## Summary

Ning Xu’s winning video in the Small World in Motion competition, organized by Nikon Instruments, depicts lung tissue cilia from a child with primary ciliary dyskinesia. The entry features red, purple, and blue structures below the cilia, which experts question as biologically implausible. Xu acknowledged using an unsupervised AI model for post-processing to enhance visual presentation but denied AI-generated content or claims about anatomical features.

Researchers like Melanie White and Markus Sauer warn that AI tools can distort scientific data if they misrepresent or exaggerate experimental findings. Edward Phelps noted the purple structures resemble mitochondria but lack biological plausibility, while the red stain’s identity remains unclear. Nikon updated its blog post on 22 September to disclose Xu’s AI use, but no further clarification has emerged.

## Key points

- Ning Xu’s AI-enhanced microscopy video won Nikon’s Small World in Motion competition on 15 September
- Experts question biological plausibility of purple/blue/red structures in his lung tissue sample
- Xu says AI was used only for post-processing, not generating experimental data or claims

## Why it matters

The controversy highlights risks of AI in scientific visualization: when models alter data for aesthetics, trust in research images erodes. Competitions must clarify AI use to maintain credibility in microscopy and beyond.
