Global warming's ever-increasing toll on the planet has been a focus of mitigation strategies in recent years, with carbon sequestration projects playing a more prominent role in drawing carbon dioxide out of the atmosphere ...
Japan's Aerospace Exploration Agency sent the Hayabusa2 spacecraft to 162173 Ryugu in 2019, an asteroid in orbit near Earth that is comprised of rocky fragments originating from a larger parent body. Multiple rovers brought ...
Mass extinctions are rapid global decreases in Earth's biodiversity, with five key events identified over the planet's history, arguably the most famous of which occurred ~66 million years ago during the Cretaceous, which ...
MIT geologists have found that a clay mineral on the seafloor, called smectite, has a surprisingly powerful ability to sequester carbon over millions of years.
