Make up your mind, appendix! Studies show that the organ, often more trouble than it's worth, has evolved independently in mammals over and over again.
The lab-on-a-chip, designed by researchers at John Hopkins, seems like science-fiction lure, but what it has inspired is even more futuristic: living organ-on-a-chip. It's exactly what it sounds like, as hard as that might be to believe: a living organ on a chip.
If you're still not convinced that stem cells are the future of medicine, try this on for size: Japanese researchers have used them to synthesize a fully functioning organ entirely from scratch.
It's like something out of science fiction or a horror movie or both: in order to facilitate transplants, we can now keep human hearts alive and beating and toasty warm inside a special electromechanical box full of fresh blood.
For the first time ever, rats implanted with lab-grown lungs were able to breathe and oxygenate their blood. It's a huge step towards being able to grow organs for people who need replacements, ending the need for live-patient transplants.
It sounds like science fiction, but researchers from the University of Missouri have a 3D printer that could one day recreate human organs by using a cocktail made from human cells. If your liver was failing, for instance, cells from...
