Nikon's annual Small World in Motion contest, which showcases microscopic footage, recently crowned a winner whose video has sparked debate over the use of artificial intelligence in its production.
The winning entry, a short clip submitted by Dr Ning Xu of Tsinghua University, shows hair‑like cilia moving inside a child’s airway afflicted with a rare disease. Dr Xu says the footage is authentic and that AI was only used in post‑processing to enhance visual features within the constraints of the contest's rules.
However, several scientists and former judges have raised concerns that the image contains impossible shapes, sizes and movements that might indicate generative AI manipulation. Comments from researchers in the United States have highlighted “pop‑in” phenomena and unusual waveforms that were absent in the source data.
In response, Nikon has called Dr Xu “respectfully complying” with an ongoing review and maintains that no contest rules have been breached to date. The company has requested additional technical documents and promises to provide an update once the investigation is complete.
The controversy has highlighted the growing tension between scientific authenticity and the creative freedoms that digital tools offer. If the image is indeed altered, it could undermine confidence in scientific illustration and affect the perceived fairness of the competition.
