An autonomous closed-loop AI system published in Nature discovered a novel passivation molecule and fabricated perovskite solar cells at 27.22% efficiency with five times the reproducibility of manual fabrication - no human hands involved - as JPMorgan’s Jamie Dimon confirmed the bank is testing Claude Mythos and Anthropic publicly opposed an AI liability shield bill that OpenAI backed.

The Nature paper represents a qualitative shift in what autonomous scientific systems can achieve. The framework used active learning and quantum modeling to identify a molecule no human researcher had found, fed the candidate into a robotic fabrication line that used Bayesian optimization in a continuous feedback loop, built solar cells, tested them, and iterated - all without human intervention. The devices retained 98.7% of their initial efficiency after 1,200 hours of continuous operation. The reproducibility finding may carry more structural weight than the efficiency number: perovskite solar cells have been confined to laboratories in part because human variability in fabrication made reliable production at scale extraordinarily difficult. The system solved that by removing the human from the fabrication loop entirely.
Jamie Dimon’s disclosure that JPMorgan Chase is testing Claude Mythos marks the third named major bank confirmation in a week, following Goldman Sachs on Monday. Dimon stated that AI “does create additional vulnerabilities” across exchanges, routers, and interconnected systems, describing a structural reality that extends beyond any single institution. The UK AI Security Institute simultaneously published its independent evaluation confirming Mythos is the first AI system to complete a 32-step autonomous cyberattack simulation, succeeding in three of ten attempts at tasks that would take trained human professionals roughly 20 hours.
Anthropic publicly opposed Illinois SB 3444, the bill OpenAI helped draft, which would eliminate liability for AI labs even in mass-casualty scenarios provided they publish a safety framework on their website. Anthropic called it “a get-out-of-jail-free card against all liability.” The Illinois governor’s office responded that companies should never receive “a full shield that evades responsibilities they should have to protect the public interest.” The two leading frontier AI companies are now actively working the same state legislatures in opposite directions on who bears responsibility when frontier capability causes harm at scale.
A Guardian investigation documented workers describing AI-generated output as “workslop” that increases rather than reduces workload, with 40% of non-managers reporting AI saves them no time. A Stanford-affiliated study estimated $8.1 million in lost productivity for a 10,000-person organization from correction labor alone. The gap between what autonomous systems achieve in purpose-built scientific environments and what they produce when bolted onto existing workflows is where the transition’s growing pains are most visible. Meanwhile, Stegra secured €1.4 billion to complete the world’s first major green-steel mill in Sweden, cutting steelmaking emissions by up to 95% using green hydrogen.
