This skill should be used when:

• Writing or revising any section of a scientific manuscript (abstract, introduction, methods, results, discussion)

• Structuring a research paper using IMRAD or other standard formats

• Formatting citations and references in specific styles (APA, AMA, Vancouver, Chicago, IEEE)

• Creating, formatting, or improving figures, tables, and data visualizations

• Applying study-specific reporting guidelines (CONSORT for trials, STROBE for observational studies, PRISMA for reviews)

• Drafting abstracts that meet journal requirements (structured or unstructured)

• Preparing manuscripts for submission to specific journals

• Improving writing clarity, conciseness, and precision

• Ensuring proper use of field-specific terminology and nomenclature

• Addressing reviewer comments and revising manuscripts

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.

7. 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

8. 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
