Submission + - Alibaba secretly hijacking computer audio system (ppc.land)

An anonymous reader writes: A developer using Bluetooth headphones accidentally caught Chinese e-commerce giant Alibaba secretly hijacking his computer's audio system without making a single sound.

When his wireless headphones refused to switch audio to his phone while browsing AliExpress, he inspected the site's hidden code. He discovered background scripts holding his computer's audio pipeline wide open.

Alibaba was using the browser's WebAudio API to run invisible sound waves at zero volume. By measuring tiny hardware differences in how each computer processes those signals, the site created a unique digital fingerprint to track devices.

Because the secret audio path stayed active, it froze his Bluetooth connection while quietly scraping hardware memory, screen dimensions, and network data in the background.

Submission + - Vote by Mail? Only for "the Right people" ... (thehill.com)

An anonymous reader writes: The United States Postal Service (USPS) announced Friday new eligibility guidelines for mail-in ballots, complying with President Trump's March executive order restricting the practice — despite a federal court later striking it down.

USPS's 95-page unpublished report, slated for an official release on Aug. 26, detailed how it would distribute mail-in ballots for November's midterms. The requirements closely resemble Trump's blocked mandate, which ordered states to submit a list of eligible, voting citizens if they want their voters to received mail-in ballots.

The service's new policy, echoing Trump's order, gives states 60 days before the Nov. 3 midterms to notify USPS if they intend to submit a list of eligible voters based on citizenship data. Only then will USPS send mail-in or absentee ballots to the states' respective residents.

In June, Postmaster General David Steiner affirmed his intention to comply with the president's directive, telling senators in June that the policy will ensure "the right ballots are going to the right people."

Two months later, U.S. District Judge Indira Talwani moved to block the order's enforcement nationwide, arguing its implementation would create unnecessary "confusion" and "chaos" ahead of November's midterms.

"That it is now less than 90 days before the November 3, 2026 midterm elections underscores the critical need for an injunction to prevent Defendants from changing election rules on the eve of the election," Talwani wrote in her ruling.

In response to the judge's ruling, White House spokesperson Lauren Bis told The Hill the administration "will continue lawfully enacting the agenda President Trump was elected to enact — which includes the safety and security of American elections."

Trump has been a critic of mail-in ballots, frequently reiterating unproven claims that the voting method has been a vehicle for wide-spread voter fraud.

In late June, the president slammed a Supreme Court decision that affirmed mail-in ballots may count if they are postmarked by Election Day but arrive afterward. The president called it a "tremendous loss in the Supreme Court."

Nearly a third of ballots cast in the 2024 general election were submitted by mail, according to a June U.S. Election Assistance Commission (EAC) report. The ballots accounted for 30.3 percent of votes cast that year, well above pre-pandemic levels.

Submission + - Microsoft Blames Windows Gaming Issues on RGB Lighting Devices (bleepingcomputer.com)

joshuark writes: Microsoft says ongoing issues causing games to crash or fail to launch after installing the August 2026 Windows updates may be caused by peripherals with RGB lighting. Microsoft explained when it confirmed it's investigating on Wednesday, this known issue affects games like ARC Raiders, MARVEL Tkon: Fighting Souls, and The Finals on systems running Windows 11 24H2 and 25H2.

"Following the release of Windows updates on August 11, 2026 (KB5121003) and later, Microsoft received reports of issues involving inability to run games as expected," Microsoft said on the Windows release health dashboard.

On impacted PCs, users are also experiencing gaming freezes, "EXCEPTION_ACCESS_VIOLATION" errors, and even unexpected system restarts.

Embark Studios, the Swedish video game developer behind ARC Raiders and The Finals, also said these issues are caused by inpoutx64.sys, but added that they stem from changes made to the Windows kernel driver.

"We're aware of a crash that has been impacting some players since the most recent Windows update (KB5121003). This is a crash related to the file inpoutx64.sys, which changed with the Windows update," Embark said on Monday.

Until Microsoft ships an official fix, Embark shared a multi-step temporary workaround that requires users to delete the service and remove the inpoutx64 file from the Windows drivers folder.

Submission + - China Joins Europe In Scrapping Windows For Linux (zdnet.com)

An anonymous reader writes: According to a Bloomberg report, attributed to China's Ministry of State Security, the country has ordered some government agencies to drop Windows 10 China Government Edition for Chinese-made Linux distributions. Why not Windows 11? Because China, like many other non-US governments, no longer trusts American companies with their software and services. This approach is all about digital sovereignty. In addition, even before the recent trend of governments outside America moving away from Windows, Beijing has started a long-running push to replace foreign technology in sensitive systems with domestic, open-source alternatives.

