10 janvier 2026 à 00:45
Microsoft is testing a new Windows policy that lets IT administrators uninstall Microsoft Copilot from managed devices. The change rolls out via Windows Insider builds and works through standard management tools like Intune and SCCM. BleepingComputer reports: The new policy will apply to devices where the Microsoft 365 Copilot and Microsoft Copilot are both installed, the Microsoft Copilot app was not installed by the user, and the Microsoft Copilot app was not launched in the last 28 days. "Admins can now uninstall Microsoft Copilot for a user in a targeted way by enabling a new policy titled RemoveMicrosoftCopilotApp," the Windows Insider team said. "If this policy is enabled, the Microsoft Copilot app will be uninstalled, once. Users can still re-install if they choose to. This policy is available on Enterprise, Pro, and EDU SKUs. To enable this policy, open the Group policy editor and go to: User Configuration -> Administrative Templates -> Windows AI -> Remove Microsoft Copilot App."

Google: Don't Make 'Bite-Sized' Content For LLMs If You Care About Search Rank

An anonymous reader quotes a report from Ars Technica: Search engine optimization, or SEO, is a big business. While some SEO practices are useful, much of the day-to-day SEO wisdom you see online amounts to superstition. An increasingly popular approach geared toward LLMs called "content chunking" may fall into that category. In the latest installment of Google's Search Off the Record podcast, John Mueller and Danny Sullivan say that breaking content down into bite-sized chunks for LLMs like Gemini is a bad idea. You've probably seen websites engaging in content chunking and scratched your head, and for good reason -- this content isn't made for you. The idea is that if you split information into smaller paragraphs and sections, it is more likely to be ingested and cited by gen AI bots like Gemini. So you end up with short paragraphs, sometimes with just one or two sentences, and lots of subheads formatted like questions one might ask a chatbot. According to Google's Danny Sullivan, this is a misconception, and Google doesn't use such signals to improve ranking. "One of the things I keep seeing over and over in some of the advice and guidance and people are trying to figure out what do we do with the LLMs or whatever, is that turn your content into bite-sized chunks, because LLMs like things that are really bite size, right?" said Sullivan. "So... we don't want you to do that." The conversation, which begins around the podcast's 18-minute mark, goes on to illustrate the folly of jumping on the latest SEO trend. Sullivan notes that he has consulted engineers at Google before making this proclamation. Apparently, the best way to rank on Google continues to be creating content for humans rather than machines. That ensures long-term search exposure, because the behavior of human beings -- what they choose to click on -- is an important signal for Google.

Longtime Slashdot reader chicksdaddy writes: CES, the Consumer Electronics Show, isn't just about shiny new gadgets. As AP reports, this year brought back the fifth annual Worst in Show anti-awards, calling out the most harmful, wasteful, invasive, and unfixable tech at the Las Vegas show. The coalition behind the awards -- including Repair.org, iFixit, EFF, PIRG, Secure Repairs, and others -- put the spotlight on products that miss the point of innovation and make life worse for users. 2026 Worst in Show winners include: Overall (and Repairability): Samsung's AI-packed Family Hub Fridge -- over-engineered, hard to fix, and trying to do everything but keep food cold. Privacy: Amazon Ring AI -- expanding surveillance with features like facial recognition and mobile towers. Security: Merach UltraTread treadmill -- an AI fitness coach that also hoovers up sensitive data with weak security guarantees, including a privacy policy that declares the company "cannot guarantee the security of your personal information" (!!). Environmental Impact: Lollipop Star -- a single-use, music-playing electronic lollipop that epitomizes needless e-waste. Enshittification: Bosch eBike Flow App -- pushing lock-in and digital restrictions that make gear worse over time. "Who Asked For This?": Bosch Personal AI Barista -- a voice-assistant coffee maker that nobody really wanted. People's Choice: Lepro Ami AI Companion -- an overhyped "soulmate" cam that creeps more than it comforts. The message? Not all tech is progress. Some products add needless complexity, threaten privacy, or throw sustainability out the window -- and the industry's watchdogs are calling them out.

