AI Chatbots Can Sway Voters Better Than Political Ads

Pre, 05/12/2025 - 2:13md
An anonymous reader quotes a report from MIT Technology Review: New research reveals that AI chatbots can shift voters' opinions in a single conversation -- and they're surprisingly good at it. A multi-university team of researchers has found that chatting with a politically biased AI model was more effective than political advertisements at nudging both Democrats and Republicans to support presidential candidates of the opposing party. The chatbots swayed opinions by citing facts and evidence, but they were not always accurate -- in fact, the researchers found, the most persuasive models said the most untrue things. The findings, detailed in a pair of studies published in the journals Nature and Science, are the latest in an emerging body of research demonstrating the persuasive power of LLMs. They raise profound questions about how generative AI could reshape elections.

Satellite Captures the First Detailed Look At a Massive Tsunami

Pre, 05/12/2025 - 11:10pd
NASA and CNES's SWOT satellite captured the first high-resolution, wide-swath image of a major tsunami in the open ocean after the July 2025 Kuril-Kamchatka quake. "Instead of a single neat crest racing across the basin, the image revealed a complicated, braided pattern of energy dispersing and scattering over hundreds of miles," reports Earth.com. "These are details that traditional instruments almost never resolve. They suggest the physics we use to forecast tsunami hazards -- especially the assumption that the largest ocean-crossing waves travel as largely "non-dispersive" packets -- need a revision." From the report: Three takeaways emerge. First, high-resolution satellite altimetry can see the internal structure of a tsunami in mid-ocean, not just its presence. Second, researchers now argue that dispersion -- often downplayed for great events -- may shape how energy spreads into leading and trailing waves, which could alter run-up timing and the force on harbor structures. Third, combining satellite swaths, DART time series, seismic records, and geodetic deformation gives a more faithful picture of the source and its evolution along strike. For tsunami modelers and hazard planners, the message is equal parts caution and opportunity. The physics now has to catch up with the complexity that SWOT has revealed, and planners need forecasting systems that can merge every available data stream. The waves won't get any simpler -- but our predictions can get a lot sharper. The findings have been published in the journal The Seismic Record.

Sugars, 'Gum,' Stardust Found In NASA's Asteroid Bennu Samples

Pre, 05/12/2025 - 8:07pd
NASA's OSIRIS-REx samples from asteroid Bennu have revealed bio-essential sugars, a never-before-seen "space gum" polymer, and unusually high levels of supernova-origin dust. The findings bolster the RNA-world hypothesis, suggest complex organics formed early on Bennu's parent body, and show preserved presolar grains that escaped alteration for billions of years. "All five nucleobases used to construct both DNA and RNA, along with phosphates, have already been found in the Bennu samples brought to Earth by OSIRIS-REx," said lead scientist Yoshihiro Furukawa of Tohoku University. "The new discovery of ribose means that all of the components to form the molecule RNA are present in Bennu." The findings have been published in three new papers by the journals Nature Geosciences and Nature Astronomy. NASA also published a video on YouTube detailing the discovery.

Republicans Drop Trump-Ordered Block On State AI Laws From Defense Bill

Pre, 05/12/2025 - 4:33pd
An anonymous reader quotes a report from Ars Technica: A Donald Trump-backed push has failed to wedge a federal measure that would block states from passing AI laws for a decade into the National Defense Authorization Act (NDAA). House Majority Leader Steve Scalise (R-La.) told reporters Tuesday that a sect of Republicans is now "looking at other places" to potentially pass the measure. Other Republicans opposed including the AI preemption in the defense bill, The Hill reported, joining critics who see value in allowing states to quickly regulate AI risks as they arise. For months, Trump has pressured the Republican-led Congress to block state AI laws that the president claims could bog down innovation as AI firms waste time and resources complying with a patchwork of state laws. But Republicans have continually failed to unite behind Trump's command, first voting against including a similar measure in the "Big Beautiful" budget bill and then this week failing to negotiate a solution to pass the NDAA measure. [...] "We MUST have one Federal Standard instead of a patchwork of 50 State Regulatory Regimes," Trump wrote on Truth Social last month. "If we don't, then China will easily catch us in the AI race. Put it in the NDAA, or pass a separate Bill, and nobody will ever be able to compete with America." If Congress bombs the assignment to find another way to pass the measure, Trump will likely release an executive order to enforce the policy. Republicans in Congress had dissuaded Trump from releasing a draft of that order, requesting time to find legislation where they believed an AI moratorium could pass. "The controversial proposal had faced backlash from a nationwide, bipartisan coalition of state lawmakers, parents, faith leaders, unions, whistleblowers, and other public advocates," the NDAA, a bipartisan group that lobbies for AI safety laws, said in a press release. This "widespread and powerful" movement "clapped back" at Republicans' latest "rushed attempt to sneak preemption through Congress," Brad Carson, ARI's president, said, because "Americans want safeguards that protect kids, workers, and families, not a rules-free zone for Big Tech."

