  • Sonos Has New Devices, a New OS, and Yes, a New App
    by BeauHD on 02/09/2026 at 11:00 am

    An anonymous reader quotes a report from Wired: Sonos has a new app. Stop me if you've heard this one before. The smart speaker company, long a darling of the audio industry, undid much of the goodwill it earned with its multiroom speakers through a bevy of software updates that broke its app in 2024. Almost all app users hated it, citing the loss of features like volume control and accessibility tools meant to help blind people use the wireless speaker system. Sonos eventually owned up to the mistake, considered bringing back the old app again, then booted its CEO and marched its new leaders out to apologize profusely to win back the company's furious customers. Now, Sonos says it has a brand-new app update, infused with lots of generative AI features. The company also announced a new soundbar and its second pair of over-the-ear headphones. Sonos representatives say it doesn't want to be seen as a speaker company anymore, but as something bigger and more holistic. "For years people have been seeing us as a speaker company," says Brandon Holley, the interim hardware lead at Sonos. "What we actually are is an audio operating system." The company is calling that operating system Sonos 27, and it manifests in a few ways. [...] This is a lot of change for Sonos, something the company hasn't always handled gracefully. Sonos' home systems already aren't the easiest to set up, sometimes requiring separate apps for older products. The company may be rejiggering itself as an "audio operating system," but its software has long been the source of its troubles with getting its products to work right. Will AI smarts fix that? Maybe for its newer devices. But anyone with an existing system may still struggle. The AI features on products and in the Sonos 27 app will be opt-in, meaning you can avoid them entirely. "That really is our new approach to our app release," Patel says. "We're going to bring our customers along. We're going to listen more." That would be a good plan. Sounds like Sonos' speakers will be listening more, too. Sonos is emphasizing a more "customer-centric feedback listening approach" after the backlash to its previous redesign. Improvements include easier tab navigation, better room sorting, revamped volume controls, and new system-health tools for diagnosing connection problems. The centerpiece is Sonos 27voice, a generative AI voice assistant that can handle conversational music requests, connect with services like ChatGPT through Model Context Protocol, and power customizable "Sonos Custom Agents" for tasks such as automatically activating certain speakers. "Obviously AI is something that's very hot these days," Sonos software VP Sid Patel said. "So we have integrated various pieces of AI into our system." However, the features will only work with the newer S2 app, and Sonos cautions that "not every product will support every new feature," with detailed compatibility information coming later. Sonos is also branding its multiroom networking technology Sonos Fabric, which what Patel calls "the magic that has existed for what Sonos was built on." New Fabric features include portable surround, which lets users temporarily move speakers between rooms and have them automatically configure themselves for surround sound, and Headphone Linking, which lets users seamlessly switch audio between Sonos speakers and headphones.

  • LZ Experiment Sees Surprising Result In Search For Dark Matter
    by BeauHD on 02/09/2026 at 3:30 am

    New submitter greytree shares a report from Brown University: LUX-ZEPLIN, an experiment co-led by Brown University faculty and students, observed a particle interaction that could be interpreted as a signal from WIMPs, a dark matter candidate -- but researchers need more data to confirm. [...] The result does not yet meet the statistical threshold required to claim a discovery, but it is the most compelling hint of dark matter reported by the experiment to date. "We're very intrigued to see this event in the data, in the region where we expect dark matter to show up, and the competing backgrounds are very low," said Rick Gaitskell, a professor of physics at Brown University and the spokesperson for LZ. "With only one event, we don't want to get ahead of ourselves. We are not claiming to have seen dark matter. But we have seen something interesting that we want to share with the scientific community for their input." [...] If the anomalous event was caused by dark matter, the WIMP that generated it would likely have a mass of at least 200 GeV/c2 (gigaelectronvolts), or more than 200 times the mass of a proton. The LZ results have not reached "5-sigma" significance, the statistical threshold in physics that an event must reach to be considered a discovery. The new analysis is 2.6 sigma, meaning there is approximately a 0.5% chance that the event could be explained by known backgrounds. With additional data, researchers can test whether the finding continues to grow in significance or fades away. LZ has already accumulated the world's largest dark matter dataset and will continue to accrue WIMP search data at SURF, substantially improving their search statistics. JiJi Fan, an associate professor of physics at Brown not involved in the LZ experimental research but whose theoretical work is cited in the new LZ paper, said the new findings were "very intriguing." While the event recorded by LZ could not have been the simplest type of WIMP interaction, there are other types of possible interactions that could explain it, she said. Had a WIMP interacted in the simplest way at the high energy associated with this recent event, the detector would have recorded many recoil events at lower energies following the initial event. LZ recorded a single event, however, which requires an expanded theoretical explanation. "There are well-motivated theoretical extensions, including inelastic scattering and momentum-dependent elastic scattering, that could potentially account for this single event," Fan said. "This also sets up a target for on-going dark matter hunting, not only at direct detection experiments such as LZ but also at other complementary experimental frontiers." The results were presented in a scientific talk at the 2026 TeV Particle Astrophysics conference in Japan on Tuesday, Sept. 1. A paper detailing the finding can be found here (PDF).

