  UK military says it is jamming hostile satellites to defend its own

  The UK military has reportedly used a ground-based electronic warfare system over the past year to jam or block foreign satellites and deter hostile surveillance of sensitive operations. The Ministry of Defence also announced a new Space Effects Squadron to protect British satellites amid rising concerns over space-based threats and GPS disruption.

  Uber ordered to pay $40 million in arbitration over passenger death

  An arbitrator found Uber and its driver liable in the death of Emily Normandin-Parker, awarding $40 million to her parents. The decision centers on allegations that the driver left two intoxicated passengers at an unsafe freeway gore point after a dispute over a cleaning fee.

  Qwen3.8 27B 4-bit quantization keeps benchmark quality

  A benchmark comparison of Qwen3.8 27B quantizations found that the 4-bit Q4_K_M model performs essentially the same as BF16 on GPQA Diamond, IFBench, and Terminal-Bench 2.1 while using far less GPU memory. Performance drops sharply at very aggressive compression, with 1-bit quantization collapsing to near-random results on GPQA Diamond and degrading reasoning further on longer tasks.

  Navigation-heavy jobs linked to lower Alzheimer’s risk

  A 2024 study of nearly 9 million U.S. death certificates found that taxi and ambulance drivers had the lowest Alzheimer’s death rates among 443 occupations. The article suggests that continuous real-time navigation may exercise the hippocampus and help explain the association, drawing support from prior imaging studies of London taxi drivers.

  Civilian Plane Crash Linked to Military GPS Jamming

  A Wired report says a civilian plane crash in New Mexico may have been tied to military GPS blocking or jamming in the area. The story raises concerns about how signals used for navigation can be disrupted near military operations and affect civilian aviation safety.

  Conservationist Uses AI Agent to Turn Public Geospatial Data into Mapping Apps

  A conservationist built Five Megapixel Conservation, an app that aggregates public geospatial and protected-area data to visualize conservation effort at global scale. The project used exe.dev’s AI agent Shelley to connect multiple datasets and prototype the app quickly, then expanded to process large national datasets more efficiently with partial-file access and parallel VMs.

  Subquadratic details sparse-attention model and longer-term architecture plans

  Subquadratic has released benchmarks and a model card for SubQ 1.1 Small, a sparse-attention model designed to handle very long context windows more efficiently than dense transformers. The company says the model performs strongly on long-context retrieval while using far less compute, and it is also preparing non-attention architectures for future systems.
