Writing Scientific Papers

Key Principles from Whitesides, Weitz & Suo Labs

A synthesis of best practices for effective scientific communication
Slide 2

The Golden Rule

Start Writing Immediately

"Start drafting the paper the moment that you have a point to make, or a hypothesis to test."

Why This Matters

Writing helps organize your thinking and guides your research. Don't wait until experiments are "finished" - there's no such thing as finished until the paper is published.

📚 Transparent Review Insight

In the papers you reviewed, notice how authors who started writing early had more complete methods sections and clearer research narratives. Papers with "last-minute" writing often have inconsistencies that reviewers catch.

The Living Document Approach

Use the same document from hypothesis to publication. Keep refining your outline, abstract, and figures as your understanding evolves.

"A paper is not just an archival device for storing a completed research program; it is also a structure for planning your research in progress."
Slide 3

Write Your Conclusion First

The Most Important Sentences

Before anything else, write 1-2 sentences summarizing your main point. This determines what the entire paper is about.

Example Conclusion Statements:

  • "Degradable polymers commonly erode by hydrolysis, but hydrolysis makes cracks greatly outrun erosion."
  • "Lithiated silicon is capable of inelastic deformation at sufficiently small length scales."
  • "A highly entangled polymer network has both high modulus and high fatigue threshold."

📚 Transparent Review Insight

In your review assignment, identify papers where the conclusion was unclear in the original submission. Notice how reviewers asked "What is the main contribution?" - a sign the authors didn't clarify their conclusion early enough.

Important

Never be afraid to revise these sentences as you write. Clarity about your main point may emerge during the writing process. If you change it, rewrite relevant sections - this always leads to a better paper.

Slide 4

The Power of Outlines

Most Efficient Way to Write

An outline is a written plan of the organization of a paper, including the data on which it rests.

What Your Outline Should Contain:

📚 Transparent Review Insight

Look for papers in your assignment where the organization seemed disjointed. Reviewers often comment on "lack of logical flow" - a sign the authors didn't develop a strong outline before writing.

Slide 5

Writing the Introduction

Key insight: The introduction is the most important part of the paper. It determines whether readers continue and whether editors accept.

The Winning Structure (5-Step Process):

  1. General topic sentence - Broad context
  2. Establish importance - Why this matters scientifically and technologically
  3. Review literature concisely - What is already known
  4. Identify the gap - What is still unknown
  5. Your contribution - What you discovered/did

📚 Transparent Review Insight

In your assignment, find papers where reviewers said "The introduction doesn't clearly state the research gap" or "Motivation is unclear." Notice how authors strengthened these sections in revisions.

Nature Summary Paragraph Structure

What is the problem? (General audience → Specific audience)

What is new? (Your findings and approach)

Who cares? (Significance and impact)

Slide 6

Figures Drive the Story

Choose Figures Before Writing Text

Figures should be chosen to make the point of your conclusion. Write detailed captions that tell a self-contained story.

The Golden Rule of Figure Discussion:

Describe what you're showing BEFORE saying "in Fig. X"

Readers' eyes go to the figure when you reference it, breaking text flow. Tell them what to look for first.

✓ DO

"The polymer network shows high fracture toughness even at 90% water content, as shown in Fig. 3."

✗ DON'T

"In Fig. 3, we show the fracture toughness of the polymer network at different water contents."

📚 Transparent Review Insight

Look for reviewer comments like "Figure X is confusing" or "Caption doesn't explain key elements." These are signs the authors didn't develop figures with clear storytelling in mind.

Caption Strategy

Make captions self-contained stories. You can always move caption content to main text later if needed.

Slide 7

Make Your Paper Readable

"All papers should tell a story and should be interesting for the reader to read. This ensures they are read, understood, and cited."

Structure Strategy

  • Don't be historical - be clear
  • Present data in the order that best makes your point
  • Short papers rarely follow traditional format
  • Use the "hypothesis → test → proof" narrative

Grammar Guidelines

  • Use present tense - makes paper immediate
  • No parentheses in text
  • Avoid "i.e." - it's lazy writing
  • Use parallelism for emphasis

📚 Transparent Review Insight

Notice how reviewers respond positively to papers with clear narratives. Comments like "well-written" and "easy to follow" often correlate with papers that follow these readability principles.

