Scientists found a magnetic mineral never before seen naturally in Moon samples; Chang’e-6 brought the material back from the lunar surface, where it survived inside tiny impact-glass particles

Scientists found a magnetic mineral never before seen naturally in Moon samples; Chang’e-6 brought the material back from the lunar surface, where it survived inside tiny impact-glass particles

About 4.25 billion years ago, the Moon possessed a powerful core dynamo with a field strength comparable to or even exceeding modern Earth’s. This magnetic field, generated by circulating molten metal, completely shut down as the interior cooled and core crystallisation ceased, leaving the Moon without a global magnetic field in the present. While it … Read more

Norway’s Green Mountain data centre uses 8°C fjord water to cool its servers, turning a naturally cold resource into free refrigeration

Norway’s Green Mountain data centre uses 8°C fjord water to cool its servers, turning a naturally cold resource into free refrigeration

A data centre quietly produces heat every second it is operating. Behind the walls, rows of servers process data continuously, turning large amounts of electricity into computing power and, inevitably, excess heat. That heat has to be removed to keep the equipment within safe operating temperatures, adding significantly to the facility’s energy demand. Green Mountain … Read more

From 1915 to 1972, Mount Rainier stocked more than 9 million fish into naturally fishless waters; today 35 mountain lakes still hold breeding non-native populations that displace amphibians and alter ecosystems

View of the Ohanapecosh River and predated Northwestern Salamanders (Ambrystoma gracile) eaten by introduced trout. Mount Rainier’s glaciers and snowfields feed a magnificent system of icy streams and mountain lakes. On the surface, these waters look pristine, scattered pools in one of America’s most iconic landscapes. But beneath the surface, scientists are looking at a … Read more
