A controversial VAR (Video Assistant Referee) decision helped eliminate Atletico Madrid from the Champions League after Julian Alvarez's penalty was disallowed for a near-microscopic double touch. Despite referee Szymon Marciniak standing just feet away and missing the infraction, VAR officials intervened without the typically required "clear and obvious error" standard.

This incident has exemplified the paradox of video review technology in football: introduced to reduce controversies, VAR has instead multiplied them. Technical implementation varies significantly across competitions -- some MLS stadiums have fewer cameras available for review than others -- creating inconsistent application. The Premier League claims VAR increased correct decisions from 82% to 96%, yet the remaining errors dominate match-day discourse. The Guardian adds: VAR incidents are now so endemic that Norway's clubs were compelled to vote on whether use of the technology should be scrapped two weeks ago. Ultimately, they decided to stick with VAR, even though most of the country's professional clubs want rid of it.

In the Norwegian league, the use of VAR has become so unpopular that fans felt they had no choice but to pelt the field with fishcakes in protest, which may or may not be A Norwegian Thing. Ultimately, the decision on whether to keep or scrap VAR devolved into a power struggle of a sort between Norway's 32 top professional clubs and the federation. Whereas the vote to introduce VAR -- which Norway didn't adopt until 2023, years later than most European countries -- was conducted by those pro teams alone, the decision to scrap it was voted on by every club in the country.

Several amateur clubs told the Guardian they felt conflicted about being dragged into a fight about a technology not in use at their level. Had it been left up to the pros, VAR would have been scrapped, by a 19-13 margin. Instead, the federation orchestrated a vote among all the country's clubs to force the retention of VAR -- and avoid becoming the first nation to scrap it -- prevailing by 321 votes to 129.

Apple is planning a new AirPods feature that allows the earbuds to live-translate an in-person conversation into another language, Bloomberg reports, citing people with knowledge of the matter. From the report: The capability will be offered as part of an AirPods software upgrade due later this year, said the people, who asked not to be identified because the effort is private. It will be tied to iOS 19, the upcoming update to Apple's mobile-device operating system.

Windows Defender has begun identifying WinRing0 -- a kernel-level driver used by numerous hardware monitoring applications -- as malicious software, causing widespread functionality issues for affected tools. The driver, which provides low-level hardware access necessary for reading fan speeds, controlling RGB lighting, and monitoring system components, is being quarantined due to potential security vulnerabilities that could be exploited by malware.

WinRing0 gained popularity among developers because it's one of only two freely available Windows drivers capable of accessing the SMBus registers needed for hardware monitoring functions. The affected applications include Fan Control, OpenRGB, MSI Afterburner, LibreHardwareMonitor, and multiple others that rely on this driver to communicate with system hardware.

After raising rates last June for customers on some of its older plans, T-Mobile is pushing up costs again -- but it's not entirely clear how many people are affected. From a report: According to a memo obtained by CNET and sent to T-Mobile employees early this morning, some people will see a $5 per-line increase beginning with their April or May bills.

The memo by Jon Freier, president of T-Mobile's consumer group, states that customers affected by the price hike should be notified by the end of today, March 13. Only those who receive a notice will see the rate increase.

Freier cites the "rising costs over the past several years" as the impetus behind the price push. Other carriers are facing the same headwinds, such as Verizon last December and this January, and AT&T last January and June.

On March 9, older Chromecast and Chromecast Audio devices stopped working due to an expired device authentication certificate authority that made them untrusted by Google's apps. While unofficial apps like VLC continue to function, Google's fix will require either updating client apps to bypass the issue or replacing the expired certificates, a process that could take weeks; however, Google has since announced it is beginning a gradual rollout of a fix. The Register reports: Tom Hebb, a former Meta software engineer and Chromecast hacker, has published a detailed analysis of the issue and suggests a fix could take more than a month to prepare. He's also provided workarounds here for folks to try in the meantime. We spoke to Hebb, and he says the problem is this expired device authentication certificate authority. [...] The fix is not simple. It's either going to involve a bit of a hack with updated client apps to accept or workaround the situation, or somehow someone will need to replace all the key pairs shipped with the devices with ones that use a new valid certificate authority. And getting the new keys onto devices will be a pain as, for instance, some have been factory reset and can't be initialized by a Google application because the bundled cert is untrusted, meaning the client software needs to be updated anyway.

