Google To Let 'Superfans' Test In-Development Pixel Phones

Hën, 20/10/2025 - 9:25md
Google plans to let Pixel smartphone enthusiasts test out the company's next handset ahead of its public introduction. From a report: Google has invited members of its "Superfans" group to apply to test future Pixel hardware, asking entrants to profess their knowledge and passion for the brand in hopes of being able to beta test forthcoming products. Consumer tech companies often let small groups of customers try out unreleased products under strict secrecy to gather feedback during development. But it's incredibly rare for a company of Google's size to do it with something as high-profile as the Pixel lineup. The search giant will select 15 people from the pool of entrants, and winners must all sign a non-disclosure agreement to receive devices, according to official rules for the contest reviewed by Bloomberg News. "The Trusted Tester program is an opportunity to provide feedback and help shape a Pixel phone currently in development," the document reads.

OpenAI's 'Embarrassing' Math

Hën, 20/10/2025 - 8:45md
An anonymous reader writes: "Hoisted by their own GPTards." That's how Meta's Chief AI Scientist Yann LeCun described the blowback after OpenAI researchers did a victory lap over GPT-5's supposed math breakthroughs. Google DeepMind CEO Demis Hassabis added, "this is embarrassing." The Decoder reports that in a since-deleted tweet, OpenAI VP Kevin Weil declared that "GPT-5 found solutions to 10 (!) previously unsolved Erdos problems and made progress on 11 others." ("Erdos problems" are famous conjectures posed by mathematician Paul Erdos.) However, mathematician Thomas Bloom, who maintains the Erdos Problems website, said Weil's post was "a dramatic misrepresentation" -- while these problems were indeed listed as "open" on Bloom's website, he said that only means, "I personally am unaware of a paper which solves it." In other words, it's not accurate to claim GPT-5 was able to solve previously unsolved problems. Instead, Bloom wrote, "GPT-5 found references, which solved these problems, that I personally was unaware of."

The Sims Mobile is Shutting Down Next Year

Hën, 20/10/2025 - 8:08md
The Sims is in a period of transition -- and as part of that, the ongoing mobile version will be shutting down in a few months. From a report: EA announced that today's update for The Sims Mobile will be its last, and that on January 20th, 2026 the game "will no longer be accessible to play and will be sunset." The mobile iteration of the franchise first launched in 2018, and has seen more than 50 updates since then. EA says that starting today players will no longer be able to spend real money in the game, and that it will be delisted on both iOS and Android tomorrow before the servers shut down completely next year, making it entirely unplayable.

China Accuses NSA of Hacking National Timekeeping Agency

Hën, 20/10/2025 - 7:31md
China says it has uncovered what it describes as irrefutable evidence of American government cyber attacks targeting the National Time Service Center. The Ministry of State Security said the National Security Agency exploited vulnerabilities in employees' mobile phones beginning March 25, 2022, and later used stolen login credentials to access the center's computers starting April 18, 2023. The facility in Xi'an provides high-precision timekeeping service for the government, civil society, and various industries. It also supplies data used to calculate international standard time. Chinese authorities said investigators found that private servers worldwide were employed to conceal the attacks' origin. The accusations emerge against a backdrop of mutual cyber-espionage claims between Washington and Beijing. Western governments and companies have repeatedly blamed Chinese hackers for intrusions in recent years.

Experts Hail 'Remarkable' Success of Electronic Implant in Restoring Sight

Hën, 20/10/2025 - 6:51md
An electronic eye implant has restored reading ability to patients blinded by geographic atrophy, a form of dry age-related macular degeneration. Results published Monday in the New England Journal of Medicine showed that 84% of trial participants regained the ability to read letters, numbers, and words after receiving the Prima device. The microchip measures two millimetres by two millimetres and is implanted beneath the center of the retina. Patients wear augmented reality glasses containing a camera that projects images onto the chip. The device converts light into electrical pulses transmitted to the brain. Frank Holz, the study's lead author and chair of ophthalmology at the University Hospital of Bonn, called the implant "a paradigm shift in treating late-stage age-related macular degeneration." Mahi Muqit, a consultant at Moorfields Eye Hospital in London, said the trial enabled "meaningful central vision restoration, which has never been done before." The procedure takes less than two hours and requires intensive rehabilitation. Science Corporation, which manufactures the device, has applied for clinical authorization in the United States and Europe.

