  • 'Knockoff' Browser Extension Hides Sketchy Brands On Amazon
    by BeauHD on 08/07/2026 at 6:00 pm

    alternative_right shares a report from 404 Media: A software developer made a Chrome and Firefox extension called Knockoff that automatically hides, grays out, or filters products from sketchy brands on Amazon, which highlights just how many shady brands are on the platform and how commonly they show up on searches for basic items. In just a few minutes of using the extension, Knockoff dimmed product listings for screwdrivers made by "SUNHZMCKP," spoons made by "SACATR," and a lamp made by "ROTTOGOON." In a tweet announcing the extension, developer Josh Pigford wrote "Sorry to brands like WNPETHOME, EHEYCIGA, YXYL, LU&MN, JOYIN, TOMY, GODONLIF, YOOJEE, LINGTENG, LANEIGE, VISCOO, BIODANCE, COOFANDY, BALENNZ, TOSY, and LUENX." The extension can also hide all sponsored product listings. The extension quickly went viral as a much-needed filter for people who still use Amazon and, for those who don't use Amazon because of its horrendous labor practices and other concerns, it is evidence of what an incredible wasteland the platform has become.

  • Apple Loses EU Fight Over App Store Gatekeeper Label
    by BeauHD on 08/07/2026 at 5:00 pm

    Europe's General Court dismissed Apple's challenge to the EU's designation of its App Stores and iOS as "gatekeepers" under the Digital Markets Act. The ruling means Apple remains subject to DMA obligations requiring it to allow alternative app stores, support interoperability with rival services, and avoid favoring its own services over competitors. MacRumors reports: Apple took its case to Luxembourg's General Court in 2024 after the European Commission designated its five App Stores -- on the iPhone, iPad, Mac, Apple TV, and Apple Watch -- as a single core platform service under the Digital Markets Act (DMA), a label that brings with it a set of strict obligations. Designated "gatekeepers" are prohibited from favoring their own services over those of rivals, and are prevented from combining personal data across different services. They also have to give users the option to use alternative app stores. Apple also challenged the EU's designation of iOS as a gateway platform, a status that requires the operating system allows rival services to interoperate with it. The company also disputed the classification of iMessage as a number-independent interpersonal communications service, or NIICS, which would subject the app to EU telecoms rules. But the General Court said Apple's actions regarding the iMessage service are inadmissible. Read more of this story at Slashdot.

  • Mysterious Spheres Found In Australia Are Likely Space Debris
    by BeauHD on 08/07/2026 at 3:00 pm

    An anonymous reader quotes a report from the New York Times: An Australian beach community was confused -- and later delighted -- by the discovery of six metallic-looking spheres that washed ashore last week. The mystery, and the ensuing attention, prompted a bunch of alien jokes from local residents and businesses. But Australia's space agency put the speculation to rest on Monday, saying that the spheres appeared to be rocket debris that had recently re-entered the atmosphere from orbit. The objects were found on Forrest Beach in the northeastern state of Queensland over the weekend, the state's fire department said. Residents described them as being about twice the size of a basketball. "The recovered objects appear to be pressure vessels from a space launch vehicle," the Australian Space Agency said in a statement, adding that they were "consistent with debris from a foreign rocket body." The agency said that it had identified the likely source of the objects, without providing further details, and was working with international authorities to confirm the vehicle from which the debris originated.

  • Superconducting Thruster Harnesses Earth's Magnetic Field In First Orbital Test
    by BeauHD on 08/07/2026 at 11:00 am

    New Zealand startup Zenno Astronautics has completed the first orbital test of its "Supertorquer," a shoebox-sized superconducting magnet system that uses solar power and Earth's magnetic field to help control a satellite without fuel. The company says the technology could eventually support fuel-free satellite maneuvers, docking, deep-space trajectory changes, and even magnetic radiation shielding for astronauts. Space Magazine reports: The tests began shortly after Mira's launch in November last year aboard the SpaceX Transporter 12 mission and saw the shoebox-size device perform with flying colors, Zenno Astronautics CEO and founder Max Arshavsky, told Space.com. "It's a technology that allows a spacecraft to not tumble violently in space and point in the right direction," Arshavsky said. "The unit has multiple super-conducting magnets that are positioned in different axes. When we power up the magnets, they generate a magnetic field, which interacts with Earth's magnetic field, and because we can control the magnetic field on the satellite, we can control the way in which it turns with respect to Earth." Superconducting magnets are made of coils of superconducting wire that have zero electrical resistance and can therefore conduct much larger currents than normal wires. That larger current translates into a greater magnetic force. There is, however, a catch: Superconducting materials need to be cooled to extremely low temperatures to gain their wonder properties. [...] The unit housing the superconducting magnets is wrapped in layers of insulation and fitted with a heat pump that removes all the excess heat from the system. Every time the satellite needs a push, the superconducting coils power up, drawing energy from a battery charged by the satellite's solar panels. "It's converting solar energy straight into useful work," Arshavsky said. "Energy is the one thing that is abundant in space, and you can use it to energize the magnet to create a magnetic acceleration device. It gives you acceleration without fuel." In the future, Zenno Astronautics plans to launch larger systems that could enable spacecraft to dock in space or conduct close proximity operations using just the power of their solar-powered superconducting magnets. Arshavsky envisions powerful magnets that could, in the future, propel spacecraft on missions to the moon and Mars using only solar power. Read more of this story at Slashdot.

  • Japan Releases Snowman-Like Asteroid Image After Flyby
    by BeauHD on 08/07/2026 at 7:00 am

    Japan's Hayabusa2 probe captured rare close-up images of near-Earth asteroid Torifune, revealing a snowman-like shape made of two joined lobes. Phys.org reports: The fridge-sized Hayabusa2 skimmed asteroid Torifune on Sunday in a mission that demonstrated the ability to deflect a potentially dangerous space rock away from Earth. A new image released by the Japan Aerospace Exploration Agency (JAXA) on Monday could aid such efforts, as researchers say near-Earth asteroids vary in their size, shape and surface characteristics. "The moment I actually saw this image and the scientific data -- it really gave me goosebumps," JAXA scientist Yuya Mimasu told reporters, adding the asteroid "personally looked like a snowman." The black-and-white image, captured by a telescopic camera, showed what appeared to be two round objects joined together. "You can actually see the rocks... I really hadn't expected to be able to take a photo like this, so I'm absolutely over the moon," he said. [...] Moving at a speed of more than 18,000 kilometers (11,185 miles) per hour, the probe was due to fly within 800 meters (2,625 feet) of the asteroid, but JAXA said it would analyze the distance later. If confirmed, the mission would be one of the closest flybys of a near-Earth asteroid ever. JAXA also said Monday it succeeded in acquiring data from three other devices that can measure the distance from the asteroid and examine the existence of water. Read more of this story at Slashdot.
