The chemistry of shells of plankton called foraminifera are a record of past climate. Recent experiments show magnesium levels vary in foram shells due to different growth rates during daily ...

For the first time scientists can see how the shells of tiny marine organisms grow atom-by-atom, a new study reports. The advance provides new insights into the mechanisms of biomineralization and ...

Chronicling Earth's past temperature swings is a basic part of understanding climate change. One of the best records of past ocean temperatures can be found in the shells of marine creatures called ...
