  • Nearly 5 Million Accounts Removed Under Australia's New Social Media Ban
    by BeauHD on 17/01/2026 at 1:00 pm

    An anonymous reader quotes a report from the New York Times: Nearly five million social media accounts belonging to Australian teenagers have been deactivated or removed, a month after a landmark law barring those younger than 16 from using the services took effect, the government said on Thursday. The announcement was the first reported metric reflecting the rollout of the law, which is being closely watched by several other countries weighing whether the regulation can be a blueprint for protecting children from the harms of social media, or a cautionary tale highlighting the challenges of such attempts. The law required 10 social media platforms, including Instagram, Facebook, Snapchat and Reddit, to prevent users under 16 from accessing their services. Under the law, which came into force in December, failure by the companies to take "reasonable steps" to remove underage users could lead to fines of up to 49.5 million Australian dollars, about $33 million. [...] The number of removed accounts offered only a limited picture of the ban's impact. Many teenagers have said in the weeks since the law took effect that they were able to get around the ban by lying about their age, or that they could easily bypass verification systems. The regulator tasked with enforcing and tracking the law, the eSafety Commissioner, did not release a detailed breakdown beyond announcing that the companies had "removed access" to about 4.7 million accounts belonging to children under 16. Meta, the parent company of Instagram and Facebook, said this week that it had removed almost 550,000 accounts of users younger than 16 before the ban came into effect. "Change doesn't happen overnight," said Prime Minister Anthony Albanese. "But these early signs show it's important we've acted to make this change." Read more of this story at Slashdot.

  • Supreme Court May Block Thousands of Lawsuits Over Monsanto's Weed Killer
    by BeauHD on 17/01/2026 at 10:00 am

    The U.S. Supreme Court will hear Monsanto's argument that federal pesticide law should shield it and parent company Bayer from tens of thousands of state lawsuits over Roundup since the Environmental Protection Agency has not required a cancer warning label. The case could determine whether federal rules preempt state failure-to-warn claims without deciding whether glyphosate causes cancer. The Los Angeles Times reports: Some studies have found it is a likely carcinogen, and others concluded it does not pose a true cancer risk for humans. However, the court may free Monsanto and Bayer, its parent company, from legal claims from more than 100,000 plaintiffs who sued over their cancer diagnosis. The legal dispute involves whether the federal regulatory laws shield the company from being sued under state law for failing to warn consumers. [...] "EPA has repeatedly determined that glyphosate, the world's most widely used herbicide, does not cause cancer. EPA has consistently reached that conclusion after studying the extensive body of science on glyphosate for over five decades," the company told the court in its appeal. They said the EPA not only refused to add a cancer warning label to products with Roundup, but said it would be "misbranded" with such a warning. Nonetheless, the "premise of this lawsuit, and the thousands like it, is that Missouri law requires Monsanto to include the precise warning that EPA rejects," they said. On Friday, the court said in a brief order that it would decide "whether the Federal Insecticide, Fungicide, and Rodenticide Act preempts a label-based failure-to-warn claim where EPA has not required the warning." The court is likely to hear arguments in the case of Monsanto vs. Durnell in April and issue a ruling by late June. Read more of this story at Slashdot.

  • Biggest Offshore Wind Project In US To Resume Construction
    by BeauHD on 17/01/2026 at 7:00 am

    A federal judge has temporarily lifted the Trump administration's suspension of the Coastal Virginia Offshore Wind, allowing construction on the largest offshore wind project in the U.S. to resume. CNBC reports: Judge Jamar Walker of the U.S. District Court for the Eastern District of Virginia granted Dominion's request for a preliminary injunction Friday. Dominion called the Trump suspension "arbitrary and illegal" in its lawsuit. "Our team will now focus on safely restarting work to ensure CVOW begins delivery of critical energy in just weeks," a Dominion spokesperson told CNBC in a statement Friday. "While our legal challenge proceeds, we will continue seeking a durable resolution of this matter through cooperation with the federal government," the spokesperson said. Dominion said in December that "stopping CVOW for any length of time will threaten grid reliability for some of the nation's most important war fighting, AI and civilian assets." Coastal Virginia Offshore Wind is a 176-turbine project that would provide enough power for more than 600,000 homes, according to Dominion. It is scheduled to start dispatching power by the end of the first quarter of 2026. In December, the Trump administration paused the leases on all five offshore wind sites currently under construction in the U.S., blaming the decisions on a classified report from the Department of Defense.

