Lipid imaging on the cover of @nature.com! Great times for lipid cell biology indeed. And a fantastic recognition of all the hard work by the team, especially Juan M. Iglesias-Artola and Kristin Böhlig (who made the cover). Link to article: www.nature.com/articles/s41...

Fantastical flowers, synthetic biology, and storytelling.

Giving an accessible science talk tomorrow at 10:40 UK time... come join!

Reshaping of a Glycoside Hydrolase Active Site through Expression-Compensated Droplet-Based Microfluidic Screening Provides Useful Tools for Glycomics The glycosylation of proteins endows them with distinct biophysical properties and allows them to play fundamental roles in cellular communication. Much of our understanding of glycoproteins has deriv...

Beautiful enzyme evolution work by Steve Withers and coworkers 👏

Olfactory floral mimicry of injured ants mediates the attraction of kleptoparasitic fly pollinators Mochizuki reports a plant that lures pollinating flies by imitating the scent of ants injured by predators. This study reveals the first known case of ant mimicry in flowers and uncovers previously un...

Although highly topical, kleptoparasitism does not get nearly the attention it deserves!

Here, a plant exploits the kleptoparasitic behavior of a fly that likes to snatch ants killed by spiders.

🕷️🐜🪰🌿

So the thief itself gets taken advantage of. Nice going, plants!

Molecular basis of polyadenylated RNA fate determination in the nucleus Eukaryotic genomes generate a plethora of polyadenylated (pA+) RNAs[1][1],[2][2], that are packaged into ribonucleoprotein particles (RNPs). To ensure faithful gene expression, functional pA+ RNPs, in...

How are RNAs sorted for export vs. degradation in the nucleus? In collaboration with @heick.bsky.social’s lab we (@clemensplaschka.bsky.social and @juliusbrennecke.bsky.social labs) discovered a direct mechanistic link between the export and decay machineries: www.biorxiv.org/content/10.1... (1/x)

I am excited to announce that I will be moving to IMB Mainz next year! The Winter call for the IPP PhD program is now open; if you are interested in maternal #mRNA regulation and #translation in early vertebrate development, please apply! Deadline: 16 October.

Wonderful news, and big congratulations to my dear friend, colleague, and brilliant scientist @obenaufa.bsky.social for winning this major Award! Super happy for you!

Ditto! Bravissima Anna 👏🏻

Join us for the 4th annual NonSeed Plant Meeting in Norwich this year! @johninnescentre.bsky.social

Just one more week left to get an application in! Starting my lab at the Perutz and the @viennabiocenter.bsky.social has been a fantastic opportunity that shaped me as a scientist!

Heartfelt congratulations @talbotlabtsl.bsky.social 🥳!

Looking for PhD or postdoctoral opportunities in #AI+biology #proteinengineering? the brilliant @arianemora.bsky.social has joined @aithyra.bsky.social in beautiful #vienna. I wish I could start over again!

A split-site E3 ligase mechanism enables ZNFX1 to ubiquitinate and cluster single-stranded RNA into ubiquitin-coated nucleoprotein particles Grabarczyk et al. show the structure and mechanism of a non-canonical ubiquitin ligase, which is activated through nucleic-acid-induced oligomerization and is critical for cell survival during immune ...

Happy to share our work on the structure and function of the unusual E3 ligase ZNFX1 @cp-cell.bsky.social. It uses a nucleic acid-activated transthiolation mechanism, ubiquitinating and clustering RNA to protect cells in an immune response. @clausenlab.bsky.social

piRNAs are essential for transposon silencing in the animal germline.
But how do hosts trap transposon sequences in genomic loci that help establish a piRNA response?

Looking at a natural transposon invasion, Baptiste Rafanel and Kirsten Senti made some remarkable observations.

Cyanophage Infections in a Sponge Intracellular Cyanobacterial Symbiont Intracellular cyanobacterial symbionts of sponges are shown to be susceptible to cyanophages, challenging assumptions about their isolation from viral exposure. The study reveals novel phage–host int...

Our paper on cyanophages of marine sponge symbionts is finally out. It is the outcome of a great collaboration with Laura Steindler's lab and was led by Tzipora Perez.

New preprint: In situ Architecture of #Plasmodesmata.
