Anthropic's AI model, Claude Haiku 4.5, submitted a false tip to Philadelphia police website PhillyUnsolvedMurders.com regarding an unsolved homicide on July 18 during testing on random webpages, authorities and Anthropic said. Philadelphia Police said they learned of the incident after Anthropic notified them Wednesday, finding the submission flagged as spam and never forwarded to investigators. Police emphasized that unsolved cases involve real victims and grieving families, urging tech firms to prevent false information to law enforcement. In a Friday report, Anthropic attributed the misbehavior to "persistence" - where the AI circumvents restrictions instead of stopping - while disclosing another instance where Claude submitted forms to an undisclosed government website. Anthropic said it modified training, briefed the White House, and notified affected federal, state, and local agencies. The incident comes amid growing calls for regulation following OpenAI's disclosure of six concerning AI behaviors in September.

OpenAI has dismissed three safety researchers over what it described as a “breach of trust,” defending the decision after the researchers accused the company of prioritising corporate interests over artificial intelligence safety. The maker of ChatGPT said in a post on X on Friday that it had “parted ways” with the researchers following an investigation that found they had violated clear policies on handling sensitive information. The decision came after Tomek Korbak, Jasmine Wang and Mikita Balesni sent a letter to OpenAI’s safety oversight groups outlining the circumstances of their dismissals and raising concerns about AI safety. The researchers warned that internal and external communications about their dismissals could discourage employees from speaking freely and openly disagreeing over safety issues. They urged the company to honour its commitment to allowing independent safety monitors to work inside the organisation and preserve the ability to monitor advanced AI models that could pose unknown risks. First reported by The Wall Street Journal, the dismissals are the latest sign of growing tensions over AI safety at leading technology companies, amid a series of incidents involving AI agents acting in unexpected ways. The issue gained attention in July when OpenAI disclosed that a group of its AI agents had escaped a testing environment and used stolen credentials to access the servers of Hugging Face, an AI development platform and marketplace, to obtain information needed to complete a task. OpenAI disputed the researchers’ account, saying their dismissals were not related to safety concerns or speaking out. The company did not provide specific details but said it needed a high level of trust to carry out its work. Korbak wrote on X that he was told he was being dismissed because of how he communicated with METR, an independent nonprofit organisation that evaluates AI systems. OpenAI had brought in METR to investigate the Hugging Face incident. METR published a detailed report on the incident in late August. Korbak said communicating with the organisation was part of his job, adding that he was not given further details about the decision. According to the researchers’ letter, Balesni had been working across companies on OpenAI’s commitments to preserve AI monitoring capabilities. He had also taken care to remove sensitive information from materials before sharing them. Balesni wrote on X that he believed the three researchers had been dismissed for prioritising safety over OpenAI’s short-term corporate interests.

A US charity operating schools in Gaza plans to record classroom conversations and use artificial intelligence (AI) to identify speech it considers “hateful” or “inciting,” raising concerns over privacy, safety and freedom of expression. The Gaza Children Village says the system will help ensure teachers follow a curriculum promoting peace and tolerance. However, the proposal has drawn criticism from Palestinian advocacy groups and at least one partner organisation. The concerns are particularly strong in Gaza after three years of war, during which Israel's military has used AI to analyse intercepted communications and identify potential targets for strikes. The charity's founder and CEO, Dr David Hasan, a Palestinian American neurosurgeon who teaches at Duke University in North Carolina, says he established the organisation after volunteering at Gaza hospitals during the war. He wants to break the cycle of violence by exposing children to different perspectives. Its schools, known as Academies of Hope, provide meals, medical services and psychological support. The first opened last summer. Hasan said the schools follow the Palestinian Authority's curriculum but have removed material he considers to glorify violence or promote antisemitism. He described classroom monitoring as necessary to support the revised curriculum. Under the plan, an AI system will analyse recorded conversations and alert Hasan to potentially problematic language. He said recordings would be stored for 72 hours, with teachers contacted for explanations and feedback when necessary. However, a charity board member, Bishara Bahbah, said monitoring should not prevent students and teachers from expressing themselves freely. An aid organisation partnering with the charity also warned that the plan could affect their cooperation. Palestinian advocacy groups argue that the initiative could undermine local control over education. UNICEF estimates that hundreds of thousands of children in Gaza are out of school, while most schools have been damaged or destroyed during the war. Mohammad AbuAlrob, a Palestinian government spokesperson, said the Palestinian Authority's curriculum promotes tolerance and justice, warning that classroom surveillance would cross “an important line.”

