Back in 2016, I spent some time centrifuging chambers containing a kinesin/microtubule -based active gel so that all the material ended up on one side of the chamber. Then recorded how long it took to expand.

Scientists of the #CytoMorphoLab adapted their protocols to illustrate the questions that keep them awake at night.
-> Two shows on the 24th and 25th of January.

New preprint! Do you like ocean waves? We found similar waves on bacterial colonies! We found that this collective behavior, known as rippling, is nothing but surface waves on an active nematic. @princeton.edu @mpipks.bsky.social @ub.edu @icreacommunity.bsky.social

For this week #FluorescenceFriday, we'll be treated with one of our favourite animal models 🐸 . Here is a Xenopus laevis embryo imaged with a Lightsheet microscope showing macrophage migration.
Purple🟣 = ectoderm nuclei, Red🔴 = macrophages.

Final result (better to do the rolling-ball background subtraction before merging, and merging using Max rather than blending)

So happy to announce our new preprint, “A geothermal amoeba sets a new upper temperature limit for eukaryotes.” We cultured a novel amoeba from Lassen Volcanic NP (CA, USA) that divides at 63°C (145°F) 🔥 - a new record for euk growth!

Still posting cytoskeleton videos, it seems. Actin this time.
Sample: Lifeact-eGFP in HeLa cells.
Modality: Airyscan confocal
Timestamp is mm:ss and the scale bar is 5 µm.

iPS cell-derived cardiac myocytes (heart muscle cells) typically beat about once per second, so I usually speed up the movies I post; otherwise, scrollers might miss the action. But every now and then, a cell looks like this in real time. #CellBiology
