Wednesday's IMPULSE: ProPublica names the algorithm — EviCore's "dial" — that turns prior-authorization scores into denials for one in three insured Americans, and walks through the death of a 61-year-old welder twice refused a heart catheterization. Anthropic's Mythos is now inside the largest US banks; tens of thousands of vulnerabilities have surfaced and Treasury and the Fed are calling CEOs about it. The White House quietly drops the FDA-style approval frame for frontier AI. Trump's China delegation leaves Jensen Huang at home. Anthropic launches Claude For Legal with practice-area plugins and connectors to nine legal platforms, then drops itself directly inside Microsoft 365. A Princeton-led Nature paper traces state-coordinated media through training data into model answers about Xi Jinping. And a new London-and-SF lab called Recursive raises money from Nvidia and AMD to automate AI research itself.
