This is either a stunning breakthrough in live imaging or AI slop. Sad that we can't tell which. It could be real if the cilia are beating slowly due to disease, if it's false coloring of a label-free image, and if it's very highly processed data. Many 'ifs' @healthcare.nikon.com

Check out this synopsis from Harry @yliu160.bsky.social on his new paper on the regulation of centriole architecture. And congratulations to Harry on starting his own lab @stonybrooku.bsky.social! You should work with Harry on all things centrosomal and ciliary!

Airway multiciliated cells make hundreds of centrioles (cyan) each of which extends a motile cilum (🔥). These cilia beat to move mucus and keep your lungs clear of dust, viruses and bacteria.
