Scientific Writing

Scientific Writing

Overview

Use this skill to draft and revise scientific manuscript prose. It is the paragraph-writing skill, not the front door for every paper-related task. When new literature claims or citation-dependent context are introduced, back them with literature search and citation verification; do not force a new search for pure style edits, source-faithful revisions, or user-supplied evidence.

Scientific writing is a process for communicating research with precision and clarity. Write manuscript sections using IMRAD structure, evidence-bounded claims, complete paragraphs, and applicable reporting-guideline language. Use neighboring skills for the paper plan, submission package, venue format, bibliography, citation support verdict, figures, diagrams, or LaTeX mechanics.

Critical Principle: Always write in full paragraphs with flowing prose. Never submit bullet points in the final manuscript. Use a two-stage process when drafting from notes: first create section outlines from the available evidence and any required lookup results, then convert those outlines into complete paragraphs.

When to Use This Skill

This skill should be used when:

• Writing or revising any section of a scientific manuscript (abstract, introduction, methods, results, discussion)
• Turning existing results, methods, figure notes, or reviewer-response facts into complete manuscript paragraphs
• Applying study-specific reporting-guideline wording inside manuscript prose (CONSORT for trials, STROBE for observational studies, PRISMA for reviews)
• Drafting abstracts that meet journal requirements (structured or unstructured)
• Improving writing clarity, conciseness, and precision
• Ensuring proper use of field-specific terminology and nomenclature
• Addressing reviewer comments and revising manuscripts

Do not use this skill as the primary route for:

• Whole-paper process planning, claim-evidence spines, section contracts, or figure/text synchronization; use paper-workflow-orchestrator.
• Reviewer-style critique, acceptance-risk diagnosis, or rebuttal assessment; use peer-review.
• Rubric-based quantitative scholarly scoring; use scholar-evaluation.
• Current-paper discovery, related-work synthesis, or single-paper evidence cards; use literature-review or research-lookup.
• Citation existence, DOI/PMID metadata, claim-support verdicts, BibTeX cleanup, or Zotero operations; use literature-and-citations.
• Venue formatting, LaTeX build state, or editable figure production; use the venue, LaTeX, or visualization skills.

Visual and Figure Routing

Do not generate figures just because a manuscript is scientific. Add or revise visuals only when the user asks for figures, the venue requires a graphical abstract, the existing paper has figure/table gaps, or a complex method, result, workflow, or comparison would be clearer as a visual.

Route visual work by deliverable:

• Use scientific-visualization for data-driven plots, multi-panel figures, palettes, uncertainty displays, and publication export QA.
• Use scientific-schematics, drawio-diagrams, d2-diagrams, or markdown-mermaid-writing for method, workflow, architecture, or concept diagrams when an editable or text-based figure is appropriate.
• Use presentation/poster skills when the requested output is a talk, group meeting deck, journal club, poster, or PPTX.

Before finalizing prose, check that every referenced figure/table has a clear claim, every caption is evidence-bounded, and no figure is presented as proof of a claim that the underlying data does not support.

Core Capabilities

1. Manuscript Structure and Organization

IMRAD Format: Guide papers through the standard Introduction, Methods, Results, And Discussion structure used across most scientific disciplines. This includes:

• Introduction: Establish research context, identify gaps, state objectives
• Methods: Detail study design, populations, procedures, and analysis approaches
• Results: Present findings objectively without interpretation
• Discussion: Interpret results, acknowledge limitations, propose future directions

For detailed guidance on IMRAD structure, refer to references/imrad_structure.md.

Alternative Structures: Support discipline-specific formats including:

• Review articles (narrative, systematic, scoping)
• Case reports and case series
• Meta-analyses and pooled analyses
• Theoretical/modeling papers
• Methods papers and protocols

2. Section-Specific Writing Guidance

Abstract Composition: Craft concise, standalone summaries (100-250 words) that capture the paper's purpose, methods, results, and conclusions. Support both structured abstracts (with labeled sections) and unstructured single-paragraph formats.

