Researchers at the University of California, Irvine, have developed a polymeric biohybrid cardiac device that harnesses the power of light to electrically and mechanically control living heart tissue ...

The heart is the only muscle that contracts and relaxes continuously over a lifetime to pump oxygen-rich blood to the body's organs. Researchers at UT Southwestern Medical Center now have identified a ...

The heart relies on finely tuned spatial heterogeneity in wall structure, fibre orientation, blood distribution and ...
