Rocks, particularly the types created by volcanic activity, play a critical role in keeping Earth’s long-term climate stable and cycling carbon dioxide between land, oceans, and the atmosphere.

One potential substance for directly extracting carbon dioxide from the atmosphere and depositing it underground to mitigate the consequences of climate change is magnesium oxide. However, to make the ...

Magnesium oxide is a promising material for capturing carbon dioxide directly from the atmosphere and injecting it deep underground to limit the effects of climate change. But making the method ...

The seeds for Martian clouds may come from the dusty tails of comets. Charged particles, or ions, of magnesium from the cosmic dust can trigger the formation of tiny ice crystals that help form clouds ...

Scientists are exploring ways to use mineral waste from mines to pull huge amounts of carbon dioxide out of the air. On a scorching day this August, Caleb Woodall wielded his shovel like a spear, ...

Want to see a fire that’s so determined that it will burn merrily away even though you rob it of oxygen? Then grab a big block of dry ice and some magnesium and prepare for horror! …and cool visual ...

A 25-year-long study provides the first quantitative measurement of in situ calcium-magnesium silicate mineral dissolution by ants, termites, tree roots, and bare ground. This study reveals that ants ...

Carbon dioxide passed through the solution of magnesium sulfate and magnesium hydroxide converts both to magnesium carbonate or magnesite, which becomes a solid and falls to the bottom. This solid can ...
