  • 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.

  • Trump Wants Tech Companies To Foot the Bill For New Power Plants
    by BeauHD on 17/01/2026 at 12:45 am

    The Trump administration urged the largest electricity grid in the U.S. to make big tech companies pay for new power plants to support the surging electricity demand from AI and data centers. CNBC reports: Electricity prices have exploded in recent years on PJM Interconnection due in part to the data centers that tech companies are building to train and power artificial intelligence. The PJM grid serves more than 65 million people across 13 states and Washington, D.C. Its service area includes northern Virginia, the largest data center market in the world. The Trump administration and several states signed a pact that calls for tech companies to pay for new power plants built in PJM. Leading tech companies have agreed to fund $15 billion of new generation for the grid, according to an administration statement. The Trump administration and the states urged PJM to hold an emergency capacity auction to procure this power, according to the Department of Energy. PJM should also cap the amount that existing power plants can charge in the grid's capacity market to protect ratepayers, according to the administration. "We have to get out from underneath this bureaucratic system that we have in the regional grid operators and we've got to allow markets to work," said Interior Secretary Doug Burgum at the White House. "One of the ways markets can work is to have the hyperscalers actually rapidly building power." Read more of this story at Slashdot.

  • Supreme Court Hacker Posted Stolen Government Data On Instagram
    by BeauHD on 17/01/2026 at 12:02 am

    An anonymous reader quotes a report from TechCrunch: Last week, Nicholas Moore, 24, a resident of Springfield, Tennessee, pleaded guilty to repeatedly hacking into the U.S. Supreme Court's electronic document filing system. At the time, there were no details about the specifics of the hacking crimes Moore was admitting to. On Friday, a newly filled document -- first spotted by Court Watch's Seamus Hughes -- revealed more details about Moore's hacks. Per the filing, Moore hacked not only into the Supreme Court systems, but also the network of AmeriCorps, a government agency that runs stipend volunteer programs, and the systems of the Department of Veterans Affairs, which provides healthcare and welfare to military veterans. Moore accessed those systems using stolen credentials of users who were authorized to access them. Once he gained access to those victims' accounts, Moore accessed and stole their personal data and posted some online to his Instagram account: @ihackthegovernment. In the case of the Supreme Court victim, identified as GS, Moore posted their name and "current and past electronic filing records." [...] According to the court document, Moore faces a maximum sentence of one year in prison and a maximum fine of $100,000. Read more of this story at Slashdot.

  • Cloudflare Acquires Team Behind Open Source Framework Astro
    by BeauHD on 16/01/2026 at 11:20 pm

    Cloudflare has acquired the core team behind the open source JavaScript framework Astro, bringing its creators in-house while pledging to keep Astro fully open source. The New Stack reports: Astro is used by major brands like IKEA, Unilever, Visa and OpenAI to build fast, content-driven websites. Search engines prioritize fast-loading and clean pages, the Cloudflare statement noted. Websites that rely heavily on JavaScript for initial rendering often struggle to deliver the required speed, which hinders search rankings and customer conversions. Pages on Astro serve up only the code needed to display a page in a browser. That's in part because of its Island architecture, which it introduced in 2021. Astro's Islands allow developers to create "islands" of interactive client-side components, while most of the page is generated statically in HTML. Server Islands extend the same architecture to the server. Astro is also UI-agnostic, meaning that while it has its own independent engine, it allows developers to bring in components from React, Svelte, Vue and other frameworks. This makes Astro a preferred choice for building high-performance, content-driven websites optimized for speed, according to Cloudflare. "Over the past few years, we've seen an incredibly diverse range of developers and companies use Astro to build for the web," said Astro's former CTO, Fred Schott, in a post with Cloudflare senior product manager Brendan Irvine-Broque. "At Cloudflare, we use Astro, too -- for our developer docs, website, landing pages and more." They said that the acquisition will allow them to "double down" on making Astro the best framework for content-driven websites. Read more of this story at Slashdot.
