In Reddit's "Family Medicine" subreddit, a moderator noticed earlier this week that the AI-powered "Reddit Answers" was automatically responding to posters, typically with "something related to what was posted." Unfortunately, that moderator says, Reddit Answers "has been spreading grossly dangerous misinformation."And yet Reddit's moderators "cannot disable this feature." Elsewhere a healthcare worker described what happened when they tested Reddit Answers: I made a post in r/familymedicine and a link appeared below it with information on treating chronic pain. The first post it cited urged people to stop their prescribed medications and take high-dose kratom which is an illegal (in some states) and unregulated substance. I absolutely do not endorse this... I also asked about the medical indications for heroin. One answer warned about addiction and linked to crisis and recovery resources. The other connects to a post where someone claims heroin saved their life and controls their chronic pain. The post was encouraging people to stop prescribed medications and use heroin instead. Heroin is a schedule I drug in the US which means there are no acceptable uses. It's incredibly addictive and dangerous. It is responsible for the loss of so many lives... The AI-generated answers could easily be mistaken as information endorsed by the sub it appears in. r/familymedicine absolutely does not endorse using heroin to treat chronic pain. This feature needs to be disabled in medical and mental health subs, or allow moderators of these subreddits to opt out. Better filters are also needed when users ask Reddit Answers health related questions. If this continues there will be adverse outcomes. People will be harmed. This needs to change. Two days ago an official Reddit "Admin" posted that "We've made some changes to where Answers appears based on this feedback," adding that beyond that Reddit "will continue to tweak based on what we're seeing and hearing." But the "Family Medicine" subreddit still has a top-of-page announcement warning every user there... "We do NOT and CANNOT endorse Reddit Answers at this time and urge every user of this sub to disregard anything it says."

Cybercriminals are exploiting weak email authentication settings in Zendesk, using the platform's customer support systems to bombard targets with thousands of spam and harassing messages that appear to come from legitimate companies like The Washington Post, Discord, and NordVPN. KrebsOnSecurity reports: Zendesk is an automated help desk service designed to make it simple for people to contact companies for customer support issues. Earlier this week, KrebsOnSecurity started receiving thousands of ticket creation notification messages through Zendesk in rapid succession, each bearing the name of different Zendesk customers, such as CapCom, CompTIA, Discord, GMAC, NordVPN, The Washington Post, and Tinder. The abusive missives sent via Zendesk's platform can include any subject line chosen by the abusers. In my case, the messages variously warned about a supposed law enforcement investigation involving KrebsOnSecurity.com, or else contained personal insults. Moreover, the automated messages that are sent out from this type of abuse all come from customer domain names -- not from Zendesk. [...] In all of the cases above, the messaging abuse would not have been possible if Zendesk customers validated support request email addresses prior to sending responses. Failing to do so may make it easier for Zendesk clients to handle customer support requests, but it also allows ne'er-do-wells to sully the sender's brand in service of disruptive and malicious email floods. "We recognize that our systems were leveraged against you in a distributed, many-against-one manner," said Carolyn Camoens, communications director at Zendesk. "We are actively investigating additional preventive measures. We are also advising customers experiencing this type of activity to follow our general security best practices and configure an authenticated ticket creation workflow."

Taps Ruby core to oversee RubyGems, Bundler

Ruby Central, the non-profit that recently seized some Ruby open source tools from maintainers, is transferring the repository ownership of RubyGems and Bundler to the Ruby core team. The move appears to be an attempt to mollify the Ruby community following a divisive power grab, but it does not restore the control of those tools to the maintainers who previously oversaw them.…

