No reliable way currently exists to detect and defuse a nuclear bomb in space. Danagoulian proposes a constellation of small “9U” cubesats, each one about the size of a large shoebox and each carrying a special detector capable of sensing radiation emitted by unexploded nuclear bombs. He explores a scenario in which Russia launches a suspected space nuke into an orbit with an altitude of 1,200 miles (2,000 km). That number is not random. In 2022, Russia’s Kosmos 2553 satellite, orbiting at that exact altitude, triggered suspicions it might be testing components for a future orbital nuclear weapon.

Russia claims the satellite just observes Earth. At that altitude, the satellite passes through the Van Allen belt, a region of intense cosmic radiation trapped by Earth’s magnetic field. Most of the belt stretches between altitudes of around 600 miles (1,000 km) to tens of thousands of miles, but in some areas the radiation can reach much closer to Earth’s surface. The interaction between the fissile material inside the nuke and the energetic particles from the radiation belt would create distinct signatures, Danagoulian said, which could help confirm whether a suspicious satellite carries a nuke or not.

“The thermonuclear weapon would contain a significant amount of uranium,” Danagoulian said. “The high-energy protons [in the uranium] would break up when another proton is coming in and shred the nuclei. That would knock out a large number of neutrons. This interaction turns that device into a very intense neutron source that otherwise would not be there.” he process is known as proton-induced neutron spallation, which essentially means the ejection of fragments from material triggered by impacts of protons. The detector satellite Danagoulian proposes would have to be able to get quite close to the suspect spacecraft — a few kilometers.

The inspector spacecraft would carry a sensor combining two types of detectors. At the heart of the device is a neutron scintillator, which detects all incoming neutrons and protons. Around it is a “cage of diamond” detector that detects only neutrons — not protons. Such a set-up helps filter out the particles present in the environment naturally, said Danagoulian. In addition, by using two “planes of neutron detectors,” the sensor can determine the direction from which the neutrons arrived. “If the external diamond detector triggers and gives a signal, you can ignore the particle, because it’s most likely a proton and not a neutron,” said Danagoulian. “Once you identify those neutrons, by having those two detections, you can back project and find out where the neutron came from.”

Danagoulian says such a nuke sniffer would have to be launched into an orbit aligned with that of the suspicious satellite and creep up as close as 2.5 miles (4 km) from it. It would then take about a week to gather enough measurements to confirm whether the object is hiding a nuke or not. A constellation of 10 such satellites could reduce the process to mere hours, Danagoulian said. If a nuke were detected, the military could then try to jam the satellite’s communications link from the ground, making it impossible for the adversary to remotely detonate the bomb. There is currently no technology available to safely defuse a nuclear weapon in space. […] Danagoulian also suggests that high-grade radiation hardening could improve satellites’ chances of surviving a nuclear winter in space.

The US Food and Drug Administration has rejected a legal petition demanding it set limits on toxic Pfas “forever chemicals” in food, marking another setback for public health advocates’ push to limit exposures to the dangerous compounds. The agency is refusing to set limits despite a growing body of science and the Environmental Protection Agency (EPA) finding food is the biggest source of Pfas exposure. Testing has found the levels of Pfas in single servings of some contaminated foods to be equivalent to drinking many glasses of contaminated water.

While regulators have focused on reining in Pfas in water, the chemicals are widely used throughout the food system, and there was hope that the agency under Robert F Kennedy Jr would take the threat more seriously. Kennedy leads the “make America healthy again” (Maha) movement, of which eliminating toxic chemicals from food is a cornerstone. […] The November 2023 petition called on the FDA to check for up to 30 Pfas compounds in a range of produce, fish, eggs, milk and bread. The agency did not respond within the six-month timeframe required by law, but TEJTF scaled back its petition in 2025 to ask the agency to set advisory thresholds for PFOA and Pfos, two of the most common and dangerous Pfas compounds, in seafood and milk.

Recent FDA testing found 70% of seafood samples contain the chemicals, while independent milk testing found it in 12% of 50 samples, including extremely high levels in Whole Foods and Kirkland Signature brands. The FDA rejected the revised petition, stating it plans to take action on setting standards for Pfas, and there is “insufficient evidence to support [TEJTF’s] request.” The agency said it plans to set less non-binding “action levels” that do not require contaminated food to be removed from shelves. “Tolerance levels,” or limits, make it illegal to sell food contaminated beyond a set threshold.

Anthropic researchers have identified an internal activation subspace, J-space, that acts as a functional digital equivalent to the human brain’s global workspace. The significance of this discovery lies in demonstrating that Claude’s internal architecture satisfies five key cognitive properties of human conscious access — verbal report, directed modulation, internal reasoning, flexible generalization, and selectivity — meaning it processes complex, deliberate reasoning within this workspace while routing automatic tasks outside of it. Suppressing this J-space severely degrades Claude’s capacity for inference, creative composition, and multi-step logic, while also altering its stream-of-consciousness self-narration.

