  • Moss Spores Survive 9 Months Outside ISS
    by BeauHD on 21/11/2025 at 7:00 am

    alternative_right shares a report from Phys.org: Inspired by moss's resilience, researchers sent moss sporophytes -- reproductive structures that encase spores -- to the most extreme environment yet: space. Their results, published in the journal iScience on November 20, show that more than 80% of the spores survived nine months outside of the International Space Station (ISS) and made it back to Earth still capable of reproducing, demonstrating for the first time that an early land plant can survive long-term exposure to the elements of space. [Lead author Tomomichi Fujita of Hokkaido University and his team] subjected Physcomitrium patens, a well-studied moss commonly known as spreading earthmoss, to a simulated a space environment, including high levels of UV radiation, extreme high and low temperatures, and vacuum conditions. They tested three different structures from the moss -- protenemata, or juvenile moss; brood cells, or specialized stem cells that emerge under stress conditions; and sporophytes, or encapsulated spores -- to find out which had the best chance of surviving in space. The researchers found that UV radiation was the toughest element to survive, and the sporophytes were by far the most resilient of the three moss parts. None of the juvenile moss survived high UV levels or extreme temperatures. The brood cells had a higher rate of survival, but the encased spores exhibited ~1,000x more tolerance to UV radiation. The spores were also able to survive and germinate after being exposed to 196C for over a week, as well as after living in 55C heat for a month. Read more of this story at Slashdot.

  • Advocacy Groups Urge Parents To Avoid AI Toys This Holiday Season
    by BeauHD on 21/11/2025 at 3:30 am

    An anonymous reader quotes a report from the Associated Press: They're cute, even cuddly, and promise learning and companionship -- but artificial intelligence toys are not safe for kids, according to children's and consumer advocacy groups urging parents not to buy them during the holiday season. These toys, marketed to kids as young as 2 years old, are generally powered by AI models that have already been shown to harm children and teenagers, such as OpenAI's ChatGPT, according to an advisory published Thursday by the children's advocacy group Fairplay and signed by more than 150 organizations and individual experts such as child psychiatrists and educators. "The serious harms that AI chatbots have inflicted on children are well-documented, including fostering obsessive use, having explicit sexual conversations, and encouraging unsafe behaviors, violence against others, and self-harm," Fairplay said. AI toys, made by companies including Curio Interactive and Keyi Technologies, are often marketed as educational, but Fairplay says they can displace important creative and learning activities. They promise friendship but disrupt children's relationships and resilience, the group said. "What's different about young children is that their brains are being wired for the first time and developmentally it is natural for them to be trustful, for them to seek relationships with kind and friendly characters," said Rachel Franz, director of Fairplay's Young Children Thrive Offline Program. Because of this, she added, the trust young children are placing in these toys can exacerbate the types of harms older children are already experiencing with AI chatbots. A separate report Thursday by Common Sense Media and psychiatrists at Stanford University's medical school warned teenagers against using popular AI chatbots as therapists. Fairplay, a 25-year-old organization formerly known as the Campaign for a Commercial-Free Childhood, has been warning about AI toys for years. They just weren't as advanced as they are today. A decade ago, during an emerging fad of internet-connected toys and AI speech recognition, the group helped lead a backlash against Mattel's talking Hello Barbie doll that it said was recording and analyzing children's conversations. This time, though AI toys are mostly sold online and more popular in Asia than elsewhere, Franz said some have started to appear on store shelves in the U.S. and more could be on the way. "Everything has been released with no regulation and no research, so it gives us extra pause when all of a sudden we see more and more manufacturers, including Mattel, who recently partnered with OpenAI, potentially putting out these products," Franz said. Last week, consumer advocates at U.S. PIRG called out the trend of buying AI toys in its annual "Trouble in Toyland" report. This year, the organization tested four toys that use AI chatbots. "We found some of these toys will talk in-depth about sexually explicit topics, will offer advice on where a child can find matches or knives, act dismayed when you say you have to leave, and have limited or no parental controls," the report said.

