Calcium (Ca2+) drives many cellular functions, though the way it controls quality of proteins in the endoplasmic reticulum ...

Plants have evolved sophisticated mechanisms to cope with environmental stressors including drought, nutrient deficiency, and extreme temperatures. Central to these adaptive responses is calcium ...

Calcium signalling represents a fundamental process in cellular communication, orchestrating diverse physiological responses from muscle contraction to neurotransmission and gene regulation. At the ...

To acquire an image of calcium signaling, Reto Fiolka, a cell biologist at the University of Texas Southwestern Medical Center, illuminated primary cortical neurons from embryonic rats with three ...

Left: A blue light pulse of 0.1 seconds triggers a calcium signal (red) in guard cells, which is followed by an anion current (black). Right: The influx of calcium into the cell promotes the release ...

A new method exposes key details of the mechanism behind calcium signaling in prokaryotes for the first time. Working in a Listeria monocytogenes model, researchers from Umeå University (Sweden) led ...

Glycine, a non-essential amino acid derived from serine, plays an increasingly recognized role in metabolic regulation.

This influx of calcium at the contact site attracts and activates a kinase called CaMKII, a protein known to be important in memory. CaMKII alters the plasma membrane's biochemical properties, ...

Using optogenetics, researchers have detected a new acid sensor in plant cells that is addressing a cell-internal calcium store. When plants are infected by pathogens, suffer from a lack of water or ...

Medically reviewed by Femi Aremu, PharmD Vitamin C and calcium are both essential nutrients that serve many roles in the body ...

NEW YORK (Reuters Health) - In elderly people, higher levels of calcium in the blood are associated with poorer mental function and faster decline in cognitive ability, Dutch researchers have shown.

“Your bones are constantly remodeling, which means they are repeatedly breaking down old bone and rebuilding new,” says Callins. Adequate calcium helps support this process, giving bones the resources ...
