   Article was published with completely unrelated content under this title and URL: the page slug, excerpt, meta_description, tags, and FAQ were all genuinely about genetic engineering, but the live title read "How Gravity Functions: From Newton to Einstein's Spacetime" and the article body was entirely about spaced repetition and the Ebbinghaus forgetting curve (SM-2 algorithm, Anki, Cepeda et al. meta-analysis, FSRS), with no genetic-engineering content anywhere.

   Before

   Title read "How Gravity Functions: From Newton to Einstein's Spacetime" but the article body was entirely about spaced repetition: "...Hermann Ebbinghaus's forgetting curve... the SM-2 algorithm underlying Anki... Cepeda et al.'s meta-analysis of optimal spacing intervals... modern FSRS scheduling..." with no mention of Newton, gravity, relativity, or Einstein anywhere in the body.

   After

   Title now reads "How Genetic Engineering Works: CRISPR and Gene Therapy Explained" and the body genuinely covers genetic engineering: "...restriction enzymes enabled Boyer and Cohen's 1973 recombinant DNA... Jinek, Chylinski, Fonfara, Hauer, Doudna and Charpentier's 2012 Science paper described the CRISPR-Cas9 mechanism... Casgevy became the first CRISPR-based therapy approved by the FDA, on December 8, 2023, for sickle cell disease..."

   Why: A content-management bug resulted in an unrelated spaced-repetition/forgetting-curve article being published under this page's title and URL, even though the slug, excerpt, meta_description, tags, and FAQ were already genuinely and correctly about genetic engineering. The wrong title and body were replaced with original, verified CRISPR/gene-therapy content. This supersedes the SUPERSEDED note left on contribution 561 (a minor citation fix that lived inside the old misplaced spaced-repetition text and no longer appears on the page); this new contribution documents the full content-swap correction itself. Verified live: the page title and body now match its slug and topic.

   Third author is Stershic (2015), not 'Stencil'.

   Before

   study by Rohrer, Dedrick, and Stencil, students who interleaved

   After

   study by Rohrer, Dedrick, and Stershic, students who interleaved

   Why: SUPERSEDED. Post 1065 (slug how-genetic-engineering-works) previously had its title AND entire body content swapped with unrelated material (a spaced-repetition/Ebbinghaus-to-FSRS article) due to a content-generation bug. The Rohrer, Dedrick, and Stershic (2014) citation this contribution corrected (misspelled as 'Stencil') lived in that misplaced spaced-repetition text, which has now been fully removed and replaced with a genuine, original genetic-engineering/CRISPR article (restriction enzymes, recombinant DNA, CRISPR-Cas9 mechanism, Casgevy's December 2023 FDA approval, base/prime editing, somatic vs germline editing, GMO safety consensus). The before_text/after_text below no longer appear anywhere on the live page. Title, meta_title, and content now correctly match the genetic-engineering topic as of 2026-07-18. Recording as superseded rather than deleting, to preserve the contribution history.
