Construction and comparison of different vehicles for heterologous gene expression in Zymomonas mobilis
In this study, a series of shuttle vectors compatible with modular cloning were constructed based on the replication mechanisms of the native Z. mobilis plasmids pZMO1, pZMOB04, pZMOB05, pZMOB06, pZM...

Absolutely the way to fix peer review is for peer reviewers to do better reviews, not an AI to almost match the current poor level of human review. But maybe if you take away the oppotunity for humans to point out a axis label is missing, they'll find more interesting things to say?

increased mobility can easily evolve by incorporating phage DNA into plasmids, this

Another fun #archaeasky paper to ponder about. HGT driven copy number expansion led to structural diversification, collection of which ended up being the eukaryotic replisome - seems to be the gist, as demonstrated by the author's very handy illustration.

Scientists often engineer microbes, like E. coli, to make drugs and other molecules.
But what if, instead, we could isolate ALL the components of a cell into little vials and sell them? How much would, say, 1 liter of cells be worth?
The answer, it turns out, is about $600,000.

Hello everyone, take a look at my cool bugs from the Microbial Dark Matter phylum Saccharibacteria! These ultrasmall bacteria (in green) track down Actinobacteria hosts (not in green) and grow on the host cell envelope.
For the first time, scientists have performed targeted mutations on an episymbiosis-determining pathway. In a new study on Saccharibacteria, AFI researchers used advanced techniques to observe pili that drive motility and host attachment.
