Microsoft has quietly extended free Windows 10 security updates for consumers by another year, pushing the Extended Security Updates (ESU) program's end date from October 12, 2026, to October 12, 2027. "The ESU support page was updated with that date, and Microsoft's blog post on the program has a new editor's note confirming the change," reports Ars Technica. From the report: The prevalence of Windows across so many devices and form factors has given Microsoft a massive customer base for decades, but it has also stymied the company's efforts to roll out new operating systems. Microsoft famously extended the support window for Windows XP numerous times throughout the 2010s as it became apparent that millions of PCs would never be updated. Windows 10 isn't quite as entrenched as XP was, but it has still been a slog getting people to upgrade to Windows 11 even nearly five years after release. Unlike many past Windows updates, Windows 11 required some users to buy new PCs with specific CPU technologies and a Trusted Platform Module (TPM). Microsoft was widely criticized for excluding perfectly serviceable PCs, and that's turning into a problem in 2026. The AI-driven shortage of storage and memory has made system upgrades vastly more expensive, potentially slowing upgrades. Some have also avoided Windows 11 due to Microsoft's intense focus on AI features. The result is that Windows 10 remains stubbornly popular. According to StatCounter data, Windows 10 is still running on about 26 percent of PCs, while Windows 11 sits at 72 percent. That means there are still hundreds of millions of active Windows 10 installs, but those machines will be up to date for at least an additional year.

schwit1 shares a report from The Wall Street Journal: The European Union Aviation Safety Agency has ordered (PDF) urgent inspections of 16 Airbus A380 planes operated by Emirates and Qantas, after cracks were found in a wing component on some aircraft (source paywalled; alternative source).. Cracks were found during earlier inspections of the wing spars structure, a key component of the wing, EASA said in a directive effective Wednesday. EASA determined that they "could reduce the structural integrity of the wing." "To address this potential unsafe condition, Airbus determined that an additional special detailed inspection has to be accomplished," EASA said. The first group of five aircraft, operated by Emirates, need to be inspected immediately, while the second group of 11 aircraft can be inspected later but within 25 flight cycles, EASA said in a separate statement. From the second group, 10 are operated by Emirates and one by Qantas, the aviation safety agency said.

Notion announced that it will shut down its email client on September 22. The company says more than half of users already manage email through Notion's AI agents without opening their inbox, so it is shifting its focus from a traditional email client to agent-run workflows. Engadget reports: It has published an FAQ for users to make sure that they don't lose any messages or data in the transition. Most emails will still exist in a Gmail inbox, but customers will need to manually export their drafts, scheduled emails, snippets and auto label instructions. Notion first began offering Notion Mail after acquiring startup Skiff in 2024.

Researchers say they detected the first gravitational-wave "fingerprints" of a black hole's event horizon by analyzing the final moments of the powerful GW250114 merger. The findings support Einstein's general relativity and may eventually help probe frame dragging and quantum fluctuations near black holes. Phys.org reports: For the new research published in Nature, an international team of researchers analyzed data from the strongest gravitational wave ever recorded, known as GW250114, detected by the LIGO observatory in January 2025. By isolating the last burst of waves -- known as "direct waves" -- from this black hole merger, the scientists said they were able to extract information from closer to an event horizon than ever before. "This black hole horizon concept normally appears in science fiction," lead study author Sizheng Ma of the Perimeter Institute for Theoretical Physics in Canada told AFP. "But now we are really able to touch the region around the horizon with gravitational data," he added. "Sometimes I cannot believe this is really happening." The last stage of two black holes merging is like a spoon stirring a glass of water, Ma explained. The resulting swirl in space creates the ripple of gravitational waves that travel at the speed of light in all directions. If the metaphorical spoon is stirring close enough to the black hole's event horizon, "this offers us a chance to decode the physics around that region," Ma said. By supporting the theory of general relativity, the results "proved that Einstein was correct again," he added. The scientists emphasized that more research was needed to decipher what can be gleaned about event horizons using this method. But they did detect information about how black holes twist space around themselves as they rotate -- a phenomenon known as "frame dragging." "This is similar to pushing a glass into a table and twisting it, so that the tablecloth winds up around it," Maximiliano Isi, a gravitational wave astrophysicist at Columbia University, told AFP. In the future, the scientists hope to find signs of tiny changes known as quantum fluctuations. "In this way, we can really probe this near-horizon region to look for new physics," including searching for a deviation from general relativity, Ma said.

An anonymous reader quotes a report from Reuters: Spain will require mobile networks to have backup systems that maintain connectivity when power outages occur. Per a royal decree that will be approved by the end of 2026, mobile network operators (MNOs) and infrastructure companies will need to install batteries or other backups to keep service active for at least four hours during a blackout. The mobile network rules will apply to businesses that serve at least 500,000 users or generate upwards of 50 million euros ($56.9 million) in annual revenue. The decree will stipulate that half of the population will need to be covered by this failsafe within the first year, then 65 percent in the second year and three quarters in the third. [...] The decree will require other key infrastructure elements to remain up and running for a certain period after a power outage. For instance, control centers that could impact all of Spain if they were to go offline will need to remain in service for at least 24 hours. Emergency call centers will also need to have plans in place to maintain operations, as Reuters notes. The move is in response to the widespread blackout across the Iberian peninsula in 2025, which left more than 50 million people without power. Experts called it "the most severe and unprecedented blackout that had occurred in Europe in the past 20 years."
