Glowing coral reefs are striving to recover from bleaching, study says

(CNN)As oceans warm due to climate change, some coral reefs have been devastated in recent years by bleaching events that cause them to die and damage the biodiversity that depends on them.

Multiple studies are underway to understand more about these bleaching events and if corals can bounce back.
