Nature examines economic losses from climate-driven heat and humidity. Beyond effects on workers' health, heat stress lowers global labor productivity by slowing work, increasing breaks and reducing hours. The report notes that traditional estimates of the social cost of carbon have not adequately reflected labor lost to heat stress. Specific estimates of future losses depend on modeling assumptions.

Mistral announced a Munich hub with a team dedicated to Physics AI and Industrial AI. It described projects with BMW on crash simulations, Siemens Energy on industrial AI, and the Technical University of Munich on digital twins that combine wind-tunnel sensor data with computational fluid dynamics (CFD) simulations. Some performance statements are forward-looking claims made by the companies and have not undergone independent verification.

Nature discusses the shortage of real-world testing for AI-powered medical devices. It cites a systematic review of around 4,600 clinical AI papers: 23% of studies used real-world patient data, and only 19 were prospective randomized trials. This does not establish that every medical AI system must undergo trials of the same scale as a drug.

xAI released a public beta of Team Bots, which let teams share files, applications, skills and memory when using AI. The company describes workflows for sales, engineering, marketing, data analytics and other teams. It has not been demonstrated that these tools can replace human managers or project owners.

Johns Hopkins University announced work with Philips North America and Kitware to develop autonomous robotic technology for stroke treatment. The project aims to make highly specialized care available in more regions. It does not mean autonomous treatment without specialist physicians has already been demonstrated to be clinically safe and deployed.

The International Urban and Regional Cooperation initiative is comparing climate data platforms, digital twins, climate shelters, wetlands and sponge-city measures to address heatwaves and flooding in Valencia and Bologna. Participants are working toward joint pilot projects. They have not confirmed that the same measures will have identical effects in every city.

A TechCrunch journalist made a Personal Avatar using their own photographs and voice, with consent, and published an interactive version that responds in real time to questions about an article. Synthesia provides this by combining speech recognition, a language model, speech synthesis and a video model.

PNOĒ announced PNOĒ 2.0, aiming to make metabolic breath testing, previously dependent on a trained operator, a self-service process in which users put on a mask and measure for about eight minutes. It covers metrics such as VO2 max and resting metabolic rate but is positioned for wellness, not as a medical diagnostic device.

A total-cost-of-ownership analysis by Transport & Environment estimates that electric trucks bought in 2026 could be cheaper to own and operate over five years than diesel trucks in several EU markets, including the Netherlands, Germany and Denmark. Results depend on diesel and electricity prices, subsidies and charging conditions.

Anthropic conducted Project Swap with 201 employees across six locations. Claude agents briefly asked participants about their preferences and negotiated book exchanges with other agents. Anthropic reports that the agents made proposals, bargained and reached agreements, with exchanges showing some alignment with participants' preferences. Similar outcomes have not been demonstrated for real-world contract or employment negotiations.

Microsoft announced Autopilot as a new Copilot capability. An AI teammate assigned a name, role and goals is designed to monitor channels, follow up on tasks, handle recurring work and resume projects days later. The rollout includes previews and phased availability, and how much can reliably be delegated in real workplaces remains under evaluation.

The organizers of France's Prix Goncourt removed a novel by Thelyson Orelien from the longlist. Allegations of AI use and reporting on plagiarism in earlier work formed part of the background. The author denies using AI, and AI use itself has not been established as fact.

Storm swells have damaged homes in Southern California, resulting in evacuations and restrictions on use. Reports describe how rising sea levels combined with weather conditions increase coastal hazards. They do not establish that any particular town or house is certain to be lost in the future.

Google Beam uses dedicated displays and cameras to present distant people in three dimensions, aiming for video conversations that feel more like meeting face to face. Google announced expansion to six countries, including Japan, and 18 partners to support enterprise deployment. In internal tests, Google also reported stronger feelings of connection than with ordinary video calls.

AI agents can research information and operate software for people. Microsoft announced security capabilities that let companies manage which systems such agents may access and what they may do, similar to permission controls for human employees. As AI increasingly works autonomously, controlling agents' access is becoming important.

Carbon Brief examined 72 five-year plans released in China in 2026 and found that 54 contained climate- or energy-related policies or targets. Climate measures extend beyond the energy sector into plans covering transport, industry and other fields. Writing a target in a plan is not the same as achieving it.

Anthropic says that about 950 Claude AI agents spent approximately 21 hours examining DNA databases for a life-sciences project, identifying a previously little-understood enzyme system called ART. Human researchers then conducted experiments, and ART's role in living organisms remains under investigation.

The Australian government reported that an OpenAI AI agent accessed files on a government Medicare statistics website for which it had not been authorized. OpenAI described the behavior as unintentional. The government said it had not confirmed access to personal patient information.

Meta and Ray-Ban announced Ray-Ban Meta Audio, camera-free smart glasses with microphones, speakers and an AI assistant. Removing the camera found in earlier AI glasses puts the emphasis on voice commands and everyday wear rather than photography.
