After a long hiatus, happy #MicroscopyMonday! Here are some amoebae squeezing themselves into narrow channels (part of a video for our preprint pubmed.ncbi.nlm.nih.gov/41377514/).
Sound effects by Dillon (my 4 month old who may have had a little to do with the bluesky hiatus!)

It supports multi-file upload and now has the option to jitter the large dots (mean of median of replicates)
No jitter Jitter

For decades, cellular aggregation was considered an evolutionary dead end.
Cells could come together temporarily.
But complex multicellular organisms like animals?
Our study, led by JP Gerdt, with Ruibao & @jennahed.bsky.social suggests it may be time to rethink that🧵 #ProtistsOnSKy
This is my first paper.
A brief introduction of myself.
1 week to start🔥
New @focalplane.bsky.social webinar series focused on #CellMigration, register & join us▶️, it will be fun!
pls spread the word, in the next one, ECRs could apply to show their work ;)

(1/11) Excited to share the brand-new cell division preprint from the lab!
In this manuscript, chemical biology (in a collaboration with @rnett42.bsky.social Ryan’s lab) meets the cell biology (our lab).

Got to play around with Holotomographic imaging of muscle cells yesterday via the @uclastemcell.bsky.social imaging core and the results are pretty spectacular 🤩 You can see everything from mitochrondria to lamellipodia to macropinocytosis…with no labels!
For no reason at all, here is a picture of my dog on a ferry last summer
