  • Taxi Drivers Rarely Die of Alzheimer's
    by BeauHD on 11/08/2026 at 5:16 am

    An anonymous reader shares a report from The Conversation, written by Hatim Sharif, a civil and environmental engineer who has "spent more than two decades staring at maps" and spatial data. Sharif finds one connection especially fascinating: the link between spatial reasoning and why taxi drivers seem to have lower rates of Alzheimer's. From the report: Taxi and ambulance drivers are less likely than workers in almost any other job to die of Alzheimer's disease. That was the surprising result of a 2024 study examining the death certificates of nearly 9 million people in the U.S. [...] Of the 9 million death certificates from January 2020 to December 2022 that researchers examined, taxi and ambulance drivers had the lowest risk of dying from Alzheimer's disease out of 443 occupations. After adjusting for age, sex, race, ethnicity and education, roughly 1 in 100 taxi and ambulance drivers died of Alzheimer's, compared with 1 in 60 people overall. This pattern did not extend to other driving jobs. The researchers concluded that the key to reducing the risk of Alzheimer's was not driving itself but continuous real-time navigation: the constant work of locating yourself in space, tracking a destination and updating a mental map as conditions change. Drivers whose jobs relied on fixed or predetermined routes, like bus drivers and aircraft pilots, didn't seem to experience a similar advantage. Researchers believe the association between navigation-heavy work and lower Alzheimer's risk centers on the hippocampus, a part of the brain that governs memory and spatial navigation. It's one of the first brain regions that Alzheimer's damages: Problems with spatial navigation and orientation are among the earliest signs of the disease, sometimes surfacing before obvious memory loss. In one landmark 2000 study, neuroscientists compared the brains of licensed London taxi drivers with those of people who did not drive cabs. Their findings provided the first evidence via structural imaging that regions of the adult brain can measurably change under sustained navigational demand. To earn a license, London cabbies must memorize more than 25,000 streets within a 6-mile radius of Charing Cross, a challenge known as "The Knowledge" that takes three to four years. The researchers found that London taxi drivers had measurably more gray matter in the posterior hippocampus, a brain area tied to storing large-scale spatial maps. That volume tracked with experience: The longer someone had driven, the larger that part of the brain. The change was built through practice, not inherited. While people who are good at navigation might gravitate to this kind of job, the job itself does have an impact on the brain. Together, these two studies make a coherent case: Work that intensively exercises the hippocampus may reshape it, and that reshaping may protect against one of the most feared diseases of aging.

  • Cyber Vulnerability Sweep Picks Up Royal Navy Drones Sending Data To China
    by BeauHD on 10/08/2026 at 11:00 pm

    A routine security assessment found that cameras aboard Royal Navy Kraken unmanned surface vessels were sending "heartbeat" signals to an IP address in China. "A thorough investigation found no evidence of MoD data or systems being accessed, compromised or transmitted externally," said a Ministry of Defense spokesperson. "Our assurance and testing processes are designed to identify and address potential vulnerabilities early, and we continue to undertake routine security activity across our systems and equipment." The Register reports: According to reports, the talkative components were cameras sourced by Kraken from a third-party supplier. The incident raises questions about supply chains, audits, and cybersecurity in the British armed forces. The spokesperson said: "The first duty of government is national security, and we take the security of our equipment, networks, and data extremely seriously." Read more of this story at Slashdot.

  • A Data Breach At Shipping Giant Ceva Logistics Is Rippling Across Banks, Retailers, Steam Gamers, and Beyond
    by BeauHD on 10/08/2026 at 10:00 pm

    An anonymous reader quotes a report from TechCrunch: Ceva Logistics, one of the world's largest shipping and logistics giants, has been hacked. Several companies that rely on Ceva for shipping their products to their customers say that their personal information was also stolen in the breach. The cyberattack on Ceva is affecting at least eight warehouses across Europe used for shipping goods across the continent, the company told TechCrunch. Industry news site FreightWaves reports that the hack began on July 29 and is causing shipping delays for many of the goods in affected warehouses. Ceva is a France-headquartered shipping and logistics giant that companies around the world rely on to deliver their goods from their assembly lines to customer homes. The company, which brought in $18.3 billion in revenue in 2025, has over a thousand warehouses across the world. [...] The hack at Ceva also resulted in a data breach, affecting a large amount of personal information belonging to retail customers that Ceva relies on for delivering goods to people's home addresses. Several companies reported that hackers took their customers' names, home addresses, phone numbers, and email addresses used to place their orders from Ceva's systems. Dutch online retail giant Bol said on its website that hackers gained access to systems of its warehousing partner, Ceva, and warned that their customers' data may have been taken. Bol also said that it expects delays and some customer orders to be canceled as a result of the incident. De Bijenkorf, another Dutch luxury retailer, similarly confirmed order delays following the theft of its customers' data, per local media. Football club Ajax, banking giant ING, and eyeglass maker Ace & Tate also reported that customers' shipping information was affected. Video game giant Valve told customers that it learned on August 7 that data was taken from Ceva's systems, and alerted customers who recently bought its Steam hardware that they had personal information taken in the incident. Valve said in its note to customers, posted to Reddit, that Ceva stores their shipping and delivery information for 90 days following their order. So far, Ceva says the agency has received data breach reports from 10 organizations in relation to the incident. Read more of this story at Slashdot.