Italy Fines Cloudflare 14 Million Euros For Refusing To Filter Pirate Sites On Public 1.1.1.1 DNS

Par :BeauHD
9 janvier 2026 à 22:02
An anonymous reader quotes a report from TorrentFreak: Italy's communications regulator AGCOM imposed a record-breaking 14.2 million-euro fine on Cloudflare after the company failed to implement the required piracy blocking measures. Cloudflare argued that filtering its global 1.1.1.1 DNS resolver would be "impossible" without hurting overall performance. AGCOM disagreed, noting that Cloudflare is not necessarily a neutral intermediary either. [...] "The measure, in addition to being one of the first financial penalties imposed in the copyright sector, is particularly significant given the role played by Cloudflare" AGCOM notes, adding that Cloudflare is linked to roughly 70% of the pirate sites targeted under its regime. In its detailed analysis, the regulator further highlighted that Cloudflare's cooperation is "essential" for the enforcement of Italian anti-piracy laws, as its services allow pirate sites to evade standard blocking measures. Cloudflare has strongly contested the accusations throughout AGCOM's proceedings and previously criticized the Piracy Shield system for lacking transparency and due process. While the company did not immediately respond to our request for comment, it will almost certainly appeal the fine. This appeal may also draw the interest of other public DNS resolvers, such as Google and OpenDNS. AGCOM, meanwhile, says that it remains fully committed to enforcing the local piracy law. The regulator notes that since the Piracy Shield started in February 2024, 65,000 domain names and 14,000 IP addresses were blocked.

Fusion Physicists Found a Way Around a Long-Standing Density Limit

Par :BeauHD
9 janvier 2026 à 10:00
alternative_right shares a report from ScienceAlert: At the Experimental Advanced Superconducting Tokamak (EAST), physicists successfully exceeded what is known as the Greenwald limit, a practical density boundary beyond which plasmas tend to violently destabilize, often damaging reactor components. For a long time, the Greenwald limit was accepted as a given and incorporated into fusion reactor engineering. The new work shows that precise control over how the plasma is created and interacts with the reactor walls can push it beyond this limit into what physicists call a 'density-free' regime. [...] A team led by physicists Ping Zhu of Huazhong University of Science and Technology and Ning Yan of the Chinese Academy of Sciences designed an experiment to take this theory further, based on a simple premise: that the density limit is strongly influenced by the initial plasma-wall interactions as the reactor starts up. In their experiment, the researchers wanted to see if they could deliberately steer the outcome of this interaction. They carefully controlled the pressure of the fuel gas during tokamak startup and added a burst of heating called electron cyclotron resonance heating. These changes altered how the plasma interacts with the tokamak walls through a cooler plasma boundary, which dramatically reduced the degree to which wall impurities entered the plasma. Under this regime, the researchers were able to reach densities up to about 65 percent higher than the tokamak's Greenwald limit. This doesn't mean that magnetically confined plasmas can now operate with no density limits whatsoever. However, it does show that the Greenwald limit is not a fundamental barrier and that tweaking operational processes could lead to more effective fusion reactors. The findings have been published in Science Advances.

Ultimate Camouflage Tech Mimics Octopus In Scientific First

9 janvier 2026 à 07:00
Researchers at Stanford University have created a programmable synthetic "skin" that can independently change color and texture, "a feat previously only available within the animal kingdom," reports the Register. From the report: The technique employs electron beams to write patterns and add optical layers that create color effects. When exposed to water, the film swells to reveal texture and colors independently, depending on which side of the material is exposed, according to a paper published in the scientific journal Nature this week. In an accompanying article, University of Stuttgart's Benjamin Renz and Na Liu said the researchers' "most striking achievement was a photonic skin in which color and texture could be independently controlled, mirroring the separate regulation... in octopuses." The research team used the polymer PEDOT:PSS, which can swell in water, as the basis for their material. Its reaction to water can be controlled by irradiating it with electrons, creating textures and patterns in the film. By adding thin layers of gold, the researchers turned surface texture into tunable optical effects. A single layer could be used to scatter light, giving the shiny metal a matte, textured appearance. To control color, a polymer film was sandwiched between two layers of gold, forming an optical cavity, which selectively reflects light.

