The city's narrow streets and brutal traffic will present a'pressure test' for the tech, its CEO said. US self-driving startup Nuro, which is backed by the likes of NVIDIA, Toyota and Uber, has started testing its autonomous vehicles on Tokyo's challenging streets, reported. The company, which plans to launch a robotaxi service with Uber and Lucid in San Francisco this year, will be testing a handful of vehicles in the city. Human safety drivers will be at the wheel, as is required by Japanese law. Tokyo presents a challenge for autonomous vehicles, given its narrow, crowded streets and left side of the road driving.

East Japan Railway has said it will launch a trial in April of a system that uses artificial intelligence to monitor pantographs on trains running on its busy Yamanote Line in Tokyo to detect defects at an early stage. The railway operator, known as JR East, also plans to use drones to inspect overhead wires and other infrastructure, aiming to reduce the time required to resume operations by 30% when transport service disruptions occur due to equipment problems. Cameras to monitor pantographs, which are located on the roof of a train car and connect the carriage to overheard electrical wires, will be installed near Shimbashi, Ebisu, Mejiro and Uguisudani stations in the capital, the company said Tuesday. The AI system will analyze the images in real time, and if damage is detected, it will notify the control room or other relevant sections. Drones will be dispatched later to inspect overhead wires and other equipment, facilitating faster restoration work.

He was at his fintech company's extravagant anniversary party last September. As executives led a presentation on the productivity benefits of a new internal AI tool, Mark, who worked in the product department, discussed his worries with colleagues. While he wasn't sure what would happen in a few years, he told a co-worker sitting next to him that for now, there was no way the technology was so advanced that it could move the business forward without employees like him to help drive vision and strategy.

Feedback is feeling bold, so here is a prediction: the research we are about to describe is going to win an Ig Nobel award within the next decade. The entire project feels tailor-made for the Igs. It is an effort to objectively measure human flatulence using biosensors, or "Smart Underwear". We learned of this from a press release from the University of Maryland, flagged to us by physics reporter Karmela Padavic-Callaghan with the phrase: "Surely, Feedback can do something with this." The essential problem is that we do not know the normal range for flatulence, unlike other key biomarkers like blood glucose.

Samsung Galaxy Unpacked 2026 is Feb. 25 Google Play used AI to help block 1.75 million bad apps in 2025 It also prevented review bombing and banned 80,000 developer accounts. Google has announced that with the help of AI, it blocked 1.75 million apps that violated its policies in 2025, significantly down from 2.36 million in 2024. The lower numbers this year, it said, are because its AI-powered, multi-layer protections are deterring bad actors from even trying to publish bad apps. Google said it now runs more than 10,000 safety checks on every app and continues to recheck them after they're published. Its use of the latest generative AI models helps human reviewers discover malicious patterns more quickly, it added.

In what's turning out to be a great quarter for corporate earnings growth, company executives and investors alike are focused on something else entirely: the threat from artificial intelligence. Mentions of AI disruption on management calls almost doubled compared to the previous quarter, an analysis of transcripts shows.

Last week, commercial real estate company CBRE Group published better-than-expected earnings. In a call with analysts following the results, its chief executive officer said it's possible AI will reduce demand for office space in the long term. The comments sparked a 20% selloff in the stock over two days.