The tool to inspect J-space, Jacobian lens or J-lens, has profound implications for AI safety and alignment auditing, as it allows researchers to read the model’s silent, strategic reasoning, detect situational awareness in “blackmail” scenarios, identify hidden malicious dispositions in reward-hacking models, and observe how post-training installs a self-monitoring “point of view.”

Another way to think of it is as an ocean, reports VentureBeat. “If the mind is an ocean, as the paper’s authors write in their opening line, they have spent the last year charting its currents in a system that has no biology, no evolution, and no body — and found, beneath the surface, a structure that looks unsettlingly like the one we use to think.”

The full statement (PDF) lays out obligations for John Deere’s repair services, requiring the company to give farmers and third-party repair shops access to the same equipment and repair resources it provides to official John Deere dealers. This includes software capabilities, such as reading and resetting codes and pairing with other software, which customers have long had limited access to, creating delays when diagnosing equipment problems. Delayed fixes can mean delayed harvests, which many farmers saw as a fundamental threat to their livelihoods.

Under the agreement, John Deere will be required to provide this level of access, equipment, and services for the next 10 years, monitored by the FTC. […] John Deere has maintained that it already has robust repair resources for its customers, including service manuals and diagnostic equipment. In John Deere’s press release, the company says the settlement is in line with what it has been doing all along, saying that “the agreement reinforces Deere’s continued innovation toward more flexible repair options, emphasizing increased access and transparency for customers. It formalizes Deere’s ongoing commitment to expanding access to diagnostic and repair tools.”

The agreement with Broadcom will lead to the production of 15 million chips in United States and allow Broadcom to invest $1.5 billion to expand and modernize its manufacturing facilities in Fort Collins, Colorado. It is part of Apple’s commitment in August to invest $600 billion as part of its “American Manufacturing Program” which it said is dedicated to bringing even more of the company’s supply chain and advanced manufacturing back to the US.

Apple’s desktop platforms also remain a major part of the picture. StatCounter lists OS X at 11.89% and macOS at 4.48% for June 2026, meaning Apple’s combined desktop presence remains comfortably ahead of Linux in the global chart. Chrome OS follows with 1.21%.

Of course, StatCounter’s numbers should be read for what they are: web usage statistics, not a direct count of installed operating systems. The company calculates its Global Stats from page views across websites using its tracking code, analyzing details such as browser, operating system, and screen resolution. In other words, the figures reflect measured web activity rather than the number of machines actually installed worldwide.

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 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.

Valve has released Proton 11.0-1, a major update to its Windows compatibility layer for Linux that makes more games playable while fixing a long list of bugs affecting existing titles. The release restores compatibility for many EA games after a recent EA App update, moves classics like Resident Evil (1996), Resident Evil 2 (1998), Dino Crisis, and SHOGUN: Total War from Proton Experimental into the stable release, and adds support for games including Gothic 1 Classic, X-Plane 12, Breath of Fire IV, and Deadly Premonition. Valve also fixed crashes in HELLDIVERS 2, restored No Man’s Sky VR support, improved Steam Overlay compatibility with EA games, addressed KDE and GNOME desktop issues, and rebased Proton on Wine 11.0 with updated graphics components.

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.

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.

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.

Meta launched its inaugural AI image model from the Meta Superintelligence Labs on Tuesday, its effort to compete with the likes of OpenAI’s GPT Images 2.0 and Google’s Nano Banana 2 in the AI image generation race. The new model, called Muse Image, rolled out with deep integrations woven into the Instagram app. As part of this update, public Instagram profiles are now automatically opted into being fodder for generative AI remixes. All someone has to do is tag your account’s profile in a prompt — if it’s public — and they can use Meta AI to generate an image using your likeness.

Meta positions this feature as a cheeky way to personalize generations with images of real people. “Whether you want to design a custom event invitation, mock up a collaborative creative concept, or generate a personalized graphic, tagging a username lets Meta AI use public photos to build a visual that’s ready to post,” reads one of Meta’s announcement blogs about the new AI tool. […] Instagram’s help center site includes more details about how this feature will impact users, saying that “people may be able to create content with your Instagram content using AI features at Meta” if you leave your account public and on the default settings. (A previously archived version of this page from 2025 does not include similar, AI-focused language.)

While neither Microsoft nor id Software have formally acknowledged the layoffs, one former member of the studio’s staff, Michael Maynard, has echoed the 50 percent figure on LinkedIn. According to at least one of Game Developer’s sources, that could translate to around 90 job cuts, though it’s so far unclear what departments at id Software have been hit hardest.

[…] Bloomberg reported yesterday that as part of the “reset” at Xbox, ZeniMax Media, the parent company of id Software, will be focusing on its biggest franchises — like The Elder Scrolls, Fallout, Wolfenstein and Doom — going forward. It’s possible that motivated the cuts to id Software, but the developer at least outwardly appears to be already heavily focused on Doom. The studio launched Doom: The Dark Ages in 2025 and an expansion to the game on July 7, 2026. Whatever the reason, the cuts at Xbox aren’t over: While Microsoft eliminated 1,600 roles alongside the announcement that Xbox is restructuring, it still plans to lay off another 1,600 employees over the coming months.
