  • Russian Launch Site Mishap Shows Perilous State of Storied Space Program
    by BeauHD on 02/12/2025 at 7:00 am

    A Soyuz launch at Baikonur damaged Russia's only launchpad capable of sending astronauts and crucial propellant to the ISS. "The rocket itself headed to space without incident, taking three astronauts -- Sergey Kud-Sverchkov and Sergei Mikaev of Russia and Chris Williams of NASA -- to the space station," reports the New York Times. "But the force of the rocket's exhaust shoved a service platform used for prelaunch preparations out of its protective shelter. The platform fell into the flame trench below." From the report: Photos and videos of the launch site the next day showed the platform out of place and mangled. "It's heavily damaged," said Anatoly Zak, who publishes RussianSpaceWeb.com, a close tracker of Russia's space activities, "and so probably it will have to be rebuilt. Maybe some of the hardware can be reused. But it fell down, and it's destroyed." This is the latest embarrassment for the once-proud Russian space program, which the United States relied on from 2011 to 2020 to get NASA astronauts to orbit. The incident also raises questions about the future of the International Space Station if the launchpad cannot be quickly repaired. In a statement issued on Friday, Roscosmos, the state corporation in charge of the Russian space program, confirmed unspecified "damage" at the launchpad. "All necessary parts needed for repairs are at our disposal, and the damage will be dealt with in the near future," it said. Read more of this story at Slashdot.

  • Samsung Debuts Its First Trifold Phone
    by BeauHD on 02/12/2025 at 5:13 am

    At an event in Seoul on Tuesday, Samsung unveiled the Galaxy Z TriFold, a dual-hinged smartphone that unfolds into a 10-inch tablet (source paywalled; alternative source). It launches on Dec. 12 in Korea for about $2,450. The company plans to sell the phone in the U.S., but hasn't shared pricing. Bloomberg reports: Samsung's device has a different hinge design, folding inward from two sides whereas the Mate models take on a Z shape when being folded. When closed, the TriFold's outer screen offers similar dimensions to a regular smartphone. But when unfurled, it provides a tablet-style experience with a 10-inch display, larger than the panel on the Galaxy Z Fold 7. In the tablet-like mode, each of the device's screens can independently run a different app. This provides the equivalent of three separate 6.5-inch bar-style handsets side by side. Using Samsung's DeX software, which has been tweaked for this particular hardware type, you can also run a desktop-like experience directly on the large inner display. (Other Samsung phones must be plugged into an external monitor to activate DeX mode.) In DeX, the TriFold can operate as many as four distinct workspaces that can each run five apps simultaneously. To preempt concerns about potential breakage, Samsung said it has refined the phone's hinges, aluminum frame and display technology to improve long-term durability. The company will also offer a one-time 50% discount on display repair costs should one eventually be needed. At its thinnest point, the TriFold measures 3.9 millimeters (0.15 inch). Inside, it contains a 5,600 milliamp-hour battery, marking the largest capacity that Samsung has used in a folding phone so far. The battery provides as much as 17 hours of consecutive video playback with the TriFold display fully open. However, in specifications shared with Bloomberg, the company didn't say how long it expects the battery to last with typical usage. Read more of this story at Slashdot.

  • 'We Built a Database of 290,000 English Medieval Soldiers'
    by BeauHD on 02/12/2025 at 3:30 am

    An anonymous reader quotes a report from the Conversation, written by authors Adrian R. Bell, Anne Curry, and Jason Sadler: When you picture medieval warfare, you might think of epic battles and famous monarchs. But what about the everyday soldiers who actually filled the ranks? Until recently, their stories were scattered across handwritten manuscripts in Latin or French and difficult to decipher. Now, our online database makes it possible for anyone to discover who they were and how they lived, fought and travelled. To shed light on the foundations of our armed services -- one of England's oldest professions -- we launched the Medieval Soldier Database in 2009. Today, it's the largest searchable online database of medieval nominal data in the world. It contains military service records giving names of soldiers paid by the English Crown. It covers the period from 1369 to 1453 and many different war zones. We created the database to challenge assumptions about the lack of professionalism of soldiers during the hundred years war and to show what their careers were really like. In response to the high interest from historians and the public (the database has 75,000 visitors per month), the resource has recently been updated. It is now sustainably hosted by GeoData, a University of Southampton research institute. We have recently added new records, taking the dataset back to the late 1350s, meaning it now contains almost 290,000 entries. [...] We hope the database will continue to grow and go on providing answers to questions about our shared military heritage. We are sure that it will unlock many previously untold stories of soldier ancestors. Read more of this story at Slashdot.

