Nikon reviews microscopy contest winner over AI allegations
Nikon is re-evaluating the winner of its 16th annual Small World in Motion microscopy competition following allegations of artificial intelligence use. The controversy involves a video by researcher Ning Xu, formerly of Tsinghua University and currently at the National University of Singapore, which depicts the movement of cilia in a child with primary ciliary dyskinesia.
Members of the scientific community raised concerns regarding visual inconsistencies, noting that certain biological structures appeared to “pop in and out of existence” or did not match known biological dimensions. Some researchers identified a Google SynthID watermark, which indicates the presence of AI-generated or altered content. Competition rules strictly prohibit the submission of AI-generated videos.
Dr. Xu has defended his work, stating that while AI was used for post-processing to colorize grayscale data and distinguish structures, the original experimental footage and the movement of the cilia themselves were not AI-generated. Nikon has stated it is “carefully re-reviewing” the initial vetting information and additional technical documentation provided by the entrant.
