A Canadian startup is transforming toxic asbestos mine waste into valuable, carbon-neutral materials for EV batteries and CO₂ ...

“The discovery of abundant siderite in Gale Crater represents both a surprising and important breakthrough in our understanding of the geologic and atmospheric evolution of Mars,” Benjamin Tutolo, ...

For decades, scientists have debated what wiped out the dinosaurs 66 million years ago. The usual suspects? A massive ...

AFP/Getty Images Carbonate minerals typically form when carbon dioxide reacts with water and rock — which makes them a cosmic calling card for life-friendly environments. Scientists have spotted ...

The proof-of-concept results show that, if scalable, the approach could help reduce ocean carbon oversaturation, especially in the Northern Hemisphere where the most wastewater treatment plants are ...

Scientists say the discovery of siderite, a type of iron carbonate, could be crucial evidence to support the theory that Mars once had a thick carbon dioxide-rich atmosphere, allowing a warm ...

Hundreds of students from across southwest Minnesota stepped out of the classroom to meet at Southwest Minnesota State ...

The government aims to capture 8.5 million tonnes of carbon dioxide (CO 2) per year in Track-1 ... carbon capture and storage (BECCS), which in theory would make bioenergy carbon neutral by capturing ...

This carbon dioxide and water should have reacted with ... amounts of carbonate on the planet’s surface predicted by this theory. But that’s all just changed, thanks to data collected by ...

All evidence points to Mars having had a carbon dioxide-rich atmosphere billions of years ago, but insufficient carbonates in Martian soil challenge this theory. Now, a new study using data from ...

A previous theory suggested that an impact would create degassed ... meteorites cause chemical reactions that “produce extremely hot carbon monoxide and carbon dioxide gases,” according to a statement ...
