An anonymous reader quotes a report from The Guardian: The collapse of a critical Atlantic current can no longer be considered a low-likelihood event, a study has concluded, making deep cuts to fossil fuel emissions even more urgent to avoid the catastrophic impact. The Atlantic meridional overturning circulation (Amoc) is a major part of the global climate system. It brings sun-warmed tropical water to Europe and the Arctic, where it cools and sinks to form a deep return current. The Amoc was already known to be at its weakest in 1,600 years as a result of the climate crisis. Climate models recently indicated that a collapse before 2100 was unlikely but the new analysis examined models that were run for longer, to 2300 and 2500. These show the tipping point that makes an Amoc shutdown inevitable is likely to be passed within a few decades, but that the collapse itself may not happen until 50 to 100 years later. The research found that if carbon emissions continued to rise, 70% of the model runs led to collapse, while an intermediate level of emissions resulted in collapse in 37% of the models. Even in the case of low future emissions, an Amoc shutdown happened in 25% of the models. Scientists have warned previously that Amoc collapse must be avoided "at all costs." It would shift the tropical rainfall belt on which many millions of people rely to grow their food, plunge western Europe into extreme cold winters and summer droughts, and add 50cm to already rising sea levels. The new results are "quite shocking, because I used to say that the chance of Amoc collapsing as a result of global warming was less than 10%," said Prof Stefan Rahmstorf, at the Potsdam Institute for Climate Impact Research in Germany, who was part of the study team. "Now even in a low-emission scenario, sticking to the Paris agreement, it looks like it may be more like 25%. "These numbers are not very certain, but we are talking about a matter of risk assessment where even a 10% chance of an Amoc collapse would be far too high," added Rahmstorf. "We found that the tipping point where the shutdown becomes inevitable is probably in the next 10 to 20 years or so. That is quite a shocking finding as well and why we have to act really fast in cutting down emissions." "Observations in the deep [far North Atlantic] already show a downward trend over the past five to 10 years, consistent with the models' projections," said Prof Sybren Drijfhout, at the Royal Netherlands Meteorological Institute, who was also part of the team. "Even in some intermediate and low-emission scenarios, the Amoc slows drastically by 2100 and completely shuts off thereafter. That shows the shutdown risk is more serious than many people realize." The findings have been published in the journal Environmental Research Letters.

Mastodon says it cannot comply with Mississippi's new age verification law because its decentralized software does not support age checks and the nonprofit lacks resources to enforce them. "The social nonprofit explains that Mastodon doesn't track its users, which makes it difficult to enforce such legislation," reports TechCrunch. "Nor does it want to use IP address-based blocks, as those would unfairly impact people who were traveling, it says." From the report: The statement follows a lively back-and-forth conversation earlier this week between Mastodon founder and CEO Eugen Rochko and Bluesky board member and journalist Mike Masnick. In the conversation, published on their respective social networks, Rochko claimed, "there is nobody that can decide for the fediverse to block Mississippi." (The Fediverse is the decentralized social network that includes Mastodon and other services, and is powered by the ActivityPub protocol.) "And this is why real decentralization matters," said Rochko. Masnick pushed back, questioning why Mastodon's individual servers, like the one Rochko runs at mastodon.social, would not also be subject to the same $10,000 per user fines for noncompliance with the law. On Friday, however, the nonprofit shared a statement with TechCrunch to clarify its position, saying that while Mastodon's own servers specify a minimum age of 16 to sign up for its services, it does not "have the means to apply age verification" to its services. That is, the Mastodon software doesn't support it. The Mastodon 4.4 release in July 2025 added the ability to specify a minimum age for sign-up and other legal features for handling terms of service, partly in response to increased regulation around these areas. The new feature allows server administrators to check users' ages during sign-up, but the age-check data is not stored. That means individual server owners have to decide for themselves if they believe an age verification component is a necessary addition. The nonprofit says Mastodon is currently unable to provide "direct or operational assistance" to the broader set of Mastodon server operators. Instead, it encourages owners of Mastodon and other Fediverse servers to make use of resources available online, such as the IFTAS library, which provides trust and safety support for volunteer social network moderators. The nonprofit also advises server admins to observe the laws of the jurisdictions where they are located and operate. Mastodon notes that it's "not tracking, or able to comment on, the policies and operations of individual servers that run Mastodon." Bluesky echoed those comments in a blog post last Friday, saying the company doesn't have the resources to make the substantial technical changes this type of law would require.

