects this identified author to respond to readers’ enquiries and requests for materials, and to coordinate the handling of any other matters arising from the published contribution, including corrections complaints. The author named as corresponding author is not necessarily the senior author, and publication of this author’s name does not imply seniority. Authors may include more than one e-mail address if essential, in which event Nature will communicate with the first-listed address for any post-publication matters, and expect that author to coordinate with the other co-authors.

Peer review information includes the names of reviewers who agree to be cited and is completed by Nature staff during proofing.

A sentence reading “Reprints and permissions information is available at www.nature.com/reprints.”

Life sciences and behavioural & social sciences reporting guidelines

To improve the transparency of reporting and the reproducibility of published results, authors of life sciences and behavioural & social sciences Articles must provide a completed Reporting Summary that will be made available to editors and reviewers during manuscript assessment. The Reporting Summary will be published with all accepted manuscripts.

Please note: because of the advanced features used in these forms, you must use Adobe Reader to open the documents and fill them out.

Guidance and resources related to the use and reporting of statistics are available here .

Tables should each be presented on a separate page, portrait (not landscape) orientation, and upright on the page, not sideways.

Tables have a short, one-line title in bold text. Tables should be as small as possible. Bear in mind the size of a Nature page as a limiting factor when compiling a table.

Symbols and abbreviations are defined immediately below the table, followed by essential descriptive material as briefly as possible, all in double-spaced text.

Standard table formats are available for submissions of cryo-EM , NMR and X-ray crystallography data . Authors providing these data must use these standard tables and include them as Extended Data.

Figure legends

For initial submissions, we encourage authors to present the manuscript text and figures together in a single Word doc or PDF file, and for each figure legend to be presented together with its figure. However, when preparing the final paper to be accepted, we require figure legends to be listed one after the other, as part of the text document, separate from the figure files, and after the main reference list.

Each figure legend should begin with a brief title for the whole figure and continue with a short description of each panel and the symbols used. If the paper contains a Methods section, legends should not contain any details of methods. Legends should be fewer than 300 words each.

All error bars and statistics must be defined in the figure legend, as discussed above.

Nature requires figures in electronic format. Please ensure that all digital images comply with the Nature journals’ policy on image integrity .

Figures should be as small and simple as is compatible with clarity. The goal is for figures to be comprehensible to readers in other or related disciplines, and to assist their understanding of the paper. Unnecessary figures and parts (panels) of figures should be avoided: data presented in small tables or histograms, for instance, can generally be stated briefly in the text instead. Avoid unnecessary complexity, colouring and excessive detail.

Figures should not contain more than one panel unless the parts are logically connected; each panel of a multipart figure should be sized so that the whole figure can be reduced by the same amount and reproduced on the printed page at the smallest size at which essential details are visible. For guidance, Nature ’s standard figure sizes are 90 mm (single column) and 180 mm (double column) and the full depth of the page is 170 mm.

Amino-acid sequences should be printed in Courier (or other monospaced) font using the one-letter code in lines of 50 or 100 characters.

Authors describing chemical structures should use the Nature Research Chemical Structures style guide .

Some brief guidance for figure preparation:

Lettering in figures (labelling of axes and so on) should be in lower-case type, with the first letter capitalized and no full stop.

Units should have a single space between the number and the unit, and follow SI nomenclature or the nomenclature common to a particular field. Thousands should be separated by commas (1,000). Unusual units or abbreviations are defined in the legend.

Scale bars should be used rather than magnification factors.

Layering type directly over shaded or textured areas and using reversed type (white lettering on a coloured background) should be avoided where possible.

Where possible, text, including keys to symbols, should be provided in the legend rather than on the figure itself.

Figure quality

At initial submission, figures should be at good enough quality to be assessed by referees, preferably incorporated into the manuscript text in a single Word doc or PDF, although figures can be supplied separately as JPEGs if authors are unable to include them with the text. Authors are advised to follow the initial and revised submissions guidelines with respect to sizing, resolution and labelling.

Please note that print-publication quality figures are large and it is not helpful to upload them at the submission stage. Authors will be asked for high-quality figures when they are asked to submit the final version of their article for publication.At that stage, please prepare figures according to these guidelines .

Third party rights

Nature discourages the use or adaptation of previously published display items (for example, figures, tables, images, videos or text boxes). However, we recognize that to illustrate some concepts the use of published data is required and the reuse of previously published display items may be necessary. Please note that in these instances we might not be able to obtain the necessary rights for some images to be reused (as is, or adapted versions) in our articles. In such cases, we will contact you to discuss the sourcing of alternative material.

Figure costs

In order to help cover some of the additional cost of four-colour reproduction, Nature Portfolio charges our authors a fee for the printing of their colour figures. Please contact our offices for exact pricing and details. Inability to pay this charge will not prevent publication of colour figures judged essential by the editors, but this must be agreed with the editor prior to acceptance.

Production-quality figures

When a manuscript is accepted in principle for publication, the editor will ask for high-resolution figures. Do not submit publication-quality figures until asked to do so by an editor. At that stage, please prepare figures according to these guidelines .

Extended Data

Extended Data figures and tables are online-only (appearing in the online PDF and full-text HTML version of the paper), peer-reviewed display items that provide essential background to the Article but are not included in the printed version of the paper due to space constraints or being of interest only to a few specialists. A maximum of ten Extended Data display items (figures and tables) is typically permitted. See Composition of a Nature research paper .

