Out of 110 cloned candidates, it found 60 that neutralized viruses - a 55% hit rate - and 12 broadly neutralizing antibodies, an 11% yield. That beat sequence-based prediction tools and cofolding models tested with the same cloning budget. Five of the discovered antibodies gave mice complete protection against a lethal flu challenge, matching results from MEDI8852, a clinical-stage antibody therapy.\n\nThe bigger finding is what the system learned about where these antibodies come from. It flagged FCRL5+CD27+ atypical memory B cells as a recurring source of broadly neutralizing antibodies and hydrophobic interface enrichment as a shared structural trait across viruses. That pattern held up on viruses the system wasn't trained to target, turning up cross-neutralizing antibodies against human metapneumovirus and HPV-neutralizing antibodies without needing antigen-specific sorting first. If that generalization holds, it points toward antibody discovery that moves faster than the traditional one-virus-at-a-time screening pipeline.\n\nWorth noting: this is a 110-candidate study with mouse data, not human trials, and a generalizable framework claim still rests on one research team's cloning budget. The comparison to MEDI8852 is encouraging, not confirmation this ships as a drug.","[\"ai\",\"antibodies\",\"immunology\",\"drug-discovery\"]","2026-10-05T04:00:00.000Z","2026-10-05T19:49:28.531Z","2026-10-05T19:49:34.494Z","published",null,[],"ai",[24,26,27,28],"antibodies","immunology","drug-discovery",[30],{"name":31,"url":32},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2610.03160",0,{"sections":35},[36,39,43,48,53,58,62,67,71,76,81,86,91,96],{"name":37,"slug":24,"count":38,"latest_published_at":18},"AI",6290,{"name":40,"slug":41,"count":42,"latest_published_at":18},"Security","security",869,{"name":44,"slug":45,"count":46,"latest_published_at":47},"Policy","policy",444,"2026-10-03T15:02:01.000Z",{"name":49,"slug":50,"count":51,"latest_published_at":52},"Deals","deals",323,"2026-10-04T13:00:00.000Z",{"name":54,"slug":55,"count":56,"latest_published_at":57},"Hardware","hardware",204,"2026-10-03T14:50:50.000Z",{"name":59,"slug":60,"count":61,"latest_published_at":18},"Science","science",178,{"name":63,"slug":64,"count":65,"latest_published_at":66},"Consumer Tech","consumer-tech",158,"2026-10-03T03:21:12.000Z",{"name":68,"slug":69,"count":70,"latest_published_at":18},"Dev Tools","dev-tools",98,{"name":72,"slug":73,"count":74,"latest_published_at":75},"Software","software",97,"2026-10-04T10:00:00.000Z",{"name":77,"slug":78,"count":79,"latest_published_at":80},"Startups","startups",92,"2026-10-04T14:36:25.000Z",{"name":82,"slug":83,"count":84,"latest_published_at":85},"Gaming","gaming",53,"2026-10-02T02:50:39.000Z",{"name":87,"slug":88,"count":89,"latest_published_at":90},"General","general",51,"2026-10-05T02:35:01.000Z",{"name":92,"slug":93,"count":94,"latest_published_at":95},"Reviews","reviews",32,"2026-10-02T18:00:00.000Z",{"name":97,"slug":98,"count":99,"latest_published_at":100},"How-To","how-to",7,"2026-10-01T09:00:00.000Z"]
