Coming fresh on the heels of the news that scientists are successfully 3D printing live, working, mini human kidneys, a new report in Nature is giving another burst of hope to the future of organ transplants. For the very first time, a research team has been able to grow human heart tissue that beats totally autonomously in its petri dish home.

Nature has a nice dive into the scientific quest to grow complex organs like a human heart. No, it hasn't been done yet — but it's surprisingly within reach.

Using cow parts to save ailing human hearts isn't anything new — you could even be sitting next to one of our more bovine brethren right now and think nothing of it. But the newest cow-to-heart integration takes a bit of a deeper dive into science fiction land. Soon, a French medical company will begin testing a "bioprosthetic" heart on actual human patients that is part cow, part synthetic, and loaded with software.

Supercomputers let us simulate everything from the weather, to a chess match against a master, to how the human body operates. But researchers at Japan's National Cerebral and Cardiovascular Center have created a detailed 3D simulation of a beating human heart that can run on a laptop, allowing even small hospitals to perform research and complex diagnoses.

In 1952, Dr Forest Dodrill captured national attention when he became the first surgeon to use a mechanical heart pump on a patient at Wayne State University's Harper Hospital in Detroit. There's a reason that heart pump looks like a 12-cylinder engine. It was made by General Motors.

Scientists have successfully controlled a living creature's heart with a laser beam, taking a first step towards technology that could prevent serious heart defects. The procedure used pulses of light to pace the heart of a two-day-old quail embryo.
