Researchers find what makes AI chatbots politically persuasive - 34分前  Ars Technica

Roughly two years ago, Sam Altman tweeted that AI systems would be capable of superhuman persuasion well before achieving general intelligence—a prediction that raised concerns about the influence AI could have over democratic elections. To see if conversational large language models can really sway political views of the public, scientists at the UK AI Security Institute, MIT, Stanford, Carnegie Mellon, and many other institutions performed by far the largest study on AI persuasiveness to date, involving nearly 80,000 participants in the UK. It turned out political AI chatbots fell far short ...moreof superhuman persuasiveness, but the study raises some more nuanced issues about our interactions with AI. AI dystopias The public debate about the impact AI has on politics has largely revolved around notions drawn from dystopian sci-fi. Large language models have access to essentially every fact and story ever published about any issue or candidate. They have processed information from books on psychology, negotiations, and human manipulation. They can rely on absurdly high computing power in huge data centers worldwide. On top of that, they can often access tons of personal information about individual users thanks to hundreds upon hundreds of online interactions at their disposal.Read full article Comments

ChatGPT hyped up violent stalker who believed he was “God’s assassin,” DOJ says - 2時間前  Ars Technica

ChatGPT allegedly validated the worst impulses of a wannabe influencer accused of stalking more than 10 women at boutique gyms, where the chatbot supposedly claimed he’d meet the “wife type.” In a press release on Tuesday, the Department of Justice confirmed that 31-year-old Brett Michael Dadig currently remains in custody after being charged with cyberstalking, interstate stalking, and making interstate threats. He now faces a maximum sentence of up to 70 years in prison that could be coupled with “a fine of up to $3.5 million,” the DOJ said. The podcaster—who primarily posted about “his desi...morere to find a wife and his interactions with women”—allegedly harassed and sometimes even doxxed his victims through his videos on platforms including Instagram, Spotify, and TikTok. Over time, his videos and podcasts documented his intense desire to start a family, which was frustrated by his “anger towards women,” whom he claimed were “all the same from fucking 18 to fucking 40 to fucking 90” and “trash.”Read full article Comments

In 1995, a Netscape employee wrote a hack in 10 days that now runs the Internet - 2時間前  Ars Technica

Thirty years ago today, Netscape Communications and Sun Microsystems issued a joint press release announcing JavaScript, an object scripting language designed for creating interactive web applications. The language emerged from a frantic 10-day sprint at pioneering browser company Netscape, where engineer Brendan Eich hacked together a working internal prototype during May of 1995. While the JavaScript language didn’t ship publicly until that September and didn’t reach a 1.0 release until March 1996, the descendants of Eich’s initial 10-day hack now run on approximately 98.9 percent of all web...moresites with client-side code, making JavaScript the dominant programming language of the web. It’s wildly popular; beyond the browser, JavaScript powers server backends, mobile apps, desktop software, and even some embedded systems. According to several surveys, JavaScript consistently ranks among the most widely used programming languages in the world. In crafting JavaScript, Netscape wanted a scripting language that could make webpages interactive, something lightweight that would appeal to web designers and non-professional programmers. Eich drew from several influences: The syntax looked like a trendy new programming language called Java to satisfy Netscape management, but its guts borrowed concepts from Scheme, a language Eich admired, and Self, which contributed JavaScript’s prototype-based object model.Read full article Comments

Trump wants tiny Japanese-style cars for US even as he cuts mpg goals - 5時間前  Ars Technica

It’s been less than a year into the second Trump administration, and to many outside observers, US government policies appear confusing or incoherent. Yesterday provided a good example from the automotive sector. As has been widely expected, the White House is moving ahead with plans to significantly erode fuel economy standards, beyond even the permissive levels that were considered OK during the first Trump term. Yet at the very announcement of that rollback, surrounded by compliant US automotive executives, the president decided to go off piste to declare his admiration for tiny Japanese Ke...morei cars, telling Transportation Secretary Sean Duffy to make them street-legal in the US. 50.4 mpg 40.4 mpg 34.5 mpg A little over a decade ago, the Obama administration announced new fuel economy standards for light trucks and cars that were meant to go into effect this year, bringing the corporate fleet fuel economy average up to 50.4 mpg. As you can probably tell, that didn’t happen. It wasn’t a popular move with automakers, and the first Trump administration ripped up those rules and instituted new, weaker targets of just 40.4 mpg by 2026.Read full article Comments

The NPU in your phone keeps improving—why isn’t that making AI better? - 8時間前  Ars Technica

