Stable, long-term cell lines will enable scientists to study everything from coral bleaching to biomineralization, knowledge that may help protect corals from ongoing climate change.

Single-cell RNA sequencing helps to catalog the dozens of cell types present in a stony coral, including its elusive immune cells.

In yellow-green and purple versions of the reef-building Acropora tenuis, the genes that code for particular fluorescent and other colorful proteins become more active in the summer, protecting symbiotic algae from thermal stress and resisting bleaching.

Scientists who study the marine ecosystems have frequently failed to involve local researchers in projects, a study finds.

By growing mountainous star corals in the lab and outplanting them to dying reefs, we were able to grow sexually mature corals that could help reef recovery.

Novel technologies establish a new paradigm for global coral reef restoration, with in situ spawning of mature, environmentally resilient corals in five years instead of decades.

Our novel technique involves planting several small fragments of slow-growing corals onto dead coral heads. The fragments eventually fuse, forming a large colony in a fraction of the time that it takes wild corals to build reefs.

Anemones keep their algae populations in check.

From bubbling plants to endangered whales, here are some amazing images from The Scientist in 2019.

A mysterious illness is causing tissue loss in many species.

Some corals can adjust to a range of temperatures, but this ability may be limited in a consistently warmer environment.

Groups of corals release all of their eggs and sperm once a year, but the timing of their spawning is under threat from climate change.

Mycale grandis teams up with microbes housed inside it to gather nutrients.

Runoff and waste may be more harmful to the animals than climate change.

A 3-D simulation shows corals growing into a community.

Stony coral tissue loss disease has already affected 80 percent of Florida’s coastal reef system. Now, a huge team of responders is working to slow its spread and prepare for future restoration efforts.

Diverse plots of corals appeared healthier than monocultures at the end of a 16-month study.

Green fluorescent protein lures algal symbionts to corals.
