Research Digests

Each time a major batch of strain research lands in the corpus, we summarize the story it tells.

November 8, 2026 195 papers

Three randomised results arrived, and none of them has been through peer review

Two are preprints and one is a doctoral thesis. Two of the three report no difference between the probiotic and the placebo. A strain page counts papers, so this is the kind of thing a count cannot show you.

October 25, 2026 234 papers

Abundance moved, and four papers checked whether it mattered

Akkermansia muciniphila took 23 of this batch's 64 scored links. Five of them stop at reporting that its abundance shifted. Four went further and tested whether the organism was carrying the effect rather than just accompanying it.

October 13, 2026 271 papers

Most of this batch used the strains as equipment

Three strains took 53 of the 84 scored links. Most of that work engineers them, encapsulates them, or writes standards for studying them, rather than measuring what they do in a person.

September 27, 2026 266 papers

The papers only one source had

Ninety one of this batch's 266 papers came from PubMed alone. Until this week none of them could enter the index at all, and the strain that lost the most to that gap is the one this catalogue tracks most closely.

September 13, 2026 303 papers

The strain being rebuilt, and the trial that found nothing

Escherichia coli Nissle 1917 is the primary subject of seven papers here, and every one studies an engineered version rather than a probiotic. The best powered human trial reported no effect.

September 2, 2026 825 papers

The strain with the most new research, and the trial that found nothing

Akkermansia muciniphila drew more new papers than any other organism in the catalogue. Its best powered human trial reported no effect on the outcome it was built to measure.

June 19, 2026 217,246 papers

The founding corpus: what the strain literature actually shows

The founding import indexed 217,246 papers across 445 strains. The finding that matters most is how little of that research has ever involved people.