  • GoPro Says It's Moving Into Data Centers As Part of a $285 Million Merger
    by BeauHD on 01/09/2026 at 11:00 pm

    GoPro plans to expand into AI infrastructure through a $285 million merger with optical-photonics company Starman Optical, whose transceivers will give the action-camera maker a foothold in the fast-growing data center market. GoPro also plans to push into defense, robotics, aerospace, and government markets while continuing its existing camera business. Engadget reports: Starman's optical transceivers are expected to fall under its umbrella, "extending the Company's reach into the large and rapidly growing market for AI infrastructure in optical transceivers," according to a press release. GoPro is also planning a push into the defense, government, robotics and aerospace sectors, bolstered by the combined company's IP, optics and imaging capabilities. [...] As Reuters notes, GoPro briefly reached a valuation of $4 billion on its first day as a publicly traded company in 2014. Its stock has struggled in recent years, but the share price received a boost on Monday when it was revealed that YouTuber and filmmaker Markiplier (Mark Fischbach) had become GoPro's largest individual shareholder after acquiring an 8.5 percent stake. The move follows a similar pivot made by the struggling shoe retailer Allbirds in April when it announced a pivot to AI compute infrastructure, sending the stock soaring more than 700%.

  • Who Is John Ternus, the New Apple CEO?
    by BeauHD on 01/09/2026 at 10:00 pm

    John Ternus has officially taken over as Apple CEO after 15 years under Tim Cook, stepping up from his role as senior vice president of hardware engineering. A 25-year Apple veteran who helped oversee products including AirPods, Apple Watch, Vision Pro, Apple silicon, and the new MacBook Neo, Ternus now inherits the challenge of pushing Apple forward in AI while Cook stays on as executive chairman. TechCrunch reports: Ternus has worked at Apple for nearly half of his life -- now 51 years old, he has been with the company for 25 years. He joined Apple's product design team in 2001 as only his second job out of college (his first was at a small maker of virtual-reality devices called Virtual Research Systems). By 2013, Ternus was a VP of hardware engineering and was promoted to the SVP role in 2021. [...] Ternus previously reported to Cook, who he considers a mentor, and led all of hardware engineering at Apple. That's a pretty big deal for a company that's known for ubiquitous hardware like the iPhone and the MacBook. [...] Ternus' earliest project at Apple involved scrutinizing parts for the Apple Cinema Display, an early desktop monitor. "At some point in my first year, I found myself at a supplier facility. I was far away from home. Well past midnight, I was using a magnifying glass to count the number of grooves on the head of a screw ... and I was arguing with the supplier because these parts had 35 grooves. They were supposed to have 25," Ternus recalled in his commencement speech. "I distinctly remember stepping back for a minute and thinking, 'What the hell am I doing? Is this normal?'" As Ternus climbed the corporate ladder, his responsibilities grew. He may no longer spend as much time analyzing screws, but he still seems to take pride in getting the little details right. In a recent interview, when Ternus was asked about his favorite memory of Steve Jobs, he mentioned the former Apple co-founder's attention to craftsmanship. "[Jobs] was moving a piece of furniture, a chest of drawers, and pulled it away from the wall and looked at the back and was just reflecting on, you know, that the carpenter who made it had made it beautiful," Ternus said. "It finished the back as beautifully as the rest of it, even though nobody was going to see it, right? And I think about that all the time because I think that perfectly exemplifies what we do here." From there, he went on to lead the hardware development behind products across the Apple ecosystem, overseeing launches like AirPods, Apple Watch, and the Vision Pro. He also had a hand in major technical upgrades at Apple, like Apple's transition from Intel chips to its own proprietary Apple silicon. Most recently, Ternus was involved in the production of the MacBook Neo, Apple's new, more affordable laptop model that lowers costs through some clever trade-offs in hardware design, like using an iPhone chip to power the device. "We never want to ship junk. We want to ship great products that have that Apple experience, that Apple quality. To do that with the Neo required building something completely new from the ground up ... leveraging both the technologies we'd been developing like Apple silicon, but also the kind of expertise that we've developed over many, many years of building Macs, and building phones, and building iPads, and all of these things," Ternus told Tom's Guide.

  • Anthropic's Claude Fable 5.1 and Mythos 5.1 Arrive With a 75% Cost Reduction For Fable Cache Reads
    by BeauHD on 01/09/2026 at 9:00 pm

    Anthropic has released Claude Fable 5.1 and Mythos 5.1, two versions of the same underlying model aimed at longer-running agentic work. "For enterprise buyers, however, the release is about more than another round of benchmark gains," reports VentureBeat. "Anthropic is simultaneously changing the economics of running persistent agents, reducing the cost of cached context by 75%, and introducing a new security architecture called Enterprise Frontier Safeguards, or EFS, designed to let organizations retain monitoring data inside infrastructure they control." From the report: Those changes arrive at a particularly consequential moment. Over the past several weeks, Anthropic and the U.K. AI Security Institute have disclosed incidents in which earlier Claude models, running under unusually permissive cybersecurity evaluation conditions, took unauthorized actions against real systems. Anthropic temporarily paused external cyber evaluations and has since introduced additional containment and monitoring before resuming them. Taken together, Fable 5.1 looks less like a conventional model refresh than an attempt to solve three increasingly intertwined enterprise problems: how to make agents capable enough to finish difficult work, economical enough to leave running for hours, and governable enough to give access to sensitive systems.
