A REMEDY FOR DEATH . . . Scientists grow full-sized beating human hearts from stem cells

My bio-science techno-thriller, A REMEDY FOR DEATH, focuses on a group of super-rich trying to re-create themselves in “healthy, horny 21-year-old bodies with all our accumulated savvy from this lifetime”.
Seems far out?
Not so, as hardly a week goes by without elements of just-that being announced by science labs around the world.
Articles report in the online London Independent https://www.indy100.com/article/human-heart-grow-stem-cells-science-transplant-medicine-technology-7521166 and  by Alexandra Ossola in Popular Science  http://www.popsci.com/scientists-grow-transplantable-hearts-with-stem-cells   how not only is this a step toward the scheme of the bad-guys in A REMEDY FOR DEATH, but — better for the world– will ultimately produce many more of the replacement hearts needed by those waiting for heart transplants.

Have a heart? Don’t let it break. Now they can recycle it!

Intriguing article in MIT Technology Review, “Transplant surgeons revive hearts after death.”

These days, we’re familiar with heart transplants from brain-dead patients into others needing a new, healthy heart.

But in a new experimental breakthrough, successes have been achieved in transplanting the hearts of those not brain dead. Yes, there are procedural and ethical issues involved.

Mind you, this involves actual human hearts, not 3-D printed replacements, or bits of heart tissue grown in labs from human stem cells.

But the possibility raises some issues of medical ethics to be explored: if the donor is not brain dead, when and by what criteria can the heart be removed?

Rather than dig in deeply here, I’ll refer you to the article itself. You’ll see a “reanimated” donated heart actually beating outside the bodies of both donor and recipient.  Here’s the link.