Extended Data tables should be formatted along similar lines to tables appearing in print (see section 5.7) but the main body (excluding title and legend, which should be included at the end of the Word file) should be submitted separately as an image rather than as an editable format in Word, as Extended Data tables are not edited by Nature’s subediting department. Small tables may also be included as sub-panels within Extended Data figures. See Extended Data Formatting Guide .

Extended Data figures should be prepared along slightly different guidelines compared to figures appearing in print, and may be multi-panelled as long as they fit to size rules (see Extended Data Formatting Guide ). Extended Data figures are not edited or styled by Nature’s art department; for this reason, authors are requested to follow Nature style as closely as possible when preparing these figures. The legends for Extended Data figures should be prepared as for print figures and should be listed one after the other at the end of the Word file.

If space allows, Nature encourages authors to include a simple schematic, as a panel in an Extended Data figure, that summarizes the main finding of the paper, where appropriate (for example, to assist understanding of complex detail in cell, structural and molecular biology disciplines).

If a manuscript has Extended Data figures or tables, authors are asked to refer to discrete items at an appropriate place in the main text (for example, Extended Data Fig. 1 and Extended Data Table 1).

If further references are included in the Extended Data tables and Extended Data figure legends, the numbering should continue from the end of the last reference number in the main paper (or from the last reference number in the additional Methods section if present) and the list should be added to the end of the list accompanying the additional Methods section, if present, or added below the Extended Data legends if no additional Methods section is present.

Supplementary Information

Supplementary Information (SI) is online-only, peer-reviewed material that is essential background to the Article (for example, large data sets, methods, calculations), but which is too large or impractical, or of interest only to a few specialists, to justify inclusion in the printed version of the paper. See the Supplementary Information page for further details.

Supplementary Information should not contain figures (any figures additional to those appearing in print should be formatted as Extended Data figures). Tables may be included in Supplementary Information, but only if they are unsuitable for formatting as Extended Data tables (for example, tables containing large data sets or raw data that are best suited to Excel files).

If a manuscript has accompanying SI, either at submission or in response to an editor’s letter that requests it, authors are asked to refer to discrete items of the SI (for example, videos, tables) at an appropriate point in the main manuscript.

Chemical structures and characterization of chemical materials

For guidelines describing Nature ’s standards for experimental methods and the characterization of new compounds, please see the information sheet on the characterization of chemical materials .

We aim to produce chemical structures in a consistent format throughout our articles. Please use the Nature Portfolio Chemical Structures Guide and ChemDraw template to ensure that you prepare your figures in a format that will require minimal changes by our art and production teams. Submit final files at 100% as .cdx files.

