Humanity is moving from evolution by natural selection (Darwinism) to evolution by intelligent direction. For most of human history, our average age was only about 26 years old. We would… read more
You are a collection of over 30 trillion human cells. Every one of these cells, those in your brain, lungs, liver, skin, and everywhere else, derives from a single pluripotent… read more
First came lab-grown mini-hearts. Then came 3D printed skin. Now scientists have taken “body on a chip” to a whole new level. Starting with skin cells from patient biopsies, scientists… read more
There’s something almost alchemical going on at the Wake Forest Institute for Regenerative Medicine. Scientists there have genetically transformed skin cells into heart cells and used them to 3D print… read more
As the year draws to a close, it’s worth glancing over our shoulder. What technologies and themes were brightest in 2014? Read on. (And keep in mind, attempting such a summation is ambitious… read more
Globally, organ failure is a leading cause of death. But transplantable organs are in far too short of a supply around the world to help many in need—even former Vice… read more
Not long ago, we told you about a patient who received a stem cell treatment for degenerative eye disease. In that story, researchers took the patient’s skin cells and turned… read more
Since stem cells were first hailed as a potential cure for a variety of diseases, we have witnessed setbacks, controversies, and failures. Now, however, human trials for the use of… read more
Potential treatment for deadly brain cancer; climate change shrinks crops; banking your own stem cells just in case.
In a medical breakthrough, South Korean doctors have successfully implanted an artificial trachea into a toddler who had been born without the windpipe.
At the beginning of March of this year, a radical surgery was performed on an American patient: 75 percent of his skull was replaced with a 3D printed implant. The company that produced the implant, Oxford Performance Materials, made the announcement though offered little detail about the patient or the procedure. The surgery was given the green light by the Food and Drug Administration in February.
Microchimerism results when cells from two genetically distinct populations appear in the same tissue, organ, or individual, such as occurs during an organ transplant or during pregnancy. It has been known… read more
