Researchers use biocompatible polydopamine nanoparticles and near-infrared light to remotely trigger activity in neuron and ...

Study: Electrical signaling and coordinated behavior ... Specialized excitable cells, such as neurons and muscles, depend on tightly regulated calcium dynamics—a feature thought to have emerged ...

Calcium tells muscles to contract and nerves to release neurotransmitters, and is at least part of the signal that helps people form and retain memories. What's so mind-boggling about calcium ...

In cell signaling, calcium is king. The flux of calcium ions across cell membranes regulates cellular activities from muscle contraction to neuron firing to immune cell function. A talk I saw here at ...

Calcium is a key mineral in our functioning. The nutrient plays a key role in our bone health, influencing the way our teeth look and function, as well as our strength and muscles. The mineral ...