Given that the product family has been discontinued, teams will need to be pulled together to address this blunder. And it does appear to be a blunder rather than planned or remotely triggered obsolescence; earlier Chromecasts have a longer certificate validity, of 20 years rather than 10. "Google will either need to put in over a month of effort to build and test a new Chromecast update to renew the expired certificates, or they will have to coordinate internally between what's left of the Chromecast team, the Android team, the Chrome team, the Google Home team, and iOS app developers to push out new releases, which almost always take several days to build and test," Hebb explained. "I expect them to do the latter. A server-side fix is not possible."

So either a week or so to rush out app-side updates to tackle the problem, or much longer to fix the problem with replaced certs. Polish security researcher Maciej Mensfeld also believes the outage is most likely due to an expired device authentication certificate authority. He's proposed a workaround that has helped some users, at least. Hebb, meanwhile, warns more certificate authority expiry pain is looming, with the Chromecast Ultra and Google Home running out in March next year, and the Google Home Mini in January 2027.

An anonymous reader quotes a report from Ars Technica: Meta plans to test out X's algorithm for Community Notes to crowdsource fact-checks that will appear across Facebook, Instagram, and Threads. In a blog, Meta said the testing in the U.S. would begin March 18, with about 200,000 potential contributors already signed up. Anyone over 18 with a Meta account more than six months old can also join a waitlist of users who will "gradually" and "randomly" be admitted to write and rate cross-platform notes during initial beta testing.

Meta claimed that borrowing X's approach would result in "less biased" fact-checking than relying on experts alone. But the social media company will delay publicly posting any notes until it's confident that the system is working. For users of Meta platforms, notes could help flag misleading content overlooked by prior fact-checking efforts. However, Meta confirmed that users will not be allowed to add notes correcting misleading advertisements, which means notes won't help reduce scam ads that The Guardian reported last August have been spreading on Facebook for years. Meta confirmed that the company plans to tweak X's algorithm over time to develop its own version of community notes, which "may explore different or adjusted algorithms to support how Community Notes are ranked and rated."

Mozilla is urging Firefox users to update their browsers to version 128 or later (or ESR 115.13 for extended support users) before March 14, 2025, to avoid security risks and add-on disruptions caused by the expiration of a key root certificate. "On 14 March a root certificate (the resource used to prove an add-on was approved by Mozilla) will expire, meaning Firefox users on versions older than 128 (or ESR 115) will not be able to use their add-ons," warns a Mozilla blog post. "We want developers to be aware of this in case some of your users are on older versions of Firefox that may be impacted." BleepingComputer reports: A Mozilla support document explains that failing to update Firefox could expose users to significant security risks and practical issues, which, according to Mozilla, include:

- Malicious add-ons can compromise user data or privacy by bypassing security protections.
- Untrusted certificates may allow users to visit fraudulent or insecure websites without warning.
- Compromised password alerts may stop working, leaving users unaware of potential account breaches.

It is noted that the problem impacts Firefox on all platforms, including Windows, Android, Linux, and macOS, except for iOS, where there's an independent root certificate management system. Mozilla says that users relying on older versions of Firefox may continue using their browsers after the expiration of the certificate if they accept the security risks, but the software's performance and functionality may be severely impacted.

Google is continuing its quest to get more people to use Gemini, and it's doing that by giving away even more AI computing. From a report: Today, Google is releasing a raft of improvements for the Gemini 2.0 models, and as part of that upgrade, some of the AI's most advanced features are now available to free users. You'll be able to use the improved Deep Research to get in-depth information on a topic, and Google's newest reasoning model can peruse your search history to improve its understanding of you as a person.

[...] With the aim of making Gemini more personal to you, Google is also plugging Flash Thinking Experimental into a new source of data: your search history. Google stresses that you have to opt in to this feature, and it can be disabled at any time. Gemini will even display a banner to remind you it's connected to your search history so you don't forget.

Microsoft says that some USB printers will start printing random text after installing Windows updates released since late January 2025. From a report: The known issue affects Windows 10 (version 22H2) and Windows 11 (versions 22H2 and 23H2), but according to an update to the Windows release health dashboard, the latest Windows 11 24H2 is not impacted.

"After installing the January 2025 Windows preview update (KB5050092), released January 29, 2025, or later updates, you might observe issues with USB connected dual-mode printers that support both USB Print and IPP Over USB protocols," Redmond explains. "You might observe that the printer unexpectedly prints random text and data, including network commands and unusual characters."

On affected systems, users will often see erroneously printed text that begins with the header "POST /ipp/print HTTP/1.1," followed by other IPP (Internet Printing Protocol) related issues headers. These printing issues are more frequent when the printer is turned on or reconnected after being disconnected. Affected users will observe the printer unexpectedly printing when the print spooler sends IPP protocol messages to the printer and the printer driver is installed on the Windows device.

Mozilla has warned that the U.S. Department of Justice's proposed remedies in its antitrust case against Google would harm independent browsers and reduce competition in the browser market. The DOJ and several state attorneys general last week filed revised proposed remedies in the U.S. v. Google search case that would prohibit all search payments to browser developers, a move Mozilla says would disproportionately impact smaller players.

"These proposed remedies prohibiting search payments to small and independent browsers miss the bigger picture -- and the people who will suffer most are everyday internet users," said Mark Surman, President of Mozilla. Unlike Apple and Microsoft, which generate revenue from hardware and operating systems, Mozilla relies primarily on search revenue to fund browser development. Mozilla argues that cutting these payments would not solve search dominance but would instead strengthen the position of tech giants.

Mozilla also warned that the proposal threatens its ability to maintain Gecko, one of only three major browser engines alongside Google's Chromium and Apple's WebKit. "If we lose our ability to maintain Gecko, it's game over for an open, independent web," Surman said, noting that even Microsoft abandoned its browser engine in 2019. "If Mozilla is unable to sustain our browser engine, it would severely impact browser engine competition and mean the death of the open web as we know it -- essentially, creating a web where dominant players like Google and Apple, have even more control, not less."

Firefox serves 27 million monthly active users in the U.S. and nearly 205 million globally.

Britain's competition watchdog has concluded that Apple and Google are stifling competition in the UK mobile browser market, following an investigation by the Competition and Markets Authority (CMA). The inquiry found Apple's iOS policies particularly restrictive, requiring all browsers to use its WebKit engine while giving Safari preferential access to features.

Apple's practice of pre-installing Safari as the default browser also reduces awareness of alternatives, despite allowing users to change defaults. Google faces similar criticism for pre-installing Chrome on most Android devices, though investigators noted both companies have recently taken steps to facilitate browser switching. The probe identified Apple's revenue-sharing arrangement with Google -- which pays a significant share of search revenue to be the default iPhone search engine -- as "significantly reducing their financial incentives to compete."

Parents who are worried about their children being on Roblox should not let them use it, the chief executive of the gigantic gaming platform has said. From a report: The site, which is the most popular in the UK among young gamers aged eight to 12, has been dogged by claims of some children being exposed to explicit or harmful content through its games, alongside multiple reported allegations of bullying and grooming.

But its co-founder and CEO Dave Baszucki insisted that the company is vigilant in protecting its users and pointed out that "tens of millions" of people have "amazing experiences" on the site. When asked what his message is to parents who don't want their children on the platform, Mr Baszucki said: "My first message would be, if you're not comfortable, don't let your kids be on Roblox." [...] "That sounds a little counter-intuitive, but I would always trust parents to make their own decisions," he told BBC News in an exclusive interview.

Using the Summit supercomputer at the Department of Energy's Oak Ridge National Laboratory, researchers have modeled a key component of nucleotide excision repair (NER) called the pre-incision complex (PInC), which plays a crucial role in DNA damage repair. Their study, published in Nature Communications, provides new insights into how the PInC machinery orchestrates precise DNA excision, potentially leading to advancements in treating genetic disorders, preventing premature aging, and understanding conditions like xeroderma pigmentosum and Cockayne syndrome. Phys.Org reports: "Computationally, once you assemble the PInC, molecular dynamics simulations of the complex become relatively straightforward, especially on large supercomputers like Summit," [said lead investigator Ivaylo Ivanov, a chemistry professor at Georgia State University]. Nanoscale Molecular Dynamics, or NAMD, is a molecular dynamics code specifically designed for supercomputers and is used to simulate the movements and interactions of large biomolecular systems that contain millions of atoms. Using NAMD, the research team ran extensive simulations. The number-crunching power of the 200-petaflop Summit supercomputer -- capable of performing 200,000 trillion calculations per second -- was essential in unraveling the functional dynamics of the PInC complex on a timescale of microseconds. "The simulations showed us a lot about the complex nature of the PInC machinery. It showed us how these different components move together as modules and the subdivision of this complex into dynamic communities, which form the moving parts of this machine," Ivanov said.

