Animal Health & Public Risk: New World screwworm has reached the US (reported in a Texas calf), with researchers linking its comeback to illegal cattle smuggling and organized crime moving livestock without proper health checks. Wellness-Adjacent Travel Costs: A UK travel finance warning flags that many people may face expensive overseas medical bills if they don’t have a GHIC for state-provided care abroad. Environment & Health Link: Satellite-based research reports mangrove forests are expanding again after decades of decline, supporting fisheries, storm protection, and carbon storage.
