A person's ability to focus on everyday tasks is affected by short-term exposure to air pollution, a study has found. The Guardian: Researchers analysed data from cognitive tests completed by 26 participants before and after they were exposed either to high levels of particulate matter (PM) using smoke from a candle, or clean air for an hour. The study, published in the journal Nature Communications, found that even brief exposure to high concentrations of PM affected participants' selective attention and emotion recognition -- regardless of whether they breathed normally or just through their mouth. This can affect an individual's ability to concentrate on tasks, avoid distractions and behave in a socially appropriate way. "Participants exposed to air pollution were not as good at avoiding the distracting information," said Dr Thomas Faherty of the University of Birmingham, a co-author of the study. "So that means in daily life, you could get more distracted by things. Supermarket shopping is a good example ... it might mean that you get more distracted by impulse buys when you're walking along supermarket aisles because you're not able to focus on your task goals." The study also found that participants performed worse on cognitive tests evaluating emotional recognition after being exposed to PM air pollution.

Warner Bros. Discovery has quietly begun releasing dozens of its older films for free on YouTube, marking an unexpected shift in how the major studio handles its back catalog. Over the past month, the company has uploaded more than 30 full-length movies across five YouTube channels, without digital rights management or regional restrictions. The collection includes both critically acclaimed films like "Waiting for Guffman" and "Michael Collins," as well as commercial disappointments like the 2002 Eddie Murphy film "The Adventures of Pluto Nash." Some releases have significant historical value, such as "Oh, God!" - a 1977 George Burns comedy that earned $51 million at release (equivalent to $265 million in 2024). This move represents a departure from traditional studio practices of protecting content through strict digital rights management and paid streaming services. Warner Bros. owns multiple distribution channels, including the Max streaming service and Turner Classic Movies, which makes the decision to release these films freely on YouTube particularly notable.

An anonymous reader shares a report: The keyboard company Qwertykeys has temporarily halted all shipments to the United States in response to President Trump's tariffs on Chinese goods going into effect. The company says it's working on ways to mitigate shipping costs and that the tariffs have made it so that "all keyboards from China to the U.S. are now subject to 45% tariffs at full value." "We are closely watching the progress of the situation and really hope that there is something else we can do other than bumping the price up," the company wrote in a comment on Reddit. Qwertykeys says that its delivery partner, DHL, "now requires prepayment of 50% of the declared product value as a tariff deposit, plus a $21 processing fee per package." That would drastically raise prices for customers in the US, something Qwertykeys says is "unsustainable for both our business and customers."

Scientists have grown tooth-like structures using a combination of pig and human cells, marking a step toward potential alternatives to dental implants, researchers at Tufts University School of Dental Medicine reported. The team, led by Pamela Yelick and Weibo Zhang, cultivated the structures by seeding cells into pig tooth scaffolds and implanting them in mini pigs' jaws. After two months, the bioengineered teeth developed hard tissue layers similar to natural teeth, including dentin and cementum. While not yet fully formed teeth, the structures could eventually lead to living replacements for lost teeth, addressing limitations of current titanium implants.

DeepSeek's AI app will highly likely face a US consumer ban after topping download charts on Apple's App Store and Google Play, according to analysts at US investment bank Jefferies. The US federal government, Navy and Texas have already banned the app, and analysts expect broader restrictions using legislation similar to that targeting TikTok. While consumer access may be blocked, US developers could still be allowed to self-host DeepSeek's model to eliminate security risks, the analysts added. Even if completely banned, DeepSeek's impact on pushing down AI costs will persist as US companies work to replicate its technology, Jefferies said in a report this week reviewed by Slashdot. The app's pricing advantage remains significant, with OpenAI's latest o3-mini model still costing 100% more than DeepSeek's R1 despite being 63% cheaper than o1-mini. The potential ban comes amid broader US-China tech tensions. While restrictions on H20 chips appear unlikely given their limited training capabilities, analysts expect the Biden administration's AI diffusion policies to remain largely intact under Trump, with some quota increases possible for overseas markets based on their AI activity levels.