[...] The Chinese government did not specify which Linux versions would replace Windows 10. However, the stock prices of Chinese Linux suppliers, Kylin Software and Tongxin Software Technology (commonly known as UnionTech), immediately jumped. These companies' respective operating systems, Kylin OS (no relation to Ubuntu Kylin) and UnionTech OS (UOS), were already positioned as domestic desktop and server replacements for Windows in government, state-owned enterprise, and critical-infrastructure environments. [...] Huawei's HarmonyOS 2, which began as an Android variant but is now a proprietary mobile and Internet of Things (IoT) operating system, is also being developed into a PC platform. HarmonyOS 2 won't be deployed anytime soon. Kylin and UOS are the only mature desktops that are ready for institutional desktop deployments.

[...] ... this transition won't be easy. For agencies now moving off the government Windows build, the issue will be more demanding than simply swapping one desktop interface for another. Migration requires application testing, peripheral and driver validation, identity system integration, document-format compatibility, staff retraining and, in many cases, replacement or adaptation of Windows-dependent line-of-business software. The report provides no details on exactly how this transformation will occur. But the speed of the shift suggests that these issues are already being addressed in China's centralized managed desktop stack.

Submission + - AI Boosted Homework Scores, Then Exam Scores Dropped (economist.com)

An anonymous reader writes: Students and school children are increasingly using artificial intelligence. A survey last year by Chegg, an ed-tech firm, found that 80% of rich-world undergraduates used it in their studies. More recent polls put the figure at 94% in Britain and 93% in Germany. Such widespread adoption has fueled concerns about the impact the technology might be having on learning. Teachers report marking identikit essays that they suspect are churned out by ChatGPT. Yet firm evidence on AI’s educational effects has been lacking.

David Stromberg of Stockholm University and Victor Lei and Wu Yanhui of the University of Hong Kong set out to fill the gap. They tracked 27,000 pupils aged 12-18 in China, where AI adoption has been fast. Around 80% reported using models such as Doubao and DeepSeek; the other 20% formed the control group.

The results are eye-opening. After six months, pupils using AI saw their average homework score rise by 18% across all subjects. The time they took to complete each assignment fell from an average of 64 minutes to 45. But come exam time, the same students scored 20% below their classmates who had not called on AI’s help. Homework scores once predicted exam performance; now those who score highest are, perversely, more likely to do worse in exams.

Submission + - Microsoft Cut Office 2021's Support to Five Years (microsoft.com)

An anonymous reader writes: Microsoft will end support for Office 2021 on October 13, 2026, with no extension and no paid Extended Security Updates. After that date the perpetual-license apps keep running, but Word, Excel, PowerPoint, and Outlook stop getting security patches, so any newly found vulnerability stays open. The notable part for anyone who bought a one-time license: this is a five-year support window, half the ten-year lifecycle older perpetual Office releases received, and the same cutoff also ends the one-year Windows 10 consumer reprieve. Microsoft's pitch is to move to a Microsoft 365 subscription, though Office LTSC 2024 stays supported to 2029. A retailer guide runs through the Office 2021 upgrade options for holdouts.

Submission + - Nations hiding censorship in cybercrime bills. UN treaty could make things worse (fire.org)

An anonymous reader writes: The likely outcome here is obvious: The treaty will streamline unfree countries’ involvement with other unfree countries’ repression and pressure freer ones into helping, too. And it can all take place confidentially, without the knowledge of the public or even those being targeted . . .

And as though existing national laws punishing political expression aren’t enough, the treaty could even incentivize governments to enact harsher penalties on expressive acts. After all, if you’d like other nations to assist you in punishing your critics on the internet, you’ll want to ensure their expression qualifies for inclusion under the treaty’s definition of “serious crimes.”

It's already happening in the UK

Submission + - American Airlines Changed Passengers' Flights w/o Asking and No Human Oversight (inc.com)

schwit1 writes: In recent years, American Airlines has embraced artificial intelligence. Now the new technology appears to be changing flight tickets.

Earlier this week, columnist Marc Thiessen took to social media to voice his frustration with American‘s rebooking system. He claimed the airline rebooked his connecting flight in Chicago without his knowledge when his inbound flight was delayed. “Since when do you change my itinerary without asking?” Thiessen wrote on X.

The rebooking automation appears to be part of an American Airlines system called AURA (for AUtomated ReAccommodation). The system, which initially rolled out in 2023, is meant to help passengers with their connecting flights. “Our Automated Reaccommodation tool proactively rebooks customers impacted by flight cancellations and delays, and exchanges tickets,” the company said on its site. However, the automated system appears to have negatively impacted more than one traveler.

Below Thiessen’s post, media consultant Beverly Hallberg replied that American had done the same thing to her the day before. “I had to call and switch my connecting flight back to the original itinerary, and I had enough time to do that since we were stuck on the tarmac for so long. But, like you, they didn’t ask,” she wrote on X.

