PRINTING HEARTS
With heart disease pervasive, many patients need a transplant — but die waiting. An Israeli team announced a possible answer: for the first time, they “printed” a heart using human cells. It was tiny — the size of a rabbit heart — but if they can make organs big enough, the life-saving potential is obvious.
Within a decade, the researchers said, they’d like to see hospitals around the world routinely “printing” implantable organs.
