Beginning in April 2026, Chinese science communicator and academic-fraud investigator Geng Hongwei, known online as Classmate Geng, publicly challenged papers authored by scholars at multiple Chinese universities. The papers appeared in Nature and affiliated Springer Nature journals, including Nature Cell Biology. Geng alleged that the studies contained fabricated data, bringing research-integrity concerns in Chinese higher education to broad public attention on Bilibili and Douyin.
The supplied account does not establish that the alleged fabrication was confirmed by Springer Nature, the universities involved, courts, or regulators, and it names no retractions, disciplinary findings, financial losses, or criminal proceedings. Geng earned biology degrees from Jilin University and pursued a Ph.D. at Beihang University, which he left without completing in 2025. The lasting consequence documented here is heightened public scrutiny of academic oversight and publication review in China; the specific allegations remain unverified.