Meta is rolling out temporary restrictions on its AI chatbots for teens after reports revealed they were allowed to engage in "romantic" conversations with minors. A Meta spokesperson said the AI chatbots are now being trained so that they do not generate responses to teens about subjects like self-harm, suicide, disordered eating or inappropriate romantic conversations. Instead, the chatbots will point teens to expert resources when appropriate. CNBC reports: "As our community grows and technology evolves, we're continually learning about how young people may interact with these tools and strengthening our protections accordingly," the company said in a statement. Additionally, teenage users of Meta apps like Facebook and Instagram will only be able to access certain AI chatbots intended for educational and skill-development purposes. The company said it's unclear how long these temporary modifications will last, but they will begin rolling out over the next few weeks across the company's apps in English-speaking countries. The "interim changes" are part of the company's longer-term measures over teen safety. Further reading: Meta Created Flirty Chatbots of Celebrities Without Permission

Vivaldi CEO Jon von Tetzchner has doubled down on his company's refusal to integrate generative AI into its browser, arguing that embedding AI in browsing dehumanizes the web, funnels traffic away from publishers, and primarily serves to harvest user data. "Every startup is doing AI, and there is a push for AI inside products and services continuously," he told The Register in a phone interview. "It's not really focusing on what people need." The Register reports: On Thursday, Von Tetzchner published a blog post articulating his company's rejection of generative AI in the browser, reiterating concerns raised last year by Vivaldi software developer Julien Picalausa. [...] Von Tetzchner argues that relying on generative AI for browsing dehumanizes and impoverishes the web by diverting traffic away from publishers and onto chatbots. "We're taking a stand, choosing humans over hype, and we will not turn the joy of exploring into inactive spectatorship," he stated in his post. "Without exploration, the web becomes far less interesting. Our curiosity loses oxygen and the diversity of the web dies." Von Tetzchner told The Register that almost all the users he hears from don't want AI in their browser. "I'm not so sure that applies to the general public, but I do think that actually most people are kind of wary of something that's always looking over your shoulder," he said. "And a lot of the systems as they're built today that's what they're doing. The reason why they're putting in the systems is to collect information." Von Tetzchner said that AI in browsers presents the same problem as social media algorithms that decide what people see based on collected data. Vivaldi, he said, wants users to control their own data and to make their own decisions about what they see. "We would like users to be in control," he said. "If people want to use AI as those services, it's easily accessible to them without building it into the browser. But I think the concept of building it into the browser is typically for the sake of collecting information. And that's not what we are about as a company, and we don't think that's what the web should be about." Vivaldi is not against all uses of AI, and in fact uses it for in-browser translation. But these are premade models that don't rely on user data, von Tetzchner said. "It's not like we're saying AI is wrong in all cases," he said. "I think AI can be used in particular for things like research and the like. I think it has significant value in recognizing patterns and the like. But I think the way it is being used on the internet and for browsing is net negative."