Some Super-Smart Dogs Can Learn New Words Just By Eavesdropping

Par :BeauHD
9 janvier 2026 à 03:30
An anonymous reader quotes a report from NPR: [I]t turns out that some genius dogs can learn a brand new word, like the name of an unfamiliar toy, by just overhearing brief interactions between two people. What's more, these "gifted" dogs can learn the name of a new toy even if they first hear this word when the toy is out of sight -- as long as their favorite human is looking at the spot where the toy is hidden. That's according to a new study in the journal Science. "What we found in this study is that the dogs are using social communication. They're using these social cues to understand what the owners are talking about," says cognitive scientist Shany Dror of Eotvos Lorand University and the University of Veterinary Medicine, Vienna. "This tells us that the ability to use social information is actually something that humans probably had before they had language," she says, "and language was kind of hitchhiking on these social abilities." [...] "There's only a very small group of dogs that are able to learn this differentiation and then can learn that certain labels refer to specific objects," she says. "It's quite hard to train this and some dogs seem to just be able to do it." [...] To explore the various ways that these dogs are capable of learning new words, Dror and some colleagues conducted a study that involved two people interacting while their dog sat nearby and watched. One person would show the other a brand new toy and talk about it, with the toy's name embedded into sentences, such as "This is your armadillo. It has armadillo ears, little armadillo feet. It has a tail, like an armadillo tail." Even though none of this language was directed at the dogs, it turns out the super-learners registered the new toy's name and were later able to pick it out of a pile, at the owner's request. To do this, the dogs had to go into a separate room where the pile was located, so the humans couldn't give them any hints. Dror says that as she watched the dogs on camera from the other room, she was "honestly surprised" because they seemed to have so much confidence. "Sometimes they just immediately went to the new toy, knowing what they're supposed to do," she says. "Their performance was really, really high." She and her colleagues wondered if what mattered was the dog being able to see the toy while its name was said aloud, even if the words weren't explicitly directed at the dog. So they did another experiment that created a delay between the dog seeing a new toy and hearing its name. The dogs got to see the unfamiliar toy and then the owner dropped the toy in a bucket, so it was out of sight. Then the owner would talk to the dog, and mention the toy's name, while glancing down at the bucket. While this was more difficult for dogs, overall they still could use this information to learn the name of the toy and later retrieve it when asked. "This shows us how flexible they are able to learn," says Dror. "They can use different mechanisms and learn under different conditions."

YouTube Will Now Let You Filter Shorts Out of Search Results

YouTube is updating search filters so users can explicitly choose between Shorts and long-form videos. The change also replaces view-count sorting with a new "Popularity" filter and removes underperforming options like "Sort by Rating." The Verge reports: Right now, a filter-less search shows a mix of longform and short form videos, which can be annoying if you just want to see videos in one format or the other. But in the new search filters, among other options, you can pick to see "Videos," which in my testing has only showed a list of longform videos, or "Shorts," which just shows Shorts. YouTube is also removing the "Upload Date - Last Hour" and "Sort by Rating" filters because they "were not working as expected and had contributed to user complaints." The company will still offer other "Upload Date" filters, like "Today," "This week," "This Month," and "This Year," and you can also find popular videos with the new "Popularity" filter, which is replacing the "View count" sort option. (With the new "Popularity" filter, YouTube says that "our systems assess a video's view count and other relevance signals, such as watch time, to determine its popularity for that specific query.")

