Google unveils Gemini-based 'AI co-scientist' with lab-validated hypotheses
Google Research described a multi-agent system built on Gemini 2.0 that generates, critiques, ranks and refines research hypotheses. Collaborators reported lab support for its proposals in three areas: drug repurposing candidates for acute myeloid leukaemia, epigenetic targets for liver fibrosis tested in organoids, and an antimicrobial-resistance gene-transfer mechanism that matched unpublished Imperial College London findings.
Why it matters
It marked the shift from AI as a prediction tool to AI as a hypothesis generator inside the research loop, the model later scaled up by agentic science efforts.
