More than a half dozen federal departments and agencies have backed a proposal to ban future sales of the most popular home routers in the United States on the grounds that the vendor's ties to mainland China make them a national security risk, Washington Post reported Thursday, citing people briefed on the matter. From the report: The proposal, which arose from a months-long risk assessment, calls for blocking sales of networking devices from TP-Link Systems of Irvine, California, which was spun off from a China-based company, TP-Link Technologies, but owns some of that company's former assets in China.

The ban was proposed by the Commerce Department and supported this summer by an interagency process that includes the Departments of Homeland Security, Justice and Defense, the people said. "TP-Link vigorously disputes any allegation that its products present national security risks to the United States," Ricca Silverio, a spokeswoman for TP-Link Systems, said in a statement. "TP-Link is a U.S. company committed to supplying high-quality and secure products to the U.S. market and beyond."

If imposed, the ban would be among the largest in consumer history and a possible sign that the East-West divide over tech independence is still deepening amid reports of accelerated Chinese government-supported hacking. Only the legislated ban of Chinese-owned TikTok, which President Donald Trump has averted with executive orders and a pending sale, would impact more U.S. consumers.

Google will offer 18-month free access to its Gemini AI service for all 505 million telecom users of India's Reliance Jio, a tie-up that follows similar freebies from rivals including OpenAI to boost adoption in the world's most populous nation. From a report: The move also comes weeks after Google committed to invest $15 billion in AI infrastructure capacity in India, its biggest investment yet in the critical South Asian market.

[...] The Gemini offer will give Jio users free access to the advanced model of the AI app, two terabytes of cloud storage, and its image and video generation models, in an 18-month offering that is otherwise priced at 35,100 rupees ($399). The companies on Thursday also announced AI partnerships that targeted Indian businesses.

New submitter hadleyburg writes: President Trump has directed the Department of War to restart nuclear weapons testing. The directive appears to be a counter measure to rival nations catching up with the US. The last US nuclear test was an underground test, on September 23, 1992, in Nevada.

Britain is facing mounting pressure to ban mercury dental fillings, one of the few countries yet to prevent the practice, as new data reveals alarming contamination levels in the nation's fish and shellfish. The Guardian: Mercury is a potent neurotoxin that can harm the nervous, digestive and immune systems, as well as the lungs, kidneys, skin and eyes, even at low levels of exposure. Its organic form, methylmercury, is particularly dangerous to unborn babies and can move through the food chain building up in insects, fish and birds.

Britain is lagging behind the rest of the world on phasing out mercury dental fillings, with 43 countries having already banned mercury amalgam, including the EU, Sweden, Norway, Tanzania, Uganda, Indonesia and the Philippines. Northern Ireland will outlaw mercury fillings from 2035 but no such ban is planned in the rest of Britain. According to new analysis by the Rivers Trust and Wildlife and Countryside Link, more than 98% of fish and mussels tested in English rivers and coastal waters contain mercury above safety limits proposed by the EU, with more than half containing more than five times the recommended safe level.

Gallup: After peaking at a record high of 39.9% in 2022, the U.S. adult obesity rate has gradually declined to 37.0% in 2025. This is a statistically meaningful decrease representing an estimated 7.6 million fewer obese adults compared with three years ago. Meanwhile, diagnoses of diabetes -- a lifetime disease that can be managed but not cured -- have now reached an all-time high of 13.8%. Both metrics are part of the ongoing Gallup National Health and Well-Being Index.

[...] Over the past year, more Americans have turned to Type 2 antidiabetic GLP-1 drugs such as semaglutide (brand names Ozempic and Wegovy) for weight loss purposes. The percentage of adults who report taking this class of medicine specifically for weight loss has increased to 12.4%, compared with 5.8% in February 2024 when Gallup first measured it. Usage among women (15.2%) continues to outpace men (9.7%), but both groups have more than doubled their use in the past year. These results dovetail with increased awareness of the drugs used for weight loss, which has risen from 80% to 89% nationally in the same period.

Carmakers in the EU are "days away" from closing production lines, the industry has warned, as a crisis over computer chip supplies from China escalates. From a report: The European Automobile Manufacturers' Association (ACEA) issued an urgent warning on Wednesday saying its members, which include BMW, Fiat, Peugeot and Volkswagen, were now working on "reserve stocks but supplies are dwindling."

