Disputed The sentence does appear verbatim for the cited Nature URL in search results, and the Nature page shows the piece was published on 24 February 2026. But the source is a jointly authored Nature Comment: the byline lists 23 named co-authors, including Jean-Claude Manuguerra, so the text is not attributable to Manuguerra alone. Because this platform verifies single-author quotes, this stored attribution is disputed.
