An anonymous reader quotes a report from The Independent: The two professions associated with the lowest levels of death due to Alzheimer's disease may be surprising. Taxi and ambulance drivers were found to have the lowest proportion of deaths of more than 440 occupations that were considered in a new observation-based study from Massachusetts physicians. Alzheimer's disease is a type of dementia that affects memory, thinking, and behavior. It impacts millions of Americans and is one of the top 10 causes of death in the US.

While the study's findings cannot confirm a direct link between the professions and reduced risk, its researchers said they raise the possibility that memory-intensive driving occupations could be associated with some protection. "We view these findings not as conclusive, but as hypothesis-generating," they said, noting that no resolute conclusions can be drawn about cause and effect. The jobs require frequent spatial and navigational processing: the ability to sense and incorporate information about the location of objects around them. Although, the trend was not seen in other related jobs, like driving a bus or piloting an aircraft. It was also not seen in other forms of dementia, which suggests changes in the hippocampus region of the brain -- which is used for spatial memory and navigation -- may account for the reduction.

The hippocampus, located deep within the brain, has been shown to be enhanced in London taxi drivers compared to the general population. The region is also one of the parts of the brain involved in the development of Alzheimer's disease. [...] The authors acknowledged that there were limitations, including that individuals who are at higher risk of developing Alzheimer's disease may be less likely to enter driving occupations. However, they said this is unlikely because disease symptoms typically develop after working age. "Further research is necessary to definitively conclude whether the spatial cognitive work required for these occupations affects the risk of death from Alzheimer's disease and whether any cognitive activities can be potentially preventive," they said. The research has been published in the journal The BMJ.

The implementation of the Corporate Transparency Act -- a law aimed at getting shell companies to disclose their true ownership -- was paused again just days before a reporting deadline was set to take effect, as a federal appeals court handed the case to a panel for further consideration. From a report: In a court filing late Thursday, the Fifth Circuit Court of Appeals vacated a stay on a national injunction the court had issued Monday that reinstated the Jan. 1 reporting deadline for millions of companies. The lifting of the stay means the January filing deadline will be postponed once again and bars the government and the Treasury Department from enforcing the law, pending oral arguments before the court's so-called merits panel, a group of judges tasked with considering appeals.

The Corporate Transparency Act, a bipartisan law passed in 2021 to curtail the use of anonymous shell companies and help track flows of illicit money, would require companies to file beneficial ownership information with the Treasury's Financial Crimes Enforcement Network or face the possibility of penalties such as fines and jail time. The law could cover more than 32 million small businesses nationwide.

On Christmas Day, the social media app Bluesky added a list of Trending topics to its mobile app, allowing users to see which subjects are popular among its community. The Verge reports: The new feature can be found by selecting the search icon (the magnifying glass), which appears at the bottom of the screen on the mobile app and on the left sidebar on the web. Lists of Trending and Recommended subjects now appear below the search bar. Tap on any topic, and you will be able to access the associated posts. [...] According to the announcement, the new feature is "V1" (it is marked as a Beta on the app) and "we will be iterating with your feedback."

An anonymous reader quotes a report from The Guardian: Despite having an endless amount of music to pair with their short, scrollable videos, TikTok users have been raiding the back catalogues of artists from yesteryear including Bronski Beat and Sade to soundtrack their posts. This year set a new high for use of old tracks on British TikTok posts, with tunes more than five years old accounting for 19 out of its 50 top tracks this year. It is the highest proportion since TikTok started monitoring the trend in 2021, when just 8 out of the 50 tracks were from back catalogues. The trend is also global, with 20 out of the top 50 tracks worldwide coming from back catalogues, led by 80s hit Forever Young by German synth-pop band Alphaville. Here are the top back catalogue tracks (must be more than five years old) on TikTok this year:

1. Blood Orange - Champagne Coast [2011]: 1.1m posts
2. Alphaville - Forever Young [1984]: 458,000 posts
3. Redbone - Come and Get Your Love [1974]: 386,000 posts
4. Tom Odell - Another Love [2012]: 238,000 posts
5. Pavement - Harness Your Hopes [1999]: 219,000 posts
6. Natasha Bedingfield - Unwritten [2004]: 207,000 posts
7. Christina Aguilera - Genie in a Bottle [1999]: 207,000 posts
8. Sade - Kiss of Life [1993]: 194,000 posts
9. Sophie Ellis Bextor - Murder on the Dancefloor [2001]: 191,000 posts
10. The Fray - Look After You [2005]: 188,000 posts

An anonymous reader quotes a report from Ars Technica: Apparently Hertz's purging of electric vehicles from its fleet isn't going fast enough for the car rental giant. A Reddit user posted an offer they received from Hertz to buy the 2023 Tesla Model 3 they had been renting for $17,913. Hertz originally went strong into EVs, announcing a plan to buy 100,000 Model 3s for its fleet by the end of 2021, but 16 months later had acquired only half that amount. The company found that repair costs -- especially for Teslas, which averaged 20 percent more than other EVs -- were cutting into its profit margins. Customer demand was also not what Hertz had hoped for; last January, it announced plans to sell off 20,000 EVs.

Asking its customers if they want to purchase their rentals isn't a new strategy for Hertz. "By connecting our rental customers who opt into our emails to our sales channels, we're not only building awareness of the fact that we sell arsenal but also offering a unique opportunity to someone who may be in the market for the same car they have on rent," Hertz communications director Jamie Line told The Verge. Hertz is advertising a limited 12-month, 12,000-mile powertrain warranty for each EV, and customers will have seven days to return the car in case of profound buyer's regret.

Meta is betting that characters generated by AI will fill its social media platforms in the next few years as it looks to the fast-developing technology to drive engagement with its 3 billion users. From a report: The Silicon Valley group is rolling out a range of AI products, including one that helps users create AI characters on Instagram and Facebook [non-paywalled source], as it battles with rival tech groups to attract and retain a younger audience.

"We expect these AIs to actually, over time, exist on our platforms, kind of in the same way that accounts do," said Connor Hayes, vice-president of product for generative AI at Meta. "They'll have bios and profile pictures and be able to generate and share content powered by AI on the platform ... that's where we see all of this going," he added. Hayes said a "priority" for Meta over the next two years was to make its apps "more entertaining and engaging," which included considering how to make the interaction with AI more social.

A wave of fraudulent copyright takedowns on YouTube has exposed vulnerabilities in the platform's content moderation system, enabling anonymous users to threaten creators' channels through false legal claims, The Verge is reporting. Several gaming content creators, including a channel with 1.5 million subscribers, received takedown notices from someone impersonating Nintendo's legal team. Though YouTube acknowledged the false claims, the company declined to explain how it verifies takedown requests or detail measures to prevent abuse of its copyright system.

Facial recognition technology is poised to replace traditional passports globally, marking the biggest shift in travel documentation since World War 1. Airports across Finland, Canada, Netherlands, UAE, UK, Italy, US, and India are testing passport-free systems, with Singapore already implementing the technology for its residents and departing visitors.

The systems typically store passport data digitally on smartphones, using face recognition cameras at airports to match travelers against stored photos. Singapore officials report over 1.5 million people have used their system, while Finnish trials showed identity checks taking just eight seconds.

theodp writes: In 2012, now-Microsoft President Brad Smith unveiled Microsoft's National Talent Strategy, a two-pronged strategy that called for tech visa restrictions to be loosened to allow tech companies to hire non-U.S. citizens to fill jobs until more American schoolchildren could be made tech-savvy enough to pass hiring standards. Shortly thereafter, tech-backed nonprofit Code.org emerged (led by Smith's next-door neighbor Hadi Partovi with Smith as a founding Board member) with a mission to ensure that U.S. schoolchildren started receiving 'rigorous' computer science education instruction. Around the same time, Mark Zuckerberg's FWD.us PAC launched (with support from Smith, Partovi, and other tech leaders) with a mission to reform tech visa policy to meet tech's need for talent.

