First paper of my PhD published 🎉

doi.org/10.1186/s129...

It's about immunity in acoel worms and its link to photosymbiosis. There's evolution and immune gene expression, but also mortality, dysbiosis, and host responses upon pathogen exposure.

With @hejnol.bsky.social and @rimskaya.bsky.social!
Absence of conserved immune signalling pathways and increased pathogen susceptibility associated to photosymbiosis in acoels - BMC Biology
Background Host immunity plays an important role in coral symbiosis with dinoflagellates. Photosymbiosis (the association between hosts and photosynthetic endosymbionts) has evolved multiple times wit...

Punkt 15 Uhr lief die Palästina-Demo los Richtung Innenstadt, begleitet von Polizei. Am hinteren Demozug wird die Stimmung zunehmend aggressiver, bislang habe ich aber keinerlei Kontakt gesehen.

Auffällig ist die hohe Dichte von rechten und Querfront-Streamern. #le1701

Our eLetter github.com/caseywdunn/s... responding to a recent Science paper was just posted. The paper found more genes with consistent support for sponge-sister than ctenophore-sister. We found several technical issues that, when corrected, reverse the conclusions and recover ctenophore-sister.

Wo kann man jahrzehntelang antisemitische Verschwörungsideologien featuren, die Shoah leugnen und eliminatorischen Antisemitismus verbreiten, lange bevor das im Trend war, und sich dennoch vor ausverkauften Hallen feiern lassen, als wäre nichts gewesen? In Deutschland #XavierNaidoo

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.

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.

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
