Nikon Small World in Motion disqualified Ning Xu's video for using generative AI, awarding the title to Nguyen Nam Nhat of Vietnam. The decision followed an investigation into AI use in the 2026 competition. Xu's video, which captured cilia beating in a child's airways, was found to violate competition rules.
Nikon reported that Xu's video had structural abnormalities and AI watermarks, raising concerns among researchers. Some experts noted cell features appeared and disappeared in a way not seen in actual cellular biology. Xu claimed he used AI to visualize features in grayscale images but denied generating the experimental movie.
The Nikon Small World in Motion competition, a spinoff of the 1974 Small World Photomicrography Competition, aims to showcase microscopic beauty through time-lapse or video. The other winners also moved up in rankings after Xu's disqualification.
"After thoroughly re-evaluating the video and supporting materials, Nikon has determined that the winning video did not comply with the competition rules regarding generative AI," said Nikon in a statement. The decision reflects the need to revisit rules and evaluation procedures for future entries.
Nikon did not comment on Xu's professional reputation or scientific contributions, focusing instead on the video's eligibility. The decision highlights the challenges of balancing AI use with scientific integrity in imaging competitions.
