Enormous amounts of gold lie buried beneath the rubble of New Zealand’s mountains, and scientists are using freshwater fish genetics to find it.
Miners in Alaska rerouted a river to search for gold. One hundred years later, the new channel is teaching scientists how rivers shape Earth.
In Peru, gold mining harms rain forests and human health. Satellite data can now track forest recovery in protected areas and the migration of informal miners to less regulated areas.
The dome is replaced every 5 years, and researchers are studying how to make the gold more durable.
A method combining partial-volume and blurring effects can be used to measure small features in computed tomography data volumes.
Blending geoscience and archaeology, researchers apply a new technique to pinpoint where ancient and unique gold artifacts were crafted.
Long-term climate records could help mining companies and their investors assess the financial risk of water shortages.