Introduction Development: Build compelling introductions that:

• Establish the research problem's importance
• Review relevant literature systematically
• Identify knowledge gaps or controversies
• State clear research questions or hypotheses
• Explain the study's novelty and significance

Methods Documentation: Ensure reproducibility through:

• Detailed participant/sample descriptions
• Clear procedural documentation
• Statistical methods with justification
• Equipment and materials specifications
• Ethical approval and consent statements

Results Presentation: Present findings with:

• Logical flow from primary to secondary outcomes
• Integration with figures and tables
• Statistical significance with effect sizes
• Objective reporting without interpretation

Discussion Construction: Synthesize findings by:

• Relating results to research questions
• Comparing with existing literature
• Acknowledging limitations honestly
• Proposing mechanistic explanations
• Suggesting practical implications and future research

3. Citation and Reference Management

Apply citation styles correctly across disciplines. For comprehensive style guides, refer to references/citation_styles.md.

Major Citation Styles:

• AMA (American Medical Association): Numbered superscript citations, common in medicine
• Vancouver: Numbered citations in square brackets, biomedical standard
• APA (American Psychological Association): Author-date in-text citations, common in social sciences
• Chicago: Notes-bibliography or author-date, humanities and sciences
• IEEE: Numbered square brackets, engineering and computer science

Best Practices:

• Cite primary sources when possible
• Include recent literature (last 5-10 years for active fields)
• Balance citation distribution across introduction and discussion
• Verify all citations against original sources
• Use reference management software (Zotero, Mendeley, EndNote)

4. Figures and Tables

Create effective data visualizations that enhance comprehension. For detailed best practices, refer to references/figures_tables.md.

When to Use Tables vs. Figures:

• Tables: Precise numerical data, complex datasets, multiple variables requiring exact values
• Figures: Trends, patterns, relationships, comparisons best understood visually

Design Principles:

• Make each table/figure self-explanatory with complete captions
• Use consistent formatting and terminology across all display items
• Label all axes, columns, and rows with units
• Include sample sizes (n) and statistical annotations
• Follow the "one table/figure per 1000 words" guideline
• Avoid duplicating information between text, tables, and figures

Common Figure Types:

• Bar graphs: Comparing discrete categories
• Line graphs: Showing trends over time
• Scatterplots: Displaying correlations
• Box plots: Showing distributions and outliers
• Heatmaps: Visualizing matrices and patterns

5. Reporting Guidelines by Study Type

Ensure completeness and transparency by following established reporting standards. For comprehensive guideline details, refer to references/reporting_guidelines.md.

Key Guidelines:

• CONSORT: Randomized controlled trials
• STROBE: Observational studies (cohort, case-control, cross-sectional)
• PRISMA: Systematic reviews and meta-analyses
• STARD: Diagnostic accuracy studies
• TRIPOD: Prediction model studies
• ARRIVE: Animal research
• CARE: Case reports
• SQUIRE: Quality improvement studies
• SPIRIT: Study protocols for clinical trials
• CHEERS: Economic evaluations

Each guideline provides checklists ensuring all critical methodological elements are reported.

6. Writing Principles and Style

Apply fundamental scientific writing principles. For detailed guidance, refer to references/writing_principles.md.

Clarity:

• Use precise, unambiguous language
• Define technical terms and abbreviations at first use
• Maintain logical flow within and between paragraphs
• Use active voice when appropriate for clarity

Conciseness:

• Eliminate redundant words and phrases
• Favor shorter sentences (15-20 words average)
• Remove unnecessary qualifiers
• Respect word limits strictly

Accuracy:

• Report exact values with appropriate precision
• Use consistent terminology throughout
• Distinguish between observations and interpretations
• Acknowledge uncertainty appropriately

Objectivity:

• Present results without bias
• Avoid overstating findings or implications
• Acknowledge conflicting evidence
• Maintain professional, neutral tone

7. Writing Process: From Outline to Full Paragraphs

CRITICAL: Always write in full paragraphs, never submit bullet points in scientific papers.

