Just like us, corals breathe in oxygen and eat organic carbon. And just like us, as a byproduct of converting energy and oxygen in the body, corals produce reactive oxygen species (ROS), a family of chemical compounds that ...

It has been known in biology for a long time that the excited oxygen molecule singlet oxygen is the main cause of ageing in cells. To counter this, nature uses an enzyme called superoxide dismutase to eliminate superoxide ...

Scientists have called superoxide out as the main culprit behind coral bleaching: The idea is that as this toxin build up inside coral cells, the corals fight back by ejecting the tiny energy- and color-producing algae living ...
