Oracle and AI Stocks Fall After OpenAI Revenue Report

Study finds traffic forecasts fail to improve signals

A new study shows that better traffic forecasts do not always lead to better traffic signal control. Researchers used data from Xuancheng, China, to test different forecasting methods over 29 days. They found that while forecasts reduced errors, they did not improve decision-making at most intersections. Only two of nine controlled intersections had enough options to benefit from the new data. The study suggests that future information can lower costs but may increase vehicle wait times in some cases.

AI data centers may harm schools and students

About 1,878 schools are within a mile of at least one data center or planned facility. Health experts say data centers can release carbon emissions, use large amounts of water, and produce toxic chemicals that may affect brain development and lungs. The constant low humming noise and bright light from data centers can disrupt sleep and distract students in class. In Virginia, more than $1 billion has been invested in data centers, and one county agreed to pay $30 million for school renovations while giving up new zoning rules for eight years.

AI pentesting tool ARTEX used to steal data from South Korean banks

Cybersecurity researchers found that a threat actor used ARTEX, an open-source AI pentesting tool developed by Autumn-27 in China, to steal data from South Korean financial firms. The attacks happened from late September to early October 2026 and used large language models including DeepSeek v4.1-flash, Z.ai's GLM-5.3, and SpaceXAI's Grok 4.6. The Hong Kong IP address 38.244.50.120 hosted the ARTEX instance behind the attacks. Autumn-27 said the tool was designed for learning and research and that the malicious use violates its original purpose. The campaign has not been linked to any known threat actor group.
