A new Klebsiella gene map asks who controls the pathogen

A map of 370 transcription factors links DNA binding, growth-stage expression and strain diversity. Our evidence guide separates a predicted connection from a tested biological effect.

How bacteria bypass an essential gene: what Sup-seq reveals

A new genetic screen finds compensating changes in pneumococcus. The useful result is not that essential genes are unimportant, but that their necessity depends on biological context.

DNA repair: holding broken ends together can change the next move

Purified yeast proteins reveal how a temporary DNA bridge can delay end processing. The key control separates physical assembly from successful joining.

The nuclear pore has distinct routes—but its map is not a movie

Live-cell mapping places eleven FG nucleoporins into a layered architecture. We explain what the reconstruction measures, how another method checks it and why a preferred location is not a fixed structure.

The IBD microbiome changes over time — and that changes the headline

A reanalysis of 4,839 public stool metagenomes asks which associations persist across time and bacterial strains. Our guide keeps specimens, people and inflammatory state separate.

Silk protein changes cell-to-cell signals in a mouse wound model

A mechanistic study asks whether a biomaterial can instruct tissue repair rather than merely support it. Our comparison separates wound closure, cell signalling and stronger claims about regeneration.

How mitochondria keep difficult protein sequences moving

A TACO1 structure, computational predictions and simulations offer different views of one flexible mechanism. Our guide shows which parts are observed, inferred or tested in earlier work.
