As AI agents gain the ability to execute code, call APIs, and interact with external systems with minimal human oversight, two research teams have published independent frameworks aimed at making those agents safer — one by automatically refining safety rules over time, the other by placing an inviolable enforcement layer outside the agent's own control.
Researchers across multiple institutions published a cluster of artificial intelligence studies this week addressing some of the technology's most consequential applications and shortcomings: optimising urban transport networks, detecting security threats in autonomous vehicle convoys, forecasting dementia progression, accelerating MRI analysis, and — most critically — quantifying how commercial AI systems systematically overcharge speakers of African languages through a structural quirk in how they process text.
Despite recent headline-grabbing achievements in competition mathematics, leading artificial intelligence systems are scoring below 15% on newly developed benchmarks designed to test genuine research-level mathematical reasoning, according to two independent studies published this month.
Two new studies from the same research group cast fresh light on a growing concern in artificial intelligence: whether large language models acting as automated judges unfairly favour their own outputs.
