  • Sony's Decision To Ditch Discs Was Practically Inevitable, Data Shows
    by BeauHD on 23/07/2026 at 7:00 pm

    An anonymous reader quotes a report from Ars Technica: Many gamers have been lamenting Sony's recently announced decision to halt sales of physical game discs in 2028. However, new data revealed by Circana analyst Mat Piscatella highlights how years of stark economic trends helped lead Sony to that decision. In a social media thread Thursday morning, Piscatella shared insights into Circana's tracking data on physical game sales in the U.S. dating back to 2003. A graph of those trends shows physical sales peaking in the 12 months ending June 2009, when 297 million units were sold across the US. Those physical unit sales have been on a steady downward trajectory since then, leading to just 37 million physical units selling in the U.S. in the last 12 months. The newly revealed data follows on an earlier post from Piscatella highlighting that only seven PlayStation games had sold over 100,000 physical units so far in 2026. Today, Piscatella followed up on that stat with a graph showing how this baseline used to be common; 100 PlayStation games sold at least 100,000 physical units in 2008. The ceiling for physical PlayStation game sales isn't all that impressive these days either; Piscatella shared that the top-selling physical PlayStation game has only sold a paltry 275,000 units in the U.S. so far this year. There are some small signs of hope for the physical game market, if you squint. Piscatella noted that aggregate spending on physical video games in the U.S. was actually up 4 percent year-to-date, compared to the year before. But that small increase is a mere blip following 16 straight years of sizable declines in physical game spending in the US, reducing a peak of $11.5 billion in physical spending in 2009 to a mere $1.6 billion for the 12 months ending in May. And Piscatella attributed the recent growth in physical spending to "the Switch 2 and physical sales growth on Nintendo platforms," while other platforms (such as PlayStation) were still seeing "percentage drops from the teens to the mid 30s" in that spending.

  • In a First, Apple Maps Navigation To Be Embedded In Ford UEV Pickups
    by BeauHD on 23/07/2026 at 6:00 pm

    Ford will become the first automaker to embed Apple Maps directly into its vehicles, starting with an all-electric midsize pickup built on its new Universal Electric Vehicle platform. "The pickup -- with Ford testing preproduction models on roads now -- is expected to start at $30,000 when it comes to market in 2027," reports the Detroit Free Press. "Ford has said several other EVs off that platform will follow, including a small all-electric SUV." From the report: Ford CEO Jim Farley said the new EVs will redefine advanced technology as simple, useful, and at a price point that is attainable for most people. "We're proud to embed Apple Maps' navigation and mapping technology directly into our Universal Electric Vehicle Platform, giving customers the ultimate navigation experience alongside our Ford app, a full suite of software, and next-generation BlueCruise, all enabled by a new zonal architecture," Farley said in a statement. "Apple Maps has delivered a world-class product, and we're honored to be among the first to embed it directly into a vehicle, helping define intuitive, capable driving." In a joint statement, Apple and Ford said the integration will deliver a "beautiful and easy-to-use navigation experience powered by Apple Maps directly to the vehicle's displays. Road-level Maps information will also enable Ford's Latitude AI team to build a seamless hands-free driving experience." Ford said it will use that road information to develop its next-generation BlueCruise hands-free highway driving capability. Also, by leveraging Apple's new MapKit for Automotive SDK, Ford's UEV Platform will offer drivers turn-by-turn directions using natural language, real-time traffic information, intuitive search and routing options for the best route. The system will give drivers EV routing functionality to help drivers with the warming and cooling process of the vehicle's battery before driving or fast-charging.

  • Four Young Mathematicians Awarded the 2026 Fields Medals
    by BeauHD on 23/07/2026 at 5:00 pm

    Scientific American reports that the 2026 Fields Medals went to four mathematicians for work ranging from the theory of knots to the motion of fluid: The Fields Medals went to Hong Wang of New York University and France's Institute of Advanced Scientific Studies (IHES), Yu Deng of the University of Chicago, John Pardon of Stony Brook University and Jacob Tsimerman of the University of Toronto. In the awards' 90-year history, Wang is only the third woman to win one, after mathematicians Maryam Mirzakhani and Maryna Viazovska in 2014 and 2022, respectively. Wang and Deng represent the prizes' only Chinese-born recipients besides mathematician Shing-Tung Yau, who won a Fields Medal in 1982. Hong Wang co-proved the three-dimensional Kakeya conjecture, establishing a fundamental limit on how little space is needed to rotate a line through every possible direction. Mathematician Nets Katz called it the field's "holy grail" problem and said the achievement made her "a central figure" in the area. Yu Deng and his collaborators reconciled the microscopic and macroscopic mathematics of fluid motion, proving that equations describing chaotic molecular interactions and large-scale fluid behavior are fundamentally connected. N.Y.U. mathematician Scott Armstrong called it "a truly spectacular, singular result." John Pardon made an early breakthrough in knot theory by proving that certain sequences of knots can have arbitrarily large "distortion," a measure of how difficult they are to traverse. Princeton mathematician David Gabai said the problem had "attracted much interest among mathematicians during the previous 25 years." Jacob Tsimerman and two collaborators proved the Andre-Oort conjecture, giving mathematicians a stronger way to understand special points on complex geometric objects known as Shimura varieties. Collaborator Jonathan Pila described him as "a brilliant mathematician" known for his "brilliance and resourcefulness." Tsimerman has also advanced Hodge theory and hopes pure mathematics can help researchers better understand AI. Read more of this story at Slashdot.

