The work that won Nikon's Small World in Motion competition has been re-evaluated after some scientists criticized the video as artificial intelligence.

This annual competition (Small World in Motion) accepts images and videos recorded with powerful microscopes and has been held annually for the past 15 years.

This year's winning entry was a short video submitted by Dr. Ning Xu, a researcher at Tsinghua University in China. This video purports to show the movement of very small wax-like structures called cilia in the airways of a child with a rare disease.

In response to criticism of his video work, Dr. Shaw did not deny the use of artificial intelligence in the "image processing process," but said he still acted within the rules of the competition.

Nikon, the organizer of this announced competition, is following up on the issue and said that Shaw is "respectfully cooperating in the research process" and has provided additional technical documents to the company.