"Assembly line stoppages might only be days away. We urge all involved to redouble their efforts to find a diplomatic way out of this critical situation," said its director general, Sigrid de Vries. Another ACEA member, Mercedes, is now searching globally for alternative sources of the crucial semiconductors, according to its chief executive, Ola Kallenius. The chip shortage is also causing problems in Japan, where Nissan's chief performance officer, Guillaume Cartier, told reporters at a car show in Tokyo that the company was only "OK to the first week of November" in terms of supply.

TypeScript overtook Python and JavaScript in August 2025 to become the most used language on GitHub. The shift marked the most significant language change in more than a decade. The language grew by over 1 million contributors in 2025, a 66% increase year over year, and finished August with 2,636,006 monthly contributors.

Nearly every major frontend framework now scaffolds projects in TypeScript by default. Next.js 15, Astro 3, SvelteKit 2, Qwik, SolidStart, Angular 18, and Remix all generate TypeScript codebases when developers create new projects. Type systems reduce ambiguity and catch errors from large language models before production. A 2025 academic study found 94% of LLM-generated compilation errors were type-check failures. Tooling like Vite, ts-node, Bun, and I.D.E. autoconfig hide boilerplate setup. Among new repositories created in the past twelve months, TypeScript accounted for 5,394,256 projects. That represented a 78% increase from the prior year.

An anonymous reader shares a report: The International Criminal Court will switch its internal work environment away from Microsoft Office to Open Desk, a European open source alternative, the institution confirmed to Euractiv. The switch comes amid rising concerns about public bodies being reliant on US tech companies to run their services, which have stepped up sharply since the start of US President Donald Trump's second administration.

For the ICC, such concerns are not abstract: Trump has repeatedly lashed out at the court and slapped sanctions on its chief prosecutor, Karim Khan. Earlier this year, the AP also reported that Microsoft had cancelled Khan's email account, a claim the company denies. "We value our relationship with the ICC as a customer and are convinced that nothing impedes our ability to continue providing services to the ICC in the future," a Microsoft spokesperson told Euractiv.

Meta CEO Mark Zuckerberg is getting ready to dump even more AI-generated posts into your social feeds. From a report: During an earnings call on Wednesday, Zuckerberg said the company will "add yet another huge corpus of content" to its recommendations system as AI "makes it easier to create and remix" work that gets shared online.

"Social media has gone through two eras so far," Zuckerberg said. "First was when all content was from friends, family, and accounts that you followed directly. The second was when we added all of the Creator content." Though Zuckerberg stops short of calling AI the third era of social media, it's clear that the technology will be heavily involved in what comes next.

Zuckerberg said that recommendation systems that "deeply understand" AI-generated posts and "show you the right content" will become "increasingly valuable." The company has already begun embedding AI tools across its apps and is now experimenting with dedicated AI social apps, too.

An anonymous reader quotes a report from Ars Technica: Since launching Google Play (nee Android Market) in 2008, Google has never made a change to the US store that it didn't want to make -- until now. Having lost the antitrust case brought by Epic Games, Google has implemented the first phase of changes mandated by the court. Developers operating in the Play Store will have more freedom to direct app users to resources outside the Google bubble. However, Google has not given up hope of reversing its loss before it's forced to make bigger changes. Epic began pursuing this case in 2020, stemming from its attempt to sell Fortnite content without going through Google's payment system. It filed a similar case against Apple, but the company fell short there because it could not show that Apple put its thumb on the scale. Google, however, engaged in conduct that amounted to suppressing the development of alternative Android app stores. It lost the case and came up short on appeal this past summer, leaving the company with little choice but to prepare for the worst.

Google has updated its support pages to confirm that it's abiding by the court's order. In the US, Play Store developers now have the option of using external payment platforms that bypass the Play Store entirely. This could hypothetically allow developers to offer lower prices, as they don't have to pay Google's commission, which can be up to 30 percent. Devs will also be permitted to direct users to sources for app downloads and payment methods outside the Play Store. Google's support page stresses that these changes are only being instituted in the US version of the Play Store, which is all the US District Court can require. The company also notes that it only plans to adhere to this policy "while the US District Court's order remains in effect." Judge James Donato's order runs for three years, ending on November 1, 2027.

