Drawing together findings from several projects over many years, we make a case that neural cell types in the Clytia larva have two embryological origins: i-cells and ectodermal.

Separation of the Early gastrula into oral and aboral halves shows that some neural cell tupes derive from aboral ectoderm, and others from i-cells

Happy There Is A Circulatory System Walking Through The Kitchen Day to all who celebrate.
It's an artistic representation of a circulatory system walking through a kitchen, as drawn by Dave Gibbons and written about by Alan Moore. It happens a lot 'round here.

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. 🧪🌊

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.

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🧵

Nature research paper: Chromatin loops are an ancestral hallmark of the animal regulatory genome

Chromatin loops are an ancestral hallmark of the animal regulatory genome - Nature
The physical organization of the genome in non-bilaterian animals and their closest unicellular relatives is characterized; comparative analysis shows chromatin looping is a conserved feature of genome architecture and spatial genome regulation emerged early in animal evolution.

Are animals of different sizes made of the same cell types?

The top left is a green and brown horned frog (aka Pac-Man frog). The top right is a pink and white flea beetle. The bottom left is a yellow slug. The bottom right is a kingsnake with grey and red scales. The background is light blue.

Public service announcement: this is *not* a dire wolf.

It is a genetically modified grey wolf made to resemble an extinct species, so a bullshit company can raise more money for their bullshit projects.

#deextinction is a scam on so many levels I don't even […]

[Original post on spore.social]
Time magazine cover showing Remus, a genetically modified grey wolf claimed to be a "dire wolf." The headline reads: "This is Remus. He's a dire wolf. The first to exist in over 10,000 years. Endangered species could be changed forever."
