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.

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.
