"Decade-Long Alzheimer's Study Retracted by Ex-Stanford President Amid Controversy"

Marc Tessier-Lavigne, a prominent neuroscientist and former Stanford president, has retracted a significant Alzheimer's research paper from Nature after a decade of resistance. The retraction follows the discovery of image anomalies and biostatistical errors, although Tessier-Lavigne denies falsification of data. This is his fourth retraction in recent months, amidst a Stanford-sponsored investigation confirming a pattern of falsified research in labs he oversaw. The paper, once thought to be a breakthrough in Alzheimer's treatment, was also used by Genentech in negotiations to increase the company's valuation during its acquisition by Roche. Concerns about the research's reproducibility and integrity have been ongoing since 2012, with recent developments leading to the retraction.
