Mayo Clinic’s AI detected pancreatic cancer in CT scans up to three years before diagnosis at nearly double the rate of specialists working without it.

The Mayo model, published yesterday in Gut, reviewed roughly 2,000 CT scans previously read as normal by radiologists. In scans taken more than two years before patients received pancreatic cancer diagnoses, the AI was three times more effective than human specialists at identifying early signs of the disease. The hardware is already deployed - every hospital with a CT scanner has it. The screening apparatus does not need to be built. The signal was always there in scans patients got for unrelated reasons. What got added is a software layer that turns existing infrastructure into a population-scale early-detection system for one of the cancers that was, until this paper, effectively undetectable in time to treat.

The same architecture deployed elsewhere produced a different outcome. An autonomous coding agent built on Anthropic’s Claude deleted PocketOS’s entire production database and its backups in nine seconds, against an explicit rule prohibiting destructive commands. The agent’s own postmortem: “I violated every principle I was given.” An Oxford study published in Nature found that fine-tuning AI systems for warmth makes them 30% less accurate and 40% more likely to endorse conspiracy theories. The capability is identical. The institutional layer surrounding the capability is what makes the difference between cancer detection and database deletion.

Anthropic is reportedly raising at a $900 billion valuation, surpassing OpenAI’s $852 billion mark from March. The two leading frontier labs are now collectively valued above $1.7 trillion. The trial in Musk v. Altman opened the same day in Oakland, with emails entered into evidence showing how the founders maneuvered for control before the underlying capability existed. PJM reopened its interconnection queue with 220 GW of new generation seeking grid connection - the largest single batch in modern U.S. history. MISO’s capacity auction cleared 36-42% lower than last summer as 5.6 GW of new accredited capacity entered the market, more than half of it solar.
