Meet the winner of Nikon's Small World in Motion video contest
Summary
Ning Xu, an optical engineer from China, won Nikon’s Small World in Motion video contest with a high-resolution video showing abnormal movement of tiny hairlike structures called cilia in the airways of a child with a rare genetic disorder. The contest highlights detailed images and videos made through microscopes.Key Facts
- Ning Xu works at Tsinghua University in Beijing and uses advanced microscopy to observe living cells.
- The winning video shows cilia movement in a child with Primary Ciliary Dyskinesia (PCD), a genetic disorder affecting respiratory function.
- Cilia are tiny hairs that move mucus and irritants out of the lungs to keep them healthy.
- In PCD, cilia may be the wrong size, shape, or may not move properly, leading to lung infections.
- The microscopy technique used is called diffractive super-resolution microscopy, which shapes light carefully to see small, fast movements without harming the living cells.
- The competition began in 2011 as a video-focused spinoff of Nikon’s longer-running photomicrography contest started in 1974.
- Other winners came from Vietnam, Germany, the US, and Scotland, each showing different microscopic life forms and processes.
- The contest celebrates the beauty and science of seeing tiny life in motion through microscopes.
