The paper from my postdoc days @mblscience.bsky.social and @zakswartz.bsky.social Lab is available in @natcomms.nature.com. www.nature.com/articles/s41... With Beverly Naigles, @carsten-wolff.bsky.social and @danivoronov.bsky.social

Fantastic seminar by Chris @lowelab.bsky.social. It’s been a real pleasure having you at @szndohrn.bsky.social these days. With @arnonelab.bsky.social

🔬 Meet Ina Arnone, ZooCELL PI at @szndohrn.bsky.social In this Q&A, she shares how she discovered EvoDevo, the big questions driving their research and her passion for mentoring the next generation of scientists. Follow the thread to learn more. 👇 #MSCA #ZooCELL #EvoDevo @arnonelab.bsky.social

(1/2) What a fantastic week for the Arnone Lab at #EED2026 in Glasgow! Our lab’s work was showcased through contributed talks by @perievodevo.bsky.social in S19 and @mlrusciano.bsky.social in S02, as well as an invited talk by Ina in S15.

we're on the cover!

At @szndohrn.bsky.social, the floor tiles have stitching and segmentation artifacts :) Just finished teaching the marvels of spatial omics to the great group of PhD students of @zoocell.biologists.social.ap.brid.gy, together with @alvarocrevenna.bsky.social. What a week! 🔬🍕🍝🍷🧪

Thrilled to present our comparative study on the evolution of zygotic genome activation (ZGA)!! 🥚🧬 Amazing PhD work of @campobes.bsky.social together with @fedemantica.bsky.social and many collaborators! @melisupf.bsky.social @crg.eu. Thread below 1/15 www.biorxiv.org/content/10.6...

These images show live embryos of animals (jellyfish, crustacean, worm, sea urchin, sea squirt, beetle) and one of animals closest single-celled relatives. They were captured taking advantage of fluorescent proteins localised on the outer membrane of cells, allowing us to observe cell outlines. 1/9

Finding molecular tags that localise fluorescent proteins to the cell membrane was the goal of our latest paper, now published in Development @dev-journal.bsky.social. The tags act as address labels, sending proteins to the cell membrane, where they highlight the shape and arrangement of cells. 2/9

Targeting the cell membrane in established and emerging model organisms

Summary: Screening a toolkit of diverse membrane-localising tags identifies candidates that efficiently localise proteins to the plasma membrane in a wide range of animals and choanoflagellates.

What a nice way to end the year - last shift of 2025 on the EMBL beamline P14 on Petra III in Hamburg! With @mlrusciano.bsky.social we did x-ray imaging of sea urchin larvae and had the honor of using the synchrotron ourselves! Many thanks to Angelika Svetlove. @embl.org

In preprints: cell type-specific gene regulation through the lens of echinoderms Periklis Paganos and @arnonelab.bsky.social discuss a recent #preprint by Jonas Maurice Brandenburg, David Aaron Garfield and colleagues doi.org/10.1242/dev....

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! www.science.org/doi/10.1126/...

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.

We discuss new research on sea urchins, how echinoderms remain relevant experimental systems in the multiomics era, and the future of the cell type evolution and development field.

We‘re thrilled to be involved in this great open science initiative; @mlrusciano.bsky.social really enjoyed testing this tool in sea urchins!

How can we see the cells that make up a living organism? Membrane-localising tags can drive fluorescent proteins to the cell's outer membrane, making their outlines visible. But the tags don't work well in all organisms. How do you find one for your species of interest? 🧵 Check our latest preprint

Very proud to be a part of this!
