AI co-scientist: hypotheses validated in vitro on acute myeloid leukaemia (AML) and liver fibrosis
The gist
Google Research and DeepMind, with Stanford, present an AI co-scientist whose hypotheses were validated in vitro, in an article published by Nature on May 19, 2026.

What it changes
A peer-reviewed article describes an AI system that proposes testable biomedical hypotheses: existing drugs to repurpose against acute myeloid leukaemia (AML, a blood cancer) and leads against liver fibrosis. The validations cited remain in vitro (in the lab, outside a living organism), far from a treatment.
What remains unclear
The experiments are reported by the claimant and its collaborators; no independent reproduction is recorded. For the cf-PICI episode, published in Cell, the work is the human team's: the AI gave back the hypothesis ranked first (secondary source).

Accelerating scientific discovery with Co-Scientist
What it establishes : The authors describe a multi-agent system built on Gemini 2.0 that proposes research hypotheses, and report three laboratory validations: acute myeloid leukaemia, liver fibrosis and gene transfer between bacteria.
Where to start : The abstract, then Table 1 and Section 4 of v1: Sections 4.5 to 4.7 and Figures 10 to 13 cover the three validations. Version 2 is a rewritten text with different numbering.

Method
The Nature article (DOI 10.1038/s41586-026-10644-y), the published version of arXiv preprint 2502.18864, reports in vitro tests of drug-repurposing candidates for AML and of leads for liver fibrosis. Nature thanks two named reviewers, Olivier Elemento and Linfeng Zhang, and one anonymous reviewer. Status “peer reviewed” recorded on October 18, 2026 from nature.com (page read, quotation checked word for word). History: 2 dated observations, oldest first.
Limits
The status may change if a new source is published; the dated history stays visible.