AMD will launch its new Radeon RX 9070-series graphics cards in March 2025, promising "high-quality gaming to mainstream players" amid struggling sales. The company's gaming division reported $563 million in Q4 2024 revenue, down 59% year-over-year. The new cards will target the same market segment as Nvidia's RTX 4070 Ti ($799) and 4070 Super ($599), featuring a 4nm TSMC manufacturing process, ML-enhanced FSR 4 upscaling, and next-generation ray-tracing accelerators. Steam Hardware Survey shows AMD's current RX 7000-series cards have minimal market presence, with only the 7900 XTX and 7700 XT registering on the list. Industry research indicates AMD sells approximately one GPU for every seven or eight sold by Nvidia. The launch timing could be opportune, as Nvidia's upcoming RTX 5070 features fewer CUDA cores than the RTX 4070 Super it replaces.

AI researchers at Stanford and the University of Washington were able to train an AI "reasoning" model for under $50 in cloud compute credits, according to a research paper. From a report: The model, known as s1, performs similarly to cutting-edge reasoning models, such as OpenAI's o1 and DeepSeek's R1, on tests measuring math and coding abilities. The s1 model is available on GitHub, along with the data and code used to train it. The team behind s1 said they started with an off-the-shelf base model, then fine-tuned it through distillation, a process to extract the "reasoning" capabilities from another AI model by training on its answers. The researchers said s1 is distilled from one of Google's reasoning models, Gemini 2.0 Flash Thinking Experimental. Distillation is the same approach Berkeley researchers used to create an AI reasoning model for around $450 last month.

Joseph Firmage, a former Silicon Valley prodigy who built a $2.5 billion web services company in the 1990s, is now being sued by investors who claim he defrauded them through an alleged antigravity machine scheme. In 1998, at the height of his success as CEO of USWeb, Firmage claimed an alien appeared in his bedroom, derailing his corporate career. He then spent decades pursuing UFO research and attempting to develop antigravity propulsion technology, raising millions from investors. Court documents allege Firmage and associates are responsible for roughly $25 million in losses through various companies and schemes. Some investors say he used elaborate ruses, including people impersonating government officials, to solicit funds. Firmage, currently in jail on elder abuse charges, maintains he was actually the victim of international scammers who exploited his access to investors.