what is scientific paper format

WRITING A SCIENTIFIC RESEARCH ARTICLE | Format for the paper | Edit your paper! | Useful books | FORMAT FOR THE PAPER Scientific research articles provide a method for scientists to communicate with other scientists about the results of their research. A standard format is used for these articles, in which the author presents the research in an orderly, logical manner. This doesn't necessarily reflect the order in which you did or thought about the work.  This format is: | Title | Authors | Introduction | Materials and Methods | Results (with Tables and Figures ) | Discussion | Acknowledgments | Literature Cited | TITLE Make your title specific enough to describe the contents of the paper, but not so technical that only specialists will understand. The title should be appropriate for the intended audience. The title usually describes the subject matter of the article: Effect of Smoking on Academic Performance" Sometimes a title that summarizes the results is more effective: Students Who Smoke Get Lower Grades" AUTHORS 1. The person who did the work and wrote the paper is generally listed as the first author of a research paper. 2. For published articles, other people who made substantial contributions to the work are also listed as authors. Ask your mentor's permission before including his/her name as co-author. ABSTRACT 1. An abstract, or summary, is published together with a research article, giving the reader a "preview" of what's to come. Such abstracts may also be published separately in bibliographical sources, such as Biologic al Abstracts. They allow other scientists to quickly scan the large scientific literature, and decide which articles they want to read in depth. The abstract should be a little less technical than the article itself; you don't want to dissuade your potent ial audience from reading your paper. 2. Your abstract should be one paragraph, of 100-250 words, which summarizes the purpose, methods, results and conclusions of the paper. 3. It is not easy to include all this information in just a few words. Start by writing a summary that includes whatever you think is important, and then gradually prune it down to size by removing unnecessary words, while still retaini ng the necessary concepts. 3. Don't use abbreviations or citations in the abstract. It should be able to stand alone without any footnotes. INTRODUCTION What question did you ask in your experiment? Why is it interesting? The introduction summarizes the relevant literature so that the reader will understand why you were interested in the question you asked. One to fo ur paragraphs should be enough. End with a sentence explaining the specific question you asked in this experiment. MATERIALS AND METHODS 1. How did you answer this question? There should be enough information here to allow another scientist to repeat your experiment. Look at other papers that have been published in your field to get some idea of what is included in this section. 2. If you had a complicated protocol, it may helpful to include a diagram, table or flowchart to explain the methods you used. 3. Do not put results in this section. You may, however, include preliminary results that were used to design the main experiment that you are reporting on. ("In a preliminary study, I observed the owls for one week, and found that 73 % of their locomotor activity occurred during the night, and so I conducted all subsequent experiments between 11 pm and 6 am.") 4. Mention relevant ethical considerations. If you used human subjects, did they consent to participate. If you used animals, what measures did you take to minimize pain? RESULTS 1. This is where you present the results you've gotten. Use graphs and tables if appropriate, but also summarize your main findings in the text. Do NOT discuss the results or speculate as to why something happened; t hat goes in th e Discussion. 2. You don't necessarily have to include all the data you've gotten during the semester. This isn't a diary. 3. Use appropriate methods of showing data. Don't try to manipulate the data to make it look like you did more than you actually did. "The drug cured 1/3 of the infected mice, another 1/3 were not affected, and the third mouse got away." TABLES AND GRAPHS 1. If you present your data in a table or graph, include a title describing what's in the table ("Enzyme activity at various temperatures", not "My results".) For graphs, you should also label the x and y axes. 2. Don't use a table or graph just to be "fancy". If you can summarize the information in one sentence, then a table or graph is not necessary. DISCUSSION 1. Highlight the most significant results, but don't just repeat what you've written in the Results section. How do these results relate to the original question? Do the data support your hypothesis? Are your results consistent with what other investigators have reported? If your results were unexpected, try to explain why. Is there another way to interpret your results? What further research would be necessary to answer the questions raised by your results? How do y our results fit into the big picture? 2. End with a one-sentence summary of your conclusion, emphasizing why it is relevant. ACKNOWLEDGMENTS This section is optional. You can thank those who either helped with the experiments, or made other important contributions, such as discussing the protocol, commenting on the manuscript, or buying you pizza. REFERENCES (LITERATURE CITED) There are several possible ways to organize this section. Here is one commonly used way: 1. In the text, cite the literature in the appropriate places: Scarlet (1990) thought that the gene was present only in yeast, but it has since been identified in the platypus (Indigo and Mauve, 1994) and wombat (Magenta, et al., 1995). 2. In the References section list citations in alphabetical order. Indigo, A. C., and Mauve, B. E. 1994. Queer place for qwerty: gene isolation from the platypus. Science 275, 1213-1214. Magenta, S. T., Sepia, X., and Turquoise, U. 1995. Wombat genetics. In: Widiculous Wombats, Violet, Q., ed. New York: Columbia University Press. p 123-145. Scarlet, S.L. 1990. Isolation of qwerty gene from S. cerevisae. Journal of Unusual Results 36, 26-31.   EDIT YOUR PAPER!!! "In my writing, I average about ten pages a day. Unfortunately, they're all the same page." Michael Alley, The Craft of Scientific Writing A major part of any writing assignment consists of re-writing. Write accurately Scientific writing must be accurate. Although writing instructors may tell you not to use the same word twice in a sentence, it's okay for scientific writing, which must be accurate. (A student who tried not to repeat the word "hamster" produced this confusing sentence: "When I put the hamster in a cage with the other animals, the little mammals began to play.") Make sure you say what you mean. Instead of: The rats were injected with the drug. (sounds like a syringe was filled with drug and ground-up rats and both were injected together) Write: I injected the drug into the rat.
  • Be careful with commonly confused words:
Temperature has an effect on the reaction. Temperature affects the reaction.
I used solutions in various concentrations. (The solutions were 5 mg/ml, 10 mg/ml, and 15 mg/ml) I used solutions in varying concentrations. (The concentrations I used changed; sometimes they were 5 mg/ml, other times they were 15 mg/ml.)
 Less food (can't count numbers of food) Fewer animals (can count numbers of animals)
A large amount of food (can't count them) A large number of animals (can count them)
The erythrocytes, which are in the blood, contain hemoglobin. The erythrocytes that are in the blood contain hemoglobin. (Wrong. This sentence implies that there are erythrocytes elsewhere that don't contain hemoglobin.)

Write clearly

1. Write at a level that's appropriate for your audience.

"Like a pigeon, something to admire as long as it isn't over your head." Anonymous

 2. Use the active voice. It's clearer and more concise than the passive voice.

 Instead of: An increased appetite was manifested by the rats and an increase in body weight was measured. Write: The rats ate more and gained weight.

 3. Use the first person.

 Instead of: It is thought Write: I think
 Instead of: The samples were analyzed Write: I analyzed the samples

 4. Avoid dangling participles.

 "After incubating at 30 degrees C, we examined the petri plates." (You must've been pretty warm in there.)

  Write succinctly

 1. Use verbs instead of abstract nouns

 Instead of: take into consideration Write: consider

 2. Use strong verbs instead of "to be"

 Instead of: The enzyme was found to be the active agent in catalyzing... Write: The enzyme catalyzed...

 3. Use short words.

Instead of: Write: possess have sufficient enough utilize use demonstrate show assistance help terminate end

4. Use concise terms.

 Instead of: Write: prior to before due to the fact that because in a considerable number of cases often the vast majority of most during the time that when in close proximity to near it has long been known that I'm too lazy to look up the reference

5. Use short sentences. A sentence made of more than 40 words should probably be rewritten as two sentences.

 "The conjunction 'and' commonly serves to indicate that the writer's mind still functions even when no signs of the phenomenon are noticeable." Rudolf Virchow, 1928

  

Check your grammar, spelling and punctuation

1. Use a spellchecker, but be aware that they don't catch all mistakes.

 "When we consider the animal as a hole,..." Student's paper

 2. Your spellchecker may not recognize scientific terms. For the correct spelling, try Biotech's Life Science Dictionary or one of the technical dictionaries on the reference shelf in the Biology or Health Sciences libraries.

 3. Don't, use, unnecessary, commas.

 4. Proofread carefully to see if you any words out.

The Effects of Social Media on Mental Health

University of XYZ

This study examines the relationship between social media use and mental health among college students. Data was collected through a survey of 500 students at the University of XYZ. Results suggest that social media use is significantly related to symptoms of depression and anxiety, and that the negative effects of social media are greater among frequent users.

Social media has become an increasingly important aspect of modern life, especially among young adults. While social media can have many positive effects, such as connecting people across distances and sharing information, there is growing concern about its impact on mental health. This study aims to examine the relationship between social media use and mental health among college students.