Slide 8

Common Writing Pitfalls

Forbidden Phrases - Search and Destroy

✗ NEVER SAY

  • "In order to" → Use "to"
  • "On the other hand" (unless you said "on the one hand")
  • "We now describe..." → Just describe it
  • "It is instructive to..." → Just do it
  • "As a rule of thumb" → "In general"
  • "As discussed below" → Fix your flow

✗ AVOID

  • Starting sentences with "This"
  • Overusing "one..." without "another..."
  • Heaping multiple adjectives
  • Jargon without definition
  • Living people's names in text
  • Trite segues between sections

📚 Transparent Review Insight

Look for reviewer comments that specifically call out unclear phrasing or jargon. These are often the exact phrases we're discussing here.

Better Segues

Connect ideas naturally through content, not announcements. Find logical transitions that advance your argument.

Slide 9

Writing the Abstract

Write the Abstract LAST

After the rest of the paper is complete, you'll know exactly what to say.

The 2-2-1 Formula (Weitz Lab)

  • 2 sentences from Introduction
    (Context and gap in knowledge)
  • 2 sentences from Conclusion
    (What you found and what it means)
  • 1 sentence about importance
    (Why anyone should care)

📚 Transparent Review Insight

Compare abstracts in your assignment papers. Notice how abstracts that follow this formula are clearer and more compelling. Reviewers rarely question the significance when the abstract clearly states it.

Remember

Each sentence in the abstract should be supported by the main text. The abstract makes the title clear if it's not self-explanatory.

Slide 10

Stay Organized: The To-Do List

Be Explicit About Everything

State what needs to be done, how to do it, who will do it, and why (if not obvious).

Example To-Do Items:

  • "Measure toughness of the hydrogel using the pure shear test (Widusha)"
  • "Check if fracture energy depends on sample thickness (Widusha)"
  • "Derive approximate expression for critical fluid pressure using shear-lag model (Qihan)"
  • "Compare expression with FEM results (Qihan). This comparison is important because the model has several assumptions."

Integration with Writing

Your to-do list evolves as you write. Identifying gaps in your argument will reveal new experiments or analyses needed.

Slide 11

Learning from Transparent Peer Review

Behind the Scenes: The Complete Publication Journey

Published papers with review history show you the ENTIRE conversation:
Original submission → Reviews → Responses → Revised paper

What You Can Learn from Transparent Reviews:

🎯 How to Write Better Initially

  • What confused reviewers?
  • Which methods needed clarification?
  • What claims were too strong?
  • Which figures needed improvement?

✍️ How to Respond Professionally

  • Tone and language used
  • How to disagree respectfully
  • Evidence-based responses
  • When to add new analyses

👥 How to Write Review Comments

See what constructive, helpful reviews look like vs. unhelpful ones. Notice how reviewers identify core issues vs. minor details.

Slide 12

Writing Quality Directly Impacts Review Outcomes

Compare These Two Scenarios:

✓ Well-Written Paper

  • Clear introduction → Reviewer understands motivation
  • Complete methods → No questions about reproducibility
  • Self-contained figures → Easy to evaluate
  • Logical flow → Conclusions make sense
  • Result: Minor revisions or acceptance

✗ Poorly-Written Paper

  • Vague introduction → "What's the point?"
  • Missing details → "How did you measure X?"
  • Confusing figures → "What am I looking at?"
  • Weak logic → "This doesn't follow"
  • Result: Major revisions or rejection
From your transparent review analysis: Notice how many reviewer questions could have been prevented by following the writing principles we discussed today.

Key Insight from Modern Peer Review

With transparent review, your initial submission quality is now visible to everyone. This increases the importance of strong initial writing - not just for acceptance, but for your scientific reputation.

Slide 13

The Complete Cycle: Write → Review → Revise

Everything Connects

Good writing principles → Easier peer review → Better responses → Stronger science communication

Using Your Transparent Review Assignment:

  1. Read the original submission - What writing issues do you notice?
  2. Read the reviews - What did reviewers question or praise?
  3. Read the author response - How did they address concerns professionally?
  4. Read the revised paper - How did writing improve?
  5. Apply to your work - What can you do better from the start?
You now have the full toolkit: principles for writing, strategies for responding to reviews, and real examples of the complete process through transparent peer review.
