Nikon Reviews Award-Winning Microscopic Video After Questions About AI Use

A scientific video showing the movement of tiny structures inside a child’s airways has become the subject of an ongoing review after researchers raised questions about whether artificial intelligence was used during its processing.

The video was created by Dr. Ning Xu and won first place in Nikon’s 2026 Small World in Motion competition. The competition celebrates videos that reveal microscopic biological processes that cannot easily be seen with the naked eye.

A Window Into the Human Body

Xu’s winning video shows airway cilia, tiny hair-like structures that help move mucus and debris out of the respiratory system.

The sample came from a child with primary ciliary dyskinesia, a rare genetic disorder in which these structures do not function normally. Studying their movement can provide important information about how the condition affects the respiratory system.

Xu used diffractive super-resolution microscopy to capture the movement. The technique allows researchers to observe living biological structures at very small scales while limiting the amount of light reaching the sample.

Why the Video Attracted Attention

After the winning entry was announced, researchers began examining the footage more closely. Some scientists said they noticed structures and movements that appeared biologically unusual and questioned whether AI-based processing could have altered parts of the original data.

The concerns are significant because scientific images and videos are expected to represent observed data accurately. Even when digital processing is permitted, researchers need to distinguish between improving an image and generating information that was not present in the original observation.

Nikon Begins a Further Review

Nikon has said it is carefully re-reviewing the information supplied by Xu, including additional technical documentation about the equipment, imaging methods and processing techniques used to produce the video.

Xu has said that AI was used during post-processing, but he has disputed the suggestion that the video itself was generated by AI. According to reports, he described the technology as part of the process used to distinguish and color structures in reconstructed data.

Nikon has not announced a final decision about whether the entry violated the competition’s rules.

Why Scientific Imaging Matters

Microscopy competitions are not only about producing visually striking pictures. Videos of cells, microorganisms and tissues can also help researchers communicate complex biological processes to a much wider audience.

In this case, the video drew attention to a rare respiratory disorder while also highlighting an emerging challenge for modern science: how to use increasingly powerful digital tools without changing what the underlying evidence actually shows.

The Review Is Still Ongoing

The 2026 competition originally attracted hundreds of entries from researchers and imaging specialists around the world. Xu’s video was selected as the winning entry before questions about its processing emerged.

For now, Nikon’s review remains ongoing. The outcome will depend on the technical information and original data supplied by the researcher and the competition organizers’ assessment of whether the processing complied with the rules.