AI "cheating" app Cluely's CEO and cofounder, Chungin "Roy" Lee, said most startups flop because their products don't get seen. From a report: "Engineers just cannot make good content," Lee said during a Wednesday interview at TechCrunch Disrupt 2025 "There's a bunch of shallow replicas, but I challenge you to find one video you think is like, 'Yo, this is as tough as Cluely,'" he told TechCrunch.

Every startup needs to focus more on distribution. And most startups flop because they fail to get seen, even if they have product-market fit, Lee said. Cluely launched earlier this year as a tool to help software engineers cheat on their job interviews, among other use cases. The startup earlier this year posted a tongue-in-cheek video of Lee trying to use Cluely to impress a woman on a date, which went viral.

A critical security flaw in Chromium's Blink rendering engine can crash billions of browsers within seconds. Security researcher Jose Pino discovered the vulnerability and created a proof-of-concept exploit called Brash to demonstrate the bug affecting Chrome, Edge, OpenAI's ChatGPT Atlas, Brave, Vivaldi, Arc, Dia, Opera and Perplexity Comet.

The flaw, reports The Register, exploits the absence of rate limiting on document.title API updates in Chromium versions 143.0.7483.0 and later. The attack injects millions of DOM mutations per second and saturates the main thread. When The Register tested the code on Edge, the browser crashed and the Windows machine locked up after about 30 seconds while consuming 18GB of RAM in one tab. Pino disclosed the bug to the Chromium security team on August 28 and followed up on August 30 but received no response. Google said it is looking into the issue.

OpenAI is reportedly preparing for a massive IPO that could value the company at up to $1 trillion. It follows a recent corporate restructuring that loosened its dependence on Microsoft and aligned its nonprofit foundation with financial success. Reuters reports: OpenAI is considering filing with securities regulators as soon as the second half of 2026, some of the people said. In preliminary discussions, the company has looked at raising $60 billion at the low end and likely more, the people said. They cautioned that talks are early and plans -- including the figures and timing - could change depending on business growth and market conditions. Chief Financial Officer Sarah Friar has told some associates the company is aiming for a 2027 listing, the people said. But some advisers predict it could come even sooner, around late 2026.

[...] An IPO would open the door to more efficient capital raising and enable larger acquisitions using public stock, helping to finance CEO Sam Altman's plans to pour trillions of dollars into AI infrastructure, according to people familiar with the company's thinking. With an annualized revenue run rate expected to reach about $20 billion by year-end, losses are also mounting inside the $500 billion company, the people said. During a livestream on Tuesday, Altman addressed the possibility of going public. "I think it's fair to say it is the most likely path for us, given the capital needs that we'll have," he said.

Universal Music Group has settled its copyright lawsuit with AI music startup Udio and struck a licensing deal to launch a new AI-powered music platform next year. The Verge reports: The deal includes some form of compensation and "will provide further revenue opportunities for UMG artists and songwriters," Universal says. Udio, the company behind "BBL Drizzy," will launch the platform as a subscription service next year. Universal, alongside other industry giants Sony and Warner, sued Udio and another startup Suno for "en masse" copyright infringement last year.

Universal -- whose roster includes some of the world's biggest performers like Taylor Swift, Bad Bunny, and Ariana Grande -- says the new tool will "transform the user engagement experience" and let creators customize, stream, and share music. There's no indication of how much it will cost yet. Udio's existing music maker, which lets you create new songs with a few words, will remain available during the transition, though content will be held "within a walled garden" and security measures like fingerprinting will be added.

An anonymous reader quotes a report from the Guardian: When Google and Amazon negotiated a major $1.2 billion cloud-computing deal in 2021, their customer -- the Israeli government -- had an unusual demand: agree to use a secret code as part of an arrangement that would become known as the "winking mechanism." The demand, which would require Google and Amazon to effectively sidestep legal obligations in countries around the world, was born out of Israel's concerns that data it moves into the global corporations' cloud platforms could end up in the hands of foreign law enforcement authorities.