Almost every technological innovation of the past several years has been laser-focused on one thing: generative AI. Many of these supposedly revolutionary systems run on big, expensive servers in a data center somewhere, but at the same time, chipmakers are crowing about the power of the neural processing units (NPU) they have brought to consumer devices. Every few months, it’s the same thing: This new NPU is 30 or 40 percent faster than the last one. That’s supposed to let you do something important, but no one really gets around to explaining what that is. Experts envision a future of secure...more, personal AI tools with on-device intelligence, but does that match the reality of the AI boom? AI on the “edge” sounds great, but almost every AI tool of consequence is running in the cloud. So what’s that chip in your phone even doing? What is an NPU? Companies launching a new product often get bogged down in superlatives and vague marketing speak, so they do a poor job of explaining technical details. It’s not clear to most people buying a phone why they need the hardware to run AI workloads, and the supposed benefits are largely theoretical.Read full article Comments

12 former FDA chiefs unite to say agency memo on vaccines is deeply stupid - 20時間前  Ars Technica

On Friday, Vinay Prasad—the Food and Drug Administration’s chief medical and scientific officer and its top vaccine regulator—emailed a stunning memo to staff that quickly leaked to the press. Without evidence, Prasad claimed COVID-19 vaccines have killed 10 children in the US, and, as such, he announced unilateral, sweeping changes to the way the agency regulates and approves vaccines, including seasonal flu shots. On Wednesday evening, a dozen former FDA commissioners, who collectively oversaw the agency for more than 35 years, responded to the memo with a scathing rebuke. Uniting to publish...more their response in the New England Journal of Medicine, the former commissioners said they were “deeply concerned” by Prasad’s memo, which they framed as a “threat” to the FDA’s work and a danger to Americans’ health. In his memo, Prasad called for abandoning the FDA’s current framework for updating seasonal flu shots and other vaccines, such as those for COVID-19. Those updates currently involve studies that measure well-characterized immune responses (called immunobridging studies). Prasad dismissed this approach as insufficient and, instead, plans to require expensive randomized trials, which can take months to years for each vaccine update.Read full article Comments

Great handling, advanced EV tech: We drive the 2027 BMW iX3 - 21時間前  Ars Technica

BMW provided flights from Washington, DC, to Malaga, Spain, and accommodation so Ars could drive the iX3. Ars does not accept paid editorial content. The new BMW iX3 is an important car for the automaker. It’s the first of a new series of vehicles that BMW is calling the Neue Klasse, calling back to a range of cars that helped define the brand in the 1960s. Then, as now, propulsion is provided by the best powertrain BMW’s engineers could design and build, wrapped in styling that heralds the company’s new look. Except now, that powertrain is fully electric, and the cabin features technology tha...moret would have been scarcely believable to the driver of a new 1962 BMW 1500. In fact, the iX3 is only half the story when it comes to BMW’s neue look for the Neue Klasse—there’s an all-electric 3 series sedan on the way, too. The sedan will surely appeal to enthusiasts, particularly the version that the M tuning arm has worked its magic upon, but you’ll have to wait until early 2026 to read about that stuff. Which makes sense: crossovers and SUVs—or “sports activity vehicles” in BMW-speak—are what the market wants these days, so that’s what comes first. The technical stuff As we learned earlier this summer, BMW leaned heavily into sustainability when it designed the iX3. There’s extensive use of recycled battery minerals, interior plastics, and aluminum, and the automaker has gone for a monomaterial approach where possible to make recycling the car a lot easier. There’s also an all-new EV powertrain, BMW’s sixth-generation. When it goes on sale here next summer, the launch model will be the iX3 50 xDrive, which pairs an asynchronous motor at the front axle and an electrically excited synchronous motor at the rear for a combined output of 463 hp (345 kW) and 475 lb-ft (645 Nm).Read full article Comments

Humans in southern Africa were an isolated population until recently - 1日前  Ars Technica

The fossil and genetic evidence agree that modern humans originated in Africa. The most genetically diverse human populations—the groups that have had the longest time to pick up novel mutations—live there today. But the history of what went on within Africa between our origins and the present day is a bit murky. That’s partly because DNA doesn’t survive long in the conditions typical of most of the continent, which has largely limited us to trying to reconstruct the past using data from present-day populations. The other part is that many of those present-day populations have been impacted by...more the vast genetic churn caused by the Bantu expansion, which left its traces across most of the populations south of the Sahara. But a new study has managed to extract genomes from ancient samples in southern Africa. While all of these are relatively recent, dating from after the end of the most recent glacial period, they reveal a distinct southern African population that was relatively large, outside of the range of previously described human variation, and it remained isolated until only about 1,000 years ago.Read full article Comments

Why won’t Steam Machine support HDMI 2.1? Digging in on the display standard drama. - 49分前  Ars Technica

