Despite being scattered across more than a million square kilometers, new research has revealed that remote coral reefs across the Seychelles are closely related. Using genetic analyses and oceanographic modelling, researchers demonstrated for the first time that a network of ocean currents scatter significant numbers of larvae between these distant islands, acting as a 'coral superhighway.'

Winter storms known as western disturbances that provide crucial snow and rainfall to northern India are arriving significantly later in the year.

While the majority of the world's reefs are now under threat or even damaged potentially beyond repair, a new study offers some encouraging news: efforts to restore coral reefs not only increase coral cover, but they can also bring back important ecosystem functions, and surprisingly fast.

Producing coral skeleton components in the easy-to-use soft-bodied sea anemone Nematostella creates a perfect lab system for studying, and eventually helping, corals threatened by a changing climate.

In a new study, researchers have used the fossil record to better understand what factors make animals more vulnerable to extinction from climate change. The results could help to identify species most at risk today from human-driven climate change.

For many hundreds of millions of years, the average temperature at the surface of the Earth has varied by not much more than 20 degrees Celsius, facilitating life on our planet. To maintain such stable temperatures, Earth appears to have a 'thermostat' that regulates the concentration of atmospheric carbon dioxide over geological timescales, influencing global temperatures. The erosion and weathering of rocks are important parts of this 'thermostat.'

A recent study showed that it is possible to discern the composition of a buried pipe by striking an accessible portion of it and monitoring the sound waves that reach the surface. This method could help water utility companies verify the location of lead water lines without having to break ground.

Despite marine sponges being widespread on our planet, their biodiversity and distribution is still poorly known. Even though the Mediterranean Sea is the most explored sea on Earth, a study reveals the presence of new sponge species and new records in unexplored habitats such as underwater caves or mountains around the Balearic Islands.

In order to keep the population of harbour porpoises in Danish coastal waters stable, only 24 can perish in fishing nets each year. However, over 900 die each year.

A new study provides insights into the role of microbes and their interaction as drivers of interspecific differences in coral thermal bleaching.

Getting climate models to mimic real-time observations when it comes to warming is critical -- small discrepancies can lead to misunderstandings about the rate of global warming as the climate changes. A new study that when modeling warming trends in the Pacific Ocean, there is still a missing piece to the modeling puzzle: the effect of wind on ocean currents in the equatorial Pacific.

At present, viscose textiles are made of biomass from the forest, and there is no such thing as fully recycled viscose. Researchers have now succeeded in making new viscose -- from worn-out cotton sheets.

Scientists have discovered the gene that enables marine algae to make a unique type of chlorophyll. They successfully implanted this gene in a land plant, paving the way for better crop yields on less land.

Researchers have discovered that nanoscale devices harnessing the hydroelectric effect can harvest electricity from the evaporation of fluids with higher ion concentrations than purified water, revealing a vast untapped energy potential.

The findings suggest that subtropical seagrasses are less resilient to heavy grazing from marine herbivores, in part because they receive less sunlight relative to their tropical counterparts. As tropical herbivores move into subtropical waters, overgrazing may prevent subtropical seagrass meadows from persisting in these environments.

Marine biologists have discovered a new species of deep-sea worm living near a methane seep some 50 kilometers (30 miles) off the Pacific coast of Costa Rica.