  • Valve Slowly Expands SteamOS Support On Non-Valve Hardware
    by BeauHD on 10/08/2026 at 9:00 pm

    Valve is continuing to broaden SteamOS support beyond its own hardware, with the latest beta adding "initial gamepad support" for a few recent gaming handhelds and improving compatibility for a few others. Ars Technica reports: Those newly supported handhelds include MSI's Claw 8 EX AI+, the extremely expensive, extremely powerful handheld built around Intel's Arc G3 processor that launched this summer. While SteamOS has long included beta support for "other AMD powered handhelds," Valve has only recently been working on offering compatibility with Intel-based handhelds like the MSI Claw line. This weekend's update suggests the company hasn't abandoned those efforts and that Intel chips aren't being left out of the SteamOS conversation. SteamOS 3.8.25 also newly supports the controllers built into Ayaneo's Android-focused Pocket S2 and the more recently released Windows-based Konkr Fit. Valve also says the new OS offers "improved support" for older MSI Claw devices and the OneXPlayer line of portable gaming PCs. This weekend's update follows June's SteamOS 3.8 update, which stressed "improved compatibility with recent Intel and AMD platforms." That update specifically called out improved controller support on handhelds from the likes of GPD Win, Anbernic, and OrangePi, as well as improvements for various Lenovo Legion Go, MSI Claw, and OneXPlayer devices. The report notes that the new SteamOS update also updates the Linux driver powering the new Steam Controller, "allowing it to work with 'native controller applications' even when Steam is not running."

  • First Rival Android App Store Arrives In the US Play Store
    by BeauHD on 10/08/2026 at 8:01 pm

    Aptoide has become the first third-party Android app store available directly through Google Play in the U.S. "The change is a direct result of Google's litigation with Epic, which saw a judge rule in 2024 that the Play Store would have to open up to third-party stores," notes The Verge. The change makes rival storefronts far easier to discover and install, potentially opening the door for Epic, Amazon, Samsung, Microsoft and others to distribute their own app stores through Google's store. From the report: Third-party app stores have always been available on Android, which is a more open platform than iOS in that respect. However, until now they've only been available if pre-installed on a device -- as with the Amazon Appstore on Fire tablets or Samsung's Galaxy Store -- or installed via sideloading. Listing rival storefronts within the Play Store makes them much easier for users to find and access. [...] Aptoide itself is relatively little known, but it's likely to be the first of many alternative app stores. It's presumably only a matter of time before the Epic Store makes its own appearance, and the likes of Amazon, Samsung, and other phone manufacturers may also want to put their stores in front of potential customers.

  • Wall Street Giants Partner With Nvidia On $500 Billion AI Financing Deal
    by BeauHD on 10/08/2026 at 7:00 pm

    Nvidia is working with Wall Street heavyweights on a potential $500 billion financing package for AI infrastructure (source paywalled; alternative source). The consortium includes BlackRock's Global Infrastructure Partners, Brookfield Asset Management, Goldman Sachs and KKR. The Financial Times reports: The partnership underscores Nvidia's growing efforts to raise capital for itself and its clients to continue assembling the chips, power production and data centres at the heart of the AI boom. The $5.25 trillion company has positioned itself at the centre of the AI boom, providing chips, infrastructure and software to a wide array of partners developing the technology. Nvidia's graphics processing units, or GPUs, underpin most of the leading US AI models available today. [...] The biggest cloud-computing companies, including Meta, Oracle, Microsoft, Alphabet and Amazon, have dramatically increased their spending on AI infrastructure as they look to win the race to dominate the emerging technology. Morgan Stanley projects so-called hyperscalers will spend $3.5 trillion between 2026 and 2028. That need for capital has forced technology groups to tap every source of cash they can find, including public equity, investment-grade and high-yield bonds, securitized debt, private credit and project finance markets. "[The] sheer size of the AI infrastructure build-out is unprecedented," Jim Zelter, president of Apollo, said on an earnings call earlier this month. "More than $8 trillion of capital is expected to be invested, a staggering sum. We see an enormous opportunity for private capital to finance a portion of this along with public capital."
