The annual Small World In Motion competition, operated by Nikon for the past 15 years, recognizes exceptional photography and video captured through microscopes. This year’s winning entry was a video submission from Dr Ning Xu of Tsinghua University in China, depicting microscopic hair-like structures known as cilia moving within the airways of a child with a rare disease.
The competition has come under scrutiny following objections from multiple scientists who contend that artificial intelligence was used to create or substantially alter the winning entry in violation of contest rules. In response to these allegations posted on social media, Xu acknowledged that AI was employed in image processing to distinguish and visualize features in grayscale images, though he maintained that AI was not used to generate the experimental video, the cilia structures themselves, or their movements. The submission features artificial coloring, which is standard practice in microscopy and explicitly permitted by contest guidelines.
Scientific critics have raised several technical concerns about the authenticity of the video. Associate Professor Edward Phelps noted that certain structures appear and disappear inexplicably throughout the footage, while elements seem to materialize without explanation. Additionally, some observers have questioned whether the cilia dimensions align with typical cell behavior, and PhD student Ian Donovan identified what he characterized as an AI generation watermark in the source imagery. Two former competition judges have also expressed reservations about the entry’s legitimacy.
Nikon stated that Xu is cooperating with its ongoing investigation and has submitted additional technical documentation for review. The organization indicated it would provide further updates regarding the matter. In a statement, Nikon asserted that no rules violations have been identified based on its current assessment. Dr Patrick Hickey, who placed fifth in the 2026 contest, emphasized that the prestige of winning carries greater significance than the associated monetary prize, and stressed the importance of maintaining fair competition standards.
