Overview
- Nikon disqualified the original first-place video Friday after a formal re-review concluded the entry did not comply with the competition's generative AI rules.
- Dr. Ning Xu acknowledged using an unsupervised neural-network method for AI-assisted post-processing while maintaining that the underlying cilia motion came from experimental footage.
- Independent researchers flagged biologically implausible changes in the clip, noted features appearing and disappearing unnaturally, and identified what looked like an AI SynthID watermark in the source files.
- Xu's entry was removed from the winners page, Nguyen Nam Nhat was promoted to first place, and other prize placements were adjusted in Nikon's updated rankings.
- Scientists and patient advocates have called for mandatory disclosure of AI edits, routine access to raw image data for verification, and clearer contest enforcement to protect scientific integrity and patient trust.
