Nikon disqualifies competition winner for rule-breaking artificial intelligence use

Nikon has removed the top prize from its Small World In Motion competition after finding that the winning video broke its rules on artificial intelligence.

The video was submitted by Dr Ning Xu. It showed tiny hair-like structures, called cilia, inside a child's airway. The child had a breathing condition called PCD.

Several scientists said publicly that the video looked fake. They noticed that some structures appeared and disappeared in ways that seemed unnatural.