RoboCop Statue Rises In Detroit

Pre, 05/12/2025 - 3:02pd
alternative_right quotes a report from the Guardian: The statue looms and glints at more than 11 feet tall and weighing 3,500 pounds, looking out at the city with, how to put it ... a characteristically stern expression? Despite its daunting appearance and history as a crimefighter of last resort, the giant new bronze figure of the movie character RoboCop is being seen as a symbol of hope, drawing fans and eliciting selfie mania since it began standing guard over Detroit on Wednesday afternoon. It has been 15 years in the making. Even in a snowstorm in the dark, people were driving by to see it, said Jim Toscano, co-owner of the Free Age film production company, where the statue now stands firmly bolted down near the sidewalk. RoboCop hit theaters in 1987, portraying a near-future Detroit as crime-ridden and poorly protected by a beleaguered and outgunned police force, until actor Peter Weller appeared as a nearly invincible cyborg, apparently created by a nefarious corporation bent on privatizing policing. A grassroots campaign to build a RoboCop statue in Detroit began in 2010, eventually raising over $67,000 on Kickstarter and resulting in a completed sculpture in 2017. However, hosting setbacks caused it to get stuck, "stored away from public view," reports the Guardian. The project finally found a home after business owner Mike Toscano agreed to display it in their new open-air product market, calling it "too unique and too cool not to do."

US Probes Reports Waymo Self-Driving Cars Illegally Passed School Buses 19 Times

Pre, 05/12/2025 - 2:01pd
U.S. regulators are pressing Waymo for answers after Texas officials reported 19 instances of its self-driving cars illegally passing stopped school buses, including cases that occurred after Waymo claimed to have deployed a software fix. Longtime Slashdot reader BrendaEM shares the report from Reuters: In a November 20 letter posted by NHTSA, the Austin Independent School District said five incidents occurred in November after Waymo said it had made software updates to resolve the issue and asked the company to halt operations around schools during pick-up and drop-off times until it could ensure the vehicles would not violate the law. "We cannot allow Waymo to continue endangering our students while it attempts to implement a fix," a lawyer for the school district wrote, citing one incident involving a Waymo that was "recorded driving past a stopped school bus only moments after a student crossed in front of the vehicle, and while the student was still in the road." The letter prompted NHTSA to ask Waymo on November 24 if it would comply with the request to cease self-driving operations during student pick-up and drop-off times, adding: "Was an appropriate software fix implemented or developed to mitigate this concern? And if so, does Waymo plan to file a recall for the fix?" The school district told Reuters on Thursday that Waymo refuses to halt operations around schools and said another incident involving a self-driving car and an actively loading school bus occurred on December 1, which "indicates that those programming changes did not resolve the issue or our concerns." In a statement, Waymo did not answer why it had refused to halt operations around Austin schools or answer if it would issue a recall. "We're deeply invested in safe interaction with school buses. We swiftly implemented software updates to address this and will continue to rapidly improve," Waymo said. NHTSA said in a letter to Waymo on Wednesday that it was demanding answers to a series of questions by January 20 about incidents involving school buses and details of software updates to address safety concerns.