Lawsuit Over OpenAI For-Profit Conversion Can Head To Trial, US Judge Says

Longtime Slashdot reader schwit1 shares a report from Reuters: Billionaire entrepreneur Elon Musk persuaded a judge on Wednesday to allow a jury trial on his allegations that ChatGPT maker OpenAI violated its founding mission in its high-profile restructuring to a for-profit entity. Musk was a cofounder of OpenAI in 2015 but left in 2018 and now runs an AI company that competes with it. U.S. District Judge Yvonne Gonzalez Rogers in Oakland, California, said at a hearing that there was "plenty of evidence" suggesting OpenAI's leaders made assurances that its original nonprofit structure was going to be maintained. The judge said there were enough disputed facts to let a jury consider the claims at a trial scheduled for March, rather than decide the issues herself. She said she would issue a written order after the hearing that addresses OpenAI's bid to throw out the case. [...] Musk contends he contributed about $38 million, roughly 60% of OpenAI's early funding, along with strategic guidance and credibility, based on assurances that the organization would remain a nonprofit dedicated to the public benefit. The lawsuit accuses OpenAI co-founders Sam Altman and Greg Brockman of plotting a for-profit switch to enrich themselves, culminating in multibillion-dollar deals with Microsoft and a recent restructuring. OpenAI, Altman and Brockman have denied the claims, and they called Musk "a frustrated commercial competitor seeking to slow down a mission-driven market leader." Microsoft is also a defendant and has urged the judge to toss Musk's lawsuit. A lawyer for Microsoft said there was no evidence that the company "aided and abetted" OpenAI. OpenAI in a statement after the hearing said: "Mr Musk's lawsuit continues to be baseless and a part of his ongoing pattern of harassment, and we look forward to demonstrating this at trial."

Google Is Adding an 'AI Inbox' To Gmail That Summarizes Emails

An anonymous reader quotes a report from Wired: Google is putting even more generative AI tools into Gmail as part of its goal to further personalize user inboxes and streamline searches. On Thursday, the company announced a new "AI Inbox" tab, currently in a beta testing phase, that reads every message in a user's Gmail and suggests a list of to-dos and key topics, based on what it summarizes. In Google's example of what this AI Inbox could look like in Gmail, the new tab takes context from a user's messages and suggests they reschedule their dentist appointment, reply to a request from their child's sports coach, and pay an upcoming fee before the deadline. Also under the AI Inbox tab is a list of important topics worth browsing, nestled beneath the action items at the top. Each suggested to-do and topic links back to the original email for more context and for verification. [...] For users who are concerned about their privacy, the information Google gleans by skimming through inboxes will not be used to improve the company's foundational AI models. "We didn't just bolt AI onto Gmail," says Blake Barnes, who leads the project for Google. "We built a secure privacy architecture, specifically for this moment." He emphasizes that users can turn off Gmail's new AI tools if they don't want them. At the same time Google announced its AI Inbox, the company made free for all Gmail users multiple Gemini features that were previously available only to paying subscribers. This includes the Help Me Write tool, which generates emails from a user prompt, as well as AI Overviews for email threads, which essentially posts a TL;DR summary at the top of long message threads. Subscribers to Google's Ultra and Pro plans, which start at $20 a month, get two additional new features in their Gmail inbox. First, an AI proofreading tool that suggests more polished grammar and sentence structures. And second, an AI Overviews tool that can search your whole inbox and create relevant summaries on a topic, rather than just summarizing a single email thread.

French Court Orders Google DNS to Block Pirate Sites, Dismisses 'Cloudflare-First' Defense