Peanut Allergies Have Plummeted in Children, Study Shows

Hën, 20/10/2025 - 6:01md
Food allergies in children dropped sharply in the years after new guidelines encouraged parents to introduce infants to peanuts, a study has found. The New York Times: For decades, as food allergy rates climbed, experts recommended that parents avoid exposing their infants to common allergens. But a landmark trial in 2015 found that feeding peanuts to babies could cut their chances of developing an allergy by over 80%. [non-paywalled source.] In 2017, the National Institute of Allergy and Infectious Diseases formally recommended the early-introduction approach and issued national guidelines. The new study, published Monday in the journal Pediatrics, found that food allergy rates in children under 3 fell after those guidelines were put into place -- dropping to 0.93% between 2017 and 2020, from 1.46% between 2012 and 2015. That's a 36% reduction in all food allergies, driven largely by a 43% drop in peanut allergies. The study also found that eggs overtook peanuts as the No. 1 food allergen in young children. The study did not examine what infants ate, so it does not show that the guidelines caused the decline. Still, the data is promising. While all food allergies can be dangerous, 80% of people never outgrow one.

India Draft Plan Reveals $21 Trillion Net-Zero Investment Need

Hën, 20/10/2025 - 5:22md
India will need as much as $21 trillion to achieve its climate goals and lift its population out of poverty, according to a draft government plan seen by Bloomberg. From the report: The estimate offers a first glimpse of how the country intends to live up to its target of net zero emissions by 2070. The updated scenario implies hitting peak emissions in 2045, which is a decade earlier than the current trajectory. India is already being severely battered by the fallout of climate change, as deadly floods and heat waves become more destructive each year. But the need to mitigate the emissions that feed climate change has historically been at odds with India's priorities of economic growth and energy security, with the latter still mostly provided through coal. The new plan shows India will seek to achieve climate and economic development goals simultaneously, with low-carbon options envisaged for much of its yet-to-be-built residential and industrial infrastructure.

Are We Living in a Golden Age of Stupidity?

Hën, 20/10/2025 - 4:40md
Test scores across OECD countries peaked around 2012 and have declined since. IQ scores in many developed countries appear to be falling after rising throughout the twentieth century. Nataliya Kosmyna at MIT's Media Lab began noticing changes around two years ago when strangers started emailing her to ask if using ChatGPT could alter their brains. She posted a study in June tracking brain activity in 54 students writing essays. Those using ChatGPT showed significantly less activity in networks tied to cognitive processing and attention compared to students who wrote without digital help or used only internet search engines. Almost none could recall what they had written immediately after submitting their work. She received more than 4,000 emails afterward. Many came from teachers who reported students producing passable assignments without understanding the material. A British survey found that 92% of university students now use AI and roughly 20% have used it to write all or part of an assignment. Independent research has found that more screen time in schools correlates with worse results. Technology companies have designed products to be frictionless, removing the cognitive challenges brains need to learn. AI now allows users to outsource thinking itself.

AWS Outage Takes Thousands of Websites Offline for Three Hours

Hën, 20/10/2025 - 4:00md
AWS experienced a three-hour outage early Monday morning that disrupted thousands of websites and applications across the globe. The cloud computing provider reported DNS problems with DynamoDB in its US-EAST-1 region in northern Virginia starting at 12:11 a.m. Pacific time. Over 4 million users reported issues, according to Downdetector. Snapchat saw reports spike from more than 22,000 to around 4,000 as systems recovered. Roblox dropped from over 12,600 complaints to fewer than 500. Reddit and the financial platform Chime remained affected longer. Perplexity, Coinbase and Robinhood attributed their platform disruptions directly to AWS. Gaming platforms including Fortnite, Clash Royale and Clash of Clans went offline. Signal confirmed the messaging app was down. In Britain, Lloyd Bank, Bank of Scotland, Vodafone, BT, and the HMRC website faced problems. United Airlines reported disrupted access to its app and website overnight. Some internal systems were temporarily affected. Delta experienced a small number of minor flight delays. By 3:35 a.m. Pacific time, AWS said the issue had been fully mitigated. Most service operations were succeeding normally though some requests faced throttling during final resolution. AWS holds roughly one-third of the cloud infrastructure market ahead of Microsoft and Google.

