Our study, just published in #ScienceAdvances and funded by @hfspo.bsky.social, explores the post metamorphic cell composition of the sea urchin juvenile, revealing that its body is head-like. Long considered brainless creatures, they’re all brain instead!

Single-nucleus profiling highlights the all-brain echinoderm nervous system
A sea urchin is a head with a brain-like organization and a vertebrate-type retinal signature.

Mammalian cells have KSR, budding yeast has Ste5… and fission yeast has Sms1 as the MAPK scaffold for sexual reproduction!
Very excited to share my postdoc work where we discover that the hemi-arrestin Sms1 binds all components of the MAPK cascade, including ERK-like Spk1

The A–C linker structure!!! 🤩 Beautiful work. Even if you’re not as centriole-obsessed as we are, you’ll appreciate the elegance and complexity. Amazing to see U-ExM proteins in human centrioles fitting right into these densities. Congrats to all!
Huge congratulations to Wieczorek Lab PhD student Bin Cai and now-PI Jingwei Xu @xujwet.bsky.social on figuring out the surprisingly complex structure of the A-C linker crosslinking microtubule triplets in Tetrahymena basal body centrioles! www.science.org/doi/10.1126/...

Immagine you could image two cellular structures in the same fluorescent channel and still reliably get them separated afterwards…
What would you do with this?
Now… what would you do if that also worked with 4 structures at once? 👇 #MicroSplit #preview🧵

I found these immune cells just finished mitosis but their midbody is still yet to be resolved. How cool? If you zoom in to the midbody, you can see its classical shape just like in the textbooks. I love these little details.

1/6 Extremely happy to share my PhD work is out on bioRxiv! We discovered that microtubules deform mitotic centrosomes. When we removed them, the SPD-5 scaffold became denser but didn't lose material. This suggests it's an elastically deformable solid! This only happens in mitosis.
