The first March for Science, April 22, 2017, Washington DC.
On the eve of the March for Science, a marine biologist explains why she's returning from abroad to speak out for science in the Trump era.

With coral reefs in crisis around the world, many organizations are working to restore them by growing and transplanting healthy corals. A new study spotlights techniques that help restored reefs thrive.
The increasingly bleached coral at Black Point on the Cobourg Peninsula is a worrying sign of what’s to come for other coral reefs in Australia.
Coral bleaching has struck the Northern Territory, adding urgency to the need for better national management strategies for our warming oceans.

Sea snakes spend their lives in the water, giving birth to live young at sea, so why are they only found in some of the world's oceans? The answer lies in a combination of climate and geography.
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.
If you want to live like a local when on holiday, you should defecate like one.
Biofluorescence makes researching cryptic species such as this Lizardfish easier and less harmful.

Much of the world's ocean is teeming with 'cryptic' fish species, which are small and hard to spot. But a new technique shines a light on these fish, which may in turn help to keep our seas healthy.
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.

Coral reefs in the Asia-Pacific have been deluged with an estimated 11.1 billion pieces of plastic waste, increasing the risk of coral disease more than 20-fold.
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.
A vanishing world.
It is estimated that 75% of the world's coral reefs are already threatened.
The extent of future coral bleaching is likely to vary from place to place.

Regional variations in sea temperature can make all the difference between a coral reef suffering major bleaching or surviving as a refuge for corals, new research shows.
Social media posts, such as this image uploaded to Flickr, can be repurposed for reef health monitoring.

Mining social media posts from tourism hotspots such as coral reefs could turn tourists into environmental citizen scientists without them even realising it.
Parts of the Great Barrier Reef’s outer reefs can form a natural barrier to coastal recession, thus protecting urban centres.
Coral bleaching on the Great Barrier Reef could lead to increased vulnerability of Queensland coastal cities and towns, and not only through its impacts on the tourism industry.
Dozens of reefs around the world have bleached in the past three years, of which the Great Barrier Reef was merely the most high-profile.

Amid fears for the world's coral reefs, the UN World Heritage Committee has issued its most wide-ranging statement so far on protecting heritage sites from climate. But the problem doesn't end there.
The Great Barrier Reef is reeling under a combination of bleaching, over-fishing and land clearing.

The Great Barrier Reef has avoided being listed as "in danger" by UNESCO. But celebrating this is dangerously short-sighted.

Cuban and US scientists are forming partnerships to protect coral reefs and fisheries in both countries. But President Trump may soon announce steps to slow or reverse the US opening to Cuba.
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.
