Dr. Ning Xu's first-place video in the prestigious Nikon Small World in Motion competition was disqualified after scientists identified AI-generated content and structural abnormalities. The decision came weeks after researchers spotted telltale signs including AI watermarks and biologically implausible features in the footage of lung cilia movement.
Scientists Expose AI-Generated Content in Winning Entry
The Nikon Small World in Motion competition faced its first major AI controversy when Dr. Ning Xu's winning video was stripped of top prize after scientists identified generative AI use
1
. The video, which claimed to show lung cilia movement in a child with primary ciliary dyskinesia, was awarded first place on September 15 before researchers raised ethical concerns about its authenticity2
. Multiple scientists, including past judges of the Nikon microscopy competition, spotted structural abnormalities where cellular features appeared and disappeared in ways not seen in actual cellular biology4
.Detection Through AI Watermarks and Biological Implausibility
PhD student Ian Donovan at UT Southwestern Medical Center discovered AI watermarks embedded in the source files, including what appeared to be SynthID markers that Google embeds in AI-generated content
4
. An associate professor at the University of Florida noted that structures in the video would "pop in and out of existence" and cilia would "appear from nowhere"—classic indicators of AI-generated footage5
. Professor Pleasantine Mill of the University of Edinburgh, a cilia biology expert, stated bluntly on LinkedIn that "there is no grey here" regarding the video's authenticity4
.Contestant Admits AI in Post-Processing
In a now-deleted LinkedIn comment, Ning Xu acknowledged using "an unsupervised neural-network method" for AI-assisted post-processing to "distinguish and visualize features in the reconstructed grayscale images from the super-resolution optical imaging"
3
. However, Xu maintained he did not use AI to generate the experimental movie, the cilia, or their motion, and insisted he had not broken competition rules5
. This explanation failed to account for the biological abnormalities researchers identified, and doubts persisted as Xu did not share the RAW grayscale video that could have resolved concerns5
.Nikon's Investigation and Competition Rules Violation
After launching an investigation on September 25, Nikon Instruments announced on October 9 that the disqualified winner's entry violated competition rules regarding generative AI
1
. The company's statement emphasized the decision was "based solely on the submitted video's eligibility under the rules" and should not be interpreted as judgment of Xu's professional reputation or scientific contributions2
. A National University of Singapore spokesperson clarified that Xu participated in the competition before joining the university and his submission was unrelated to his work there1

.Broader Pattern of AI-Generated Content in Competitions
This incident reflects a troubling trend of AI-generated content infiltrating human competitions across multiple fields. A Midjourney image won a category in Colorado State Fair's art competition in 2022, while another AI creation won an Australian photography contest in 2023
5
. Even literary competitions face similar challenges—the publisher of Granta magazine admitted in May 2026 they may "never know" the true authorship of a Commonwealth prize-winning work accused of being AI-generated4
. The scientific imaging community now faces urgent questions about authentication standards as microscopy techniques and AI capabilities continue advancing rapidly, making detection increasingly challenging for competition organizers.References
