How to publish in Nature (3-minute editor's advice) โ€œIt doesnโ€™t matter how beautiful your theory isโ€ฆ if it doesnโ€™t agree with experiment, itโ€™s wrong.โ€ โ€” Richard Feynman Dear Elite Researcher, We all would love to publish in the worldโ€™s highest-impact j...

What do you think matters most when sending your draft to Nature?

Surprise: It's not your track record!

On the left - western blot of B16F10 cells wt and KO for CDK8. Our in house produced antibodies give a lot of unspecific bands. On the right same probes with antibodies preincubated with fixed CDK8 KO cells - there is a specific band and faint unspecific bands, which can be probably eliminated with increase of amount of KO cells.

Neat trick if you polycolonal ab's suck. Incubate them with fixed cells with a KO of your protein of interest, then spin. Protocol here: www.med.upenn.edu/markslab/ass...
I was amazed how well it worked on first try (I'm sure that I can completely eliminate unspecific bands)

โœ… What to do instead

โ€ข Keep detector sensitivity high; ensure autofluorescence is above noise
โ€ข Stay in the linear range; adjust voltages so the brightest fluorochromes donโ€™t saturate
โ€ข If autofluorescence swamps a channel, move to lower-background dyes (red)

03.10.2025 05:21 โ€” ๐Ÿ‘ 0    ๐Ÿ” 0    ๐Ÿ’ฌ 1    ๐Ÿ“Œ 0

โŒ Wrong move.

โ€ข Autofluorescence is a cell-intrinsic property, not just noise
โ€ข Reducing sensitivity hides autofluorescence and your real signals
โ€ข The solution is experimental designโ€”choosing fluorochromes and channels that separate signal from background

03.10.2025 05:21 โ€” ๐Ÿ‘ 0    ๐Ÿ” 0    ๐Ÿ’ฌ 1    ๐Ÿ“Œ 0

Most unstained cells glow, especially under UV, violet, or blue lasers. This autofluorescence can overlap with weak signals โ€” which is why many users see it as a nuisance.

The common bad advice? Crank detector sensitivity way down so negative controls look dark.

Turning down the TV brightness won't remove static. It just makes everything else harder to see.

Lowering detector sensitivity in flow cytometry is the same. Instead, tune the โ€œchannelโ€ by picking fluorochromes that separate cleanly from autofluorescence.

Here's a very bad flow cytometry advice: โ€œautofluorescence needs to be minimizedโ€

Analogy: Imagine you're watching TV and you have static...

Takeaway:

1. Donโ€™t sink weeks into a fragile assay
2. Use high-throughput assays to discover
3. Use Western blots to validate the discovery

Heโ€™d be the one in lab meetings asking:

๐Ÿค”โ€œWhy do we accept Western blots failing half the time as normal science?โ€

Instead:

๐Ÿ‘‰ Heโ€™d push multiplex assays and large proteomics
๐Ÿ‘‰ He'd want to get a global view of cell signaling before looking at a single protein

He probably never did one, nor was he a biologist...

But Einstein hated finicky, low-reproducibility work.

He criticized โ€œstamp collectingโ€

i.e., piling up empirical details without deeper explanatory power.

5๏ธโƒฃ Tukeyโ€™s deeper point

Biology runs on plasticity, degeneracy, and context.

Your job isnโ€™t to oversimplify. Itโ€™s to frame questions that cut into the causal architectureโ€”even if the answers are noisy, probabilistic, or incomplete.

4๏ธโƒฃ Why this matters for a young researcher

Because they're pressured to publish โ€œclean data with tight error bars.โ€

The danger here is mistaking polish for relevance.

Approximate maps of meaningful processes outlast perfect dissections of trivial ones.

Example B - Right question, approximate answer: โ€œDoes inhibiting KRAS rewire in vivo signaling networks?โ€ --> Answered imperfectly with spatial transcriptomics or lineage tracing, but relevant.

3๏ธโƒฃ Examples from cancer research

Example A - Wrong question, exact answer: โ€œWhatโ€™s the ECโ‚…โ‚€ of this KRAS inhibitor in one colorectal cell line?โ€ --> Easy, precise, but tells you little about patient resistance.

2๏ธโƒฃ Precision โ‰  truth in living systems

Physics rewards exactness. Biology punishes it.

Transcript counts, single-cell trajectories, and proteomic hits are statistical shadows of moving targets.

A p-value to five decimals is meaningless without a good context.

For example...

The harder, โ€œrightโ€ question might be: โ€œDoes this perturbation rewire lineage commitment in a way that sustains heterogeneity?โ€

In this case, your answer will be approximate, but biologically richer.

1๏ธโƒฃ The right question is messy

A KRAS mutation means one thing in a 2D cell line, another in a hypoxic tumor niche.

So if you chase the exact fold-change of protein X after drug Y in 21% Oโ‚‚, youโ€™ll get pristine, reproducible dataโ€ฆ that says little about real tumors.

โœ… Donโ€™t reuse running buffers too often. Follow buffer recipes precisely (Tris-base, not Tris-HCl) and always check pH. Prepare fresh buffers regularly from stocks

โœ… Have your transfer apparatus ready to go as soon as your gel run stops. Avoid delays to minimize diffusion

โœ… Small proteins (<30 kDa) resolve best in high-percentage gels (12โ€“15%). Larger proteins (>100 kDa) need lower percentages (7.5โ€“10%) or gradient gels

โœ… If homemade gels consistently produce fuzzy bands, switch to commercial precast gels, made for consistent polymerization
