  • FDA Approves First Wearable Device to Monitor Glucose, Ketone Levels
    by BeauHD on 25/08/2026 at 9:01 pm

    The FDA has authorized the first wearable in the U.S. to continuously monitor ketone levels and the first device globally to track both ketones and glucose together in a single system. From a report: [Abbott's] Libre Duo 10 Day continuously measures both glucose and ketone levels in the fluid just beneath the skin every minute, day and night. Readings are transmitted wirelessly to a compatible smartphone, where users can view current glucose and ketone levels and whether those values are trending up or down. The device also can send automatic alerts if ketone levels reach a concerning threshold. The FDA noted that ketone information should be interpreted in the context of glucose readings and symptoms. Ketones are produced when the body uses fat instead of glucose for energy. When ketone levels rise too high, patients with diabetes can develop diabetic ketoacidosis (DKA), a serious complication that can progress quickly and become life-threatening without prompt treatment. Until now, patients who needed ketone monitoring had to test separately using methods that provided a single measurement at one point in time. Those tests could not show whether ketone levels were rising or falling. For patients with diabetes -- particularly those at higher risk for DKA -- continuous glucose and ketone monitoring may provide earlier warning of metabolic deterioration and support timelier sick-day management, hydration, insulin adjustment, and escalation of care when clinically appropriate.

  • Canadian Streaming Content Becomes a US Trade Issue
    by BeauHD on 25/08/2026 at 8:00 pm

    Canada's cultural-content rules have become a flashpoint in its trade fight with the U.S., after American negotiators reportedly demanded that Ottawa drop requirements for streaming services to promote Canadian and French-language content. Canada refused, even as it has already backed away from some financial levies on streamers. "We were not prepared to compromise on our sovereignty, the protection of the French language, and our culture," Prime Minister Mark Carney said in a speech on Saturday after trade talks collapsed. CBC.ca reports: Ottawa has long required broadcasters to promote and support Canadian content (Cancon), all the way back to song quotas for AM radio stations. In 1991, the government brought in the Broadcasting Act. The law states that "the Canadian broadcasting system shall be effectively owned and controlled by Canadians" and that the Canadian broadcasting system should "serve to safeguard, enrich and strengthen the cultural, political, social and economic fabric of Canada." But decades later, the rising popularity in Canada of streaming platforms such as Netflix, YouTube, Amazon Prime and Spotify raised questions about Cancon and broadcasting rules. Video and audio streaming services were not, for example, required to support and promote Cancon, but their TV and radio counterparts were. Looking to address the imbalance, the former Trudeau government brought forward a bill in 2022 to update the Broadcasting Act, called the Online Streaming Act. "Canadian broadcasters have invested in and introduced us to the incredible Canadian programs that so many of us love. We are updating our laws so online streamers have to contribute in a similar and equitable way," a 2022 government news release said. The legislation was controversial from the start, with the government and supporters saying it was a necessary evolution of Canada's media laws in the digital age, while opponents expressed concerns that it was overreach and an attempt to regulate the internet. American streamers and digital media companies opposed the legislation fiercely. The bill passed with amendments and became law in April 2023, but the government delegated much of its interpretation -- including how much money streamers would have to contribute to Cancon -- to Canada's broadcast regulator, the Canadian Radio-television and Telecommunications Commission (CRTC). But getting streaming companies to pay up has been a long and confusing saga. [...]. As for why the U.S. government is so invested in the issue? Mariane Bourcheix-Laporte, a postdoctoral fellow in the communication studies and media arts department at McMaster University in Hamilton, said it could be about power. "The Americans have had, since after World War II, a very strong cultural policy of pushing out American content into the world," Bourcheix-Laporte, who has worked with the CRTC, said. "This has been a strategy -- a soft-power strategy -- for the American government, in parallel to their military strategies and political alliances strategies." Read more of this story at Slashdot.

  • Perplexity and Nvidia Launch Fully Local AI Agent With Zero Token Costs
    by BeauHD on 25/08/2026 at 7:00 pm

    Perplexity and Nvidia have launched "Portable Computer," a local-first version of Perplexity's agent platform that runs AI models, files, tools, and workflows directly on Nvidia-powered Linux hardware. Local tasks incur no token charges and keep data on-device by default, with users asked for permission before the system escalates a step to a cloud model. VentureBeat reports: For Nvidia, which has spent the past two years selling the world on trillion-dollar AI data centers, the announcement signals something subtler but strategically important: the chipmaker believes local AI has crossed a threshold from hobbyist curiosity to practical tool -- and it wants to sell the hardware that runs it. "Local AI reached an inflection point," said Nader, Nvidia's director of developer technology, who focuses on developer tooling and open source. "For the longest time, it was hobbyists and enthusiasts, and they were running these quantized models that were quantized down to be super tiny... And while that's cool, it's not super practical. But all that changed with a lot of these new open source models that have come out that are super useful." [...] Portable Computer arrives today for Pro, Max, Enterprise Pro, and Enterprise Max subscribers on Linux, with Windows support following in September. Any RTX GPU with at least 24GB of VRAM -- roughly a GeForce RTX 3090 or newer -- clears the bar, a threshold Nate called "sort of the floor where we really want to make sure that we can deliver a great experience, but balance that with making it broadly available."