Should We Edit Nature to Help It Survive Climate Change?

Hën, 20/10/2025 - 1:34md
A recent article in Noema magazines explores the issues in "editing nature to fix our failures." "It turns out playing God is neither difficult nor expensive," the article points out. "For about $2,000, I can go online and order a decent microscope, a precision injection rig, and a vial of enough CRISPR-Cas9 — an enzyme-based genome-editing tool — to genetically edit a few thousand fish embryos..." So when going beyond the kept-in-captivity Dire Wolf to the possibility of bringing back forests of the American chestnut tree, "The process is deceptively simple; the implications are anything but..." If scientists could use CRISPR to engineer a more heat-tolerant coral, it would give coral a better chance of surviving a marine environment made warmer by climate change. It would also keep the human industries that rely on reefs afloat. But should we edit nature to fix our failures? And if we do, is it still natural...? Evolution is not keeping pace with climate change, so it is up to us to give it an assist [according to Christopher Preston, an environmental philosopher from the University of Montana, who wrote a book on CRISPR called "Ma href="https://mitpress.mit.edu/9780262537094/the-synthetic-age/">The Synthetic Age."] In some cases, the urgency is so great that we may not have time to waste. "There's no doubt there are times when you have to act," Preston continued. "Corals are a case where the benefits of reefs are just so enormous that keeping some alive, even if they're genetically altered, makes the risks worth it." Kate Quigley, a molecular ecologist and a principal research scientist at Australia's Minderoo Foundation, says "Engineering the ocean, or the atmosphere, or coral is not something to be taken lightly. Science is incredible. But that doesn't mean we know everything and what the unintended consequences might be." Phillip Cleves, a principal investigator at the Carnegie Institute for Science's embryology department, is already researching whether coral could be bioengineered to be more tolerant to heat. But both of them have concerns: For all the research Quigley and Cleves have dedicated to climate-proofing coral, neither wants to see the results of their work move from experimentation in the lab to actual use in the open ocean. Needing to do so would represent an even greater failure by humankind to protect the environment that we already have. And while genetic editing and selective breeding offer concrete solutions for helping some organisms adapt, they will never be powerful enough to replace everything lost to rising water temperatures. "I will try to prepare for it, but the most important thing we can do to save coral is take strong action on climate change," Quigley told me. "We could pour billions and billions of dollars — in fact, we already have — into restoration, and even if, by some miracle, we manage to recreate the reef, there'd be other ecosystems that would need the same thing. So why can't we just get at the root issue?" And then there's the blue-green algae dilemma: George Church, the Harvard Medical School professor of genetics behind Colossal's dire wolf project, was part of a team that successfully used CRISPR to change the genome of blue-green algae so that it could absorb up to 20% more carbon dioxide via photosynthesis. Silicon Valley tech incubator Y Combinator seized on the advance to call for scaled-up proposals, estimating that seeding less than 1% of the ocean's surface with genetically engineered phytoplankton would sequester approximately 47 gigatons of CO2 a year, more than enough to reverse all of last year's worldwide emissions. But moving from deploying CRISPR for species protection to providing a planetary service flips the ethical calculus. Restoring a chestnut forest or a coral reef preserves nature, or at least something close to it. Genetically manipulating phytoplankton and plants to clean up after our mistakes raises the risk of a moral hazard. Do we have the right to rewrite nature so we can perpetuate our nature-killing ways?