Participants: Participants were 500 college students at the University of XYZ, recruited through online advertisements and flyers posted on campus. Participants ranged in age from 18 to 25, with a mean age of 20.5 years. The sample was 60% female, 40% male, and 5% identified as non-binary or gender non-conforming.

Data was collected through an online survey administered through Qualtrics. The survey consisted of several measures, including the Patient Health Questionnaire-9 (PHQ-9) for depression symptoms, the Generalized Anxiety Disorder-7 (GAD-7) for anxiety symptoms, and questions about social media use.

Procedure :

Participants were asked to complete the online survey at their convenience. The survey took approximately 20-30 minutes to complete. Data was analyzed using descriptive statistics, correlations, and multiple regression analysis.

Results indicated that social media use was significantly related to symptoms of depression (r = .32, p < .001) and anxiety (r = .29, p < .001). Regression analysis indicated that frequency of social media use was a significant predictor of both depression symptoms (β = .24, p < .001) and anxiety symptoms (β = .20, p < .001), even when controlling for age, gender, and other relevant factors.

The results of this study suggest that social media use is associated with symptoms of depression and anxiety among college students. The negative effects of social media are greater among frequent users. These findings have important implications for mental health professionals and educators, who should consider addressing the potential negative effects of social media use in their work with young adults.

References :

References should be listed in alphabetical order according to the author’s last name. For example:

  • Chou, H. T. G., & Edge, N. (2012). “They are happier and having better lives than I am”: The impact of using Facebook on perceptions of others’ lives. Cyberpsychology, Behavior, and Social Networking, 15(2), 117-121.

Title: The Impact of Video Games on Aggression Levels

Video games have become a popular form of entertainment among people of all ages. However, the impact of video games on aggression levels has been a subject of debate among scholars and researchers. While some argue that video games promote aggression and violent behavior, others argue that there is no clear link between video games and aggression levels. This research paper aims to explore the impact of video games on aggression levels among young adults.

Background:

The debate on the impact of video games on aggression levels has been ongoing for several years. According to the American Psychological Association, exposure to violent media, including video games, can increase aggression levels in children and adolescents. However, some researchers argue that there is no clear evidence to support this claim. Several studies have been conducted to examine the impact of video games on aggression levels, but the results have been mixed.

Methodology:

This research paper used a quantitative research approach to examine the impact of video games on aggression levels among young adults. A sample of 100 young adults between the ages of 18 and 25 was selected for the study. The participants were asked to complete a questionnaire that measured their aggression levels and their video game habits.

The results of the study showed that there was a significant correlation between video game habits and aggression levels among young adults. The participants who reported playing violent video games for more than 5 hours per week had higher aggression levels than those who played less than 5 hours per week. The study also found that male participants were more likely to play violent video games and had higher aggression levels than female participants.

The findings of this study support the claim that video games can increase aggression levels among young adults. However, it is important to note that the study only examined the impact of video games on aggression levels and did not take into account other factors that may contribute to aggressive behavior. It is also important to note that not all video games promote violence and aggression, and some games may have a positive impact on cognitive and social skills.

Conclusion :

In conclusion, this research paper provides evidence to support the claim that video games can increase aggression levels among young adults. However, it is important to conduct further research to examine the impact of video games on other aspects of behavior and to explore the potential benefits of video games. Parents and educators should be aware of the potential impact of video games on aggression levels and should encourage young adults to engage in a variety of activities that promote cognitive and social skills.

Title: The Impact of Social Media on Political Engagement

Name: John Smith

Class: POLS 101

Professor: Dr. Jane Doe

Date: April 8, 2023

I. Introduction:

Social media has become an integral part of our daily lives. People use social media platforms like Facebook, Twitter, and Instagram to connect with friends and family, share their opinions, and stay informed about current events. With the rise of social media, there has been a growing interest in understanding its impact on various aspects of society, including political engagement. In this paper, I will examine the relationship between social media use and political engagement, specifically focusing on how social media influences political participation and political attitudes.

II. Literature Review:

There is a growing body of literature on the impact of social media on political engagement. Some scholars argue that social media has a positive effect on political participation by providing new channels for political communication and mobilization (Delli Carpini & Keeter, 1996; Putnam, 2000). Others, however, suggest that social media can have a negative impact on political engagement by creating filter bubbles that reinforce existing beliefs and discourage political dialogue (Pariser, 2011; Sunstein, 2001).

III. Methodology:

To examine the relationship between social media use and political engagement, I conducted a survey of 500 college students. The survey included questions about social media use, political participation, and political attitudes. The data was analyzed using descriptive statistics and regression analysis.

Iv. Results:

The results of the survey indicate that social media use is positively associated with political participation. Specifically, respondents who reported using social media to discuss politics were more likely to have participated in a political campaign, attended a political rally, or contacted a political representative. Additionally, social media use was found to be associated with more positive attitudes towards political engagement, such as increased trust in government and belief in the effectiveness of political action.

V. Conclusion:

The findings of this study suggest that social media has a positive impact on political engagement, by providing new opportunities for political communication and mobilization. However, there is also a need for caution, as social media can also create filter bubbles that reinforce existing beliefs and discourage political dialogue. Future research should continue to explore the complex relationship between social media and political engagement, and develop strategies to harness the potential benefits of social media while mitigating its potential negative effects.

Scientific paper structure: get started with this quick and easy guide

scientific paper structure is an hourglass

Why the scientific paper structure? It mimics the research process!

Science can be daunting enough – the scientific paper structure doesn’t have to be, too!