  • AI Is Hitting Entry-Level Jobs Hardest, Stanford Study Finds
    by BeauHD on 25/08/2026 at 6:00 pm

    An anonymous reader quotes a report from Ars Technica: For years, AI industry watchers of all stripes have been warning of a coming jobs apocalypse driven by ultra-intelligent AI systems that will be able to replicate most human tasks more cheaply. Now, newly updated research from Stanford University economists suggests AI seems to be causing significant entry-level job losses for younger workers in some fields, even as older workers appear largely unaffected so far. The August 2026 edition of "Canaries in the Coal Mine? Six Facts about the Recent Employment Effects of Artificial Intelligence" updates and revises a paper of the same name published last year with fresh data and refined statistics. In that update, the Stanford researchers find the employment trends they identified for entry-level workers last year are persisting and expanding. Specifically, employment levels for workers ages 22 to 25 in the most "AI-exposed" occupations are now 19 percent below those of their peers in fields less exposed to AI disruption. Last year, that gap measured just 13 percent. [...] Digging deeper into the data, the researchers found that this phenomenon is mainly manifesting itself through lower hiring rates for entry-level workers in AI-impacted fields, rather than increased firings or employees quitting. They also found that the labor market effects among this age group were mostly seen in lower overall employment, rather than reduced pay rates. But not all jobs that show potential for AI "disruption" are created equal, the researchers found. In its Economic Index, Anthropic differentiates between queries related to tasks that are "automative" (i.e., fully replacing work previously done by a human) or "augmentative" (i.e., helping human workers be more effective at tasks they are still needed for). By this measure, jobs like "accountants and auditors" and "receptionists and information clerks" were among those judged most susceptible to AI automation, while jobs like "chief executive" and "registered nurse" were among those using AI augmentation most often. Unsurprisingly, jobs where AI automation is prevalent are the ones showing the worst relative employment levels for entry-level workers these days. "The findings are consistent with automation-oriented uses of AI substituting for labor while complementary uses are associated with flat or rising employment," the researchers write. Interestingly, the researchers found that the impact is strongest in entry-level jobs built around "codified" knowledge, which is the formal, documented skills that AI can more easily replicate. Meanwhile, experienced workers in roles relying on tacit, practice-based knowledge have seen stronger employment growth. Read more of this story at Slashdot.

  • Waymo Is Expanding to Germany
    by BeauHD on 25/08/2026 at 5:00 pm

    Waymo plans to launch its robotaxi service in Munich by the end of 2027, marking the Google-owned company's first expansion into the European Union. "It already operates in 11 cities in the United States and has applied for a license in the United Kingdom to launch its robotaxis in London this year," notes Reuters. From the report: The Google subsidiary will start rolling out vehicles in the German city this year, which will be manually driven while the company "starts with high-definition mapping of local street networks" and testing with safety drivers, Waymo said in a statement. "Bavaria is determined to live up to its pioneering role and be an international leader in autonomous driving," Florian Herrmann, the head of the Bavarian state chancellery, said in the statement. "Now we need to move quickly from testing to real-world deployment." [...] German authorities gave autonomous vehicles the green light in 2021 to operate in the country in approved geographical areas. Other countries are looking at following suit, though the EU's broader autonomous driving rules are set by the U.N. Read more of this story at Slashdot.

    by BeauHD on 25/08/2026 at 4:00 pm

    Apple has unveiled a new Mac mini with either its new M6 chip or the M5 Pro chip released earlier this year. It adds faster CPU, GPU, storage, and AI performance along with Wi-Fi 7, Bluetooth 6, and 2.5Gb Ethernet as standard. There's also a new higher starting price of $899, which is up from the previous $799 base price and far above the $599 starting price of the 2024 model. MacRumors reports: The M6 chip is equipped with a 12-core CPU and a 12-core GPU, up from a 10-core CPU and 10-core GPU in the M5 chip. In addition, the M6 chip features the first-ever dual Neural Engine with two 16-core engines, up from one in previous chips. The M6 chip has up to 170GB/s memory bandwidth, up from 153GB/s for the M5 chip. Apple said the Mac mini with the M6 chip delivers up to 40% faster CPU performance, up to 4x faster performance for AI tasks in particular, up to 2x faster graphics performance, and up to 2x faster storage speeds compared to the previous-generation model with the 10-core M4 chip, 32GB of unified memory, and 2TB of storage. There are two M5 Pro configurations available, including one with a 15-core CPU and a 16-core GPU, and another with an 18-core CPU and a 20-core GPU. Both of these models are equipped with a single 16-core Neural Engine for AI tasks. For both the M6 and M5 Pro configurations, Apple said the Mac mini now includes Neural Accelerators in each GPU core for the first time. Read more of this story at Slashdot.
