| Description: |
Coccolithophores are phytoplankton known for their remarkable ability to build chalk (calcium carbonate) scales inside their
cells, which are secreted to form a protective armour on the cell surface. A team of scientists report that coccolithophores
use a similar mechanism to the one previously characterised in vertebrate cells, to facilitate calcification. They found that this
process may be directly affected by the current increasing levels of dissolved carbon dioxide in the oceans. [Source:
