Good caregivers are often in short supply, but after the Covid-19 pandemic hit the U.S. in early 2020, staff levels at nursing homes dropped by 10 percent. What was a simple personnel shortage has moved closer to being a nursing-care crisis. As it happens, about one-fifth of health care support workers in the U.S. are immigrants. And as a newly published study of the nation's metro areas shows, changes in immigration levels can affect how much nursing care the elderly receive. Overall, Gruber and his colleagues determined that when there is more immigration, registered nurses and other aides work more hours at nursing homes, without displacing already-employed caregivers, while patient outcomes improve. Essentially, a 10 percent increase in female immigrants in a given metro area leads to a 1.1 percent increase in hours that registered nurses spend with elderly patients, while hospitalizations for those patients drop, among other things. 'Even if immigration actually increases labor supply to the medical sector, it was an open question if that would improve outcomes, and it does,' adds Gruber, the Ford Professor of Economics and head of the MIT Department of Economics....
President Trump, celebrating Tehran's declaration that the Strait of Hormuz would reopen to commercial shipping, posted on Truth Social on April 17, 'IRAN HAS JUST ANNOUNCED THAT THE STRAIT OF IRAN IS FULLY OPEN AND READY FOR FULL PASSAGE.' The opening didn't last. But, in his haste, Trump had inadvertently spelled out possibly the most consequential result of his eight-week war: The Strait of Hormuz now looks, in practice, like the 'STRAIT OF IRAN.' Although none of the Trump administration's goals'an end to Iran's nuclear ambitions, destroying Iran's missile capability, neutralizing proxy forces, regime change'has been fulfilled, the war has led to enduring changes. Two sweeping conclusions'one short-term, one longer'have become clear, experts in defense, diplomacy, business, and economics told us. In the short term, despite an indefinite cease-fire that kicked in last week following an initial two-week pause in hostilities, a durable end to the war isn't coming anytime soon. The disparity in U.S. and Iranian demands for how negotiations should proceed, along with blockades by their respective forces in the strait, has locked the two sides in a stalemate. Many Americans still expect a quick end to the war's economic strain. But that's unlikely. At a Vanderbilt University panel discussion on warfare this week, the moderator asked when the effects of the war might end. A retired general, a retired CIA analyst, and an energy-industry executive said anywhere from two to nine months, prompting a collective intake of breath from the audience....
The most interesting thing about DeepSeek-V4 is not that it supports a one-million-token context window. That number is impressive, but context length by itself is a poor proxy for intelligence. A model can accept a million tokens and still fail to use them. It can drown in KV cache, retrieve the wrong evidence, lose track of local syntax, hallucinate over compressed memory, or turn the entire prompt into a blurry statistical soup. DeepSeek-V4 is best understood as an answer to that question. It is not simply another frontier model release. It is a systems paper about making long-context reasoning practical. The model is designed around a simple but profound premise: million-token intelligence requires more than scaling the Transformer. It requires a new memory hierarchy, new attention mechanics, new training stabilizers, new optimizer choices, new quantization regimes, and a serving stack that can actually survive the economics of inference....
' Hey, Linas here! Every day, I break down 3 stories shaping the future of FinTech & Artificial Intelligence - plus the money movements and trends worth tracking. First time here' 370k+ FinTech and AI leaders get this daily. Join them: Leopold Aschenbrenner is either the most important investor no one on Wall Street has heard of, or the most dangerous kind of genius: one who might actually be right. In the twelve months following the launch of his hedge fund, Situational Awareness LP, in September 2024, he grew its disclosed U.S. equity exposure from roughly $225 million to $5.52 billion ' He did it without owning a single share of Nvidia, Microsoft, Amazon, Google, or Meta. His largest position was in a fuel-cell company. His second-largest was call options on a GPU cloud startup most investors had never heard of. His third-largest was call options on a chipmaker Wall Street had largely written off. This is not a story about luck. It is a story about what happens when a mind trained in growth economics, existential risk theory, and AI scaling laws is given access to public markets and the conviction to act on conclusions everyone else considers too extreme to take seriously....
