Grains of Sand: Too Much and Never Enough

by Alka Tripathy-Lang 25 January 202317 February 2023

Sand is a foundational element of our cities, our homes, our landscapes and seascapes. How we will interact with the material in the future, however, is less certain.

Can Decommissioned Mines Become Green Power Generators?

by Sarah Derouin 29 September 202229 September 2022

A new report supports the idea that underground mines can be transformed into energy storage facilities, adding the possibility of on-demand, carbon-free power to energy grids.

This photograph shows the rocky shore of a placid blue lake in front of green forested mountains. The shore is strewn with white and brown rocks and driftwood. A person dressed in black walks along the shore carrying a fishing rod, and there is a small boat visible on the left side of the image.

The Fate of a Lake After a Dramatic Mining Disaster

by Sarah Stanley 9 September 202212 October 2022

Researchers tracked long-term sediment dynamics in Canada’s Quesnel Lake following the 2014 failure of a dam that spilled record-breaking amounts of contaminated mining waste.

A copper mine delves deep into the orange rock of an Arizona desert. More than a dozen even steps have been excavated leading down to a roughly circular depression in the ground. Some of the steps have patches of oxidized copper, a blue-green color. A smooth path large enough for heavy machinery spirals down into the bottom of the mine.
