🚨 We discovered a new mode of Hox gene regulation in annelids! 🪱 A distal enhancer acts as a "global control region", lifting Hox genes from Polycomb repression. This is reminiscent of Hox gene control in vertebrates, but the two modes likely evolved convergently.

The Thermo Fisher situation keeps getting worse. We've now collected 450+ problematic images presented as verification data in TF's antibody catalog. This includes:
🖌️ Dozens more images with duplications or painting
🖨️ Hundreds of blots that all share the same background (behold slideshow below)

Bilaterian BMP signaling gradients suggest an ancestral anti-neural role. Study of #cnidarians shows that #BMP signalling promotes neurogenesis; its "anti-neural" function is a side effect of its role in the DV axis @paulknabl.bsky.social @genikhovich.bsky.social @plosbiology.org 🧪 plos.io/4dJHoiR
Just finished an incredible two month field season in Shark Bay #Gathaagudu - big thank you to all my wonderful team members 🙏🏻
So much appreciation for the animals and the time I get to spend with them. You have my heart Shark Bay 🫶
New preprint! In an fun collaboration with @imaeso.bsky.social and @mirimiam.bsky.social led by Manu F-M, we set to explore the potential adaptation of transposable elements đź‘ľ to host adenine DNA methylation by recruiting prokaryotic DAM methyltransferases: www.biorxiv.org/content/10.6.... 1/6

Astrangia poculata is an ideal model for coral development. Astrangia can be collected and induced to spawn in the laboratory, producing an abundance of embryos for experimentation.

Here’s the last major paper from the PhD of @paulknabl.bsky.social.
We were trying to understand what BMP signaling does in the sea anemone Nematostella when it is not patterning its second body axis. Check out Part 1 in BMC Biol. 2025; and here's is our Part 2

Bilaterian animals with centralized nervous systems have patterns of BMP signaling activity gradient that suggest an “anti-neural” ancestral role, but the evidence for this remains unclear. This study...