In two separate reports, Apple and Samsung are said to report underwhelming sales of their new ultra-thin smartphones. According to The Elec, Apple plans to cut production of the iPhone Air while Samsung has canceled its planned Galaxy S26 Edge smartphone after disappointing sales of the Galaxy S25 Edge, Korea's NewsPim claims. MacRumors reports: Samsung apparently halted work on the Galaxy S26 Edge this week, informing employees internally that the product line would be discontinued. Internal discussions in September shifted priorities toward the more conventional "Plus" form factor after confirming that consumer demand for ultra-slim flagships was weaker than expected. [...] Samsung will apparently instead add a Galaxy S26 Plus model to its 2026 lineup, reverting to the company's traditional three-tier structure of base, Plus, and Ultra variants. Despite the cancellation, development of the Galaxy S26 Edge was already complete. Development of the S26 Plus is expected to begin before the end of the third quarter of 2025. The atmosphere inside the company is said to be "chaotic" and "embarrassed" following the sudden lineup revision. Samsung reportedly plans to sell through existing inventory of the Galaxy S25 Edge and cease further production once stock is depleted. As for Apple's iPhone Air, here's what MacRumors is reporting: The Japanese investment banking and securities firm claims that the iPhone 17 Pro and iPhone 17 Pro Max are seeing higher sales than their predecessors during the same period last year, while the standard iPhone 17 is a major success, performing significantly better than the iPhone 16. The iPhone Air is apparently the outlier; Apple plans to reduce production by one million units this year. Meanwhile, Apple plans to increase production of all other models by two million units. The overall production forecast of the iPhone 17 series this year has also been increased from 88 million units to 94 million units for the start of 2026.

A network of classified Starshield satellites built by SpaceX for the U.S. government is transmitting signals on radio frequencies reserved for Earth-to-space commands. According to NPR, it may violate international standards. From the report: Satellites associated with the Starshield satellite network appear to be transmitting to the Earth's surface on frequencies normally used for doing the exact opposite: sending commands from Earth to satellites in space. The use of those frequencies to "downlink" data runs counter to standards set by the International Telecommunication Union, a United Nations agency that seeks to coordinate the use of radio spectrum globally. Starshield's unusual transmissions have the potential to interfere with other scientific and commercial satellites, warns Scott Tilley, an amateur satellite tracker in Canada who first spotted the signals. "Nearby satellites could receive radio-frequency interference and could perhaps not respond properly to commands -- or ignore commands -- from Earth," he told NPR. Outside experts agree there's the potential for radio interference. "I think it is definitely happening," said Kevin Gifford, a computer science professor at the University of Colorado, Boulder who specializes in radio interference from spacecraft. But he said the issue of whether the interference is truly disruptive remains unresolved. [...] Tilley says he's detected signals from 170 of the Starshield satellites so far. All appear in the 2025-2110 MHz range, though the precise frequencies of the signals move around.

An anonymous reader quotes a report from The Conversation: When teachers rely on commonly used artificial intelligence chatbots to devise lesson plans, it does not result in more engaging, immersive or effective learning experiences compared with existing techniques, we found in our recent study. The AI-generated civics lesson plans we analyzed also left out opportunities for students to explore the stories and experiences of traditionally marginalized people. The allure of generative AI as a teaching aid has caught the attention of educators. A Gallup survey from September 2025 found that 60% of K-12 teachers are already using AI in their work, with the most common reported use being teaching preparation and lesson planning. [...] For our research, we began collecting and analyzing AI-generated lesson plans to get a sense of what kinds of instructional plans and materials these tools provide to teachers. We decided to focus on AI-generated lesson plans for civics education because it is essential for students to learn productive ways to participate in the U.S. political system and engage with their communities. To collect data for this study, in August 2024 we prompted three GenAI chatbots -- the GPT-4o model of ChatGPT, Google's Gemini 1.5 Flash model and Microsoft's latest Copilot model -- to generate two sets of lesson plans for eighth grade civics classes based on Massachusetts state standards. One was a standard lesson plan and the other a highly interactive lesson plan. We garnered a dataset of 311 AI-generated lesson plans, featuring a total of 2,230 activities for civic education. We analyzed the dataset using two frameworks designed to assess educational material: Bloom's taxonomy and Banks' four levels of integration of multicultural content. Bloom's taxonomy is a widely used educational framework that distinguishes between "lower-order" thinking skills, including remembering, understanding and applying, and "higher-order" thinking skills -- analyzing, evaluating and creating. Using this framework to analyze the data, we found 90% of the activities promoted only a basic level of thinking for students. Students were encouraged to learn civics through memorizing, reciting, summarizing and applying information, rather than through analyzing and evaluating information, investigating civic issues or engaging in civic action projects. When examining the lesson plans using Banks' four levels of integration of multicultural content model (PDF), which was developed in the 1990s, we found that the AI-generated civics lessons featured a rather narrow view of history -- often leaving out the experiences of women, Black Americans, Latinos and Latinas, Asian and Pacific Islanders, disabled individuals and other groups that have long been overlooked. Only 6% of the lessons included multicultural content. These lessons also tended to focus on heroes and holidays rather than deeper explorations of understanding civics through multiple perspectives. Overall, we found the AI-generated lesson plans to be decidedly boring, traditional and uninspiring. If civics teachers used these AI-generated lesson plans as is, students would miss out on active, engaged learning opportunities to build their understanding of democracy and what it means to be a citizen.

