Accelerating scientific discovery with Co-Scientist

Google researchers have published a paper in Nature describing Co-Scientist, a multi-agent artificial intelligence system built on Gemini for structured scientific thinking and hypothesis generation. The paper, titled Accelerating scientific discovery with Co-Scientist and authored by Juraj Gottweis and colleagues, was published on 19 May 2026. Co-Scientist is designed to act as a collaborator to scientists and help accelerate the scientific discovery process. The system aims to help scientists discover new original knowledge. Conditioned on their research objectives and previous scientific evidence, it formulates demonstrably novel research hypotheses for experimental verification. These real-world validations demonstrate the potential of Co-Scientist to accelerate scientific discovery, according to the paper.