Fast forward to 2024, and Newsweek reports the debate over tech immigration policy has been revived, spurred by the recent appointment of Sriram Krishnan as senior policy adviser for AI at the Trump White House. Comments by far-right political activist Laura Loomer on Twitter about Krishnan's call for loosening Green Card restrictions were met with rebuttals from prominent tech leaders who are also serving as members of the Trump transition team. Entrepreneur David Sacks, who Trump has tapped as his cryptocurrency and AI czar, took to social media to clarify that Krishnan advocates for removing country caps on green cards, not eliminating caps entirely, aiming to create a more merit-based system. However, the NY Times reported that Sacks discussed a much broader visa reform proposal with Trump during a June podcast ("What I will do is," Trump told Sacks, "you graduate from a college, I think you should get automatically, as part of your diploma, a green card to be able to stay in this country"). Elon Musk, the recently appointed co-head of Trump's new Dept. of Government Efficiency (DOGE) had Sacks' and Krishnan's backs (not unexpected -- both were close Musk advisors on his Twitter purchase), tweeting out "Makes sense" to his 209 million followers, lamenting that "the number of people who are super talented engineers AND super motivated in the USA is far too low," reposting claims crediting immigrants for 36% of the innovation in the U.S., and taking USCIS to task for failing to immediately recognize his own genius with an Exceptional Ability Green Card (for his long-defunct Zip2 startup).

Vivek Ramaswamy, who Trump has tapped to co-lead DOGE with Musk, agreed and fanned the Twitter flames with a pinned Tweet of his own explaining, "The reason top tech companies often hire foreign-born -- first-generation engineers over "native" Americans isn't because of an innate American IQ deficit (a lazy -- wrong explanation). A key part of it comes down to the c-word: culture." (Colorado Governor Jared Polis also took to Twitter to agree with Musk and Ramaswamy on the need to import 'elite engineers'). And Code.org CEO Partovi joined the Twitter fray, echoing the old we-need-H1B-visas-to-make-US-schoolchildren-CS-savvy argument of Microsoft's 2012 National Talent Strategy. "Did you know 2/3 of H1B visas are for computer scientists?" Partovi wrote in reply to Musk, Loomer, and Sachs. "The H1B program raises $500M/year (from its corporate sponsors) and all that money is funneled into programs at Labor and NSF without focus to grow local CS talent. Let's fund CS education." The NYT also cited Zuckerberg's earlier efforts to influence immigration policy with FWD.us (which also counted Sacks and Musk as early supporters), taking note of Zuck's recent visit to Mar-a-Lago and Meta's $1 million donation to Trump's upcoming inauguration.

So, who is to be believed? Musk, who attributes any tech visa qualms to "a 'fixed pie' fallacy that is at the heart of much wrong-headed economic thinking" and argues that "there is essentially infinite potential for job and company creation ['We should let anyone in the country who is hardworking and honest and will be a contributor to the United States,' Musk has said]"? Or economists who have found that immigration and globalization is not quite the rising-tide-that-raises-all-boats it's been cracked up to be?

Microsoft is warning that Windows 11 installations using USB or CD media created with October or November 2024 security updates may be unable to receive future security patches.

The bug affects version 24H2 installations made between October 8 and November 12, but does not impact systems updated through Windows Update or the Microsoft Update Catalog. Microsoft advised users to rebuild installation media using December 2024 patches while it works on a permanent fix for the issue, which primarily affects business and education environments.

Apple's $3,499 Vision Pro headset has failed to gain widespread adoption despite advanced technology, with consumers preferring discreet wearables like smartwatches. The Verge: Nearly a year from launch, though, Apple hasn't done enough to demonstrate why the Vision Pro should be a potential showcase of the future of computing. It's taking a long time to put together its immersive content library, and while those are great demonstrations of what's possible, the videos have been short and isolating. There aren't many great games, either.