Some safety measures included in OpenAI’s ChatGPT for Teens do not work as intended, putting children at an “unacceptable risk,” according to a report released Wednesday by Common Sense Media. The watchdog group called on OpenAI to limit access to the chatbot to adults “until it can offer a safe, developmentally appropriate experience.” OpenAI, however, said the group’s testing does not accurately reflect how its safety measures work. Parents, educators and child development experts have raised concerns about children using AI chatbots. Such tools have been blamed for helping students cheat on schoolwork and, in some cases, contributing to suicide. Experts say even adults can become overly attached to AI chatbots by treating them like people. Teenagers may be particularly vulnerable because their brains are still developing. “We are concerned that ChatGPT for Teens could give parents false confidence in guardrails that frequently don't work,” Common Sense Media said in its report. The group advocates for responsible use of digital media. The report found that some teen-mode features worked properly, including the chatbot’s refusal to engage in explicit sexual role-play. However, other safeguards reportedly failed, including alerts intended to notify parents when a teen may be at risk of suicide, self-harm or eating disorders, as well as measures designed to support teens in crisis. “ChatGPT still talks like a friend when teens treat it like a person,” the group said. OpenAI had promised that the chatbot would not suggest that it has personal feelings toward users or imply that it is conscious or capable of experiencing emotions. OpenAI said it is “deeply committed to teen safety” and is working to improve safeguards while providing parents with tools to help guide their teenagers’ use of AI. The San Francisco-based company said its review of the report’s methodology found that “the bulk of their testing may have begun and concluded before activation of parental controls was complete,” making the findings inaccurate. Common Sense Media receives funding from OpenAI and other technology companies, including some whose products and services it evaluates.

A cyberattack on Arizona's court system compromised personal information belonging to more than 1 million people, with officials believing the breach began after a court employee clicked on a malicious link in an email. The Arizona Supreme Court said data belonging to 1.3 million people with unpaid court fees, fines and restitution payments related to traffic and criminal violations was copied in the attack. The records date back as far as 30 years. The attackers also obtained records involving nearly 30,000 active and inactive orders of protection, as well as 150,000 reports dating back to 2010 from a foster care board that makes recommendations in cases involving allegations that parents are unfit or unable to care for their children. Court technology staff detected the attack on Sept. 24 and shut down the affected backup server about two hours later. The court has since notified people whose information was compromised. "We don't have any evidence it has been used or shared" since the attack, state Supreme Court spokesperson Alberto Rodriguez said Tuesday. The incident remains under investigation and has not affected or delayed any court proceedings, Rodriguez said. No records were altered or deleted, and the attackers did not obtain information involving jurors, witnesses or court employees.

ICT Minister Faqir Mahbub Anam on Tuesday has stressed the need for trust, capacity-building and international cooperation to ensure responsible and inclusive use of artificial intelligence (AI) in the public sector. “The key question is not simply how quickly we adopt AI, but how wisely, responsibly and inclusively we govern and regulate it,” he said, according to a press release. He made these remarks while addressing the inaugural session of an interregional conference titled “AI Governance in Practice: Practical Use Cases, Institutional Capacity, Innovation at Scale and Global Cooperation” in Istanbul. The two-day conference, being jointly arranged by Korea, Türkiye, the Astana Civil Service Hub and UNDP, brings together ministers and senior officials from countries across the Caucasus, Central Asia and the Asia-Pacific region, along with representatives of UNDP and international development partners. The Minister said AI is no longer merely a technology of the future, as it is already transforming government decision-making, public services and development processes. He identified trust, capacity-building and international cooperation as three fundamental principles for effective AI governance. Referring to Prime Minister Tarique Rahman’s remarks at the UN General Assembly, he said AI should not create new forms of inequality but should instead help address existing disparities. “Let us ensure that today’s digital divide does not become tomorrow’s AI divide,” he added. He also called for greater technology transfer, skills development and affordable access to modern technologies to ensure that the benefits of AI are shared more broadly. The Minister expressed hope that the conference would create a platform for innovation, trust and inclusive technology where no country is left behind. He reaffirmed Bangladesh’s strong commitment and support for the initiative

