Understanding evidence

A brain organoid formed. But did it develop the right features?

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.

Moon dust and the lungs: what a laboratory simulation can tell us

Researchers compared Earth-made lunar and Martian dust simulants in cells and mice. The findings raise questions about airway barriers without measuring astronaut risk.

One brain signal, several different answers

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.

What moving cancer cells leave behind: a closer look at MoVes

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.

A closer look at how a cell division spindle holds together

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

Can AI read a cell image? A large benchmark puts it to the test

Researchers compared AI image models with a traditional analysis pipeline. Our guide separates image retrieval from evidence that a medicine works.

When a crowded droplet becomes easier to move through

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.
