As the mid-winter break draws crowds to beaches, tourists may be wondering if their sunscreen is toxic to coral reefs.
Despite bans around the world, there's no empirical evidence sunscreens cause coral bleaching.
A look at new research published in 2018 on fossa, deepsea corals and tropical frogs developing resistance to a deadly fungus.
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.
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.
Scientists have used 'tree rings' in coral to identify centuries of stress.
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.
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.
If researchers shared their data, we could take a big step towards saving the world's coral reefs.
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.
Every year buoyant bundles rise from a spawning coral, giving the impression of an upside-down snowstorm.
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.
Scientists have just discovered an unusual symbiotic relationship between crabs and living corals.
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.
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. 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.
