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 ...

Your soil is most depleted after a full season of crop demand, making fall ideal for testing. In milder western regions, soil ...

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 ...

Scientists have uncovered a surprising role for calcium in shaping the building blocks of life. Their study reveals that calcium ions help determine the molecular 'handedness' (chirality) of tartaric ...

The first high resolution structure of an ATP-dependent cation pump of the P-type family — the Ca 2+-ATPase from the sarcoplasmic reticulum of rabbit muscle — has now been determined. Figure 1: ...

A water softener reduces the dissolved calcium, magnesium, and to some degree manganese and ferrous iron ion concentration in ...

Researchers simultaneously substituted calcium at the bismuth site and ruthenium or iridium at the iron site to suppress the cycloidal spin structure, enabling room-temperature weak ferromagnetism and ...

Lithium has reigned in the battery world for decades. Researchers have tried for years to make a cheaper, more sustainable successor to lithium-ion batteries by using the element’s more common ...
