Utah residents and a progressive nonprofit are suing officials over Kevin O'Leary's planned Stratos Project AI data center, arguing that the special authority overseeing it gives unelected officials too much control over land use, taxation, public health, and local governance. The lawsuit comes as O'Leary has agreed to shrink the proposed 40,000-acre project by 75% amid mounting political and community pushback. NBC News reports: The lawsuit was filed Wednesday in Utah's 3rd District Court by the Alliance for a Better Utah and the group of anonymous residents. The plaintiffs hope to challenge the constitutionality of the Military Installation Development Authority (MIDA) -- a special entity that oversees the data center's proposal -- and its approval of the project, a spokesperson for the nonprofit said. Attorney David Irvine, who is representing the plaintiffs, alleges that MIDA is exercising powers as an unelected body that "the Utah Constitution never authorized." "Under the Stratos plan, it would hold permanent, irrevocable control over public health, safety, taxation, and land use across tens of thousands of acres of Box Elder County, with no voter recourse," he said in a statement. The lawsuit alleges that allowing MIDA to oversee the data center's development "irrevocably" cuts off Box Elder County citizens' rights by not allowing sufficient public input in the project. "The Stratos Project Area Plan, and actions taken by MIDA and the Commission to enact the same, puts lawmaking power respecting questions of public health, safety, welfare, morals, taxation, zoning, land use, and the like, in relation to a significant swath of county territory in a non-elected MIDA Board," the complaint reads. In addition to MIDA and the Box Elder County Commission, the lawsuit names Utah Senate President J. Stuart Adams and state Sen. Jerry Stevenson, who also serve as MIDA board members. Irvine said Adams and Stevenson's presence on the MIDA board as active legislators "appears to violate the prohibition on holding more than one office of public trust simultaneously," and claimed this should render the data center's approval "null and void."

After 50 years of searching, astronomers say they have finally found evidence of a long-sought "wind" blowing from Sagittarius A*, the supermassive black hole at the center of the Milky Way. "Unless a black hole exists in a perfect vacuum, it must blow a wind somehow. And there is no perfect vacuum in the universe," team co-leader and Northwestern University researcher Mark Gorski said in a statement. "With new observations, this is the first time we've had a clean enough view to see the wind's imprint. We looked at the data and said, 'There it is. There is the thing that everybody's been looking for for 50 years.'" Space.com reports: Scientists have been aware for some time that feeding black holes launch powerful outflows of material around them, including jets and winds. Winds are caused when matter falling to the black hole is accelerated to near light-speed, generating pressure that pushes infalling material away. That has been seen with ravenously feeding black holes before, but not the barely feeding Sgr A*. Its sparse consumption of material and the fact it is obscured by the plane of the Milky Way from our vantage point have made tracing this wind difficult. Gorski's Northwestern colleague and team co-leader Lena Murchikova pointed out that the scientists were the first to detect molecular gas very close to Sgr A* feeding the supermassive black hole. That makes Sgr A* reassuringly like other supermassive black holes. "The wind is not powerful, and its direction probably wanders with time. It shows that our black hole is not unique, and our place in the universe is not unique," Murchikova added. "To observe our own black hole, we have to look through the plane of our galaxy. That means we have to peer through gas, dust and ionized structures, and you can't really see through all of that easily." While the team's results confirm that Sgr A* is extremely quiet compared to the supermassive black holes that sit in bright, turbulent regions of other galaxies called active galactic nuclei (AGN), this black hole wind is no slouch. In fact, the scientists think that it has been raging for around 20,000 years. "The majority of other galaxies spend most of their lives in a state where they are not particularly active," Murchikova said. "But we can only see them when they are in a fireworks stage. It is very attractive to study black holes when they are in the fireworks stage, but that's not actually their dominant state. "Sgr A* finally gives us a window into the life of a black hole in this quiet state." The team's research was published in The Astrophysical Journal Letters.

An anonymous reader quotes a report from Ars Technica: Just over a year ago, the Trump Administration issued an executive order meant to accelerate the development of nuclear power in the US. While an entire startup ecosystem has developed around the use of different -- and typically smaller -- reactor designs, only one of them has been fully licensed so far, and there are no plans to actually build any instances of that design. The executive order directed the Department of Energy to have three different reactor designs reach criticality in a bit over a year. On Thursday, a startup called Antares announced that a test reactor it had placed at the Idaho National Laboratory had reached criticality, making it the first new design to cross this threshold. Criticality means that the nuclear reactions inside the hardware had become self sustaining; it does not mean the reactor had started to generate power. [...] At the moment, Antares is just testing what it calls a Mark 0 reactor, which is not connected to the power-generation portion. Instead, it's being used to validate the company's modeling of the physical conditions in its reactors and generate safety data that can be used during licensing applications. Attempts to run the entire system, including electrical generation, are expected to happen next year. While the work was done at a Department of Energy Lab, the company is working with the Department of Defense's Project Pele program for developing a mobile nuclear reactor. The company has also received support from NASA.