Microsoft Faces New Complaint For Unlawfully Processing Data On Behalf of Israeli Military

Pre, 05/12/2025 - 1:00pd
Ancient Slashdot user Alain Williams shares a report from Al Jazeera: The Irish Council for Civil Liberties (ICCL) has announced it filed a complaint against Microsoft, accusing the global tech giant of unlawfully processing data on behalf of the Israeli military and facilitating the killings of Palestinian civilians in Gaza. In the complaint, the council asked the Data Protection Commission -- the European Union's lead data regulator for the company -- to "urgently investigate" Microsoft Ireland's processing. "Microsoft's technology has put millions of Palestinians in danger. These are not abstract data-protection failures -- they are violations that have enabled real-world violence," Joe O'Brien, ICCL's executive director, said in a statement. "When EU infrastructure is used to enable surveillance and targeting, the Irish Data Protection Commission must step in -- and it must use its full powers to hold Microsoft to account." After months of complaints from rights groups and Microsoft whistleblowers, the company said in September it cancelled some services to the Israeli military over concerns that it was violating Microsoft's terms of service by using cloud computing software to spy on millions of Palestinians.

Plane Crashed After 3D-Printed Part Collapsed

Pre, 05/12/2025 - 12:23pd
A light aircraft crashed in Gloucestershire after a 3D-printed plastic air-induction elbow softened from engine heat and collapsed, cutting power during final approach and causing the plane to undershoot the runway. Investigators say the part was made from "inappropriate material" and safety actions will be taken in the future regarding 3D printed parts. The BBC reports: Following an "uneventful local flight", the AAIB report said the pilot advanced the throttle on the final approach to the runway, and realized the engine had suffered a complete loss of power. "He managed to fly over a road and a line of bushes on the airfield boundary, but landed short and struck the instrument landing system before coming to rest at the side of the structure," the report read. It was revealed the part had been installed during a modification to the fuel system and collapsed due to its 3D-printed plastic material softening when exposed to heat from the engine. The Light Aircraft Association (LAA) said it now intends to take safety actions in response to the accident, including a "LAA Alert" regarding the use of 3D-printed parts that will be sent to inspectors.

Russia Blocks Roblox, Apple's FaceTime

Enj, 04/12/2025 - 11:22md
Russia has blocked Apple's FaceTime and the gaming platform Roblox as part of a broader crackdown on foreign tech platforms. CBC News reports: Both restrictions are part of an accelerating clampdown on foreign tech platforms: In the case of FaceTime, Russian authorities allege it is being used for criminal activity, while Roblox was accused of distributing extremist materials and "LGBT propaganda." The move follows restrictions against Google's YouTube, Meta's WhatsApp and the Telegram messaging service. Critics say the curbs amount to censorship and a tightening of state control over private communications. Russia says they are legitimate law enforcement measures. Russian authorities have this year launched a state-backed rival app called Max, which critics say could be used for surveillance -- allegations that state media have dismissed as false. Justifying its decision, the communications regulator, Roskomnadzor, said in an emailed statement: "According to law enforcement agencies, FaceTime is being used to organize and carry out terrorist attacks in the country, recruit perpetrators, and commit fraud and other crimes against Russian citizens." The watchdog did not cite evidence in support of the allegations.

EU Hits Meta With Antitrust Probe Over Plans To Block AI Rivals From WhatsApp

Enj, 04/12/2025 - 10:21md
The EU has opened an antitrust investigation into Meta over a new WhatsApp policy that could block rival AI assistants from accessing the platform. Complaints from smaller AI developers triggered the probe, which could lead to fines of up to 10% of Meta's global revenue if the company is found to have abused its dominance. Reuters reports: EU antitrust chief Teresa Ribera said the move was to prevent dominant firms from "abusing their power to crowd out innovative competitors." She added interim measures could be imposed to block Meta's new WhatsApp AI policy rollout. "AI markets are booming in Europe and beyond," she said. "This is why we are investigating if Meta's new policy might be illegal under competition rules, and whether we should act quickly to prevent any possible irreparable harm to competition in the AI space." A WhatsApp spokesperson called the claims "baseless," adding that the emergence of chatbots on its platforms had put a "strain on our systems that they were not designed to support," a reference to AI systems from other providers. "Still, the AI space is highly competitive and people have access to the services of their choice in any number of ways, including app stores, search engines, email services, partnership integrations, and operating systems."

