A startling discovery made public in July that metallic rocks were apparently producing oxygen on the Pacific Ocean’s seabed, where no light can penetrate, was a scientific bombshell.

If oxygen can be made in the dark ocean on Earth, researchers believe it could be happening on other planets Scientists who recently discovered that metal lumps on the dark seabed make oxygen ...

Scientists who recently discovered that metal lumps on the dark seabed make oxygen, have announced plans to study the deepest parts of Earth's oceans in order to understand the strange phenomenon.

A PaO2 test measures partial pressure of oxygen, or PaO2—the oxygen pressure in arterial blood. The PaO2 reflects how well oxygen is able to move from the lungs to the blood. It is often altered by ...

Specifically, the blue-green algae (or cyanobacteria) that emerged and proliferated about 2.4 billion years ago would have been able to produce more oxygen as a metabolic by-product because Earth's ...

People with obstructive sleep apnea (OSA) typically have low oxygen levels when they sleep because of gaps in their breathing. Blood oxygen during sleep is considered low if levels are below 95%.

But you know what was even faster? The removal of the blood oxygen feature at the heart of the patent spat. According to Apple’s website, the two Apple Watches no loger support pulse oximetry ...
