New #ISEPpapers by @DEEMteam! Reversal to osmotrophy in eukaryotes https://www.nature.com/articles/s41559-026-03088-0
"Distant eukaryotic lineages convergently reverted from phagocytic predation to osmotrophy through co-option of ancestrally acquired bacterial genes and their subsequent mobilization via eukaryote-to-eukaryote horizontal gene transfer."
