Really excited to share our new paper from @ibe-warszawa.bsky.social protist team! 🎉

We dive into protist symbioses and show how these interactions shape ecosystems and have played a key role in the evolution of eukaryotes 🦠

Fast and accurate multiple-protein-sequence alignment at scale with FAMSA2 - Nature Biotechnology FAMSA2 accurately aligns millions of protein sequences at high speed.

10 years after the first FAMSA paper, its successor is now published in Nat Biotech! We believe that FAMSA2 can enable analyses of large protein collections that were previously unattainable. Thank you, Andrzej and Cedric, for great collaboration

Latitudinal diversity gradients and selective microbial exchange at the Atlantic ocean-air interface Microbial communities at the ocean-atmosphere interface play a vital role in nutrient, aerosol, and water cycling, yet their large-scale biogeography remains scarcely studied. Here we assessed microbial cell abundance and community structure in air and surface ocean samples along a 14,400 km transect from the polar circle to the equator. Air and surface ocean microbiomes were taxonomically distinct across the North East Atlantic. The microbiome in the air had a lower local community richness compared to the surface ocean, yet was more diverse across larger geographical scales. Our results suggest that terrestrial-derived air masses affected air and surface ocean communities. Air microbial communities showed a latitudinal diversity gradient with richness and cell abundance increasing from the polar circle to the equator. We observed an exchange of microbial lineages between ocean and air, however, most lineages were confined to one realm, suggesting lineage-selective aerosolization and deposition of microbial cells. ### Competing Interest Statement The authors have declared no competing interest.