The findings are significant in that mutations in XPF and XPG can lead to severe human genetic disorders. They include xeroderma pigmentosum, which is a condition that makes people more susceptible to skin cancer, and Cockayne syndrome, which can affect human growth and development, lead to impaired hearing and vision, and speed up the aging process. "Simulations allow us to zero in on these important regions because mutations that interfere with the function of the NER complex often occur at community interfaces, which are the most dynamic regions of the machine," Ivanov said. "Now we have a much better understanding of how and from where these disorders manifest."

Google says its new open-source AI model, Gemma 3, achieves nearly the same performance as DeepSeek AI's R1 while using just one Nvidia H100 GPU, compared to an estimated 32 for R1. ZDNet reports: Using "Elo" scores, a common measurement system used to rank chess and athletes, Google claims Gemma 3 comes within 98% of the score of DeepSeek's R1, 1338 versus 1363 for R1. That means R1 is superior to Gemma 3. However, based on Google's estimate, the search giant claims that it would take 32 of Nvidia's mainstream "H100" GPU chips to achieve R1's score, whereas Gemma 3 uses only one H100 GPU.

Google's balance of compute and Elo score is a "sweet spot," the company claims. In a blog post, Google bills the new program as "the most capable model you can run on a single GPU or TPU," referring to the company's custom AI chip, the "tensor processing unit." "Gemma 3 delivers state-of-the-art performance for its size, outperforming Llama-405B, DeepSeek-V3, and o3-mini in preliminary human preference evaluations on LMArena's leaderboard," the blog post relates, referring to the Elo scores. "This helps you to create engaging user experiences that can fit on a single GPU or TPU host."

Google's model also tops Meta's Llama 3's Elo score, which it estimates would require 16 GPUs. (Note that the numbers of H100 chips used by the competition are Google's estimate; DeepSeek AI has only disclosed an example of using 1,814 of Nvidia's less-powerful H800 GPUs to server answers with R1.) More detailed information is provided in a developer blog post on HuggingFace, where the Gemma 3 repository is offered.

New submitter CInder123 shares a report from TechSpot: Apple is undertaking one of the most significant software overhauls in its history, aiming to revamp the user interface across iPhone, iPad, and Mac devices. This ambitious update, set for release later this year, will fundamentally transform the look and feel of Apple's operating systems, enhancing consistency and the user experience.

The updates are part of iOS 19 and iPadOS 19, codenamed "Luck," and macOS 16, dubbed "Cheer," according to Bloomberg's Mark Gurman. He cited sources who requested anonymity since the project has yet to be officially announced. These major upgrades will introduce a new design language while simplifying navigation and controls. Apple's push for consistency across platforms aims to create a seamless user experience when switching between devices. Currently, applications, icons, and window styles vary significantly across macOS, iOS, and visionOS, leading to a disjointed experience.

An anonymous reader quotes a report from Ars Technica: On Wednesday, Google DeepMind announced two new AI models designed to control robots: Gemini Robotics and Gemini Robotics-ER. The company claims these models will help robots of many shapes and sizes understand and interact with the physical world more effectively and delicately than previous systems, paving the way for applications such as humanoid robot assistants. [...] Google's new models build upon its Gemini 2.0 large language model foundation, adding capabilities specifically for robotic applications. Gemini Robotics includes what Google calls "vision-language-action" (VLA) abilities, allowing it to process visual information, understand language commands, and generate physical movements. By contrast, Gemini Robotics-ER focuses on "embodied reasoning" with enhanced spatial understanding, letting roboticists connect it to their existing robot control systems. For example, with Gemini Robotics, you can ask a robot to "pick up the banana and put it in the basket," and it will use a camera view of the scene to recognize the banana, guiding a robotic arm to perform the action successfully. Or you might say, "fold an origami fox," and it will use its knowledge of origami and how to fold paper carefully to perform the task.

