From taxable years beginning after 31 December 2026, a saver whose Social Security wages from the plan's own sponsor topped $145,000 the year before can no longer make a pre-tax catch-up contribution. It has to be Roth. The threshold is measured per employer, on last year's wages, which catches people who do not think of themselves as high earners.
A declaration signed by more than 200 figures, including ten Nobel laureates, asked governments to agree international red lines for artificial intelligence by the end of 2026. The year has fifteen weeks left, no binding instrument exists, and the United States rejected the premise outright.
Three rival chief executives spent the weekend agreeing that AI development should slow down. On Sunday in Ireland the president dismissed the idea, saying there are "a lot of negative forces" behind it and that "whoever wins AI wins."

Dario Amodei published an essay on Saturday arguing that frontier AI companies must deliberately slow the rate at which their models improve.

The Justice Department has issued Nvidia a formal demand for information over its licensing arrangement with Groq, in which Groq's chief executive and chief operating officer moved across. The question is whether a licence plus a mass talent transfer is an acquisition that should have been reported. It is the first formal test of a structure the whole industry has been using.
A regulator decides a vaccine is safe and effective. A separate body decides who should prioritise getting it.

From this week, 95 percent of the National Wildlife Refuge System — about 92 million acres — is open to hunting or fishing, through 1,488 new opportunities across 32 states and more than a thousand changes to federal regulations. Fish and Wildlife Service staffing fell 18 percent between April 2024 and May 2025.
A would-be maker of a scarce cancer drug may produce it only while the drug is officially in shortage. Succeed at ending the shortage and the permission ends with it, which is a rule that guarantees nobody builds durable capacity.
In the absence of comprehensive federal legislation, statehouses have produced a growing body of AI law, and companies are complying with the strictest version everywhere.
