Super cool to see the result of our collaborative work with @heick.bsky.social 's lab finally out! Shaped through many discussions with @abugai.bsky.social, @lorenzoana.bsky.social & @max2max.bsky.social, @juliusbrennecke.bsky.social & Clemens, trying to decipher LENG8's secrets!

Nature research paper: Molecular basis of polyadenylated RNA fate determination in the nucleus go.nature.com/4vr9d7c

Now published! We investigated how polyadenylated RNAs are targeted for decay in the human nucleus. www.nature.com/articles/s41... (1/5)

How do cells distinguish functional genetic messages from molecular noise? Researchers in Clemens Plaschka's lab at IMP, together with Julius Brennecke's lab at IMBA and collaborators at Aarhus University, reveal a new principle of gene regulation: https://www.nature.com/articles/s41586-026-10650-0

Clear winter atmosphere, busy orbit.

Intrigued by a long-standing conundrum in small RNA biology—how nuclear Argonaute proteins silence transposons when they *need* target transcription for their own recruitment—we studied the piRNA pathway. And found a hidden RNA-decay axis from Piwi to the RNA exosome.

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!

Love RNA biology? Join us to explore the piRNA pathway with structural and genetic approaches (see 👇👇). PhD student/postdoc position co-supervised by Clemens Plaschka & myself. DM or email us if you’d like to know more! @vbcscitraining.bsky.social @imbavienna.bsky.social @impvienna.bsky.social

Check out our latest preprint, focusing on how nuclear decay and export compete for poly(A)+ RNAs utilizing the same biochemical mechanism.

First #Moon shot of June

Limited sleep on starry nights...

“Many” Ukrainian civilians killed in a Russian ballistic missile strike on Sumy as residents were heading to church for Palm Sunday services, local officials say. One of the missiles apparently hit a trolley bus. In other news, Witkoff’s sightseeing in St Petersburg seems to have gone great.

A world paralyzed by indifference, watching in silence as Russia slaughters civilians in Ukraine—year after year.

It’s now undeniably clear that Trump is attempting to blackmail Ukraine into making concessions to the aggressor.This is a critical moment for democracies —either they unite against rising autocracies, or risk a future shaped by authoritarian power and aggression www.theguardian.com/world/2025/m...

And it is downright foolish to think that the Vietnamese could ever have defeated the USA or the Afghans have defeated the USSR! We live in an age where policy makers wear their ignorance proudly.

First auroras of the year!

Latest piece out in @theatlantic.com . Europe better realize soon that Russia is fighting a “war” and it involves them.

At the right side of winter

Ukrainian anti-aircraft guns in Odesa countering a swarm attack by Russian Geran-2 drones. The West can stop this, just LET Ukraine strike back, we have our hands tied behind our back, being punched square in the face in the name of "escalation management".

The New York Times published an op-ed by a member of its editorial board calling for Ukraine to engage in negotiations with and cede territory to Russia after reports emerged that Putin is using backchannels and intermediaries to signal his interest in a ceasefire. Latest: isw.pub/UkrWar122823

The opportunity that @bsky.app has is clear. People are leaving Twitter in ever larger numbers. Hopefully Bluesky can scale up quickly. www.axios.com/2023/10/26/x...

Violent weather in #Aarhus today.

The ultimate goal is to leave that another network, which still gets some of my screen time. Hope #BlueSky makes it. #HiSciSky #EduSky #AcademicSky

I wish there will be more focused reviews like the one below: Noncoding snoRNA host genes are a distinct subclass of long noncoding RNAs And yes, I might keep here in #BlueSky my extremely nerdy #SciReadingClub #RNA #gene_regulation #EduSky www.cell.com/trends/genet...
