"This is the first time that a non-algae microbe has been shown to influence the ability of corals to survive a heat-stress event."

A new way to preserve coral, called "cryopreservation," opens a path to year-round sample collection, critical for managing ocean threats.

Marine biologists have discovered the remnants of ancient RNA viruses embedded in the DNA of symbiotic organisms living inside reef-building corals.

"We were surprised at how significant a role dust accumulation played in switching coral reefs from a CO2 source to a CO2 sink."

Coral bleaching can make it harder for fish to recognize their competitors and avoid fights. That can use up a lot of precious energy.

Disease-resistant corals may be able to "rescue" corals that are more vulnerable to stress and disease, researchers say.

Rapid action to significantly reduce emissions could delay the onset of critically warm ocean temperatures and save still healthy coral reefs.

New research indicates a better way to raise long-spined sea urchins for repopulating coral reef ecosystems.

New research documents Indo-Pacific bottlenose dolphins lining up to treat skin conditions by rubbing against corals. Analysis of the corals backs them up.

"It would be a sad irony if ecotourism aimed at protecting coral reefs were actually exacerbating their decline." Here's the trouble with sunscreen.
