Kind: research · Impact: low

## In brief

- Scientists built what is described as the first single-cell atlas of a wild bird's heart.
- The atlas analyzes more than 200,000 cells and nuclei from newborn and adult Eurasian tree sparrows.
- The article frames the findings as parallels with human heart disease.

## Why it matters

A cell-level map of a wild bird's heart gives cardiovascular researchers a new comparative reference point for studying heart disease in humans.