In fact, the structure of a scientific paper is meant to be anything but daunting, as it is designed to mimic how science actually progresses.

Don’t believe me? Think about this –

–>Research usually starts with a topic ( title ) .

–>Then, you need to study the s tate of the field around that topic, identify key gaps to address, and form a hypotheses ( introduction ).

–>Next, you gather the tools and equipment you need to do that research ( materials ) and perform experiments ( methods ).

–>After that, you report the results of those experiments ( results ) and see how those results affect the field and integrate back into it ( discussion ).

Helpfully, that is also exactly how your scientific paper is structured.

A scientific research paper is typically ordered:

  • Introduction
  • Materials and Methods
  • Discussion/Conclusions

*Note: This page is going to walk you though the scientific paper structure. If you want info on writing each of these sections, please see my comprehensive page on writing your scientific manuscript !

Scientific paper structure: IMRAD and scope

In more technical terms, the scientific paper is usually structured in what we call the IMRAD format, standing for “ I ntroduction, M ethods, R esults A nd D iscussion.”

An IMRAD-based paper includes:

I ntroduction

  •    Why did you do this research?
  •   What was the original hypothesis?
  •   When, where, and how did you do this research?
  •   What materials or subjects were involved?
  •   What did you discover?
  •   Was the tested hypothesis true?

a nd D iscussion

  •   What do your results mean?
  •   How does this fit within the field?
  •   What are the future  prospectives ?

Besides mimicking the research process, the structure of an IMRAD paper is also helpful for the reader in terms of the the scope of the paper and is designed to draw them in and then show them how your work matters.

What is the scope?

The scope indicates how broadly or narrowly the writing is focused. If the writing in a certain section has a broad scope , it is designed to be accessible to a broad audience . If the writing in a section has a narrow scope , it is designed to be the most focused on your specific work – which is directly accessible to a much smaller audience .

To show you what I mean, I made this diagram that shows how the scope of an IMRAD paper changes from beginning to end:

scientific paper structure is an hourglass

Note how the scope of a scientific paper makes an hourglass shape.

This makes sense, as the important results of your paper are the narrowest in scope. Because this scope is so narrow, it is not widely known, so it would not be accessible to a reader unless it was bookended with information that is much broader in scope, or information that is more well known and understood. This is how you teach the reader what they need to know to understand your work and give them the tools to place your work in context.

Therefore, the introduction of our paper is going to start at the very broadest scope, first introducing the reader to our field in general and then to our research more specifically. In this way, we will start at a very broad scope and slowly narrow into the results – which represent the narrowest scope in our paper.

Scientific paper structure: Key parts

1. title and abstract: attract the reader’s attention.

A scientific paper usually starts with two key parts that help attract a reader’s attention to your work: the title and abstract.

These parts are designed to essentially be the advertisement for your paper.

This means they need to be informative enough about the content of the paper to attract the right readers to your paper, and they also need to be written in a way that is interesting enough to attract those who might not otherwise find your paper.

Also note, basically any reader who gets to the paper body will have read your title and then abstract. By making sure your title and abstract are as attractive as possible, you can get more readers interested in also reading the paper body!

Circles indicating relative views of paper - title gets the most followed by abstract and then paper body

The title contains the key words of the paper, and tries to organize them in a way that lets the reader know what kind of study you conducted and roughly what you accomplished in that paper.

For all of my advice on writing your title, go here .

The abstract is also written to draw attention to your papers, so you want to structure it in a similar hourglass shape as the paper body.

The abstract should

  • start with a broad problem that is relatable to the average reader of that journal
  • indicate how your proposed to solve that problem ( hypothesis or research objectives )
  • give a few lines about what you did in the paper, including key methods and results
  • end with a statement about why your work is important and why it deserves to be published .

This is a lot to ask of a normally 250 word abstract!

Don’t worry – I show you exactly how to do this. For all of my advice on writing your abstract, go here.

2. Introduction: Introduce the reader to your work

After the reader has opened your paper, they need to be introduced to not only your work, but why it matters. This is where the introduction comes in!

Most scientists are good at introducing the literature surrounding their field – which is a big part of the introduction – but struggle to convey the importance or necessity of their work.

Part of this is because many people fail to see the importance of introducing the entire field to the reader to show why it is important to do research in that field.

Therefore, the introduction should start with a very wide overview and include a paragraph at the beginning that introduces the entire field to the reader.

Hourglass shows scope of introduction of scientific research paper

Paragraphs of your introduction

Paragraph 1. The first paragraph of the introduction should answer the question – “Why does my research field exist?” 

Importantly – this paragraph should include a very clear statement of a gap that still exists in the world that your field of research seeks to fill .

Paragraphs 2-3 . Next, it is important to introduce to the reader why your research project exists, which involves the traditional review of relevant literature that most scientists are comfortable writing. These next 1-2 paragraphs should answer the question – “Why does the research in this paper exist?”

Importantly – these paragraphs should include a very clear statement of a gap that still exists in the field that your specific research project seeks to fil l .

Paragraph 4 . The last paragraph of the introduction should give the reader an overview of what to expect in this paper. It should include a typical “Here, we did…” sentence as well as a very short summary of key methods or results.

But we aren’t done yet…

This final paragraph should also end on a sentence that answers the question – “Why does this work matter and deserve to be published?”

The most impactful introductions all end with this forward-thinking statement that helps the reader place the product of your work into context. Don’t underestimate this sentence – getting the “why” into your reader’s head from the beginning can do wonders for their ability to grasp the importance of your work.

For all of my advice on how to write your introduction, go here !

