Physicists report creating a record-breaking Schrödinger's cat state, a quantum superposition in which atoms exist in two states at once, using some of the most unusual atoms in physics. The experiment pushes the known limits of how large an object can be while remaining in a quantum superposition, a milestone for quantum physics research.

Ukraine has announced a large-scale programme to build an 'army of robots', described by officials as a 'Manhattan Project for physical AI'. The initiative aims to develop autonomous ground and aerial systems at scale for battlefield use, drawing comparisons to the World War Two atomic research effort. The announcement has drawn international attention given Ukraine's ongoing war with Russia and the growing role of drones and robotics in modern combat.

Bloomberg reports that driverless trucks may provide a model for how autonomous AI systems can be deployed safely without harming people. The argument is that self-driving freight has operated under strict testing, regulation and limited-use conditions, offering a template for governing more advanced robots. The piece adds to ongoing debate about how to manage AI risks as automation expands into physical industries.

Gecko Robotics' chief executive is arguing that humans must remain in control as artificial intelligence moves into the physical world through robots and industrial automation. The company builds robots used to inspect critical infrastructure such as bridges, power plants and pipelines. The intervention adds a robotics industry voice to the ongoing debate over how much autonomy should be granted to AI-driven machines in safety-critical settings.

Niantic Spatial says its spatial AI technology is being applied to real-world robots, extending the company's geospatial mapping work beyond games and consumer apps into robotics. The move signals the firm's push into physical-world AI, where spatial understanding helps machines navigate and interact with their surroundings.

A new benchmark called RoboHarm examines whether frontier AI models used to control robots refuse unsafe instructions. The project, hosted by RoboCurve, raises safety questions about AI-driven robotics as language-model-based policies move into physical systems. Discussion is active among robotics and AI safety communities, with many debating how well current models handle harmful or dangerous commands before deployment.

An AI system has reportedly set a record by independently computing a 9-loop physics amplitude, a Feynman diagram calculation far beyond typical human work. Most real-world perturbative calculations in quantum field theory stop at 2 or 3 loops due to their complexity. The result highlights how machine learning is beginning to automate some of the most demanding mathematical tasks in theoretical physics.

The Albuquerque Journal takes readers inside Sandia National Laboratories' Z machine in New Mexico, the world's most powerful pulsed-power facility. Originally built to study materials under nuclear weapons conditions, the device is now central to research on fusion energy, exploring how the same physics that powers warheads could one day deliver clean, abundant power.

India head coach Gautam Gambhir is making player fitness the central priority in the team's buildup to the 2027 ICC Cricket World Cup. The approach signals that selection and workload management will be tied closely to physical readiness, with the tournament in South Africa, Zimbabwe and Namibia seen as the long-term target for the squad's core players.

Startup Midcentury has raised a $15 million seed round to build training data for physical AI systems such as robots and autonomous machines. The funding signals continued investor appetite for startups supplying high-quality data to the physical AI sector, where collecting real-world sensor and motion data is considered a key bottleneck for training capable models.

A British startup is turning video game controller inputs into training data for AI models designed to navigate the physical world. The idea is that human gameplay, including mistakes and clumsy manoeuvring, offers rich examples of how people learn to control complex systems, which could help robots and other embodied AI improve. The approach is drawing attention as a cheaper alternative to real-world data collection.

Cash hoarding is on the rise in the UK, and commentators argue it shows people still want money they can hold and use without asking permission from banks or authorities. The claim ties the surge in physical banknote holding to broader scepticism about financial institutions and renewed interest in alternative, permissionless forms of money.