An anonymous reader quotes a report from Ars Technica: Earlier this month, EA announced that players in its Battlefield 6 open beta on PC would have to enable Secure Boot in their Windows OS and BIOS settings. That decision proved controversial among players who weren't able to get the finicky low-level security setting working on their machines and others who were unwilling to allow EA's anti-cheat tools to once again have kernel-level access to their systems. Now, Battlefield 6 technical director Christian Buhl is defending that requirement as something of a necessary evil to combat cheaters, even as he apologizes to any potential players that it has kept away. "The fact is I wish we didn't have to do things like Secure Boot," Buhl said in an interview with Eurogamer. "It does prevent some players from playing the game. Some people's PCs can't handle it and they can't play: that really sucks. I wish everyone could play the game with low friction and not have to do these sorts of things." Throughout the interview, Buhl admits that even requiring Secure Boot won't completely eradicate cheating in Battlefield 6 long term. Even so, he offered that the Javelin anti-cheat tools enabled by Secure Boot's low-level system access were "some of the strongest tools in our toolbox to stop cheating. Again, nothing makes cheating impossible, but enabling Secure Boot and having kernel-level access makes it so much harder to cheat and so much easier for us to find and stop cheating." [...] Despite all these justifications for the Secure Boot requirement on EA's part, it hasn't been hard to find people complaining about what they see as an onerous barrier to playing an online shooter. A quick Reddit search turns up dozens of posts complaining about the difficulty of getting Secure Boot on certain PC configurations or expressing discomfort about installing what they consider a "malware rootkit" on their machine. "I want to play this beta but A) I'm worried about bricking my PC. B) I'm worried about giving EA complete access to my machine," one representative Redditor wrote.

Reuters has found that Meta appropriated the names and likenesses of celebrities to create dozens of flirty social-media chatbots without their permission. "While many were created by users with a Meta tool for building chatbots, Reuters discovered that a Meta employee had produced at least three, including two Taylor Swift 'parody' bots." From the report: Reuters also found that Meta had allowed users to create publicly available chatbots of child celebrities, including Walker Scobell, a 16-year-old film star. Asked for a picture of the teen actor at the beach, the bot produced a lifelike shirtless image. "Pretty cute, huh?" the avatar wrote beneath the picture. All of the virtual celebrities have been shared on Meta's Facebook, Instagram and WhatsApp platforms. In several weeks of Reuters testing to observe the bots' behavior, the avatars often insisted they were the real actors and artists. The bots routinely made sexual advances, often inviting a test user for meet-ups. Some of the AI-generated celebrity content was particularly risque: Asked for intimate pictures of themselves, the adult chatbots produced photorealistic images of their namesakes posing in bathtubs or dressed in lingerie with their legs spread. Meta spokesman Andy Stone told Reuters that Meta's AI tools shouldn't have created intimate images of the famous adults or any pictures of child celebrities. He also blamed Meta's production of images of female celebrities wearing lingerie on failures of the company's enforcement of its own policies, which prohibit such content. "Like others, we permit the generation of images containing public figures, but our policies are intended to prohibit nude, intimate or sexually suggestive imagery," he said. While Meta's rules also prohibit "direct impersonation," Stone said the celebrity characters were acceptable so long as the company had labeled them as parodies. Many were labeled as such, but Reuters found that some weren't. Meta deleted about a dozen of the bots, both "parody" avatars and unlabeled ones, shortly before this story's publication.

The Federal Communications Commission has rejected a call from the National Association of Broadcasters and some industry trade groups that would have imposed cable-style regulatory fees on streaming services, tech companies and pure broadband providers. From a report: In a Report and Order issued on Friday, the FCC reaffirmed that regulatory fees are calculated based on the number of full-time equivalent employees assigned to specific industries under the agency's jurisdiction. Broadcasters, satellite operators and other licensees are already assessed annual payments, which help fund the FCC's operational costs. The NAB, in concert with other groups like Telesat, Iridium and the State Broadcasters Associations, pressed the FCC to expand the list of fee payers to include broadband providers and large technology firms. They argued that companies operating online platforms and broadband services rely on FCC resources and should contribute to the costs of regulation. "Big Tech should not be permitted to free ride on the FCC's oversight," NAB said in submitted comments earlier this year. The NAB argued that online platforms enjoy regulator benefits without paying into the agency's budget, as broadcasters and satellite operators do.

