A study analyzing these modules reveals that these rocky lumps are capable of producing “dark oxygen” 4,000 meters below sea level where light cannot reach. While this discovery could upend ...

We think of oxygen as life, sustenance, a literal breath of fresh air. But it's actually a very reactive element. Anyone who's burned a log has witnessed this firsthand. So why do so many life ...

Earth's lakes are experiencing an alarming drop in oxygen levels, new research shows. Similar trends have also been observed across rivers and seas. But some lakes are losing oxygen up to nine times ...

Oxygen therapy for COPD is a treatment used to increase the oxygen (O2) in your lungs and bloodstream. Research suggests that people with chronic obstructive pulmonary disease (COPD) who use oxygen ...

Medicare provides coverage for oxygen therapy, including portable oxygen concentrators, under Part B. A doctor must consider oxygen therapy medically necessary for you to qualify for it.

Global warming is causing lakes to lose their oxygen 1. Oxygen is crucial for aquatic life to thrive. But levels of dissolved oxygen have declined in many watery environments, including rivers and ...

A newly developed process helps solve this problem: CO2 is directly split electrochemically into carbon and oxygen. Oxygen could also be produced in this way under water or in space -- without ...

Imagine a world where the oxygen you need changes dramatically between day and night. Your world shifts from being rich in oxygen (oxic) in the day, so you have energy to hunt for food ...

A newly developed process helps solve this problem: CO 2 is directly split electrochemically into carbon and oxygen. As a Chinese research team reports in the journal Angewandte Chemie ...

Metallic nodules found deep in the sea seem to be producing significant amounts of oxygen by some unknown mechanism, researchers revealed last year. Now, we may have found out how it is happening ...

Low-oxygen water, also known as hypoxic water, poses a great risk to aquatic ecosystems. When the oxygen levels in water are too low, it can threaten native fish and other aquatic life. In some places ...
