Disputed The quoted sentence appears verbatim in the article text/abstract, and the cited record is for Science 377(6609), dated 2022-08-26. The source also shows this is a multi-author paper led by Jonathan E. Pekar et al., with Lorena Mariana Malpica Serrano listed as one coauthor rather than as the sole speaker/author of the sentence. Because this platform cannot verify a multi-author paper quote as a single-author quote, the attribution to Lorena M. Malpica Serrano is disputed even though the wording itself is real and the source URL contains it.
