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 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 ...

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 ...

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 ...

New study shows that geological storage of low-purity carbon dioxide mixed with oxygen and nitrogen from direct air capture is an environmentally friendly and economically viable approach to remove ...

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 ...

NASA sent the Perseverance rover to Mars with some bonus technology: a device that can turn carbon dioxide into oxygen, much as trees do on Earth. The device, called the Mars Oxygen In-Situ Resource ...