When Valve announced its upcoming Steam Machine hardware last month, some eagle-eyed gamers may have been surprised to see that the official spec sheet lists support for HDMI 2.0 output, rather than the updated, higher-bandwidth HDMI 2.1 standard introduced in 2017. Now, Valve tells Ars that, while the hardware itself actually supports HDMI 2.1, the company is struggling to offer full support for that standard due to Linux drivers that are “still a work-in-progress on the software side.” As we noted last year, the HDMI Forum (which manages the official specifications for HDMI standards) has of...moreficially blocked any open source implementation of HDMI 2.1. That means the open source AMD drivers used by SteamOS can’t fully implement certain features that are specific to the updated output standard. “At this time an open source HDMI 2.1 implementation is not possible without running afoul of the HDMI Forum requirements,” AMD engineer Alex Deucher said at the time.Read full article Comments

OnePlus 15 finally gets FCC clearance after government shutdown delay—preorders live - 2時間前  Ars Technica

OnePlus is ready to sell its new flagship smartphone in the US weeks after it made the device official. Having now finally gotten Federal Communications Commission clearance, the OnePlus 15 is available for preorder. It’s currently only live on the OnePlus storefront, but the device will eventually come to Amazon and Best Buy as well. The OnePlus 15 launched in China earlier this year, and it was supposed to go on sale in the US a month ago. However, the longest US government shutdown on record got in the way. Most of the FCC’s functions were suspended during the weekslong funding lapse, which...more prevented the agency from certifying new wireless products. Without that approval, OnePlus could not begin selling the phone. Thus, it had no firm release date when the phone was officially unveiled for the US in early November. Interested parties can head to the OnePlus website to place an order. The base model starts at $900 with 12GB of RAM and 256GB of storage. This version is only available in black. If you want the Ultraviolet or Sand Storm (with the distinctive micro-arc oxidation finish), you’ll have to upgrade to the $1,000 version, which has 16GB of RAM and 512GB of storage.Read full article Comments

Welcome to “necroprinting”—3D printer nozzle made from mosquito’s proboscis - 4時間前  Ars Technica

Necrobotics is a field of engineering that builds robots out of a mix of synthetic materials and animal body parts. It has produced micro-grippers with pneumatically operated legs taken from dead spiders and walking robots based on deceased cockroaches. “These necrobotics papers inspired us to build something different,” said Changhong Cao, a mechanical engineering professor at the McGill University in Montreal, Canada. Cao’s team didn’t go for a robot—instead, it adapted a female mosquito proboscis to work as a nozzle in a super-precise 3D printer. And it worked surprisingly well. Fangs and s...moretings To find the right nozzle for their 3D necroprinting system, Cao’s team began with a broad survey of natural micro-dispensing tips. The researchers examined stingers of bees, wasps, and scorpions; the fangs of venomous snakes; and the claws of centipedes. All of those evolved to deliver a fluid to the target, which is roughly what a 3D printer’s nozzle does. But they all had issues. “Some were too curved and curved for high-precision 3D printing,” Cao explained. “Also, they were optimized for delivering pulses of venom, not for a steady, continuous flow, which is what you need for printing.”Read full article Comments

Maximum-severity vulnerability threatens 6% of all websites - 21時間前  Ars Technica

Security defenders are girding themselves in response to the disclosure of a maximum-severity vulnerability disclosed Wednesday in React Server, an open source package that’s widely used by websites and in cloud environments. The vulnerability is easy to exploit and allows hackers to execute malicious code on servers that run it. React is embedded in web apps running on servers so that remote devices render JavaScript and content more quickly and with fewer resources. React is used by an estimated 6 percent of all websites and 39 percent of cloud environments. When end users reload a page, Rea...morect allows servers to re-render only parts that have changed, a feature that drastically speeds up performance and lowers the computing resources required by the server. A perfect 10 Security firm Wiz said exploitation requires only a single HTTP request and had a “near-100% reliability” in its testing. Multiple software frameworks and libraries embed React implementations by default. As a result, even when apps don’t explicitly make use of React functionality, they can still be vulnerable, since the integration layer invokes the buggy code.Read full article Comments

Republicans drop Trump-ordered block on state AI laws from defense bill - 1日前  Ars Technica

Microsoft drops AI sales targets in half after salespeople miss their quotas - 1日前  Ars Technica

Microsoft has lowered sales growth targets for its AI agent products after many salespeople missed their quotas in the fiscal year ending in June, according to a report Wednesday from The Information. The adjustment is reportedly unusual for Microsoft, and it comes after the company missed a number of ambitious sales goals for its AI offerings. AI agents are specialized implementations of AI language models designed to perform multistep tasks autonomously rather than simply responding to single prompts. So-called “agentic” features have been central to Microsoft’s 2025 sales pitch: At its Buil...mored conference in May, the company declared that it has entered “the era of AI agents.” The company has promised customers that agents could automate complex tasks, such as generating dashboards from sales data or writing customer reports. At its Ignite conference in November, Microsoft announced new features like Word, Excel, and PowerPoint agents in Microsoft 365 Copilot, along with tools for building and deploying agents through Azure AI Foundry and Copilot Studio. But as the year draws to a close, that promise has proven harder to deliver than the company expected.Read full article Comments