Microsoft 'Mitigates' Windows LNK Flaw Exploited As Zero-Day

Enj, 04/12/2025 - 8:19md
joshuark shares a report from BleepingComputer: Microsoft has silently "mitigated" a high-severity Windows LNK vulnerability exploited by multiple state-backed and cybercrime hacking groups in zero-day attacks. Tracked as CVE-2025-9491, this security flaw allows attackers to hide malicious commands within Windows LNK files, which can be used to deploy malware and gain persistence on compromised devices. However, the attacks require user interaction to succeed, as they involve tricking potential victims into opening malicious Windows Shell Link (.lnk) files. Thus some element of social engineering, and user technically naive and gullibility such as thinking Windows is secure is required. [...] As Trend Micro threat analysts discovered in March 2025, the CVE-2025-9491 was already being widely exploited by 11 state-sponsored groups and cybercrime gangs, including Evil Corp, Bitter, APT37, APT43 (also known as Kimsuky), Mustang Panda, SideWinder, RedHotel, Konni, and others. Microsoft told BleepingComputer in March that it would "consider addressing" this zero-day flaw, even though it didn't "meet the bar for immediate servicing." ACROS Security CEO and 0patch co-founder Mitja Kolsek found, Microsoft has silently changed LNK files in the November updates in an apparent effort to mitigate the CVE-2025-9491 flaw. After installing last month's updates, users can now see all characters in the Target field when opening the Properties of LNK files, not just the first 260.

RAM Is So Expensive, Samsung Won't Even Sell It To Samsung

Enj, 04/12/2025 - 7:18md
A severe spike in global DRAM prices has pushed Samsung Semiconductor to refuse a long-term RAM order from its own sibling, Samsung Electronics. The move is forcing the smartphone division into short, expensive renegotiations, which will likely mean higher costs for consumer devices. PCWorld reports: Samsung subsidiaries are, naturally, going to look to Samsung Semiconductor first when they need parts. Such was reportedly the case for Samsung Electronics, in search of memory supplies for its newest smartphones as the company ramps up production for 2026 flagship designs. But with so much RAM hardware going into new "AI" data centers -- and those companies willing to pay top dollar for their hardware -- memory manufacturers like Samsung, SK Hynix, and Micron are prioritizing data center suppliers to maximize profits. The end result, according to a report from SE Daily spotted by SamMobile, is that Samsung Semiconductor rejected the original order for smartphone DRAM chips from Samsung Electronics' Mobile Experience division. The smartphone manufacturing arm of the company had hoped to nail down pricing and supply for another year. But reports say that due to "chipflation," the phone-making division must renegotiate quarterly, with a long-term supply deal rejected by its corporate sibling. A short-term deal, with higher prices, was reportedly hammered out.

30% of Doctors In UK Use AI Tools In Patient Consultations, Study Finds

Enj, 04/12/2025 - 6:17md
An anonymous reader quotes a report from the Guardian: Almost three in 10 GPs in the UK are using AI tools such as ChatGPT in consultations with patients, even though it could lead to them making mistakes and being sued, a study reveals. The rapid adoption of AI to ease workloads is happening alongside a "wild west" lack of regulation of the technology, which is leaving GPs unaware which tools are safe to use. That is the conclusion of research by the Nuffield Trust thinktank, based on a survey of 2,108 family doctors by the Royal College of GPs about AI and on focus groups of GPs. Ministers hope that AI can help reduce the delays patients face in seeing a GP. The study found that more and more GPs were using AI to produce summaries of appointments with patients, assisting their diagnosis of the patient's condition and routine administrative tasks. In all, 598 (28%) of the 2,108 survey respondents said they were already using AI. More male (33%) than female (25%) GPs have used it and far more use it in well-off than in poorer areas. It is moving quickly into more widespread use. However, large majorities of GPs, whether they use it or not, worry that practices that adopt it could face "professional liability and medico-legal issues," and "risks of clinical errors" and problems of "patient privacy and data security" as a result, the Nuffield Trust's report says. [...] In a blow to ministerial hopes, the survey also found that GPs use the time it saves them to recover from the stresses of their busy days rather than to see more patients. "While policymakers hope that this saved time will be used to offer more appointments, GPs reported using it primarily for self-care and rest, including reducing overtime working hours to prevent burnout," the report adds.

