Field samples, satellite measurements and isotopic data have shed new light on corals' eating habits.
Researching the most resilient corals could help us find ways to better protect reefs in the future.
Building an artificial reef.
Coral reefs are in crisis around the world, and may disappear entirely. 3D printing is a new idea to help them – but it won't be a cure all.

The 2016 bleaching event resulted in 30% mortality on the Great Barrier Reef, with many corals dying of the heat before they bleached and the loss of branching corals creating less complex reef structure.
Researchers studied reef sands at Heron Island, Hawaii, Bermuda and Tetiaroa. In this photo, white areas show the predominance of sand on reefs.

Ocean acidification poses an increasing threat to the sediments that form the framework of coral reefs - within around 30 years, these carbonate sands may no longer be able to form.
Coral reefs are some of the most diverse ecosystems in the world.
If researchers shared their data, we could take a big step towards saving the world's coral reefs.
Some reefs are strong sources of coral larvae.
A new study identifies dozens of individual reefs on the Great Barrier Reef that are especially important for coral larvae dispersal and which could help the entire ecosystem bounce back.
During mass spawning events coral young rise from their parents to ocean surface.

Every year buoyant bundles rise from a spawning coral, giving the impression of an upside-down snowstorm.
How the Great Barrier Reef can be helped to help repair the damaged reef.
Corals on the Great Barrier Reef that are tolerant to warmer waters can be used to help repair other parts of the reef damaged by recent coral bleaching events.
Make yourself at home.
Scientists have just discovered an unusual symbiotic relationship between crabs and living corals.
The southern Great Barrier Reef escaped both of the recent mass bleaching events. But time is running out.

Tropical coral reefs can be saved from climate change and other pressures, but the window of opportunity is closing. And reefs are guaranteed to be markedly different in the future.

As the Great Barrier Reef suffers a second wave of mass bleaching, there is a way to get involved.
Hundreds of thousands of crown-of-thorns starfish have invaded North Queensland, devastating reefs.
New research has uncovered a whole new way to combat the devastating crown-of-thorns starfish, by decoding the pheromones that they use to communicate.
The Great Barrier Reef is bleaching again, in its first back-to-back mass bleaching event.
The Great Barrier Reef is bleaching again. Without greater action on climate change and water quality, its World Heritage status could be listed as "in danger".

The British overseas territory faces an environmental crisis.
Bleached corals are still alive, but they are starving, and often die in the following weeks.
Months after record breaking coral bleaching, research teams are taking stock of the damage on the Great Barrier Reef.
