  • Cloudflare Pushes AI Companies To Pay For Publishers' Content
    by BeauHD on 01/07/2026 at 9:00 pm

    BrianFagioli writes: Cloudflare announced new controls that give publishers more say over how AI companies access and use their content. Beginning September 15, new Cloudflare sites will allow traditional search indexing while blocking AI training and AI agent access on ad supported pages by default. The company is also expanding its monetization efforts with a Pay-Per-Use model that aims to compensate publishers when their content contributes to AI generated answers rather than simply being crawled. Cloudflare argues that publishers should not have to choose between being discoverable online and giving away their work for free to AI systems. Read more of this story at Slashdot.

  • Scientists Made a Cell From Scratch For First Time
    by BeauHD on 01/07/2026 at 8:00 pm

    AleRunner writes: The first fully synthetic cell ("SpudCell") has been created in the Department of Genetics at the University of Minnesota. Strictly speaking, it's described as a "cell-like system constructed entirely from known chemical components that can perform a complete cell cycle." It is able to replicate, but only for approximately five generations. The key advance is that the cell is "built entirely bottom-up from individually purified, non-living components," although it still contains material from E. coli bacteria. "PURE is a defined mixture of 36 purified enzymes from E. coli bacteria," including ribosomes, that provides the infrastructure for genetic replication. CNN has an article on the advance, including interview material with Professor Kate Adamala, who led the research. "I know the full ingredient list of the cell. I know exactly what chemicals, what molecules, at what concentrations," she said. "It is fully defined, which means we can engineer it." "Humans did not create life," notes an anonymous Slashdot reader. "Researchers call it a constructed cell, not 'life created in the lab' but a 'genuine milestone on the road toward that question.' It lacks full autonomy (needs feeding, no independent evolution)." Special thanks to Slashdot readers kemosabi and AleRunner for submitting the story and additional sources, including reports from The New York Times and The Guardian, as well as information from the University of Minnesota Twin Cities.

  • Reddit Will Require You To Log In To Use Old Reddit
    by BeauHD on 01/07/2026 at 7:00 pm

    An anonymous reader quotes a report from Ars Technica: Reddit will start requiring people to be logged into Reddit to use old.reddit.com. The new requirement will take effect "over the next month," a Reddit employee going by the username boat-botany announced on the social media platform today. The person claimed that the change is part of an ongoing effort to "tighten how automated systems access Reddit." The Reddit employee wrote: "Old Reddit's logged-out experience is a significant source of abusive scraping and automated traffic on the platform. It's also an important interface for many long-time mods and Redditors. To strike the right balance between preserving your access to Old Reddit while preventing abusive scraping and automated traffic, over the next month we will start requiring everyone to log in." In a follow-up comment, boat-botany defined abusive behavior as that which violates Reddit's rule prohibiting activity that interferes with the platform's "normal use" or that "create[s] programs or applications" that break Reddit's (controversial) API rules. "By logging in, we get a lot more signal that allows us to detect whether an account is breaking the rules, and then we can block that traffic or enforce those accounts," boat-botany said. Asked why boat-botany scrapes New Reddit less frequently than Old Reddit, the Reddit employee pointed to another commenter's explanation. "[T]he shape of malicious traffic is always changing," the user, Nestramutat, wrote. "It's going to be a constant cat and mouse game[.] As you ban one method, a new one gets developed. It's easy to see abusive traffic in hindsight, but it's harder to pre-emptively block it. Given that they're claiming Old Reddit doesn't have the modern security stack, this is likely proving to be an even greater challenge." Nestramutat said that the login requirement will add a barrier against threat actors. "You're also now attaching an account ID to every malicious request, plus account creation is only available on New Reddit (with the enhanced security stack)." As for how long Old Reddit will exist, boat-botany left the door open for its retirement. "We can't promise it will be around forever, but [Reddit CEO Steve Huffman] himself has said we'll keep supporting it while folks are still using it," boat-botany wrote. "That said, it doesn't have the same modern security tech stack reddit.com has, so we need to tighten security on old reddit to keep it viable." Read more of this story at Slashdot.

  • Sony PlayStation Will Stop Releasing Games On Discs In 2028
    by BeauHD on 01/07/2026 at 6:00 pm

    Longtime Slashdot reader AmiMoJo shares a report from the BBC: New PlayStation games will no longer be released on discs from January 2028, the gaming giant has announced. Sony said in a blog post new games would still be able to be bought in shops, but they would come with a digital code. It comes just days after Rockstar announced the hotly-anticipated Grand Theft Auto VI would similarly launch without a physical disc. It marks a significant moment for the gaming industry, which has in recent years begun to rely more and more on digital distribution. Sony said the move came "as consumer preferences and the broader entertainment industry continue to shift away from physical discs to digital." "This is a natural direction for Sony Interactive Entertainment to adapt to consumer trends as the general preference for digital media significantly outpaces physical discs," it added. [...] PlayStation said the move would have no impact on games which are already released, or would be released before January 2028. Read more of this story at Slashdot.