Like other big tech companies, Google and Amazon's cloud businesses routinely comply with requests from police, prosecutors and security services to hand over customer data to assist investigations. This process is often cloaked in secrecy. The companies are frequently gagged from alerting the affected customer their information has been turned over. This is either because the law enforcement agency has the power to demand this or a court has ordered them to stay silent. For Israel, losing control of its data to authorities overseas was a significant concern. So to deal with the threat, officials created a secret warning system: the companies must send signals hidden in payments to the Israeli government, tipping it off when it has disclosed Israeli data to foreign courts or investigators.

To clinch the lucrative contract, Google and Amazon agreed to the so-called winking mechanism, according to leaked documents seen by the Guardian, as part of a joint investigation with Israeli-Palestinian publication +972 Magazine and Hebrew-language outlet Local Call. Based on the documents and descriptions of the contract by Israeli officials, the investigation reveals how the companies bowed to a series of stringent and unorthodox "controls" contained within the 2021 deal, known as Project Nimbus. Both Google and Amazon's cloud businesses have denied evading any legal obligations.

PC Mag's Michael Kan writes: A "Keep Android Open" campaign is pushing back on new rules from Google that will reportedly block users from sideloading apps on Android phones. It's unclear who's running the campaign, but a blog post on the free Android app store F-Droid is directing users to visit the campaign's website, which urges the public to lobby government regulators to intervene and stop the upcoming restrictions. "Developers should have the right to create and distribute software without submitting to unnecessary corporate surveillance," reads an open letter posted to the site. [...]

Google has described the upcoming change as akin to requiring app developers to go through "an ID check at the airport." However, F-Droid condemned the new requirement as anti-consumer choice. "If you own a computer, you should have the right to run whatever programs you want on it," it says. Additionally, the rules threaten third-party app distribution on F-Droid, which operates as a "free/open-source app distribution" model.

In its blog post, F-Droid warns about the impact on users and Android app developers. "You, the creator, can no longer develop an app and share it directly with your friends, family, and community without first seeking Google's approval," the app store says. "Over half of all humankind uses an Android smartphone," the blog post adds. "Google does not own your phone. You own your phone. You have the right to decide who to trust, and where you can get your software from."

Google and Magic Leap have extended their partnership for another three years to develop Android XR glasses. They also showed off a new prototype concept that combines Google's Raxium microLED light engine with Magic Leap's AR optics, resulting in a lightweight, stylish pair of glasses that blends real-world vision with multimodal AI. 9to5Google reports: As noted by Android Central, a press release shared by Magic Leap adds some further technical details. This includes mentioning that Google's "Raxium microLED light engine" integrates with Magic Leap's tech to bring "digital content seamlessly into the world." As pictured above, the "display" portion of the lens is visible at some angles, but it's largely impossible to see.

Magic Leap and Google will show an AI glasses prototype at FII that will serve as a prototype and reference design for the Android XR ecosystem. The demo shows how Magic Leap's technology, integrated with Google's Raxium microLED light engine, brings digital content seamlessly into the world. The prototypes worn on stage illustrate how comfortable, stylish smart eyewear is possible and the video showed the potential for users to stay present in the real world while tapping into the knowledge and functionality of multimodal AI.

During the presentation, text on the nearby screens suggests that Magic Leap is mainly working with Google on the technology here, rather than bringing its own glasses to market. Magic Leap further hints at this in its press release, calling itself "an AR ecosystem partner" focused on "supporting global technology leaders that want to enter the AR market and accelerate the production of AR glasses."

alternative_right shares a report from Phys.org: Today's cutting-edge theory -- quantum gravity -- suggests that even space and time aren't fundamental. They emerge from something deeper: pure information. This information exists in what physicists call a Platonic realm -- a mathematical foundation more real than the physical universe we experience. It's from this realm that space and time themselves emerge. "The fundamental laws of physics cannot be contained within space and time, because they generate them. It has long been hoped, however, that a truly fundamental theory of everything could eventually describe all physical phenomena through computations grounded in these laws. Yet we have demonstrated that this is not possible. A complete and consistent description of reality requires something deeper -- a form of understanding known as non-algorithmic understanding." "We have demonstrated that it is impossible to describe all aspects of physical reality using a computational theory of quantum gravity," says Dr. Faizal. "Therefore, no physically complete and consistent theory of everything can be derived from computation alone. Rather, it requires a non-algorithmic understanding, which is more fundamental than the computational laws of quantum gravity and therefore more fundamental than spacetime itself."