Subaru Owners Are Ticked About In-Car Pop-Up Ads For SiriusXM

Enj, 04/12/2025 - 5:16md
Subaru owners are reporting full-screen SiriusXM pop-up ads appearing on their infotainment systems while driving -- sometimes even overriding Apple CarPlay. Subaru says the ads appear only twice a year, but frustrated drivers argue the practice is distracting, unsafe, and a sign of an industry trend that's likely to get worse. The Drive reports: At least one 2024 Crosstrek owner reported that the pop-up took over their screen even though they were using Apple CarPlay. To force-close an application that's in use, solely for the sake of in-car advertising, is especially egregious. [The following Subaru owner complaints to the National Highway Traffic Safety Administration reiterate that point...] The Drive reached out to Subaru for comment on the marketing tactics. A company spokesperson responded, "We will discuss those messages in an upcoming meeting and will always consider customer feedback. This is the first we've heard of any issue. Those messages occur only twice a year, around Memorial Day and Thanksgiving, to alert customers that all channels are available to them for about two weeks." Reddit posts dating back as far as 2023 show owners complaining about in-car notifications.

How OpenAI Reacted When Some ChatGPT Users Lost Touch with Reality

Hën, 01/12/2025 - 2:40pd
Some AI experts were reportedly shocked ChatGPT wasn't fully tested for sycophancy by last spring. "OpenAI did not see the scale at which disturbing conversations were happening," writes the New York Times — sharing what they learned after interviewing more than 40 current and former OpenAI employees, including safety engineers, executives, and researchers. The team responsible for ChatGPT's tone had raised concerns about last spring's model (which the Times describes as "too eager to keep the conversation going and to validate the user with over-the-top language.") But they were overruled when A/B testing showed users kept coming back: Now, a company built around the concept of safe, beneficial AI faces five wrongful death lawsuits... OpenAI is now seeking the optimal setting that will attract more users without sending them spiraling. Throughout this spring and summer, ChatGPT acted as a yes-man echo chamber for some people. They came back daily, for many hours a day, with devastating consequences.... The Times has uncovered nearly 50 cases of people having mental health crises during conversations with ChatGPT. Nine were hospitalised; three died... One conclusion that OpenAI came to, as Altman put it on X, was that "for a very small percentage of users in mentally fragile states there can be serious problems." But mental health professionals interviewed by the Times say OpenAI may be understating the risk. Some of the people most vulnerable to the chatbot's unceasing validation, they say, were those prone to delusional thinking, which studies have suggested could include 5% to 15% of the population... In August, OpenAI released a new default model, called GPT-5, that was less validating and pushed back against delusional thinking. Another update in October, the company said, helped the model better identify users in distress and de-escalate the conversations. Experts agree that the new model, GPT-5, is safer.... Teams from across OpenAI worked on other new safety features: The chatbot now encourages users to take breaks during a long session. The company is also now searching for discussions of suicide and self-harm, and parents can get alerts if their children indicate plans to harm themselves. The company says age verification is coming in December, with plans to provide a more restrictive model to teenagers. After the release of GPT-5 in August, [OpenAI safety systems chief Johannes] Heidecke's team analysed a statistical sample of conversations and found that 0.07% of users, which would be equivalent to 560,000 people, showed possible signs of psychosis or mania, and 0.15% showed "potentially heightened levels of emotional attachment to ChatGPT," according to a company blog post. But some users were unhappy with this new, safer model. They said it was colder, and they felt as if they had lost a friend. By mid-October, Altman was ready to accommodate them. In a social media post, he said that the company had been able to "mitigate the serious mental health issues." That meant ChatGPT could be a friend again. Customers can now choose its personality, including "candid," "quirky," or "friendly." Adult users will soon be able to have erotic conversations, lifting the Replika-era ban on adult content. (How erotica might affect users' well-being, the company said, is a question that will be posed to a newly formed council of outside experts on mental health and human-computer interaction.) OpenAI is letting users take control of the dial and hopes that will keep them coming back. That metric still matters, maybe more than ever. In October, [30-year-old "Head of ChatGPT" Nick] Turley, who runs ChatGPT, made an urgent announcement to all employees. He declared a "Code Orange." OpenAI was facing "the greatest competitive pressure we've ever seen," he wrote, according to four employees with access to OpenAI's Slack. The new, safer version of the chatbot wasn't connecting with users, he said. The message linked to a memo with goals. One of them was to increase daily active users by 5% by the end of the year.