'The AI Revolution's Next Casualty Could Be the Gig Economy'

Hën, 20/10/2025 - 9:34pd
"The gig economy is facing a reckoning," argues Business Insider's BI Today newsletter." Two stories this past week caught my eye. Uber unveiled a new way for its drivers to earn money. No, not by giving rides, but by helping train the ride-sharing company's AI models instead. On the same day, Waymo announced a partnership with DoorDash to test driverless grocery and meal deliveries. Both moves point toward the same future: one where the very workers who built the gig economy may soon find themselves training the technology that replaces them. Uber's new program allows drivers to earn cash by completing microtasks, such as taking photos and uploading audio clips, that aim to improve the company's AI systems. For drivers, it's a way to diversify income. For Uber, it's a way to accelerate its automated future. There's an irony here. By helping Uber strengthen its AI, drivers could be accelerating the very driverless world they fear... Uber already offers autonomous rides in Waymo vehicles in Atlanta and Austin, and plans to expand. Meanwhile, Waymo is rolling out its pilot partnership with DoorDash [for driverless grocery/meal deliveries] starting in Phoenix.

Windows 11 Update Breaks Recovery Environment, Making USB Keyboards and Mice Unusable

Hën, 20/10/2025 - 6:54pd
"Windows Recovery Environment (RE), as the name suggests, is a built-in set of tools inside Windows that allow you to troubleshoot your computer, including booting into the BIOS, or starting the computer in safe mode," writes Tom's Hardware. "It's a crucial piece of software that has now, unfortunately, been rendered useless (for many) as part of the latest Windows update." A new bug discovered in Windows 11's October build, KB5066835, makes it so that your USB keyboard and mouse stop working entirely, so you cannot interact with the recovery UI at all. This problem has already been recognized and highlighted by Microsoft, who clarified that a fix is on its way to address this issue. Any plugged-in peripherals will continue to work just fine inside the actual operating system, but as soon as you go into Windows RE, your USB keyboard and mouse will become unresponsive. It's important to note that if your PC fails to start-up for any reason, it defaults to the recovery environment to, you know, recover and diagnose any issues that might've been preventing it from booting normally. Note that those hanging onto old PS/2-connector equipped keyboards and mice seem to be unaffected by this latest Windows software gaffe.

Was the Web More Creative and Human 20 Years Ago?

Hën, 20/10/2025 - 4:34pd
Readers in 2025 "may struggle to remember the optimism of the aughts, when the internet seemed to offer endless possibilities for virtual art and writing that was free..." argues a new review at Bookforum. "The content we do create online, if we still create, often feels unreflectively automatic: predictable quote-tweet dunks, prefabricated poses on Instagram, TikTok dances that hit their beats like clockwork, to say nothing of what's literally thoughtlessly churned out by LLM-powered bots." They write that author Joanna Walsh "wants us to remember how truly creative, and human, the internet once was," in the golden age of user-generated content — and funny cat picture sites like I Can Has Cheezburger: I Can Has Cheezburger... was an amateur project, an outlet for tech professionals who wanted an easier way to exchange cute cat pics after a hard day at work. In Amateurs!: How We Built Internet Culture and Why It Matters, Walsh documents how unpaid creative labor is the basis for almost everything that's good (and much that's bad) online, including the open-source code Linux, developed by Linus Torvalds when he was still in school ("just as a hobby, won't be big and professional"), and even, in Walsh's account, the World Wide Web itself. The platforms that emerged in the 2000s as "Web 2.0," including Facebook, YouTube, Reddit, and Twitter, allowed anyone to experiment in a space that had been reserved for coders and hackers, making the internet interactive even for the inexpert and virtually unlimited in potential audience. The explosion in amateur creativity that followed took many forms, from memes to tweeted one-liners to diaristic blogs to durational digital performances to sloppy Photoshops to the formal and informal taxonomic structures — wikis, neologisms, digitally native dialects... [U]ser-generated content was also, at bottom, about the bottom line, a business model sold to us under the guise of artistic empowerment. Even referring to an anonymous amateur as a "user," Walsh argues, cedes ground: these platforms are populated by producers, but their owners see us as, and turn us into, "helpless addicts." For some, online amateurism translated to professional success, a viral post earning an author a book deal, or a reputation as a top commenter leading to a staff writing job on a web publication... But for most, these days, participation in the online attention economy feels like a tax, or maybe a trickle of revenue, rather than free fun or a ticket to fame. The few remaining professionals in the arts and letters have felt pressured to supplement their full-time jobs with social media self-promotion, subscription newsletters, podcasts, and short-form video. On what was once called Twitter, users can pay, and sometimes get paid, to post with greater reach... The chapters are bookended by an introduction on the early promise of 2004 and a coda on the defeat of 2025 and supplemented by an appendix with a straightforward timeline of the major events and publications that serve as the book's touchstones... The online spaces where amateur content creators once "created and steered online culture" have been hollowed out and replaced by slop, but what really hurts is that the slop is being produced by bots trained on precisely that amateur content.

