Study the effect of long-term oxygen deficiency

Researchers at LuleƄ University of Technology have developed a method to study how muscle cells in the blood vessels of the lung permanently contract because of long-term oxygen deficiency. This phenomenon leads to increased ...

How nutrients are removed in oxygen-depleted regions of the ocean

In the course of global climate change, scientists are observing the increase of low-oxygen areas in the ocean, also termed oxygen minimum zones (OMZs). Large-scale OMZs exist, for example, in the Pacific off the coast of ...

Stable, self-disrupting microbubbles as intravenous oxygen carriers

Severe oxygen deficiency eventually leads to cardiac arrest. If the blood's oxygen content cannot be rapidly re-established, the patient may die within minutes. In the journal Angewandte Chemie, American scientists have introduced ...

Global ocean de-oxygenation quantified

Oxygen is an essential necessity of life on land. The same applies for almost all organisms in the ocean. However, the oxygen supply in the oceans is threatened by global warming in two ways: Warmer surface waters take up ...

Female fish judge males on DIY skills, study shows

Female fish judge males based on their ability to design nests best suited for the conditions of their environment, according to a new study by University of Leicester researchers.

Oxygen in stars

Oxygen is the third most abundant element in the universe, after hydrogen and helium. It is an important constituent of the clouds of gas and dust in space, especially when combined in molecules with other atoms like carbon, ...