Submission + - FCC Abolishes Gigabit Speed Goal, Suggesting It Is Unfair to Slower Technologies (arstechnica.com)

An anonymous reader writes: The Federal Communications Commission last week eliminated the gigabit speed goal established during the Biden administration and declared that current levels of broadband deployment in the US are acceptable. Though fiber networks have routinely offered such speeds for years, the FCC said the gigabit speed goal is not “technologically neutral,” suggesting that it isn’t fair to other, slower technologies.

In 2024, the FCC raised its broadband benchmark to 100Mbps downstream and 20Mbps upstream, setting the new standard by which to judge whether deployment is reasonable and timely. The FCC at the time also set a long-term speed goal of 1Gbps download speeds paired with 500Mbps upload speeds, saying it would use the goal “as a guidepost for evaluating our efforts to encourage deployment.” Republican Brendan Carr, who is now the FCC chairman, never liked that long-term goal. He proposed abolishing it last year, and the change was finalized on August 14 in the FCC’s latest broadband deployment report. The reports are mandated by Section 706 of the Telecommunications Act.

“As part of our return to following the plain language of Section 706, we adopt our proposal from the Notice [of Inquiry] to abolish without replacement the long-term goal of 1,000/500 Mbps established in the 2024 Report,” the order said. “A long-term goal is not mentioned in Section 706 and could appear to violate our obligation to conduct our analysis in a technologically neutral manner. At present, it is impossible to predict long-term technological developments and the evolution of consumer preferences." The FCC said that comments submitted by cable industry group NCTA and wireless industry group CTIA “support our reasoning for abolishing the long-term goal.”

Submission + - Low emission zone led to better lung size and function among London children (theguardian.com)

AmiMoJo writes: Children’s lungs grew bigger and stronger after the most polluting vehicles were restricted from entering London, a study has found. Examinations of London schoolchildren before and after the introduction of the city’s ultra-low emission zone (Ulez) found a restoration of lung capacity that had been stunted by exposure to pollution. The researchers said the findings were a vindication of the low-emission zone policy, which had been criticized as a burden on motorists.

Air pollution from traffic has stunted the development of children’s lungs in London for decades. Previous research found that by the age of eight or nine, children from the most polluted areas had 5-10% less lung capacity than their peers elsewhere. That impairment, which scientists said was the result of exposure to nitrogen dioxide, put them at increased risk as adults of developing respiratory diseases, such as asthma and chronic obstructive pulmonary disease, cardiovascular and metabolic disease, and premature death.

Submission + - The Surprisingly Deep Physics of the Pinewood Derby (turboderby.com)

An anonymous reader writes: A five-ounce block of pine racing down a Cub Scout track is a closed-system physics problem: it converts a fixed budget of gravitational potential energy into forward motion, rotational energy trapped in the spinning wheels, and heat lost to friction. Winning means wasting less than the next kid. The professional racing scene that emerged in the early 2000s now optimizes three levers: potential energy, friction, and rotational inertia, with CNC-machined axles, sub-gram wheels, and cars balanced to ride on only three wheels to cut rotational losses. Wired's Rhett Allain ran the numbers in 2010, and the problem earned a peer-reviewed treatment in Mechanical Sciences. Counterintuitively, weight belongs at the rear, and lighter wheels help more than their mass suggests.

Submission + - New Gel Regrows Tooth Enamel (sciencedaily.com) 2

fahrbot-bot writes: ScienceDaily is reporting that researchers have developed a fluoride-free gel that could help rebuild damaged tooth enamel, something the body cannot naturally replace once it is lost. Inspired by the proteins that guide enamel formation in infancy, the gel fills microscopic cracks, acting as as a framework, and draws calcium and phosphate from saliva to grow a new mineral layer that closely matches healthy enamel.

The material draws calcium and phosphate ions from saliva and uses them to guide the controlled formation of new mineral crystals. This process is known as epitaxial mineralization. In simple terms, the new crystals grow in alignment with the tooth's existing structure, allowing them to connect with the natural tissue beneath them rather than forming a separate, poorly organized coating.

According to the researchers, this organized growth helps the repaired surface recover both the microscopic architecture and the physical properties of healthy enamel.

In addition, when applied to exposed dentine, the gel can grow an enamel like mineral layer over the surface. This could help reduce tooth sensitivity while also creating a stronger surface for dental restorations to bond to.

The researchers tested the regenerated material under conditions intended to reproduce the stresses teeth experience in daily life. These included repeated brushing, chewing forces, and contact with acidic foods that can gradually dissolve enamel.

The results showed that the restored tissue displayed mechanical behavior similar to that of healthy natural enamel, suggesting it may be durable enough for practical dental use.

In lab tests on human teeth using human saliva, the process took about 24 hours for the initial crystallization, reaching 80% of the enamel's original strength in 2 weeks. Human trials have recently begun.

The study is published in Nature and also discussed on Instagram.