3. Materials and Methods: Tell the reader what you did and how you did it

After setting up why your research projected needed to exist and what you hoped to accomplish, it is time to tell the reader what you did and how you did it.

In terms of text, this section on your materials and methods is the narrowest in scope of all of you paper, as it related to your project alone.

Hourglass shows scope of materials and methods of scientific research paper

In this section, you need provide enough detail that your work could be repeated.

Tell your reader:

  • what materials you used and where you bought them
  • what equipment you used
  • what protocols you followed
  • how you did each experiment
  • how you analyzed your results
  • how you calculated statistics

If you want your work to be considered robust, others need to be able to repeat it.

At this point, your paper should convey what another lab would need to know to copy what you did in this work.

4. Results: Show the reader what you saw

The final section of the narrow scope in your paper is your results, where you tell the reader what you saw in your experiments.

Hourglass shows scope of results of scientific research paper

These paragraphs tell the story of your paper, and should be designed as such.

For the best readability of this section, the results should be structured such that each paragraph :

  • represents one experiment or group of related experiments
  • begins with a topic sentence that tells the reader what you did in that paragraph and why
  • end with a summary statement (1/2 – 1 sentence) telling the reader the main take-home point of that paragraph

The results section should not :

  • Provide extra introductory info only when it is needed to understand the following work and does not apply to the entire paper
  • Provide only enough here such that the reader understands what experiments were done and what the controls were .
  • The reader should not be able to reproduce your experiments from the details in this section
  • Provide only enough for the reader to understand the rest of the paper plus the paragraph-ending summary statement .

For all of my advice on how to write your results, go here !

5. Discussion: Walk the reader through what your results mean and how they affect the field

At the end of the paper, the reader needs to know what your results mean and how they integrate in the field – it is the only way to understand the importance and impact of your work!

For this, the discussion is the opposite of the introduction – it funnels the reader OUT of your work, building on your results to connect your work to the field and society as a whole.

Hourglass shows scope of discussion of scientific research paper

Paragraphs of your discussion

Paragraph 1. The first paragraph briefly summarizes the main results of the paper and directly shows how they address the gap in the field  that was mentioned in the introduction.

Paragraphs 2-4. These middle paragraphs discuss your results. For each paragraph, take one key result and:

  • analyze it – what does it mean?
  • relate it to the field – how does it tie into other work in the field?
  • relate it to the gap – how does it help fill the gap that you discussed in the introduction?
  • speculate beyond the current limits of the field – what new research questions do these results bring up?
  • f uture directions – how can this research be expanded on in the future?

Final paragraph – the conclusion.   The conclusion should never be a summary of the paper – this misses a great opportunity to highlight the importance and impact of your work, and leave the reader with a forward-thinking outlook.

Hourglass shows broad scope of conclusion of scientific research paper

The conclusion does a disservice to your paper if it doesn’t highlight why your work deserves to be published. Make sure it answers:

  • Why should scientists be excited about this work?
  • Why should non-scientists be excited?

For all of my advice on how to write your discussion, go here !

Scientific paper structure: Putting it all together and writing

Now after seeing how a scientific paper is structured and why, you might still be struggling to write the paper…don’t worry, this is completely normal!

Just because we know the structure we need to strive for, it still isn’t easy to translate our work into a paper. This is because the way a paper is structured is designed to help the reader through the process, but it is not necessarily the easiest ordering for writing a paper.

Introduction.

  • Writing Effectively
  • Where to Publish?
  • Capstone Resources

Different sections are needed in different types of scientific papers (lab reports, literature reviews, systematic reviews, methods papers, research papers, etc.). Projects that overlap with the social sciences or humanities may have different requirements. Generally, however, you'll need to include:

INTRODUCTION (Background)

METHODS SECTION (Materials and Methods)

What is a title

Titles have two functions: to identify the main topic or the message of the paper and to attract readers.

The title will be read by many people. Only a few will read the entire paper, therefore all words in the title should be chosen with care. Too short a title is not helpful to the potential reader. Too long a title can sometimes be even less meaningful. Remember a title is not an abstract. Neither is a title a sentence.

What makes a good title?

A good title is accurate, complete, and specific. Imagine searching for your paper in PubMed. What words would you use?

  • Use the fewest possible words that describe the contents of the paper.
  • Avoid waste words like "Studies on", or "Investigations on".
  • Use specific terms rather than general.
  • Use the same key terms in the title as the paper.
  • Watch your word order and syntax.

The abstract is a miniature version of your paper. It should present the main story and a few essential details of the paper for readers who only look at the abstract and should serve as a clear preview for readers who read your whole paper. They are usually short (250 words or less).

The goal is to communicate:

  •  What was done?
  •  Why was it done?
  •  How was it done?
  •  What was found?

A good abstract is specific and selective. Try summarizing each of the sections of your paper in a sentence two. Do the abstract last, so you know exactly what you want to write.

  • Use 1 or more well developed paragraphs.
  • Use introduction/body/conclusion structure.
  • Present purpose, results, conclusions and recommendations in that order.
  • Make it understandable to a wide audience.

How to read a scientific paper: a step-by-step guide

tips how to read an academic paper

Scientific paper format

How to read a scientific paper in 3 steps, step 1: identify your motivations for reading a scientific paper, step 2: use selective reading to gain a high-level understanding of the scientific paper, step 3: read straight through to achieve a deep understanding of a scientific paper, other sources to help you read a scientific paper, frequently asked questions about reading a scientific paper efficiently, related articles.

