#FluorescenceFriday: Given the recently grown interest in ciliary beating, here is a movie of beating cilia in a human airway model that I captured last week with lattice light-sheet microscopy. No AI „processing“, this is the raw data! Frame rate is ca. 170fps, displayed here at 25fps.

From the new info my bet is fluo labeling inference pushed to 11. Hallucinating nonsensical DAPI nuclei, mitochondria stain, membrane labeling from a kind of phase contrast image: wrong localization, wrong scale, wrong movement. Keeping this movie as SWiM winner is a disgrace to the competition