  • Startup Founders Urge Trump Not to Shut Off Chinese Open Weight AI
    by BeauHD on 23/07/2026 at 4:00 pm

    Nearly 200 Silicon Valley companies, including Proton and Y Combinator, are urging the Trump administration not to block U.S. access to Chinese open-weight AI models or risk crippling the next generation of U.S. startups. Politico reports: On Wednesday, the newly-formed Little Tech Association sent letters to President Donald Trump, Commerce Secretary Howard Lutnick and others in the administration with its appeal, marking the first coordinated effort by Silicon Valley's wider influential startup community to weigh in on one of the Trump administration's most closely watched AI debates. At issue: whether Washington should restrict access to increasingly powerful open-weight -- meaning, AI models whose weights are publicly available -- AI models released by Chinese companies such as Moonshot AI and Alibaba. "American leadership requires two things: world-leading American open-weight models and continued access for U.S. builders to open models already available worldwide," the startup founders wrote in the letter (PDF) obtained by POLITICO, also sent to Office of Science and Technology Policy Director Michael Kratsios. Instead of broad prohibitions, they argue the government should adopt targeted safeguards. And they warn that banning Americans from downloading Chinese open-weight models wouldn't stop their proliferation -- but would weaken U.S. startups. "There'll be hundreds of companies that instantly die," said Suhail Doshi, founder of AI infrastructure startup Particle and a member of the association, which POLITICO first wrote about exclusively, in an interview. "It's great for Anthropic. We're all going to have to spend money on Anthropic." Last week, the Beijing-based AI company "Moonshot" released a massive new model that reset the AI race overnight, immediately vaulting into the top tier of global AI, beating Anthropic's Fable 5 and OpenAI's GPT-5.6 Sol in front-end coding tests. China's Xi Jinping also used his first appearance at China's World AI Conference to promote a vision of low-cost, broadly accessible AI and call for international cooperation rather than technological rivalry.

  • Researchers Discover First Known Transmissible Cancer In Fish
    by BeauHD on 23/07/2026 at 3:00 pm

    An anonymous reader quotes a report from CBC News: It's rare that cancerous tumors can spread from one individual to another. But a genetic study suggests that's what's happening with melanoma tumors among catfish in Quebec and the northeastern U.S. The discovery represents the first known transmissible cancer in fish and one of very few transmissible cancers ever found, reported the study published in the journal Nature on Wednesday. Julie Dragon, co-leader of the new study, noted that only three other transmissible cancers have ever been identified so far -- in Tasmanian devils, dogs and shellfish. "These conditions are incredibly rare in nature," she said. "So something has to be happening to allow this to happen." Anglers in Lake Memphremagog, which spans the border between Quebec and Vermont, first reported catching brown bullhead catfish with strange black spots and lumps in 2012. They turned out to be melanoma skin cancer tumors. (Humans can also get this kind of cancer.) Now, about a third of the brown bullheads living in the lake have them. It's not clear how sick the fish become. In some cases, the cancer spreads to other organs, such as the brain or liver. But many fish with lesions seem relatively healthy and some older fish even have them, suggesting they can live with the disease for a time. Because of the sudden appearance of the black lesions in Lake Memphremagog the year after a huge flood caused by post-tropical storm Irene, locals worried they were caused by carcinogens washed into the lake by floodwaters. Tests for carcinogens haven't been conclusive, although a study published in May found higher concentrations of seven metals, including zinc and the carcinogen arsenic, in the skin of fish with the tumors. Researchers suspect the tumors may spread among adult fish during spawning, when crowded fish rub against one another and may be punctured by their spines. "They... swim all over each other and we think it's possible that they poke each other and cells can get into other fish that way," Dragon said, though transmission has not yet been demonstrated.

  • Verisign Is Finally Bringing .web Domains To the Internet
    by BeauHD on 23/07/2026 at 11:00 am

    BrianFagioli writes: Verisign is finally bringing web domains to the internet after a decade of fighting. Verisign says the .web top-level domain has finally been delegated into the DNS root, clearing the way for public registrations later in 2026. Until now, consumers could not buy normal working .web domains, despite the extension attracting a record $135 million winning bid in 2016. The launch could make .web one of the more recognizable alternatives to .com, but Verisign already operates both .com and .net, raising questions about whether this creates real competition or simply gives the dominant registry operator another valuable extension. The decade-long fight began after a company called Nu Dot Co won the rights to operate .web in a 2016 ICANN auction with a record $135 million bid secretly funded by Verisign. Rival bidder Afilias, which was later acquired by Donuts, challenged the sale, arguing ICANN should have investigated the relationship before allowing the auction. This triggered years of complaints, reviews, and legal disputes that have ultimately now been resolved under undisclosed terms. Read more of this story at Slashdot.
