A new study proposes using shoebox-sized detector satellites to sniff out nuclear weapons launched by adversary nations. The idea is aimed at addressing fears that a space-based nuclear detonation could destroy satellites across low Earth orbit and make some orbits unusable for years. Space.com shares the findings from a new paper authored by Areg Danagoulian, an associate professor of nuclear science and engineering at the Massachusetts Institute of Technology: 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 paper has been published in the journal Nature.

An anonymous reader quotes a report from The Guardian: 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.

oumuamua writes: 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."

John Deere has agreed to a 10-year FTC-supervised right-to-repair settlement requiring it to provide farmers and independent repair shops with the same repair resources available to authorized dealers. The deal resolves antitrust claims from the FTC and five states alleging Deere monopolized equipment repair services, contributing to higher costs and delays for farmers. Wired reports: 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."
