At least fifty calves and three human beings are living with no pulse in their bodies, thanks to an artificial pump that replaced their naturally-grown hearts, as detailed in a story from Popular Science. Doctors Bud Frazier and Billy Cohn devised the artificial organ, and it can completely replace a heart and provide a continuous flow of blood throughout a body without recreating a pulse. While the pulse produced by a creature's heart is an age-old indicator of life and death, it's been a tricky thing for the medical field to replicate — but the pulse doesn't appear to be necessary for life. Cohn tells Popular Science that "I think we're on the verge, right now, of solving the artificial-heart problem for good. All we had to do was get rid of the pulse."