Scientific papers must be written in complete, flowing prose. Use this two-stage approach for effective writing:

Stage 1: Create Section Outlines with Key Points

When starting a new section:

1. Gather the user-supplied evidence and, only when the section needs new current sources, use research-lookup or literature-review to collect them
2. Create a structured outline with bullet points marking:
   • Main arguments or findings to present
   • Key studies to cite
   • Data points and statistics to include
   • Logical flow and organization
3. These bullet points serve as scaffolding—they are NOT the final manuscript

Example outline (Introduction section):

- Background: AI in drug discovery gaining traction
  * Cite recent reviews (Smith 2023, Jones 2024)
  * Traditional methods are slow and expensive
- Gap: Limited application to rare diseases
  * Only 2 prior studies (Lee 2022, Chen 2023)
  * Small datasets remain a challenge
- Our approach: Transfer learning from common diseases
  * Novel architecture combining X and Y
- Study objectives: Validate on 3 rare disease datasets

Stage 2: Convert Key Points to Full Paragraphs

Once the outline is complete, expand each bullet point into proper prose:

1. Transform bullet points into complete sentences with subjects, verbs, and objects
2. Add transitions between sentences and ideas (however, moreover, in contrast, subsequently)
3. Integrate citations naturally within sentences, not as lists
4. Expand with context and explanation that bullet points omit
5. Ensure logical flow from one sentence to the next within each paragraph
6. Vary sentence structure to maintain reader engagement

Example conversion to prose:

Artificial intelligence approaches have gained significant traction in drug discovery 
pipelines over the past decade (Smith, 2023; Jones, 2024). While these computational 
methods show promise for accelerating the identification of therapeutic candidates, 
traditional experimental approaches remain slow and resource-intensive, often requiring 
years of laboratory work and substantial financial investment. However, the application 
of AI to rare diseases has been limited, with only two prior studies demonstrating 
proof-of-concept results (Lee, 2022; Chen, 2023). The primary obstacle has been the 
scarcity of training data for conditions affecting small patient populations. 

To address this challenge, we developed a transfer learning approach that leverages 
knowledge from well-characterized common diseases to predict therapeutic targets for 
rare conditions. Our novel neural architecture combines convolutional layers for 
molecular feature extraction with attention mechanisms for protein-ligand interaction 
modeling. The objective of this study was to validate our approach across three 
independent rare disease datasets, assessing both predictive accuracy and biological 
interpretability of the results.

Key Differences Between Outlines and Final Text:

Common Mistakes to Avoid:

• ❌ Never leave bullet points in the final manuscript
• ❌ Never submit lists where paragraphs should be
• ❌ Don't use numbered or bulleted lists in Results or Discussion sections (except for specific cases like study hypotheses or inclusion criteria)
• ❌ Don't write sentence fragments or incomplete thoughts
• ✅ Do use occasional lists only in Methods (e.g., inclusion/exclusion criteria, materials lists)
• ✅ Do ensure every section flows as connected prose
• ✅ Do read paragraphs aloud to check for natural flow

When Lists ARE Acceptable (Limited Cases):

Lists may appear in scientific papers only in specific contexts:

• Methods: Inclusion/exclusion criteria, materials and reagents, participant characteristics
• Supplementary Materials: Extended protocols, equipment lists, detailed parameters
• Never in: Abstract, Introduction, Results, Discussion, Conclusions

Abstract Format Rule:

• ❌ NEVER use labeled sections (Background:, Methods:, Results:, Conclusions:)
• ✅ ALWAYS write as flowing paragraph(s) with natural transitions
• Exception: Only use structured format if journal explicitly requires it in author guidelines

Integration with literature and citation skills:

Use the literature/citation skills only when the prose task needs them:

1. Use research-lookup for fast current paper discovery or targeted evidence gathering.
2. Use literature-review for field-level synthesis or single-paper evidence cards.
3. Use citation-verification when a source must be checked for existence or claim support.
4. Then convert the verified evidence outline to full paragraphs in Stage 2.

This two-stage process ensures you:

• Gather and organize information systematically
• Create logical structure before writing
• Produce polished, publication-ready prose
• Maintain focus on the narrative flow

8. Professional Report Formatting (Non-Journal Documents)

For research reports, technical reports, white papers, and other professional documents that are NOT journal manuscripts, use the scientific_report.sty LaTeX style package for a polished, professional appearance.

