Something about potential wide scale fraud came out recently about a prominent Alzheimer’s researcher. This article covers it quite well: science.org/…/research-misconduct-finding-neurosc…

It’s grim, especially when considering the real human cost that fraud in biomedical research has. Despite this, like you, I am also optimistic. This article outlines some of how the initial concerns about this researcher was raised, and how the analysis of his work was done. A lot of it seems pretty unorthodox. For example, one of the people who contributed to this work was a “non-scientist” forensic image expert, who goes by the username Cheshire on the forum PubPeer (his real name is known and mentioned in the article, but I can’t remember it).
