Removing excess carbon dioxide (CO2) from the atmosphere may be essential to curb severe climate change. Possible, but expensive, methods include burying the gas underground between rock layers or ...

Researchers have found an explanation for why very little nitrogen could previously be accounted for in the nebulous covering of comets: the building block for life predominantly occurs in the form of ...

Liman and her team of researchers published their findings earlier this month in the journal “Nature Communications.” They wrote in the introduction to the study that ammonium — and its gas, ammonia — ...

An international team led by astronomers at Leiden University has shown in laboratory experiments that sulfur can bind with ammonium under icy cosmic conditions and form a salt that sticks to dust and ...
