Chlamydomonas in lab have a new year's resolution to practice their interpretive dances even if a flagellum/cilium falls off. I hope you enjoy as much as I do even if this is potato quality compared to fluorescence. (50 seconds long video)

Flagellar length control in Chlamydomonas is a paradigm for organelle size regulation. In poster 155 at the CellBio2025 meeting Sunday Dec 7, Ximena Garcia Arceo uses Lithium, which increases intraflagellar transport, as a tool to probe how length-altering mutants work.
