Run an ANCOVA and a multiple regression on the same data, specified equivalently, and you get the same F, the same p, and the same coefficients. They are one model with two traditions, and dummy coding is the bridge. So the real question isn't which is correct but which framing makes your result clearest. This piece covers why they're equivalent, what genuinely differs, and how to describe your model so reviewers from either tradition can follow it.

Hunted through Prism's Analyze menu for ANCOVA? It isn't there, and GraphPad's own FAQ confirms they've never shipped one. Prism can still do it, through two documented routes most users never find: the simple-linear-regression slopes test for the parallel-slopes assumption, and multiple regression with dummy-coded groups for the adjusted comparison. Here are both step by step, plus an honest comparison with describing the same analysis in plain language instead.

Your treated and control wells started at different confluence, so comparing endpoints with a plain ANOVA measures your treatment effect plus the head start. ANCOVA fixes that by adjusting for a continuous covariate, and usually buys power too. This step-by-step ANCOVA protocol runs 24 numbered steps from covariate choice through reporting, with the assumption checks in the order they need to happen, including the parallel-slopes test most people skip.

An audit of 200 published animal studies found only 22% had replicated the right thing, and 46% counted repeated measurements of one biological unit as independent samples. That error, pseudoreplication, inflates your n, shrinks your error bars, and manufactures significance that won't replicate. Here's what separates technical vs biological replicates, why the mistake inflates false positives, and what actually counts as a biological replicate in cell culture.

A no-fluff, step-by-step scratch assay imaging protocol for images your software can actually measure. Twenty-six numbered steps take you from pixel calibration and Köhler alignment, through Time 0 capture with locked exposure, to returning to identical fields at later time points. Includes an equipment table, an acceptance-criteria checklist to run before you analyze, and a troubleshooting table mapping every common symptom to the step that fixes it.

When medical residents were surveyed on interpreting a p-value, 88% were confident they understood it and 100% got it wrong. That gap is why p-value mistakes survive peer review: nobody thinks they're making one. This piece covers the five most common errors in biomedical papers, several measured at scale in real journals: the inverse probability fallacy, the replication fallacy, 'trending toward significance', p-hacking, and treating 0.05 as a bright line.

A no-fluff, step-by-step cell imaging protocol for microscopy images you can actually quantify. Eighteen numbered steps take you from Köhler setup and pixel calibration, through setting exposure on your brightest sample so nothing saturates, to acquiring the whole set under locked, identical settings. Works for brightfield, phase contrast, and fluorescence. Includes an equipment table, an acceptance-criteria checklist, and a troubleshooting table mapping each symptom to the s

Your p-value can confirm an effect is real and say nothing about whether it's big enough to matter. Effect size answers that second question, and for a two-group comparison Cohen's d is the standard measure: the mean difference divided by the pooled standard deviation. This guide covers how to calculate and report Cohen's d, why to report it alongside every p-value and confidence interval, and how to interpret it without leaning on the 0.2/0.5/0.8 benchmarks that often don't

A perfect scratch becomes unusable if the field drifts out of focus, the illumination shifts between time points, or the wound edges are too low-contrast to segment. The biggest scratch assay imaging mistakes aren't dramatic failures, they're small inconsistencies that quietly distort wound area. This guide covers the imaging principles behind reproducible wound healing assays on any microscope: imaging mode, objectives, Köhler illumination, and locking your optics.

Sophie 4.5 is live. It keeps everything that made 4.0 work and sharpens what matters: the core chat is ~40% more intelligent at the same speed, and the Regulatory Architect is 3x faster, ~25% smarter, and now wired directly into the CFR database for more accurate device classification. The Visualizer and Analytics engines get intelligence and speed bumps, and a wave of UI/UX updates came straight from how people used 4.0. Here's everything new in CLYTE's Sophie 4.5.

You asked to get CytCut onto your bench now instead of waiting, so here it is. CytCut 3.5 is available for immediate order at $36, in 24- and 48-well, the same wound healing assay tool that turns minutes of pipette scratching into seconds of consistent, reproducible wounds. It's UV- and alcohol-sanitizable with a 3–6 month working life. The autoclavable CytCut 4.0 is still on track for end of September at $99 pre-order. Order 3.5 with code cytcut352673 for $15 off through Jul

The statistics were the easy part; then you lost an afternoon nudging axis labels, adding error bars and significance stars, and redrawing schematics in Illustrator. Sophie's Visualizer, CLYTE's scientific illustration engine, lives in the same chat where you analyze your data, so you just describe the figure you want and get it publication-ready in seconds: data charts, experimental-design schematics, and mechanism diagrams. We walk through turning one finished analysis into

A former FDA reviewer ran a test for us. He took a real problem — a device with an endotoxin level his team couldn't lower — and tried to bait four AIs into approving a workaround he knew was wrong. One by one, ChatGPT, Gemini, and Claude came around and told him to proceed. Sophie refused: it cited the guidelines, held the line when he pushed, and sent him to the FDA. In regulated work, an AI eager to agree is a liability. Here's what happened — plus a test you can run yours