A Plan for Improving JavaScript's Trustworthiness on the Web

Hën, 20/10/2025 - 2:20pd
On Cloudflare's blog, a senior research engineer shares a plan for "improving the trustworthiness of JavaScript on the web." "It is as true today as it was in 2011 that Javascript cryptography is Considered Harmful." The main problem is code distribution. Consider an end-to-end-encrypted messaging web application. The application generates cryptographic keys in the client's browser that lets users view and send end-to-end encrypted messages to each other. If the application is compromised, what would stop the malicious actor from simply modifying their Javascript to exfiltrate messages? It is interesting to note that smartphone apps don't have this issue. This is because app stores do a lot of heavy lifting to provide security for the app ecosystem. Specifically, they provide integrity, ensuring that apps being delivered are not tampered with, consistency, ensuring all users get the same app, and transparency, ensuring that the record of versions of an app is truthful and publicly visible. It would be nice if we could get these properties for our end-to-end encrypted web application, and the web as a whole, without requiring a single central authority like an app store. Further, such a system would benefit all in-browser uses of cryptography, not just end-to-end-encrypted apps. For example, many web-based confidential LLMs, cryptocurrency wallets, and voting systems use in-browser Javascript cryptography for the last step of their verification chains. In this post, we will provide an early look at such a system, called Web Application Integrity, Consistency, and Transparency (WAICT) that we have helped author. WAICT is a W3C-backed effort among browser vendors, cloud providers, and encrypted communication developers to bring stronger security guarantees to the entire web... We hope to build even wider consensus on the solution design in the near future.... We would like to have a way of enforcing integrity on an entire site, i.e., every asset under a domain. For this, WAICT defines an integrity manifest, a configuration file that websites can provide to clients. One important item in the manifest is the asset hashes dictionary, mapping a hash belonging to an asset that the browser might load from that domain, to the path of that asset. The blog post points out that the WEBCAT protocol (created by the Freedom of Press Foundation) "allows site owners to announce the identities of the developers that have signed the site's integrity manifest, i.e., have signed all the code and other assets that the site is serving to the user... We've made WAICT extensible enough to fit WEBCAT inside and benefit from the transparency components." The proposal also envisions a service storing metadata for transparency-enabled sites on the web (along with "witnesses" who verify the prefix tree holding the hashes for domain manifests). "We are still very early in the standardization process," with hopes to soon "begin standardizing the integrity manifest format. And then after that we can start standardizing all the other features. We intend to work on this specification hand-in-hand with browsers and the IETF, and we hope to have some exciting betas soon. In the meantime, you can follow along with our transparency specification draft,/A>, check out the open problems, and share your ideas."

Should Workers Start Learning to Work With AI?

