"The Associated Press is reporting on a new study in Nature Astronomy suggesting that a tiny, icy world beyond Pluto harbors a thin, delicate atmosphere that may have been created by volcanic eruptions or a comet strike," writes longtime Slashdot reader fahrbot-bot. From the report: Just 300 miles (500 kilometers) or so across, this mini Pluto is thought to be the solar system's smallest object yet with a clearly detected global atmosphere bound by gravity, said lead researcher Ko Arimatsu of the National Astronomical Observatory of Japan. This so-called minor planet -- formally known as (612533) 2002 XV93 -- is considered a plutino, circling the sun twice in the time it takes Neptune to complete three solar orbits. At the time of the study, it was more than 3.4 billion miles (5.5 billion kilometers) away, farther than even Pluto, the only other object in the Kuiper Belt with an observed atmosphere. This cosmic iceball's atmosphere is believed to be 5 million to 10 million times thinner than Earth's protective atmosphere, according to the the study [...]. It's 50 to 100 times thinner than even Pluto's tenuous atmosphere. The likeliest atmospheric chemicals are methane, nitrogen or carbon monoxide, any of which could reproduce the observed dimming as the object passed before the star, according to Arimatsu. Further observations, especially by NASA's Webb Space Telescope, could verify the makeup of the atmosphere, according to Arimatsu.

OpenAI president Greg Brockman's testimony dominated the fifth day of the trial for Elon Musk's lawsuit against the AI company. Brockman took the witness stand on Monday, disclosing that his stake in OpenAI is worth nearly $30 billion, despite not personally investing money in OpenAI. The judge also declined to admit a pretrial text in which Musk allegedly warned Brockman that he and Altman would become "the most hated men in America." From a report: Brockman's disclosure would put him on the Forbes list of the world's richest people, with wealth comparable to Melinda French Gates. [...] Late Sunday, OpenAI lawyers tried to admit as evidence a text message Musk sent to Brockman two days before the trial began. According to a court filing -- which did not include the actual text exchange -- Musk sent a message to Brockman to gauge interest in settlement. When Brockman replied that both sides should drop their respective claims, Musk shot back, according to the filing, "By the end of this week, you and Sam will be the most hated men in America. If you insist, so it will be." Judge Yvonne Gonzalez Rogers, who is overseeing the trial, did not admit the text exchange as evidence. Brockman acknowledged that he had promised to personally donate $100,000 to OpenAI's charity but never did. In explaining the delay, Brockman put the onus on Altman: "I asked Sam when I should donate this, and he said he would let me know," reports Business Insider. The first witness to testify on Monday was Stuart Russell, an artificial intelligence expert who teaches computer science at the University of California, Berkeley. "The most memorable part of Russell's testimony was when he talked about how much Musk's legal team paid him," notes Business Insider. "He received an eye-popping $5,000 per hour for 40 hours of preparatory work. Expert witnesses in high-profile cases typically make between $500 to $1,000 per hour."

The Trump administration is reportedly considering an executive order to create a working group that could review advanced AI models before public release. The shift follows concerns over Anthropic's powerful Mythos model and its cyber capabilities, with officials weighing whether the government should get early access to frontier models without necessarily blocking their release. The New York Times reports: In meetings last week, White House officials told executives from Anthropic, Google and OpenAI about some of those plans, people briefed on the conversations said. The working group is likely to consider a number of oversight approaches, officials said. But a review process could be similar to one being developed in Britain, which has assigned several government bodies to ensure that A.I. models meet certain safety standards, people in the tech industry and the administration said. The discussions signal a stark reversal in the Trump administration's approach to A.I. Since returning to office last year, Mr. Trump has been a major booster of the technology, which he has said is vital to winning the geopolitical contest against China. Among other moves, he swiftly rolled back a Biden administration regulatory process that asked A.I. developers to perform safety evaluations and report on A.I. models with potential military applications. "We're going to make this industry absolutely the top, because right now it's a beautiful baby that's born," Mr. Trump said of A.I. at an event in July. "We have to grow that baby and let that baby thrive. We can't stop it. We can't stop it with politics. We can't stop it with foolish rules and even stupid rules." Mr. Trump left room for some rules, but he added that "they have to be more brilliant than even the technology itself." The White House wants to avoid any political repercussions if a devastating A.I.-enabled cyberattack were to occur, people in the tech industry and the administration said. The administration is also evaluating whether new A.I. models could yield cyber-capabilities that could be useful to the Pentagon and U.S. intelligence agencies, they said. To get ahead of models like Mythos, some officials are pushing for a review system that would give the government first access to A.I. models, but that would not block their release, people briefed on the talks said.
