Winning video disqualified for AI
Nikon disqualified the winner of its Small World in Motion competition after finding that Ning Xu of Tsinghua University in China used generative AI while making his video of respiratory cilia.
Researchers spotted AI signs
According to a BBC report, researchers noted structural abnormalities in Xu's video and saw cell features appear and disappear unnaturally. Some spotted what looked like AI watermarks in the source files.
Xu's explanation and denial

Xu said he used AI to distinguish and visualize features in reconstructed grayscale images, but denied that AI was used to generate the experimental movie, the cilia, or their motion.
“to distinguish and visualize features in the reconstructed grayscale images”
New winner and rankings shift

Nguyen Nam Nhat of Vietnam becomes the new winner with a video of a tiny roundworm and a single-celled organism. All other entrants moved up one place in the rankings.
Nikon to revise competition rules
Nikon said the disqualification shows the need to revisit rules and evaluation procedures for future entries, citing rapid advances in imaging and artificial intelligence creating new challenges.
The essence
Nikon disqualified its Small World in Motion video competition winner for using generative AI, promoting all other entrants and prompting the organisation to revise its rules.
