Major discovery helps explain coral bleaching

Nils Rädecker spent more than a year studying a coral reef just off the coast of Thuwal, Saudi Arabia. He then replicated these environmental conditions in the aquaria at the Red Sea Research Center.

Scientists discover slimy microbes that may help keep coral reefs healthy

Corals have evolved over millennia to live, and even thrive, in waters with few nutrients. In healthy reefs, the water is often exceptionally clear, mainly because corals have found ways to make optimal use of the few resources around them. Any change to these conditions can throw a coral’s health off balance. Now, researchers […]

‘Coral hospital’ tool could help safeguard reefs facing climate change — ScienceDaily

Researchers have found a novel way to identify heat-stressed corals, which could help scientists pinpoint the coral species that need protection from warming ocean waters linked to climate change, according to a Rutgers-led study. “This is similar to a blood test to assess human health,” said senior author Debashish Bhattacharya, a Distinguished Professor in the […]

Recovery of an endangered Caribbean coral from parrotfish predation

At a local scale, management efforts to increase populations of parrotfishes are believed to be critically important to maintaining resilient, […]

Gasdermin offers insight into coral necrotic death

Pyroptosis is executed by gasdermin, a family of pore-forming proteins. Gasdermin-mediated pyroptosis is characterized by rapid cell swelling, membrane disruption, […]

Coral ‘tower’ taller than the Empire State Building discovered off Australian coast

An underwater research vessel has stumbled upon a gargantuan coral reef, standing like a monolithic tower off the coast of northern Australia. According to scientists at the Schmidt Ocean Institute, who are conducting a yearlong expedition of the ocean around Australia, this newly discovered reef stands more than 1,640 feet (500 meters) high from base […]