When to Use Professional Report Formatting:

• Research reports and technical reports
• White papers and policy briefs
• Grant reports and progress reports
• Industry reports and technical documentation
• Internal research summaries
• Feasibility studies and project deliverables

When NOT to Use (Use Venue-Specific Formatting Instead):

• Journal manuscripts → Use venue-templates skill
• Conference papers → Use venue-templates skill
• Academic theses → Use institutional templates

9. Journal-Specific Formatting

Adapt manuscripts to journal requirements:

• Follow author guidelines for structure, length, and format
• Apply journal-specific citation styles
• Meet figure/table specifications (resolution, file formats, dimensions)
• Include required statements (funding, conflicts of interest, data availability, ethical approval)
• Adhere to word limits for each section
• Format according to template requirements when provided

10. Field-Specific Language and Terminology

Adapt language, terminology, and conventions to match the specific scientific discipline. Each field has established vocabulary, preferred phrasings, and domain-specific conventions that signal expertise and ensure clarity for the target audience.

Identify Field-Specific Linguistic Conventions:

• Review terminology used in recent high-impact papers in the target journal
• Note field-specific abbreviations, units, and notation systems
• Identify preferred terms (e.g., "participants" vs. "subjects," "compound" vs. "drug," "specimens" vs. "samples")
• Observe how methods, organisms, or techniques are typically described

Biomedical and Clinical Sciences:

• Use precise anatomical and clinical terminology (e.g., "myocardial infarction" not "heart attack" in formal writing)
• Follow standardized disease nomenclature (ICD, DSM, SNOMED-CT)
• Specify drug names using generic names first, brand names in parentheses if needed
• Use "patients" for clinical studies, "participants" for community-based research
• Follow Human Genome Variation Society (HGVS) nomenclature for genetic variants
• Report lab values with standard units (SI units in most international journals)

Molecular Biology and Genetics:

• Use italics for gene symbols (e.g., TP53), regular font for proteins (e.g., p53)
• Follow species-specific gene nomenclature (uppercase for human: BRCA1; sentence case for mouse: Brca1)
• Specify organism names in full at first mention, then use accepted abbreviations (e.g., Escherichia coli, then E. coli)
• Use standard genetic notation (e.g., +/+, +/-, -/- for genotypes)
• Employ established terminology for molecular techniques (e.g., "quantitative PCR" or "qPCR," not "real-time PCR")

Chemistry and Pharmaceutical Sciences:

• Follow IUPAC nomenclature for chemical compounds
• Use systematic names for novel compounds, common names for well-known substances
• Specify chemical structures using standard notation (e.g., SMILES, InChI for databases)
• Report concentrations with appropriate units (mM, μM, nM, or % w/v, v/v)
• Describe synthesis routes using accepted reaction nomenclature
• Use terms like "bioavailability," "pharmacokinetics," "IC50" consistently with field definitions

Ecology and Environmental Sciences:

• Use binomial nomenclature for species (italicized: Homo sapiens)
• Specify taxonomic authorities at first species mention when relevant
• Employ standardized habitat and ecosystem classifications
• Use consistent terminology for ecological metrics (e.g., "species richness," "Shannon diversity index")
• Describe sampling methods with field-standard terms (e.g., "transect," "quadrat," "mark-recapture")

Physics and Engineering:

• Follow SI units consistently unless field conventions dictate otherwise
• Use standard notation for physical quantities (scalars vs. vectors, tensors)
• Employ established terminology for phenomena (e.g., "quantum entanglement," "laminar flow")
• Specify equipment with model numbers and manufacturers when relevant
• Use mathematical notation consistent with field standards (e.g., ℏ for reduced Planck constant)

Neuroscience:

• Use standardized brain region nomenclature (e.g., refer to atlases like Allen Brain Atlas)
• Specify coordinates for brain regions using established stereotaxic systems
• Follow conventions for neural terminology (e.g., "action potential" not "spike" in formal writing)
• Use "neural activity," "neuronal firing," "brain activation" appropriately based on measurement method
• Describe recording techniques with proper specificity (e.g., "whole-cell patch clamp," "extracellular recording")

