Electrical zap of cells shapes growing brains
Researchers tweaked voltage in frog embryo cell membranes, telling tissue where to grow and even fixing defects

VOLT JOLT Researchers changed the voltage in frog embryo brain cells (iii) to fix the damage caused by a mutation that makes the brain grow abnormally (ii), and make its development more like that of a normal embryo (i). Markers point to differences in brain development.
