Non-Commercial (NC): Only non-commercial uses of the work are permitted. Molecular fluorescence is typically reduced or “quenched” by dissolved oxygen present in solutions. Quenching mechanisms are ...

Languages: English. Deep-sea researchers have launched a groundbreaking project to investigate "dark oxygen"—a form of oxygen produced in total darkness on the ocean floor. The initiative ...

When OpenAI announced a new generative artificial-intelligence (AI) model, called o3, a few days before Christmas, it aroused both excitement and scepticism. Excitement from those who expected its ...

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. Initial research ...

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 ...

Our findings suggest that simple metal–oxygen–metal motifs, common on the surface of both crystalline and amorphous metal (oxy)hydroxide films, can promote both AEM and LOM mechanisms under typical ...

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%.
