Nikon disqualifies Small World in Motion winner over generative AI use

Nikon has stripped Dr. Ning Xu of first place in its Small World in Motion competition after an investigation confirmed his video of moving cilia violated rules regarding generative AI.

The disqualification follows significant skepticism from the scientific community regarding the authenticity of Dr. Xu's entry, which claimed to show hair-like structures in the airway of a child with a respiratory disorder. According to BBC News, experts like Dr. Robert Hirst of the University of Leicester claimed the video appeared fabricated, noting that the cell features and cilia waveforms did not match those of actual patients. Ars Technica reported that some researchers spotted what appeared to be AI watermarks in the source files and noticed structural abnormalities where biological features appeared and disappeared unnaturally.

Dr. Xu, a researcher at Tsinghua University in China, admitted to using an unsupervised neural-network method for post-processing to visualize features in grayscale images. However, he denied using AI to generate the experimental movie or the motion of the cilia themselves. Nikon stated its decision to disqualify the entry was based solely on eligibility under competition rules and was not a judgment of Dr. Xu’s professional reputation or scientific intent.

Following the investigation, Nikon has named Nguyen Nam Nhat of Vietnam the new first-place winner for a video featuring a roundworm and a single-celled organism. Other finalists, including Benedikt Pleyer and Andrew Moore, have also moved up in the official rankings. The Verge reported that Nikon now plans to revisit its evaluation procedures and rules for future entries to address the challenges posed by generative technology.

The Small World in Motion contest, which focuses on photovideography through light microscopes, is a spinoff of Nikon's long-running photomicrography competition. Nikon confirmed the ruling after re-evaluating the submission materials and consulting with its judging panel.

Background

The Nikon Small World in Motion competition was founded in 2011 to showcase imagery captured through microscopes, expanding on the original Small World Photomicrography Competition established in 1974.
