What "newest" means here

The most recent study in this library is dated 2026-11-01 (Paths of Aging Minds: Health Journeys of Older Adults with Mild Cognitive Impairment). This is our summary library, not a news wire — it is added to in batches, so the newest entry may not be the newest paper published anywhere.

Entries are sorted strictly by publication date, newest first. 26489 of the 27380 entries carry a full day-level date. 65 have no date recorded at all and are placed by publication year, at the start of that year; those are marked "no date recorded" below so you can see where the ordering is a best effort rather than a fact.
