Ever wondered why snake embryos coil?🐍 A beautifully simple question with a fascinating answer: a growth mismatch between body & gut shapes the coil Our study from @helsinki-biotech.bsky.social @helsinki.fi with T. Miyashita & R.E. Diaz in @currentbiology.bsky.social www.cell.com/current-biol...

How snake embryos coil

Snake embryos coil, but how and why they corkscrew remains unexplored. Weber et al. find that the embryos wind up clockwise via buckling of the rapidly elongating axial body against the slow-growing, ...

Excited to share a new preprint from the lab, by @andrewmatheson.bsky.social and team, where we dive into the superpower of newts: plasticity! www.biorxiv.org/content/10.6... Like many good projects, this started with a serendipitous observation... 🧵1/5

So happy and proud to be part of this lab! Congrats guys! 🥳🫶

Congratulations to lab members @andrewmatheson.bsky.social , Tori Saltz and recent alumna @ecbjaeger.bsky.social on their #ICN2026 awards! Keep an eye on these rising stars and don't miss Andrew's and Tori's talks at @neuroethology.org this week

Drift into the deep with these living fossils. 🌊 MBARI's remotely operated vehicles have captured sea lilies swaying in the currents and feather stars paddling across the seafloor. Every observation helps reveal the incredible diversity of life in the deep sea. Dive in: youtu.be/GoQ-yGKrRgo?...

Better late than never... an update on the recent work from the lab. First of all, the Foundation: @astridd93.bsky.social phenomenal paper on the evolution of layering in the cerebral cortex 🧵1/7 www.biorxiv.org/content/10.1...

Buon 25 Aprile! On this day we celebrate the efforts and victory of the Italian resistance movement, and the liberation of Italy from fascism and from Nazi occupation! 🎉

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...

Whole-embryo spatial transcriptomics at subcellular resolution from gastrulation to organogenesis

Gene expression patterns underlie development, but their systematic detection in whole embryos has remained elusive. We introduce a whole-embryo imaging platform using multiplexed error-robust fluores...

New preprint from my PhD in @amphispacelab.bsky.social is out! 🥳 We investigated the evolution of my favorite gene FoxQ2 across 21 animal phyla, and found three ancient paralogs with a very dynamic history. More on phylogeny, synteny, and comparative in situs in the 🧵 below! tinyurl.com/2j96px45

Evolutionary dynamics of FoxQ2 transcription factors across metazoans: A tale of three ancient paralogs

FoxQ2 is a highly conserved class of Forkhead-box transcription factors expressed on the anterior side of the body in cnidarians and bilaterians. Despite this conserved expression pattern, recent phyl...

For my first post on 🦋, I am incredibly excited to share that my PhD paper has been published in #ScienceAdvances! We compared the development of the anterior neuroectoderm to uncover how the chordate #forebrain evolved 🧠. Have a look at the summary 🧵 below! www.science.org/doi/10.1126/...

An ancient apical patterning system sets the position of the forebrain in chordates

A conserved Wnt-regulated molecular signature sets forebrain position and identity in chordates.