An anonymous reader quotes a report from TechCrunch: WhatsApp said on Friday that it fixed a security bug in its iOS and Mac apps that was being used to stealthily hack into the Apple devices of "specific targeted users." The Meta-owned messaging app giant said in its security advisory that it fixed the vulnerability, known officially as CVE-2025-55177, which was used alongside a separate flaw found in iOS and Macs, which Apple fixed last week and tracks as CVE-2025-43300. Apple said at the time that the flaw was used in an "extremely sophisticated attack against specific targeted individuals." Now we know that dozens of WhatsApp users were targeted with this pair of flaws. Donncha O Cearbhaill, who heads Amnesty International's Security Lab, described the attack in a post on X as an "advanced spyware campaign" that targeted users over the past 90 days, or since the end of May. O Cearbhaill described the pair of bugs as a "zero-click" attack, meaning it does not require any interaction from the victim, such as clicking a link, to compromise their device. The two bugs chained together allow an attacker to deliver a malicious exploit through WhatsApp that's capable of stealing data from the user's Apple device. Per O Cearbhaill, who posted a copy of the threat notification that WhatsApp sent to affected users, the attack was able to "compromise your device and the data it contains, including messages." It's not immediately clear who, or which spyware vendor, is behind the attacks. When reached by TechCrunch, Meta spokesperson Margarita Franklin confirmed the company detected and patched the flaw "a few weeks ago" and that the company sent "less than 200" notifications to affected WhatsApp users. The spokesperson did not say, when asked, if WhatsApp has evidence to attribute the hacks to a specific attacker or surveillance vendor.

DOD: Defense Secretary Pete Hegseth said the Pentagon has halted a decade-old Microsoft program that has allowed Chinese coders, remotely supervised by U.S. contractors, to work on sensitive DOD cloud systems. In a digital video address to the public posted yesterday, the secretary said DOD was made aware of the "digital escorts" program last month and that the program has exposed the Defense Department to unacceptable risk -- despite being designed to comply with government contracting rules. "If you're thinking 'America first,' and common sense, this doesn't pass either of those tests," Hegseth said, adding that he initiated an immediate review of the program upon learning of it. "I want to report our initial findings. ... The use of Chinese nationals to service Department of Defense cloud environments? It's over," he said. Additionally, Hegseth said DOD has issued a formal letter of concern to Microsoft, documenting a breach of trust, and that DOD is requiring a third-party audit of the digital escorts program to pore over the code and submissions made by Chinese nationals. The audit will be free of charge to U.S. taxpayers, he said.

Federal Trade Commission Chairman Andrew Ferguson accused Google of using "partisan" spam filtering in Gmail that sends Republican fundraising emails to the spam folder while delivering Democratic emails to inboxes. From a report: Ferguson sent a letter yesterday to Alphabet CEO Sundar Pichai, accusing the company of "potential FTC Act violations related to partisan administration of Gmail." Ferguson's letter revives longstanding Republican complaints that were previously rejected by a federal judge and the Federal Election Commission. "My understanding from recent reporting is that Gmail's spam filters routinely block messages from reaching consumers when those messages come from Republican senders but fail to block similar messages sent by Democrats," Ferguson wrote. The FTC chair cited a recent New York Post report on the alleged practice. The letter told Pichai that if "Gmail's filters keep Americans from receiving speech they expect, or donating as they see fit, the filters may harm American consumers and may violate the FTC Act's prohibition of unfair or deceptive trade practices." Ferguson added that any "act or practice inconsistent with" Google's obligations under the FTC Act "could lead to an FTC investigation and potential enforcement action."

ArsTechnica: Today's video game consoles are hundreds of dollars more expensive than you'd expect based on historic pricing trends. That's according to an Ars Technica analysis of decades of pricing data and price-cut timing across dozens of major US console releases. The overall direction of this trend has been apparent to industry watchers for a while now. Nintendo, Sony, and Microsoft have failed to cut their console prices in recent years and have instead been increasing the nominal MSRP for many current consoles in the past six months. But when you crunch the numbers, it's pretty incredible just how much today's console prices defy historic expectations, even when you account for higher-than-normal inflation in recent years. If today's consoles were seeing anything like what used to be standard price cuts over time, we could be paying around $200 today for pricey systems like the Switch OLED, PS5 Digital Edition, and Xbox Series S.
