Happy There Is A Circulatory System Walking Through The Kitchen Day to all who celebrate.

Around extinction events, the shape of shells of certain groups becomes simpler. It's a sort of austerity measure to reduce the energy cost associated with producing a shell. Might be something we need to keep an eye out for in marine organisms now. 🧪🌊 Link: www.nature.com/articles/s41...

Join our "Advances in Single-Cell Technologies" meeting in December in Freiburg, co-organised with Marco Prinz and @katrinkierdorf.bsky.social. Excellent line-up of speakers covering spatial technologies, lineage tracing, computational methods, and more. www.uniklinik-freiburg.de/single-cell-...

A single-cell ATACseq atlas of our favourite sea anemone, Nematostella vectensis! By @aelek.bsky.social @martaig.bsky.social

Glad to see this paper finally out! An episodic burst of massive genomic rearrangements and the origin of non-marine annelids @natecoevo.nature.com @ibe-barcelona.bsky.social @csic.es @erc.europa.eu www.nature.com/articles/s41...

David’s @davidmoersdorf.bsky.social cool paper about the role of Chordin in BMP signaling in the sea anemone Nematostella is finally out www.science.org/doi/10.1126/...

The last part of @paulknabl.bsky.social 's PhD is now available at www.biorxiv.org/content/10.1... Paul showed that BMP signaling is active in the diffuse nervous system of the sea anemone Nematostella and the box jellyfish Tripedalia. Moreover, suppression of BMP signaling in Nematostella leads...

I’ve been studying gene regulation in primates for over 20 years, and using RNA-seq since 2008 to compare expression across species. We thought we were being careful. We used curated orthologous exons to minimize alignment bias and focused on biologically meaningful comparisons. We were wrong.

You want to apply #ATACseq in your emerging model organism, but you don't know where to start? Is #ATACseq the best method for my research questions? Search no more! We got you covered with our new review: doi.org/10.1002/jez.... Excellent collaboration with @gevol.bsky.social

Analyzing your single-cell data by mapping to a reference atlas? Then how do you know the mapping actually worked, and you’re not analyzing mapping-induced artifacts? We developed mapQC, a mapping evaluation tool www.biorxiv.org/content/10.1... from the ‪@fabiantheis lab. Let’s dive in🧵

It's finally here! Great start of the summer. We got our latest preprint from @chemamd.bsky.social in @qmulsbbs.bsky.social @qmulse.bsky.social, showing evidence of developmental system drift in the specification of dorsoventral (belly vs back) axis in annelids 🪱🪱🪱 #DevBio #EvoDevo

Proud to present the peer-reviewed version of our Cell Type Allometry paper, out today in Science Advances! www.science.org/doi/10.1126/... Are animals of different sizes made of the same cell types? Here’s an update of the main points and revision items (with memes!) Thread 👇🧵

Finally out - our paper on shell field and spicule #EvoDevo in a variety of #mollusks such as #scaphopods, #cephalopods, #aplacophorans, and of course #polyplacophorans. Among others we show evolutionary highly conserved gene expression in aculiferan spicules onlinelibrary.wiley.com/doi/10.1002/...

While we’re banning books… Finland is teaching children in school how to recognize fake news and propaganda as part of critical thinking and civic responsibility. Some of this will seem very familiar. Be. Like. Finland.

One of my favorite feelings is the joy of learning about an astonishing creature I previously had no idea existed. Most recent ex: the shingle urchin, which I initially mistook for a 3D printed aquarium ornament. Look at that iridescent mosaic of flattened spines! 🎥TikTok user discover.aquatics

We’ve looked at snails with one shell and slugs with no shells. Now let’s have a look at a snail with two shells, because Nature laughs at our puny attempts to pigeonhole. In today’s #AtoZ – J is for Julia (Juliidae) (1/9) Pic: © uwkwaj CC BY-NC

From octopuses to snails, the complicated molluscan family tree has now been mapped in unprecedented detail, researchers report in Science. Learn more in this week's issue: scim.ag/4hVhrxB

Our atlas of BMP signaling activity in adult Nematostella is finally out! Fantastic, meticulous work and beautiful illustrations by @paulknabl.bsky.social Thanks, @fwf-at.bsky.social for funding our work! bmcbiol.biomedcentral.com/articles/10....

We looked into details of the stem cell system of catenulids. Surprisingly, it was very different from the canonical neoblast-based systems of other flatworms. What does it tell about the evolution of stem cells and regeneration? Check in our latest paper in @naturecomms.bsky.social: bit.ly/3WK2ZzR

Latin America is a leader in nonprofit open-access, with pioneering platforms like Scielo and Redalyc. But it still struggles to have their journals valued at home, as researchers’ perfomances often depend on them publishing on mainstream commercial journals. www.science.org/content/arti...

We also profiled colony parts in the cnidarian Hydractinia – with @drsalamander.bsky.social @hrhorkan.bsky.social and @thecocodium.bsky.social – they are made of repeated parts interconnected by stolons, with shared cell types, but also part specific cell types www.biorxiv.org/content/10.1...
