Carbon cycling in wet soils

Under changing, increasingly dynamic climatic conditions, temperate soils are forecast to experience a high degree of variability in moisture conditions due to periods of drought and/or flood. These periodic shifts between ...

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 ...

Flavor research for consumer protection

In 2013, the German Stiftung Warentest found harmful benzene in drinks with cherry flavor. But how did the substance get into the drinks? Was the source benzaldehyde, an essential component of the cherry flavoring? And if ...

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 ...
