Microscopy Contest Changes Winner Amid AI Claims

Nikon's 2026 Small World in Motion competition has seen its first-place winner disqualified for violating rules regarding generative AI. The original winning entry, showcasing the abnormal beating of airway cilia from a child with Primary Ciliary Dyskinesia (PCD), was removed after it was determined to not comply with competition standards. Nikon has not specified the exact nature of the AI breach. This disqualification has led to a reshuffling of the competition's top ranks, with the previously second-place entry now securing the top spot.

The condition, Primary Ciliary Dyskinesia, affects approximately one in 7,500 individuals globally, impairing the function of cilia responsible for clearing airways. The disqualification underscores the increasing difficulty in distinguishing authentic scientific imagery from AI-generated content, a challenge highlighted in recent scientific surveys where experts struggled to identify AI fakes. Nikon stated the decision was based solely on eligibility rules and not a judgment of the entrant's broader professional work. The company plans to review its rules and evaluation procedures for future competitions.