Par :BeauHD
8 janvier 2026 à 23:30
Paris Judicial Court ordered Google to block additional pirate sports-streaming domains at the DNS level, rejecting Google's argument that enforcement should target upstream providers like Cloudflare first. "The blockade was requested by Canal+ and aims to stop pirate streams of Champions League games," notes TorrentFreak. From the report: Most recently, Google was compelled to take action following a complaint from French broadcaster Canal+ and its subsidiaries regarding Champions League piracy.. Like previous blocking cases, the request is grounded in Article L. 333-10 of the French Sports Code, which enables rightsholders to seek court orders against any entity that can help to stop 'serious and repeated' sports piracy. After reviewing the evidence and hearing arguments from both sides, the Paris Court granted the blocking request, ordering Google to block nineteen domain names, including antenashop.site, daddylive3.com, livetv860.me, streamysport.org and vavoo.to. The latest blocking order covers the entire 2025/2026 Champions League series, which ends on May 30, 2026. It's a dynamic order too, which means that if these sites switch to new domains, as verified by ARCOM, these have to be blocked as well. Google objected to the blocking request. Among other things, it argued that several domains were linked to Cloudflare's CDN. Therefore, suspending the sites on the CDN level would be more effective, as that would render them inaccessible. Based on the subsidiarity principle, Google argued that blocking measures should only be ordered if attempts to block the pirate sites through more direct means have failed. The court dismissed these arguments, noting that intermediaries cannot dictate the enforcement strategy or blocking order. Intermediaries cannot require "prior steps" against other technical intermediaries, especially given the "irremediable" character of live sports piracy. The judge found the block proportional because Google remains free to choose the technical method, even if the result is mandated. Internet providers, search engines, CDNs, and DNS resolvers can all be required to block, irrespective of what other measures were taken previously. Google further argued that the blocking measures were disproportionate because they were complex, costly, easily bypassed, and had effects beyond the borders of France. The Paris court rejected these claims. It argued that Google failed to demonstrate that implementing these blocking measures would result in "important costs" or technical impossibilities. Additionally, the court recognized that there would still be options for people to bypass these blocking measures. However, the blocks are a necessary step to "completely cease" the infringing activities.

Wi-Fi Advocates Get Win From FCC With Vote To Allow Higher-Power Devices

Par :BeauHD
8 janvier 2026 à 22:10
An anonymous reader quotes a report from Ars Technica: The Federal Communications Commission plans to authorize a new category of wireless devices in the 6 GHz Wi-Fi band that will be permitted to operate at higher power levels than currently allowed. The FCC will also consider authorizing higher power levels for certain wireless devices that are only allowed to operate indoors. The FCC said it scheduled a vote for its January 29 meeting on an order "to create a new category of unlicensed devices... that can operate outdoors and at higher power than previously authorized devices." These so-called Geofenced variable power (GVP) devices operating on the 6 GHz band will "support high data rates suitable for AR/VR, short-range hotspots, automation, and indoor navigation," and "overcome limitations of previous device classes by allowing higher power and outdoor mobility," the FCC said. They will be required to work with geofencing systems to avoid interference with fixed microwave links and radio astronomy observatories. FCC Chairman Brendan Carr attributed the FCC's planned action to President Trump in a press release titled, "President Trump Unleashes American Innovation With 6 GHz Win." That's consistent with Carr's relatively new stance that the FCC takes orders from the president, despite his insisting during the Biden era that the FCC must operate independently from the White House. While many of Carr's regulatory decisions have been criticized by consumer advocates, the 6 GHz action is an exception. Michael Calabrese, of New America's Open Technology Institute, told Ars that "increasing the power levels for Wi-Fi connections to peripheral devices such as AR/VR is a big win for consumers" and a change that has been "long advocated by the Wi-Fi community." Carr said that the FCC "will vote on an order that expands unlicensed operations in the 6 GHz band so that consumers can benefit from better, faster Wi-Fi and an entirely new generation of wireless devices -- from AR/VR and IoT to a range of innovative smart devices. [It] will do so through a set of forward-looking regulations that allow devices to operate at higher power while protecting incumbent users, including through geofencing systems." [...] A draft of the order said the planned "additional power will enable composite standard-power/LPI access points to increase indoor coverage and provide more versatility to American consumers." The FCC will also seek comment on a proposal to authorize LPI access points on cruise ships.

