November 18, 2025, 11:58 PM EST. Seven years after Apple introduced a smartwatch feature that can detect possible atrial fibrillation (A-fib), similar technology is now widespread across wearables. A new meta-analysis of 26 studies reports that these devices show excellent diagnostic accuracy in identifying A-fib. The visuals suggest most devices correctly classify who does and doesn't have A-fib, though concern remains about false positives-even a low rate, amplified across millions of users, can burden cardiologists and healthcare systems.

November 18, 2025, 11:56 PM EST. New York stocks fell Tuesday as Nvidia led a market rout and Bitcoin wobbled, extending a recent pullback after a rally driven by AI optimism. The S&P 500 slipped 1.3%, the Dow shed about 644 points (1.4%), and the Nasdaq dropped 1.8%. Nvidia remained the market's heaviest weight and slid 2.9%, bringing its monthly loss to about 10.5% - a correction by some measures. The stock's size and AI-chip demand help steer the S&P, making its moves felt across investing portfolios. A Bank of America Global Research survey shows fund managers see an AI bubble as the top risk, ahead of bonds, inflation, and trade wars, with many worried that overinvestment in AI and data-center infrastructure may not deliver the expected profits. Bitcoin briefly dipped below $90,000.

November 18, 2025, 11:54 PM EST. An amateur astronomer recently uncovered unusual radio signals believed to originate from SpaceX's secretive Starshield satellites, part of the Starlink constellation operated by U.S. government agencies. The transmissions appear to use frequencies outside standard downlink bands, effectively sending data in the opposite direction (uplinks re-purposed as downlinks) and may conflict with ITU allocations. The signals were detected by Scott Tilley while scanning rarely used spectrum and are now associated with the NRO and the U.S. Space Force's Starshield assets. Space authorities and SpaceX have not publicly confirmed the findings, prompting questions about transparency and spectrum management and whether other spacecraft could be affected. The observations come from a non-peer-reviewed paper that has yet to be independently validated.

November 18, 2025, 11:50 PM EST. Microsoft's first Windows 10 Extended Security Update (ESU) patch, KB5068781, fails to install on devices activated via the Microsoft 365 admin center, delivering error 0x800f0922 (CBS_E_INSTALLERS_FAILED). The issue is under investigation, with no fix yet, marking the second ESU failure in a week after an out-of-band enrollment patch. The ESU program lets commercial customers pay for continued security updates after Windows 10's end of support. As Ignite unfolds, Microsoft is expected to address reliability and stability concerns rather than new features, even as executives tout AI with Copilot. Windows 10 users should monitor for updates and potential workarounds while Microsoft investigates.

November 18, 2025, 11:48 PM EST. Microsoft is extending free security updates for Windows 10 through October 2026 via Extended Security Updates (ESU). For personal devices, you can enroll at no cost using a Microsoft account. The ESU subscription can be applied to up to 10 PCs signed in with the same account. Eligible editions are Windows 10 version 22H2 Home, Pro, Pro Education, and Workstation with the latest cumulative update installed; Enterprise and Education editions are not eligible. Devices must not be joined to an Active Directory domain, Entra, or managed by MDM. You must be signed in with an administrator account to enroll. Once activated, you can sign out and the PC will continue receiving updates through Oct 13, 2026. This avoids hardware refresh while keeping security patches current, delivered automatically on Patch Tuesday.
