MIT's Bo Wang unveils X-Scientist roadmap: AI that proposes hypotheses and closes the discovery loop
BoWang87 · x · 2026-10-22
Bo Wang's team outlines the next phase of X-Scientist, an autonomous research agent aiming to become a "virtual drug hunter" that connects evidence, spots uncertainties, and picks the most informative experiments.
- X-Scientist already runs computational research: designing experiments, building models, evaluating results, and choosing next steps, with asynchronous model–harness co-evolution as a key mechanism toward recursive self-improvement.
- A liver-cell study showed a first continuous discovery loop: X-Scientist nominated perturbations, lab tests confirmed canonical and non-canonical targets, and feeding results back into X-Cell would close the loop — especially useful for combinatorial target discovery.
- The team is connecting X-Scientist to X-Automate, its AI robotics platform, to link scientific reasoning with automated wet-lab experiments.
