Happy birthday to Xenbase! Our research would have not been possible without you and your fantastic community support 🤩

Our preprint "Predictive design of tissue-specific mammalian enhancers that function in vivo in the mouse embryo" is on bioRxiv: www.biorxiv.org/content/10.6... . Amazing collaboration by @shenzhichen1999.bsky.social, Vincent Loubiere (@impvienna.bsky.social,@viennabiocenter.bsky.social),... (1/2)

Our new preprint is out: www.biorxiv.org/content/10.6... We show that GRN benchmarks commonly used can overestimate performance due to negative-sampling choices, sometimes allowing simple degree-based baselines to rival more complex GNNs. A reminder of why bias-aware evaluation matters!

After a long journey, I'm happy to share that my PhD work is finally published in Nature Communications. Grateful to all my co-authors!

We probably shouldn’t have favourites amongst projects in the lab, but this one was mine. I’m so pleased we can finally share it: Our work is now out in Nature Communications: 🔗 nature.com/articles/s41467-025-67692-7

A close-up piece on the legacy of Sir John Gurdon - so happy to see this out at @natcomms.nature.com. Excellent editorial and community work by @ebardot.bsky.social & thank you, @evahoermanseder.bsky.social et al.! www.nature.com/articles/s41...

We have just published a tribute to John Gurdon, reflecting on his scientific legacy and the profound influence he had on generations of developmental biologists. The piece is available open access in Nature Communications: www.nature.com/articles/s41...

We are honored to share our Perspective in Nature Communications, reflecting on the legacy of John B. Gurdon. Beyond his discoveries, his generosity and curiosity inspired a community of scientists-we remember and celebrate his lasting impact. #JohnGurdon #Xenopus #NatureCommunications

The Americans are doing to Kseniia what the Russians did to Brittney Griner for having 0.7 grams of cannabis oil. Except no one is coming to negotiate her freedom and Harvard is sitting on their hands. I am so ashamed. Please share this story. www.nytimes.com/2025/04/11/s...

#EpigeneticsPodcast with #HelmholtzMunich expert Dr. Eva Hörmanseder, @epihmgu.bsky.social! 🎧 Listen and learn about epigenetic memories & more: 👉 t1p.de/30q54 👉Check out her latest findings on this topic: t1p.de/43yrw @epigeneticspod.bsky.social #Epigenetics #Podcast #Reprogramming #CellFate

In the most recent episode we talked with @evahoermanseder.bsky.social from @www.helmholtz-munich.de‬ about her work on epigenetic mechanisms in cellular memory and gene regulation. #podcast #epigenetics Listen here: activemotif.com/podcasts-eva...

This is very disturbing. Harvard PhD student Kseniia Petrova (Russian citizen) was arrested by ICE for transporting xenopus embryos into Boston from Paris. She has been detained in Louisiana since Feb. 16. www.theguardian.com/us-news/2025...

If I could do it all over again, I’d apply here for my postdoc- look at these fantastic opportunities! ⬇️

Harvard scientist opposed to Ukraine war faces deportation back to Russia: Friends. This sounds like Trump trying to please Putin rather than anything to do with US immigration. www.independent.co.uk/news/world/a...

Our key collaborator, genius scientist and wonderful person Kseniia is in a horrendous situation right now, see article below. Why? Trump. Please share, please do not ignore, if you can, help. www.independent.co.uk/news/world/a...

Thank you very much for this possibility to contribute to this podcast! …but, as it said in my recommendation letter, “she has a tendency to talk fast” :) Thanks to everyone who contributed to these discoveries discussed here 🙏 Especially to those I forgot to mention cause I was so nervous…

🚨NEW PAPER ALERT! 3 of our teams at IES collaborated to understand why some cells reprogram effectively while others fail @hamperllab.bsky.social @antonio-scialdone.bsky.social @evahoermanseder.bsky.social Congrats to all the authors of this exceptional paper published @stemcellreports.bsky.social

Thank you Antonio for this great collaboration!

Cell Fate Changes – Transcriptional Memory in Reprogramming Dr. Eva Hörmanseder, #HelmholtzMunich & team uncovered why some cells resist reprogramming – a key hurdle for regenerative medicine. 👉 t1p.de/43yrw @epihmgu.bsky.social #CellReprogramming #Epigenetics #StemCells #RegenerativeMedicine

Do you work with reprogrammed cells? Then look at our new paper! We asked: How well do reprogrammed cells differentiate into complete&functional tissues? We found that - some cell types form perfectly but others fail - reducing levels of one specific TF of the previous lineage can fix problems⬇️
