I’d suggest a box of chocolates to mend a broken heart. Researchers have a different idea: an electrically charged needle that sprays beating heart cells onto damaged tissue.

Heart attacks can damage important tissues, making the heartbeat weak or irregular. This new technology is able to make a 3D patch of living, beating heart cells. The patch could be grafted onto damaged parts of a heart, to help it beat normally. This could improve the lives of many heart attack survivors.