A potential tragedy was narrowly averted at a Wikipedia conference in Manhattan when two volunteer editors tackled an armed man who stormed the stage and threatened to kill himself during a keynote speech (source paywalled; alternative source). The gunman, who claimed he was protesting Wikipedia's policy banning self-identified pedophiles, was disarmed and taken into custody after community members swiftly intervened. The New York Times reports: The armed man came striding up the aisle at a conference for Wikipedia editors Friday morning in Manhattan, several witnesses said. The man, draped in a multicolored flag, walked onto the stage and stood next to Maryana Iskander, the chief of the nonprofit group that runs Wikipedia, interrupting her speech. He announced that he was going to kill himself. He held a gun near his head and pointed it toward the ceiling. The audience of well over a hundred people panicked. "People started yelling, 'Get down, get down!' and people started ducking behind their chairs," said Bill Adair, a journalism professor who was there and is writing a book on Wikipedia. A man in an orange sweatshirt rushed the stage. He was not in law enforcement, but a Wikipedia contributor on the conference's "trust and safety team": Richard Knipel, the City University of New York's "Wikimedian-in-residence." He grabbed the gunman from behind. Another Wikipedian on the trust and safety team, Andrew Lih, had been standing watch in the aisle and charged forward, too. "I saw the gun he's holding go from pointing up at the ceiling to sweeping down toward the room, and as it swept across me I said 'Oh, my god,' and I ducked down, but I still kept moving" said Mr. Lih, a digital strategist who works with museums and libraries. "I grabbed his arm," he continued. "He was still clutching his gun pretty hard. I pried his fingers away from it, removed it from his hands and put it down." The gun was loaded, according to a senior law enforcement official who spoke on the condition of anonymity to discuss a pending investigation. In seconds, a potential scene of bloodshed had been averted, a life may have been saved, and two volunteer editors of an online encyclopedia had become unlikely heroes.

Amazon is investing hundreds of millions into the Cascade Advanced Energy Facility, a next-generation small modular reactor project in Richland, Washington, developed with X-energy and Energy Northwest. "The question now is will it be enough to kick off a new wave of U.S. nuclear energy innovation -- a field that America largely soured on by the 1980s?" writes GeekWire. From the report: The facility will be located near Richland, Wash., near Energy Northwest's Columbia Generating Station nuclear plant. The initial goal is to install a cluster of four small modular reactors (SMRs) that can produce up to 320 megawatts of power, but the overall vision is to construct 12 reactors total, with a capacity of nearly one gigawatt. If all the funding, permitting and public support come together, construction should start within the next five years, with the plant coming online in the 2030s. [...] For Amazon, its support of the Cascade Advanced Energy Facility is part of a much bigger initiative. The company has set a goal of deploying 5 gigawatts of nuclear power in the U.S. by 2039. "One thing that Amazon does well is scale technology," said Brandon Oyer, Amazon Web Services' head of power and water for North and South America. "We've done this over and over again ... We'll go and make an investment and then learn how to scale that up, drive out cost, make it more readily available." Targeting SMRs for amplification was a "natural fit," Oyer added. The company believes nuclear aligns with its climate ambitions. Amazon matches all of its electricity use with clean power and is the largest corporate purchaser of wind, solar and other renewable sources. That said, it is struggling to cut its carbon footprint to reach a goal of net-zero emissions by 2040 as the AI-boom stokes energy use. Amazon reported that its carbon footprint grew by 6% last year. Amazon has dibs on half of the 320 megawatts of electricity that will be generated by the first four reactors at the Washington site, but will take all of it if the power prices are too high for local utilities to afford. Cullen said that if everything goes well with the initial phase, it would be straightforward to build the other eight reactors as the permits will encompass the complete build out. The added reactors would produce enough electricity for about one million homes and should come at a lower cost. "Amazon recognizes the role they can -- and are willing -- to play," Cullen said. The company can take some of the early risk and bring that catalytic capital, he said, which is "every, very difficult for utilities to do."
