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
The retina is a complex and fragile piece of equipment, but without it, the world would be completely dark. With a number of diseases that can erode the delicate tissue… read more
For the recorder of potentially breakthrough medical technology, sometimes it seems that the list is just so many applications of three new technologies: smaller electronics, new materials and stem cells…. read more
You’ve probably never heard of Valter Longo, but if you’ve heard about the purported health benefits of intermittent fasting, you’ve likely been exposed to his work. A University of Southern… read more
It turns out that an apple a day — or at least an apple spinach salad — does keep the doctor away. But it’s not true that when brain cells… read more
Kids learn with robots; 3D printed liver, no stem cells required, robotic furniture; living forever as computer code
Stanford researchers found that simply by producing stem cells from adult male skin cells and putting them in the sperm-making tubes of mice, they could obtain partly developed germ cells, the cells that produce sperm. The researchers hypothesized that if the cells had been placed in human testes, with their distinct and roomier topography, they would likely have resulted in functional sperm.
The idea that blood is the basic stuff of life dates back to well before the scientific method. Yet, in a pair of new studies, researchers have found that blood — and specifically a growth factor in it known as GDF-11 — spurs the brains, muscles, skeletons and hearts of older mice to look and perform like those of younger mice.
3d printing houses, neighborhoods, and audio speakers; growing new cartilage in the lab; Congressional bipartisanship over online privacy.
Researchers have successfully produced skin in the lab that reproduces the skin barrier. The advance presents a viable alternative to animal testing for cosmetics.
Computers’ EQ rises; lab-grown muscles get stronger; Texas goes big in wind power; and researchers create real-time video game interface of the human brain.