A scientific paper is a complex document. Scientific papers are divided into multiple sections and frequently contain jargon and long sentences that make reading difficult. The process of reading a scientific paper to obtain information can often feel overwhelming for an early career researcher.

But the good news is that you can acquire the skill of efficiently reading a scientific paper, and you can learn how to painlessly obtain the information you need.

In this guide, we show you how to read a scientific paper step-by-step. You will learn:

  • The scientific paper format
  • How to identify your reasons for reading a scientific paper
  • How to skim a paper
  • How to achieve a deep understanding of a paper.

Using these steps for reading a scientific paper will help you:

  • Obtain information efficiently
  • Retain knowledge more effectively
  • Allocate sufficient time to your reading task.

The steps below are the result of research into how scientists read scientific papers and our own experiences as scientists.

Firstly, how is a scientific paper structured?

The main sections are Abstract, Introduction, Methods, Results, and Discussion. In the table below, we describe the purpose of each component of a scientific paper.

Because the structured format of a scientific paper makes it easy to find the information you need, a common technique for reading a scientific paper is to cherry-pick sections and jump around the paper.

In a YouTube video, Dr. Amina Yonis shows this nonlinear practice for reading a scientific paper. She justifies her technique by stating that “By reading research papers like this, you are enabling yourself to have a disciplined approach, and it prevents yourself from drowning in the details before you even get a bird’s-eye view”.

Selective reading is a skill that can help you read faster and engage with the material presented. In his article on active vs. passive reading of scientific papers, cell biologist Tung-Tien Sun defines active reading as "reading with questions in mind" , searching for the answers, and focusing on the parts of the paper that answer your questions.

Therefore, reading a scientific paper from start to finish isn't always necessary to understand it. How you read the paper depends on what you need to learn. For example, oceanographer Ken Hughes suggests that you may read a scientific paper to gain awareness of a theory or field, or you may read to actively solve a problem in your research.

3 steps for reading a scientific paper.

To successfully read a scientific paper, we advise using three strategies:

  • Identify your motivations for reading a scientific paper
  • Use selective reading to gain a high-level understanding of the scientific paper
  • Read straight through to achieve a deep understanding of a scientific paper .

All 3 steps require you to think critically and have questions in mind.

Before you sit down to read a scientific paper, ask yourself these three questions:

  • Why do I need to read this paper?
  • What information am I looking for?
  • Where in the paper am I most likely to find the information I need?

Is it background reading or a literature review for a research project you are currently working on? Are you getting into a new field of research? Do you wish to compare your results with the ones presented in the paper? Are you following an author’s work, and need to keep up-to-date on their current research? Are you keeping tabs on emerging methods in your field?

All of these intentions require a different reading approach.

For example, if you are getting into a new research field, to obtain background information and seminal references, you will be very interested in the introduction. You will also want to read the discussion, to understand the wider context in which the findings lie.

If you are following an author’s work, a cursory skim may be all that is required to understand how the paper lies within their overall research program.

If you are primarily interested in the study design and techniques the authors have used, then you will spend the most time reading and understanding the methods section of the paper.

Other times you need to read a paper that you may discuss in your own research, for example, to compare or contrast the work in it with yours, or to motivate a discussion point for future applications of your own work.

And if your aim is to extend the work presented in a paper, and consequently the study will form the starting point for your work, you will need to understand the paper deeply.

Knowing why you want to read the paper facilitates how you will read the paper. Depending on your needs, your approach may take the form of a surface-level reading or a deep reading.

Knowing your motivations will also guide your navigation through the paper because you have already identified which sections are most likely to contain the information you need. Approaching reading a paper in this way saves you time and makes the task less daunting.

➡️ Learn more about how to write a literature review

Begin by gaining an overview of the paper by following these simple steps:

  • Read the title. What type of paper is it? Is it a journal article, a review, a methods paper, or a commentary?
  • Read the abstract . The abstract is a summary of the study. What is the study about? What question was addressed? What methods were used? What did the authors find, and what are the key findings? What do the authors think are the implications of the work? Reading the abstract immediately tells you whether you should invest the time to read the paper fully.
  • Look at the headings and subheadings, which describe the sections and subsections of the paper. The headings and subheadings outline the story of the paper.
  • Skim the introduction. An introduction has a clear structure. The first paragraph is background information on the topic. If you are new to the field, you will read this closely, whereas an expert in that field will skim this section. The second component defines the gap in knowledge that the paper aims to address. What is unknown, and what research is needed? What problem needs to be solved? Here, you should find the questions that will be addressed by the study, and the goal of the research. The final paragraph summarizes how the authors address their research question, for example, what hypothesis will be tested, and what predictions the authors make. As you read, make a note of key references. By the end of the introduction, you should understand the goal of the research.
  • Go to the results section, and study the figures and tables. These are the data—the meat of the study. Try to comprehend the data before reading the captions. After studying the data, read the captions. Do not expect to understand everything immediately. Remember, this is the result of many years of work. Make a note of what you do not understand. In your second reading, you will read more deeply.
  • Skim the discussion. There are three components. The first part of the discussion summarizes what the authors have found, and what they think the implications of the work are. The second part discusses some (usually not all!) limitations of the study, and the final part is a concluding statement.
  • Glance at the methods. Get a brief overview of the techniques used in the study. Depending on your reading goals, you may spend a lot of time on this section in subsequent readings, or a cursory reading may be sufficient.
  • Summarize what the paper is about—its key take-home message—in a sentence or two. Ask yourself if you have got the information you need.
  • List any terminology you may need to look up before reading the paper again.
  • Scan the reference list. Make a note of papers you may need to read for background information before delving further into the paper.

