“This is a critical first step at converting carbon dioxide to oxygen on Mars." The process could one day help astronauts breathe on the red planet. Much larger versions of MOXIE could be used to ...

A new study suggests rising carbon-dioxide levels may be slowly changing human blood chemistry and could impact long term ...

SPOKANE, Wash. — Several social media claims are going viral, claiming that face masks can trap carbon dioxide and prevent oxygen from entering a person's lungs. According to Spokane County Health ...

With a zap, a beam of ultraviolet light can blast carbon dioxide into oxygen gas, O 2. Because the sun hurls the same radiation, the reaction hints that breathable air could have formed on Earth ...

A new study of sediment cores shows a series of massive emissions of carbon dioxide over a 20 million year period about 300 million years ago. These CO2 emissions happened at the same time as drops in ...

A toaster-sized scientific instrument attached to NASA’s Perseverance rover just sucked up a bit of carbon dioxide from the surrounding Martian atmosphere and converted it into oxygen. It’s a ...

Carbon dioxide is being converted into oxygen on Mars thanks to an invention undergoing testing that could lead to the colonization of the red planet. Day and night across the seasons, a ...

A bioreactor has been flown to the International Space Station (ISS) to turn carbon dioxide into oxygen using algae. The lives of the astronauts on-board the ISS will not hinge on it working properly ...

The formation of CO2 is based on the combination of oxygen and carbon. The more carbon entering the atmosphere, the more likely increased CO2 production becomes, reducing available oxygen. Every ...
