Unprecedented, man-made trends in ocean's acidity

Recent carbon dioxide emissions have pushed the level of seawater acidity far above the range of the natural variability that existed for thousands of years, affecting the calcification rates of shell-forming organism. These ...

Mussels fight back against oceanic acidification

The gradual rise in oceanic acidity is weakening the shells of shellfish, corals and sea urchins, making them vulnerable to predation and damage from oceanic movements.

Sea cucumbers could be key to preserving coral reefs

(PhysOrg.com) -- Tropical sea cucumbers could play a key role in saving coral reefs from the devastating effects of climate change, say scientists at One Tree Island, the University of Sydney's research station on the Great ...

Progress Toward Artificial Tissue?

(PhysOrg.com) -- For modern implants and the growth of artificial tissue and organs, it is important to generate materials with characteristics that closely emulate nature.

Alternative cement with low carbon footprint developed

Researchers at the Martin Luther University Halle-Wittenberg (MLU) in Germany and the Brazilian University of Pará have developed a climate-friendly alternative to conventional cement. Carbon dioxide (CO2) emissions can ...

Sustainable ceramics without a kiln

The manufacture of cement, bricks, bathroom tiles and porcelain crockery normally requires a great deal of heat: a kiln is used to fire the ceramic materials at temperatures well in excess of 1,000°C. Now, material scientists ...

Major changes needed for coral reef survival

To prevent coral reefs around the world from dying off, deep cuts in carbon dioxide emissions are required, says a new study from Carnegie's Katharine Ricke and Ken Caldeira. They find that all existing coral reefs will be ...
