A new study published in the journal Nature Geoscience found evidence of oxygen production near polymetallic nodules located deep in the ocean. Called dark oxygen, this oxygen is being produced ...

A 2024 study that claimed to have discovered an entirely new source of oxygen in the deep sea — dubbed "dark oxygen" — was flawed, inconsistent with previous research, and "fundamentally at odds with ...

Mitochondria are integral to cellular bioenergetics, utilising nutrient oxidation to drive ATP synthesis while concurrently generating reactive oxygen species (ROS), including superoxide and hydrogen ...

For decades, scientists have taught that most oxygen in Earth’s oceans is produced through photosynthesis, a process in which plants and microscopic algae use sunlight to split water molecules and ...

Potato-shaped metallic nodules deep under the Pacific Ocean produce oxygen in complete darkness, challenging previous assumptions about oxygen production. The discovery of "dark oxygen" raises ...

Oxygen-producing rocks have been found on the deep seafloor, challenging what we know about oxygen production. I don’t know about you, but when I learned about oxygen production, it involved plants, ...

Researchers studied the fate of the material produced by Posidonia seagrass meadows. This study, carried out in the Mediterranean Sea at STARESO, shows that the dead leaves of what is commonly known ...

Benthic diatoms are the most important and biodiverse primary producers in streams and comprise the basis for the food webs, fueling animals such as insects and stream fishes including trout. Benthic ...
