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.
Methods explainer: bacterial regulatory networks and targeted validation
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.

Methods explainer: biochemical reconstitution and single-molecule measurements
Purified yeast proteins reveal how a temporary DNA bridge can delay end processing. The key control separates physical assembly from successful joining.
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.
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.
A laboratory study connects histone production with genome stability. It also shows why a metabolic assay, a direct cell count and a viability test should not share one label.
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.
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.

Tissue-specific mouse genetics and adipocyte experiments
Ankyrin-B loss produces different outcomes in fed, fasted and high-fat-diet settings. Our comparison keeps metabolic protection beside the cost of mobilising fuel in the cold.
