Tesla workers resist wearing suits to train Optimus robots
Tesla asked factory staff in Texas and California to record their motions for robot training, but some workers pushed back, fearing the humanoids could replace them.
Insurers say hospital AI coding added $942 million in costs
The Blue Cross Blue Shield Association says hospitals’ use of AI tools to prepare insurance claims was linked to $942 million in extra healthcare spending over two years. Its analysis found more patients coded as having complex conditions, without evidence of matching changes in care.
Bilingual AI audiologist beats human experts in blind simulation study
A research team reported that their AI system, built from a large language model and a rule‑based playbook, outperformed 17 practising audiologists on 58 simulated cases in English and Chinese.
SlideLab uses AI agents to build and test research presentations
A new arXiv paper describes a system that turns research papers into slide decks and checks whether audiences can follow them. Its authors say people preferred its presentations to those from other systems on 77% of papers in a blind study.

LAVOIR adds smart follow‑up questions to single‑pass AI decisions
The new model improves answer accuracy by up to 14 points while asking fewer than one question per chat, according to a Sep 28 arXiv paper.
Startup licenses video game data to train AI world models
British startup Worldmodeldata is turning video game footage and player inputs into training data for AI systems that need to act in the physical world. The company says it has licensed nearly 1 million hours of game data.
OpenAI Says AI Agents Solved a Long-Standing Math Problem
OpenAI says thousands of AI agents produced a solution to the Navier-Stokes existence and smoothness problem, a puzzle mathematicians have studied for decades. The result is mathematical, not an engineering breakthrough, and some researchers worry that brute-force proof-making could leave people with less understanding.
OpenAI’s math advisory group faces a trust problem
A group of nine mathematicians says it is independent of OpenAI, despite forming after the company approached some members. Its first challenge may be helping handle more than 100 mathematical results OpenAI says it has not yet released.
Anthropic’s AI biology finding raises questions about scientific discovery
Anthropic says 950 Claude agents identified a previously uncatalogued pattern near a known enzyme. Biologists disagree over whether finding that pattern counts as a scientific discovery.
