Nikon 撤换「Small World in Motion」微观视频赛冠军后重排名次：新的第一名是越南研究者 Nguyen Nam Nhat 的一线虫与单细胞生物视频；此前有研究者指清华大学 Ning Xu 的原冠军视频存在结构异常、细胞特征以真实生物学中不会有的方式忽隐忽现，还有人发现源文件里疑似嵌着 AI 水印
AI disqualification yields new Nikon Small World in Motion winner

导读
上月报道过 Nikon「Small World in Motion」视频赛的冠军：来自中国清华大学的 Ning Xu，其作品拍到一名罕见呼吸系统疾病患儿气道中纤毛的摆动。随后出现关于 Xu 制作视频时使用 AI 的指控，Nikon 展开调查并认定该作品不符合赛事规则。新的第一名是越南的 Nguyen Nam Nhat，作品拍摄的是一条微小的线虫与一个单细胞生物。据 BBC 报道，一些研究者此前对 Xu 视频提出过质疑：认为其中存在结构异常，细胞特征的出现与消失方式在真实细胞生物学里不可能看到；另有人指出源文件中疑似嵌有 AI 水印。Xu 本人称使用 AI 是为了「在重建的灰度图像中区分并可视化特征」，但否认用 AI「生成实验影像、纤毛或其运动」。自 2011 年创办的 Small World in Motion 是 Nikon 自 1974 年起举办的 Small World 显微摄影大赛的衍伸，两者都是为了「展现透过光学显微镜所见之物的美与复杂」。随着 Xu 被取消资格，其余名次也依次上移：来自德国巴伐利亚的 Benedikt Pleyer 凭水滴中悬浮的水母幼体获第二名，霍华德休斯医学研究所的 Andrew Moore 以相邻细胞同步分裂的视频获第三，爱丁堡 Hypha Research 的 Patrick Hickey 以龟藤叶片细胞中线粒体与叶绿体动态的视频获第四，Igor Adameyko 以一只彩色小海蛞蝓（Cyerce kikutarobabai）移动的视频获第五。

Last month we covered the winner of Nikon's Small World in Motion video: Ning Xu of Tsinghua University in China, whose video captured tiny cilia beating in the airways of a child with a rare respiratory disorder. But allegations surfaced about Xu's use of AI while making the video. Nikon launched an investigation and concluded that Xu's entry did not comply with competition rules. The new winner is Nguyen Nam Nhat of Vietnam with a video of a tiny roundworm and a single-celled organism (above).
According to a BBC report, some researchers expressed concern that Xu's video had structural abnormalities and that cell features appeared and disappeared in a way one would not see in actual cellular biology. Others spotted what looked like AI watermarks embedded within the source files. Xu said he used AI “to distinguish and visualize features in the reconstructed grayscale images”; however, he denied that AI was used "to generate the experimental movie, the cilia, or their motion.”
Founded in 2011, the Nikon Small World in Motion competition is a spinoff of the company’s Small World Photomicrography Competition, which has been around since 1974. Both are meant “to showcase the beauty and complexity of things seen through the light microscope”—one through still photographs, the other through photovideography, taking advantage of all the technological advances that now allow users to make movies or time-lapse images through the microscope.
The other winners also moved up a notch with Xu's disqualification. Benedikt Pleyer of Bavaria, Germany, placed second with a video of jellyfish larvae suspended in water droplets; Andrew Moore of Howard Hughes Medical Institute in the US placed third with a video of synchronized cell division in neighboring cells; Patrick Hickey of Hypha Research Ltd. in Edinburgh, Scotland, placed fourth with a video of the dynamics of mitochondria and chloroplasts in Turtle Vine leaf cells; and Igor Adameyko placed fifth with a video of a tiny, colorful sea slug ( Cyerce kikutarobabai ) on the move.
