Zebrafish’s bioelectricity secret can explain human muscle disorders

Electricity acts like a health checkup for our epithelial tissue. As the tissue grows, cells pack together more tightly, which increases the electrical current flowing through each cell’s membrane. A weak, old, or energy-starved cell will struggle to compensate, triggering a response that sends water rushing out of the cell, shriveling it up and marking it for death. When this process goes wrong, it can cause diseases like asthma and cancer. https://www.quantamagazine.org/cells-use-bioelectricit
