Chavez in 2009, while being labelled as paranoid, outlines exactly what is happening today.

Chavez blasted the U.S. empire. 'It is the most perverse empire in history: It talks about freedom while invading and destroying other nations.... The empire is very powerful, but not infallible. This century we will bury the U.S. empire. The empire has to face the people of Venezuela and Latin America. It has failed in Iraq already." He urged the audience to "imagine a world in which the U.S. administration declares peace to the world, withdraws its forces, and uses its resources to produce medicines and food for the poor people of the world."

The people of Venezuela do not deserve this. Solidarity with the people of Venezuela. May the words of Chavez give them some solace

Very happy to share my postdoc work (on preprint), where we try to understand a long-standing transcription-silencing paradox, and uncovered a hidden RNA decay arm of nuclear piRNA pathway, see detailed threads quoted from @juliusbrennecke.bsky.social

Happy to share that my PhD project is finally published!🪱✨
Selfish genes are found across the tree of life. They can disrupt inheritance patterns and at the same time act as units for molecular innovation. Here we tried to answer one big question: how do selfish genes emerge in the first place?

🚨 New paper alert!

Scientists in the Burga lab show for the first time how toxin-antidote elements—selfish genetic elements that perpetuate by poisoning those embryos that don’t inherit them—evolved from normal cellular proteins. More: https://imba.science/3M3fRyq

1/ How do animals develop immunity against a newly encountered transposable element from scratch? Our study reveals that the mobility of TEs is their Achilles heel, allowing hosts to develop a powerful small RNA-mediated silencing response.

MLL2 facilitates long-range gene regulation through LINE1 elements Transcriptional regulation is tightly linked to chromatin organization, with H3K4me3 commonly marking both active and bivalent promoters. In embryonic stem cells (ESC), MLL2 is essential for H3K4me3 d...

#Preprint alert! 📣

We are thrilled to share the work led by Lara Zorro-Shahidian and Lucio di Filippo, in which we show that #MLL2 controls gene expression in both #ESC and upon #differentiation by facilitating the #enhancer like activity of #LINE1 elements

Enhancer adoption by an LTR retrotransposon generates viral-like particles, causing developmental limb phenotypes - Nature Genetics Activation of an LTR retrotransposon inserted upstream of the Fgf8 gene produces viral-like particles in the mouse developing limb, triggering apoptosis and causing limb malformation. This phenotype c...

Finally out! 🥳 Our paper showing how a transposable element (TE) insertion can cause developmental phenotypes is now published @natgenet.nature.com 🧬🦠🐁
Below is a brief description of the major findings. Check the full version of the paper for more details: www.nature.com/articles/s41588-025-02248-5

GitHub - vierstralab/hotspot3: A chromatin accessibility peak caller with an adaptive background model A chromatin accessibility peak caller with an adaptive background model - vierstralab/hotspot3

We have created a new DNase I- & ATAC-seq peak caller that uses an adaptive background model that controls for copy number variation & aneuploidy. It performs a per-nucleotide test (+FDR correction) and is very fast. Please try it out and give us feedback!

Schematics depicting the dorsal and ventral sides of fins and limbs

We take for granted that our hands have two sides and can articulate in an endless number of ways. But what about a fish’s fin? Can a fish know something “like the back of its fin,” or have its future told with a fin palm reading? Check out this bluetorial to find out 👇🧪🧬🐟 doi.org/10.1101/2025...

Zincore, an atypical coregulator, binds zinc finger transcription factors to control gene expression Zinc finger proteins (ZNFs) are the largest family of transcription factors, yet how they activate gene expression remains unclear. In this study, we identified Zincore, a protein complex consisting o...

In today’s publication in Science we introduce Zincore: a novel protein of QRICH1 and SEPHS1 and functions as a transcriptional coregulator dedicated to zinc finger transcription factors. Here’s how we found it: 🧵 www.science.org/doi/10.1126/... 1/11

Co-evolving infectivity and expression patterns drive the diversification of endogenous retroviruses
@juliusbrennecke.bsky.social et al

www.embopress.org/doi/full/10....

only divergence. For instance, in regeneration we have situations where multiple differentiated cell states converge on a dedifferentiated identity before diverging again. Would emplying 3D spaces facilitate modeling these complex cyclic cases? 2/2

Hi, this is great! Had been looking forward to this after following all those UMAP threads. It's a very elegant solution. I was just left wondering what your thoughts were on whether this approach can be extended to also model situations where you have a convergence of cell states rather than 1/2

How does the genome find its place in the 3D space of the nucleus after fertilization?
