Here's The Gruesome Way A Doctor First Proved The Heart Pumps Blood

Strange as it sounds, European medical doctors didn't know, until the 1600s, that the heart pumps blood around the body. How they proved this seemingly simple fact is one of the most controversial (and gruesome) stories in medicine. » 9/15/14 11:40am 9/15/14 11:40am

This is one of the weirdest medical cases we've read about in a long…

Picture this: a mountain of a man — over seven feet tall, by the looks of it — stands in the ambulance bay entrance of a hospital. Clutched in his hands are the feet of a small woman who is dangling, fully conscious, with her head pointed straight at the floor. She appears to be entirely okay with the situation. A… » 8/27/12 1:43pm 8/27/12 1:43pm

Incredible medical breakthrough allows doctors to inject oxygen into…

In a monumental breakthrough with far ranging implications, cardiologists at the Children's Hospital Boston in Massachusetts have kept suffocating rabbits alive for 15 minutes with injections of oxygen-filled microparticles. The groundbreaking procedure could conceivably prevent millions of deaths each year caused by… » 6/28/12 6:55am 6/28/12 6:55am

The Science of Being Scared to Death

Fear isn't just the mind-killer... it can actually kill your body as well. The notion of being scared to death may sound like a myth, but it does happen to people — and animals. The authors of Zoobiquity: What Animals Can Teach Us About the Health And Science of Healing examined the question in detail. » 6/18/12 3:24pm 6/18/12 3:24pm

Researchers turn skin cells into healthy, beating heart tissue

For the first time ever, scientists have genetically transformed skin cells from heart failure patients into healthy, beating, "young" heart tissue. This is a fantastic achievement for the field of regenerative medicine. » 5/23/12 7:20am 5/23/12 7:20am

Your own heart could provide the stem cells to fix itself

How's this for cool? Cells harvested from your heart could provide the necessary mechanism to repair itself after a heart attack. A new technique called CADUCEUS (CArdiosphere-Derived aUtologous stem CElls to reverse ventricUlar dySfunction) (which, as an aside, is the most grasping attempt at an acronym outside of a… » 2/18/12 9:00am 2/18/12 9:00am

Man has heart attack while eating at The Heart Attack Grill

If you weigh over 350 pounds, you can eat at the Heart Attack Grill for free (according to the Las Vegas eatery's slogan). But if you should keel over, gripping your chest in agony, while scarfing down a triple bypass burger (that's what the monstrosity pictured up top is called), don't expect any of the scantily clad » 2/16/12 2:10pm 2/16/12 2:10pm

Whoa, a Petri Dish That Has a Pulse

A heart won't beat once it's been ripped out of the chest Indiana Jones style. But disembodied heart cells, when nurtured in a petri dish, will beat on their own. » 2/09/12 8:30am 2/09/12 8:30am

Total artificial hearts may be nothing like what you expect

When we see total artificial hearts in science fiction, they are usually metal-and-plastic versions of what we have now, small pumps that magically attach to arteries. But two medical researchers have successfully created working artificial hearts — and they don't beat. They hum. » 6/14/11 5:00pm 6/14/11 5:00pm

A pill that could repair your heart and prevent heart attacks

Scientists have refined tissue repair techniques using stem cells to the point where they believe we might have pills that repair heart muscles in 10 years. Reports the BBC: » 6/10/11 5:00pm 6/10/11 5:00pm

Damaged heart? We can rebuild it.

For the first time, scientists have coaxed a damaged heart to regrow healthy tissues on its own. They applied living "patches" to a heart, in what is a major breakthrough for people recovering from heart attacks. » 5/06/11 5:40pm 5/06/11 5:40pm

Grow Back the Missing Pieces of Your Heart

When raising a building, construction workers first create a scaffold, a rough framework that mimics the structure of the completed project. As it turns out, biological engineers do the same thing when they develop technology that will enable people to repair their own damaged hearts.

Hearts from Dead Bodies Made to Beat Again

Hearts removed from dead rats started beating again after several days in a lab. No, it wasn't caused by that bright green serum from Re-Animator — it was real science at work, and it could mean heart transplants are about to get much, much easier. A completely "dead" heart can be coaxed into beating on its own… » 1/14/08 1:30pm 1/14/08 1:30pm
