A new platform for cortical organoids makes a distinction that is easy to miss: producing a tissue-like structure and producing a well-patterned model are different outcomes.
Researchers compared Earth-made lunar and Martian dust simulants in cells and mice. The findings raise questions about airway barriers without measuring astronaut risk.
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.

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: 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.
