The Wall Street Journal reports that Jassy told Treasury Secretary Scott Bessent and other government officials that Amazon researchers used Anthropic's Claude Fable 5 to obtain information that could be used in cyberattacks. The government subsequently imposed an export control ban on the Fable 5 and Mythos 5 models. An Amazon spokesperson said in a statement that while it's 'not uncommon for governments to seek our counsel on potential security risks,' the company does not 'share the details of those discussions.' David Sacks, Trump's former AI czar who now co-chairs the President's Council of Advisors on Science and Technology, offered his own account of the discussions, claiming that 'a highly credible trusted partner of both Anthropic and the USG ['] came forward with a jailbreak.'

The U.S. government on Friday ordered Anthropic to immediately shut off access to two of its most powerful AI models ' Claude Fable 5 and Claude Mythos 5 ' citing national security concerns. Anthropic announced on X that it has complied, but it made clear it thinks the government got this one wrong. The directive, which Anthropic said it received on Friday at 5:21 pm ET, forces the company to disable both models for all users worldwide ' not just the foreign nationals the government's export control order was nominally aimed at. Access to Anthropic's other models isn't affected. Why does any of this matter' Mythos is Anthropic's most capable AI model, one the company previewed in early April and has kept tightly restricted ever since because of what Anthropic described as its exceptional ability to find security vulnerabilities in software. According to Anthropic, Mythos identified flaws in every major operating system and web browser it tested, so rather than release it broadly, the company launched a controlled program called Project Glasswing, sharing it with roughly 50 vetted organizations, including Amazon, Apple, Google, Microsoft, and CrowdStrike, to use for defensive cybersecurity work....

Data centers are allegedly an unmitigated disaster: They guzzle water, strain electric grids, and raise prices, all while offering almost nothing in return. Little wonder that according to a recent Gallup poll, 71 percent of Americans oppose the construction of new AI data centers in their area. Politicians of both parties are proposing moratoriums on new builds, and local officials who have approved construction in the past are losing reelection because of it. Florida Governor Ron DeSantis recently captured a popular feeling about the pointlessness of building new data centers for the purpose of powering AI: 'Oh, we've got to build a data center and charge you more because we want to do videos where I can put your head on Marlon Brando's body and you can be Don Corleone.' But the data-center panic is overblown. Most of the complaints inflate the costs of data centers and overlook the fact that, in some contexts at least, they can bring real benefits. If saying no is good politics, it isn't always good policy....

Debates about vaccines are a recurring feature of contemporary politics. It turns out they actually date back more than 200 years, since the development of the first smallpox vaccine. MIT Professor Thomas Levenson, one of the country's leading science writers, explores this important history in a new book about the contours of anti-vaccination thought. Levenson identifies different types of arguments vaccination opponents have developed through history, to help shed light on our current debates. He spoke with MIT News about his new book, 'A Pox on Fools: The True Believers, Grifters, and Cynics Who Convinced Us to Reject Vaccines,' published this week by Penguin Random House. A: Hesitation, skepticism, and outright opposition to vaccines is not a new thing. It didn't just happen starting in the late 1990s. Opposition to vaccines dates back to the beginning of the vaccine era, around the early 19th century. The first kind of opposition to vaccines is this sense that it violates the moral or the natural order. If you believed that God has authority over all of us and is mindful of everything, intervening in the disease process could seem blasphemous....
