  • 'Super Mario Galaxy Movie' and 'Project Hail Mary' Combine for Best Box Office in 7 Years
    by EditorDavid on 12/04/2026 at 8:13 pm

    The Super Mario Galaxy Movie "is officially the year's highest-grossing film to date with $629 million at the global box office," reports Variety — and it will likely earn over $1 billion. Project Hail Mary now becomes the year's second highest-grossing movie, with four-week ticket sales over $510, notes The Hollywood Reporter: The two films have helped propel year-to-date revenue to $2.113 billion — the best showing for the first part of the year since before the pandemic in 2019 ($2.619 billion), according to Comscore. And revenue is running 25% ahead of the same corridor last year. Some context from ScreenRant: Even though The Super Mario Galaxy Movie reviews were largely negative, earning it a disappointing 43% score from critics on Rotten Tomatoes, audiences gave it a far superior score of 89% from audiences, making it Verified Hot on the platform's Popcornmeter. This indicates that the movie should continue to climb up the global box office chart thanks to strong word of mouth, even as it trails consistently behind the original 2023 movie in terms of commercial performance. Canadian astronaut Jeremy Hansen called Project Hail Mary "an inspirational example.. We all thought that movie was really uplifting and inspiring." Before the Artemis astronauts launched their mission, Space.com points out "they were treated to a viewing of Amazon MGM Studios' Project Hail Maryto bolster their spirits ahead of their monumental 10-day lunar voyage. " Marking the occasion and providing encouraging words to the three American astronauts and one Canadian astronaut, Ryan Gosling recorded a brief encouraging video for the moon-bound foursome. Today NPR took a spoiler-filled look at the science in the film, asking: Would it be possible for humans to travel to a place as far away as the Tau Ceti star system? It's not possible right now, says Lisa Carnell, division director for NASA'S Biological and Physical Sciences Division. "I don't think we are fully prepared to send humans to Mars, let alone light years away," she says. Given the leaps in technology that humanity has made in just the past century, however, she didn't want to rule it out.... "I believe it's possible [one day]"... The hypothetical study of how humans and extraterrestrials might communicate is a real scientific field, called xenolinguistics, that includes researchers from linguistics, animal communication, and anthropology. Martin Hilpert, a professor of linguistics at the University of Neuchâtel in Switzerland, says the film "gets a lot of things right" for how such an encounter might occur, though it also employs a lot of "happy coincidences" too.

  • Hisense's New Backlit RGB LED TV 'a Shot Against OLED's Bow', and Includes a DP Port
    by EditorDavid on 12/04/2026 at 6:55 pm

    "RGB LED TVs have been the talk of the TV world this year," argues The Verge, with models coming from all the manufacturers." And the first one of 2026 is here — the UR9 from China's Hisense — "the first look at the viability of the new backlight technology outside of demo rooms." They call it "a step above the traditional mini-LED TVs of years past." and "a great first shot against OLED's bow." HDR is colorful and accurate, it has great brightness, and it is capable of showing colors beyond the P3 color space for movies and TV shows that have wider color. But at $3,500, the 65-inch model I reviewed is priced comparably to high-end OLEDs from LG and Samsung, which is tough competition... One of the touted benefits of RGB LED TVs is their ability to achieve 100 percent of the BT.2020 color space... [But] even if a TV is capable of extending beyond P3 and into BT.2020 colors (which the UR9 absolutely is), with most movies and TV shows it doesn't matter. It's also a bit of a chicken-or-the-egg situation — we need TVs that can accurately display BT.2020 before the color space is fully adopted by TV and movie creators, but if there's no content, why get a BT.2020 TV? BGR points out this new mini LED TV also "includes a DisplayPort (DP) connection alongside HDMI." "Well, technically, it's a USB-C port that delivers full DisplayPort functionality, but it's labeled as DisplayPort." The TV also has three HDMI 2.1 ports, making it a great choice for game consoles and PCs. And while HDMI 2.1 supports 4K/120Hz, the Hisense UR9S will deliver 4K/170Hz or 4K/180Hz visuals [a higher refresh rate] when connected to a gaming PC via DisplayPort. Better yet, the TV is AMD FreeSync-compatible, and Hisense plans on adding Dolby Vision 2 HDR in future firmware. The Hisense UR9S will be available in four sizes: 65, 75, 85, and 100 inches. It's worth mentioning that the two largest sizes will max out at 180Hz for the refresh rate, while the 65 and 75-inch screens come in at 170Hz. This is exciting news for serious gamers looking for the best gaming TVs and a huge step forward in the evolution of panel tech. RGB Mini LED TVs were showcased by a handful of manufacturers at CES 2026, including Samsung, Sony, and LG; so Hisense will certainly have some competition. Read more of this story at Slashdot.

