Have you ever wondered what difference it makes to have 1 or 2 X chromosomes in your cells? ✨ I’m excited to share that our paper is now out! Looking for some X-mas content featuring an actual X? 🎄 Here’s the paper: 👉 www.cell.com/current-biol...

Out today, our take on 6-methyladenine #6mA evolution in Eukaryotes @natgenet.nature.com. We asked a simple question, is really DNA 6mA common across the eukaryotes? The answer is "yes" if you're a unicellular eukaryote 🦠, not so if you're multicellular 🐝🌱🍄. www.nature.com/articles/s41... 1/9

Minister for Further and Higher Education, Research, Innovation and Science, James Lawless, TD, has today announced €34.5 million in funding to support 39 cutting-edge research projects under the Frontiers for the Future Programme. Read here: www.researchireland.ie/news/frontiers-for-the-future/

Nature suggests you use their "Manuscript Adviser" bot to get advice before submitting I uploaded the classic Watson & Crick paper about DNA structure, and the Adviser had this to say about one of the greatest paper endings of the century:

Chaetognaths have lost gene body methylation and shifted #5mC back to Transposable Elements. This reversion to the ancestral state is coupled with a simplification of DNMT3 architecture. We posit that trans-splicing might compensate. It is an honour to have contributed to this 20y struggle ⛰️.

We are excited to highlight our Rising Star Awardee, Dr. Can Aztekin @canaztekin.bsky.social whose work highlighting the importance of oxygen in regulating regeneration is inspiring. #Onetowatch

Announcing this year's Life Time Achievement Award. The one and only amazing Professor Brigette Galliot. Our inspiration with both her research and her service.

Cnidarian-Microbe Interactions Fully-funded postdoctoral position is available in the Gibson Lab at the Stowers Institute to investigate any aspect of cnidarian-microbe interactions. Strong background in coral symbiosis or eukaryotic microbiology preferred. Contact Matt Gibson: [email protected]

Happy to see our latest work out in @molbioevol.bsky.social. We revisit the evolution of 5-methylcytosine across neglected eukaryotic supergroups, establishing an ancestral repressive role silencing genome invaders, both transposons and viral elements👾: academic.oup.com/mbe/advance-... 🧵 1/7

Our study on a male-essential microRNA and the evolution of other dosage compensation mechanisms in birds is now out in Nature! www.nature.com/articles/s41...

🚨ISRB Webinar - Zone 2: Europe, West Asia & Africa on March 11th at 4pm Central European Time 📷 featuring Uri Frank and Stefano Tiozzo #ColonialRegeneration

The Hydractinia cell atlas is out. This remarkable animal has those cells, i-cells, that are pluripotent just like mammalian blastocyst inner cell mass. There is a difference, though––inner cell mass cells persist for only a few cell cycles before they differentiate; i-cells are adult cells.

Thrilled to receive a Discovery Award from @wellcometrust.bsky.social. We are working on adult, pluripotent stem cells in #Hydractinia. This animal is among the most regenerative creatures and does not succumb to age. Thanks to my team members and colleague at chromosome.ie @uniofgalway.bsky.social

Happy to formally announce I will be working on Nematostella again on the back of a recent @researchireland.bsky.social award! Also mazing to see 4/5 Frontiers for the Future awards to @uniofgalway.bsky.social announced today coming to PIs in the CCB (chromosome.ie)!

New insight on gonad morphogenesis ! Our new paper reveals how germ & somatic cells interact through TGF-Beta feedback loop to drive gonad morphogenesis in Hydractinia. Check out the full paper in Science Advances ! tinyurl.com/245rw699

Check out our new preprint looking at regeneration from reaggregated cell suspensions in Hydractinia. Once again i-cells are flexing their capacities

Gonads and germ cells have an interdependent relationship in the cnidarian #Hydractinia. Germ cells secrete a TGF-beta ligand (called Gonadless) to induce and maintain the somatic gonad; gonads activate Tfap2 in pluripotent stem cells (i-cells) to commit them to germ fate tinyurl.com/245rw699

Our first 2025 webinar is coming up in a few weeks - Jan 31st! Mark your calendars! @davidlabmsk.bsky.social will join us for her webinar on 'Turning back the clock: Targeting a new metabolism-epigenetic axis in T-cells.' Registration: us06web.zoom.us/webinar/regi... @activemotifusa.bsky.social

#Hydractinia takes regeneration to the extreme¬in a new preprint, Curantz et al. show that dissociated, reaggregated cells can form a new individual. We also show how they do it and which cells types actually contribute to the new individual (tip: not many of them). tinyurl.com/mr2s9zyf

Delighted with my lab's contribution to this study. We show that this feature of #miRNA is a general cnidarian trait. It has implications for understanding the evolution of miRNAs in animals. Was great to work with @yehumoran.bsky.social and his team!
