The Aporia
In the 2026 Nikon Small World In Motion competition, Dr Ning Xu from Tsinghua University in China won first place for a video showcasing cilia magnified 100 times in size. These hair-like structures line airways to clear mucus but move abnormally and impede lung clearance in individuals with primary ciliary dyskinesia (PCD). Xu employed complex light waves to illuminate the sample, aiding research into PCD.
The competition featured entries from around the world focusing on microscopic organisms and phenomena. Dr Nguyen Nam Nhat from Vietnam received second place for a video capturing an altercation between a microscopic roundworm and a single-celled organism called Dileptus. Additionally, other highly commended videos included bioluminescent algae and jellyfish larvae in droplets of water.
