Rock weathering may have led to 'Snowball Earth'
Carbon dioxide "breathing phenomenon" found in clay minerals
Japanese researchers have discovered a new phenomenon whereby carbonate ions (CO32−) in a clay mineral called "hydrotalcite" are repeatedly exchanged with carbon dioxide (CO2) in the air, quickly over several ...

Ancient fresh water lake on Mars could have sustained life, Curiosity researchers show
Scientists have found evidence that there was once an ancient lake on Mars that may have been able to support life, in research published today in the journal Science.
Scientists probe abandoned mine for clues about permanent CO2 sequestration
An abandoned mineral mine near Stanford University is providing geoscientists new insights on how to permanently entomb greenhouse gas emissions in the Earth.
Secrets of the legless, leaping land fish (w/ Video)
One of the world's strangest animals – a legless, leaping fish that lives on land - uses camouflage to avoid attacks by predators such as birds, lizards and crabs, new research shows.
