This roundup spans supply chain stress, decarbonization experiments, and the evolving frontier of AI tooling. The naftha shock keeps showing up in unexpected places — now reaching the agricultural sector — while Japan’s industrial players test creative pathways to cut emissions. On the AI side, Anthropic’s recursive self-improvement paper is getting serious attention, and Cognition is folding its Windsurf product into a broader desktop agent hub. Worth watching how international coordination on AI safety develops from here.
