THE classical theory of the mechanism of production of the carbonate fraction of the calcium carbonate of the hen's egg shell is that of Gutowska and Mitchell 1. This theory makes use of the ...

A heart cockle shell has been found to let in light through a design that resembles fiber optic cables. This could inspire ...

Calcium carbonate is referred to as "nature's ceramic" because of its strength—egg shells, surprisingly enough, are as strong as bones, and some egg shells are tough enough to support a human being.

Tiny, solid windows in the shells of heart cockles let in light for the photosynthetic algae inside them – and they could ...

Ocean acidification can negatively affect marine life, causing organisms' shells and skeletons made from calcium carbonate to dissolve. The more acidic the ocean, the faster the shells dissolve. By ...

have the ability to recognise shells suitable for occupation not only by feeling for them, but apparently also by measuring the minute amount of calcium carbonate that is dissolved in the water around ...

A team of marine biologists, ecologists and evolutionary specialists from the University of Chicago, Stanford University and ...
