Researchers reviewed 239 peer-reviewed studies on AI-supported deep-brain stimulation and found a pronounced gap between reported algorithmic performance and clinical readiness. External validation remained rare, evaluations were predominantly retrospective and single-centre, and more than one-quarter of studies used small, high-dimensional datasets with elevated overfitting risk; most systems therefore remained at early-to-intermediate technology-readiness levels.

This is strong negative-side evidence that medical-AI deployment is often constrained less by model capability than by weak generalizability, narrow disease coverage, and insufficient prospective testing.

A review of evidence across cognitive science, education, medicine, and human-factors research finds that fully offloading mental work to AI can weaken the acquisition and retention of the specific skills people stop practicing. The authors distinguish that evidence from broader claims about declining intelligence: effects on foundational abilities such as attention and working memory remain uncertain, while AI used as a collaborator, tutor, or source of feedback can preserve or improve learning.
In a randomized field experiment across a chain of middle and high schools in Turkey, giving teachers a generative-AI support tool reduced students’ intrinsic motivation by 0.11 standard deviations. Average academic performance did not change, but students taught by lower-performing teachers experienced significant declines in both performance and confidence, showing that a tool that makes lesson preparation easier for teachers does not automatically improve the student experience.
The NUS/Harbin-led team identifies a domain-specific form of generative-AI hallucination: molecular candidates can receive strong predicted binding scores while violating basic chemistry or producing physically impossible atomic arrangements. Its DrugRPG framework incorporates chemical-foundation-model priors and differentiable physical constraints during molecule generation, reducing severe steric clashes by 65.4% relative to the reported state-of-the-art baseline and increasing by 28.6% the share of generated candidates meeting combined potency, stability, and synthetic-feasibility criteria.
