  • Eukaryotic ribosomal proteins contain nuclear localization signals (NLSs) that their bacterial counterparts lack. Here the authors compare homologous proteins from bacterial and eukaryotic ribosomes to show how NLSs could emerge in the course of evolution, and use this knowledge to identify novel NLSs.

  • Cells can simultaneously produce structurally dissimilar ribosomes, suggesting functional specialization of distinct ribosome populations. Here, the authors show that distinct ribosomes cooperate rather than specialize in protein synthesis.

  • Many parasitic organisms contain molecular structures that are drastically smaller than analogous structures in non-parasitic organisms. Here the authors describe a cryo-EM structure of the ribosome from E. cuniculi that reveals that it compensated rRNA truncations by evolving the ability to use small molecules as ribosomal building blocks.

  • A study identifies a new bacterial ribosome hibernation factor, Balon, and describes its association with EF-Tu and its initiation of mRNA-independent hibernation during protein synthesis.

  • A recent report on electrostatic field effect in superconducting devices provides a high potential for advanced quantum technology, but it remains controversial. Here, the authors report that the suppression of critical current, which was attributed to the field effect, can instead be explained by quasiparticle excitations in the constriction of superconducting devices.

  • The recent X-ray structures of the complete ribosome and large and small subunits from eukaryotes allow these structures to be compared to the previously determined structures of bacterial ribosomes. This Review describes bacterial and eukaryotic ribosomes as a conserved core and two specific shells and focuses on selected bacteria- and eukaryote-specific structural features and their functional implications.
