When people celebrate the individual genius of folks in science, they should also
mourn the collective loss of genius of folks who were actively discouraged or disadvantaged from a career in science because of the same person(s)

just in time for the opening of the @hohmannulrich.bsky.social group at @imbmainz.bsky.social
what started as a project on how cells export piRNA precursors, ended up as a tour de force in mRNA export. truly wonderful collaboration with @plaschkalab.bsky.social at the @viennabiocenter.bsky.social
New paper alert! Scientists in Clemens Plaschka’s lab at the IMP and @juliusbrennecke.bsky.social's lab at
@imbavienna.bsky.social solved a decade-old puzzle, uncovering how the information molecule mRNA travels from the cell’s nucleus to its periphery. More: bit.ly/4nHcvys

👇 Very sad. Science moves forward through questioning and uncertainty. Claims later proven wrong can only increase society’s distrust in science. We, scientists, should be able to acknowledge gaps without fearing a loss of funding or the impact on our publications...

Super cool! Again, how p-bodies control gene expression in cell fate transitions
1/ Excited to share our new study with @brumbaugh-lab.bsky.social, out in @natbiotech.nature.com! P-bodies selectively sequester RNAs encoding cell fate regulators, often from the preceding developmental stage. Releasing these RNAs can drive changes in cell identity. 🧵 www.nature.com/articles/s41...

We have a new preprint for you. Naked mole rats are very long-lived rodents and have increased translational fidelity.

Interestingly, 28S ribosomal RNA is split. Here we investigated the structure of the ribosome by single particle cryo-EM. Take a look.

Our paper on the optimization of smFISH to quantify cytokine mRNAs in T cells is published in EMBO Journal.
Using this protocol, we gathered interesting insights on cytokine mRNAs co-expression and localization in these teeny tiny human cells.

The 'Handler genome' of OSCs, a rare and stably growing cell line that runs a piRNA pathway to silence transposons.

Dominik (@86dominik.bsky.social) assembled the genome of this Drosophila cell line.

Besides making some cool findings, the goal was to turn this into useful resource for the field.
When transposons jump, genomes diverge - even in cultured cells.
I am happy to share our new preprint: a chromosome-scale genome assembly for Drosophila OSC cells, one of the key model systems in the piRNA field, especially for nuclear piRNA biology. 🧬🧵 (1/12)

Thrilled to share that I’ll be joining @imbmainz.bsky.social in February 2026 to start my own group!
We will explore new mechanisms in eukaryotic gene expression, leveraging ‘evolutionary play’ to uncover how regulation, repurposing, and hijacking shape RNA biology.
PhD positions available!

Historically, viruses were thought to primarily use host cell's translational machinery.

The specific motif built up by these two RBPs cannot be identified by studying each of them in isolation, so one important question we would like to raise is: How many RBPs form heteromultimeric complexes with specificity other than the sum of the individual RBPs?
This work was spearheaded by Masataka Suzawa in my (NIAMS) and Chen Qiu in Traci Hall’s lab (NIEHS IRP) and initiated together with Masashi Yamaji’s group at Cincinnati Children’s. Wonderful collaboration with @eugenevalkov.bsky.social and Vittorio Sartorelli.

Delighted to share the story of two germline RBPs - one with little (DND1) and one with no (NANOS3) intrinsic sequence-specificity - that together build a continuous RNA binding surface recognizing a 7-mer (AUGAAUU) in target mRNA 3’UTRs, leading to deadenylation.