Yes, Apple keeps adding cool new software features. The wide and ultra widescreen settings for using a Mac display seem exceptionally useful. But those are pretty specific options for pretty specific use cases. There still isn't an immediate, obvious reason to buy a Vision Pro the way there usually is with the company's newest iPhones and Macs. If I bought a Vision Pro today, I wouldn't know what to do with it besides give myself a bigger Mac screen or watch movies, and I don't think either of those are worth the exorbitant price.

Airports are facing a growing nuisance as travelers increasingly watch videos and take calls on speakerphone without headphones, creating tension among passengers at gates and lounges.

Flight attendants at American Airlines, Alaska Air, and Delta have begun addressing the issue through announcements and website notices, though enforcement remains challenging, WSJ reports. Passengers report confrontations rarely end well, with offenders often dismissive or hostile when asked to use headphones. The story adds: The headphones-optional attitude isn't limited to air travel. Podcasts and sports games blare in open-plan offices. You can catch snippets of conversations on the sidewalk, some phones held aloft for video calls. Transit authorities in big cities have struggled to get passengers to keep their music to themselves on subways and commuter trains.

Witnesses say offenders span the generational and socioeconomic spectrum, from grandparents on speakerphone to toddlers on iPads and from first class to coach.

Air travel already overloads the senses with a cacophony of boarding announcements, beeping vehicles and crying babies. U.S. airlines generally don't allow voice and video calls in the air. But by takeoff, the damage has been done.

Apple may be worth one and a half Googles now, but the world's most valuable company needs its relationship with the world's largest search engine to keep clicking. From a report: Such was evident Monday when Apple filed papers seeking to participate in the penalty phase of the Justice Department's antitrust case against Google. The search giant lost that case in August and is now battling the government over what remedies are appropriate. The DOJ has a long wish list that includes breaking the company up, forcing Google to make key search and user data available to potential rivals, and stopping the payments Google makes to partners such as Apple.

The payments to Apple alone now reportedly equate to about $20 billion annually, and make Google the default search engine on devices like the iPhone. Apple didn't confirm any specific amounts in its filing, but did say the company feels compelled to "protect its commercial interests." Analysts widely estimate that the payments from Google are nearly pure profit for Apple, given relatively little incremental cost to generate that revenue. For Apple, $20 billion is about 16% of the operating income reported for the company's fiscal year that ended in September.

Modern LED headlights are significantly brighter and more glaring than traditional halogen bulbs, creating dangerous driving conditions, lighting experts report. The newer lights produce an intense, concentrated beam that is bluer and more disorienting, particularly affecting older drivers. "Headlights are getting brighter, smaller and bluer. All three of those things increase a particular kind of glare. It's called discomfort glare," said Daniel Stern, chief editor of Driving Vision News.

The annual defense policy bill signed by President Joe Biden Monday evening allocates $3 billion to help telecom firms remove and replace insecure equipment in response to recent incursions by Chinese-linked hackers. From a report: The fiscal 2025 National Defense Authorization Act outlines Pentagon policy and military budget priorities for the year and also includes non-defense measures added as Congress wrapped up its work in December. The $895 billion spending blueprint passed the Senate and House with broad bipartisan support.

The $3 billion would go to a Federal Communications Commission program, commonly called "rip and replace," to get rid of Chinese networking equipment due to national security concerns. The effort was created in 2020 to junk equipment made by telecom giant Huawei. It had an initial investment of $1.9 billion, roughly $3 billion shy of what experts said was needed to cauterize the potential vulnerability.

Calls to replenish the fund have increased recently in the wake of two hacking campaigns by China, dubbed Volt Typhoon and Salt Typhoon, that saw hackers insert malicious code in U.S. infrastructure and break into at least eight telecom firms. The bill also includes a watered down requirement for the Defense Department to tap an independent third-party to study the feasibility of creating a U.S. Cyber Force, along with an "evaluation of alternative organizational models for the cyber forces" of the military branches.