SteamOS Continues Its Slow Spread Across the PC Gaming Landscape

An anonymous reader quotes a report from Ars Technica: SteamOS's slow march across the Windows-dominated PC gaming landscape is continuing to creep along. At CES this week, Lenovo announced it will launch a version of last year's high-priced, high-powered Legion Go 2 handheld with Valve's gaming-focused, Linux-based OS pre-installed starting in June. And there are some intriguing signs from Valve that SteamOS could come to non-AMD devices in the not-too-distant future as well. [...] Valve has also been working behind the scenes to expand SteamOS's footprint beyond its own hardware. After rolling out the SteamOS Compatible software label last May, SteamOS version 3.7 offered support for manual installation on AMD-powered handhelds like the ROG Ally and the original Legion Go. Even as SteamOS slowly spreads across the AMD-powered hardware landscape, the OS continues to be limited by a lack of compatibility with the wide world of Arm devices. That could change in the near future, though, as Valve's upcoming Steam Frame VR headset will sport a new version of SteamOS designed specifically for the headset's Arm-based hardware. [...] It's an especially exciting prospect when you consider the wide range of Arm-based Android gaming handhelds that currently exist across the price and performance spectrum. While emulators like Fex can technically let players access Steam games on those kinds of handhelds, official Arm support for SteamOS could lead to a veritable Cambrian explosion of hardware options with native SteamOS support. [...] That's great news for fans of PC-based gaming handhelds, just as the announcement of Valve's Steam Machine will provide a convenient option for SteamOS access on the living room TV. For desktop PC gamers, though, rigs sporting Nvidia GPUs might remain the final frontier for SteamOS in the foreseeable future. "With Nvidia, the integration of open-source drivers is still quite nascent," [Valve's Pierre-Louis Griffais] told Frandroid about a year ago. "There's still a lot of work to be done on that front So it's a bit complicated to say that we're going to release this version when most people wouldn't have a good experience."

Rubin Observatory Spots an Asteroid That Spins Fast Enough To Set a Record

8 janvier 2026 à 10:00
Astronomers using the Vera C. Rubin Observatory have discovered a record-setting asteroid, known as 2025 MN45, nearly half a mile wide and spinning once every 1.88 minutes -- the fastest known rotation for an object of its size. "This is now the fastest-spinning asteroid that we know of, larger than 500 meters," said Sarah Greenstreet, University of Washington astronomer and lead author of the study. The findings have been published in the The Astrophysical Journal Letters. GeekWire reports: 2025 MN45 is one of more than 2,100 solar system objects that were detected during the observatory's commissioning phase. Over time, the LSST Camera tracked variations in the light reflected by those objects. Greenstreet and her colleagues analyzed those variations to determine the size, distance, composition and rate of rotation for 76 asteroids, all but one of which are in the main asteroid belt between the orbits of Mars and Jupiter. (The other asteroid is a near-Earth object.) The team found 16 "super-fast rotators" spinning at rates ranging between 13 minutes and 2.2 hours per revolution -- plus three "ultra-fast rotators," including 2025 MN45, that make a full revolution in less than five minutes. Greenstreet said 2025 MN45 appears to consist of solid rock, as opposed to the "rubble pile" material that most asteroids are thought to be made of. "We also believe that it's likely a collisionary fragment of a much larger parent body that, early in the solar system's history, was heated enough that the material internal to it melted and differentiated," Greenstreet said. She and her colleagues suggest that the primordial collision blasted 2025 MN45 from the dense core of the parent body and sent it whirling into space.

How Bright Headlights Escaped Regulation

Par :BeauHD
8 janvier 2026 à 07:00
Longtime Slashdot reader schwit1 shares a report from Autoblog: ... the problem is that the federal brightness standards for automotive headlights have not changed for decades. The Federal Motor Vehicle Safety Standard No. 108 hasn't had significant updates since 1986, with an addition allowing Adaptive Driving Beam (ADB) headlights coming only in 2022. The NHTSA last investigated (PDF) the issue of headlamp glare in 2003. The current standards include huge loopholes for auto manufacturers to emit as much light as desired, as long as the manufacturer meets the requirements of the other parts of the regulation. LEDs can be made to focus light using lasers, and auto manufacturers use this ability to their advantage. The regulatory standard prohibits excessive light in certain areas by referencing old technologies, but manufacturers design the areas in question to be shaded so that the total light output can still be increased greatly overall. Manufacturers want as much light as possible in order to get a high score for the IIHS headlight safety ratings. [...] Although the U.S. finally approved the ADB technology in 2022, manufacturers are wary of implementing it because of conflicting regulations, with a few exceptions, such as Rivian. To fix this problem, the first step is to update Standard 108 with a cap on the maximum allowable brightness for LED technology. Next, states should begin requiring headlight alignment inspection during vehicle inspections. Finally, NHTSA should enforce a ban against the sale of aftermarket LEDs that exceed the allowed brightness, at least for on-road use. The Soft Lights Foundation has collected over 77,000 signatures calling for federal action to limit headlight brightness. People are frustrated with being temporarily blinded while driving, and it's high time some regulation was put into place. Vehicles have become cleaner and safer through smart regulation; the same just needs to be done with headlights.

