Tn7 family transposons that include all of the guide RNA-directed transposons (CAST) are common in bacteria. We now find diverse representatives across archaea, with many in the Asgard group. Reviving an Asgard element confirmed the exciting behaviors of the family #MicroSky #TESky

Microbial metal physiology: ions to ecosystems
Nature Reviews Microbiology - Metal ions are required for all cells, and their homeostasis relies on ancient mechanisms that facilitate their import, distribution and storage. In this Review,...
Metal ions are universally required for life, and many of the foundational principles of metal homeostasis have emerged from studies of microbial systems. In this review, I provide a introductory overview targeted to those new to the field.

Telomeric transposons are pervasive in linear bacterial genomes
Eukaryotes have linear DNA, and their telomeres are hotspots for transposons, which in some cases took over telomere maintenance. We identified several families of independently evolved telomeric tran...
wow, telomeric transposons in bacteria with linear chromosomes! (of course this was first figured out in flies, inc by Bob Levis, who i was happy to see few days ago at the fly meeting). πͺ°
