  • The Vera Rubin Telescope Begins Surveying Our Cosmos
    by BeauHD on 01/07/2026 at 12:00 pm

    The Vera C. Rubin Observatory has begun its 10-year Legacy Survey of Space and Time, using the world's largest digital camera to image the entire southern sky every few nights. The project is expected to catalog billions of stars and galaxies, track changing and transient objects, and generate an enormous dataset for studying dark matter, galaxy formation, asteroids, and unexpected cosmic phenomena. The New York Times reports: "This is the end of a 30-year wait," said Phil Marshall, the deputy director of the telescope's operations at SLAC National Accelerator Laboratory in California, in a statement to The New York Times. "It's a major milestone for us." Astronomers expect this collection of data, known as the Legacy Survey of Space and Time, to revolutionize their knowledge of our galaxy's birth, the invisible matter permeating the cosmos, what shaped the universe into the structure it has today and more. According to Dr. Marshall, the survey is designed to see everything, "even the things we don't know we're looking for yet," he said. The team behind the observatory, a joint effort funded by the U.S. Department of Energy and the National Science Foundation, unveiled several images of the cosmos that were jampacked with celestial goodness -- a peek at what the Rubin could do -- last year. Since then, scientists have been busy conducting final tests and reviews of the telescope's operations and systems. According to Bob Blum, the director of Rubin operations at the National Optical-Infrared Astronomy Research Laboratory, the team has also been hard at work ensuring that the telescope can operate reliably in different environmental conditions for the next decade.

  • DOT Announces 'Return of Supersonic Flight' For Commercial Airlines
    by BeauHD on 01/07/2026 at 9:00 am

    The FAA plans to replace its 1973 ban on civilian supersonic flight over U.S. land with a noise-based standard, potentially allowing aircraft to exceed Mach 1 as long as they stay below certain sound limits. The agency aims to finalize the rules by mid-2027, opening the door for companies such as Boom Supersonic and Spike Aerospace to operate quieter next-generation passenger jets over land. Longtime Slashdot reader schwit1 shared the notice (PDF) published Tuesday by the FAA. Forbes reports: Technological advances "will eliminate the old sonic boom," FAA Administrator Bryan Bedford said in a statement. "This means we can ultimately repeal the ban from the 1970s on supersonic flight over U.S. territory while minimizing noise impacts to residents in communities along the route and near airports." The primary reason was public opposition to loud sonic booms. In the 1960s, a plane flying faster than the speed of sound -- about 660 mph at high altitudes -- created shock waves that traveled to the ground and reached human ears as a loud gunshot-like crack or thunder-like boom. Tests during that decade, including the Oklahoma City sonic boom experiments, found repeated booms broke windows, damaged property and generated thousands of public complaints. In its 1973 ruling, the FAA stated that due to the limits of technology at that time, "a prohibition was needed to protect the public from sonic boom .... by preventing operations of a civil aircraft at a true flight Mach number greater than 1." Several years later, Air France and British Airways introduced Concorde, and were allowed to serve New York's John F. Kennedy International Airport as long as flights remained subsonic over U.S. land. Notably, "the prestigious London-New York service was the only truly profitable [Concorde] route, supported by high-powered business and celebrity travel," wrote a former British Airways network planner for Forbes in 2021. Several U.S. companies are working on a new generation of luxurious supersonic passenger aircraft with much quieter sonic booms and improved fuel efficiency. In particular, Colorado-headquartered Boom Supersonic says it has pre-orders from United Airlines, American Airlines and Japan Airlines for its Overture jets, which will carry 60-80 passengers. Atlanta-based Spike Aerospace is developing smaller Diplomat jets for up to 18 passengers. Both companies' websites tout future transatlantic flights in under four hours.

  • Trump Drops Restrictions On Anthropic's Mythos and Fable Models
    by BeauHD on 01/07/2026 at 6:00 am

    The Trump administration has lifted export restrictions that forced Anthropic to shut off public access to its Mythos and Fable models. After weeks of talks, Secretary of Commerce Howard Lutnick said Anthropic "has agreed to proactively detect and address security risks associated with the models; to work diligently with the U.S. government on protocols and standards and releases for Mythos, Fable and future models; and to inform the US government of any malicious activity." Access is set to begin returning July 1. TechCrunch reports: Anthropic had already publicly pledged to do much of this voluntarily, months before the export rule existed. That's part of why cybersecurity experts were skeptical of the restrictions in the first place. To them, the ban looked less like a security fix and more like leverage, a way for the Trump administration to punish Anthropic for its executives' public criticism of how the government, and the president's political opponents, might use the technology. Mythos was originally made available to a select group of organizations beginning in April to allay concerns about its ability to identify and exploit vulnerabilities in software, while a version called Fable was released to the public in June with additional security guardrails. However, with Asian AI companies beginning to release their own AI models approaching Mythos-level capabilities -- among them Fugu and Tulonfeng -- the US government was under pressure to ease its restrictions on Anthropic to ensure that American AI could compete globally. Last week, Lutnick cleared Mythos to be released to select customers approved by the White House. OpenAI's latest models were also released to a group of organizations approved by the Trump team, instead of the public. The Trump administration's erratic approach to AI policymaking has left companies across the industry with little clarity about what will govern future model releases. An executive order issued in June that signaled a desire to review models ahead of release was criticized by influential analysts like Dean W. Ball, who recently started a policy position at OpenAI.

  • New Florida Law Bans Local Net-Zero Emissions Policies
    by BeauHD on 01/07/2026 at 3:30 am

    An anonymous reader quotes a report from Inside Climate News: A new state law limits Florida communities' aims to offset greenhouse gas emissions that are warming the global climate and intensifying disasters such as hurricanes. Specifically, HB 1217 prohibits local governments from pursuing net-zero emissions goals. At least 10 cities and counties have implemented such policies, including Fort Lauderdale, Miami, Orlando and Leon County, where Tallahassee, the state capital, is located. But the new law will not necessarily upend these policies, said Bradley Marshall, senior attorney at Earthjustice, an advocacy group. "It's certainly meant to scare municipalities and local governments from trying to do things to further net-zero policies," he said. "Now, its exact impact and what it exactly prohibits is probably up for some debate. Things that are adjacent to it -- emissions reductions and even climate change reduction policies -- on their face will not run afoul at all of a ban on adopting a net zero policy." The measure requires local governments to submit an affidavit annually to the state Department of Revenue verifying compliance. Gov. Ron DeSantis, a Republican, signed the measure on April 22, Earth Day, and the law will take effect July 1. It states that "net zero policies, carbon taxes and assessments, and emission trading programs are detrimental to this state's energy security and economic interests and inconsistent with the energy policy and the environmental policy of this state." [...] HB 1217 also prevents local governments from purchasing items such as vehicles or appliances based on the fuels they use or production of the items. Local governments may not participate in carbon-trading programs or use public funds to support other organizations with net-zero policies. Cities and counties also may not charge a tax or fee tied with carbon emissions. "This bill is definitely part of a larger coordinated push by the political enablers of the fossil fuel industry to obstruct any tools -- legal or legislative tools -- to hold the industry accountable for its contributions to climate change," said Laura Peterson, senior analyst at the Union for Concerned Scientists, an advocacy group. "Florida is really on the front lines. So I imagine the governor is taking this step because he sees what's coming down the pike. It's not getting better. So I can only assume that this is an effort to satisfy some of the pressures that he's getting from donors and from his party to protect the industry. And he's doing it at the expense of his constituents." Read more of this story at Slashdot.

  • Amazon Blames Piracy Apps With Malware For Killing New Fire Stick Sideloading
    by BeauHD on 30/06/2026 at 11:00 pm

    Amazon says it is ending sideloading on new Fire Sticks because "apps that facilitate piracy, and other apps, can carry malware," adding that there is "a good amount of evidence" that sideloaded apps may contain unwanted code or behavior. However, the company did not provide specific examples of Fire Stick users being harmed. Ars Technica reports: Amazon has released two Fire Stick models that use its proprietary, Linux-based operating system, Vega OS. Previous Fire Sticks ran Fire OS, which is an Android fork based on the Android Open Source Project. One of the biggest differences between Vega OS and Fire OS is that the former doesn't support sideloading. [...] In a recent interview, Or Goren, editor-in-chief of Cord Busters, a UK-based streaming news outlet, noted the negative reaction to Vega being a closed OS. [Aidan Marcuss, VP of Fire TV, advertising, and Appstore] responded, per the publication, by saying that Vega OS was Amazon's opportunity to "innovate and deliver more capabilities, even on the least expensive devices." He also said that making a platform around security and privacy was "sort of utmost in my mind." The statement is somewhat ironic, considering Vega OS blocks custom launchers and other third-party apps that helped users avoid Amazon tracking and ads. Goren asked whether Amazon had evidence that sideloaded devices caused users harm. "Apps that facilitate piracy, and other apps, can carry malware," Marcuss responded. Marcuss also said that there is "a good amount of evidence that apps can carry unwanted code and behavior on them when they're sideloaded." Marcuss didn't provide specific examples of Fire Stick users being hurt by sideloaded apps. There are some potential examples, though. In 2025, Amazon claimed to blacklist (which blocked the apps from being sideloaded to Fire Sticks) four video streaming apps for malicious behavior. At the time, AFTVnews reported that two of the apps served as residential proxy providers and were considered riskware, and that the other two had APK files that were flagged by virus-scanning tools. Safari and Chrome also flagged one of the apps' official websites, the publication reported. And in 2018, a botnet that infected Android devices with cryptocurrency-mining malware appeared on some Fire Sticks, per discussion on XDA Forums. That said, Amazon also has a history of disabling apps that let users circumnavigate its home screen that Fire devices, including Fire Sticks and Fire TVs, have increasingly used for ads. Worth noting: developers can continue sideloading apps onto Vega OS devices if they register them with Amazon. Read more of this story at Slashdot.

  • Google Pulls the Plug On Tenor API, Killing GIF Pickers Around the Web
    by BeauHD on 30/06/2026 at 10:00 pm

    Google has shut down the Tenor API, breaking GIF pickers in services that still relied on it and forcing platforms such as X to migrate elsewhere. 9to5Google notes that the library itself remains available at Tenor.com and "integrations within Google products are also still active, including Gboard, Google Messages, and more." From the report: The Tenor API has been rejecting new API sign-ups in January of this year, but existing integrations remained in place. This week, though, they're shutting down, and any integrations that remain in place will stop working on July 1. The support page adds details that "any API or Ads Distribution Agreements" with Tenor will be terminated on June 30, while "current integrations" will be "fully decommissioned" as of June 30. One of the most notable examples here is Twitter/X, which has relied on Tenor for its GIF picker for years. Twitter/X Head of Product Nikita Bier confirmed that the platform has migrated elsewhere, which is why the "recently used" section was purged, and why you might notice fewer GIF options when posting. Other platforms affected include Discord, WhatsApp, and Bluesky. Read more of this story at Slashdot.
