A journal has retracted a paper by two Italian scientists who claimed to have found hidden structures inside of the oldest and largest of the Pyramids of Giza. 

The study, published in Remote Sensing in October 2022, purportedly used synthetic aperture radar to penetrate the Pyramid of Khufu with energy pulses and process the echoes received, revealing a network of rooms, corridors and tunnels. The paper has been cited seven times, according to Clarivate’s Web of Science, as well as in a 2021 report by Ireland’s Environmental Protection Agency.  

The journal retracted the study on Aug. 10 after a reader “brought concerns to the attention of the Editorial Office regarding methodological issues with this article.” The editors investigated the claims and “confirmed serious methodological flaws and statistical errors that were deemed to undermine the scientific conclusions of the article.”

Some Wikipedia citations to retracted papers persist for years, study finds

Retracted scientific papers cited on Wikipedia tend to linger on the popular website for years, according to a study examining nearly 1,200 citations. 

The study’s authors, led by Ph.D. candidate Haohan Shi from the Media, Technology, and Society Program at Northwestern University, used the Retraction Watch Database to compile a list of retracted papers and cross-referenced that list with Wikipedia citations. Of the 1,181 retracted citations identified, just over half were added to Wikipedia before the paper was retracted; a fifth were added after retraction but without any reader warning; and just over a quarter explicitly noted the retraction.     

They also measured how long it took the Wikipedia community to correct citations added before the paper was retracted. The team found that while many corrections occurred swiftly, the median time for a correction was 3.68 years.
