One human health check erases semaglutide's behavioral effect in mice, preprint finds
BenSiranosian · x · 2026-10-02
- Olio Labs' bioRxiv preprint ("Schrodinger's mouse") shows that human observation alone can wipe out experimental results in animal studies.
- Two mouse cohorts got semaglutide (0.03 mg/kg, i.p.); one was recorded without inspection, the other got a single visual-only health check.
- In the checked cohort, the semaglutide-induced behavioral phenotype was erased exactly when animals were observed.
- A warning for all human-observation-based animal research: automated, unattended monitoring is preferable.