An anonymous reader quotes a report from The Guardian: More than 140 Facebook content moderators have been diagnosed with severe post-traumatic stress disorder caused by exposure to graphic social media content including murders, suicides, child sexual abuse and terrorism. The moderators worked eight- to 10-hour days at a facility in Kenya for a company contracted by the social media firm and were found to have PTSD, generalized anxiety disorder (GAD) and major depressive disorder (MDD), by Dr Ian Kanyanya, the head of mental health services at Kenyatta National hospital in Nairobi. The mass diagnoses have been made as part of lawsuit being brought against Facebook's parent company, Meta, and Samasource Kenya, an outsourcing company that carried out content moderation for Meta using workers from across Africa.

The images and videos including necrophilia, bestiality and self-harm caused some moderators to faint, vomit, scream and run away from their desks, the filings allege. The case is shedding light on the human cost of the boom in social media use in recent years that has required more and more moderation, often in some of the poorest parts of the world, to protect users from the worst material that some people post. The lawsuit claims that at least 40 moderators experienced substance misuse, marital breakdowns, and disconnection from their families, while some feared being hunted by terrorist groups they monitored. Despite being paid eight times less than their U.S. counterparts, moderators worked under intense surveillance in harsh, warehouse-like conditions.

An anonymous reader shares a report: Over the past year, OpenAI has dropped not-so-subtle hints about its revived interest in robotics: investing in startups developing hardware and software for robots such as Figure and Physical Intelligence and rebooting its internal robotics software team, which it had disbanded four years ago.

Now, OpenAI could be taking that interest to the next level. The company has recently considered developing a humanoid robot, according to two people with direct knowledge of the discussions. As a refresher, humanoid robots typically have two arms and two legs, distinguishing them from typical robots in a warehouse or factory that might have a single arm repeatedly performing the same task on an assembly line. Developers of humanoid robots think it will be easier for them to handle tasks in the physical world -- which is tailored to humans -- than it would be to change our physical environments to suit new robots.

Apple has long avoided directly purchasing Nvidia's chips and is now developing its own AI server chip with Broadcom, aiming for production by 2026, The Information reported Tuesday, shedding broader light on why the two companies don't get along so well.

The relationship deteriorated after a 2001 meeting where Steve Jobs accused Nvidia of copying technology from Pixar, which he then controlled. Relations worsened in 2008 when Nvidia's faulty graphics chips forced Apple to extend MacBook warranties without full compensation.

Rather than buying Nvidia's dominant AI processors directly like its tech peers, the Information reports, Apple rents them through cloud providers while also using Google's custom chips for training large AI models. The company's new chip project, code-named Baltra, marks its most ambitious effort yet to reduce reliance on external AI processors, despite being one of the largest indirect users of Nvidia chips through cloud services.

ASUS computer owners have been reporting widespread alarm after a Christmas-themed banner suddenly appeared on their Windows 11 screens, accompanied by a suspicious "Christmas.exe" process in Task Manager.

The promotional campaign, first reported by WindowsLatest, was delivered through ASUS' pre-installed Armoury Crate software. It displays a large wreath banner that covers one-third of users' screens. The unbranded holiday display, which can interrupt gaming sessions and occasionally crashes applications, has triggered security concerns among users who initially mistook it for malware.

PCWorld's Jon Phillips pays tribute to Gordon Mah Ung, "our hardware guru, host of The Full Nerd, exemplary tech journalist, and very good friend." He passed away over the weekend after a hard-fought battle with pancreatic cancer. He was 58. From the report: With more than 25 years' experience covering computer tech broadly and computer chips specifically, Gordon's dogged reporting, one-of-a-kind personality, and commitment to journalistic standards touched many, many lives. He will be profoundly missed by co-workers, industry sources, and the PC enthusiasts who read his words and followed him as a video creator.

Gordon studied journalism at San Francisco State University and then worked as a police reporter for the Contra Costa Times in the late 1990s. In 1997, he joined Computerworld (a PCWorld sister publication) before I recruited him to join boot magazine (later re-launched as Maximum PC), where he would ultimately lead hardware coverage for 16 years.