In 2023, we covered Google's RT-2, which represented a notable step toward more generalized robotic capabilities by using Internet data to help robots understand language commands and adapt to new scenarios, then doubling performance on unseen tasks compared to its predecessor. Two years later, Gemini Robotics appears to have made another substantial leap forward, not just in understanding what to do but in executing complex physical manipulations that RT-2 explicitly couldn't handle. While RT-2 was limited to repurposing physical movements it had already practiced, Gemini Robotics reportedly demonstrates significantly enhanced dexterity that enables previously impossible tasks like origami folding and packing snacks into Zip-loc bags. This shift from robots that just understand commands to robots that can perform delicate physical tasks suggests DeepMind may have started solving one of robotics' biggest challenges: getting robots to turn their "knowledge" into careful, precise movements in the real world. DeepMind claims Gemini Robotics "more than doubles performance on a comprehensive generalization benchmark compared to other state-of-the-art vision-language-action models."

Google is advancing this effort through a partnership with Apptronik to develop next-generation humanoid robots powered by Gemini 2.0. Availability timelines or specific commercial applications for the new AI models were not made available.

D-Wave researchers have published findings in Science demonstrating what they call "quantum supremacy" by showing their quantum annealers can solve problems beyond the reach of classical computers. The team, led by Andrew D. King, demonstrated area-law scaling of entanglement in model quench dynamics of two-, three- and infinite-dimensional spin glasses.

The research shows quantum annealers rapidly generating samples that closely match solutions to the Schrodinger equation, supporting observed stretched-exponential scaling in matrix-product-state approaches. According to the paper, D-Wave's processors completed these magnetic materials simulations in under 20 minutes, while the same calculations would require nearly a million years on Oak Ridge National Laboratory's supercomputers.

The claim hasn't gone unchallenged. Miles Stoudenmire from the Flatiron Institute's Center for Computational Quantum Physics argues that classical computers can achieve comparable results using methods developed since D-Wave's initial findings. "We're just saying, 'Look, this one problem at this one time didn't beat classical computers. Try again,'" Stoudenmire noted. The quantum computing community has increasingly shifted terminology from "supremacy" to "advantage" or "utility," focusing on solving practical business or scientific problems faster, more accurately, or more economically than classical alternatives.

Several Asian airlines have tightened restrictions on portable battery chargers amid growing concerns about fire risks, following a January blaze that destroyed an Air Busan aircraft in South Korea. South Korean airlines now require passengers to keep portable chargers within arm's reach rather than in overhead bins, a rule implemented March 1 to ease public anxiety, according to the Transportation Ministry. Taiwan's EVA Air and China Airlines have banned using or charging power banks on flights but still allow them in overhead compartments.

Thai Airways announced a similar ban last Friday, citing "incidents of in-flight fires on international airlines." Battery-related incidents on U.S. airlines have increased from 32 in 2016 to 84 last year, with portable chargers identified as the most common culprit, according to Federal Aviation Administration data. The International Civil Aviation Organization has banned lithium-ion batteries from cargo holds since 2016, though no industry standard exists for regulating power banks.

Global sales of smartwatches have fallen for the first time, new figures indicate, in large part due to a sharp decline in the popularity of market leader, Apple. From a report: Market research firm Counterpoint says 7% fewer of the devices were shipped in 2024 compared to the year before. Shipments of Apple Watches fell by 19% in that period, Counterpoint says. It blames the slump on a lack of new features in Apple's latest devices, and the fact a rumoured high-end Ultra 3 model never materialised.

The Federal Trade Commission asked a judge in Seattle to delay the start of its trial accusing Amazon of duping consumers into signing up for its Prime program, citing resource constraints. CNBC: Attorneys for the FTC made the request during a status hearing on Wednesday before Judge John Chun in the U.S. District Court for the Western District of Washington. Chun had set a Sept. 22 start date for the trial. Jonathan Cohen, an attorney for the FTC, asked Chun for a two-month continuance on the case due to staffing and budgetary shortfalls.

The FTC's request to delay due to staffing constraints comes amid a push by the Trump administration's Department of Government Efficiency to reduce spending. DOGE, which is led by tech baron Elon Musk, has slashed the federal government's workforce by more than 62,000 workers in February alone. "We have lost employees in the agency, in our division and on our case team," Cohen said.
