A genetic tool could help scientists identify the most resilient types of corals

Elkhorn coral is one of the main varieties of coral that workers on the northern coast of Puerto Rico have been able to restore following damage done by Hurricane Maria in 2017.

A successful coral transplant gives scientists hope for the Great Barrier Reef


In a trial at the reef’s Heron Island off Australia’s east coast, the researchers collected large amounts of coral spawn and eggs late last year, grew them into larvae and then transplanted them into areas of damaged reef.

Coral off the coast of Cuba is flourishing — a rare glimmer of hope for this threatened ecosystem


Rising ocean temperatures and pollution runoff are bleaching and killing corals in oceans across the globe. But corals in some parts of Cuba are not only surviving, they are thriving.

Healthy corals use chemical signals, or smells, to attract fish. New research has found that corals also send out "distress" signals when they're in trouble.

Coral reefs can communicate with fish, and many of them are crying for help


With corals in trouble around the world, researchers are examining the role of smell in telling fish to come to a healthy reef or stay away. That may help scientists find ways to manipulate the smells to help damaged reefs recover.

Pat Colin, a marine scientist at the Coral Reef Research Foundation, explores the waters off of the Pacific island nation of Palau for organisms to send to the National Cancer Institute in the U.S.

Scientists search Palau’s coral reefs for new anti-cancer drugs


One of the more potent reasons for saving species and the environment is that nature is where we find our most powerful medicines. For three decades, a hunt’s been underway on land and sea for molecules that could help fight cancer. That hunt is winding down now in the coral reefs of Palau.

In Palau, scientists hope they’ve found a coral reef to save all coral reefs


Scientists have found a group of corals in the Pacific island nation of Palau that live in water acidic enough to kill most other corals. Now they’re hoping what they learn from the unusual reefs may help save others threatened by the increasing acidity of oceans around the world.
