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

Spionida (order) polychaete eggs and trochophores are really quite distinctive, with a sort of lattice-effect membrane going on. Excellent style choice!

Funny how everything can be traced back to the apical organ.

Check our latest pre-print where I’m a second author. We gathered evidence on the brain and nerve cord being specified autonomously by isolating blastomeres in two different annelid species. Great collaboration with @nicolewebster.bsky.social, @allancarbal.bsky.social and @biyolokum.bsky.social.
Weeeee! I’ve only ever seen one of these once before. This is the larva of an animal from the phylum Phoronida, which are kind of wormy, but feed using a lophophore, like a bryozoan.

I am thrilled to share our new open-access paper in Communications Biology!

Huge congrats to PhD student, June Ordóñez (not on bsky), whose beautiful and meticulous work led this project! 👏🔥

A detailed comic panel illustrating the life cycle of dicyemid parasites. Top text: "Despite their simple bodies of just a few cells, dicyemids have incredibly complex life cycles." Below that, a long brownish worm labeled "rhombogen" and a short brownish blob labeled "vermiform" are connected by arrows. The arrow leading from the rhombogen to the vermiform is "1. Adults make babies asexually" and the arrow leading from the vermiform to the rhombogen is "2. which grow into more adults." A separate arrow leads from the vermiform to a different brownish worm shape labeled "nematogen" and this arrow is "3. Sometimes they grow into different adults." An arrow from the nematogen to eggs and sperm is "4. which make babies sexually." An arrow leads from the eggs and sperm to the absolute cutest part of the life cycle, a round blob that looks like it has huge headlight eyes, though they are not actually eyes. The blob is labeled "infusoriform." An arrow leading from the infusoriform to an octopus is, "5. These different babies go infect new hosts!" I'M SORRY IT'S NOT MY FAULT THAT PARASITE LIFE CYCLES ARE SO STINKING COMPLICATED OKAY
At last, the dicyemid life cycle for #InverteFest! These absolute weirdos infect ONLY cephalopod kidneys; they are worms of discerning taste. 🦑🌊🐙🧪🐡

Pleased to share our latest paper led by @tomlewin.bsky.social, now out in @currentbiology.bsky.social! We present the first chromosome-level genome of a phoronid and show that shared chromosomal fusions unite phoronids and bryozoans as sister groups.

This resource was vital for my college training as a biologist and I still use it even as an embryologist. So sad to see it end but wishing a smooth transition. I hope we can all see and appreciate the value of taxonomy databases in -truly- understanding natural history.
@neva-meyer.bsky.social on behalf of @johnnyds.bsky.social is talking about the evolutionary and developmental origins of CNS in annelid worms #PASEDB2025 #spiralia #micromere #macromere
Excited to be heading to Woods Hole to start my summer as part of #embryology25 at @mblscience.bsky.social. Also proud to represent for annelids 🪱, my lab, my home country Peru 🇵🇪 and the LGBT+ community 🏳️🌈.
We are also raising money to support undergrads at UCSF this summer!
Help me, @neuronush.bsky.social and @quexarce.bsky.social buy ice cream and pizza for our little community of undergraduate researchers!
20% of sales for the rest of the month will go towards our programs!!!
Job Alert! We are recruiting one postdoc to work on spiralian embryos and their crazy polar lobes. More info about this HFSP-funded position on our website baronelab.org: scroll to the end, click on "this could be you"...start your adventure!
I may see a strange worm
Wow
Kyojiro Ikeda @beingkyo.bsky.social @univie.ac.at presenting now at #DevStem2025 @viennabiocenter.bsky.social on first mechanistic & molecular regulators of #bristle biogenesis in the #Platynereis model. Also check Kyojiro's recent @naturecomms.bsky.social publication www.nature.com/articles/s41...

Make sure you, your trainees, and anyone else who might listen to you understands what "indirects" actually are, how they are established, and what Universities contribute. H/T @rodallab.bsky.social

Please call your senators and representatives wherever you are located, it doesn't matter what party, and tell them you are against the current administration dismantling the NIH, research and technological advancement, and universities. This is happening right now. We scientists need your help!
The world: 🔥🔥🔥
Me: Do you want to know where this random Hox gene is expressed in annelids?
Not surprised at all, she’s fantastic. Congrats Ranny!!!
an email from the society for integrative and comparative biology that reads "Attn SICB Members: The past few weeks have been a stressful time in our scientific community, and we want to make our position clear: The Society for Integrative and Comparative Biology unequivocally condemns recent attacks on scientific integrity, funding for scientific research, and the importance of broadening participation in science."
This is how you do it.
Thank you @sicbjournals.bsky.social

Just downloaded all NIH reporter data 1985-2024, you can do it here, might come handy. Took me maybe 5', is 1 GB in size.

Here is the 2025 embryo alphabet from alligator to zebrafish. Developmental biology is stunning & leads to important discoveries for human medicine.
