Matters of the heart: Researchers create 3-D beating heart

Matters of the heart can be complicated, but scientists have now found a way to create 3-D heart tissue that beats in synchronized harmony, like a heart in love, that will lead to better understanding of cardiac health and improved treatments. Researchers have devised a way to stick three different types of cardiac cells together, like Velcro, to make heart tissue that beats as one.
