  Membraneless channels sieve cations in ammonia-oxidizing marine archaea

  The Nitrosopumilus maritimus surface layer (S-layer) concentrates ammonium ions on its cell-facing side, acting as a multichannel sieve on the cell membrane.

  Isolation of an archaeon at the prokaryote–eukaryote interface

  Isolation and characterization of an archaeon that is most closely related to eukaryotes reveals insights into how eukaryotes may have evolved from prokaryotes.

  An anti-CRISPR viral ring nuclease subverts type III CRISPR immunity

  Bacteria and archaea use cyclic oligoadenylate molecules as part of the CRISPR system for antiviral defence; here, a family of viral enzymes that rapidly degrades cyclic oligoadenylates is identified and biochemically and structurally described.

  Accelerated growth in the absence of DNA replication origins

  When all origins of replication are deleted from the archaeon Haloferax volcanii, homologous recombination is used to initiate DNA replication and the growth rate is accelerated.

  Structural basis of highly conserved ribosome recycling in eukaryotes and archaea

  Cryo-electron-microscopy reconstructions of eukaryotic and archaeal ribosomes bound by ABCE1 and Pelota suggest a conserved mechanism for ribosome recycling.

  Formate-driven growth coupled with H₂ production

  The oxidation of formate and water to bicarbonate and H₂ is relatively common in microorganisms under anaerobic conditions. But can this reaction sustain growth in an isolated species? Here it is shown that several individual Thermococcus species can use formate oxidation for growth. Moreover, the biochemical basis of this ability is delineated.
