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 ...

To understand the earliest phases of epidermal cell spreading we have sought a defined in vitro system. We studied the divalent cation dependence of guinea pig epidermal cell spreading in media ...

2,4-dichlorophenoxyacetic acid (2,4-D) is a common ingredient in POST broadleaf herbicides labeled for use in turf, pastures, rangeland, and grain crops. The herbicide 2,4-D is a weak acid, and when ...

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 ...

New research reveals role for calcium ions in chromosome condensation during mitosis; high-resolution imaging of living cells reveals compact, globular chromosomes in the presence of calcium that ...

Calcium is the third most abundant metal in the earth’s crust. It is trimorphic in structure and its hardness is greater than that of sodium. It is less chemically reactive than alkaline metals. The ...
