(Phys.org)—Researchers working out of the University of Copenhagen have published a paper in the journal Science in which they claim that a new method of dating chondrules and calcium-aluminum–rich inclusions (CAIs) is ...
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 will improve our understanding ...