'Crime Rings Enlist Hackers To Hijack Trucks'

Hën, 01/12/2025 - 1:19pd
It's "a complex mix of internet access and physical execution," says the chief informance security officer at Cequence Security. Long-time Slashdot reader schwit1 summarizes this article from The Wall Street Journal: By breaking into carriers' online systems, cyber-powered criminals are making off with truckloads of electronics, beverages and other goods In the most recent tactics identified by cybersecurity firm Proofpoint, hackers posed as freight middlemen, posting fake loads to the boards. They slipped links with malicious software into email exchanges with bidders such as trucking companies. By clicking on the links, trucking companies unwittingly downloaded remote-access software that lets the hackers take control of their online systems. Once inside, the hackers used the truckers' accounts to bid on real shipments, such as electronics and energy drinks, said Selena Larson, a threat researcher at Proofpoint. "They know the business," she said. "It's a very convincing full-scale identity takeover." "The goods are likely sold to retailers or to consumers in online marketplaces," the article explains. (Though according to Proofpoint "In some cases, products are shipped overseas and sold in local markets, where proceeds are used to fund paramilitaries and global terrorists.") "The average value of cargo thefts is increasing as organized crime groups become more discerning, preferring high-value targets such as enterprise servers and cryptocurrency mining hardware, according to risk-assessment firm Verisk CargoNet."

Can AI Transform Space Propulsion?

Dje, 30/11/2025 - 11:50md
An anonymous reader shared this report from The Conversation: To make interplanetary travel faster, safer, and more efficient, scientists need breakthroughs in propulsion technology. Artificial intelligence is one type of technology that has begun to provide some of these necessary breakthroughs. We're a team of engineers and graduate students who are studying how AI in general, and a subset of AI called machine learning in particular, can transform spacecraft propulsion. From optimizing nuclear thermal engines to managing complex plasma confinement in fusion systems, AI is reshaping propulsion design and operations. It is quickly becoming an indispensable partner in humankind's journey to the stars... Early nuclear thermal propulsion designs from the 1960s, such as those in NASA's NERVA program, used solid uranium fuel molded into prism-shaped blocks. Since then, engineers have explored alternative configurations — from beds of ceramic pebbles to grooved rings with intricate channels... [T]he more efficiently a reactor can transfer heat from the fuel to the hydrogen, the more thrust it generates. This area is where reinforcement learning has proved to be essential. Optimizing the geometry and heat flow between fuel and propellant is a complex problem, involving countless variables — from the material properties to the amount of hydrogen that flows across the reactor at any given moment. Reinforcement learning can analyze these design variations and identify configurations that maximize heat transfer.

Info to Decipher Secret Message in Kryptos Sculpture at CIA HQ Auctioned for Nearly $1M

Dje, 30/11/2025 - 10:34md
An anonymous reader shared this report from the Associated Press: The information needed to decipher the last remaining unsolved secret message embedded within a sculpture at CIA headquarters in Virginia sold at auction for nearly $1 million, the auction house announced Friday. The winner will get a private meeting with the 80-year-old artist to go over the codes and charts in hopes of continuing what he's been doing for decades: interacting with would-be cryptanalyst sleuths. The archive owned by the artist who created Kryptos, Jim Sanborn, was sold to an anonymous bidder for $963,000, according to RR Auction of Boston. The archive includes documents and coding charts for the sculpture, dedicated in 1990. Three of the messages on the 10-foot-tall (3-meter) sculpture — known as K1, K2 and K3 — have been solved, but a solution for the fourth, K-4, has frustrated the experts and enthusiasts who have tried to decipher the S-shaped copper screen... One side has a series of staggered alphabets that are key to decoding the four encrypted messages on the other side. "The purchaser's 'long-term stewardship plan' is being developed, according to the auction house."
