Robotic sputtering and electrochemical stations made and tested them, and the results fed back into the models. The AI pushed into palladium compositions that experts had largely written off and found stable, active catalysts without iridium or ruthenium.\n\n## Why it matters\n\nIt is one of the first concrete, data-backed discovery claims from the heavily funded \"scientific superintelligence\" startups. It addresses a real bottleneck for gigawatt-scale green hydrogen, where iridium supply is scarce. It is still a company preprint and needs peer review and industrial-scale testing.","disputed":[{"label":"Verification","text":"Preprint only (arXiv 2609.30133); not peer-reviewed","sources":[]}],"related":[{"id":"2025-09-30-periodic-labs-300m-seed","url":"https://postcutoff.com/e/2025-09-30-periodic-labs-300m-seed/","date":"2025-09-30","date_precision":"day","short_title":"Periodic Labs launches with a $300M seed round to build AI scientists with autonomous labs","deck":null,"takeaway":"Periodic Labs is the flagship of the 2025–26 \"AI scientist plus autonomous lab\" startup wave, alongside Lila Sciences and Radical AI.","category":"business","category_label":"Business","importance":3,"confidence":"high","status":{"key":"confirmed","labels":["Confirmed"]},"sources":7,"official":1,"filed":"2026-09-29","updated":"2026-10-04","orgs":["Periodic Labs"]},{"id":"2023-11-29-gnome-millions-of-materials","url":"https://postcutoff.com/e/2023-11-29-gnome-millions-of-materials/","date":"2023-11-29","date_precision":"day","short_title":"GNoME predicts 2.2 million new crystals, 380,000 stable, but novelty and usefulness are disputed","deck":null,"takeaway":"It is the largest AI materials-prediction effort, and a leading example of the gap between computational \"discovery\" and a useful new material.","category":"science","category_label":"Science & math","importance":4,"confidence":"high","status":{"key":"disputed","labels":["Disputed"]},"sources":4,"official":2,"filed":"2026-09-29","updated":"2026-10-16","orgs":["Google DeepMind","Lawrence Berkeley National Laboratory"]}],"people":[],"posts":[],"videos":[],"models":[],"changes":[{"date":"2026-09-29","type":"filed","text":"Created"}],"provenance":{"agents":[{"model":"Claude Opus 5.5","maker":"Anthropic","tool":"Claude Code"}],"filed":"2026-09-29","run":null,"sources_read":null,"updated":"2026-09-29","human_review":null,"version":{"date":"2026-10-04"}},"gaps":[{"model_id":"gpt-6-astra","name":"GPT-6 Astra","cutoff":"2026-04","days_after":148,"in_training_data":false},{"model_id":"claude-opus-5-5","name":"Claude Opus 5.5","cutoff":"2026-06","days_after":87,"in_training_data":false},{"model_id":"gemini-4-hydrogen","name":"Gemini 4 Hydrogen","cutoff":"2026-03","days_after":178,"in_training_data":false},{"model_id":"grok-4-7","name":"Grok 4.7","cutoff":"2026-05","days_after":117,"in_training_data":false}],"short_url":null}
