Nikon announced that the video which had been awarded first place in its Small World in Motion competition is now disqualified. Dr. Ning Xu had used an AI‑assisted method to enhance the microscopy footage, which the contest rules forbid. The video showing cilia movement in a child’s airway has been taken down from Nikon’s site. Nguyen Nam Nhat’s entry is now listed as the winner. Nikon says it will review the rules for future contests.

## The facts

- Dr. Ning Xu admitted to using AI for post‑processing on LinkedIn.
- The disqualification was reported on Oct 9 2026.

## Why it matters

It shows contest organizers that AI‑generated content can breach competition rules, prompting tighter guidelines for future scientific imaging contests.
