Mars Is Full Of Freaking Hearts Everywhere!

I was really surprised when I saw this collection of hearts on Mars posted by El Comanderino Chris Hadfield. How are there so many craters with the shape of hearts in Mars? Are heart shapes pervasive through the entire galaxy? The hell I know. Just forward this post and tell your favourite astronerd you love him/her.


Scientists Grow Human Heart Tissue That Beats With Total Autonomy

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.


How To Grow A Human Heart

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.


The World's Newest Artificial Heart Is Half Cow, Half Machine

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.


US Government Wanted To Make The Perfect Artificial Heart -- With Radioactive Decay

The idea of putting a decaying radioactive isotope inside your chest might make you a little uneasy — and rightly so. But, in 1967, the National Heart Institute and the Atomic Energy Agency set out to make it happen in the form of an plutonium-238-powered atomic heart. Think Tony Stark with nuclear waste in his chest.


This Complex 3D Heart Simulator Can Run On Just A Laptop

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.


The Amazing Story Of The Woman Who Had To Be Upside Down To Stay Alive

Discover Magazine has an amazing story about how a woman needed to be carried upside down in order to stay alive. It sounds crazy, but it’s real. The reason she had to be held upside down was because her pacemaker had disconnected from her heart.


Baby's Life Saved By World's Smallest Artificial Heart

Like all technology, medical implants can be made smaller as the engineering behind them gets more advanced. That’s how a 16-month-old Italian baby was able to become the recipient of the world’s smallest artificial heart — and have its life saved in the process.


New 3D Images Let Doctors See What Causes An Irregular Heartbeat

A healthy heart beats evenly as a metronome, sending oxygen-rich blood to your organs and appendages. But if your ticker’s rhythm isn’t so even, it can lead to fibrillation — rapid, unsynchronised contraction of the muscles that impedes the delivery of blood around the body.


Your Heartbeat Could Be Your Password

A technology in the works might soon allow you to unlock your hard drive by simply touching your keyboard. Your unique heartbeat, emitted through your fingertip, would be your password.
