FYI - Retracted paper in the NAD field: Nicotinamide Ameliorates Amyloid Beta-Induced Neurodegeneration in Adult Mouse Brain. The editors lost confidence in the findings after "indications" of inappropriate editing & partial duplication

Apparently the authors couldn't (or chose not to) provide the original data that was asked of them. Lesson - keep all original data for decades

AI screening of manuscripts by the corresponding author(s) for duplication or fraud (i) before submission and (ii) by the journal and (iii) by reviewers will make this a thing of the past
