Mother-of-pearl's genesis identified in mineral's transformation

Among the most intriguing biominerals is nacre, or mother-of-pearl — the silky, iridescent, tougher-than-rock composite that lines the shells of some mollusks…

Tiny carbon-capturing motors may help tackle rising carbon dioxide levels

The proof of concept study represents a promising route to mitigate the buildup of carbon dioxide, a major greenhouse gas in the environment, said researchers….

A more acidic ocean will bend the mermaid's wineglass

The creature in question is Acetabularia acetabulum, commonly called the mermaid's wineglass. Reaching a height of just a few inches, this single-celled alga…

Biotech materials made simple – crystal structures altered by a single protein

Scientists in Haifa and Saarbrücken have now succeeded in replicating the combination of calcium carbonate and biopolymeric compounds which nature took…

How Ionic: Scaffolding Is in Charge of Calcium Carbonate Crystals

Nature packs away carbon in chalk, shells and rocks made by marine organisms that crystallize calcium carbonate. Now, research suggests that the soft, organic…

As CO2 acidifies the oceans, scientists develop a new way to measure its effect on marine ecosystems

Following a 5,000 km long ocean survey, research published in the Proceedings of the National Academy of Sciences presents a new way to measure how the…

Southern Ocean: Iron fertilization might be less efficient for deep-ocean carbon dioxide storage

Lead author Dr. Ian Salter from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI), and a team of international collaborators,…

Arctic sea ice helps remove CO2 from the atmosphere

Due to global warming, larger and larger areas of sea ice melt in the summer and when sea ice  freezes over in the winter it is thinner and more reduced. As…

Researchers convert carbon dioxide into a valuable resource

The product, Precipitated Calcium Carbonate (PCC), is used in e.g. plastics, papers, rubbers and paints. The innovative plant represents the next stage prior…

New research suggests Saharan dust is key to the formation of Bahamas' Great Bank

A new study suggests that Saharan dust played a major role in the formation of the Bahamas islands. Researchers from the University of Miami (UM) Rosenstiel…
