Closed-loop AI scientists AI can generate hypotheses much faster than we can experimentally verify them. @AdaFang_ In our latest piece on Closing the Loop in AI-Driven Biomedical Discovery we outline a path for closed-loop AI scientists, https://t.co/FBo1oniHWb AI scientists https://t.co/S2Ie5p1PYG #ClosedLoopAI #BiomedicalDiscovery #AIScience #Nospecificcountrycodesarementionedinthetweet.

@GaoShanghua @ayushnoori @CurtGinder @BenGlicksberg @RanBalicer @HarvardDBMI @KempnerInst @biohub @IcahnMountSinai @ClalitHealth @BrighamWomens 🟢 Benchmarking: Across 3,168 drug reasoning questions (DrugPC) and 456 patient specific treatment cases (TreatmentPC), ATHENA hit 94.7% and 82.9% accuracy, beating GPT-5 by 17.8 and 10.7 points and DeepSeek-R1 (671B) by even more. What stood out: giving GPT-5 optional tool https://t.co/xdmOHeiS8U #AI #DrugDevelopment #HealthcareInnovation #Nospecificcountriesarementionedinthetweet.

How to log and audit models, agents, and AI systems in medicine? @ayushnoori MedLog is a syslog for medical AI. Medicine deploys AI on millions of patients with no systematic record of what these models do, when they fail, or who they benefit or harm most. No standard captures https://t.co/LBgWQgb6rP #MedicalAI #AIEthics #HealthTech #Therearenospecificcountriesmentionedinthetweet.
