Pyroxenes are a major group of rock-forming minerals. Scientists investigated the iron ion status of a calcium-rich pyroxene, using Mössbauer spectroscopy on thin sections of single crystals. The ...

In tetrameric cation channels, a phenomenon known as divalent cation block is known to occur: the blocking of ion transport due to the presence of divalent cations such as calcium (Ca 2+) or magnesium ...

In a recent study posted to the bioRxiv* preprint server, researchers investigated severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) envelope (E) protein activity in terms of calcium ...