  • Botched IT Upgrade Ended Liquor Sales for the Entire State of Mississippi
    by EditorDavid on 12/04/2026 at 5:34 pm

    Mississippi has one warehouse — run by a contractor — that sells all the liquor for the entire state of 2.9 million people. "If a restaurant or store anywhere in Mississippi wanted a bottle of Jim Beam, they had to order it from the wholesale warehouse," reports the Washington Post. But then Mississippi's warehouse-managing contractor implemented a new computer system that wasn't compatible with the state's delivery system (like they'd promised it would be back in 2023). And then things got even worse... "The problem, business owners allege, is that the company tore out the conveyor belts but didn't hire humans to replace them." In February a state Revenue Department commissioner told lawmakers the state was hiring temporary replacement workers, but in the five weeks through March 29th they'd only managed to reduce "pending" orders by 21.7%, from 218,851 down to 171,190, according to stats from Mississippi Today. At least four Mississippi businesses are now suing the warehouse operator "claiming breach of contract and harm to their business." So what's it like in a state suddenly running dry? The Washington Post reports: Willie the one-eyed skeleton is dressed for Cinco de Mayo, but the liquor store where Willie sits ran out of Jose Cuervo months ago. Arrow Wine and Spirits is also out of Tito's and Burnett's vodka, Franzia boxed wine, Jack Daniels, and every kind of premixed margarita... Restaurants in Jackson had no wine on Valentine's Day, and bars on the Gulf Coast ran dry before Mardi Gras. At least five liquor shops have closed, and if cheap pints don't hit the corner stores soon, many of them will, too... [A]s both the state and its businesses lose millions in revenue, many say they see no real end to the crisis. Nearly 174,000 cases of alcohol are sitting in a warehouse north of Jackson, but no one seems to know how to get them out the door... Even the shops that have received deliveries say they often get the wrong thing — Jell-O shots, for instance, that should have been small-batch Norwegian gin... At Willie the one-eyed skeleton's liquor store they'd previously made 300 to 400 sales a day, according to the article, but last week had 34 customers. And Mississippi is one of 17 U.S. states requiring liquor stores to buy their liquor from distribution centers controlled by the state's Department of Revenue... Mississippi Today points out that while some want the state to finally privatize liquor distribution, "The state collects around $120 million a year in taxes on alcohol." Plus the state has already authorized "borrowing $95 million to construct a new warehouse, set to begin operations in 2027..." Thanks to Slashdot reader jrnvk for sharing the news.

  • Neuroscientist' AI-Powered Startup AIms To Transform Human Cognition With Perfect, Infinite Memory
    by EditorDavid on 12/04/2026 at 4:34 pm

