Interrogate the evidence base
Pick a research theme to see where the science agrees vs is contested, the typical effect sizes, how the field is growing, and who the leading researchers are — across the full Pulse Brain catalogue.
Evidence base at a glance
Live figures over the full in-scope catalogue — the same metrics shown on the public At-a-glance and Pulse pages. Members see every metric, unlocked.

Researchers — who leads this field
Search a subject or research question to surface the leading authors, ranked by how many studies they have on the topic, then by citation influence. Re-scopes with the geography lens. Open any researcher to list their studies.
Explore by food category
Pick a commodity to see its evidence base — study count, evidence-tier mix, farming-system split and the strongest studies. Re-scopes with the geography lens above.
Practice × outcome — where's the evidence?
Study counts for each farming system against each nutrition & soil outcome — the "does this practice deliver this outcome?" view. Re-scope it by geography (lens above) and by research theme to see how the heat map shifts across topics.
Strongest-evidenced effects
The best-evidenced quantified effects, ranked by evidence tier, confidence interval and corroboration — not raw magnitude (units differ across studies). Pick a curated outcome, or search any topic to discover its strongest effects. Re-scopes with the geography lens.
Where are the evidence gaps?
Search any topic, practice or outcome to get an assessment of how strong the evidence is and how big the gap is — then dig deeper with Pulse Brain. Geography-aware.
Retraction & integrity checks
Every study with a DOI is cross-checked daily against Crossref / Retraction Watch. Pick an outcome to see whether any study in that evidence base has been retracted or flagged with concerns — and how much of it has been verified so far. Re-scopes with the geography lens.
