I am profoundly honored and grateful to be receiving the Impulscience Prize from the Fondation Bettencourt Schueller!

This grant will be the major support of my lab for the next 5 years.

Thank you for believing in our work and in our vision!

wonder what name you will come up for the "tiny arms" that are clearly not pili, not archaella, not pseudopodia either...
pseudobracchia ?

Dynamic protrusions mediate unique crawling motility in Asgard Archaea (Promethearchaeota) Crawling motility is a hallmark of eukaryotic cells and requires a dynamic actin cytoskeleton, regulated adhesion, and spatially organized signalling pathways1–3. Asgard archaea (phylum Promethearchae...

A collaborative project that began with the Osaka Expo has just been released as a preprint!
Here, we show Promethearchaeota (Asgard archaea) “moving” under anaerobic conditions.
The videos capturing this unique behavior are so fascinating you can watch endlessly.

Rare microbial relict sheds light on an ancient eukaryotic supergroup - Nature The discovery of an unusual protist named Solarion arienae, which has a mitochondrial genome with some intriguing features, provides insight into the early radiation of eukaryotic groups.

Each such discovery is a game changer for our understanding of eukaryote evolution, and this paper is no exception. Meet Solarion, which displays yet again novel types of subcellular structures. Congrats to all authors on a fascinating story. #protistsonsky

Bacterial natural transformation drives cassette shuffling and simplifies recombination in chromosomal integrons Abstract. Integrons act as biobanks of gene cassettes conferring functions crucial for bacterial defense, including protection against phages and antibioti

Our new paper is out in @narjournal.bsky.social We show that natural transformation enables bacteria to shuffle integron cassettes, boosting their phenotypic diversity.
