Nikon strips Small World in Motion winner of title over generative AI use
Nikon disqualified Dr. Ning Xu of Tsinghua University from first place in its Small World in Motion microscopy competition, saying the video "did not comply with the competition rules regarding generative AI." The entry had claimed to show tiny hair-like cilia beating in the airway of a child with the respiratory condition PCD, but researchers and two former judges raised concerns after spotting structural abnormalities, cell features appearing and disappearing, and what one PhD student described as an AI watermark in the source material. Xu acknowledged on LinkedIn that an unsupervised neural-network method was used for "AI-assisted post-processing" of reconstructed grayscale images, while denying AI generated the movie, the cilia or their motion. Nikon, which said the decision is not a judgment of Xu's professional reputation or scientific contributions, replaced him with Vietnam's Nguyen Nam Nhat and said it will revisit the contest's rules and evaluation procedures.
The case shows that as neural networks enter scientific imaging workflows, competitions and journals must draw clear lines between permitted enhancement and generated content to keep published images verifiable.
