Case log

  1. FoundFound on 2010 in science: the citation is live and nothing near it mentions the retraction.
  2. ReviewedRead by hand (2010 in science). Science retracted the arsenic-life paper in July 2025 because its results could not be reproduced. The 2010 entry can stay as history, but it still reads as an established discovery.
  3. Note postedNote posted on the talk page of 2010 in science. See the note.

A zombie is not an accusation. Some articles cite a retracted paper to discuss it, and some retractions don't touch the cited claim, which is why a person reads every case. How we decide · How to contest a case
