Coral reefs have been gaining a lot of attention by conservation groups as environmental and human stresses are causing irreparable damage to these reefs. Stresses such as warming oceans and climate change are going to serve as future obstacles for these coral populations. However, the study of dying corals is complex, and researchers have found that some corals die while others do not, even when exposed to the same environmental conditions. In order to figure out this conundrum, a research team from Northwestern University and The Field Museum of Natural History found that corals themselves play a role in their susceptibility to deadly coral bleaching due to the light-scattering properties of their skeletons.
