Science fiction is moving toward science fact, and that can be good news for a lot of people.
University of Texas scientists grew a human lung in a laboratory. Then, they did it again.
The lungs were grown from cells obtained from the lungs of children who were killed in an accident. Their lungs were too damaged to be used in transplant. Joan Nichols, a researcher at the University of Texas, Medical Branch, says it will be about 12 years before laboratory-grown lungs are ready to be used in human transplants.
If the CNN story is accurate, nobody was killed, paid money to have their body harvested, or was otherwise exploited to grow these lungs. That means there is no moral impediment to using them when they become available.