  • Meta Loses Bid To Dismiss US States' Claims That Facebook, Instagram Addict Children
    by BeauHD on 01/07/2026 at 5:23 pm

    A federal judge rejected Meta's bid to dismiss claims from 29 state attorneys general alleging that Facebook and Instagram were designed to addict children while concealing the harms. The judge found significant factual disputes that must be decided at trial. They also ruled that Meta failed to comply with federal parental notice and consent requirements for children under 13, "and granted summary judgement to the states on that issue," reports Reuters. From the report: In a separate statement, California Attorney General Rob Bonta called the decision a "critical win" in holding Meta accountable for fueling a mental health crisis among American children. Gonzalez Rogers also oversees related multidistrict litigation by more than 2,600 individuals, school districts and local governments over whether social media platforms such as Facebook, Instagram, Google and YouTube, Snapchat and TikTok addict children. The states said research has shown that children's use of Facebook and Instagram could lead to depression, anxiety, insomnia, interference with education and daily life, and self-harm including suicide. Meta countered that the attorneys general had no evidence it misled consumers about its platforms' alleged addictiveness, including in congressional testimony by Chief Executive Mark Zuckerberg. The Menlo Park, California-based company said this was because "social media addiction" is not an established psychiatric condition, and therefore statements that its platforms are not addictive could not be false. Meta also said it didn't violate the children's online privacy law because it directed Facebook and Instagram to a general audience, not just children under age 13. In a 38-page decision, Gonzalez Rogers found material factual disputes over whether Meta's social media platforms are addictive, whether Meta falsely denied it designed them that way, and whether it "partially" directed the platforms at children. "The AGs present a reasonable interpretation of [Meta's] statements that Facebook and Instagram are not designed in ways that cause teens to compulsively use the platforms to their detriment," the judge wrote. "To the extent plaintiffs' evidence shows that the platforms are in fact designed to do just that, a jury could reasonably find the statements were untrue to a reasonable person," she added. A trial over California, Colorado, Kentucky and New Jersey's claims against Meta is scheduled for August 18, court records show.

  • NASA Wants To Send Spare Nuclear-Powered Mars Rover To the Moon
    by BeauHD on 01/07/2026 at 4:00 pm

    An anonymous reader quotes a report from Space.com: NASA provided an Artemis update today (June 30), announcing new lunar landing contracts for its Moon Base initiative and a surprise new possible rover mission that could be headed to the moon's south pole. During the second monthly update that NASA has provided for its moon base plans, the agency named Astrobotic, Firefly Aerospace and Intuitive Machines as the providers of four robotic landers that will deliver scientific payloads to the surface of the moon, as NASA tests and expands the technologies needed for a permanent human outpost. "This is this drawing on the playbook that worked very well for NASA during the 1960s," NASA Administrator Jared Isaacman said during the livestreamed update, explaining the experiential approach to a crewed lunar return. "We didn't just jump right to Apollo 11." Isaacman also announced the potential repurposing of an engineering development model built to mirror the agency's Perseverance and Curiosity rovers on Mars. "There is another," Isaacman said, quoting Yoda's line from "Star Wars: The Empire Strikes Back." That test rover is called PROMISE, short for "Polar Rover for Observation, Mapping, and In-Situ Exploration" (though it was formerly known as Optimism). PROMISE was developed at NASA's Jet Propulsion Laboratory (JPL) in Southern California, where it has been used as a test platform for fixes or commands that engineers want to try on the ground before permanently sending them to Perseverance and Curiosity. Now, NASA wants to send PROMISE on a mission of its own. Though sending PROMISE to the moon would leave Perseverance and Curiosity -- both of which remain active on Mars -- without an Earth-based testbed, Isaacman thinks it would be worth it. "We've had years now of experience operating the two rovers on the surface of Mars, and we've got this hardware that the taxpayers have invested a lot in," he said. "So the question was posed: 'What if we send it to the moon?'" With a little refurbishment, PROMISE would help advance NASA's lunar plans, Isaacman added. Like Perseverance and Curiosity, the test rover is powered by a radioisotope thermoelectric generator (RTG), which converts heat from naturally decaying radioactive material into electricity. So it wouldn't require sunlight to operate -- a real benefit on the moon, where most locations experience long stretches of darkness. (NASA plans to build its Artemis base near the moon's south pole, which is thought to harbor an abundance of water ice and also has a relatively complex lighting environment.) The other robots currently in the works to launch on future missions to the moon, including the landers announced during today's update, are all solar powered. Through 2029, NASA hopes to launch up to 20 such missions as part of the CLPS (Commercial Lunar Payload Services) initiative to support the first phase of the agency's moon base plans, and the landers announced today will be some of the first in that lineup.
