Why did chloroplasts retain some genes from their free-living ancestors rather than transferring all of them to the nucleus following endosymbiosis? We suggest that mRNA targeting might play a role.

Does mRNA targeting explain gene retention in chloroplasts?
During their evolution from cyanobacteria, plastids have relinquished most of their genes to the host cell nucleus, but have retained a core set of geโฆ

Would you expect that Bacteria use an archaellum for swimming? We didn't, but we found that some Chloroflexota do! Find the story here:

Motility in Archaea is driven by a nanomachinery called the archaellum. So far, archaella have been exclusively described for the archaeal domain; however, a recent study reported the presence of arch...
