What to know about 'Nature's algorithm' found in Chinese money plants

Researchers from Cold Spring Harbor Laboratory and other institutions have identified a naturally occurring Voronoi pattern in the leaf veins of the Chinese money plant (Pilea peperomioides). The study, published in Nature Communications, proposes a biological algorithm that explains how these plants organize their vascular systems without explicit distance measurement.

What happened

'Nature's algorithm' found in Chinese money plants Sadie Harley Scientific Editor Robert Egan Associate Editor Look up at the clouds.

Why it matters

As humans, we're prone to seeing patterns where they don't actually exist.

Common ground

This behavior is so common there's a name for it: apophenia.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