Hën, 20/10/2025 - 1:20pd
"My boss thinks AI will solve every problem and is wildly enthusiastic about it," complains a mid-level worker at a Fortune 500 company, who considers the technology "unproven and wildly erratic." So how should they navigate the next 10 years until retirement, they ask the Washington Post's "Work Advice" columnist. The columnist first notes that "Despite promises that AI will eliminate tedious, 'low-value' tasks from our workload, many consumers and companies seem to be using it primarily as a cheap shortcut to avoid hiring professional actors, writers or artists — whose work, in some cases, was stolen to train the tools usurping them..." Kevin Cantera, a reader from Las Cruces, New Mexico [a writer for an education-tech compay], willingly embraced AI for work. But as it turns out, he was training his replacement... Even without the "AI will take our jobs" specter, there's much to be wary of in the AI hype. Faster isn't always better. Parroting and predicting linguistic patterns isn't the same as creativity and innovation... There are concerns about hallucinations, faulty data models, and intentional misuse for purposes of deception. And that's not even addressing the environmental impact of all the power- and water-hogging data centers needed to support this innovation. And yet, it seems, resistance may be futile. The AI genie is out of the bottle and granting wishes. And at the rate it's evolving, you won't have 10 years to weigh the merits and get comfortable with it. Even if you move on to another workplace, odds are AI will show up there before long. Speaking as one grumpy old Luddite to another, it might be time to get a little curious about this technology just so you can separate helpfulness from hype. It might help to think of AI as just another software tool that you have to get familiar with to do your job. Learn what it's good for — and what it's bad at — so you can recommend guidelines for ethical and beneficial use. Learn how to word your wishes to get accurate results. Become the "human in the loop" managing the virtual intern. You can test the bathwater without drinking it. Focus on the little ways AI can accommodate and support you and your colleagues. Maybe it could handle small tasks in your workflow that you wish you could hand off to an assistant. Automated transcriptions and meeting notes could be a life-changer for a colleague with auditory processing issues. I can't guarantee that dabbling in AI will protect your job. But refusing to engage definitely won't help. And if you decide it's time to change jobs, having some extra AI knowledge and experience under your belt will make you a more attractive candidate, even if you never end up having to use it.

Researchers Build Complex 3D-Printed, Carbon-Absorbing Bridge Inspired by Bones

Sht, 18/10/2025 - 7:34md
Concrete accounts for about 8% of the world's greenhouse gas emissions, notes CNN. But a research team at the University of Pennsylvania just used a robotic 3D printer to construct a bridge with "complex, lattice-like patterns" that are just as strong and durable — but with materials that absorb more carbon dioxide. Check out the photos of the "Diamanti" projects "post-tensioned concrete canopy". And CNN's report includes an animated photo showing the 3D printer in action: While most regular concrete absorbs carbon dioxide (up to 30% of its production emissions over its entire life cycle, according to some research), Diamanti's enhanced concrete mixture absorbs 142% more carbon dioxide than conventional concrete mixes. Its first design, a pedestrian bridge, uses 60% less material while retaining mechanical strength, says Masoud Akbarzadeh, an associate professor of architecture at the University of Pennsylvania and director of the lab that spearheaded the project. "Through millions of years of evolution, nature has learned that you don't need material everywhere," says Akbarzadeh. "If you take a cross section of a bone, you realize that bone is quite porous, but there are certain patterns within which the load (or weight) is transferred." By mimicking the structures in certain porous bones — known as triply periodic minimal surface (TPMS) structures — âDiamanti also increased the surface area of the bridge, increasing the concrete mixture's carbon absorption potential by another 30%... According to Akbarzadeh, 3D printing reduces construction time, material, and energy use by 25%, and its structural system reduces the need for steel by 80%, minimizing use of another emissions-heavy material. He added that using the technique with Diamanti's concrete significantly cuts greenhouse gas emissions compared to regular construction techniques, and reduces construction costs by 25% to 30%. "Even without the material innovation, the higher surface itself allows higher CO2 absorption," one engineering lecturer tells CNN. The project was a collaboration with chemical company Sika, funded with grants from the U.S. Energy Department, and is now preparing its first full-size prototype in France. The team has published their findings in the journal Advanced Functional Materials earlier this year.

