“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 ...

We all need oxygen to survive, and carbon dioxide kills us. Makes sense, right? Apply that same logic to Starfield, and you’ll more or less get an idea of what these meters mean in the game. Here’s ...

Scientists have discovered a new way to make molecular oxygen (O2) from carbon dioxide (CO2) -- no green plants involved. Their findings could alter our understanding of the Earth’s early atmosphere ...

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 ...

At the same time, plants play the most important role, since they not only absorb CO2 but also produce oxygen, which is of great importance to people and animals. But if moss, shrubs, and other ...

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 ...

Low-oxygen "dead zones" in the ocean could expand significantly over the next century, according to marine chemists. These predictions are based on the fact that, as more and more carbon dioxide ...

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 ...

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 ...
