Nikon disqualifies Small World in Motion winner over AI rule breach

In short: Nikon has disqualified the original winner of its Small World in Motion microscope video contest after finding the entry broke its rules on generative AI.

What happened

Nikon’s Small World in Motion contest gives awards for short videos made through a light microscope, which is the common microscope used in many labs. Last month, Nikon named Ning Xu of Tsinghua University in China as the winner for a video showing tiny hair-like structures called cilia moving in a child’s airway.

After the win was announced, some researchers raised concerns about the video. They said parts of the cells seemed to appear and disappear in odd ways that do not match real biology. Others said they saw what looked like AI watermarks in the video’s source files.

Xu said he used AI to “distinguish and visualize features” in reconstructed grayscale images, meaning to help make faint details easier to see (like turning up contrast on a dim photo). He denied using AI to generate the cilia or their motion.

Nikon investigated and concluded the winning video did not follow the contest rules on generative AI, which refers to AI that can create or alter content, not just measure it. Nikon said the decision was only about eligibility under the rules, and not a judgment of the entrant’s reputation or intent.

Nikon has now named Nguyen Nam Nhat of Vietnam as the new first-place winner, for a video showing a tiny roundworm and a single-celled organism called Dileptus.

Why it matters

Science image contests rely on trust. This case shows how AI tools can blur the line between “enhancing what the camera saw” and “creating something new,” and Nikon says it will revisit its rules and review process.