Japan's Nuclear Watchdog Halts Plant's Reactor Safety Screening Over Falsified Data

Par :BeauHD
8 janvier 2026 à 03:30
An anonymous reader quotes a report from the Associated Press: Japan's nuclear watchdog said Wednesday it is scrapping the safety screening for two reactors at the Hamaoka nuclear power plant in central Japan, after its operator was found to have fabricated data about earthquake risks. It was a setback to Japan's attempts to accelerate nuclear reactor restarts. Less than a quarter of commercial nuclear reactors are operational in the wake of the 2011 Fukushima Daiichi meltdowns, but rising energy costs and pressure to reduce carbon emissions have pushed the government to prioritize nuclear power. Chubu Electric Power Co. had applied for safety screening to resume operations at the No. 3 and 4 reactors at the Hamaoka plant in 2014 and 2015. Two other reactors at the plant are being decommissioned, and a fifth is idle. The plant, about 200 kilometers (125 miles) west of Tokyo, is located on a coastal area known for potential risks from so-called Nankai Trough megaquakes. The Nuclear Regulation Authority said it started an internal investigation last February, after receiving a tip from a whistleblower that the utility had for years provided fabricated data that underestimated potential seismic risks. The regulator suspended the screening for the reactors after it confirmed the falsification and the utility acknowledged the fabrication in mid-December, said Shinsuke Yamanaka, the watchdog's chair. The NRA is also considering inspecting the utility headquarters. [...] The scandal surfaced Monday when Chubu Electric President Kingo Hayashi acknowledged that workers at the utility used inappropriate seismic data with an alleged intention to underestimate seismic risks. He apologized and pledged to establish an independent panel for investigation. The screening, including data that had been approved earlier, would have to start from scratch or possibly be rejected entirely, Yamanaka said. The NRA will decide on the case next week, without waiting for the utility's probe results, he said. "Ensuring safety is the first and foremost responsibility for nuclear plant operators," Yamanaka said. "It is outrageous and it's a serious challenge to safety regulation."

AI Chip Frenzy To Wallop DRAM Prices With 70% Hike

Samsung Electronics and SK hynix are projected to raise server memory prices by up to 70% in early 2026, according to Korea Economic Daily. "Combined with 50 percent increases in 2025, this could nearly double prices by mid-2026," reports the Register. From the report: The two Korean giants, alongside US-based Micron, dominate global memory production. All three are reallocating advanced manufacturing capacity to high-margin server DRAM and HBM chips for AI infrastructure, squeezing supply for PCs and smartphones. Financial analysts have raised their earnings forecasts for the firms in response, as they look to benefit from the AI infrastructure boom that is driving up prices for everyone else. Taiwan-based market watcher TrendForce reports that conventional DRAM prices already jumped 55-60 percent in a single quarter. Yet despite the focus on server chips, supply of these components continues to be strained too, with supplier inventories falling and shipment growth reliant on wafer output increases, according to TrendForce. As a result, it forecasts that server DRAM prices will jump by more than 60 percent in the first quarter of 2026. Prior to Christmas, analyst IDC noted the "unprecedented" memory chip shortage and warned this would have knock-on effects for both hardware makers and end users that may persist well into 2027.
