Protesters clashed with police forces during a demonstration against the upcoming G7 summit in Geneva. Tear gas and a water cannon were deployed to disperse the large crowd after protesters smashed windows and set a car on fire. What needs to be understood is the message, the basic message regarding all these countries that oppress us through money and power, said one protester who was disappointed to see the protest turn violent. The G7 summit starts on 15 June in Évian-les-Bains and will bring together the leaders of Britain, France, Canada, Germany, Italy, Japan, the United States and the European Union. Pope Leo XIV says Barcelona's iconic Sagrada Família is a masterpiece of stones, colours and light during his visit to Spain.

Pope Leo XIV has described Barcelona's Sagrada Família as a masterpiece of stones, colours and light as he inaugurated its newest - and tallest - tower. The giant Tower of Jesus Christ, completed in February, has brought the church to a soaring height of 172.5m (566ft) - cementing it as the tallest church in the world. His visit to the iconic basilica also marks 100 years since the death of its architect, Antoni Gaudí. Among those attending the service were Spanish royals King Felipe VI and Queen Letizia, as well as Prime Minister Pedro Sánchez. The pope's week-long visit to Spain, which began on Saturday, is the first by a pope in some 15 years.

Claire chatted to Maria Guix from the University of Barcelona about combining electronics and biology to create biohybrid robots with emergent properties. Maria Guix is a chemist and nanotechnology researcher in the University of Barcelona's ChemInFlow lab, developing miniaturised living robots and integrating flexible sensors into microfluidic platforms to better understand biohybrid robotic platforms. She has held postdoctoral positions at IFW Dresden, Purdue University, and the Institute for Bioengineering of Catalonia, advancing biocompatible micromotors, magnetic microrobot automation, and functional living robots.

Researchers now think at least two more groups joined the macabre custom. Breakthroughs, discoveries, and DIY tips sent six days a week. Archaeologists have spent years puzzling over evidence of severed head rituals among Iron Age communities in the northeast Iberian Peninsula. Multiple groups of the Indigetes and Laietani peoples from present-day Spain and Portugal practiced these violent public displays at least as far back as the first millennium BCE. And sometimes, they did so with elaborate preparation techniques such as driving iron nails through the skulls .

Ensuring reliability in modern software systems requires rigorous pre-production testing across highly heterogeneous and evolving environments. Because exhaustive evaluation is infeasible, practitioners must decide how to allocate limited testing resources across configurations where failure probabilities may drift over time. Existing combinatorial optimization approaches are static, ad hoc, and poorly suited to such non-stationary settings. We introduce a novel reinforcement learning (RL) framework that recasts configuration allocation as a sequential decision-making problem. Our method is the first to integrate Q-learning with a hybrid reward design that fuses simulated outcomes and real-time feedback, enabling both sample efficiency and robustness. In addition, we develop an adaptive online-offline training scheme that allows the agent to quickly track abrupt probability shifts while maintaining long-run stability. Extensive simulation studies demonstrate that our approach consistently outperforms static and optimization-based baselines, approaching oracle performance. This work establishes RL as a powerful new paradigm for adaptive configuration allocation, advancing beyond traditional methods and offering broad applicability to dynamic testing and resource scheduling domains.