  • Swiss Illegal Cryptocurrency Mixing Service Shut Down
    by BeauHD on 02/12/2025 at 1:25 am

    Longtime Slashdot reader krouic shares a report from Europol: From November 24-28, 2025, Europol supported an action week conducted by law enforcement authorities from Switzerland and Germany in Zurich, Switzerland. The operation focused on taking down the illegal cryptocurrency mixing service Cryptomixer, which is suspected of facilitating cybercrime and money laundering. Three servers were seized in Switzerland, along with the cryptomixer.io domain. The operation resulted in the confiscation of over 12 terabytes of data and more than EUR 25 million worth of Bitcoin. After the illegal service was taken over and shut down, law enforcement placed a seizure banner on the website. Authorities allege that the mixing service laundered over 1.3 billion euros in bitcoin since 2016. Read more of this story at Slashdot.

  • Smartphones At Age 12 Linked To Worse Health
    by BeauHD on 02/12/2025 at 12:45 am

    A new study from the University of Pennsylvania finds that preteens who own smartphones by age 12 have significantly higher odds of depression, obesity, and poor sleep compared to their peers. Axios reports: Kids who owned a smartphone at age 12 were found to have about 31% higher odds of depression, 40% higher odds of obesity and 62% higher odds of insufficient sleep than their peers who didn't have one. The researchers analyzed data from the National Institutes of Health-supported Adolescent Brain Cognitive Development Study assessments conducted between 2016 and 2022. The study included responses from 10,588 youths. Kids who had smartphones were more likely to be female, Black or Hispanic, and from lower-income households. The study has been published in the journal Pediatrics. Read more of this story at Slashdot.

  • Apple AI Chief Retiring After Siri Failure
    by BeauHD on 02/12/2025 at 12:23 am

    Apple's longtime AI chief John Giannandrea is retiring, with former Microsoft and Google AI leader Amar Subramanya stepping in to take over. MacRumors notes the retirement comes after the company's repeated delays in delivering its revamped Siri and internal turmoil that led to an AI team exodus. From the report: Giannandrea will serve as an advisor between now and 2026, with former Microsoft AI researcher Amar Subramanya set to take over as vice president of AI. Subramanya will report to Apple engineering chief Craig Federighi, and will lead Apple Foundation Models, ML research, and AI Safety and Evaluation. Subramanya was previously corporate vice president of AI at Microsoft, and before that, he spent 16 years at Google. He was head of engineering for Google's Gemini Assistant, and Apple says that he has "deep expertise" in both AI and ML research that will be important to "Apple's ongoing innovation and future Apple Intelligence features." Some of the teams that Giannandrea oversaw will move to Sabih Khan and Eddy Cue, such as AI Infrastructure and Search and Knowledge. Khan is Apple's new Chief Operating Officer who took over for Jeff Williams earlier this year. Cue has long overseen Apple services. [...] Apple said that it is "poised to accelerate its work in delivering intelligent, trusted, and profoundly personal experiences" with the new AI team. "We are thankful for the role John played in building and advancing our AI work, helping Apple continue to innovate and enrich the lives of our users," said Apple CEO Tim Cook in a statement. "AI has long been central to Apple's strategy, and we are pleased to welcome Amar to Craig's leadership team and to bring his extraordinary AI expertise to Apple. In addition to growing his leadership team and AI responsibilities with Amar's joining, Craig has been instrumental in driving our AI efforts, including overseeing our work to bring a more personalized Siri to users next year."
