A team led by York University researchers has discovered the fastest wind near a supermassive black hole ever found at ultraviolet wavelengths, driven by the disc of matter, or quasar, surrounding the black hole. “This quasar has a black hole of 1.7 billion times the mass of the Sun. That’s typical. What’s not typical is that it has gas moving towards us at 30 per cent of the speed of light,” says York Professor Patrick Hall of the Faculty of Science.

Non-structural disaster measures, including early warnings and evacuation systems, helped improve coastal resilience and reduce storm-surge impacts in Macau, report researchers at Science Tokyo. After analyzing the city’s responses to three major typhoons, which included resident interviews, evaluations of early warning systems, evacuation procedures, and other typhoon mitigation efforts, the study found that earlier issuance of typhoon warnings, color-coded storm-surge alerts, and government-led evacuation guidance significantly improved public trust and reduced disaster impacts.
