A study of healthy adults compares ten ways to describe brain activity. We explain what the measures share, where they differ and an unresolved detail in the paper.
Researchers combined two magnetic-resonance measurements in healthy men. Our guide follows the participants, the missing measurement and the limits of the comparison.

Methods explainer: cell migration and extracellular vesicles
Researchers describe relatively large vesicles shed by migrating cancer cells in laboratory models. We separate pooled DNA findings from claims about individual vesicles or patients.

Methods explainer: genomic surveillance and sampling
A Japanese One Health study compared bacterial isolates from food, animals and people. We explain why genetic similarity is a lead rather than a complete transmission history.

Methods explainer: cryo-electron tomography and cell division
Three-dimensional electron imaging maps the local arrangement of microtubules during cell division. We explain what a structural snapshot can and cannot reveal.

Methods explainer: cell images and machine-learning benchmarks
A model of protein-rich droplets suggests that enzyme activity can alter molecular mobility. The measurements are informative, but the droplets are not living cells.
A new microscope follows lipid-rich structures in three dimensions without fluorescent labels. We explain the speed, the separate chemical-imaging mode and what the demonstration does not yet show.
