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

If you're anything like me, you probably toss eggshells in the trash as soon as you crack them. But next time, you might want ...

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

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

Planktonic foraminifera are tiny marine organisms, which are essential to the ocean's carbon cycle. A recent study reveals that these populations are shrinking at an alarming rate due to ocean warming ...

This is different from the chemical that makes up seashells, which is calcium carbonate. Luckily, sea shells and teeth don’t dissolve in water. There is a special soft flexible plastic material that ...

In this activity, you can use a common liquid to detect calcium carbonate! Cover your work surface with newspaper or paper towels. Place some egg shell and an antacid tablet on your work surface. Use ...

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 ...

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 ...

They can readily distinguish natural shells containing calcium carbonate from calcium-bearing replicas made from calcium sulphate. The concentration of calcium detected by the hermit crab is in the ...
