In our latest preprint, we show that the DPANN ARM-1 interacts with its host (AS-7) through intercellular proteinaceous nanotubes. Intriguingly, these tubes are assembled by the HOST, which likely suggests that the host also has a vested interest in this relationship!

Visiting some hot springs after the PSA-ISOP-ISEP meeting. These microbial mats look like a very nice place to live if you are a thermophilic cyanobacterium.

Happy to announce our paper about the GTRpmix model and exchangeability matrices designed for use with profile mixture models for eukaryote and eukaryote+archaea data sets is published: academic.oup.com/mbe/advance-ar…

Happy to present the outcome of a fun project carried out hand in hand with David Moreira. Did you know there's mitochondrial genome out there just as gene-rich as those of of jakobids? Why do we care, one might ask? Say no more! A thread 🧵 cell.com/current-biolog…

Many thanks to Michelle Leger and Ryan Gawryluk for their nice Dispatch commenting our work on Mantamonas mitochondria! sciencedirect.com/science/articl…

Today is the 125th anniversary of Jorge Luis Borges' birth. This is the original of 'The Aleph', one of the best texts ever written in Spanish.

It includes our (DEEM team Orsay ) work on hypersaline ecosystems in the Danakil depression, with microbial communities harbouring up to 99% of archaea. Go check these unique sites: nature.com/articles/s4155…

Many congrats to Carmen and all authors #Planctomycetota #Evolution #mitochondria : “Candidatus Uabimicrobium helgolandensis”—a planctomycetal bacterium with phagocytosis-like prey cell engulfment, surface-dependent motility, and cell division | mBio journals.asm.org/doi/10.1128/mb…

For evolutionary biologists interested in tracing genomes back to their ancient ancestors, we’ve developed EdgeHOG—a tool that reconstructs ancestral gene orders at an unprecedented scale and speed. #Genomics #EvolutionaryBiology #EdgeHOG Thread!

Give forams some time and they will build a mountain for you