In 2022, writer and activist Cory Doctorow coined the term "enshittification" to describe the gradual deterioration of a service or product. The term's prevalence has increased to the point that it was the National Dictionary of Australia's word of the year last year. The editors at Ars Technica, having "covered a lot of things that have been enshittified," decided to highlight some of the worst examples the've come across. Here's a summary of each thing mentioned in their report: Smart TVs: Evolved into data-collecting billboards, prioritizing advertising and user tracking over user experience and privacy. Features like convenient input buttons are sacrificed for pushing ads and webOS apps. "This is all likely to get worse as TV companies target software, tracking, and ad sales as ways to monetize customers after their TV purchases -- even at the cost of customer convenience and privacy," writes Scharon Harding. "When budget brands like Roku are selling TV sets at a loss, you know something's up." Google's Voice Assistant (e.g., Nest Hubs): Functionality has degraded over time, with previously working features becoming unreliable. Users report frequent misunderstandings and unresponsiveness. "I'm fine just saying it now: Google Assistant is worse now than it was soon after it started," writes Kevin Purdy. "Even if Google is turning its entire supertanker toward AI now, it's not clear why 'Start my morning routine,' 'Turn on the garage lights,' and 'Set an alarm for 8 pm' had to suffer." Portable Document Format (PDF): While initially useful for cross-platform document sharing and preserving formatting, PDFs have become bloated and problematic. Copying text, especially from academic journals, is often garbled or impossible. "Apple, which had given the PDF a reprieve, has now killed its main selling point," writes John Timmer. "Because Apple has added OCR to the MacOS image display system, I can get more reliable results by screenshotting the PDF and then copying the text out of that. This is the true mark of its enshittification: I now wish the journals would just give me a giant PNG." Televised Sports (specifically cycling and Formula 1): Streaming services have consolidated, leading to significantly increased costs for viewers. Previously affordable and comprehensive options have been replaced by expensive bundles across multiple platforms. "Formula 1 racing has largely gone behind paywalls, and viewership is down significantly over the last 15 years," writes Eric Berger. "Major US sports such as professional and college football had largely been exempt, but even that is now changing, with NFL games being shown on Peacock, Amazon Prime, and Netflix. None of this helps viewers. It enshittifies the experience for us in the name of corporate greed." Google Search: AI overviews often bury relevant search results under lengthy, sometimes inaccurate AI-generated content. This makes finding specific information, especially primary source documents, more difficult. "Google, like many big tech companies, expects AI to revolutionize search and is seemingly intent on ignoring any criticism of that idea," writes Ashley Belanger. Email AI Tools (e.g., Gemini in Gmail): Intrusive and difficult to disable, these tools offer questionable value due to their potential for factual inaccuracies. Users report being unable to fully opt-out. "Gmail won't take no for an answer," writes Dan Goodin. "It keeps asking me if I want to use Google's Gemini AI tool to summarize emails or draft responses. As the disclaimer at the bottom of the Gemini tool indicates, I can't count on the output being factual, so no, I definitely don't want it." Windows: While many complaints about Windows 11 originated with Windows 10, the newer version continues the trend of unwanted features, forced updates, and telemetry data collection. Bugs and performance issues also plague the operating system. "... it sure is easy to resent Windows 11 these days, between the well-documented annoyances, the constant drumbeat of AI stuff (some of it gated to pricey new PCs), and a batch of weird bugs that mostly seem to be related to the under-the-hood overhauls in October's Windows 11 24H2 update," writes Andrew Cunningham. "That list includes broken updates for some users, inoperable scanners, and a few unplayable games. With every release, the list of things you need to do to get rid of and turn off the most annoying stuff gets a little longer." Web Discourse: The rapid spread of memes, trends, and corporate jargon on social media has led to a homogenization of online communication, making it difficult to distinguish original content and creating a sense of constant noise. "[T]he enshittifcation of social media, particularly due to its speed and virality, has led to millions vying for their moment in the sun, and all I see is a constant glare that makes everything look indistinguishable," writes Jacob May. "No wonder some companies think AI is the future."

An anonymous reader quotes a report from The Guardian: Down an easy-to-miss turnoff on the A48 just outside Chepstow on the Welsh border, the gentle rumble of trucks, cranes and people at work mixes with birdsong in what is an otherwise peaceful rural setting. It is a crisp and sunny winter morning when I visit and, at first glance, the site appears to be little more than prefab containers and a car park. Yet, behind the scenes a group of men and women with expertise in diving, marine biology, technology, finance, construction and manufacturing are building something extraordinary. They have come together with a single mission statement: to make humans aquatic. Their project is called Deep (not The Deep) and the site was chosen after a global search for the perfect location to build and test underwater accommodation, which the project founders say will enable them to establish a "permanent human presence" under the sea from 2027. So far, so crazy sounding. Yet Deep is funded by a single anonymous private investor with deep pockets who wants to put hundreds of millions of pounds (if not more) into a project that will "increase understanding of the ocean and its critical role for humanity," according to a Deep spokesperson. Its leadership team remains tight-lipped not only about the amount (they will only say it is substantially more than the 100 million pounds being invested into the Deep campus near Chepstow), but also about the investor's identity. Whoever is behind it, the size of the investment means that an ambitious-sounding idea appears to be swiftly becoming a reality. [...] Mike Shackleford, Deep's chief operating officer, explains the thought process behind the project. "Back in the 1950s and 60s, there was a space race and an ocean race going on, and space won out. Space is tough to get to, but once you're up there, it's a relatively benign environment." The ocean is the opposite: it's fairly easy to get to the bottom, but once you're down there, "basically, everything wants to kill you," he jokes. "Yet, just about every oceanographer I've met says, 'You'd be shocked at how little we know about the ocean,'" Shackleford tells me. "So somebody has got to take those first steps to try to build some of the technology that will allow us to go down and study the ocean in situ." The idea of Deep's sentinels is that, initially, people will be able to stay inside for up to 28 days at a time -- though the hope is that this could one day be extended to months ... and beyond. "The goal is to live in the ocean, for ever. To have permanent human settlements in all oceans across the world," says Shackleford.
