How did the anus evolve? Researchers led by evolutionary biologist Prof. Dr Andreas Hejnol from #UniJena, in collaboration with the University of Bergen, showed that in sea worms (Xenacoelomorpha), the sperm duct exhibits the same gene pattern as the later rectum.

Ich habe mir kurz die Mühe gemacht die jüngere Geschichte der politischen Morde in den USA anzuschauen. Zwischen 2005 und 2025 gab es 371 solcher Morde. 93% davon wurden von Tätern mit einem rechten oder rechtsextremen Motiv verübt. Quelle: Anti Defamation League.

It’s kinda #Ironic that an anus is required for us to have brains and many humans definitely use their anuses as brains.

Can confirm that my NSF grant "How False Beliefs Form & How to Correct Them" was cancelled today because it is "not in alignment with current NSF priorities" Shocking that understanding how people are misled by false information is now a forbidden topic. Our work will continue but at a smaller scale
NSF has posted an “update on priorities.”

They’re canceling all “DEI and misinformation/disinformation” grants.

And the guidance on how to fulfill the longstanding, legally mandated Broadening Participation requirement is utterly incoherent.

NSF says investigators can no longer propose to expand participation in STEM for women and underrepresented groups, and are terminating awards on diversity, equity, and inclusion (DEI) and misinformation/disinformation.

We may regard it as a humble part of the body, but the evolution of the anus was a major advance in animal evolution, laying down the fundamental bodyplan for most animals 🧪

Now @hejnol.bsky.social and co may have worked out how it came to be

www.newscientist.com/article/2473...
The anus may have evolved from a hole originally used to release sperm
The long-standing question of how animals came to have an anus may have been solved by studies of which genes are active during development in various animals

The last chapter of my PhD is finally out! Huge thanks to my supervisor @genikhovich.bsky.social for supporting “at first glance, stupid ideas” — which turned into a nice paper! That was so much fun!

In 2008 Mark and I proposed the idea about the relocation of beta-catenin nuclearization and the endomesoderm induction (doi.org/10.1016/j.de...). Now data by @genikhovich.bsky.social et al shows, that beta catenin does not induce endomesoderm in cnidarians. Progress! www.nature.com/articles/s41...
