Science today is framed by climate, scale and systems. In Britain, a stark new analysis links the exceptional May and June heatwaves in England and Wales to more than 2,700 excess deaths, with researchers saying over 40% were tied to human-caused warming—an alarming measure of how climate change is already shaping public health. There was a more hopeful environmental story from China, where scientists say decades of work on the so-called Green Great Wall, using straw-grid planting to pin down shifting sands, has slowed desert expansion, even if the gains will require constant maintenance. Elsewhere, the science-and-technology world intersected with policy and infrastructure: Mastercard is reportedly weighing a sale of control of UK payments firm Vocalink, and a coalition of U.S. states is challenging a giant media merger, underscoring how questions of resilience, ownership and long-term stewardship now reach far beyond the lab.
