Ancient eruptions may have triggered conditions for oxygen ‘whiffs’ in the atmosphere In a nutshell Massive volcanic events ...

An innovative approach to steel making could eliminate use of coke and resultant carbon emissions forever. The technology now ...

Discover how CO2 training improves oxygen efficiency, mental focus, and endurance for athletes through specialized breathing ...

Scientists found that volcanic eruptions triggered short-lived oxygen spikes before Earth's air became breathable.

It is widely believed that Earth's atmosphere has been rich in oxygen for about 2.5 billion years due to a relatively rapid increase in microorganisms capable of performing photosynthesis. Researchers ...

They have successfully conducted experiments that mimic photosynthesis, converting carbon dioxide and water into oxygen and rocket fuel ingredients. This development is a major step towards long ...

it will accelerate the breakdown of carbon dioxide in the atmosphere. This process is a crucial one for photosynthesis, and its decline will lead to a reduction in oxygen-producing plants.

During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. These sugar molecules are the basis for more complex molecules made by ...

close respirationA chemical reaction that occurs in the mitochondria of cells in which glucose and oxygen react to produce carbon dioxide and water, releasing energy. Photosynthesis is one of the ...

The aspects to be considered include the occurrence and mechanisms of arterial oxygen unsaturation, hyperventilation and factors affecting the level of arterial carbon dioxide tension. Such data ...
