Iron oxide minerals are found in rocks around the globe. Some are magnetic, and some of them rust—especially when exposed to water and oxygen. These characteristics provide clues about the history of ...

Last week, beachgoers off an Iranian island were met by an eerie sight. The sand turned bright red as if the shoreline was ...

A study suggests Mars takes its red hue from a type of mineral that forms in cool water, which could reveal insights about whether Mars was ever able to support life.

"Iron oxides trap phosphorus because they have different charges ... Because phosphorus is a finite resource—mined from phosphate rock found only in the United States, Morocco and China—its supply is ...

"We were trying to create a replica Martian dust in the laboratory using different types of iron oxide. We found that ferrihydrite mixed with basalt, a volcanic rock, best fits the minerals seen ...

“We were trying to create a replica martian dust in the laboratory using different types of iron oxide. We found that ferrihydrite mixed with basalt, a volcanic rock, best fits the minerals seen ...

the iron bound up in its rocks reacted with water and oxygen in the air, similar to how rust forms here on Earth. The resulting iron oxide was then broken down into dust and was spread around the ...

Northwestern researchers made progress on new biochemical possibilities this week, in both the human brain and everyday ...
