The logic of sabotaging the ability to hire trained researchers from abroad while simultaneously sabotaging the ability of US universities to train American researchers is truly baffling.

Check out our new paper: a review of translational coupling, the phenomenon where translation of one prokaryotic gene can promote translation of the gene downstream. We cover the history, and delve into the mechanism, which is still not fully understood. journals.asm.org/doi/10.1128/...

Translational coupling of neighboring genes in prokaryotes | Journal of Bacteriology

Prokaryotic genes are arranged in operons, with functionally related genes often located adjacent to one another (1). There are several ways in which the operonic organization of genes facilitates the...

While writing my thesis, I kept wondering why I was putting so much effort in something that "nobody will ever read". Well, someone did and thought it deserved a prize! 🤯
Many thanks to people @westermannlab.bsky.social and Alex in particular for the support, supervision and, eventually, nomination.

Congrats to Gianluca Prezza (@gprezza.bsky.social) for reveiving the 2025 PhD Award from the Friends of the Helmholtz Centre for Infection Research (HZI)!👏 The award honours excellent PhD theses from the field of life sciences at HZI partner universities. His thesis focused Bacteroides' RNA biology.

Bacteroides Theta-Iota-Omicron is polymorphic already in its name. What are the differences between the morphotypes? We tried to answer this with a combination of mechanical separation of cells based on their shape and an ultra-low input RNA-seq protocol. Paper from @elisebor.bsky.social here 👇

Did you think you needed a promoter for CRISPRa? Think again!

Sternberg Lab @sternberglab.bsky.social · Jun 11

6/10 dCas12f-Sigma factors are able to recruit their native RNA polymerase (RNAP) to drive RNA-guided transcription at programmable sites. Remarkably, we were able to generate RNA (see RNA-seq) without relying on promoters in intergenic sequences, even within genes, and on either DNA strand.