Congratulations, you have completed the first reading! You now have gained a high-level perspective of the study, which will be enough for many research purposes.

Now that you have an overview of the work and you have identified what information you want to obtain, you are ready to understand the paper on a deeper level. Deep understanding is achieved in the second and subsequent readings. Here is a step-by-step guide.

  • Active engagement with the material
  • Critical thinking
  • Creative thinking
  • Synthesis of information
  • Consolidation of information into memory.

Highlighting sentences helps you quickly scan the paper and be reminded of the key points, which is helpful when you return to the paper later.

Notes may include ideas, connections to other work, questions, comments, and references to follow up on. You can take notes in many ways:

  • Print out the paper, and write your notes in the margins.
  • Annotate the paper PDF from your desktop computer, or mobile device .
  • Use personal knowledge management software, like Notion , Obsidian, or Evernote, for note-taking. Notes are easy to find in a structured database and can be linked to each other.
  • Use reference management tools to take notes. Having your notes stored with the scientific papers you’ve read has the benefit of keeping all your ideas in one place. Some reference managers, like Paperpile, allow you to add notes to your papers, and highlight key sentences on PDFs .

Note-taking facilitates critical thinking and helps you evaluate the evidence that the authors present. Ask yourself questions like:

  • What new contribution has the study made to the literature?
  • How have the authors interpreted the results? (Remember, the authors have thought about their results more deeply than anybody else.)
  • What do I think the results mean?
  • Are the findings well-supported?
  • What factors might have affected the results, and have the authors addressed them?
  • Are there alternative explanations for the results?
  • What are the strengths and weaknesses of the study?
  • What are the broader implications of the study?
  • What should be done next?

Note-taking also encourages creative thinking . Ask yourself questions like:

  • What new ideas have arisen from reading the paper?
  • How does it connect with your work?
  • What connections to other papers can you make?
  • Write a summary of the paper in your own words. This is your attempt to integrate the new knowledge you have gained with what you already know from other sources and to consolidate that information into memory. You may find that you have to go back and re-read some sections to confirm some of the details.
  • Discuss the paper with others. You may find that even at this stage, there are still aspects of the paper that you are striving to understand. It is now a good time to reach out to others—peers in your program, your advisor, or even on social media. In their 10 simple rules for reading a scientific paper , Maureen Carey and coauthors suggest that participating in journal clubs, where you meet with peers to discuss interesting or important scientific papers, is a great way to clarify your understanding.
  • A scientific paper can be read over many days. According to research presented in the book " Make it Stick " by writer Peter Brown and psychology professors Henry Roediger and Mark McDaniel, "spaced practice" is more effective for retaining information than focusing on a single skill or subject until it is mastered. This involves breaking up learning into separate periods of training or studying. Applying this research to reading a scientific paper suggests that spacing out your reading by breaking the work into separate reading sessions can help you better commit the information in a paper to memory.

A dense journal article may need many readings to be understood fully. It is useful to remember that many scientific papers result from years of hard work, and the expectation of achieving a thorough understanding in one sitting must be modified accordingly. But, the process of reading a scientific paper will get easier and faster with experience.

➡️ How to (seriously) read a scientific paper

➡️ How to read a scientific paper efficiently and critically

The best way to read a scientific paper depends on your needs. Before reading the paper, identify your motivations for reading a scientific paper, and pinpoint the information you need. This will help you decide between skimming the paper and reading the paper more thoroughly.

Don’t read the paper from beginning to end. Instead, be aware of the scientific paper format. Take note of the information you need before starting to read the paper. Then skim the paper, jumping to the appropriate sections in the paper, to get the information you require.

It varies. Skimming a scientific paper may take anywhere between 15 minutes to one hour. Reading a scientific paper to obtain a deep understanding may take anywhere between 1 and 6 hours. It is not uncommon to have to read a dense paper in chunks over numerous days.

First, read the introduction to understand the main thesis and findings of the paper. Pay attention to the last paragraph of the introduction, where you can find a high-level summary of the methods and results. Next, skim the paper by jumping to the results and discussion. Then carefully read the paper from start to finish, taking notes as you read. You will need more than one reading to fully understand a dense research paper.

To read a scientific paper critically, be an active reader. Take notes, highlight important sentences, and write down questions as you read. Study the data. Take care to evaluate the evidence presented in the paper.

Title: gistembed: guided in-sample selection of training negatives for text embedding fine-tuning.

Abstract: Embedding models are integral to AI applications like semantic search, personalized recommendations, and retrieval augmented generation for LLMs, necessitating high-quality training data. However, the limited scalability of manual data curation prompts the need for automated methods to ensure data integrity. Traditional unsupervised triplet mining automates training data generation, crucial for embedding model training, yet inadvertently injects biases and noise, thereby degrading model performance. Addressing this, we introduce GISTEmbed, a novel strategy that enhances in-batch negative selection during contrastive training through a guide model. This approach departs from reliance on random sampling and equal utility assumption of batch negatives, significantly reducing noise from data quality issues and improving model fine-tuning. Benchmarked against the Massive Text Embedding Benchmark (MTEB), GISTEmbed showcases consistent performance improvements across various model sizes and achieves state-of-the-art results in select categories. This framework enables significant enhancements for smaller models by leveraging the capabilities of powerful yet resource-intensive large models. GISTEmbed can potentially revolutionize the creation of highly efficient, smaller models, democratizing access to advanced AI technologies. Making these technologies more accessible and cost-effective, especially for applications constrained by resources, significantly expands the impact and accessibility of state-of-the-art AI solutions across diverse sectors.
