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.

Information storage in the nervous system requires transcription triggered by synaptically evoked calcium signals. It has been suggested that translocation of calmodulin into the nucleus, initiated by ...

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 ...

Calcium is a very special nutrient. In the cells of most living beings calcium ions function as so-called second messengers to transmit important signals. The same applies equally to animal, plant and ...

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 ...

Our biceps and our brain cells may have more in common than previously thought. New research led by the Lippincott-Schwartz Lab shows that a network of subcellular structures similar to those ...

When plants are infected by pathogens, suffer from a lack of water or have to react to other external stimuli, the first thing they do is increase the proton and calcium concentration in the affected ...
