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
From one point of view, surgery is a fairly barbaric means of improving your health. After all, your body is cut open, organs are moved around or removed, and doctors probe with their… read more
Scientists at the Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland recently unveiled a flexible spinal implant called the electronic dura (or e-Dura) that they say may greatly improve spinal injury rehabilitation. In a… 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
There’s an ancient Indian tale about a ruler who offered the inventor of chess any gift he desired. The sage gestured to a chessboard, “I’ll have one grain of rice… read more
To Aubrey de Grey, the body is a machine. Just as a restored classic car can celebrate its hundredth birthday in peak condition, in the future, we’ll maintain our bodies’ cellular components to stave… 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
There’s something a little creepy-sounding about the phrase “lab-grown organs,” but producing human organs in the lab could have a range of such powerful benefits that, if they became widely… read more
Researchers have successfully produced skin in the lab that reproduces the skin barrier. The advance presents a viable alternative to animal testing for cosmetics.
The work of scientists trying to manufacture major human organs like the brain and heart in the lab has generated a lot of buzz, even though it will most likely… read more
Since the development of induced pluripotent stem cells in 2006, scientists have managed to use the manufactured stem cells like seeds to grow a wide range of tissues and rudimentary organs. But different tissue types have not proven equal, and researchers are still struggling to coax stem cells to take on certain roles: Lung cells have proved difficult to create. Columbia University researchers recently managed to develop functional lung and airway cells from human iPSCs.
Blindness might just be the first major disability to disappear, at least if our high-tech future takes more a utopian than dystopian bent. A bionic eye is already on the market in the United States, and stem cell therapy has been shown to restore sight in mice. Now British scientists have successfully printed retinal cells.