  • Pesticides May Drastically Shorten Fish Lifespans, Study Finds
    by BeauHD on 17/01/2026 at 3:30 am

    An anonymous reader quotes a report from the Guardian: Even low levels of common agricultural pesticides can stunt the long-term lifespan of fish, according to research led by Jason Rohr, a biologist at the University of Notre Dame in Indiana. Signs of aging accelerated when fish were exposed to the chemicals, according to the study, published in Science, which could have implications for other organisms. [...] The research found that fish from pesticide-affected lakes showed shortened telomeres, the caps at the end of chromosomes that are known as the biological clock for aging. When they shorten, it is a sign of cellular aging and a decline in the body's regenerative capacity. The lake populations consisted of younger fish, indicating that the pesticides contributed to shortened lives. Laboratory experiments confirmed the findings and showed chronic low-dose exposure reduced fish survival and degraded telomeres. These effects were not seen with acute high-dose exposure. Chemical analysis showed chlorpyrifos, which is banned in the UK and the EU but used in the US and China, was the only compound found in the fish tissues that was consistently associated with signs of aging. These included shortened telomeres and lipofuscin deposition -- a buildup of insoluble proteins often described as cellular "junk". The worrying aging effects occurred at concentrations below current US freshwater safety standards, Rohr said, suggesting the effects of chemicals and pesticides could be occurring at low levels over the long term. While short-term exposure to high doses did not appear to cause these aging issues -- though it did cause high toxicity and death in fish -- the researchers concluded that it was long-term exposure to low doses that drove the changes. The scientists added that reduced lifespan was particularly problematic because older fish often contribute disproportionately to reproduction, genetic diversity and population stability.

  • Judge Orders Anna's Archive To Delete Scraped Data
    by BeauHD on 17/01/2026 at 2:02 am

    Anna's Archive has been hit with a U.S. federal court default judgment and permanent injunction over its scraping and distribution of OCLC's WorldCat data, which occurred more than two years ago. According to the ruling, the shadow library must delete all copies of its WorldCat data and stop scraping, using, storing, or distributing the data. "It is expected that OCLC will use the injunction to motivate third-party intermediaries to take action against Anna's Archive," reports TorrentFreak. From the report: Yesterday, a federal court in Ohio issued a default judgment and permanent injunction against the site's unidentified operator(s). This order was requested by OCLC, which owns the proprietary WorldCat database that was scraped and published by Anna's Archive more than two years ago. OCLC initially demanded millions of dollars in damages but eventually dropped this request, focusing on taking the site down through an injunction that would also apply to intermediaries. "Anna's Archive's flagrantly illegal actions have damaged and continue to irreparably damage OCLC. As such, issuance of a permanent injunction is necessary to stop any further harm to OCLC," the request read. This pivot makes sense since Anna's Archive did not respond to the lawsuit and would likely ignore all payment demands too. However, with the right type of court order, third-party services such as hosting companies and domain registrars might come along. The permanent injunction, issued by U.S. District Court Judge Michael Watson yesterday, does not mention any third-party services by name. However, it is directed at all parties that are "in active concert and participation with" Anna's Archive. Specifically, the site's operator and these third parties are prohibited from scraping WorldCat data, storing or distributing the data on Anna's Archive websites, and encouraging others to store, use or share this data. Additionally, the site has to delete all WorldCat data, which also includes all torrents. Judge Watson denied the default judgment for 'unjust enrichment' and 'tortious interference.' However, he granted the order based on the 'trespass to chattels' and 'breach of contract' claims. The latter is particularly noteworthy, as the judge ruled that because Anna's Archive is a 'sophisticated party' that scraped the site daily, it had constructive notice of the terms and entered into a 'browsewrap' agreement simply by using the service. While these nuances are important for legal experts, the result for Anna's Archive is that it lost. And while there are no monetary damages, the permanent injunction can certainly have an impact.

  • Patch Tuesday Update Makes Windows PCs Refuse To Shut Down
    by BeauHD on 17/01/2026 at 1:25 am

    A recent Microsoft Patch Tuesday update has introduced a bug in Windows 11 23H2 that causes some PCs to refuse to shut down or hibernate, "no matter how many times you try," reports The Register. From the report: In a notice on its Windows release health dashboard, Microsoft confirmed that some PCs running Windows 11 23H2 might fail to power down properly after installing the latest security updates. Instead of slipping into shutdown or hibernation, affected machines stay stubbornly awake, draining batteries and ignoring shutdown like they have a mind of their own and don't want to experience temporary non-existence. The bug appears to be tied to Secure Launch, a security feature that uses virtualization-based protections to ensure only trusted components load during boot. On systems with Secure Launch enabled, attempts to shut down, restart, or hibernate after applying the January patches may fail to complete. From the user's perspective, everything looks normal -- until the PC keeps running anyway, refusing to be denied life. Microsoft says that entering the command "shutdown /s /t 0" at the command prompt will, in fact, force your PC to turn off, whether it wants to or not. "Until this issue is resolved, please ensure you save all your work, and shut down when you are done working on your device to avoid the device running out of power instead of hibernating," Microsoft said.
