MTorrice writes: "Heart attacks kill muscle cells called cardiomyocytes, leaving behind irreparable tissue damage. If scientists could grow cardiac tissue in the lab, they could perhaps graft patches of healthy tissue onto a patient’s damaged heart. A new carbon nanotube-studded hydrogel mimics heart tissue’s electrical and mechanical properties and serves as a scaffold for lab-grown cardiac tissue that beats spontaneously. Short video of beating tissue included." Link to Original Source
Today's scientific question is: What in the world is electricity?
And where does it go after it leaves the toaster?