"Drawing on mathematical theorems related to incompleteness and indefinability, we demonstrate that a fully consistent and complete description of reality cannot be achieved through computation alone," explains Dr. Mir Faizal, Adjunct Professor with UBC Okanagan's Irving K. Barber Faculty of Science. "It requires non-algorithmic understanding, which by definition is beyond algorithmic computation and therefore cannot be simulated. Hence, this universe cannot be a simulation."

The findings have been published in the Journal of Holography Applications in Physics.

An anonymous reader quotes a report from 404 Media: Someone recently managed to get on a Microsoft Teams call with representatives from phone hacking company Cellebrite, and then leaked a screenshot of the company's capabilities against many Google Pixel phones, according to a forum post about the leak and 404 Media's review of the material. The leak follows others obtained and verified by 404 Media over the last 18 months. Those leaks impacted both Cellebrite and its competitor Grayshift, now owned by Magnet Forensics. Both companies constantly hunt for techniques to unlock phones law enforcement have physical access to.

"You can Teams meeting with them. They tell everything. Still cannot extract esim on Pixel. Ask anything," a user called rogueFed wrote on the GrapheneOS forum on Wednesday, speaking about what they learned about Cellebrite capabilities. GrapheneOS is a security- and privacy-focused Android-based operating system. rogueFed then posted two screenshots of the Microsoft Teams call. The first was a Cellebrite Support Matrix, which lays out whether the company's tech can, or can't, unlock certain phones and under what conditions. The second screenshot was of a Cellebrite employee. According to another of rogueFed's posts, the meeting took place in October. The meeting appears to have been a sales call. The employee is a "pre sales expert," according to a profile available online.

The Support Matrix is focused on modern Google Pixel devices, including the Pixel 9 series. The screenshot does not include details on the Pixel 10, which is Google's latest device. It discusses Cellebrite's capabilities regarding 'before first unlock', or BFU, when a piece of phone unlocking tech tries to open a device before someone has typed in the phone's passcode for the first time since being turned on. It also shows Cellebrite's capabilities against after first unlock, or AFU, devices. The Support Matrix also shows Cellebrite's capabilities against Pixel devices running GrapheneOS, with some differences between phones running that operating system and stock Android. Cellebrite does support, for example, Pixel 9 devices BFU. Meanwhile the screenshot indicates Cellebrite cannot unlock Pixel 9 devices running GrapheneOS BFU. In their forum post, rogueFed wrote that the "meeting focused specific on GrapheneOS bypass capability." They added "very fresh info more coming."

schwit1 shares a report from Behind the Black: SpaceX is going to land this spaceship manned on the Moon, whether or not NASA's SLS and Orion are ready. And even if those expensive, cumbersome, and poorly designed boondoggles are ready for those first two Artemis landings, SpaceX is likely to quickly outmatch them with numerous other private missions to the Moon, outside of NASA. It has the funds to do it, and it knows it has the customers willing to buy the flights. The news comes from a detailed update SpaceX released today on the Starship lunar lander. Here's the section where SpaceX "made it clear that it sees Starship and Superheavy as its own space effort, irrelevant of NASA": "To return Americans to the Moon, SpaceX aligned Starship development along two paths: development of the core Starship system and supporting infrastructure, including production facilities, test facilities, and launch sites -- which SpaceX is self-funding representing over 90% of system costs -- and development of the HLS-specific Starship configuration, which leverages and modifies the core vehicle capability to support NASA's requirements for landing crew on and returning them from the Moon. SpaceX is working under a fixed-price contract with NASA, ensuring that the company is only paid after the successful completion of progress milestones, and American taxpayers are not on the hook for increased SpaceX costs. SpaceX provides significant insight to NASA at every stage of the development process along both paths, including access to flight data from missions not funded under the HLS contract.