'How We Sharpened the James Webb Telescope's Vision From a Million Kilometers Away'

Sht, 18/10/2025 - 6:34md
The James Webb Space Telescope gets its highest resolution with the aperture masking interferometer (or AMI), "a tiny piece of precisely machined metal that slots into one of the telescope's cameras," according to a new article by Benjamin Pope, an associated math professor at Macquarie University. "We can finally present its first successful observations of stars, planets, moons and even black hole jets." [AMI] was put on Webb to diagnose and measure any blur in its images. Even nanometres of distortion in Webb's 18 hexagonal primary mirrors and many internal surfaces will blur the images enough to hinder the study of planets or black holes, where sensitivity and resolution are key. AMI filters the light with a carefully structured pattern of holes in a simple metal plate, to make it much easier to tell if there are any optical misalignments. We wanted to use this mode to observe the birth places of planets, as well as material being sucked into black holes. But before any of this, AMI showed Webb wasn't working entirely as hoped. At very fine resolution — at the level of individual pixels — all the images were slightly blurry due to an electronic effect: brighter pixels leaking into their darker neighbours. This is not a mistake or flaw, but a fundamental feature of infrared cameras that turned out to be unexpectedly serious for Webb. This was a dealbreaker for seeing distant planets many thousands of times fainter than their stars a few pixels away: my colleagues quickly showed that its limits were more than ten times worse than hoped. So, we set out to correct it... We built a computer model to simulate AMI's optical physics, with flexibility about the shapes of the mirrors and apertures and about the colours of the stars. We connected this to a machine learning model to represent the electronics with an "effective detector model" — where we only care about how well it can reproduce the data, not about why. After training and validation on some test stars, this setup allowed us to calculate and undo the blur in other data, restoring AMI to full function. It doesn't change what Webb does in space, but rather corrects the data during processing. It worked beautifully — the star HD 206893 hosts a faint planet and the reddest-known brown dwarf (an object between a star and a planet). They were known but out of reach with Webb before applying this correction. Now, both little dots popped out clearly in our new maps of the system... With the new correction, we brought Jupiter's moon Io into focus, clearly tracking its volcanoes as it rotates over an hour-long timelapse. "This correction has opened the door to using AMI to prospect for unknown planets at previously impossible resolutions and sensitivities..." the article points out. "Our results on painstakingly testing and enhancing AMI are now released on the open-access archive arXiv in a pair of papers." Thanks to long-time Slashdot reader schwit1 for sharing the article.

Are Parts of the World Retreating on Electric Vehicles?

Sht, 18/10/2025 - 5:34md
Canada's Prime Minister "paused an electric-vehicle sales mandate that was set to take effect next year," reports the Wall Street Journal, which argues a kind of retreat from electric-vehicle ambitions "is spreading around the globe." Even the U.K.'s Prime Minister "has allowed for a more flexible timetable to hit the country's EV targets." And demand is expected to drop in the U.S., where global consulting firm AlixPartners now predicts EVs will make up 18% of new-vehicle sales by 2030 — just half of what they'd predicted two years ago: j U.S. automaker GM will take a $1.6 billion charge "because of sinking EV sales," reports the Wall Street Journal, "a shift it blamed on recent moves by the U.S. government to end EV subsidies and regulatory mandates... That might just be the beginning of a financial reckoning from automakers that poured billions into new electric models — from sports cars and sedans to big pickups and sport-utility vehicles — to try to get ready for the government-backed EV mandates. Automakers have been saying that consumers aren't adopting EVs as quickly as expected, and government efforts to proliferate the technology are hammering their bottom lines. GM, in announcing its charge, said it is reassessing EV capacity and warned that more losses are possible...Carmakers argue the EV business model is an unprofitable proposition given still-high battery costs, spotty car-charging networks and dwindling government subsidies. Incentive programs have ended or have been pared back across Europe and in the U.S. and Canada. Volkswagen, burdened with massive electrification costs, helped spur the reckoning in Europe when it said it would cut 35,000 jobs as part of a deal with its union. The move sent shock waves through the region's political establishment. Weeks later, the EU launched a "strategic dialogue" with the automotive industry that led to a more flexible timetable for automakers to meet its emissions rules for 2025.

Reddit Mod Warns 'Do Not Trust' AI-Powered 'Reddit Answers' After It Posts Dangerous Health Advice

Sht, 18/10/2025 - 4:34md
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."

Email Bombs Exploit Lax Authentication In Zendesk

Sht, 18/10/2025 - 3:00md
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."