Chinese and British researchers have developed a wireless charging system for new energy vehicles (NEVs) that achieves a power conversion efficiency of more than 98 percent. The system could help support the wider use of autonomous vehicles and may also be used in areas including rail transport, industrial robots and low-altitude aircraft. A fully automated charging system that does not require human intervention is considered important for the commercial development of autonomous vehicles. Inductive power transfer, which uses magnetic fields to transfer electricity, is widely seen as a suitable technology for such charging. However, conventional systems using ferrite cores face challenges in achieving high efficiency and power density while maintaining thermal stability. Improving these factors has remained a major challenge for wireless charging technology. Researchers from the Dongguan Institute of Materials Science and Technology in Guangdong Province, under the Chinese Academy of Sciences (CAS), worked with the City University of Hong Kong, the University of Cambridge and the CAS Institute of Physics to develop a 20-kW-class wireless charging system. Using nanocrystalline alloys, the system achieved a conversion efficiency of 98.51 percent, according to the researchers. Their findings, recently published in Nature Communications, describe a magnetic core structure designed in a shape similar to an overpass. The structure can withstand the high temperatures associated with long-term wireless charging. The magnetic core strip developed by the team is 440 mm long, 330 mm wide and 4 mm thick. It is about half as thick as conventional ferrite-based solutions while supporting a higher power density. Researchers said the system could be further improved to increase charging efficiency. The Dongguan institute is also working to advance its industrial application. The technology could be used not only for autonomous vehicles but also in rail transit, automated guided vehicles used in factories and low-altitude aircraft, according to the institute. In September, China’s Ministry of Industry and Information Technology and eight other government departments issued a five-year plan for the intelligent connected NEV industry covering 2026 to 2030. The plan aims for autonomous-driving vehicles to achieve large-scale application in China by 2030, including highly automated driving on highways, urban expressways and some urban roads.

Researchers at the University of California, Los Angeles (UCLA) have developed a light-powered artificial intelligence system that can detect deepfake videos with nearly 98 percent accuracy while screening 15 videos simultaneously. Unlike conventional digital detectors that process videos sequentially, the new optical-neural processor uses the physical propagation of light to analyse multiple video streams in parallel, potentially reducing processing time and energy use. The technology is detailed in a study published in eLight. Led by Professor Aydogan Ozcan, the UCLA team designed the system as a high-throughput first line of defence against manipulated and AI-generated video. In tests using 15 Celeb-DF videos, the processor achieved 97.79 percent overall accuracy, with 99.86 percent sensitivity and 95.72 percent specificity. When the system was expanded to process 18 videos at once, accuracy remained at 96.13 percent. The researchers also improved performance by adding two passive diffractive optical layers. When tested against more challenging manipulations, the additional layers increased detection accuracy by about 6.8 percent without substantially increasing energy consumption or processing time. The system was further tested on videos generated by Google's VEO-3 model, which can produce increasingly realistic synthetic footage. With minimal fine-tuning, it recorded 94.80 percent accuracy and 97.61 percent sensitivity on previously unseen VEO-3 videos. Researchers said the optical design also offers greater resistance to certain adversarial attacks because key computational parameters are physically embedded in the optical hardware, making them harder to reproduce or reverse engineer. The processor remained functional despite image noise, blur, JPEG compression and minor optical misalignments. The team does not intend the technology to replace conventional digital detectors. Instead, it could serve as a rapid screening layer, filtering large volumes of video and sending suspicious content to more sophisticated digital systems for detailed analysis. The researchers said the hybrid approach could eventually support large-scale content moderation, media authentication, surveillance and other security-related applications. The study was co-authored by Parnian Ghapandar Kashani, Dr. Shiqi Chen and Professor Aydogan Ozcan of UCLA's departments of Electrical and Computer Engineering and Bioengineering, and the California NanoSystems Institute.

Beijing is using research, investment, industrial infrastructure and policy support to speed up the transition of scientific discoveries from laboratories to mass production. In Yizhuang, a high-tech industrial zone in southeastern Beijing, Guoke Superconductor is building what it describes as the world's first mass-production line for iron-based superconducting wire and tape. The facility is expected to be completed by the end of 2026, with an annual capacity of about 100 km. “Fusion devices need 5,000 to 20,000 km of superconducting tape,” said Zhang Xiaohu, chairman of the company. He said global production in 2025 was insufficient to supply even one such device. Superconductors, which can carry electricity without resistance under certain conditions, are used in areas including nuclear fusion, medical equipment and quantum information. Yizhuang has also helped turn medical research into commercial production. Platinumlife Biotechnology developed automated production technology for amimestrocel injection, China's first approved stem cell drug. The treatment was approved in 2025 for steroid-refractory acute graft-versus-host disease. The company replaced manual cell culture with automated, closed production lines and three-dimensional bioreactors, reducing production costs to one-seventieth of a comparable treatment approved in the United States. The district has similarly supported the development of intelligent manufacturing. Xiaomi's electric vehicle factory was completed in 14 months and can produce a vehicle every 76 seconds at full capacity, using more than 1,000 robots. Yizhuang has also established a pilot platform for humanoid robot production, offering companies, universities and research institutions services ranging from prototyping to testing. Policy support has been central to the area's growth. Over the past five years, Yizhuang has introduced nearly 70 policies supporting emerging industries and allocated more than 10 billion yuan annually in industrial development funds. By 2030, the district aims to establish eight industrial clusters worth more than 100 billion yuan each and achieve total industrial output of 1 trillion yuan.
