So why do so many life-forms breathe oxygen? There are probably thousands of kinds of metabolisms, or chemical processes that ...

A new study suggests that the first water molecules in the universe may have formed far earlier than previously assumed ...

Water molecules are so attracted to each other that even after the balloon pops, the water molecules stay together keeping the shape of the balloon. In the water molecule, the oxygen and hydrogen ...

Dissolved oxygen is a measure of the amount of gaseous oxygen (as O 2) dissolved in water. Oxygen enters the river water from the atmosphere (via diffusion), from groundwater, and also as a by-product ...

Oxygen is crucial for aquatic life to thrive. But levels of dissolved oxygen have declined in many watery environments, ...

and different types of sediment or water affect the overall conditions. Using this so-called "biogeochemical model," we have shown that in warm, shallow waters, oxygen levels could fluctuate ...