  • Fired Techie Admits Sabotaging Ex-Employer, Causing $862K In Damage
    by BeauHD on 21/11/2025 at 2:20 am

    An Ohio IT contractor pleaded guilty to breaking into his former employer's network after being fired, impersonating another worker and using a PowerShell script to reset 2,500 passwords -- an act that locked out thousands of employees and caused more than $862,000 in damage. He faces up to 10 years in prison. The Register reports: Maxwell Schultz, 35, impersonated another contractor to gain access to the company's network after his credentials were revoked. Announcing the news, US attorney Nicholas J. Ganjei did not specify the company in question, which is typical in these malicious insider cases, although local media reported it to be Houston-based Waste Management. The attack took place on May 14, 2021, and saw Schultz use the credentials to reset approximately 2,500 passwords at the affected organization. This meant thousands of employees and contractors across the US were unable to access the company network. Schultz admitted to running a PowerShell script to reset the passwords, searching for ways to delete system logs to cover his tracks -- in some cases succeeding -- and clearing PowerShell window events, according to the Department of Justice. Prosecutors said the attack caused more than $862,000 worth of damage related to employee downtime, a disrupted customer service function, and costs related to the remediation of the intrusion. Schultz is set to be sentenced on Jan 30, 2026, and faces up to ten years in prison and a potential maximum fine of $250,000. Read more of this story at Slashdot.

  • IBM, Cisco Outline Plans For Networks of Quantum Computers By Early 2030s
    by BeauHD on 21/11/2025 at 1:40 am

    IBM and Cisco plan to link quantum computers over long distances by the early 2030s, "with the goal of demonstrating the concept is workable by the end of 2030," reports Reuters. "The move could pave the way for a quantum internet, though executives at the two companies cautioned that the networks would require technologies that do not currently exist and will have to be developed with the help of universities and federal laboratories." From the report: The challenge begins with a problem: Quantum computers like IBM's sit in massive cryogenic tanks that get so cold that atoms barely move. To get information out of them, IBM has to figure out how to transform information in stationary "qubits" -- the fundamental unit of information in a quantum computer -- into what Jay Gambetta, director of IBM Research and an IBM fellow, told Reuters are "flying" qubits that travel as microwaves. But those flying microwave qubits will have to be turned into optical signals that can travel between Cisco switches on fiber-optic cables. The technology for that transformation -- called a microwave-optical transducer -- will have to be developed with the help of groups like the Superconducting Quantum Materials and Systems Center, led by the Fermi National Accelerator Laboratory near Chicago, among others. Along the way, Cisco and IBM will also publish open-source software to weave all the parts together. Read more of this story at Slashdot.

  • Mozilla Says It's Finally Done With Two-Faced Onerep
    by BeauHD on 21/11/2025 at 1:00 am

    Mozilla is officially ending its partnership with Onerep after more than a year of controversy over the company's founder secretly running people-search and data-broker sites. Monitor Plus will be discontinued by December 2025, existing subscribers will receive prorated refunds, and Mozilla says it will focus on privacy tools it fully controls. KrebsOnSecurity reports: In a statement published Tuesday, Mozilla said it will soon discontinue Monitor Plus, which offered data broker site scans and automated personal data removal from Onerep. "We will continue to offer our free Monitor data breach service, which is integrated into Firefox's credential manager, and we are focused on integrating more of our privacy and security experiences in Firefox, including our VPN, for free," the advisory reads. Mozilla said current Monitor Plus subscribers will retain full access through the wind-down period, which ends on Dec. 17, 2025. After that, those subscribers will automatically receive a prorated refund for the unused portion of their subscription. "We explored several options to keep Monitor Plus going, but our high standards for vendors, and the realities of the data broker ecosystem made it challenging to consistently deliver the level of value and reliability we expect for our users," Mozilla statement reads.

  • Major Music Labels Strike Deals With New AI Streaming Service
    by BeauHD on 21/11/2025 at 12:20 am

    An anonymous reader quotes a report from Bloomberg: The world's largest music companies have licensed their works to a music startup called Klay, which is building a streaming service that will allow users to remake songs using artificial intelligence tools. Klay is the first music AI service to reach a deal with all three major record labels, Universal Music Group NV, Sony Music and Warner Music Group Corp., according to people familiar with the deals. Klay plans to announce its agreements in the coming days, said the people, who asked not to be identified discussing confidential plans. Klay is building a product that will offer the features of a streaming service like Spotify, amplified by AI technology that will let users remake songs in different styles. Klay has licensed the rights to thousands of hit songs so that it can train its large language model. The company has positioned itself as a friend of the industry, offering assurances that the artists and labels will have some control over how their work is used. Klay is led by music producer Ary Attie and also employs former executives from Sony Music and Google's DeepMind, an AI laboratory. Read more of this story at Slashdot.
