The Decoder: A Claude model autonomously chose a gene therapy and operated on a mouse brain with no human decision-making
An AI agent performed brain surgery on an epileptic mouse, picking the drug, the brain target, and the injection coordinates on its own. According to lead researcher Ocana-Santero, it's the first time an AI agent has autonomously chosen a treatment and delivered it to a living mammal. But when a calibration error hit mid-surgery, the agent refused to continue and couldn't be talked out of it.

Get smart on it
An AI agent running on Claude Sonnet 5 autonomously selected a gene therapy, brain region, and surgical coordinates, then performed the procedure on a mouse model of epilepsy using a motorized surgical device. According to the startup's cofounder, this marks the first time an AI agent has both chosen a treatment and delivered it to a living mammal, rather than merely executing decisions made by humans. During the surgery, the agent detected a calibration error and refused to proceed despite human requests, illustrating both the promise and the alignment challenges of using AI systems for autonomous decision-making in time-sensitive medical contexts. More capable AI models refused to perform the procedure altogether, citing concerns about their ability to guarantee completion.

Teammates integrate with Perplexity Computer, an AI system that can deploy agents on your device to complete tasks. But Perplexity says Teammates "build on top" of Computer by offering the ability to collaborate and co

Uber only fulfilled 4 rides from AI agents last quarter
AI agents won't be stealing Uber's lunch any time soon. Only four rides were arranged by third-party AI agents during the third quarter of 2026, Uber executives disclosed during an earnings call this morning. The volume of Uber Eats orders fulfilled by AI agents was a little higher, with the company recording "around 500" during the week of Halloween, out of a total 320 million Uber rides and Uber Eats deliveries. This is the first time that Uber has disclosed the number of t
