Researchers say this reverses previous assumptions that organ aging is fixed and irreversible. The result may reshape how donor organs are matched and could inform future research into slowing organ aging.","why":"New research suggesting transplanted organs can biologically reverse aging challenges long-held assumptions about organ age and transplantation.","tone":"positive","entities":["ScienceAlert","heart transplant recipients","older heart donors"],"summarized_at":"2026-10-04T19:21:11.040833Z","meta":{"via":"scan","lang":"en","term":"biology","source":"ScienceAlert","published":"Sun, 04 Oct 2026 18:11:40 GMT"},"nw":null,"promo":null,"kind":null,"importance":null,"hidden":false,"hide_reason":null,"judged_at":null,"title_en":"Old Donor Hearts Grow Biologically Younger in Younger Recipients","section_name":"Science","category_name":"Biology","timeline":[{"captured_at":"2026-10-03T19:12:24.764997Z","rank":11,"volume":null},{"captured_at":"2026-10-03T20:35:28.556031Z","rank":10,"volume":null},{"captured_at":"2026-10-03T21:58:17.506132Z","rank":12,"volume":null},{"captured_at":"2026-10-03T23:20:23.135627Z","rank":10,"volume":null},{"captured_at":"2026-10-04T00:42:56.632260Z","rank":7,"volume":null},{"captured_at":"2026-10-04T02:05:38.769086Z","rank":4,"volume":null},{"captured_at":"2026-10-04T03:27:36.919174Z","rank":6,"volume":null},{"captured_at":"2026-10-04T04:49:57.518208Z","rank":8,"volume":null},{"captured_at":"2026-10-04T06:11:57.737197Z","rank":8,"volume":null},{"captured_at":"2026-10-04T07:34:39.512826Z","rank":7,"volume":null},{"captured_at":"2026-10-04T08:57:02.443061Z","rank":8,"volume":null},{"captured_at":"2026-10-04T10:19:01.153355Z","rank":8,"volume":null},{"captured_at":"2026-10-04T11:41:07.880777Z","rank":4,"volume":null},{"captured_at":"2026-10-04T13:03:22.374666Z","rank":5,"volume":null},{"captured_at":"2026-10-04T14:25:03.977331Z","rank":7,"volume":null},{"captured_at":"2026-10-04T15:47:55.213259Z","rank":5,"volume":null},{"captured_at":"2026-10-04T17:09:48.802402Z","rank":5,"volume":null},{"captured_at":"2026-10-04T18:32:30.289286Z","rank":6,"volume":null},{"captured_at":"2026-10-04T19:54:50.625773Z","rank":5,"volume":null}],"posts":[{"platform":"news","url":"https://news.google.com/rss/articles/CBMiqAFBVV95cUxQd3hIQk1TUERGMm5DenNaSUJzUDcxVzdYQVRSVFd2TnI3b2tiMHE0bE9OR0NjbnVVNnNkQ29uWmdwZExJdHZqa29RTEk0TU93R3QyTFFSRmVrZ2l5ZTVTTjVsM0lrWjZQSGNZei1fMXllV3Y1c25WLTRiOXA4LVo3X05OTWVFUTZHMlFHNUJxazg1YnBHVmdJdHl6NDJzckNkZS0ydUdBcHA?oc=5","author":"ScienceAlert","title":"Old Hearts Become Biologically Younger When Transplanted Into Younger People","snippet":null,"posted_at":"2026-10-03T18:02:30Z","likes":null}],"elsewhere":[],"window":"7d"}}