Both pathways are necessary and made possible by SpaceX's substantial self-investments to enable the high-rate production, launch, and test of Starship for missions to the Moon and other purposes. Starship will bring the United States back to the Moon before any other nation and it will enable sustainable lunar operations by being fully and rapidly reusable, cost-effective, and capable of high frequency lunar missions with more than 100 tons of cargo capacity."

alternative_right shares a report from Phys.org: It is known in the scientific community that if you have a self-sustained oscillation, such as an arteriole, and you add an external stimulus at a similar but not identical frequency, you can lock the two, meaning you can shift the frequency of the oscillator to that of the external stimulus. In fact, it has been shown that if you connect two clocks, they will eventually synchronize their ticking. Distinguished Professor of Physics and Neurobiology David Kleinfeld found that if he applied an external stimulus to a neuron, the entire vasculature would lock at the same frequency. However, if he stimulated two sets of neurons at two different frequencies, something unexpected happened: some arterioles would lock at one frequency and others would lock at another frequency, forming a staircase effect.

Searching for an explanation, Kleinfeld enlisted the help of his colleague, Professor of Physics Massimo Vergassola, who specializes in understanding the physics of living systems, and then recruited Ecole Normale Superieure graduate student Marie Sellier-Prono and Senior Researcher at the Institute for Complex Systems Massimo Cencini. Together, the researchers found they could use a classical model of coupled oscillators with an intestinal twist. The gut oscillates naturally due to peristalsis -- the contracting and relaxing of muscles in the digestive tract -- and provided a simplified model over the complex network of blood vessels in the brain. The intestine is unidirectional, meaning frequencies shift in one direction in a gradient from higher to lower. This is what enables food to move in one direction from the beginning of the small intestine to the end of the large intestine.

"Coupled oscillators talk to each other and each section of the intestine is an oscillator that talks to the other sections near it," stated Vergassola. "Normally, coupled oscillators are studied in a homogeneous setting, meaning all the oscillators are at more or less similar frequencies. In our case, the oscillators were more varied, just as in the intestine and the brain." In studying the coupled oscillators in the gut, past researchers observed that there is indeed a staircase effect where similar frequencies lock onto those around it, allowing for the rhythmic movement of food through the digestive tract. But the height of the rises or breaks, the length of the stair runs or frequencies, and the conditions under which the staircase phenomenon occurred -- essential features of biological systems -- was something which had not been determined until now. The findings have been published in the journal Physical Review Letters.

An anonymous reader quotes a report from the Guardian: Australian scientists have developed roof coatings that can passively cool surfaces up to 6C below ambient temperature, as well as extract water from the atmosphere, which they say could reduce indoor temperatures during extreme heat events. One coating made from a porous film, which can be painted on to existing roofs, works by reflecting 96% of incoming solar radiation, rather than absorbing the sun's energy. It also has a high thermal emittance, meaning it effectively dissipates heat to outer space when the sky is clear. Its properties are known as passive radiative cooling. [...]

In a study, published in the journal Advanced Functional Materials, the researchers tested a prototype for six months on the roof of the Sydney Nanoscience Hub, pairing the cool paint with a UV-resistant topcoat that encouraged dew droplets to roll down into a receptacle. As much as 390 milliliters per sq meter per day could be collected for about a third of the year, the scientists found. Based on that water capture rate, an average Australian roof -- about 200 sq meters -- could provide up to 70 liters on days favorable for collecting dew, they estimate. [...]

In well-insulated buildings, a 6C decrease in roof temperature "might result in a smaller fraction of that cooling being reflected in the top level of the house," [said the study's lead author, Prof Chiara Neto of the University of Sydney], but greater temperature reductions would be expected in most Australian houses, "where insulation is quite poor." She said the coating could also help reduce the urban heat island effect, in which hard surfaces absorb more heat than natural surfaces, resulting in urban centers being 1C to 13C warmer than rural areas. The researchers found that the prototype coating was comprised of poly(vinylidene fluoride-co-hexafluoropropene), which is used in the building industry but was "not a scalable technology going forward" due to its environmental issues. However, they are now commercializing a water-based paint with similar performance that is affordable and environmentally safer, costing about the same as standard premium paints.
