Author Correction to study on Rh3+-stabilized zeolite catalyst for hydroformylation

Nature issued an author correction to a paper reporting that Rh3+ ions stabilized within a KRh@MFI zeolite catalyze regioselective hydroformylation. Such notices fix errors in the published record rather than announce new findings, so the underlying chemistry is unchanged. It matters mainly to catalysis researchers relying on the paper's accuracy.

OpenAI explains methods for detecting frontier model misalignment

OpenAI published a blog post describing how it detects misalignment in frontier AI models. The post outlines evaluation and monitoring approaches intended to identify risky behavior before deployment. It matters because stronger detection can inform safety practices as advanced models are released.
