Method Abstract: "Here, [investigators] used three-dimensional (3D) cryogenic electron tomography to determine the size and ultrastructure of intact ARMAN cells, a novel ultra-small archaeon, and sought evidence for their interactions with other members of its community."
Comments Abstract: "Within acid mine drainage biofilms, apparently free-living ARMAN cells from a deeply branched archaeal lineage have volumes of 0.009-0.04µm^3 (mean approximately 0.03+/-0.01 µm^3), only approximately 92 ribosomes, yet are frequent hosts for replicating viruses."