Social and Behavioral Sciences:

• Use person-first language when appropriate (e.g., "people with schizophrenia" not "schizophrenics")
• Employ standardized psychological constructs and validated assessment names
• Follow APA guidelines for reducing bias in language
• Specify theoretical frameworks using established terminology
• Use "participants" rather than "subjects" for human research

General Principles:

Match Audience Expertise:

• For specialized journals: Use field-specific terminology freely, define only highly specialized or novel terms
• For broad-impact journals (e.g., Nature, Science): Define more technical terms, provide context for specialized concepts
• For interdisciplinary audiences: Balance precision with accessibility, define terms at first use

Define Technical Terms Strategically:

• Define abbreviations at first use: "messenger RNA (mRNA)"
• Provide brief explanations for specialized techniques when writing for broader audiences
• Avoid over-defining terms well-known to the target audience (signals unfamiliarity with field)
• Create a glossary if numerous specialized terms are unavoidable

Maintain Consistency:

• Use the same term for the same concept throughout (don't alternate between "medication," "drug," and "pharmaceutical")
• Follow a consistent system for abbreviations (decide on "PCR" or "polymerase chain reaction" after first definition)
• Apply the same nomenclature system throughout (especially for genes, species, chemicals)

Avoid Field Mixing Errors:

• Don't use clinical terminology for basic science (e.g., don't call mice "patients")
• Avoid colloquialisms or overly general terms in place of precise field terminology
• Don't import terminology from adjacent fields without ensuring proper usage

Verify Terminology Usage:

• Consult field-specific style guides and nomenclature resources
• Check how terms are used in recent papers from the target journal
• Use domain-specific databases and ontologies (e.g., Gene Ontology, MeSH terms)
• When uncertain, cite a key reference that establishes terminology

11. Common Pitfalls to Avoid

Top Rejection Reasons:

1. Inappropriate, incomplete, or insufficiently described statistics
2. Over-interpretation of results or unsupported conclusions
3. Poorly described methods affecting reproducibility
4. Small, biased, or inappropriate samples
5. Poor writing quality or difficult-to-follow text
6. Inadequate literature review or context
7. Figures and tables that are unclear or poorly designed
8. Failure to follow reporting guidelines

Writing Quality Issues:

• Mixing tenses inappropriately (use past tense for methods/results, present for established facts)
• Excessive jargon or undefined acronyms
• Paragraph breaks that disrupt logical flow
• Missing transitions between sections
• Inconsistent notation or terminology

Workflow for Manuscript Development

Stage 1: Planning

1. Identify target journal and review author guidelines
2. Determine applicable reporting guideline (CONSORT, STROBE, etc.)
3. Outline manuscript structure (usually IMRAD)
4. Plan figures and tables as the backbone of the paper

Stage 2: Drafting (Use two-stage writing process for each section)

1. Start with figures and tables (the core data story)
2. For each section below, follow the two-stage process:
   • First: Create an evidence outline from supplied material and only the lookup or review work the section actually needs
   • Second: Convert bullet points to full paragraphs with flowing prose
3. Write Methods (often easiest to draft first)
4. Draft Results (describing figures/tables objectively)
5. Compose Discussion (interpreting findings)
6. Write Introduction (setting up the research question)
7. Craft Abstract (synthesizing the complete story)
8. Create Title (concise and descriptive)

Remember: Bullet points are for planning only—the final manuscript must be in complete paragraphs.

Stage 3: Revision

1. Check logical flow and "red thread" throughout
2. Verify consistency in terminology and notation
3. Ensure figures/tables are self-explanatory
4. Confirm adherence to reporting guidelines
5. Verify all citations are accurate and properly formatted
6. Check word counts for each section
7. Proofread for grammar, spelling, and clarity

Stage 4: Final Preparation

1. Format according to journal requirements
2. Prepare supplementary materials
3. Write cover letter highlighting significance
4. Complete submission checklists
5. Gather all required statements and forms
