Meet the winner of Nikon's Small World in Motion video contest
摘要
清华大学工程师徐宁凭借超分辨率视频，获尼康“小世界动态”显微视频大赛冠军。其作品展示了一名原发性纤毛运动障碍患儿气道纤毛的异常摆动。该遗传病会影响呼吸道纤毛功能，导致黏液和病菌堆积，引发感染。本届比赛共收到来自40个国家的346件作品。该赛事旨在通过显微视频展现微观世界的美丽与复杂。
A Chinese optical engineer is the winner of this year's Small World in Motion competition, sponsored by Nikon. Ning Xu of Tsinghua University in Beijing beat out 346 other video entries from 40 different countries with his super-resolution video (above) of the abnormal beating of cilia in the airways of a child with a rare genetic respiratory disorder.
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.
Primary ciliary dyskinesia (PCD) is a genetic disorder that adversely affects the tiny hairlike structures that line the lungs, among other areas. Their wavelike motion helps move around germs, mucus, dust, and other irritants so the body can dispel them via coughing or sneezing. In people born with PCD, there is something wrong with those cilia, so those irritants build up, causing respiratory infections, among other complications. The cilia might be the wrong size, the wrong shape, or missing altogether. They might move abnormally, or not move at all.
