Researchers at Rensselaer Polytechnic Institute (RPI) found that leading AI models frequently create impossible protein structures [1][2]. The study, published in PNAS, analyzed tools like AlphaFold2 and RoseTTAFold2 [1]. These models sometimes generate results that defy physical and chemical laws [1][2].

The findings highlight "growing pains" for AI in scientific laboratories [1]. Researchers emphasize that AI-driven biological research still requires physics-based verification to ensure accuracy [1][2]. Without these checks, scientists risk using flawed data in drug discovery and molecular biology [1].