    Bloomberg describes him as a "former Harvard Medical School professor whose research has focused on the intersection of AI and neuroscience." "For the past 20 years, I studied how the human brain stores and retrieves memories," Kreiman writes on LinkedIn. And now "My co-founder Spandan Madan and I built a new algorithm to endow humans with perfect and infinite memory." Engramme connects to your **memorome**, i.e., entire digital life. Large Memory Models work in the same way that your brain encodes and retrieves information. Then memories are recalled automatically — no searching, no prompting, no hallucinations. [The startup's web site promises "omniscient AI to augment human cognition."] We have built the memory layer for EVERY app. Read our manifesto about augmenting human cognition. ["We are not just building software; we are enabling a complete transformation of human cognition. When the friction disappears between needing a piece of information and recalling it, the nature of thought itself changes. This synergy between biological intuition and digital precision will be the most disruptive force in modern history, fundamentally reshaping every profession... We are dedicated to creating a world where everyone has the power to remember everything they have ever learned, seen, or felt "] Welcome to a new future where you can remember everything. This is the MEMORY SINGULARITY: after 300,000 years, this is the moment that humans stop forgetting. Bloomberg reports that the startup (spun out of a lab at Harvard) is "in talks with investors to raise about $100 million, according to people familiar with the matter."

  • DNA-Level Encryption Developed by Researchers to Protect the Secrets of Bioengineered Cells
    by EditorDavid on 12/04/2026 at 3:34 pm

    The biotech industry's engineered cells could become an $8 trillion market by 2035, notes Phys.org. But how do you keep them from being stolen? Their article notes "an uptick in the theft and smuggling of high-value biological materials, including specially engineered cells." In Science Advances, a team of U.S. researchers present a new approach to genetically securing precious biological material. They created a genetic combination lock in which the locking or encryption process scrambled the DNA of a cell so that its important instructions were non-functional and couldn't be easily read or used. The unlocking, or decryption, process involves adding a series of chemicals in a precise order over time — like entering a password — to activate recombinases, which then unscramble the DNA to their original, functional form... They created a biological keypad with nine distinct chemicals, each acting as a one-digit input. By using the same chemicals in pairs to form two-digit inputs, where two chemicals must be present simultaneously to activate a sensor, they expanded the keypad to 45 possible chemical inputs without introducing any new chemicals. They also added safety penalties — if someone tampers with the system, toxins are released — making it extremely unlikely for an unauthorized person to access the cells. "The researchers conducted an ethical hacking exercise on the test lock and found that random guessing yielded a 0.2% success rate, remarkably close to the theoretical target of 0.1%."

  • Greg Kroah-Hartman Tests New 'Clanker T1000' Fuzzing Tool for Linux Patches
    by EditorDavid on 12/04/2026 at 2:34 pm

    The word clanker — a disparaging term for AI and robots — "has made its way into the Linux kernel," reports the blog It's FOSS "thanks to Greg Kroah-Hartman, the Linux stable kernel maintainer and the closest thing the project has to a second-in-command." He's been quietly running what looks like an AI-assisted fuzzing tool on the kernel that lives in a branch called "clanker" on his working kernel tree. It began with the ksmbd and SMB code. Kroah-Hartman filed a three-patch series after running his new tooling against it, describing the motivation quite simply. ["They pass my very limited testing here," he wrote, "but please don't trust them at all and verify that I'm not just making this all up before accepting them."] Kroah-Hartman picked that code because it was easy to set up and test locally with virtual machines. "Beyond those initial SMB/KSMBD patches, there have been a flow of other Linux kernel patches touching USB, HID, F2FS, LoongArch, WiFi, LEDs, and more," Phoronix wrote Tuesday, "that were done by Greg Kroah-Hartman in the past 48 hours.... Those patches in the "Clanker" branch all note as part of the Git tag: "Assisted-by: gregkh_clanker_t1000" The T1000 presumably in reference to the Terminator T-1000. It's FOSS emphasizes that "What Kroah-Hartman appears to be doing here is not having AI write kernel code. The fuzzer surfaces potential bugs; a human with decades of kernel experience reviews them, writes the actual fixes, and takes responsibility for what gets submitted." Linus has been thinking about this too. Speaking at Open Source Summit Japan last year, Linus Torvalds said the upcoming Linux Kernel Maintainer Summit will address "expanding our tooling and our policies when it comes to using AI for tooling." He also mentioned running an internal AI experiment where the tool reviewed a merge he had objected to. The AI not only agreed with his objections but found additional issues to fix. Linus called that a good sign, while asserting that he is "much less interested in AI for writing code" and more interested in AI as a tool for maintenance, patch checking, and code review.
