The story highlights growing overlap between AI and robotics at the smallest end of engineering.

Indian border guards shot and killed two Pakistani citizens and wounded a third near the India-Pakistan border in Pakistan's Punjab province on Friday, local media reported. According to initial accounts, the civilians had crossed a border pillar when the guards opened fire. The incident risks adding fresh tension between the two neighbours, who regularly report violations along the heavily militarised frontier.

Brian Greene, the Columbia University physicist and science communicator, has stopped teaching the university's Frontiers of Science course after more than a decade in the classroom. Greene, known for his work popularizing string theory and theoretical physics, was a longtime fixture of the core science curriculum, and his departure marks the end of a notable chapter for the course.

Google's Gemini 4 Argon (High) model is being examined in a new analysis that compares its intelligence, performance and pricing.

Readers are weighing its pricing against measured intelligence scores.

A new scoping review published in Frontiers examines how food literacy assessment tools for adults have evolved, including changes in the dimensions they measure and how they have been culturally adapted across different settings. The authors also discuss potential implications for nursing practice, suggesting food literacy could inform patient education and health promotion work by nurses.

A report from the Centre for the Study of Existential Risk lays out what is meant by frontier artificial intelligence and the idea of an intelligence explosion, exploring how rapidly improving AI systems might eventually surpass human capabilities. The piece is drawing attention among readers weighing the technical arguments and the uncertainty around how soon, or whether, such a transition could occur.

OpenAI has replaced its GPT-6 Sol model with an updated GPT-6.1 Sol only seven days after the previous release, according to Artificial Analysis. The new model is described as reaching near-Astra levels of intelligence, and the unusually short turnaround between flagship releases is drawing attention to the accelerating pace of frontier AI competition.

Anthropic's frontier red-teaming report says a widely used open-weight Chinese AI model shows 'Mythos-class' hacking capabilities and that its safeguards are weak. The claim is drawing attention to risks around freely downloadable frontier models and how safety evaluations should be applied to them, with debate expected between Anthropic and the model's Chinese developers.

A new perspective article in Frontiers in Psychology proposes rethinking epilepsy using ideas from theoretical physics, framing seizures through the concept of multidimensional time. The piece suggests that brain activity during seizures might be better understood if time is treated as having more than one dimension. The unconventional cross-disciplinary approach has drawn attention for its ambitious attempt to connect physics theory with neuroscience.

Hundreds of US troops have been sent to the Mexico border amid reported cartel violence, with the United States Coast Guard among the agencies drawing public attention. The deployment signals a reinforced security posture along the frontier as officials respond to rising concerns about cartel activity and cross-border threats.

OpenAI has announced solutions to a number of long-standing mathematics problems, produced by an unreleased frontier model. The output is being released as a batch of 722 manuscripts covering 372 families of related results, a scale that has drawn attention among AI and mathematics researchers who are assessing both the claims and what they suggest about the model's capabilities ahead of any release.

An Oklahoma oil company has plugged a well that was potentially leaking toxic waste, following an investigation by ProPublica and The Frontier. The reporting revealed that state regulators had approved the well in violation of rules designed to protect public drinking water, raising questions about oversight of oil and gas operations and the safety of water supplies in the state.

Reflection AI, a startup founded by two former Google DeepMind researchers, has released a new open-weight AI model that the company says rivals the leading models from the United States and China. The announcement is drawing attention because open-weight releases at frontier-level performance remain rare, with most top models kept closed and proprietary by major AI labs.

Microsoft has published an article outlining three lessons drawn from its frontier AI vulnerability research. The piece distils the company's experience probing advanced AI systems into practical takeaways for security researchers and developers working on emerging models. It lands amid growing attention to AI safety and the security risks posed by increasingly capable systems.

Cosmetics & Toiletries has published a review of advances in scalp health, arguing that treatment strategies should be rethought around a deeper understanding of scalp biology and new technologies. The piece examines how emerging research and formulation tools could shape the future of products targeting the scalp, moving beyond traditional approaches to hair care and dermatological treatment.

Latvian border forces have stopped an attempt by armed migrants to cross the border from Belarus. Officials say the group did not turn back peacefully, and troops were deployed to block the incursion. The incident marks an escalation in tensions along the Latvia–Belarus frontier, which has seen repeated pressure from organised migrant crossings that Latvia, Lithuania and Poland describe as deliberately engineered by Minsk.

Google and Unity have jointly launched a new platform that lets users create video games using text prompts, according to Bloomberg. The tool applies generative AI to game development, lowering the barrier for people without coding or design experience to build playable games. The move highlights the accelerating push by major tech companies to bring generative AI tools into creative industries, with the gaming sector seen as a key frontier.
